The invention discloses a control method and a control system for a trailer mode of a passenger car, and belongs to the technical field of automobile intelligence. The control method specifically comprises the following steps: entering the trailer mode: an IVI judges whether a precondition is met or not, and when the precondition is met, the trailer mode is allowed to be activated; the IVI memorizes and stores the current setting state; the IVI sends an Autohold switch and an automatic clamping EPB function closing instruction to the ESP; if the current non-N gear IVI sends out a prompt, the prompt automatically disappears after the user needs to manually shift into the N gear; if the current EPB is in the clamping state, the IVI sends a command to control the EPB to be released; when the trailer exiting mode is activated, the IVI reads the setting state memorized and stored in the trailer activating mode; and the IVI sends an instruction to the ESP according to the setting state of the memory storage, so that the Autohold switch and the automatic clamping EPB function are recovered to the state before the trailer mode is entered. According to the system and the method, the problem that a gearbox is in a P gear or wheels are locked due to the fact that all related functions hindering vehicle dragging are not completely closed can be avoided.

    本发明公开了一种乘用车拖车模式的控制方法及控制系统,属于汽车智能技术领域,具体包括,进入拖车模式:IVI判断前置条件是否满足,当满足时拖车模式允许被激活;IVI对当前的设置状态进行记忆存储;IVI向ESP发送Autohold开关、自动夹紧EPB功能关闭指令;如果当前非N挡IVI发出提醒,用户需要手动挂入N挡后该提醒自动消失;如果当前EPB处于夹紧状态,则IVI发送命令,控制EPB释放;退出拖车模式:当退出拖车模式被激活,IVI读取激活拖车模式下记忆存储的设置状态;IVI根据记忆存储的设置状态给ESP发送指令,使Autohold开关、自动夹紧EPB功能恢复到进入拖车模式之前的状态。该系统及方法可避免阻碍车辆拖动的全部相关功能未全部关闭导致的变速箱处于P挡或车轮抱死问题出现。
