Abstract
The present invention makes it possible to appropriately grasp a stop cause when a vehicle stops. An ECU, which controls a vehicle including wheels and a vehicle body connected to the wheels includes: a wheel stop detection unitthat detects a stop of the wheels; a vehicle body stop detection unitthat detects a stop of the vehicle body; and a stop cause determination unitthat determines a stop cause of the vehicle based on a stop timing of the wheels detected by the wheel stop detection unitand a stop timing of the vehicle body detected by the vehicle body stop detection unit. The stop cause determination unitmay determine that the stop cause is contact of the vehicle body with an obstacle when the stop timing of the vehicle body is earlier than the stop timing of the wheels.
