Brake control system for four-wheel drive vehicle.

摘要

A brake control system for a vehicle provided with a four-wheel drive mechanism and an antiskid brake system for controlling the braking effort upon application of the brakes to prevent locking of the wheels comprises a brake application sensor (11, 11a, 17) for detecting application of the brakes over a predetermined level to such a degree that can lead to locking of the wheels, and a releasing mechanism (12, 13) which releases the driving connection between the front wheel driving system (2,7) and the rear wheel driving system (5, 8) of the four-wheel drive mechanism when the brake application sensor (11, 11a, 17) detects application of the brakes over the predetermined level.
