Abstract
An improved low cost vehicle yaw rate control that is compensated for road bank angle using readily available information, such as steering angle, vehicle speed, and the speeds of the un-driven vehicle wheels. The control is founded on the recognition that, under linear operating conditions on a banked surface, the difference between the desired yaw rate and the actual or estimated yaw rate yields a yaw rate offset that will compensate for the bank angle, and the product of yaw rate and vehicle speed corresponds substantially to lateral acceleration. The yaw rate offset is used to compensate the yaw control when the steering angle, the yaw rate--vehicle speed product and yaw rate error are indicative of operation on a banked road. The compensation is deactivated when the steering angle, the yaw rate--vehicle speed product and yaw rate error are not indicative of operation on a banked road.
