Abstract:
1. A vehicle control system for controlling a vehicle having a body, a pair of front wheels, and a pair of rear wheels, comprising: a body-height adjusting device which adjusts four body heights each of which is defined as a relative-position relationship between corresponding one wheel of the pair of front wheels and the pair of rear wheels, and the body; and a brake-operation-force control device which controls respective operation forces of a pair of front-wheel brakes and a pair of rear-wheel brakes that restrain respective rotations of the pair of front wheels and the pair of rear wheels, wherein the brake-operation-force control device comprises an operation-force lowering portion which controls, in at least a portion of a time duration when the body-height adjusting device adjusts at least one of the four body heights, the respective operation forces of at least one pair of brakes of the pair of front-wheel brakes and the pair of rear-wheel brakes, so that the controlled operation forces are low as compared with said respective operation forces when the body-height adjusting device does not adjust any of the four body heights, and wherein the operation-force lowering portion comprises a body-height-change-amount-dependent operation-force lowering portion which lowers, when an amount of change of said at least one body height caused by the body-height adjusting device has reached a first reference amount, the respective operation forces of said at least one pair of brakes of the pair of front-wheel brakes and the pair of rear-wheel brakes.
