- Vehicle V4 is not positioned in parking area Z1.
- the right front sensor S2 of vehicles V1 and V2 receives the radiation emitted by the source LS, while the other sensors of vehicles V1, V2 do not receive this radiation since they are located outside the emission field of the source LS .
- Only the left rear sensor S13 of the V3 vehicle is in the emission field of the LS source.
- the left front sensor S3 of the V4 vehicle receives the radiation emitted by the LS source, while the other sensors of the V4 vehicle do not receive this radiation since they are located outside the emission field of the LS source.
- the control unit CU is configured to determine that a vehicle V1-V4 is correctly placed in the parking area Z1, on the basis of the identifier transmitted by the data signals received by the different sensors. In the case of vehicles V1, V2, the control unit CU determines that the data signals received by the front right sensors S2, S3 are correct (the source identifier LS is received only by the front right sensor S2) , and that other sensors, and in particular the S4 sensor of the vehicles, do not receive these data signals, indicating that they are substantially vertical. The control unit CU deduces that the vehicles V1 and V2 are correctly positioned in the parking area Z1.
- the control unit CU determines that the data signals emitted by the source LS are not received by the right front sensor S2 and therefore that the vehicle V3 is incorrectly positioned in the parking area Z1 .
- the control unit CU determines that the data signals emitted by the source LS are not received by the front sensor S2, but by the left front sensor S3, and therefore that the vehicle V3 is positioned has upside down in relation to the required position on parking area Z1.
- the Cil control unit can determine that an end of rental is only authorized for vehicles V1, V2.
- control unit Cil can thus determine the position of a frame of reference V,x,y linked to the vehicle in the frame of reference OXY of one of the emission devices LS, LS1 having transmitted an identifier to the control unit CU.
- the control unit CU can also transmit the position of the V,x,y reference frame to the CSV server.
- the sensors installed on vehicles can be replaced by sources of electromagnetic radiation and the LS source can be replaced by an electromagnetic radiation sensor.
- a control unit connected to the sensor can locate the vehicles and
- the sensors S1-S4, S11-S13 are simple photovoltaic cells. More generally, sensors are elements sensitive to a band of wavelengths of electromagnetic radiation and provide an electrical signal representative of variations in intensity or wavelength of the radiation received.
- one or more of the sensors S1-S4, S11-S13 can be image sensors, for example cameras.
- the command to be executed by the vehicle can be determined based on a color appearing in the image provided by the image sensor.
- the image provided by a camera can be analyzed to determine whether a traffic light is visible in the image and is red or green, the command provided to the vehicle V1 being determined accordingly.
- the vehicle V1 may only be equipped with two sensors, for example a sensor at the front of the vehicle and a sensor at the rear of the latter, in particular if it is necessary to evaluate only the position and direction Vx of the vehicle V1 in a movement plane OX,Y linked to the signal emission devices LS. Furthermore, if we only seek to force users to return vehicles at the end of their rental to certain parking areas (for example Z1), a single sensor installed on the vehicle is sufficient to detect that the vehicle is indeed in one of the parking areas. these areas.
- Figure 16 illustrates different situations that can be managed by the Cil control unit.
- Figure 16 shows a zone Z10 receiving an electromagnetic field emitted by a source LS10.
- the identifier transmitted by the LS10 source corresponds to an area where the circulation of V1 vehicles is prohibited.
- the control unit CU is configured to stop the engine ENG of the vehicle V1.
- Figure 16 shows a zone Z11 receiving an electromagnetic field emitted by a source LS11, located at the entrance to a zone Z12 where the speed is limited.
- the control unit CU of the vehicle V1 Upon reception of the signal emitted by the source LS11, the control unit CU of the vehicle V1 is configured to control the motor ENG of the vehicle V1, in order to reduce the speed of the vehicle to reach the maximum authorized speed.
- Figure 16 shows pedestrian crossing zones Z13, Z14, receiving an electromagnetic field emitted by sources LS13, LS14 respectively.
- the control unit CU Upon reception of the signal emitted by the source LS13 or LS14, the control unit CU is configured to control the motor ENG of the vehicle V1, in order to reduce the speed of the vehicle to reach the speed set for crossing pedestrian crossings .
- Figure 16 shows a zone Z15 receiving an electromagnetic field emitted by a source LS15, located at the entrance to a zone Z16 where vehicles coming from another direction have priority.
- the control unit CU Upon reception of the signal emitted by the source LS15, the control unit CU is configured to control the motor ENG of the vehicle V1, in order to reduce the speed of the vehicle to reach a speed allowing the immediate stopping of the vehicle in the event of presence of another vehicle in zone Z16.
- Figure 16 shows a zone Z17 receiving an electromagnetic field emitted by a source LS17, located at the entrance to a zone Z16 comprising a traffic light or a stop sign.
