摘要： In a front and rear wheel steering device for vehicle for variably controlling the steering angle ratio of rear wheels relative to the steering angle of front wheels according to a certain mathematical function of vehicle speed in such a manner that the rear wheels are steered in opposite phase relationship in a low speed range and in same phase relationship in a high speed range, by providing a selection means for manually selecting a special mathematical function for an extremely low speed range which will cause a same phase relationship at an extremely low speed and a smooth transition to the certain mathematical function, parking the car along a curbstone and changing the lateral position of the vehicle in a limited space are simplified since the rear part of the vehicle will not swing laterally. Since such a manual setting is not suitable for low to medium speed range, a means for automatically releasing the manual selection may be advantageously provided to the system to the end of reducing the burden on the driver.
