ABSTRACT:
A system and a method for dynamically determining a lateral acceleration 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 lateral acceleration, which can then be used to determine a correction factor for the measured lateral acceleration signal. This correction factor is proportional to the erroneous component of the lateral acceleration signal. Together, measured operating state and the correction signal are used to obtain a compensated operating state signal. This is particularly useful for reducing the errors attributable to sensor drift and DC offset in measured signals.
