The invention discloses a commercial vehicle speed-limiting tamper control system and a tamper method thereof. The commercial vehicle speed-limiting tamper control system comprises an ABS/EBS system, a GPS system and an instrument system. The ABS/EBS system is used for anti-lock braking, braking and wheel speed calculation based on wheels, and the ABS/EBS system is composed of a controller, an electromagnetic valve and a sensor. The GPS system is used for information interaction between the vehicle and the platform and transmission of background information. Firstly, the speed is limited by taking the speed of a speed sensor (calculated by an instrument) as a standard; when the vehicle speed sensor is detached or the vehicle speed source is abnormal, the speed is limited according to the vehicle speed calculated by the ABS wheel speed; when the vehicle speed of the vehicle speed sensor and the vehicle speed calculated by the ABS wheel speed are abnormal, the speed is limited by the GPS vehicle speed according to the GPS vehicle speed and the GPS displacement in a time period and by judging that the rotating speed of an engine is in a normal range, and when the vehicle speed of the vehicle speed sensor, the vehicle speed calculated by the ABS wheel speed and the GPS vehicle speed are abnormal, the vehicle locking logic is executed. Therefore, the speed of the vehicle is calculated through multiple nodes, speed limiting alarm and vehicle locking are carried out, and the anti-disassembly purpose is achieved.

    本发明公开一种商用车限速防拆控制系统及其防拆方法,包括:ABS/EBS系统、GPS系统以及仪表系统。ABS/EBS系统用于防抱死和制动以及基于车轮的轮速计算,且ABS/EBS系统通过控制器、电磁阀以及传感器构成。GPS系统用于车辆与平台的信息交互、后台信息的传递。首先以车速传感器(仪表计算)车速为准,进行限速;当车速传感器被拆或车速来源异常时,以ABS轮速计算的车速进行限速;当车速传感器车速、ABS轮速计算车速均异常时,以一个时间段内的GPS车速及GPS位移,并判断发动机转速在正常范围,则以GPS车速进行限速,当车速传感器车速、ABS轮速计算车速、GPS车速均异常则执行锁车逻辑。这样利用多节点计算车辆车速,进行限速报警、锁车,以达到防拆目的。
