The invention discloses a low-power-consumption automobile body controller and a control method thereof. The control method of the low-power-consumption automobile body controller includes the following steps that 1, after an automobile body control system (BCM) is powered on, an automobile automatically enters and keeps a normal mode; 2, a switch collecting module collects automobile body control switch signals and transmits the signals to the automobile body controller, and when meeting a hibernation condition, the BCM enters a hibernation state; 3, when the BCM in the hibernation mode is woken up by external interruption, the BCM enters the normal mode, and if internal timer interruption waking occurs on the BCM, the BCM enters a temporary waking mode; 4, when the BCM in the temporary waking mode is woken up by the external interruption, the BCM enters the normal mode; if the BCM receives effective RKE data flows within certain time, a three-level filtering method is adopted to judge whether the BCM enters the normal mode or not.
