Actively controlled suspension system with compensation of delay in phase in control system

摘要

An actively controlled suspension system which can perform precise control of suspension characteristics with satisfactory compensation of phase delay caused in a control system. The actively controlled suspension system which can successfully avoid influence of the shifting of the gravity center of a vehicle body caused by a variation of load on the vehicle. The actively controlled suspension system employs more than one lateral acceleration sensor which are oriented at axially or longitudinally shifted positions to each other. Based on the outputs of respective lateral acceleration sensors, anti- rolling suspension control signals are produced for controlling suspension characteristics of the left- and right-sides of a suspension system.
