Manufacturers : Car electronics : Car security systems

Car security systems generally include sensors to detect disturbances to the vehicle, a deterrent subsystem (audible and visual indicators and anti-theft locks), a control mechanism for arming and disarming the security system, a power supply to operate the system; and a control unit that functionally interconnects all of the other elements. Automotive security systems often include immobilizer devices which protect a vehicle by disabling the vehicle's starter circuit to prevent unauthorized starting of the vehicle; disabling the vehicle's ignition system; or disabling both the starter circuit and the engine computer or another necessary system. Motion sensors, infrared detector, and ultrasonic wave detector detect movement of the vehicle. When the vehicle is moved or a vibration is transmitted through the vehicle to the motion sensor, that sensor is activated, or tripped. When any of these sensors detects an abnormal condition while the car security function of the apparatus is on, a siren is sounded and an engine starter is disabled when an ignition switch is subsequently turned on. Alarm devices are usually installed in a car to prevent a thief from entering the car. The alarm device makes use of one or more sensors to detect the intrusion of a thief. These security systems produce audible and visual alarm effects after conditions are detected that are indicative of an unauthorized tampering with a vehicle. An automobile engine starter system typically comprises a battery, a starter motor, a starter magnetic relay, and a starter switch. Automobile ignition security systems utilizes a hall-effect magnetic sensor which contains a single hall-effect element located in the ignition switch lock assembly to generate a specific voltage code. This code is utilized by a microprocessor of the ignition system of the vehicle to start the automobile.
