Abstract: A brake system of a motor vehicle can activate a brake when an activation condition exists. The braking effect is reduced when a deactivation condition exists. It is suggested that at least one property of the reduction of the braking effect, e.g., the duration or the gradient of the reduction, be at least temporarily a function of a longitudinal inclination of the motor vehicle.

Abstract: In a method for assisting a driver during a hill start, the vehicle is held automatically at a standstill using a brake, and when a starting command is detected, the brake is released automatically if the engine torque or an equivalent variable exceeds a specified release threshold value. The vehicle is able to be prevented from rolling back, when the brake is released, by monitoring the engine torque or the equivalent variable for a change which is not due to the actuation of the accelerator, and by modifying the condition for releasing the brake when a change in the engine torque or in the equivalent variable has been detected.

Abstract: A process and device for controlling the brake system of a motor vehicle with all-wheel drive are described. The process and the device include an electronic control unit which controls at least one coupling unit for engaging and disengaging an all-wheel drive, so that at least one wheel can be decoupled, from the drive. After stopping the motor vehicle, for example on a sloping roadway, a predefined brake pressure on at least one wheel of the motor vehicle is held either depending on or independently from the extent of brake pedal actuation. The brake pressure is held until a brake pressure reduction condition is present, such as during a brake pressure holding time. During that time, the brake pressure on at least the one wheel is reduced and the wheel is decoupled from the drive to detect slippage, while at least one other wheel remains pressurized with brake pressure.

Abstract: A method for controlling the braking system of a motor vehicle in which, in order to prevent the vehicle from rolling away after a stopping action, a first braking force value is established at at least one wheel of the vehicle, independently of the driver, and is held for a predefined limited holding time; a transverse variable characterizing a transverse motion of the vehicle is ascertained; and as a function of the transverse variable, a release of the braking force is accomplished even before the predefined holding time has elapsed.

Abstract: A method for securing a stationary vehicle against unintended rolling, in which the braking pressure occurring in a braking operation is automatically locked in at a plurality of wheel brakes in order to keep the vehicle at standstill, and in which a sliding test is implemented in addition in order to detect sliding of the vehicle. The running time of a pump for reducing the braking pressure at the wheel brake of a test wheel may be shortened considerably if the generation of braking pressure at the wheel brake of the remaining wheel is restricted or completely prevented since less or no brake fluid has to be pumped out in this case.

Abstract: A method and device for determining the offset value of a longitudinal acceleration sensor, a first inclination variable representing the road surface inclination being determined from the output signal of the longitudinal acceleration sensor when the vehicle is standing still with the brake applied; a second inclination variable representing the road surface inclination and the vehicle acceleration being determined from the output signal of the longitudinal acceleration sensor after the brake is released following the vehicle standstill and the offset value of the longitudinal acceleration sensor being determined as a function of both inclination variables.
