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: 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: In a device for securing the standstill of a motor vehicle with a distance-related longitudinal dynamic control module, which is contained in at least one electronic control unit and by which the motor vehicle is decelerated down to a standstill while maintaining a defined distance from a target object, at least until reaching the standstill, a nominal brake torque is defined by the longitudinal dynamic control module for a brake control module. At a defined first time after a detected standstill of the motor vehicle, the longitudinal dynamic control module transmits a transfer signal to the brake control module. Thereupon, independently of the predefinition of a nominal brake torque by the longitudinal dynamic control module, the brake control module alone builds up and/or holds a wheel brake torque in the sense of a parking brake function.
