Definitions
- the present invention relates to a bimodal circulation system, preferably electrically powered, one of the modes being conventionally controlled by the driver and the other controlled in a highly automated manner, comprising:
- the object of the present invention is to provide on the central aisle of the separate traffic lanes an own site running track for one of the sets of side wheels of equipped vehicles forming a mechanical guidance device having a shape of "gutter” by the cooperation of two lateral surfaces located one on the bottom of the protection wall "cast in place” which is generalized and the other on the lateral face of a continuous rail anchored in the roadway bordering said path bearing.
- This device on its own site, which advantageously uses the dead space between the protective wall and the continuous edge line delimiting the fast traffic lane, called a derased zone which does not encroach on the existing traffic lanes, allows highly automated traffic secured for equipped vehicles sharing the roadway, laterally offset with existing traffic, in order to allow an economically viable transition for a gradual deployment of a highly automated traffic mode.
- the present invention provides a new solution for the entrances and exits of the "gutter" of own site by providing a means of lateral crossing of the internal lateral surface by the assembly of lateral wheels, at sustained speed (which can be the maximum speed common in most countries on the motorway).
- sustained speed which can be the maximum speed common in most countries on the motorway.
- retractable rollers placed on the rockets of the side wheels of one of the sets of side wheels make it possible to temporarily relieve the load on the side wheels, by resting on the extension of the roadway when said side wheels are plumb. of the gutter for the purpose of depositing, without impact, and extracting said set of side wheels also at sustained speed.
- the main function of this device lies in the existence, for the equipped vehicle traveling with a set of its side wheels in the gutter, of an emergency mechanical lateral guide to control its trajectory in the event of degraded mode due to the fact failure of the primary steering system in highly automated mode. Therefore, the highly automated mode of circulation according to the invention allows the vehicle to enter and exit laterally at any point of the shared infrastructure and this at a speed more important than in the case where it is necessary to enter the network by a specific entrance door as is the case in the "O-Bru" system.
- this own site runway can be bordered directly by the protective wall of the "Jersey” type or other separating the lanes of a road with separate carriageway, the lateral surface bordering the runway being carried by the lower part of the "Jersey” wall thus advantageously using the smoothed strip located between the "Jersey” wall and the continuous white edge line delimiting the track.
- this track dedicated to vehicle guidance retains the infrastructure thus modified, all its characteristics to be used also by existing vehicles controlled by the driver, greatly facilitating the introduction of the system and leaving complete freedom to a more or less rapid increase in the fleet of vehicles equipped according to the invention without requiring significant initial investments .
- the side wheels can be equipped with adjustable height suspensions, the height of which will vary in synchronization with the movement of the rollers to minimize body roll.
- adjustable height suspensions the height of which will vary in synchronization with the movement of the rollers to minimize body roll.
- a control of the vehicle direction can thus maintain the front wheels in the center of the clean-site runway, thus offering a simplified, highly automated driving mode that does not require visual detection of the edge lines.
- the present invention aims to provide electric mobility with a dynamic power supply at very low voltage, arranged along the traffic lanes from which each vehicle can be powered at a voltage of less than 50 V in alternating and 120V in direct in order to respect the safety standards. It is recalled that although lower than 400 V, the standard voltage of the battery pack, the very low safety voltage of 120V continuous allows all the same to charge successively by switching each section of approximately 100V of the battery pack, the batteries being composed of elements of tension of a few volts only.
- the "Jersey" wall comprises above the first lateral guide surface on each side a "third rail” connected to one of the very low voltage source poles and the vehicle has a lateral sliding contact to ensure the power supply to the vehicle while driving, the other pole, connected to the rail, being picked up by a brush or any other known device.
- the present invention makes it possible to substantially limit the capacity and therefore the weight of the on-board battery pack, thus reducing the quantity of C02 generated for its production.
- the very low voltage of 120 V DC collected directly by sliding / rolling contact makes it possible to supply the motor directly in autotransformer mode, without going through the batteries, the latter only serving to provide temporary additional energy or to recover the excess energy due to ascents / descents and speed changes imposed by the profile of the lane in highly automated traffic mode.
