Event: JSAE Spring Conference
A rear-steel steering system with motor-driven servo control has been developed and implemented in production vehicles. This system is more accurate, more stiff, lighter, and more compact than previous rear-wheel steering systems using hydraulic-control. In terms of the construction, the system uses a motor-driven actuator to steer the rear wheels via highly efficient, nonreversible hypoid gears with a high gear ratio. In production vehicle application, using highly accurate phase-reversal and delay control, the system provides outstanding vehicle performance with excellent stability and response and a better match with the driver's expectations
