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 vehicle control apparatus is provided with: a calculator configured, in the deflection control, (i) to calculate a target yaw rate so that the subject vehicle drives on a target track by the deflection control, and (ii) to calculate a target yaw moment by dividing the calculated target yaw rate by a coefficient based on a velocity of the subject vehicle; and a controller configured to control a braking force of each wheel so that the target yaw moment is applied to the subject vehicle.

Abstract: A lane departure preventing device includes at least one electronic control unit. The at least one electronic control unit is configured to: when there is a likelihood that a vehicle will depart from a traveling lane, calculate a prevention yaw moment, and control a brake actuator such that the prevention yaw moment is applied to the vehicle; acquire a lateral acceleration; determine whether the lateral acceleration is greater than an ideal value by a predetermined value; control the brake actuator such that the braking force matches a target braking force required to apply the prevention yaw moment to the vehicle, when the lateral acceleration is not greater than the ideal value by the predetermined value; and control the brake actuator such that the braking force is less than the target braking force, when the lateral acceleration is greater than the ideal value by the predetermined value.

Abstract: A vehicle control apparatus includes an electronic control device that controls an internal combustion engine such that a response delay of the internal combustion engine at the time of acceleration is restrained for a predetermined time period from the time point at which an acceleration demand of a driver of a vehicle is estimated when the acceleration demand is estimated while the vehicle is travelling using a driving force from the internal combustion engine.

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.
