[0071] S1032, the current vehicle speed, the external environment data, and the operating efficiency of the heat pump air conditioner are input into the multivariate nonlinear regression model to calculate the optimal speed parameter of the heat pump air conditioner.

[0072] In practice, simulation data of several vehicles is acquired. The simulation data of several vehicles are all known data, including vehicle speed, outside temperature, and heat pump air conditioner speed. The simulation data is used to build a model to obtain the corresponding nonlinear regression model. The current vehicle speed is obtained, and the current vehicle speed, external environmental data, and heat pump air conditioner operating efficiency are input into the multivariate nonlinear regression model to simulate the optimal speed parameters of the heat pump air conditioner at the current vehicle speed.

[0073] S104, calculate the vehicle's comfort index based on the optimal speed parameter and the perceived comfort parameter, and control the heat pump air conditioner based on the comfort index.

[0074] In practice, the optimal speed parameters and the perceived comfort parameters obtained above are input into a preset comfort index library for data processing. The indexes are calculated according to their corresponding index ranges. When the optimal speed parameters and perceived comfort parameters fall into the range of the corresponding comfort indexes in the comfort index library, the heat pump air conditioner is controlled according to the comfort index to improve the comfort of the occupants of the vehicle.

[0075] In summary, the vehicle heat pump air conditioning control method in the above embodiments of the present invention constructs the in-vehicle heat load by analyzing the vehicle's internal and external environmental data, and sets vehicle parameters by analyzing the in-vehicle heat load; calculates the working efficiency of the heat pump air conditioning using equipment parameters, calculates the occupants' perceived comfort parameters based on the internal environmental data, collects the vehicle's current speed, calculates the optimal speed parameter of the heat pump air conditioning using the current speed, external environmental data, and working efficiency, and controls the heat pump air conditioning based on the optimal speed parameter and perceived comfort parameters.
