针对不能满足平行泊车要求的狭小车位,提出了单向多次和双向多次路径规划方法。在确定了两种泊车轨迹的变量、碰撞约束函数以及规划目标后,利用matlab软件的非线性约束函数的优化功能求解泊车轨迹方程,并对两种路径规划方法进行仿真试验,结果表明,在相同的泊车环境下,两种路径规划方法都可实现安全顺利的泊车入位;通过实车试验进一步验证了所提出的路径规划方法的安全性和有效性。
針對不能滿足平行泊車要求的狹小車位,提齣瞭單嚮多次和雙嚮多次路徑規劃方法。在確定瞭兩種泊車軌跡的變量、踫撞約束函數以及規劃目標後,利用matlab軟件的非線性約束函數的優化功能求解泊車軌跡方程,併對兩種路徑規劃方法進行倣真試驗,結果錶明,在相同的泊車環境下,兩種路徑規劃方法都可實現安全順利的泊車入位;通過實車試驗進一步驗證瞭所提齣的路徑規劃方法的安全性和有效性。

For the narrow parking space which can not satisfy the requirement of parallel parking, we present two route planning methods: one-way multiple-route planning method and two-way multiple-route planning method. When variables, collision constraint function and planning objective of two parking trajectories are defined, we make use of optimization function of the nonlinear constraint function in MATAB to solve the parking trajectory equation, and these two route planning methods are simulated and tested, which show that , in the same parking environment, both of two route planning methods can make the car park safely with smaller parking length; safety and validity of the presented route planning methods are verified with vehicle test.
