PURPOSE:To hole the proper car height and attitude of a car body even when turning by providing a roll decision means and a means for receiving a signal from the roll decision means to control the car height regulation speed in switching controller for car height regulation valve. CONSTITUTION:The wheel 2 is supported rotatably by a supporting member 3 the upper end section 3b of which is coupled through a hydraulic actuator for regulating the car height or a strut 5 to the body 1. A controller 27 will receive a target car height signal S0 from a manual switch 28 and a car height signal S1 from a car height sensor 29 to execute opening control of a levelling valve 24 thus to control pressure oil supply to the strut 5 and to regulate the car height. Here, a steering angle signal S3 from a steering angle sensor 30 and a car speed signal S4 from a car speed sensor 31 are fed to the controller 27 to decide the roll condition. If the roll is high, it is controlled to lower the car height regulating speed. |
