Abstract
A vehicle antitheft system capable of safely stopping a vehicle after being stolen. The vehicle antitheft system monitors the state of the vehicle by means of an antitheft control apparatus using a shock sensor, a door sensor, and others which are installed in the vehicle. If an illegal act against the vehicle is detected, an alarm is set off to the outside by means of a siren, a lamp, and the like. When a speed reduction command is received from a hand-held controller outside the vehicle, an injector control relay is controlled so as to stop an operation signal to an injector, and thereby to stop the fuel supply to the engine. Thus, the vehicle is forcibly slowed down to travel at a predetermined speed limit (for example, 30 km/hr) or lower.
