Abstract: The present disclosure relates to a braking control device that executes an anti-skid control for reducing a braking force when a difference between a target deceleration and an actual deceleration of a vehicle is greater than or equal to a reference value in a braking state in which the braking force is applied to a wheel according to an increase in the target deceleration of the vehicle, the braking control device including a control unit that executes a specific control for reducing an intervention degree of the anti-skid control as a response delay of the actual deceleration with respect to the increase in the target deceleration in the braking state becomes larger.

Abstract: A brake ECU sets target slippage degrees of three wheels other than the front outer wheel to the slippage degree of the front outer wheel and feedback-controls the braking forces of the three wheels such that the actual slippage degrees of the three wheels approach the target slippage degrees. The brake ECU computes a correction amount for the slip ratio deviation of the front inner wheel such that the slip ratio deviation becomes zero. The brake ECU multiplies the correction amount for the slip ratio deviation by a load ratio and uses the resultant value as a correction amount for the slip ratio deviation of the rear inner wheel. The brake ECU corrects the slip ratio deviation by using the computed correction amount.

Abstract: Provided is a brake control apparatus configured to: set a target slip degree of each of three wheels other than an outer front wheel to a slip degree of the outer front wheel; perform feedback control so that an actual slip degree of each of the three wheels becomes close to the target slip degree; and decrease a feedback control amount of a wheel which is to be controlled to increase an anti-spin yaw moment when an understeer suppression condition is satisfied.
