基于CAN总线的车载导航与安全一体化系统

Integration of Vehicle Navigation and Security System Based on CAN Bus

随着道路上车流量的加大以及路况、天气、车辆性能等多方面因素的影响,使交通事故概率急剧攀升,将驾驶、导航与安全保护一体化集成显得非常必要。车载导航系统通过微惯性测量组合(MIMU)、磁强计、GPS组合导航,测量车辆实时的位置和姿态信息,并通过CAN总线与车辆安全保护系统相连,从而可以实现导航与安全一体化集成的目的。

With the rapid development of science and technology, and improvement of people's living standards, more and more people owned a car, which result in the pressure of traffic increase year by year, also, for many impact of factors, such as road conditions, weather, vehicle performance, and so on, the traffic accidents rose quickly. In order to make drivers driven more convenient and safer, vehicle navigation system and security research and application was very necessary. Through the integration of Micro Inertial Measurement Unit(MIMU), magnetometer and GPS navigation, Integration of Vehicle Navigation and Security System Based on CAN Bus measured real-time vehicle position and attitude information, and realized the purposes of integrated of vehicle navigation and security by vehicle CAN bus.
