An energy absorber for a vehicle is described, which includes a sensor integrated into the energy absorber, which is designed to detect an impact magnitude acting on the energy absorber and to provide information about the impact magnitude. Furthermore, the energy absorber includes at least one setting element, which is designed to set a stiffness of the energy absorber in response to the information about the impact magnitude.

In a method and a device for monitoring a brake system, e.g., a wheel pressure sensor suite of a brake system of a motor vehicle, the fault detection is implemented on the basis of a differential threshold being exceeded by a signal that is representative for the difference of the brake pressures at the individual wheel brakes of a wheel axle. In the process, the differential threshold is set as a function of the averaged rate of increase of the individual pressures at the wheel brakes. Fault detection is carried out on the basis of a model, which takes the instantaneous operating state of the brake system into account.

A servo-assisted steering system for a motor vehicle, in which the steering system includes a steering wheel for presetting a desired steering angle for the wheels of the motor vehicle, a driving-dynamics means for superimposing a correction angle on the steering angle, the correction angle being determined with a view toward increasing the driving stability and/or the driving comfort of the motor vehicle, and a servo drive. To keep the efficiency of the driving-dynamics means nearly constant over the entire road-speed range of the vehicle, the servo drive is implemented as a variable torque assistance system, the degree of torque assistance being dependent on the road speed of the vehicle and on at least one variable of the driving-dynamics means that characterizes the correction angle.
