  • Publication number: 20200108810
    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.

  • Publication number: 20200094798
    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.

  • Publication number: 20200062229
    Abstract: A brake device includes a second setting unit that sets a target wheel deceleration of at least one of the wheels to which a target wheel brake force; detection units that detect the actual wheel deceleration of the wheel to which the target wheel deceleration; a first calculation unit that calculates a vehicle deceleration difference which is the difference between the target vehicle deceleration and the actual vehicle deceleration; a second calculation unit which calculates a wheel deceleration difference which is the difference between the target wheel deceleration and the actual wheel deceleration; and a correction unit which corrects, on the basis of the vehicle deceleration difference and the wheel deceleration difference, the target wheel brake force corresponding to at least one of the wheels to which the target wheel brake force is set so that the vehicle deceleration difference becomes smaller.
