A judgment unit and a control unit are provided in a vehicle antitheft device.
On the basis of a theft occurrence signal from a security device which can detect
occurrence of theft of a vehicle and GPS signals from a GPS receiver which can
detect positional information of the vehicle, the judgment unit judges whether
the vehicle is near a place such as a police station or not, when vehicle theft
has occurred. When it is concluded that the vehicle is near the place such as the
police station during occurrence of the vehicle theft, the control unit makes control
to stop the vehicle.
