Abstract
A method for preventing a stationary vehicle (12) from rolling away, wherein a holding mode can be activated by actuating a brake pedal (18), wherein at least one wheel brake device (14) of the vehicle (12) is controlled in the holding mode in order to generate a braking force in such a way that the vehicle (12) is held in the stationary state, and wherein a physical variable which represents the actuation of the brake pedal is detected, wherein the holding mode is activated if a gradient of the physical variable exceeds an activation threshold value.
Claims14
A method for preventing a stationary vehicle from rolling away, comprising the steps of actuating a brake pedal to bring the vehicle to a stationary state, and afterward actuating the brake pedal again to activate a holding mode, wherein at least one wheel brake device of the vehicle is activated in the holding mode in order to generate a braking force in such a way that the vehicle is held in the stationary state, and detecting at least one physical variable which represents the subsequent actuation of the brake pedal, wherein the holding mode is activated if a gradient of at least one detected physical variable exceeds an activation threshold value.
A device for preventing a stationary vehicle from rolling away, having a control device which is designed to activate a holding mode as a result of the actuation of a brake pedal when the vehicle is stationary, wherein the control unit is designed to control a wheel brake device of the vehicle in the holding mode in order to generate a braking force, in such a way that the vehicle is held in the stationary state, and having a sensor which is designed to detect a physical variable which represents the actuation of the brake pedal, wherein the control device is designed to activate the holding mode if a gradient of the physical variable exceeds an activation threshold value.
