The invention relates to a vehicle-mounted positioning anti-disassembly system. The invention particularly relates to an anti-disassembly system based on a vehicle body control system. The system comprises an electronic control unit; the electronic control unit receives detection data of a vehicle starting detection module, a vehicle closing detection module and a speed sensor through a CAN bus. The electronic control unit is connected with a random data generation module used for generating random numbers and encrypting the random numbers; the electronic control unit performs random number and encrypted random data transmission with the vehicle-mounted positioning module through a CAN bus, and the electronic control unit is connected with a random data comparison module used for comparingthe encrypted random data generated by the random data generation module with the encrypted random data generated by the vehicle-mounted positioning module. According to the technical scheme providedby the invention, the defect that in the prior art, the accuracy of judging whether the vehicle-mounted positioning terminal is dismounted is relatively low by cheating the ECU through an external analog signal can be effectively overcome.
本发明涉及车载定位防拆系统,具体涉及一种基于车身控制系统的防拆系统,包括电子控制单元,电子控制单元通过CAN总线接收车辆启动检测模块、车辆关闭检测模块、速度传感器的检测数据,电子控制单元与用于生成随机数并进行加密的随机数据生成模块,电子控制单元通过CAN总线与车载定位模块进行随机数、加密随机数据的传输,电子控制单元与用于对随机数据生成模块生成的加密随机数据与车载定位模块生成的加密随机数据进行对比的随机数据对比模块相连;本发明提供的技术方案能够有效克服现有技术所存在的能够通过外部模拟信号欺骗ECU、判断车载定位终端被拆除的准确性较低的缺陷。
