Claims

[Scope of utility model registration request]

a power transmission system arrangement sensor that outputs arrangement information as to whether the arrangement of the vehicle power transmission system is in a 4WD direct connection state in which the front and rear wheels are directly connected or in a non-4WD direct connection state;
three wheel speed sensors that output wheel speed information of either one of the left and right front wheels and the left and right rear wheels, a brake pressure regulator that regulates the hydraulic pressure of the brake hydraulic system of the vehicle, and the above arrangement. rear wheel speed calculation means for calculating the speed of the other one of the rear wheels based on the information and the wheel speed information, and the brake pressure regulator based on the four wheel speed information when braking in the 4WD direct connection. An anti-skid brake device for a four-wheel drive vehicle, comprising a control means for operating anti-skid control.
