本JAVA程序实现一个模拟汽车轨迹方案。我们有一个参照轨迹，通过这个参照轨迹算出汽车的实际轨迹。并且在电脑上显示出来。我们还可以动态的描点和制定汽车的参照轨迹。-The JAVA program to achieve a simulated vehicle track program. We have a reference trajectory, reference trajectory calculated by the vehicle' s actual trajectory. And displayed on the computer. We can also describe a dynamic reference point and the trajectory of the development of the car.
