The invention relates to a method for optimizing energy consumption of a whole vehicle by power distribution of a fuel cell vehicle, which is used for performing power distribution on target demand power Preq output to a fuel cell system and performing whole vehicle energy distribution in cooperation with a power battery, and comprises the following steps: step 1, analyzing an optimal power point PF of the fuel cell system, step 2, performing charge and discharge limit analysis on the power battery, and step 3, analyzing the energy consumption of the whole vehicle. 3, making a gas-electricity power matrix; and 4, carrying out a control strategy of power distribution. On the basis of each power interval of the electric drive demand power Ptmr of the fuel cell and the SOC percentage of the power cell, a gas-electric power matrix is drawn in combination with charging and discharging zoning of the power cell, the gas-electric power matrix is inquired by collecting the current SOC residual electric quantity percentage and the current Ptmr value, Preq is rapidly output and distributed, energy flow distribution of the whole vehicle is achieved, and energy flow distribution of the whole vehicle is achieved. And the power control of the gas-electric vehicle model is realized more efficiently, so that the energy flow management of the whole vehicle is more economical.
