Abstract

The risk of vehicle theft is substantially diminished with an arrangement employs a decoder that is integrally coupled to, or embedded in, one or more operating elements of a vehicle that are controlled with an electrical signal. The decoder is constructed to be responsive to an encoded signal that is generated with a security device, such as a keypad

Claims

1. Apparatus for attachment to a vehicle comprising

an element that is necessary for causing said vehicle to travel in normal operational mode;

and

a decoder embedded in said element that enables normal operation of said element when a preselected coded signal is applied to said decoder, said decoder being embedded in a manner that prevents activation, and normal operation, of said element solely by application of a DC potential to any available lead, or terminal in said vehicle.

2. The apparatus of claim 1 where said decoder enables normal operation of said element in response to application of energy in excess of a preselected amount in a preselected set of frequencies.

3. The apparatus of claim 1 where said decoder enables normal operation of said element in response to a preselected set of digital signals.

4. The apparatus of claim 3 where said decoder enables normal operation of said element in response to a preselected set of digital signals that are repeatedly applied in accord with a preselected schema.

5. The apparatus of claim 1 where said element operates in a degraded mode in the absence of said preselected coded signal, and said degraded mode allows said vehicle to travel, but only at a preselected maximum speed.

6. The apparatus of claim 1 where said element control fuel that is applied to an engine of said vehicle.

7. The apparatus of claim 6 where said element is a fuel valve.

8. The vehicle of claim 6 where said element is a unit that control fuel injection.

9. A vehicle including an engine and various electrical and electromechanical components that control operability of said vehicle, and including a combination of an element and an associated decoder, which combination becomes operative in a normal mode upon application of a coded signal to said decoder, the improvement comprising:

said combination remains inoperative in it normal mode in spite of application of a DC signal to some accessible point, and operation of said element is not-circumvetable by application of a DC signal to some accessible point.

10. The vehicle of claim 9 where said decoder enables said normal operation upon application of energy in excess of a preselected amount in a preselected set of frequencies.

11. The vehicle of claim 9 further comprising at least one additional element-decoder combination, which additional combination becomes operative in a normal mode upon application of a coded signal to said decoder in said additional combination, and said additional combination remains inoperative in its normal operation sense in spite of application of a DC signal to some accessible point in said vehicle, and operation of said element is said additional combination is not-circumvetable by application of a DC signal to some accessible point in said vehicle.
