MOTION CONTROL SYSTEM FOR VEHICLE

摘要

A motion control system is applied to a vehicle, which has front wheel side suspensions (FS) with an anti-dive geometry and rear wheel side suspensions (RS) with an anti-lift geometry. A degree of an anti-lift effect of the anti-lift geometry is larger than a degree of an anti-dive effect of the anti-dive geometry. Normally, a controller (50) controls a hydraulic unit (30) such that a brake force distribution between front wheels (FL, FR) and rear wheels (RL, RR) during a braking-period is adjusted to a basic distribution. In contrast, in a state where abrupt application of brakes is started, the controller (50) controls the hydraulic unit (30) such that the brake force distribution is adjusted to a first distribution, at which a brake force respectively applied to the rear wheels is larger than that of the basic distribution only for a predetermined short time period upon starting of the application of the brakes.
