The invention provides a roadside vehicle OBU triggering and positioning method. Whether a target vehicle enters a target parking space is sensed based on a roadside reader; when it is sensed that thetarget vehicle is driven into the target parking space, an OBU loaded on the target vehicle is awakened; a communication connection between the OBU and the roadside reader is established to realize handshake of the OBU and the roadside reader; and when handshaking of the two parties succeeds, unique identification information of the target vehicle is acquired based on the roadside reader, and thetarget parking space into which the target vehicle is driven is calibrated and positioned based on the roadside reader. The communication connection with the roadside reader is established through triggering the OBU of the vehicle so that the vehicle positioning is obtained, the management is convenient and the error-tolerant rate is improved.
本发明提供了路侧车辆OBU触发和定位的方法,基于路侧阅读器感应目标车位中是否有目标车辆驶入;当感应到目标车位中有目标车辆驶入时,唤醒装载在目标车辆的OBU;建立OBU与路侧阅读器的通信连接,实现双方握手;当双方握手成功时,基于路侧阅读器获取目标车辆的唯一识别信息,同时基于路侧阅读器对目标车辆驶入的目标车位进行校准定位。通过对车辆的OBU进行触发,建立与路侧阅读器的通信连接,进而获得车辆定位,便于管理,提高容错率。
