A method and apparatus for triggering automatic emergency braking in a vehicle, such as a truck, provides an assistance function for avoiding or mitigating the effects of a rear end collision with a vehicle traveling ahead. A driver warning is triggered if a predefined warning condition requires that an automatic emergency braking process is triggered, but only after the expiration of a predefined warning time period, in order to avoid the vehicle having a rear end collision with the vehicle traveling ahead.

A single processor system features independent multiple watchdog units allocated to a processor unit of the system, the watchdog units operable to monitor for system faults and, upon detecting a fault, further operative to place the processor system into a predetermined fault reaction state. The multiple watchdog units are each provided with respective different watchdog calls which are output to the processor unit depending upon program execution.

A hydraulic power steering system for non-tracked vehicles, particularly motor vehicles, has a steering adjustment of the steered vehicle wheels which takes place of a hydraulic actuating assembly which can be connected by a change-over valve with one respectively of two or several hydraulic circuits. In normal operation, the circuits operate in parallel and functionally in the same direction so that, in the event of a disturbance, a change-over can take place to another hydraulic circuit without any interruption. For controlling the actuating assembly, each hydraulic circuit comprises a servo valve which is operated as a function of a desired-actual value comparison of the steering angle by a control and automatic control device, which is connected with an actual steering angle value generator operated by the steered vehicle wheels and a desired steering angle value generator controlled by way of the steering handle operated on the driver side.
