Vehicle stability regulating system for land vehicles, with a yaw rate sensor (GRS) which during operation delivers a first output signal (GR) representative of the yaw rate of the vehicle and a second output signal (Temp) representative of the operating or ambient temperature of the yaw rate sensor (GRS), and an additional sensor arrangement (SENS), which delivers a third output signal (0-GR) representing a non-yawing state of the vehicle, at least within a predetermined range of tolerance, wherein the first, the second and the third output signal are fed into an electronic control unit (ECU), and wherein the electronic control unit (ECU) comprises a computer unit (CPU) and at least one writable data memory (RAM) and a control program memory (ROM), which is connected to the computer unit, wherein a control program stored in the control program memory controls the computer unit so that in a learning mode the computer unit determines a temperature-related zero offset value from the first output signal in accordance with the second output signal and stores it in the data memory, and wherein in an operating mode the computer unit reads a temperature-related zero offset value out of the data memory, taking account of the third output signal or the second output signal, and relates it to the first output signal in order to generate an activating signal for intervening in the road behavior of the vehicle.

Vehicle stability regulating system

An anti-lock brake control system comprises at least two micro-computers and at least two input/output circuits which monitor one another as well as functions of other components of the anti-lock brake control system. If faulty voltages appear within the anti-lock brake control system or if false values in transmitted signals occur, the anti-lock brake control system will be dependably shut down. By integrating a plurality of monitoring functions in the input/output circuits as well as by building redundancies into the anti-lock brake control system, a high level of safety is achieved, in spite of the small number of necessary components and the small production cost associated therewith.
