汽车自动入库系统

　　本项目设计一种基于超声波扫描测距和磁强计加速度计姿态测量的嵌入式自动倒车入位系统。在车辆上安装超声波扫描测距装置，通过扫描多点测量，获取车位位置尺寸信息，车载磁强计加速度计组成车辆的导航系统，获取车辆的位置航向信息。该设计基于对理想泊车路径的规划，通过BF537数字信号处理器作为主控单元对车辆的运动进行控制，实现了在垂直泊车环境下的安全泊车任务。但由于时间的限制，本次设计没有完成平行泊车环境的泊车任务，有待在今后的研究中解决。

　　Vehicle Automatic Parking System

　　In this project, we design an embedded Vehicle Automatic Reversing Parking System based on scanning ultrasonic distance measurement as well as magnetometer/accelerometer attitude measurement. The ultrasound scanning devices are mounted around the vehicle, to obtain the size and location information of the parking place through multipoint measurement, while the magnetometer and accelerometer give the vehicle heading direction. The main control unit, BF537, will give out an ‘optimal path into place’ after calculating the above information, then control the car to move the into the parking place safely. In this project, we parking the car successfully when the car is perpendicular to the carport. But we have not designed how to parking the car when it in parallel with the car port because the deadline is approaching. That will be discussed in our next study.
