System and method to select a steer mode
Abstract:
The present disclosure is related to a system to control switching between a two wheel steer mode and a four wheel steer mode. The system may have a sensor device that monitors an operational value indicative of vehicle speed and emits an operational signal corresponding to the operational value. A controller is provided in the system, which receives the operational signal and selects between the two wheel steer mode and the four wheel steer mode based on the operational signal.
