Abstract:
1. A device for securing a standstill of a motor vehicle, comprising: a distance-related longitudinal dynamic control module by which the motor vehicle is capable of being decelerated down to the standstill while maintaining a defined distance from a target object; a brake control module; wherein at least until reaching the standstill, a nominal brake torque is defined by the longitudinal dynamic control module for the brake control module; wherein at a defined first time after the standstill of the motor vehicle is detected, the longitudinal dynamic control module transmits a transfer signal to the brake control module, whereupon the brake control module alone effects a wheel brake torque in a manner of a parking brake function independently of a predefinition of the nominal brake torque by the longitudinal dynamic control module; wherein at a defined second time after a start command, the longitudinal dynamic control module again defines, by itself, for the brake control module, a nominal brake torque, starting at an actual brake torque on hand at this time period, for decreasing the wheel brake torque, and wherein the defined first time after the standstill of the motor vehicle is detected is defined upon reaching a safety-nominal brake torque, set by the brake control module through predefinition of the longitudinal dynamic control module after the detected standstill.
