Lots of classy control systems of the modern automobiles need measurements of vehicle’s attitude. The commercial GPS systems are method of option for measuring approach in lots of aircraft & farm automobile applications, however are not usually used on the automobiles. Prohibitive aspects of the commercial GPS systems on car include their high cost & significant loss of reliability & signal availability in the urban road settings.

The modern automobiles are prepared with various control systems, which improve passenger safety & comfort. These systems take in anti-lock brakes, disparity steering & cruise control. Recently, the automotive GPS systems also got added to lots of cars for exercise in positioning purposes, permitting driver to view their position on map, and get directions in the real time. Advent of the GPS receivers in the cars has efforts to improve existing systems, and to make new ones like car following & lane keeping control. Some of these systems need measurements of vehicle’s attitude.

Few other type of interesting integrations & functions of the automotive GPS control system are that color LCD monitors on a few automotive navigation systems that can as well be used to show television broadcasts and DVD movies. Some systems integrate with phones for the hands-free talking & SMS messaging. Automotive navigation control systems will include personal info management for meetings that is combined with traffic & public transport system.

Safety Features

Vehicles made by Subaru * Lexus, and Lexus’ company, Toyota, exclude many of features when vehicle is in the motion. Manufacturers state this is safety feature to evade driver being distracted. Lots of users have also complained that the passengers are not capable to enter location while in the motion, even if it is very safe to do. Additionally, the drivers have also complained that it is unsafe to pull off highway & stop than it is to enter destination in a system.

The automotive system is satellite navigation system that is designed for the exercise in automobiles. It normally makes use of GPS navigation system to obtain position data to place the user on road in unit’s map database. By using road database, unit will give directions to the other locations all along roads in its database. The dead reckoning utilizing distance data from the sensors attached to drive train, gyroscope and accelerometer is used for the greater dependability, since GPS signal loss and multipath will occur because of urban canyons and tunnels.

Advantages of this kind of GPS unit take in low cost and capability to move them simply to other automobiles. Their portability states they are simply stolen if left in the vehicle however can’t be stolen if driver carries it with him while he gets out. In addition not having compass, accelerometer and inputs from vehicle’s speed sensors, states that they can’t navigate as precisely by dead weighing up as a few built- in the devices when there is not any GPS signal. More current portable devices like TomTom 920 have inbuilt accelerometer to attempt and address this.
