Abstract: A vehicle control device includes an automatic driving control device configured to execute automatic driving control on a vehicle, and an anti-lock braking system configured to control a longitudinal slip ratio of wheels of the vehicle to be equal to or smaller than a threshold during braking of the vehicle. The automatic driving control to be executed by the automatic driving control device includes braking force control for changing a braking force to be applied to the wheels of the vehicle depending on a target deceleration set without being based on a deceleration request by a driver. The automatic driving control device is configured to, when a failure of the anti-lock braking system is detected during execution of the automatic driving control on the vehicle, set the target deceleration in the braking force control to a value equal to or smaller than an upper limit deceleration value.

Abstract: A slope-descending speed control device 10 for a vehicle configured to control a vehicle deceleration so that an actual vehicle speed conforms to a target vehicle speed in accordance with a target deceleration Gxbt of a PID feedback control executed in accordance with a difference between a target vehicle speed Vxt and an actual vehicle speed Vx. In a situation where an actual vehicle speed is higher than a target vehicle speed, with a component in a hill-descending direction of gravitational acceleration of the vehicle at a time point when a condition for starting a slope-descending speed control is satisfied being a reference gravitational acceleration Gxd0, when a difference between a component Gxd in a hill-descending direction of gravitational acceleration and the reference gravitational acceleration Gxd0 is between upper and lower reference values, a target deceleration Gxbti of the integral term is not integrated to restrain its increase.

Abstract: Provided is a control apparatus for a vehicle configured to perform driving support control when a driving support operation state is an on state, the control apparatus being further configured to, in a case where the driving support operation state is the on state and a driving operation switching request for changing the driving support operation state to an off state is issued, calculate a target speed at a driving operation switching time point at which the driving support operation state is changed from the on state to the off state, and perform deceleration control for decelerating the vehicle such that a speed of the vehicle matches the target speed at the driving operation switching time point.
