Abstract
When a driving support electronic control unit (DSECU) determines that a driver of a vehicle is in an abnormal state where the driver loses an ability to drive the vehicle, the DSECU starts driving control under the abnormal state to decelerate the vehicle until the vehicle stops and to sound a horn. In this case, the DSECU measures an elapsed time since the horn starts sounding with a horn timer th, and sets a sounding pattern corresponding to the elapsed time measured. This sounding pattern is set in such a manner that a ratio of a sounding time of the horn per unit time decreases as the elapsed time since the horn starts sounding become longer. Thereby, it becomes possible to properly notify that the driver is in the abnormal state using the horn.
