THEFT DETERRENT DEVICE AND TRANSPORTING DEVICE

摘要

A microcomputer of a theft deterrent device authenticates a user by using an ID reading device with an engine running. If the authentication fails, the microcomputer detects the speed of the engine. If the speed of the engine is higher than a predetermined safe stop speed, the microcomputer controls ignition of the engine or controls fuel injection of the engine to gradually reduce the engine speed to a level lower than or equal to the safe stop speed. When the engine speed reaches the level lower than or equal to the safe stop speed, the microcomputer stops the engine.
