The driverless car Google, often called Google Car (in French: Google car) is an autonomous car being developed by Google X, a subsidiary of Google.

The project was launched by Sebastian Thrun, director of Stanford also Artificial Intelligence Laboratory and co-inventor of the Street View application. He was then taken by Chris Urmson.

Two types of vehicles are being tested: one modified production vehicles, like the Toyota Prius, and the other the "Google car" electric vehicle designed entirely by Google without flying or commands accelerator and brake.

                        

The autonomous car is allowed to travel on public roads in several US states, always with a driver behind the wheel to take control if necessary.

In October 2010, Google announced it has developed an autopilot system to help automotive radars, video cameras and GPS already installed on seven vehicles - six Toyota Prius, an Audi TT - which covered more than 225,000 km Californie1,2 without having provoked accident1.

This project started under the leadership of Sebastian Thrun, who won the DARPA Grand Challenge in 2005, within the team Stanford1,3,4 university. In his team he has surrounded Chris Urmson to develop the software, Anthony Levandowski for hardware and Mike Montemerlo for cartographie3.

The project is then taken by Urmson when Sebastian Thrun is dedicated to Udacity education project (in). Anthony Levandowski also engineer since 2007 for Google Street View and Google applications Maps3.

                      

Over 10 million accidents per year in the United States, 9.5 million are due to humaine3 error. Brin, Google co-founder, says that most cars are used for an hour or two a day, the rest of the time they stay in the garage or in a public parking. If its autonomous car project sees large-scale day, the very notion of car ownership could be questioned leaving room for a vehicle loan system in the manner of a driverless taxi while more flexible to use than public transport like bus or métro3.

More cars driven by software, so without fatigue or inattention, could enable safer driving even with reduced distances between each vehicle. The weight of the cars could be alleviated if the risk of shock is diminished, which would also reduce vehicle consumption and therefore pollution1.

Alongside this project that implements a production car bristling with sensors and software, Google is developing its own two-seater. Presented in 20145, it is an electric vehicle with a maximum range of 130 km and can reach a speed of 40 km / h. Their peculiarity is to have no steering wheel or accelerator control and brake. After being tested on the test track, the "Google Car" designed entirely by Google circulated since summer 2015 on Californian roads with an onboard engineer who can take control.

                       

The autopilot system uses a lidar, camera, radar, a GPS receiver and sensors on the wheels motrices4.

The vehicle must be driven ordinarily once in the path then it will borrow independently, so that a team checks the vehicle recorded all important signals along the path. The vehicle has more then only manage the traffic changes during autonome7 trip.

One of the limitations of the system is its inability to act on the actions of a police officer making the circulation7. The system is not tested under all weather conditions such as snow or fog.
