Disclosed is a vehicle control apparatus that can concurrently achieve an improved drivability and an excellent restart performance of an internal combustion engine. The vehicle control apparatus includes an eco-run system that automatically stops the engine when an automatic stop condition is established and restarts the engine when a restart condition is established, a throttle motor that opens and closes a throttle valve adjusting air amount to be sucked into the engine, and a vehicle speed sensor that detects the vehicle speed. The vehicle control apparatus is adapted to control the throttle motor to enlarge the throttle valve opening degree in response to the higher vehicle speed, according to the vehicle speed information from the vehicle speed sensor (Step S3 to Step S7), when the engine is automatically stopped while the vehicle is travelling (Step S2).
