A method to operate a motor vehicle having a number of wheels is described. The method determines a steering angle for an automotive application. A steering angle &#x3b4; is estimated using a yaw rate &#x3c9;, a revolution rate of at least one wheel, a wheelbase L and a characteristic speed of the vehicle vbased on a single-track model. Preferably, the steering angle is calculated using the yaw rate &#x3c9;, the selected gear i, the wheelbase L, the speed v and the characteristic speed of the vehicle vaccording to the formula &#x3b4;=[&#x3c9;*i*L*(1+v/v)]/v. An application, such as adaptive light control during turns, that requires knowledge of the steering angle of the motor vehicle is carried out based on an estimated steering angle.

Determining a steering angle for an automobile application

Determining a brake torque reduction parameter for brake torque reduction in a motor vehicle having a brake holding assist function. The determination including detecting a motion parameter of the motor vehicle and analyzing the detected motion parameter to determine a correction value for a brake torque reduction parameter. Adjusting the brake torque reduction parameter using the correction value determines an optimized brake torque reduction parameter. The optimized brake torque reduction parameter is used as a brake torque reduction parameter of the brake torque reduction.
