Abstract: A braking control apparatus performs right and left wheel independent control to approach a slip rate of a rear-right wheel and a rear-left wheel to a target slip rate as an average of slip rates of a front-right wheel and a front-left wheel. In a high-speed range, right and left wheel independent control is started when a deceleration is equal to or larger than a start value that is smaller than a start value used in a low-speed range. In right and left wheel independent control started in the high-speed range, when there is a demand to increase braking pressures of both the rear-right wheel and the rear-left wheel, the braking pressure of the rear wheel located on the outside during the occurrence of deflection of the vehicle resulting from braking is increased, and the braking pressure of the rear wheel located on the inside is prohibited from increasing.

Abstract: A vehicle includes a regenerative braking device provided on regenerative braking wheels, which are any ones of front wheels and rear wheels, a frictional braking device configured to separately control a frictional braking force applied to each of the front wheels and the rear wheels, and an electronic control unit is configured to, upon detecting a slip state where a wheel speed of the regenerative braking wheels executing regenerative braking is below a slip determination threshold value positioned between a vehicle body speed and an anti-lock brake control operation threshold value, execute a regenerative control process for controlling the regenerative braking device such that the regenerative braking device generates a regenerative braking force that decreases a difference between the wheel speed and the slip determination threshold value.
