Abstract
An engine start control system includes a key transponder, a steering lock, a driver authorizer, an engine starting switch, a pre-driving operation detector, a first and second steering lock controllers and an engine start controller. The key transponder stores a slave ID code and transmits the slave ID code at a request. The driver authorizer stores a master ID code and determines whether the slave ID code corresponds to the master user ID code. The pre-driving operation detector detects a driver's preparatory operation to start the engine. The first steering lock controller permits the steering lock to be unlocked when the driver authorizer determines that the slave ID code corresponds to the master ID code. The second steering lock controller unlocks the steering lock when the pre-driving operation detector detects the driver's preparatory operation. The engine start controller permits the engine to be started when the steering lock is unlocked.
