    摘要: A method for automatically adjusting a vehicle stability enhancement (VSE) system. The VSE system is used in conjunction with a steering system having a plurality of driver-selectable steering modes associated therewith. The method includes configuring a reference model within the VSE system to generate desired vehicle handling aspects, the desired vehicle handling aspects being a function of one or more driver inputs to the steering system. Then, a determination is made as to which of the plurality of driver-selectable steering modes is activated, wherein each of the desired vehicle handling aspects generated is made further dependent upon a specific steering mode selected, and wherein the desired vehicle handling aspects include a desired steady state yaw rate; and the one or more driver inputs includes an effective road wheel position.

    摘要: Disclosed herein in an exemplary embodiment is a method for providing variable assist in an active steering system of a vehicle. The method comprises: receiving an input signal that includes at least one of, a variable ratio command signal, a stability command signal, a hand wheel position signal, a vehicle speed signal indicative of a speed of the vehicle, a signal indicative of an operator selected function, and a signal indicative a vehicle operating mode. The method also comprises: generating an assist command to an assist mechanism responsive to the input signal wherein the assist mechanism is operatively coupled to the differential actuator and a road wheel of the steering system to provide an assist torque responsive to the motion of the output shaft. The active steering system includes a hand wheel operatively coupled to an input of a differential actuator and a motor operatively coupled to the differential actuator. The differential actuator is configured to translate motion of the input into motion of the output shaft, where the motion of the output shaft is further responsive to the motor and wherein the output shaft is coupled to the road wheel of the steering system.

    摘要: A method for collision avoidance using automated braking and steering comprising: determining an actual distance to an obstacle in a path of a vehicle; determining a relative velocity between the obstacle and the vehicle; determining a first distance sufficient to avoid collision by braking only; determining a second distance sufficient to avoid collision by combined braking and steering around the obstacle. The method also includes: applying braking if at least one of, the first distance exceeds the actual distance and the first distance is within a selected threshold of the actual distance. If the actual distance exceeds the second distance and a lane change is permitted, steering control to affect a lane change is applied.
