Abstract
A method of controlling a vehicle engine involves determining a predetermined start operation, which is usually performed by a driver when the driver starts a parked vehicle, and that is not exclusively performed for starting the vehicle engine, verifying a code with a portable device after determining the predetermined start operation, and starting an engine automatically after successfully verifying the code. An engine control device has a start determining mechanism for determining a predetermined start operation, which is usually performed by a driver when the driver starts a parked vehicle, and that is not exclusively performed for starting a vehicle engine, a verifying mechanism for verifying a code with a portable device after determining the predetermined start operation, and a starting mechanism for controlling an automatic engine start after successfully verifying the code.
