The invention provides an anti-theft matching method and system for a hybrid vehicle. The method comprises the steps that when a whole vehicle is powered on, a first control instruction is sent to a PEPS and an HCU through a diagnosis terminal, so that the PEPS and the HCU both enter an extended diagnosis mode; a first SEED value sent by a PEPS is obtained through a diagnosis terminal, and a corresponding first KEY value is calculated according to the first SEED value, so that the PEPS generates a matching instruction according to the first KEY value through access limitation of the PEPS; a second SEED value sent by the HCU is obtained through the diagnosis terminal, and a corresponding second KEY value is calculated according to the second SEED value, so that a second control instruction is obtained through access limitation of the HCU and VIN codes are input into the HCU; enabling the HCU to receive a matching instruction through the second control instruction, so as to enable the PEPS to be matched with the HCU. According to the anti-theft matching method, the access limits of the PEPS and the HCU are removed respectively, so that the matching of the PEPS and the HCU is completed, the anti-theft matching of the hybrid electric vehicle is realized, and the defects in the prior art are overcome.
本发明提供了一种混合动力汽车防盗匹配方法及系统,该方法包括当整车上电时,通过诊断终端向PEPS以及HCU发送第一控制指令,以使PEPS和HCU均进入扩展诊断模式;通过诊断终端获取PEPS发送的第一SEED值并根据第一SEED值计算出对应的第一KEY值,以通过PEPS的访问限制并使PEPS根据第一KEY值生成匹配指令;通过诊断终端获取HCU发送的第二SEED值并根据第二SEED值计算出对应的第二KEY值,以通过HCU的访问限制并向HCU输入VIN编码得到第二控制指令;通过第二控制指令使HCU接收匹配指令,以使PEPS与HCU完成匹配。通过分别解除PEPS和HCU的访问限制,从而完成PEPS与HCU的匹配,实现了该混合动力汽车的防盗匹配,弥补了现有技术的不足。
