Abstract
An apparatus for controlling air pressure of an onboard air support system of a vehicle comprising a pump connected to the air support for supplying or discharging the air to or from the air support, a pressure sensor in association with the air support for detecting the pressure thereof, a memory for storing present pressure values for the air support, a controller for generating pump operation control data on the basis of data derived from the detection output of the pressure sensor and data of the preset pressure value stored in the memory means, and a timer for determining the period during which the pump is to be operated on the basis of control data available from the controller, and producing a control signal supplied to said pump. Upon adjustment of the air pressure of the air support, the air pressure information inputted and stored previously is compared with the current air pressure, wherein the time for which the pump is operated is set in accordance with a difference resulting from the comparison, followed by operation of the pump.