- the object of the present invention is to reduce the current congestions of the network by allowing the movement in a "platoon" of several vehicles while mitigating the dangerousness of such a system, which in essence greatly reduces the distances of the vehicles of the platoon. , by an on-board emergency braking device.
- an emergency brake caliper allowing deceleration of up to several g, is attached to the rear of the vehicle, preferably behind the rear wheel to allow its engagement and disengagement of the rail when entering and exiting the highly automated mode according to the invention.
- This device advantageously makes it possible to maximize the reaction time for the management of fleeting or permanent obstacles that may be on the track by substantially reducing the braking distance which can thus be of the same order or less than the 2 seconds prescribed for current speeds on tracks. rapids or highways. Consequently, the emergency braking device according to the invention increases, on the one hand, the time allocated to the analysis of the nature of the obstacle and, on the other hand, is free from the degradation of braking performance over time. wet or icing.
- this braking will be associated with a telescopic stopper placed in the front bumper of vehicles which operates by inertia, as on heavy towed trailers, by mechanically actuating the emergency brake caliper, in degraded mode, in case of failure of the on-board control system or total "black-out".
- the invention thus advantageously makes it possible to increase the traffic flow without necessarily requiring the creation of additional lanes on the roadway as is the case today, and therefore represents a substantial economic and environmental benefit.
- the invention instead of having to widen a motorway to two times three lanes when the traffic exceeds, at peak, the 4,000 vehicles / hour, the invention will make it possible to increase the flow to more than 6,000 vehicles / hour at sustained speed and this for a fraction of the cost necessary to create a third channel.
- lateral guidance to keep the vehicle in degraded mode on its path will advantageously consist of sections connected together allowing by clamping and friction to transmit the few tens of tons that the braking force of an assembly vehicle traveling "in a platoon" could impose on him.
- the traffic system for motor vehicles comprises on the side of a traffic lane a clean site runway, in the shape of a "U" gutter, accommodating in highly automated driving one of the sets of side wheels d '' a vehicle and comprising:
- the lateral crossing means of the internal lateral surface may be constituted by a ramp, generally gently sloping perpendicular to the direction of movement, which connects the roadway to the upper end of the internal lateral surface.
- the lateral crossing means of the internal lateral surface can be obtained by arranging the running surface of the own site running track at a height lower than the roadway.
- the lateral crossing means of the internal lateral surface can be obtained by the combination:
- the upper end of the inner side surface comprises an auxiliary rolling surface, substantially parallel to the rolling surface and the front wheel of the side wheel assembly is equipped with an auxiliary support means capable, while rolling at cruising speed, to temporarily relieve the load on the front wheel by resting on the auxiliary rolling surface, the auxiliary support means being retractable by displacement between a high position, where it preserves the ground clearance of the vehicle and a position low where its lower contact point is substantially at the same height as the point of contact of the front wheel with the roadway.
- the auxiliary support means comprises at least one caster mounted on a support arm articulated on the axle knuckle of the front wheel of the side wheel assembly and the inner side surface and the auxiliary rolling surface are carried by a rail. continued.
- the rail comprises a third ledge surface, substantially parallel and below the auxiliary rolling surface, the third surface and the auxiliary surface being able to be clamped by an emergency brake caliper connected to the structure of the vehicle for generate a braking force, by friction on the rail, which can urgently reach a high value greater than 1 g, regardless of the coefficient of adhesion between the wheel and the roadway.
- the set of side wheels can be fitted with variable height suspensions and the heights of the suspensions:
- a sensor In front of the set of side wheels, a sensor measures the lateral distance between the set of side wheels and the outer side surfaces of the clean site running track and controls the steering device of the vehicle to maintain, while driving, the side wheels of the side wheel assembly generally centered on the clean site track.
- the yaw torque generated during emergency braking between:

- FIGs 5, 7 and 9 represent in axisymmetric views the transition sequence from free driving to driving in highly automated mode, by crossing the ramp by the assembly of the side wheels and then depositing it in the "gutter" according to the invention.
- FIGs 6, 8 and 10 represent enlargements of Figures 5, 7 and 9 with the vehicle in transparency to illustrate the casters temporarily allowing the weight of the vehicle to be relieved during the passage from free mode to highly automated mode.
