title: Vehicle safety technology text: road accidents. The initial safety features were the safety glass, four-wheel hydraulic brakes, seat belts, and padded dashboards. A scientific approach to vehicle safety began in 1934 when General Motors conducted the first crash barrier test. Gradually, the existing systems were stabilized followed by introduction of disc brakes and anti-lock braking system. Introduction of hi-tech safety systems began in the year 1995 with Electronic Stability Control (ESC). The lane departure warning system was introduced in the year 1999 and the radar assisted adaptive cruise control was introduced in 2005. Theses advanced hi-tech systems are not standard parts in all cars. title: Automotive navigation system text: Automotive navigation system An automotive navigation system is part of the automobile controls or a third party add-on used to find direction in an automobile. It typically uses a satellite navigation device to get its position data which is then correlated to a position on a road. When directions are needed routing can be calculated. On the fly traffic information can be used to adjust the route. Dead reckoning using distance data from sensors attached to the drivetrain, a gyroscope and an accelerometer can be used for greater reliability, as GPS signal loss and/or multipath can occur due to urban title: Electro Gyrocator text: Electro Gyrocator The Electro Gyro-Cator was claimed to be the world's first automated commercially available automotive navigation system. It was co-developed by Honda, Alpine, and Stanley Electric Co.. Unlike most navigation systems of today, it did not use GPS Satellites to maintain its position and discern movement of the vehicle. Rather, it was an Inertial navigation system, because it contained a helium gas gyroscope that could detect both rotation and movement. A special servo gear was also attached to the transmission housing to feed information to the Gyro-Cator to help maintain position, map speed and distance traveled. Transparent maps were title: History of the automobile text: vehicle on the roads in Camborne. The first automobile patent in the United States was granted to Oliver Evans in 1789. During the 19th century attempts were made to introduce practical steam powered vehicles. Innovations such as hand brakes, multi-speed transmissions and better steering developed. Some commercially successful vehicles provided mass transit until a backlash against these large vehicles resulted in the passage of legislation such as the United Kingdom Locomotive Act (1865), which required many self-propelled vehicles on public roads to be preceded by a man on foot waving a red flag and blowing a horn. This effectively halted title: GPS navigation device text: it could become a commercial reality. In 1989, Magellan Navigation Inc. unveiled its Magellan NAV 1000, the world’s first commercial handheld GPS receiver. These units initially sold for approximately US$2,900 each. In 2000, the Clinton administration removed the military use signal restrictions, thus providing full commercial access to the US GPS satellite system. In 1990, Mazda's Eunos Cosmo was the first production car in the world with a built-in GPS navigation system. In 1991, Mitsubishi introduced GPS car navigation on the Mitsubishi Debonair (MMCS: Mitsubishi Multi Communication System). In 1997, a navigation system using Differential GPS was developed as a
