The invention discloses a vehicle storage battery power shortage prevention system and a vehicle control method.The vehicle control method comprises the steps that a magnetic latching relay is controlled to be disconnected in response to vehicle power-off requests, so that power supply of a storage battery and a vehicle electrical load is stopped, and the vehicle power-off requests comprise an active request and a passive request; when a vehicle is in a power-off state, if the keyless entry switch is switched on or the vehicle door microswitch is switched on, the keyless entry switch or the vehicle door microswitch provides a high level for one end, connected with the storage battery, of the magnetic latching relay through a corresponding triode; the magnetic latching relay is activated such that the battery is powered with a vehicle electrical load. The magnetic latching relay can achieve power supply on-off of the storage battery and the vehicle electric appliance load, and the vehicle storage battery electricity shortage prevention system does not consume electric appliances of the storage battery and can well prevent electricity shortage of the storage battery after the vehicle is powered off.

    本发明公开了一种车辆蓄电池防亏电系统及车辆控制方法,所述车辆控制方法包括响应于车辆下电请求控制磁保持继电器断开,使得蓄电池与车辆电气负载停止供电,所述车辆下电请求包括主动请求与被动请求;车辆下电状态下若无钥匙进入开关被导通或者车门微动开关被导通,所述无钥匙进入开关或车门微动开关通过相对应的三极管为所述磁保持继电器与所述蓄电池连接的一端提供高电平,激活所述磁保持继电器使得所述蓄电池与车辆电器负载供电。本发明中磁保持继电器可以实现蓄电池与车辆电器负载的供电通断,该车辆蓄电池防亏电系统无消耗蓄电池电量的电器,可以在车辆下电后很好的防止蓄电池亏电。