- FIG 11 [Fig 12] [Fig 13] - Figures 11, 12 and 13 represent, in front view, the coordination of the height-adjustable suspension with the lateral displacement of the vehicle according to the invention to minimize / cancel the roll checkout when entering and exiting the highly automated driving mode.

- FIG 18 [Fig 19] - Figures 18 and 19 show front views of own site infrastructure of the toboggan or underground type advantageously using the reduction of traffic lanes thanks to the highly automated traffic means according to the invention.
- Figure 1 illustrates a dual carriageway or highway “a” with traffic “on the right” comprising the traffic lanes “b” and “c” separated by a concrete guardrail 1 type “New Jersey” known. Conventionally, we find successively from the outside to the inside:
- Light vehicles D and heavy goods vehicles E circulate on the tracks 11 and 12 in a conventional manner, under the control of their drivers, who keep their vehicles substantially centered on the tracks.
- the light vehicles Fl to F6 circulate on horseback on the shore line 4b or 4c in a "platoon” and in a highly automated manner, in pseudo 4/5 mode (according to the SAE standard commonly defined by the authorities and automobile manufacturers ), without requiring particular vigilance from their drivers, the vehicles F moving straddling the edge lines 4b or 4c.
- FIGS 2 and 3 illustrate a cross section of the central part of the road "a".
- the concrete safety barrier 1 and two weir channels 17b and 17c of the known type "slotted pipe” in prefabricated concrete comprising an evacuation pipe 18 supplied by flow slots located in the flattened bands 13b and 13c.
- the gutters 17b and 17c are buried on either side at the base of the concrete guardrail 1.
- the vehicles F2 and F4 have their sets of left wheels engaged in the "U" "gutters" 21b, 21c comprising:
- This insulating support 25 can advantageously house the cables 26, at medium voltage, supplying the substations delivering very low voltage to the vertical conductive surface 24.
- a ramp 34 gently sloping substantially the height of the rail 27, formed of ramp segments is fixed on the attachment wing of the rail 29.
- the substantially vertical side surfaces 23 and 31 serve as side edges, in degraded mode, to keep the side wheels on the raceway by contact between the sidewalls of the tires of the side wheels 35 and 36, or the edge of the rim in the event of a puncture, and the side surfaces 23 and 31.
- This degraded mode only intervenes in the event of failure of the steering control device (not illustrated) which is already fitted to some cars with an automated driving mode. of type 3.
- this steering control device is simplified, not requiring optical recognition, and being able to be satisfied with a simple lateral distance telemetry by ultrasonic sensors 33, for example, to hold the front wheel 35 of the vehicle. vehicle centered on the running surface 22 in highly automated traffic mode according to the invention.
- FIG. 4 illustrates a light electric vehicle F which comprises the devices necessary for circulation in highly automated mode according to the invention. This is a vehicle traveling "on the right", comprising a set of left side wheels 16 comprising the following devices specific to the invention:
- a device for measuring the lateral distance 33 advantageously multi-sensor, preferably located in front of the front right wheel 35;
- a crossing means consisting of two sets 8, each set comprising a roller 38, 39 which can be lifted, the support arm 14 of which is actuated by the actuator 15, preferably electric, being attached to rockets 9 of the two left wheels 35 and 36 and;
- Figures 5-6, 7-8 and 9-10 illustrate the sequence of switching from conventional driving under the responsibility of the driver to the highly automated traffic mode according to the invention.
- the reverse sequence allows the disengagement of the highly automated traffic mode according to the invention to conventional driving under the responsibility of the driver.
- the vehicle F travels on the conventional track 12b bordered by two edge lines, discontinuous on the right 3b and continuous on the left 4b.
- the set of distance sensors 33 measures the distance which separates the vehicle F from the concrete guardrail 1.
- the casters 38 and 39 are raised as well as the retractable slider 37 and the emergency brake caliper 40 is raised and is behind the wheel 36. If the system has detected the existence, by a geolocation system for example, of an arrangement of the leveled strip according to the invention, that the distance from the concrete rail 1 is equal to a certain value and the speed is sufficient, the change of driving mode can be initiated by the driver.
