An electrohydraulic brake system, comprising a brake master cylinder. A pressure generating device for actuating wheel brakes and an additional brake actuator may both be activated electronically. In a normal mode of operation, an open- and closed-loop control unit detects a braking demand based on the actuation of a brake pedal by the driver and activates the pressure generating device to build up braking torque at the wheel brakes. If the pressure generating device is not activated, the driver gains direct access to the wheel brakes and the control unit activates the additional brake actuator to build up braking torque. In the fallback mode, when a predetermined pedal travel threshold value is reached, the control loop activates the additional brake actuator to build up braking torque. In the event of a succession of brake pedal actuations by the driver, the pedal travel threshold value is increased at least once.

Brake system and method for operating a brake system

Method and control device for determining a steering angle of a motor vehicle, wherein a theoretical steering angle is calculated by a vehicle model and a measured steering angle is determined with a steering angle sensor, and the difference between the measured and theoretical steering angles is determined, wherein at least one data record including a number of successive measured values is acquired, and a correction constant for the measured steering angle is determined from the mean value of the differences between the theoretical steering angle and the measured steering angle. According to the invention, a confidence level, which changes incrementally between successive data records, is calculated by travel conditions present during the acquisition of the data record and/or an analysis of the data record.

Determination of steering angle for a motor vehicle

In a method for determining a steering angle for a vehicle, a steering angle is determined using a single-track model of the vehicle, wherein the steering angle is corrected only if the difference between the derivative of a measured steering lock angle and the derivative of a calculated steering lock angle is below a threshold value. Otherwise the measurement is repeated.
