Abstract
A suspension pressure control system applies a pressure which is proportional to a current level supplied to a solenoid of a pressure control valve to a shock absorber associated with a suspension from the valve. A height and a lateral acceleration of a car body as well as a steering angular velocity are detected. A deviation of the height from a target height is calculated. The suspension pressure is adjusted responding to the deviation and a change rate thereof. Also a correction value is calculated on the basis of the lateral acceleration for adjusting the suspension pressure responding to the correction value and a change rate thereof. Proportional coefficients for converting the change rate of the deviation and the change rate of the correction value to pressures to be corrected are corresponding to the steering angular velocity.
