Definitions
- the invention relates to a method for operating an anti-lock motor vehicle brake system for driving stability and / or traction control, which has a pneumatic brake booster that can be actuated independently of the driver's will and a master brake cylinder connected downstream of the brake booster -Hydro unit the wheel brakes assigned to the individual vehicle wheels are connected.
- a brake system is known from DE-42 08 496 Cl, whose brake booster interacts with a solenoid valve to implement an automatically controlled braking process associated with a high vehicle deceleration, which enables increased brake pressure development when the brake pedal is pressed quickly .
- a brake pedal position transmitter e.g. a brake pedal position transmitter, a brake light switch and a force sensor enabling detection of a driver's deceleration are provided.
- the known brake system provides an anti-lock control system (ABS), which ensures stable deceleration behavior of the vehicle when braking.
- ABS anti-lock control system
- a disadvantage of the brake system described therein is the relatively high consumption of vacuum volume during the control or the unavailable pressure availability. It is therefore an object of the present invention to propose a method for operating an anti-lock motor vehicle brake system of the type mentioned at the outset which enables the consumption of vacuum volume to be minimized during the control.
- this object is achieved in that, when entering the control, the brake booster is fully controlled independently of the driver's will and the desired wheel brake pressures are set with the aid of the ABS hydraulic unit, with the external control of the brake booster only at the end of the control is then switched off when the brake booster has been brought back to its starting position by returning the pressure medium discharged from the wheel brakes into the low-pressure accumulator. It is thereby achieved that the pressure equalization between the working and the vacuum chamber of the brake booster after switching off means only a small loss in the vacuum volume or actuating energy.
- the operation of the brake system described with simultaneous operation by the driver and external control is made possible according to a further feature of the invention in that the actuation of the brake booster by the driver is sensed and the external braking is changed accordingly.
- This measure ensures that the transmission of driver and external braking is a software measure and can therefore be freely configured in accordance with the requirements of the vehicle control system.
- indirect detection of the driver's deceleration request is ensured by determining the actuation path of a brake pedal actuating the brake booster, the brake pedal not being moved when the brake booster is activated independently of the driver's will.
- the determined actuation path is preferably converted into an actuation force or a vehicle deceleration setpoint by means of a predetermined characteristic curve or learned during normal braking.
- an exact determination of the driver's deceleration request is made possible by the fact that the actuating force initiated with the brake pedal is sensed.
- an advantageous further development of the subject matter of the invention provides that the vehicle engine is throttled if the negative pressure in the negative pressure chamber of the brake booster is too low.
- the engine intervention is preferably carried out by means of the so-called E-gas. _ 4 _
- the invention provides that the pressure is determined by means of pressure sensors connected to the pressure chambers of the master cylinder.
- the single figure shows an embodiment of an anti-lock motor vehicle brake system with which the method according to the invention can be implemented.
- the brake system shown in the drawing for performing the method according to the invention has two brake circuits I and II, the structure of which is completely identical, so that the following description of one brake circuit also applies to the other.
- the brake system shown consists essentially of a brake pressure sensor 1, to which wheel brake cylinders 17, 18 can be connected via hydraulic lines (not specified), an ABS hydraulic unit 2 connected between brake pressure sensor 1 and the wheel brakes, and an electronic controller 25 with associated sensors.
- the wheel brake cylinders 17, 18 of the individual brake circuits I, II are assigned in such a way that the first wheel brake cylinder 17 is either a wheel of a vehicle axle and the other wheel brake cylinder 18 the diagonally opposite wheel of the other vehicle axle is assigned (diagonal division of the brake circuits) or both wheel brake cylinders 17 and 18 are assigned to the same vehicle axis (black and white division of the brake circuits).
- the pressure transmitter 1, which can be actuated by the driver of the motor vehicle by means of a brake pedal 6, consists of a pneumatic brake booster 5 which is followed by a master brake cylinder, preferably a tandem master cylinder 3, the pressure chambers of which are not shown and can be connected to a pressure medium reservoir 4.
