Steer-by-wire systems and methods providing tire force buildup compensation
Abstract:
A steer-by-wire system and method for a vehicle, including and utilizing: a steering wheel system including a steering wheel, an angle sensor or mechanism coupled or applied to the steering wheel and for determining an angular magnitude of the steering wheel and provide a corresponding control signal, and an angular rate sensor or mechanism coupled or applied to the steering wheel and for determining an angular rate of the steering wheel and provide a corresponding control signal offset; and a steering actuator system including a wheel angle actuator coupled to one or more wheels of the vehicle and for receiving the collective control signal and control signal offset and turning the wheels in response. The steering wheel system further includes an angular rate filter/tuner for receiving an angular rate input from the angular rate sensor or mechanism and deriving an angular offset output corresponding to the control signal offset.
