Driver assistance can provide a higher comfort level

The theme of "towards the application of the Big Dipper," the Third China's satellite navigation academic annual meeting opened here today. China Satellite Navigation System Management Office RAN Cheng said at the meeting: China's Beidou system is about to complete the "second step" construction tasks, the system has to provide commissioning services, the performance indicators to meet regional service requirements, the Beidou system is full to the application.

Ran Cheng, the 3 network satellite system building, will be launched to complete the "second step" Constellation deployment. Around the end of the Asia Pacific region users, provide free passive positioning, navigation, and timing services; in the application and popularization and industrialization, increasing the the Beidou chip terminal R & D efforts, industry and regional Compass demonstration projects steady progress, synchronous active in the development of satellite navigation field development planning and related policies, standards and intellectual property rights, promoting satellite navigation, the promote Compass industrialization process; ICG (Global Navigation Satellite System International Committee) will be held in China in the international cooperation, the Seventh Congress of gradual integration into the international the standard system of civil aviation, maritime, and other countries and regions to fulfill the responsibilities and obligations on the global satellite navigation users.

"Two bombs and one satellite" meritorious scientist, winner of the State Supreme Science and Technology Award, the Beidou satellite navigation system project chief architect of Sun Jiadong academician introduced, with the Beidou system trial operation in December last year, "kill binary star" was successfully launched in April of this year twelfth, thirteen Beidou navigation satellite, the Beidou system positioning, navigation, time service performance and improve application service and gradually extended to the field of transportation, meteorology, fisheries, forestry, mapping, resulting in significant social and economic benefits.

 Car driving safety is a concern of consumers. U.S. Visteon has done a survey showed that: car driving safety in the core of customers to the car. Most consumers believe that car security than the vehicle dynamics, comfort, economy important. Focus on vehicle safety, not only for drivers and passengers, but also to other people on the road.

Vehicle safety can be broadly divided into active safety and passive safety. Passive safety is roughly divided into two auto dvd and car dvd player categories: "the accident" when the role of collision safety and accident occurred "after the role of crash safety. Former suction body, seat belts, driver and co-pilot airbag, side airbags and curtain airbags, air bag control module and collision sensors, such as pedestrian protection, the latter, such as flame-retardant devices, automatic alarm, car black box. A wide range of active safety, from the ABS, EBD, TPMS, ESP, and then to the auxiliary systems and driver monitoring system, etc., to an increasing role intelligent. Car security system is one of the strong demand growth in the field of automotive electronics.

Since 1996, the foreign will airbags as standard configuration of mid-range cars. Since 2002, the international community has two passenger sensing seats, with tightening belts and sensor systems and airbags as standard, tightening belts and sensor systems in 2006 is expected to increase to 4, the sensor system is substantially increased in order to improve the collision detection capability and improve ride stability, which may constitute a unified airbags network.
