A control system for a vehicle having an electronically actuated drive train includes a coordination level which is assigned to a system control device, and in which setpoint values are generated from state variables (ZG) of the vehicle and from driver's requests. Actuation signals for actuating actuators are generated from the latter. An execution level, which is subordinate to the coordination level, has actuators for executing the actuation signals. An axle electronic module for activating at least one brake actuator which is assigned to the chassis is arranged in the region of the steerable vehicle axle. The axle electronic module is connected to the coordination level in order to receive transmittal setpoint values, and determines actuation signals for actuating the respective axle actuator from the setpoint values. The axle electronic module is connected to an electronically actuated steering system for transmitting the actuation signals.

Control system for a vehicle

A test device for vehicles has a wheel rotation speed sensor which is sensitive to magnetic fields. The test device, having a wheel rotation simulation device, contains a sensor stimulating magnet coil, which can be positioned in the magnetic field region of the sensor such that a magnetic field coupling is provided. A control unit, drives this magnet coil with an AC voltage at a frequency which determines the wheel rotation speed. This allows the performance of functional tests of components which are sensitive to wheel rotation speed while keeping the wheels stationary. In addition, a compact roller unit, which is preferably transportable, is provided in order to carry out actual wheel rotations in order to make it possible to test further components, such as the brake system or electronic transmission control. Consequently, component tests which are sensitive to wheel rotation speed can be carried out at the production location and in workshops in a manner which is flexible and optimized with respect to time and cost.