- the control unit CU Upon reception of the signal emitted by the source LS17, the control unit CU is configured to control the motor ENG of the vehicle V1, in order to reduce the speed of the vehicle to reach a speed allowing the immediate stopping of the vehicle at the stop sign or at the traffic light.
- the signal emitted by the emission device LS is generated by powering a light source such as an LED diode ("Light Emitting Diode”) using a signal modulated in SPWM ("Sinusoidal Pulse Width Modulation") whose frequency can be fixed at a value greater than 1 MHz, the signal having a duty cycle modulated sinusoidally at a frequency between 1 and 22 kHz.
- Figure 17 shows curves C1, C2, variation as a function of time, curve C1 corresponding to the power supply signal of the source LS, and curve C2 corresponding to the resulting signal emitted by the source LS, as it can be received by one of the sensors S1-S4, S11-S13 of the vehicle V1.
- the remanence of the light source makes it possible to obtain a substantially sinusoidal signal when the duty cycle of the power supply signal of the light source is varied in a certain way.
- Data transmission to the processing unit CU can be carried out by varying the frequency of the sinusoidal signal thus produced.
- the emitters of electromagnetic radiation are for example light sources (visible light) or sources in infrared wavelengths (from near infrared to far infrared), knowing that at longer wavelengths , the fields emitted are less easily channelable.
- the present invention is capable of various embodiments and various applications.
- the invention is not limited to the arrangement of emitters of electromagnetic radiation at fixed points and receivers on mobile objects.
- the receivers can be fixed and the transmitters can be placed on the mobile objects, without departing from the scope of the present invention.
- a control unit is connected to each receiver and can thus identify moving objects and, for example, send them commands via another transmission channel.
- Figure 18 represents a mobile object V10 which differs from the vehicle V1 in that the sensors are replaced by a source LS21 of electromagnetic radiation (or several).
- the source LS21 continuously or periodically emits a data signal comprising an identifier of the moving object V10.
- Fixed sensors such as sensor S21 are arranged in the environment of the mobile object V10.
- a shutter device is associated with the source LS21 or the sensor S21 to limit the transmission field between the source LS21 and the sensor S21 to a field F21.
- the data signals received by the sensor S21 are transmitted to a processing unit CU1, for example the CSV server, which processes these signals to extract the data comprising the identifier of the mobile object V10.
- the processing unit CU1 can be configured to determine an order to be transmitted to the mobile object V10, taking into account the position of the sensor S21, known to the processing unit, and the identifier of the mobile object transmitted to the sensor by the data signals.
- the order thus determined by the processing unit CU1 can be transmitted by the processing unit to the processing unit CU of the mobile object V10 via another transmission channel, for example by a wireless network such as a WiFi type network or a mobile network or even a Bluetooth type connection which can thus be established automatically by due to the proximity between the fixed point and the moving object.
- the control unit CU1 can also control devices external to the moving object
- the command to be executed issued by the processing unit CU1 is not necessarily intended for the mobile object V10, but it can be executed by a device DV to be controlled located near the fixed point and connected to the control unit.
- the DV device can be, for example, a door opening striker or a fixed anti-theft device, or a device for emitting a signal or a sound, light or video message.
- the mobile object can simply be a badge worn by a user and having a device for emitting the data signal in the form of electromagnetic radiation.
- the command to be executed may be the triggering of the opening of a door or the broadcasting of a sound, light or video message in relation to an object in the immediate environment of the fixed point, for example a work of art or a machine.
- the concealment device can be associated with the receiver device S21 arranged at the fixed point to limit the zone where the mobile object must be located to trigger the command by the control unit CU1 connected to the receiver device S21.
- the concealment device can also be associated with the LS21 source.
- the invention is also not limited to the control of a fleet of vehicles in an urban space, but also applies to the control of a single vehicle or more generally, to the control of one or more mobile objects in a open or closed space such as inside a building.
- the invention can also be used in any other space, as long as this space is equipped with at least one emitter of electromagnetic radiation.
- Mobile objects can be, for example, drones or robots.
- the invention is also not limited to a mobile object equipped with several sensors. Indeed, a single sensor can be sufficient to determine in particular whether the mobile object is in an authorized zone or not, or more generally a zone where the command must be activated.
- the identification signal which is transmitted by modulating electromagnetic radiation may simply be an indication of the type of zone, such as parking, pedestrian zone, one-way or prohibited lane, proximity to a pedestrian crossing, etc.
- the data signal is not necessarily transmitted by modulating the intensity of the electromagnetic radiation. Indeed, other known types of modulation can be implemented such as frequency modulation or modulation of the pulse width, the radiation being emitted in the form of trains of pulses.
