Abstract
In a method for braking a motor vehicle at low speeds in order to avoid a collision with an obstacle in its immediate vicinity, the distance and the relative speed between the vehicle and the obstacle are determined by sensor and are based on the calculation of a necessary braking pressure or a deceleration. The brake pressure is generated at least partially independently of the driver. In order to minimize the reaction time in the case of slow approach to an obstacle in the case where the relative speed falls below a threshold value and the distance falls below a proximity limit, the braking torque is set to a smaller value than the engine torque. In the case where the distance falls below a stop limit, which is smaller than the proximity limit, the braking torque and the engine torque are adjusted in such a way that the braking torque exceeds the engine torque.
