Abstract
A system for dynamically determining an operating state of a motor vehicle for input to a controller employed to control dynamics of the motor vehicle includes sensors for measuring predetermined vehicle operating state. The system also includes a device for predicting a value for the predetermined operating state, which can then be used to determine a correction factor for the measured operating state signal. This correction factor is proportional to the erroneous component of the measured vehicle operating state. Together, measured operating state and the correction signal are used to obtain a compensated operating state signal. This is particularly useful for reducing the effects of sensor drift and DC offset.
