  • the purpose of such braking systems in motor vehicles is to store at least part of the energy recovered during braking in the vehicle and to reuse it for driving the vehicle. As a result, the energy consumption of the vehicle can be reduced overall, the efficiency can be increased and the operation can thus be made more economical.
  • a pair of hydraulic friction brakes for the deceleration of the front wheels of the Schuachs- wheels as they are known from ordinary motor vehicles, and used electric motor, which is operable as a generator. At least part of the total braking force is applied via the electric motor located in the generator mode.
  • the electrical energy obtained is fed or fed back into a storage medium such as an on-board battery and reused for driving the motor vehicle via a suitable drive.
  • This braking force of the electric motor arises from the known effect in electric motors which act as dynamo or generator with mechanical driving without supply of electric current and generate electric current. This creates a counterforce, which counteracts the mechanical drive and acts as a braking force in the present case.
  • the electric motor operated as a generator therefore acts as a brake.
  • the total braking force of the motor vehicle is therefore composed of the braking force of the hydraulically actuated wheel brakes, the braking force of the electromechanically actuated wheel brakes and the braking force of the electric motor acting as a generator. It is known that in such brake systems, the hydraulic connection between the brake pedal and the friction brakes must be temporarily disconnected or at least reduced in order to efficiently use the possible deceleration performance of the electric motor in generator operation and thus to store the recovered energy.

  • the exhaust valves are formed in the second brake circuit as normally closed, analog controllable valves.
  • the present task is procedurally achieved in that after the detection of a driver's braking request, the following method steps are carried out:
  • An advantageous development of the method according to the invention provides that the conveying of pressure medium from the Pressure medium reservoir into the wheel brakes of the second brake circuit in accordance with the driver's brake request is determined, which is determined by means of the pedal sensor.
  • the pressure introduced by the delivery of pressure medium into the wheel brakes of the second brake circuit is determined by a pressure sensor, so that pressure regulation can be carried out.
  • the output signals of the pressure sensor arranged in the second brake circuit are evaluated in such a way that a leakage in the second brake circuit can be determined.
  • FIG. 1 A circuit diagram of the vehicle brake system is shown in FIG. 1.
  • the vehicle brake system has, on the one hand, hydraulically actuable wheel brakes 1, 2 and, on the other hand, an electric motor 16, which generates a braking force in generator operation.
  • the electric motor 16 is used outside of the generator operation as a drive of the motor vehicle.
  • the hydraulically actuated wheel brakes 1, 2 are divided into two brake circuits I, II, wherein the wheel brakes 1 are arranged in the first brake circuit I and act on the wheels on a first axis of the motor vehicle, the front axle, while the wheel brakes 2 of the second brake circuit II on the wheels on a second axis of the motor vehicle, the rear axle, act.

  • the introduced pressure medium in the first brake circuit I of the front axle is discharged via outlet valves 8 into a low-pressure accumulator 23.
  • a pressure reduction takes place via the outlet valves 18 and the pressure medium line 6 in a pressureless pressure fluid reservoir 9.
  • the normally closed exhaust valves 18 in the second brake circuit II are formed as analog controllable valves.

  • the isolation valve 19 is an analog controllable normally open SO valve and is needed for all controls during an active pressure build-up by the hydraulic pump 22.
  • the isolation valve 19 is closed in these active pressure buildup phases, so that the pressure buildup is not controlled in the master cylinder 5.
  • the electrical switching valve 20 - also called EUV for short - is a normally closed SG-valve, the connection between the master cylinder. 5 and the suction side of the pump 22 establishes or interrupts.
  • the electrical changeover valve 20 is open and the pump 22 can suck in pressure medium via the master cylinder 5 from the pressure medium reservoir 9 and provide, for example, for a traction control.
  • the system described here is based on the basic idea that a brake control system known in principle is modified in such a way that the possibility of a pressure medium intake of the hydraulic pump 24 of the second brake circuit II from the pressure fluid reservoir 9 is provided.

