Ground clearance adjuster for vehicle

Abstract

Abstract PURPOSE:To check the rolling of a vehicle positively by providing a means which operates the deviation between an actual ground clearance and a reference one, thereby making an adjustment control of the deviation to a specified range depending on operating conditions. CONSTITUTION:Signals from ground clearance sensors 87 through 90 provided to each corresponding position of actuators, are outputted to an electronic control device 102 for operating the deviation from a reference ground clearance. On the other hand, based on signals from a vehicle speed sensor 95 and a steering angular velocity sensor 96, a judgement is made as to whether a vehicle is in any of a stop condition, a running condition, on a rolling condition for controlling the feeding and discharging of oil to each of actuators with the drive duty corresponding to each of the conditions so as to control the deviation with a corresponding range. This constitution adjusts the ground clearance properly to a target ground clearance range for the stop or the running condition, and also checks the rolling of the vehicle positively for a curved running condition.
