Abstract

An electronic logic keyboard controls relay circuits in a tamper-proof box on a vehicle bulkhead. An input of a correct sequence to the keyboard with five seconds is necessary for activation of ignition and other vehicle electrical systems. A warning light on the keyboard is activated aftwo incorrect input sequences and after two further incorrect sequences the horn and hazard warning lights are activated.

Description

SPECIFICATION Motor vehicle security device This invention relates to a sequence selector electronic switch for a motor vehicle security device.
Switching on an electrical circuit in order to operate an electrical appliance invariably means the flicking of a switch thereby making a direct and immediate contact thus providing instant power to enable the appliance to be used immediately.
Sometimes such use of the appliance is not authorised nor desirable.
In the case of the motor vehicle unauthorised uses amounted to some 345,000 recorded illegal instances during 1986.
According to the present invention a number of selectors must be operated in the correct sequence in order to enable the power contact to be made before use of the motor vehicle is possible.
The device is in two (2) parts although such a feature is not essential to the invention.
The first part of the device is in the form of a multiple selector display unit denoted by KDU-1 in the Fig. SS-01 and which may be mounted on the dashboard panel, a console or some point as to be accessible.
The multiple selector is connected to the second part, a tamper-proof box shown as TPB-1 in the diagram SS-01.
The tamper-proof box TPB-1 in this case contains the relay circuits and may be fitted to the motor vehicle as part of, or remote from the multi-sequence selector, which in this case contains the logic circuits.
When this device is fitted to a motor vehicle insertion of an ignition key or the switching on of a remotely placed switch within the power lead from the battery will switch on the power to the Control Box-TPB-1-but will not enable the ignition circuits or other electrical circuits to be switched on.
On operating the multiple selector in the correct sequence the motor vehicle will be energised, ready for use. Visible evidence will be seen when the ignition lights of the motor vehicle are lit.
Visible evidence may be displayed also by the green Light Emitting Diode-LED-in the multiple sequence-selector unit KDU-1.
A pre-determined period of time is allowed from the time of the first correct input digit to the correct completion of the logic sequence. Failure to complete the correct sequence within the pre-determined time will constitute a failure and the ignition circuits and other electrical circuits will not be energised.
Once the correct sequence has been input within the time limit the motor vehicle may be started and operated in the normal way.
If an incorrect sequence is input no power contact will be made. If incorrect input is continued at the end of a pre-determined number of inputs a red warning light will be displayed on the red Light Emitting Diode-LED-in KDU-1.
If incorrect input continues at the end of a further predetermined number of input sequences visible and audible vyarning signals on the motor vehicle will be activated in the form of flashing hazard lights and the horn of the car, this indicating unauthorised attempt to use the motor vehicle.
If the warning light as indicated by the red LED, and/or the other alarm systems are activated then by switching off the remote switch or by removal of the ignition key the red LED and the alarm systems will be de-activated and the device will be reset atuomatically ready to accept a correct sequence input.
A specific embodiment of the invention will now be described by way of an example with reference to the accompanying Figs. SS-01, SS-02, SS-03, SS-04, SS-05 (a) and (b).
This example is a device in two (2) parts: (a) a Keyboard with twelve (12) keys and containing the logic circuits and (b) a Tamper-proof box which contains the relay circuits.
This unit is programmed such that it requires four (4) digit input sequence which must be completed within five (5) seconds from the time the first correct input is made.
If the correct input sequence is made within five (5) seconds from the first to the last input, the ignition and other electrical circuits of the motor vehicle will be activated, and the motor vehicle may be started and operated in the normal way.
If an incorrect sequence is input no power contact will be made. If a second incorrect sequence is input a warning light displayed by the red LED (Light Emitting Diode) is lit.
In this example, if a further two (2) incorrect sequences are input audible and visual alarm signals in the form of the horn and the hazard warning lights will be activated.