- the vehicle F having initiated the change of driving mode, moves to the left autonomously while driving at cruising speed, the left wheels 35 and 36 cross the bank line 4b and rise on the ramp 34, simultaneously the rollers 38 and 39 are lowered by the rotation of the support arms 14 actuated by the jacks 15 and when the wheels 35 and 36 are in line with the rolling surface 22, the casters 38 and 39 resting on the upper rolling surface 32 of the rail 27 temporarily support the load of the wheels 35 and 36. By raising the rollers 38 and 39 deposit the wheels 35 and 36 on the rolling surface 22.
- the vehicle F has deployed the retractable slider 37 located at the left side sill which has come into sliding / rolling contact with the conductive surface 24 which may advantageously be made of aluminum to minimize losses by effect joule with a steel contact surface, a brush or a rolling / sliding contact 56 (behind the cylinder 53) is in contact with the steel rail 27 to establish the return of current and thus a dynamic power supply with a power of the order of 25-30 kW per vehicle is thus achieved.
- the brake caliper 40 has tilted and engaged the rail 27.
- the roller 41, resting on the rail 27, maintains the linings 42 of the caliper 40 in proximity to the three continuous surfaces 30, 31 and 32 without touching them.
- the vehicles Fl, F2, F3 and F4, F5, F6 can advantageously regroup in a platoon with a distance of less than 1 m between vehicles as illustrated in FIG. 1.
- This allows a substantial increase in the flow of traffic lanes 12b and 12c by the platooning of 2 or more vehicles.
- platoons of 3 to 4 vehicles this is a 250% increase in the maximum flow of vehicles / hour, which goes from around 1,700 vehicles / hour to nearly 6,000 vehicles / hour for the equipped traffic lane.
- Known devices for measuring close distance, by ultrasound for example maintain reduced "intra-peloton" distances between vehicles allowing a substantial gain in aerodynamic drag.
- the vehicles thus grouped together can nevertheless leave the peloton at any time by a communication device between the vehicles of the "Wi-Fi", "Bluetooth” or similar type. Indeed, before a junction of separate lanes, and not a simple exit which will in any case require a resumption of the conventional traffic mode, if the vehicle has to take the right branch, it will have to leave the highly automated traffic mode and not will only be able to re-engage the highly automated traffic mode when it has entered the right-hand branch.
- the vehicle wishing to leave the peloton informs the vehicles in front and behind which will automatically reduce or increase their speed to restore a regulatory separation distance of 2 seconds.
- a vehicle also equipped with level 3 autonomous driving can perform without driver intervention. , but under his vigilance, the disengagement maneuver of the wheels 35 and 36 from the gutter 21 before the branch, then the change of lane to take in free mode the right branch of the branch and then the re-engagement in the gutter 21 of the right branch.
- Reference beacons installed on these branching areas can help the basic autonomous system, since it is level 3, to precisely locate the vehicle in relation to the infrastructure in the event of reduced visibility (night, rain, fog, etc.) .
- Figures 11, 12 and 13 illustrate the sequence of switching from the conventional driving mode under the responsibility of the driver to the highly automated mode according to the invention in the case of a vehicle with variable suspension height, thus advantageously allowing to reduce or even cancel any vertical movement and / or body roll during this sequence.
- Figure 11 shows, in front view, the vehicle F5 with "variable height suspension” traveling on a conventional track 12c.
- the lateral distance measuring device 33 measures the distance which separates the vehicle F5 from the concrete guardrail 1, the roller 38 then being raised; if the measured distance has a certain value, and the speed is sufficient to fit into the highly automated traffic mode, a driving mode change can be initiated by the driver.
- Figures 12 and 13 illustrate the vehicle F5 which while driving at cruising speed will engage on the gutter 21 by shifting to the left, the left front wheel 35 crosses the bank line 4b and when goes up on the ramp 34, the right side suspensions 51 gradually rise while those on the left side 52 lower to cancel the roll, simultaneously the rollers 38 and 39 are lowered and when the left wheels 35 and 36 are at the Plumb with the running surface 22, the height of the suspensions of the left wheels 52 increases to gently deposit the wheel 35 and the wheel 36 (hidden by the wheel 35) on the running surface 22.
- the caster 38 and the caster 39 (masked by the roller 38) which temporarily took up the loads from the wheels 35 and 36 retract so that the wheels 35 and 36 only carry the lateral weight of the vehicle F5.
