Suspension device of car

Abstract

Abstract PURPOSE:To obtain the steering stability and soft drive comfortableness by increasing the attenuation rate when the output of a vibration sensor continues at a predetermined value or more for a preset time or longer in a suspension device having a variable-attenuation shock absorber and a variable-spring constant spring. CONSTITUTION:The vibration of a car body 4 detected by a car height sensor 3 and an acceleration sensor 2 is inputted to a control unit 1. In the control unit 1, when the sensor output is a predetermined value or more, the duration of a time pulse is judged, and if the duration is larger than a judgment value, a signal is outputted so as to transfer the attenuation rate of a shock absorber 5 and the spring constant of an air spring 9 to larger values. Thereby, the steering stability and soft drive comfortableness can be secured.
