| 摘 要： | 本文采用基于TDOA算法的超声波定位为电动汽车感应式无线能量传输提供对准方法，并使用卡尔曼滤波结合超声波模块进行实验验证。为提高算法精度，本文基于TDOA算法超声波定位模型提出一种发射器位置计算方法；然后在算法原理推导过程中，分别对算法中影响定位精度的主要因素（如传感器位置布置形式、接收传感器间距、时间差测量误差、发射传感器高度等）进行了仿真和对比；最后将算法仿真结论进行实验验证，实现了在误差允许范围内的精准定位。本文的结论对采用TDOA算法进行超声波定位的方案及参数选取提供了一定的依据。

| Abstract: | In this paper, ultrasonic positioning based on TDOA algorithm is adopted in the alignment method for inductive wireless energy transfer of electric vehicle, which is then experimentally verified by a ultrasonic module with kalman filter . A transmitter position calculation method utilizing ultrasonic positioning based on the TDOA algorithm is first proposed to improve the accuracy. Then in the process of algorithm principle derivation, the main factors affecting the positioning accuracy (such as sensor position arrangement, receiver sensor distance, time difference measurement error, launch sensor height, etc.) are simulated and compared. And finally, the simulation results of the algorithm are validated experimentally to achieve precise positioning within the acceptable error range. The conclusion of this paper provides a certain basis for the scheme and parameter selection of ultrasonic positioning using TDOA algorithm. |
