Abstract
Driving support ECU determines that a driver is in an abnormal state when a state where a steering amount correlation value which changes when a steering wheel SW of a vehicle is operated does not change continues over more than or equal to an abnormality determination threshold time. When the driver is determined to be in the abnormal state, the ECU decelerates the vehicle, makes a hazard lamp blink and invalidates an acceleration request based on a change in an operation amount of an accelerator pedal. The ECU terminates decelerating of the vehicle and permits the acceleration override when a specific driving operation (an operation that the accelerator pedal changes from an operating state to a non-operating state and then again changes to the operating state within a predetermined threshold time) is determined to have occurred after the driver has been determined to be in the abnormal state.
