Braking control device of vehicle
In the case that the road surface is determined to have different friction coefficients on the left and right wheels, this braking control device performs antiskid control for adjusting the increase slope of front wheel braking torque on the side with the higher friction coefficient. A steering angle sensor detects the steering angle, and a yaw rate sensor detects the yaw rate. The device calculates a reference turning amount on the basis of the steering angle, calculates an actual turning amount on the basis of the yaw rate, and sets the increase slope on the basis of the deviation between the reference turning amount and the actual turning amount. Also, if this deviation becomes larger, a correction is made such that the set increase slope becomes smaller. Further, if the deviation becomes smaller, a correction is made such that the set increase slope becomes larger.
