The invention relates to a low-cost mechanical locking anti-theft method for an electronic gear shifting vehicle type. An anti-theft authentication process of a gear shifting controller and a vehicle body control unit is adopted, and an identity authentication relation between the vehicle body control unit and the gear shifting controller is established; the anti-theft authentication process comprises the steps that when the whole vehicle leaves a factory, the same secret key is written into the two parts of the gear shifting controller and the vehicle body control unit; when a user uses a vehicle and starts authentication, a gear shifting controller sends a random number to a vehicle body control unit, and meanwhile, the gear shifting controller carries out mathematical operation according to a secret key and a seed to obtain a result A; the vehicle body control unit performs the same mathematical operation according to the secret key and the received random number to obtain a result B, and sends the result B back to the gear shifting controller; and the gear shifting controller compares the result A with the result B, if the result A is consistent with the result B, identity authentication succeeds, anti-theft authentication passes, and then passing result information is sent to a vehicle body control unit through a vehicle body CAN bus. According to the invention, 'steering column locking hardware' is cancelled, and the cost of the whole vehicle is reduced.
本发明涉及一种低成本的电子换档车型机械锁止防盗方法。采用换档控制器和车身控制单元防盗认证流程,建立“车身控制单元”与“换档控制器”之间身份认证关系;防盗认证流程是指:整车出厂时候,对换档控制器和车身控制单元两个零件写入同样一个秘钥;用户使用车辆,开始认证的时候,换档控制器发送随机数字给“车身控制单元”,同时自己根据秘钥和种子进行数学运算,得到结果A。车身控制单元依据密钥和接到的随机数字做同样数学运算得到结果B,发送回换档控制器;换档控制器将结果A和B进行对比,如果一致,则身份认证成功,防盗认证通过,再将通过的结果信息通过车身CAN总线发送给车身控制单元;本发明取消了“转向柱锁止硬件”,实现了整车成本的降低。
