Abstract
There is provided a controller for a vehicle that can execute, while the vehicle is stationary or moving, control of automatically stopping an engine upon determining that automatic stop conditions are met, and automatically restarting the engine upon determining that automatic restart conditions are met while automatic engine stop is in effect. At a time of first engine restart in one trip, the controller diagnoses whether a system that automatically restarts the engine is normal or abnormal. The automatic stop conditions for in-motion automatic engine stop include automatic stop execution conditions that are set based on a state of the vehicle, and automatic stop permit conditions that are set based on a travel environment. The controller sets the automatic stop permit conditions such that determination criteria are more stringent as a cumulative number of times of in-motion automatic engine stop in one trip is smaller.
