    摘要: A method for operating a braking system of a motor vehicle equipped with a wheel-slip control device, wherein the braking system includes an electrohydraulic service brake, set to generate braking forces independently of an actuation by an operator. The system having a mechanical or electromechanical parking brake actuated by an actuating element, and acting, in particular, on the rear wheels of the motor vehicle. An operator-side intent to actuate the parking brake is recognized and subsequently during the actuation of the parking brake a hydraulic pressure of the service brake is generated that acts on at least one rear wheel, of the motor vehicle capable of being braked by the parking brake. The hydraulic pressure sufficient to assist the parking brake and correspondingly lock the rear wheel of the motor vehicle braked by the parking brake during travel of the motor vehicle.

    摘要: In the brake control device, a wheel-cylinder hydraulic pressure (Pw) obtained by adding the linear-valve pressure difference to a master-cylinder hydraulic pressure (Pm) is applied to the wheel cylinder while the vehicle is running. When an operation of a brake pedal is started while the vehicle is running (t1), the driving of the hydraulic pump is started. Thereafter, when the vehicle is stopped (t2), the driving of the hydraulic pump is stopped. When the start of movement of the vehicle is detected during an operation of returning the brake pedal (t4) and an operation of re-depressing the brake pedal is detected (t5) in this state (specifically, while the vehicle is in a stopped state, the hydraulic pump is in a stopped state, and the brake pedal is being operated), the driving of the hydraulic pump is started (t5).

    摘要: A method and system for controlling vehicle stability may comprise determining whether a vehicle is oversteering or understeering and, if the vehicle is oversteering or understeering, determining an amount by which to reduce a speed of the vehicle to correct for understeering or oversteering and applying brake pressure to at least the rear brakes of the vehicle to reduce vehicle speed. The method and system also may comprise determining an engine torque reduction amount based on vehicle oversteer or understeer conditions, reducing engine torque by the determined amount or to zero if the determined amount of engine torque reduction is greater than an actual engine torque, and applying braking to at least the rear brakes of the vehicle if the determined amount of engine torque reduction is greater than the actual engine torque.

    摘要: The invention relates to an electromechanical brake force booster for a hydraulic vehicle brake system. The invention proposes that the brake force booster be formed with two restoring springs, one of which acts on an electromechanical actuator and the other of which restoring springs acts on a pedal rod. In the event of failure of the electromechanical actuator, only the other spring, which preferably has a relatively low spring force, must be compressed using muscle force. The force loss in the event of actuation exclusively by muscle force is reduced.
