Shock absorber control device

Abstract

Abstract PURPOSE:To easily further accurately control damping power by estimating the relative displacement between a car body and a wheel being based on the damping power of a shock absorber further deciding a road surface condition being based on a period of the relative displacement while switching the damping power in accordance with the road surface condition. CONSTITUTION:Each damping power of a number of shock absorbers 6 (6a-6d), provided in a vehicle, is detected by a number of load sensors 1a-1d respectively serving as a damping power detecting means 1. Each detected damping power is input respectively to a microcomputer 4 equipped with a CPU41 and other each equipment 42-46. Here being based on each damping power, the relative displacement between a car body and a wheel is estimated. While of the estimated relative displacements, in accordance with a period of the relative displacement larger than the predetermined displacement, a road surface conditioner for the vehicle running is decided. Thereafter, in accordance with the decided road surface condition, the damping power of each shock absorber 6a-6d is switched by a driving circuit 5.
