Abstract: A deflection control apparatus is configured to perform a deflection control in which a subject vehicle is deflected by a braking force difference between left and right wheels. The deflection control apparatus is provided with a releaser configured to release the deflection control if a steering operation, which is an operation of deflecting the subject vehicle in a direction opposite to a direction in which the subject vehicle is deflected by the deflection control, is detected during the deflection control. When releasing the deflection control, the releaser is configured to reduce a controlled variable over a predetermined time, which is shorter than a fall time of the controlled variable when the deflection control is ended without being released, and which becomes longer, as the controlled variable increases when the steering operation is detected.

Abstract: A deflection control apparatus is provided with: a determinator configured to determine whether or not a vehicle is about to depart from a driving lane; and a controller programmed to perform a deflection control for controlling a braking apparatus to supply a fluid pressure to at least one of brake mechanisms corresponding to a front wheel and a rear wheel on a side opposite to a departure direction of the vehicle. The controller is programmed to control the braking apparatus to supply the fluid pressure to the brake mechanism that is close to a fluid pressure source, out of the brake mechanisms corresponding to the front wheel and the rear wheel on the opposite side, on condition that a motion state corresponds to a regular-use area of the braking apparatus, if it is determined that the vehicle is about to depart from the driving lane.
