When a collision between a vehicle (10) and a physical object is detected, a notification control unit (50) transmits a notification command to a notification device (28). Upon receiving the notification command, the notification device (28) notifies an external emergency notification center (14). While the notification device (28) is notifying the emergency notification center (14), a brake control unit (52) maintains the actuated state of a brake device (30) and stops the vehicle (10). This configuration makes it possible to prevent any increase in accidents after a vehicle collision, and to prevent the driver from escaping.
