Abstract: A vehicle braking control apparatus includes a controller and a determiner. The controller is configured to switch between a braking-force generating control and a braking-force release control. The controller causes a braking device mounted on a vehicle to generate a braking force in the braking-force generating control and causes the braking device to release the generated braking force in the braking-force release control. The determiner is configured to determine whether an unstable-behavior with rotation around a rotation axis along a vertical direction occurs or not in the vehicle based on a determination-value determined by a state occurred in the vehicle and a state of a road surface with which wheels of the vehicle are in contact. The controller causes the braking device to generate the braking force by executing the braking-force generating control when the determiner determines that the unstable-behavior occurs.

Abstract: A vehicle brake system, including: a first-braking-force control mechanism configured to control a first braking force, a second-braking-force control mechanism configured to control a second braking force, an abnormal-state detecting device configured to detect whether the first-braking-force control mechanism is in an abnormal state, a pseudo-abnormal-state detecting device configured to detect whether the first-braking-force control mechanism is in a pseudo abnormal state in which the first-braking-force control mechanism is suspected to be in the abnormal state, and a controller including a pseudo abnormal state controller configured to control the second-braking-force control mechanism in an operating state of the first-braking-force control mechanism so as to control the second braking force when the pseudo-abnormal-state detecting device detects that the first-braking-force control mechanism is in the pseudo abnormal state.

Abstract: A vehicle brake system includes: a brake device configured to apply a braking force to a wheel; and a controller configured to cause the brake device to perform an ABS operation when a slip ratio of the wheel exceeds a threshold. The ABS operation includes a decrease mode in which the braking force is decreased and an increase mode in which the braking force is increased to restore the braking force after the decrease mode. The controller determines a final target braking force that should be attained at an end time point of the ABS operation based on the braking force at a start time point of the ABS operation and determines a cycle time of the ABS operation based on a condition of a road surface on which the vehicle travels. The cycle time is a length of time in which the ABS operation is performed.
