The invention discloses a vehicle-mounted hydrogen-oxygen fuel cell energy management control method and system. The method comprises the following steps: acquiring vehicle data; according to the whole vehicle gas-electricity control mode and the lithium battery SOC state, a fuel cell engine control mode is judged, and start-stop control is achieved; when the fuel cell engine is started and outputs power, determining the required power of the whole vehicle according to the power of the high-voltage electric appliance of the whole vehicle; judging the current load mode of the whole vehicle according to the average required power of the whole vehicle; according to the full-power switching effectiveness of the whole vehicle, the current load mode of the whole vehicle and the SOC state of the lithium battery, the fuel cell engine required power is determined; and taking the minimum numerical value in the fuel cell engine demand power, the fuel cell engine output power and the whole vehicle gas-electricity power amplitude limit as the fuel cell engine output power. According to the energy management control method, the fuel cell engine can meet the power requirement and the economical requirement of the whole vehicle in the whole vehicle application, and the durability of the fuel cell engine is improved.
