中文摘要：
为解决驾驶员泊车问题,根据汽车在低速倒车过程的运动学特征,分析了汽车在一般平行泊车环境下碰撞障碍物的可能性,确定了泊车的约束边界.利用国内某款A0级轿车的基本尺寸作为计算依据,设计出两段圆弧的泊车路径,并且找出了行走路线对应的预备倒车区域.在该区域中的每一点汽车都有一段方向盘转角范围,驾驶员可以很容易试探到这个范围,并按照提供的路径作为参考进行倒车.通过汽车的实际操作验证了实现平行泊车的可行性.
英文摘要：
To solve car parking problem,the collision possibility between the car and the obstacle in the general parallel parking environment was analyzed and the boundary of constraint was calculated according to the kinematical behavior of the car in the low-speed back-up process.Based on the basic dimensions of a domestic A0-class car,the parking path consisting two arcs was designed and the starting area was determined.There is a range for steering wheel angle at every position in this area what drivers can easily find and follow the provided path to reverse.The actual operation of car verified the feasibility to realize the parallel parking.
