System and method for determining desired yaw rate and lateral velocity for use in a vehicle dynamic control system

摘要

A control system ( 18 ) and method for an automotive vehicle ( 10 ) includes a lateral acceleration sensor ( 32 ) for generating a lateral acceleration signal, a yaw rate sensor ( 28 ) for generating a yaw rate signal, and a safety system. The safety system ( 44 ) and the sensors are coupled to a controller ( 26 ). The controller ( 26 ) determines a front lateral tire force and a rear lateral tire force from the vehicle yaw rate signal and the vehicle lateral acceleration signal; determines a calculated lateral velocity from the front lateral tire force, the rear lateral tire force, and a bank angle; determines a calculated yaw rate from the front lateral tire force and the rear lateral tire force; and controls the safety system in response to the calculated lateral velocity and the calculated yaw rate.