- An actuating rod 7 is coupled to the brake pedal 6, which enables the vehicle driver to actuate a control valve 8, which is only indicated schematically, and which controls the build-up of a pneumatic differential pressure in the housing of the brake booster 5.
- a brake light switch 14 that is operatively connected to the brake pedal 6 enables the driver to detect activation of the brake booster 5 or by actuating the electromagnet 26.
- the brake booster 5 is actuated externally, the brake pedal 6 is carried along and the brake light switch 14 is thus reversed.
- An operation initiated by the driver of the brake booster 5 can, for. B. can be recognized by the use of a release switch, not shown.
- the ABS hydraulic unit 2 has a motor-pump unit, which consists of a hydraulic return pump 13 driven by an electric motor, not shown. whose suction side is connected via a first check valve 9 to a low-pressure accumulator 27 assigned to the wheel brakes 17, 18. From the pressure side of the return pump 13, the pressure medium flows via a second check valve 10 and a damping chamber (not shown) to a hydraulic node 21. Connected to this are both a line section 19 leading to the first wheel brake cylinder 17 and a line section 20 leading to the second wheel brake cylinder 18 Hydraulic line 23 connects the pressure side of the return pump 13 to the tandem master cylinder 3.
- a motor-pump unit which consists of a hydraulic return pump 13 driven by an electric motor, not shown. whose suction side is connected via a first check valve 9 to a low-pressure accumulator 27 assigned to the wheel brakes 17, 18. From the pressure side of the return pump 13, the pressure medium flows via a second check valve 10 and a damping chamber (not shown) to a
- a parallel connection of an inlet valve (11) with a third check valve 22 and an outlet valve 12 are used, the parallel connection mentioned in the line section 19 is inserted and the outlet valve 12 enables a connection between the first wheel brake cylinder 17 and the low pressure accumulator 27 for the purpose of reducing the wheel brake pressure.
- a second parallel connection of a second inlet valve (15) with a fourth check valve 24 and a second outlet valve 16 are provided, the mentioned parallel connection is inserted in the line section 20 and the outlet valve 16 for the purpose of reducing the wheel brake pressure establishes a connection between the second wheel brake cylinder 18 and the low-pressure accumulator 27.
- a force sensor 28 which cooperates with the piston rod 7 articulated on the brake pedal 6 and serves to sense an actuation force initiated by the driver on the brake pedal 6, the signals of which are fed to the controller 25.
- means for Detection of the master brake cylinder pressures is provided, which are preferably formed by pressure sensors 32, 33 connected to the first and second brake circuits 1, 11, the output signals of which, together with further signals, for example information about the steering angle (LW), the wheel speeds ( ⁇ R ), and the vehicle reaction, such as the yaw rate (GWG) or the lateral acceleration (0- p ), are supplied to the electronic controller 25.
- the electronic controller 25 receives information about the state of the brake booster 5, z. B. the path of its movable wall.
- both pressure build-up and pressure reduction can take place in the wheel brake cylinders 17, 18 by corresponding actuation of the brake pressure sensor 1 via the open inlet valves 11, 15.
- the return pump 13 In the case of ABS standard braking, in which, for example, the wheel assigned to the wheel brake 17 threatens to lock up, the return pump 13 is started.
- the pressure is modulated by switching the inlet and outlet valves 11 and 12 accordingly, the pressure medium discharged into the low-pressure accumulator 27 being returned to the master cylinder pressure level by the return pump 13.
- the brake booster 5 When entering any external braking process, the brake booster 5 is fully controlled by means of electromagnets 26, regardless of the driver's will.
- the working chamber of the brake booster 5 has the smallest possible volume in the release position. This ensures that the pressure equalization between the working and vacuum chamber after the external control of the brake booster 5 has been switched off means only a small loss of vacuum, so that sufficient vacuum is still available for further external braking or driver braking. If external braking begins with an insufficiently developed vacuum level in the vacuum chamber of the brake booster 5, the electromagnetic controller 25, in cooperation with an engine controller 30, must throttle the vehicle engine 29, for example by E-gas intervention. An intervention in the drive management must be possible so that the control system can correct a driver acceleration request that is incompatible with the present driving situation if necessary.
