  • Publication number: 20200156607
    Abstract: A vehicle braking force control apparatus of the disclosure executes a slip rate reduction control to reduce a slip rate of any of wheels of a vehicle becoming equal to or greater than a predetermined slip rate threshold by automatically changing braking force applied to one or more of the wheels. The apparatus uses a first slip rate threshold as the predetermined slip rate threshold during a normal acceleration-and-deceleration control and a normal steering control. The apparatus uses a second slip rate threshold during a driving assist control. The second slip rate is set to a value smaller than the first slip rate threshold and near and smaller than the slip rate, at which a friction coefficient between the wheel and a surface of a road on which the vehicle moves is maximum.
