The invention discloses a commercial vehicle starting electric quantity protection control method and system, and the method comprises the steps: enabling a storage battery to supply power to electric equipment in a constant power network and a switching power network when a vehicle runs, disconnecting the power supply of the electric equipment in the switching power network when the vehicle is powered off, and detecting the electric quantity information of the storage battery in real time; and judging whether to cut off the power supply of the electric equipment in the constant power network according to the electric quantity information. The IBS sensor is adopted as a storage battery electric quantity detection tool, when the whole vehicle leaks electricity or is parked for a long time, the electric quantity of the storage battery can be detected, and the micro-control relay switch is controlled to be turned on or turned off according to the electric quantity of the storage battery; when the electric quantity of the storage battery is lower than the minimum starting protection electric quantity of the engine, all power consumption modules of the whole vehicle are automatically cut off, working in an extremely low power consumption mode is achieved, and the situation that the engine cannot be started or the storage battery is damaged due to over-discharge of the storage battery is avoided.

    本发明公开了一种商用车启动电量保护控制方法及系统,车辆运行时蓄电池为常电网络和开关电网络中的用电设备供电,车辆下电时,断开开关电网络中的用电设备的供电,实时检测蓄电池的电量信息,根据电量信息判断是否断开常电网络中的用电设备的供电。本发明采用IBS传感器作为蓄电池电量检测工具,当整车存在漏电或者长时间驻车时,可以检测蓄电池电量,根据蓄电池电量大小来控制微控制继电器开关的开闭;当蓄电池电量低于发动机最小启动保护电量时,自动切断整车所有耗电模块,实现以极低功耗模式工作,避免蓄电池过度放电导致的发动机无法启动或者蓄电池损坏。
