摘要
为了更好的研究自动泊车系统,提出一种能利用超声波测距原理来引导汽车根据确定轨迹到达指定停车位置的自动寻迹泊车系统模型。该系统模型采用了时延估计法,超声波收发技术,无线收发技术等,在系统设计时,按照比例,使用模型小车和模型车位代替真实车辆入位进行可行性测试。测试结果显示,模型小车可以根据规定的轨迹在允许的误差范围内到达指定模型车位上,并且具有较高的稳定性。
In order to study the automatic parking system deeply,it introduces a model about automatic tracing and parking system using the ultrasonic distance measurement that can guide the automobile to set in the parking position by the special trace.This system model has used the method of latency estimation,the ultrasonic wave receiving and sending technology and wireless transceiver technology.In practice,we utilize a model car and model parking position according to a certain proportion,for replacing the real parking vehicles to carry on the feasible test,the result demonstrated that the model car could arrive the model parking position in the permission error range,and has the high stability.
