置。[Claims for Utility Model Registration] Two wheel speed detection means for detecting the wheel speeds of left and right wheels provided on a vehicle, and two wheels that actuate brakes for each of the left and right wheels. two actuators that control the hydraulic pressure of each cylinder, and uniform anti-skid control of the two actuators based on the wheel speed of the wheel with a stronger lock tendency among the left and right wheels during braking. In the anti-skid control device, the anti-skid control device includes anti-skid control means that selectively performs anti-skid control and independent control that independently controls anti-skid on two actuators based on the wheel speed of each wheel. tract, medium μ tract and low μ
road surface μ detection means for detecting whether the road is a high μ road; yawing detection means for detecting that the vehicle has yawed by a predetermined amount or more during braking; and the road surface μ detection means detects a high μ road. The anti-skid control means performs independent control and uniform control regardless of the detection result of the yawing detection means when a low μ road is detected, but when the road surface μ detection means detects a medium μ road. 1. An anti-skid control device comprising control state control means for performing uniform control if the yawing detection means detects yawing, and performing independent control if the yawing detection means does not detect yawing.
