The invention discloses an Internet of Vehicles remote intelligent vehicle locking function emergency unlocking operation method, relates to the technical field of engine control, and solves the technical problem that existing emergency unlocking excessively depends on a terminal and a CAN network. The method comprises the following steps: setting a vehicle locking switch of an electrically connected engine ECU; acquiring an emergency unlocking request code; inputting the emergency unlocking request code into the engine ECU through the vehicle locking switch; judging whether an emergency unlocking condition is met or not by the engine ECU; if the emergency unlocking condition is met, activating a fixed secret key as an emergency unlocking password, successfully unlocking emergently, adding1 to the number of unlocking times, and starting to record the unlocking time; otherwise, failing the emergency unlocking and quitting; and if the unlocking time reaches the set time, restoring the engine ECU to the vehicle locking state. According to the invention, the emergency unlocking request code is input through the vehicle locking switch for emergency unlocking, so that the problems of excessive dependence on a terminal and instability of a CAN network can be effectively solved.
本发明公开了一种车联网远程智能锁车功能紧急解锁操作方法,涉及发动机控制技术领域,解决现有的紧急解锁过于依赖终端和CAN网络的技术问题,方法包括:设置电性连接发动机ECU的锁车开关;获取紧急解锁请求码;通过锁车开关向发动机ECU输入紧急解锁请求码;发动机ECU判断是否满足紧急解锁条件;若满足紧急解锁条件,则激活固定秘钥作为紧急解锁密码,紧急解锁成功,解锁次数+1,并开始记录解锁时间;否则紧急解锁失败并退出;若解锁时间达到设定时间,则发动机ECU恢复锁车状态。本发明通过锁车开关输入紧急解锁请求码进行紧急解锁,可以有效克服过于依赖终端和CAN网络不稳定的问题。
