Abstract: The present disclosure relates to motor vehicles. The teachings thereof may be embodied in the operation and control of an externally excited electrical generator in an on-board electrical system of a motor vehicle. An example method may include: setting the excitation voltage within the scope of regulating an actual output voltage of the generator at a predetermined setpoint output voltage of the generator; evaluating load requirements of at least one peak load consumer supplied from the on-board electrical system; identifying exceptional situations based on the load requirements; and in the event of an exceptional situation, setting an associated temporary excitation output voltage of the generator.

Abstract: A method for conveying a metered hydraulic volume in a vehicle braking system by an electrically driven motor pump assembly, wherein a mechanical pump of the motor pump assembly is driven by an electric motor of the motor pump assembly. A rising motor voltage ramp is applied to the electric motor, a motor current being detected, and a conveying mode of the motor pump assembly starting as soon as a motor torque generated by the motor current exceeds a total of drag torque, breakaway torque and friction torque of the motor pump assembly. The motor current reduces when the conveying mode starts. The method is characterized in that, when a reduction in the motor current is detected after a specified time interval has elapsed, a motor voltage is reduced to a value which ends the conveying mode. The invention further relates to a vehicle braking system.

Abstract: An electronic compass has a compass housing. An electronic magnetic field sensor is disposed in a fixed position relative to the compass housing. A magnet is rotatably mounted relative to the magnetic field sensor and independently aligned with a terrestrial magnetic field. The magnet has a magnetic field with a magnetic field direction and the electronic magnetic field sensor is located within a range of influence of the magnetic field. The electronic magnetic field sensor has a first magnetoresistor with a first fixed reference axis and an electric resistance of the first magnetoresistor is a function of a first angle of rotation between the fixed first reference axis and the direction of the magnetic field. The electronic magnetic field sensor defines a first differential bridge circuit and the first magnetoresistor is disposed in the first differential bridge circuit which during operation of the compass, supplies an output voltage dependent on the first angle of rotation.