  • the separating valve is closed and the second brake circuit II takes over the braking force control on the rear axle autonomously. Since the electric motor 16 in generator operation can only partially apply the required braking torque in some situations, the additionally required braking torque is generated by the hydraulic pump 24.
  • the suction side of the hydraulic pump 24 is connected directly to the pressureless pressure fluid reservoir 9 without the interposition of a hydraulic valve. As a result, the pump 24 can suck in pressure medium from the pressure medium reservoir 9 and convey it into the wheel brakes 2.

  • the braking force can be distributed independently of the driver pre-pressure between the recuperative braking unit in the form of the electric motor 16 in the generator mode and the wheel brake 2.
  • the suction valve usually required for sucking from the master cylinder 5 may also be omitted, since the pump 24 is connected directly to the pressure medium reservoir 9.
  • the present method now provides the following: When the vehicle driver actuates the brake pedal 3 and thus generates a braking request, this braking request sensed by the pedal sensor 11 is transmitted to the control and regulation unit 14. Subsequently, the separating valve 21 is closed and the second brake circuit II separated from the master cylinder 5. The electric motor 16 is operated in generator mode, so that the braking energy of the motor vehicle is recovered. So that at a comparatively low driver brake request no braking energy through the Friction of the wheel brakes 1 of the first brake circuit I is converted into heat and the recuperation is no longer available, the master cylinder 5 is equipped with a prolonged free travel.
  • This extended free travel ensures on the one hand that as just described no braking energy that could be recovered is converted into frictional heat and on the other hand, a simulator effect is achieved with the help of the extended idle travel to give the driver a consistent, pleasant pedal feel. If the braking torque generated by the electric motor 16 in generator mode is insufficient, ie smaller than required by the driver, the pump sucks 24 pressure fluid from the pressure fluid reservoir and promotes it in the wheel brakes 2. At the same time is the extended free travel of the master cylinder 5 in this situation greater driver brake request by the driver and hydraulic pressure medium is controlled via the open intake valves 7 in the wheel brakes 1 of the first brake circuit.
  • a particularly reliable fallback level is advantageous in the system described: If a fault is detected, which prevents safe control of the second brake circuit II, because for example, the valves 17, 18, 21 are not switchable or the pump 24 is not controlled, so can the Braking the driver as usual, since the second brake circuit to be controlled II is no longer separated from the master cylinder 5.
  • the driver has in this case only a slightly extended pedal travel.

Abstract

L'invention concerne une installation de freinage de véhicule ainsi qu'un procédé correspondant pour des véhicules automobiles, avec un système de freinage hydraulique qui présente un transmetteur de pression hydraulique (4) pouvant être actionné par pédale, avec un réservoir de fluide hydraulique sans pression (9) et un maître-cylindre (5) monté en aval, et qui est divisé par essieu en deux circuits de freinage (I, II). Les deux circuits de freinage (I, II) présentent chacun une pompe hydraulique (22, 24) pouvant être commandée de l'extérieur, une soupape de séparation (19, 21) et des freins de roue (1, 2) pouvant être actionnés hydrauliquement et pourvus de soupapes d'admission et d'évacuation (7, 8, 17, 18). Le premier circuit de freinage (I) présente en outre une soupape de commutation électrique (20). Les roues du deuxième essieu du véhicule sont entraînées au moins temporairement par un moteur électrique (16), qui peut être exploité en tant que générateur pour récupérer de l'énergie de freinage et qui, en mode de générateur, exerce une force de freinage sur les roues du deuxième essieu du véhicule. Un capteur de pédale (11) détermine le souhait de freinage du conducteur et le transmet à une unité (14) de commande et de réglage. Selon l'invention, le côté d'aspiration de la pompe hydraulique (24) du deuxième circuit de freinage (II) est directement relié au réservoir de fluide hydraulique sans pression (9), sans intercalation d'une soupape hydraulique, de sorte qu'on peut effectuer un pompage de fluide hydraulique depuis le réservoir de fluide hydraulique (9) dans les freins de roue (2) du deuxième circuit de freinage (II).
