Security systems, remote control keys, theft deterrent systems. |
| Remote control keys |
Remote control keys and key fobs transmit a coded signal that is received by the vehicles theft deterrent module. |
|
| Theft deterrent systems | Theft deterrent systems aim to prevent the vehicle being entered, started or driven by reacting to input from devices such as door locks and vibration sensors, and by controlling such things as the starter motor or engine to immobilize the vehicle. | |
| Entertainment & peripheral systems | Integrated communications |
Modern vehicles integrate audio, video and communication systems into a network. |
| Body controlled lighting systems |
In modern vehicles ambient light sensors are used to automatically turn the headlights on in low light situations. Other body control lighting features can include: automatic 'dipping' headlights; delayed 'off' headlights; and headlight warning alarms. |
|
| Proximity sensors |
Proximity sensors are mounted in the front or rear bumpers. The control unit determines the distance between the sensor and an obstacle by measuring the time taken for sound waves to leave and return to the sensor. |
|
| Reflective displays | Reflective displays use a mirror embedded in the dash so the instruments appear further away than they actually are. The driver’s focal point changes less when looking from the road to the instruments and back. | |
| Satellite assisted systems | Global positioning satellites |
A system known as a Global Positioning System, or GPS, can be used to determine the exact location of a vehicle on the earth’s surface. |
| Triangulation/ trilateration |
Trilateration or triangulation is the system whereby a vehicle's location is determined by forming a triangle with a group of four or more satellites. |
|
| Satellite navigation |
Once a vehicles position is determined via trilateration, software can be used to generate an accurate map of the area. The GPS continues to provide updated information to ensure accuracy of the map data. |
|
| Telematics | Automotive telematics is a satellite-based system that combines two-way communication and information technology within the vehicle. |
