Abstract: A brake control system has an electronic control unit such that, when the motor vehicle is at a standstill, an automatic parking brake function can be activated by the control unit. In the presence of an activation condition for the parking brake function, the brake pressure required for this purpose can be determined at least in a manner dependent on the longitudinal inclination and in a manner dependent on an estimated normal force distribution of all of the wheels and/or an estimated capability of all of the wheels to transmit braking and/or drive torque to the underlying surface. Here, the brake pressure can be predefined to be higher the more wheels have a reduced normal force.

Abstract: A method and a corresponding device are provided for preventing an undesired vehicle motion during an automatic switch-off process of a drive machine in a motor vehicle. An automatic switch-off process is initiated by a start-stop apparatus before the standstill is reached if the motor vehicle is braked because of a deceleration request and the speed of the vehicle is less than a specified first speed threshold. A brake pressure of suitable magnitude is caused to be locked-in in the brake system even before the vehicle reaches the standstill if a first signal indicating that the vehicle standstill will soon be reached and a second signal indicating that an inability of the drive machine to operate in a self-sustaining manner will soon be reached are acquired because of an initiated automatic switch-off process of the drive machine.
