Vehicle security system
First Claim
1. A vehicle security system including an electronic circuit including, in an operative configuration thereof onboard a motor vehicle,a receiver for receiving a predetermined disarm signal from a compatible transmitter, for switching the circuit to a disarmed state when in an armed state;
- sensing means including a shock sensor for detecting a predetermined event of a shock on the vehicle indicative of the presence of a person at the vehicle; and
alarm means for warning, when the circuit is in its armed state, of a breach of security of the vehicle in response to a predetermined alarm trigger event,the circuit being configured to, when in its armed state, require for switching into its disarmed state both reception of the predetermined disarm signal and the detection of the predetermined event indicative of the presence of a person at the vehicle occurring within a predetermined time period.

Abstract
This invention relates to a vehicle security system. The invention provides a vehicle security system which can be armed and disarmed via a remote control device, e.g. an RF device. The system includes also sensing means which can sense a predetermined event indicative of the presence of a person at the vehicle, such as knocking on the vehicle. For disarming the system, it requires a disarm signal from a compatible remote control device as well as the predetermined event to occur within a predetermined short time period. Where a number of such systems are installed on a number of vehicles on the same lot, e.g. a dealership showroom, and are armed, one of them may be selectively disarmed via a remote control device common to all of the systems. Only the system which senses the predetermined event in addition to a disarm signal will be disarmed.
