Abstract
Driving support ECU outputs an instruction to retract a seatbelt to a seatbelt retracting ECU when a driver of a vehicle is determined to be in an abnormal state where the driver loses an ability to drive the vehicle. Thereby, an upper body of the driver in a weak state is pulled strongly toward a backrest side of a seat. As a result, the driver's upper body is prevented from falling and covering a steering wheel, and LKA (traffic lane keeping control) can be performed properly. The driving support ECU decelerates the vehicle at a target deceleration a to stop the vehicle after outputting the instruction to retract the seatbelt.
