Relative vehicle platform having synchronized adaptive offset calibration for lateral accelerometer and steering angle sensor

An automotive vehicle comprising a dynamic control system for controlling at least one characteristic of vehicle dynamics, the control system comprising:

• a steering angle sensor providing a steering angle signal measurement;
• a first calibration filter for calibrating the steering angle signal measurement to a compensated steering angle signal measurement;
• a lateral acceleration sensor providing a lateral acceleration signal;
• a second calibration filter for calibrating the lateral acceleration signal measurement to a compensated lateral acceleration signal measurement;
• the first and second calibration filters having identical synchronization;
• a yaw rate sensor, including compensation, providing a compensated yaw rate signal measurement;
• a processor a) for the compensated yaw rate signal measurement and the compensated lateral acceleration signal measurement to derive a signal measurement of road bank angle disturbance not compensated for in the compensated steering angle signal measurement, b) providing the compensated steering angle signal measurement and the signal measurement of road bank angle disturbance not compensated for in the compensated steering angle signal to adjust the control action of the vehicle dynamic control system.
