Problems solved by technology

However, the driving conditions of the vehicle are complex and changeable, and the calorific value or cooling capacity of other parts of the vehicle has great uncertainty. Therefore, a large amount of data calibration is required to simulate the thermal management strategy of the vehicle under different working conditions, resulting in the thermal management strategy being too large. Complicated; and some working conditions are difficult to simulate, resulting in incomplete calibration data, unreasonable thermal management strategy, not energy-saving, and affecting the cruising range of the vehicle

Embodiment Construction

[0057] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with this application. Rather, they are merely examples of methods and apparatus consistent with aspects of the present application as recited in the appended claims.

[0058] figure 1It is a flow chart of a vehicle thermal management method for a range-extended vehicle according to an exemplary embodiment. The thermal management method of the present application can be applied to the vehicle's own VCU (Vehicle Control Unit, vehicle controller), and the VCU executes the operation steps of the method. The method specifically includes the following steps:...

Abstract

The invention relates to a whole vehicle heat management method and device for an extended-range vehicle model. The method comprises the following steps: recognizing the type of a heat management request signal when the heat management request signal is received; determining a corresponding input variable and a regulation and control object according to the type, wherein the input variable is selected from vehicle state parameters; and performing fuzzy control on the regulation and control object according to the input variable. A power fuzzy control mode is adopted, so that data calibration and working condition simulation are not needed, a large amount of data calibration is saved, and the problem that a control strategy is unreasonable due to incomplete data calibration is fundamentallysolved; and the complexity of the control strategy is reduced, the heat management effect of the whole vehicle is improved, and the unexpected effect of the whole vehicle is avoided.

Description

technical field [0001] The present application relates to the technical field of automobile thermal management, and in particular to a method and device for a heat pipe of a whole vehicle of an extended-range vehicle. Background technique [0002] With the continuous development of the new energy industry, the society pays more and more attention to the mileage of new energy vehicles. The research and development of electric vehicles with long mileage is currently a popular development direction of new energy vehicle OEMs. Therefore, electric vehicle models with extended range Came into being. [0003] The working principle of the extended-range model is mainly to rely on the engine to drive the generator to generate electricity, and then charge the battery; or the engine directly drives the motor to work. Compared with pure electric vehicles, the main advantages of extended-range vehicles are long cruising range, high engine efficiency, low battery power, small size, and n...
