外文摘要：A lock system can be provided at each rear wheel assembly of a four wheel steering system to physically lock the rear wheel assemblies in a fixed direction to safely prevent rear wheel steering when such feature is undesirable. The lock system can use an electronically controlled actuator to hydraulically drive or retract a lock cylinder to lock or unlock the rear wheel assemblies, respectively. Sensors can be used to detect whether the lock cylinders are driven or retracted by their respective actuators, so that a controller monitoring the sensors can determine whether four wheel steering is enabled or disabled.
