ABSTRACT:
A "normal mode" allows a hijacker to drive away but disables the vehicle after a short delay. An optional "valet mode" allows others, e.g. parking attendants and mechanics, a limited driving period that when exceeded causes vehicle shut-down that cannot be overcome without actuating a hidden switch. One embodiment has both modes and includes: a switch for arming the system in the normal mode; an element, responsive to a hijacking event, e.g. a door opening, when the system is armed in the normal mode, for measuring a "hijack delay", preferably three minutes; an element for producing a first signal at the expiration of the hijack delay; an element responsive to said first signal for disabling the vehicle; an element for arming the system in the valet mode; a valet mode element for preventing disablement of the vehicle in response to the first signal; an element for sensing vehicle motion and producing a second signal in response thereto; a valet mode element responsive to the second signal for measuring a "valet delay"; an element for producing a third signal at the expiration the valet delay, the valet delay measuring element being disabled whenever the second signal is not extant; and an element responsive to the third signal for disabling the vehicle. This embodiment can also include an element responsive to the second signal for preventing disablement of the vehicle in either mode until the second signal is no longer extant.
