The invention discloses a calibration parameter optimization method for a whole vehicle controller of a hybrid power bus, and relates to the technical field of hybrid power automobiles. The method mainly comprises the following five steps: selecting a whole vehicle constraint boundary and calibration response, calculating theoretical oil consumption per hundred kilometers based on average comprehensive energy transfer efficiency, making a whole vehicle energy management strategy based on optimal control of an engine, optimizing calibration parameters according to an energy management strategyframework, and determining a one-dimensional calibration parameter feasible area. The relationship between the calibration parameters of the vehicle control unit and the economy of the vehicle is fully considered; a whole vehicle energy management strategy framework is deeply analyzed; according to the framework, the calibration parameters of the vehicle control unit are optimized, the feasible areas of all the calibration parameters are determined through a method of combining theoretical analysis and experience, and the method is beneficial for quickly optimizing the calibration parameters of the vehicle control unit of the hybrid power bus, reducing the range of the feasible areas of the calibration parameters and shortening the research and development period of the vehicle control unit.
