基于汽车导航系统的机械式自动变速器换挡控制规律研究

Research on the Shift Control Rule of Automated Mechanical Transmission Based on the Navigation System

随着导航系统在汽车上的广泛应用,提出了利用车辆动力学的原理对导航系统的定位精度进行了校正,并提出了相应的理论方法和汽车在弯道上行驶时的换挡控制规律。仿真结果表明该换挡控制规律能够提高汽车在弯道行驶时的燃油经济性、行驶安全性和乘坐舒适性,同时也能延长离合器和制动器的使用寿命。

With the wide application of the navigation system to the automobile, the position accuracy of the navigation system is corrected based on the principle of vehicle dynamics, and the corresponding theory method and shift control rule of the automated mechanical transmission （AMT） of the vehicle running on crooked roads are presented. The simulation results show that the shift control rule can improve fuel efficiency, safety and comfort, also can prolong service life of the clutch and brake.
