Abstract

An automatic starting and electronic detection system for remotely starting a vehicle and scanning the vehicle'"'"'s electrical system components for explosives or to detect malfunctions. The system includes a clock and remote-control receiver and transmitter combination which are electrically connected to the battery and operable to be energized for selectively connecting a current signal from the battery to the balance of the system including the starter circuit of the vehicle. The electronic detection device includes a cascade arrangement of timers for actuating various vehicle lights and accessories, and the vehicle'"'"'s horn, in a predetermined sequence of sufficient duration to give a vehicle operator feedback for each step in the sequence.

Claims

1. An automatic detection system for a vehicle having a battery and a plurality of electrical system components, comprising:

(a) means remote from said vehicle for generating an actuation signal;

(b) means for selectively supplying power to said plurality of electrical system components including vehicle headlights, indicator lights and horn, said supplying means including a plurality of separately actuatable switch means for energizing particular ones of said electrical system components;

(c) sequence control means responsive to said actuation signal for actuating said plurality of switch means in a predetermined sequence; and

(d) means for maintaining at least one of said electrical system components deenergized at any one time during the predetermined sequence,

wherein said sequence control means is operative to automatically sequence entirely through the predetermined sequence in response to said actuation signal,

whereby all of said electrical system components are automatically energized in response to a single actuation signal while the instantaneous current drain from the battery of said vehicle is limited.

2. The automatic detection system of claim 1 wherein said remote means includes transmitter means for transmitting said actuation signal to said vehicle, and wherein said sequence control means is located in said vehicle and includes receiver means for receiving said actuation signal from said transmitter means.

3. The automatic detection system of claim 2 wherein said sequence control means includes first and second integrated-circuit timers and means for triggering said second timer when said first timer times out.

4. The automatic detection system of claim 3 wherein said electrical system components further include parking lights, wherein said supplying means includes horn switch means for energizing said horn and light switch means for energizing said parking lights, and wherein said sequence control means further includes means for actuating said horn switch means and said light switch means at the end of the predetermined sequence whereby operation of said horn and said parking lights provide aural and visual indication of the completion of the predetermined sequence.

5. The automatic detection system of claim 4 wherein said indicator lights include turn signals, said supplying means further includes turn signal switch means for energizing said turn signals, and wherein said sequence control means further includes means for repetitively actuating said turn signal switch means during the predetermined sequence.

6. A method of automatically detecting the condition of electrical system components of a vehicle having a battery and a plurality of electrical system components, said method comprising the steps:

(a) generating an actuation signal at a location remote from said vehicle;

(b) selectively supplying power to a plurality of electrical system components including vehicle headlights, indicator lights and horn, said supplying step including energizing particular ones of said electrical system components through a plurality of separately actuatable switch means;

(c) actuating said plurality of switch means in a predetermined sequence in response to said actuation signal, and

(d) maintaining at least one of said electrical system components deenergized at any one time during the predetermined sequence,

wherein said actuating step includes sequencing entirely through the predetermined sequence in response to said actuation signal,

whereby all of said electrical system components are automatically energized in response to a single actuation signal while the instantaneous current drain from the battery of said vehicle is limited.

7. The method of claim 6 further comprising the steps:

(e) transmitting said actuation signal to said vehicle; and

(f) receiving said actuation signal with a receiver located in said vehicle,

wherein said actuating step is accomplished with a sequencer located in said vehicle and actuated by said receiver in response to reception of said actuation signal, said sequencer including means for automatically sequencing entirely through the predetermined sequence once actuated.

8. The method of claim 7 wherein said electrical system components further include parking lights, said method further comprising the step:

(g) intermittently energizing said horn and continuously energizing said parking lights at the end of said actuating step whereby operation of the vehicle horn and parking lights provides aural and visual indication of the completion of the predetermined sequence.

9. The method of claim 8 wherein said indicator lights include turn signals, said method further comprising the step:

(h) automatically, repetitively energizing said turn signals during said actuating step.

10. The method of claim 9 wherein said vehicle includes an internal combustion engine and a starter circuit for starting said engine, said method further comprising the step:

(i) conducting current from said battery to said starter circuit in response to reception of said actuation signal and before commencing said actuating step,

whereby said vehicle engine is running when said actuating step is performed.