- Figure 14 illustrates in particular an advantageous junction system for the rail sections 29 which form the continuous rail 27 of the mortise tenon type uncovered. Therefore the front end of the rail section 27 in the direction of travel is uncovered mortise 29b and the rear end uncovered tenon 29a and the assembly can be done for example by three braked BTR screws.
- the end of the tenon 29a and the mortise 29b will be inclined in the vertical and horizontal planes to avoid a complete discontinuity in the height of the surfaces in a transverse plane. This system advantageously allows a tolerance on the length of the rail sections 29, facilitating their maintenance or replacement.
- FIGs 14 and 15 illustrate the emergency braking system according to the invention which allows a platoon of light vehicles at short inter-vehicle distance.
- This system is particularly suitable for mitigating the risk of collisions in highly automated operation where the trajectory and speed are beyond the driver's control and his vigilance is not sustained. Indeed, thanks to an exploration of the lane by radar or any other method making it possible to detect the vehicles or obstacles located on the trajectory, the control system adapts the speed of the vehicle, but in the case of the unexpected occurrence of a fixed obstacle or stopped / accidented vehicle, the capacity of strong emergency deceleration, whatever the weather conditions, of the single vehicle or of vehicles forming a platoon according to the invention, is thus much greater than what can be obtained by the vehicles.
- conventional vehicle braking means which are limited by the wheel / road friction coefficient usually less than 1.
- the brake caliper 40 is engaged on the continuous rail 27 by rotation about the axes 48 and 49 which allow a tolerance on the height, the wheel 41 maintaining the brake linings 42 fitted to the three faces of the caliper in the immediate vicinity of the surfaces 30, 31 and 32 of the continuous rail 27.
- the vertical piston (or pistons) 53 is preferably located on the upper part of the caliper 40.
- the pin 46 of the support 45 is engaged in the hole 44 to prevent any rotation of the caliper relative to the rear axle on a transverse axis due to the eccentricity of the caliper 40 relative to its tilting axes 48 and 49.
- Figures 16 and 17 illustrate the forces that are at stake during high power emergency braking which generates a yaw torque due to the lateral offset between the braking force 57 of the vehicle, exerted on the continuous rail 27, and the inertia force 50 substantially in the longitudinal plane of symmetry of the vehicle.
- This couple is advantageously taken up by the couple between:
- FIG. 18 illustrates an example of an aerial "toboggan" walkway 61 of a clean site of low cost due to the low weight of light vehicles moving according to the highly automated traffic mode according to the invention, allowing the crossing of an urban area. , pedestrian, road, highway, railway, river, etc ....
- Figure 19 illustrates the small dimensions of the tunnel 62 necessary for the proper site traffic of light vehicles moving according to the highly automated traffic mode according to the invention due to the precise lateral positioning of the vehicles.
- the system according to the invention providing the advantage of leaving great freedom over the width vehicles compared to the solution based on exterior casters adopted by the "Tracline 65", “O Bahn” projects and more recently by Elon Musk's "Boring Company”.
- the devices described above of the invention, allowing the lateral entry and exit of the highly automated traffic mode according to the invention on a road infrastructure in cohabitation with vehicles traveling in free mode, are particularly advantageous for solving the problem. problem posed by entering and leaving lanes on their own, exclusively reserved for light vehicles, as illustrated in figures 18 and 19.
- a substantial advantage of increased road mobility, according to the invention, is to make it possible to achieve, without heavy investments, a transition between the movement of vehicles in free mode and in highly automated mode of circulation according to the invention on existing infrastructure.
- Another substantial advantage of increased road mobility according to the invention is the reduction in the size of the battery of "100% electric” vehicles which can now be limited to a capacity necessary to cover a distance of less than 100 between recharges. km, representing a division by a factor of 3 to 5 of the weight of the batteries with an impact on the weight, the cost, the need to strengthen the thermal design vehicle and the environmental impact imposed to date by the size of the batteries of last generation on electro mobility in "free circulation".
- the devices according to the invention can be adapted to other configurations of road with separate lanes, in particular roads with only one lane in each direction, other forms of gutters and rails or to other vehicle structures and Examples which have just been given are only specific illustrations in no way limiting the fields of application of the invention.
