A method for controlling a power steering system utilizes a vehicle having a motor, a controller coupled to the motor, and a steering assembly. The method includes detecting a steering rate using the controller. A base level steering damping is computed using the steering rate. At least one approximate vehicle acceleration is determined. A steering torque of the steering assembly is sensed through a torque sensor configured to sense the steering torque of the steering assembly. Moreover, a user torque is determined using the torque sensor. A damping boost is computed using the user torque and the at least one approximate vehicle acceleration. A final steering damping gain is determined using the base level steering damping and the damping boost. The final steering damping gain is applied to the steering assembly to minimize unwanted feedback to the steering assembly.

Power steering system and a method of operating same

A snowmobile having enhanced steering control has driving control system including an electrically actuated device coupled to a steering system having a user operated steering element with the device applying torque to the steering system, a throttle, a plurality of sensors including a torque sensor and at least one additional sensor to generate terrain condition data and operational data, and at least one controller coupled to the device and the sensors. The at least one controller selects a terrain condition mode using the generated terrain condition and generated operational data, determines the torque to apply responsive to the angle and speed of rotation of user operated steering element, and operates the electrically actuated device to apply the torque to the steering system, with the torque being applied only by the electrically actuated device.
