说明：  不等半径泊车方法仿真代码，实现不等半径泊车算法的仿真，车辆参数如车长、车宽、转弯半径以及车位参数如长度、宽度均可调。
(Simulation code radius ranging from parking way to achieve a radius ranging from parking the simulation algorithm, vehicle parameters such as vehicle length, vehicle width, turning radius and parking parameters such as length, width can be adjusted.)
