Electronic vehicle security system with remote control
First Claim
1. An electronic vehicle security system, comprising:
- an alarm;
apparatus for detecting intrusion attempts and generating intrusion signals in response to said detection;
circuitry for arming the system so that said alarm is activated in response to detected intrusion attempts;
circuitry for periodically flashing a light in accordance with a light energization duty cycle when the system is armed to provide a visual indication that the vehicle is protected by a security system;
a battery for supplying power to flash said light;
battery power conserving apparatus for conserving battery power, said apparatus including timer apparatus for timing the length of time said system has been armed, and apparatus for reducing the light energization duty cycle for said light upon expiration of a predetermined length of time since arming occurred.

Abstract
A multifunction vehicle security system, which includes a receiver connected to a control unit which processes received information and enables various functions. The user can increase or decrease the sensitivity of the system sensor, by merely pressing a button on the remote control to increase the sensor sensitivity, and another button to decrease the sensitivity. A special programming mode resets the system programmable features and values to factory settings, to quickly re-establish to a known state all or only preselected features. The system provides automatic silencing during night conditions of the system'"'"'s arming/disarming chirping to confirm the change of system state. The security system generates a door unlocking command to the vehicle'"'"'s power door locking system to unlock the doors in the event of a vehicle collision. A theft warning LED energy management system conserves battery power when the vehicle is left unattended for long periods of time. When the system is armed, a timer is started, and upon expiration of a time period, the LED activation duty cycle will be reduced from an initial duty cycle. The polarity of the door locking and unlocking signals is programmable, enabling the installer to match the polarity requirements of a particular vehicle. An enhanced panic mode is provided, wherein the vehicle doors are automatically unlocked if the vehicle ignition switch is off, or if the vehicle ignition switch is on, the doors will be automatically locked. The system provides installer programmability of the normally open/closed mode for the vehicle starter, ignition, and/or fuel pump disable relays.

5. An electronic vehicle security system, comprising:
-
an alarm circuit for generating an alarm in the event of an intrusion attempt; a controller for putting the system in an armed mode for protecting the vehicle, or in an unarmed mode permitting the vehicle to be operated; vehicle disabling circuitry operable when the system is armed to prevent operation of the vehicle, said circuitry including a relay switch actuatable from the controller, and wherein the controller provides a relay control signal which sets the relay to operate in either a normally open or normally closed mode; and is a programming circuit for programming the controller to set the relay control signal to establish the mode in which the relay operates. - View Dependent Claims (6, 7, 8, 9, 10, 11)
