摘要
A method for determining road bank angle in a vehicle includes a lateral acceleration sensor (22) that generates a lateral acceleration signal. A yaw rate sensor (18) generates a yaw rate signal. A roll rate sensor (23) generates a yaw rate signal. A controller (14) coupled to the sensors calculates a first roll angle signal in response to the roll rate signal and calculates a second roll angle signal corresponding to a suspension reference roll angle in response to the lateral acceleration signal. The controller calculates a bank angle signal in response to the lateral acceleration signal, the yaw rate signal, the steering wheel signal and the speed signal. The controller sums the first roll angle signal, the second roll angle signal and the bank angle signal to obtain a final roll angle estimate.
