Title:
REAR-WHEEL STEERING CONTROLLER
Document Type and Number:
Japanese Patent JPH01282073
Kind Code:
A
Abstract:
PURPOSE:To make accurate rear-wheel steering performable all the time by compensating a map concerned in comformity with a deviation between the actual operating force being inputted into a power steering actuator and the setting value of operating force being found out of the specified map on the basis of a running state. CONSTITUTION:In a controller 18 which inputs each output signal of a steering angle sensor 15 as a running state detecting means and a car speed sensor 16, a rear-wheel steering angle value conformed to a running state of a vehicle is operated, while steerage operating force corresponding to the operated result is set by retrieving a specified map. Then, an electromagnetic proportional pressure control valve 11 is controlled by this steerage operating force (setting value) set hereat, feed and discharge of pressure oil to a power cylinder 1 is controlled, thereby having rear wheels subjected to power steering. At this time, actual operating force being inputted into this power cylinder 1 is detected by hydraulic sensors 25A, 25B, and the said map is made so as to be compensated according to a deviation between the detected result and the said setting value.
