  • Patent number: 10800407
    Abstract: A driving control device of a vehicle includes a brake device and an ECU. The brake device is configured to apply a braking force to wheels. The ECU is configured to perform driving support control by calculating target deceleration of the vehicle and controlling the brake device such that deceleration of the vehicle reaches the target deceleration, to stop the driving support control when the driving support control is unable to be performed normally, and to determine whether or not a driver is in an abnormal state. The ECU is configured to decelerate the vehicle by controlling the deceleration of the vehicle so as to reach a predetermined value or more, when the driving support control is unable to be performed normally due to factors other than abnormality of the braking device in a situation where a determination that the driver is in an abnormal state is made.
