Abstract
Provided are an apparatus and a method for starting automobile engine by a radio communication between an automobile smart key and a smart key electronic control unit (ECU). According to this invention, it is decided whether or not a transmission lever position signal and a break pedal signal are ON. The smart key ECU requests a smart key for a smart key ID when both signals are ON, and receives the smart key ID from the smart key. Then the smart key ECU performs the verification of the smart key using the received smart key ID and turns the starting control relay ON when the smart key is verified. Additionally, when the ignition switch is turned ON within the prescribed time after the starting control relay is turned ON, the smart key ECU supplies the electric power from the ignition switch to the starting motor, thus starting the automobile engine.
