The invention discloses a hybrid power vehicle SOC preserved energy management method, and relates to a management method. The hybrid power vehicle SOC preserved energy management method comprises the steps of calculating demanded driving power; calculating demanded battery power; determining an engine working point; determining an electric generator working point; determining a motor working point. According to the hybrid power vehicle SOC preserved energy management method, starting by keeping the battery SOC at a higher level, energy managing and distributing are conducted to make a battery have higher power and energy margin, so that a motor can assist the engine at a larger power and longer time under the working conditions that large driving power is needed by fast acceleration and the like, and a higher dynamic performance index of a heavy vehicle is achieved; on the premise that basic requirements such as fuel economic efficiency and vehicle drive are met, the proposed control strategy realizes the function of series-parallel hybrid system energy management and expected battery SOC retentive goal.
