[0002] As an important means of transportation, the rise of consumer ability brings changes in consumer concepts. Current consumers' evaluation of vehicle performance is no longer limited to appearance, power economy and driving performance, and ride comfort has become an important evaluation index, and thermal comfort is an important part of ride comfort.

[0003] The automobile air conditioning system is an important part for adjusting the thermal comfort of the passengers. With the help of the air blower, the cold (hot) air is transported to each air outlet through the air pipe and then flows to the passenger cabin, thereby improving the thermal comfort of the driver (cool in summer and warm in winter). In cold weather, the influence of the air temperature in the vehicle on thermal comfort is most obvious. Too high or too low air temperature in the vehicle will make people feel uncomfortable. Because the hot air has a low density and the hot air rises, the air conditioner adopts the foot blowing mode when evaluating the heating performance of the vehicle. The thermal comfort of the vehicle is evaluated by the average temperature of the feet and the feet in the passenger cabin.

[0004] However, although the traditional evaluation method can meet the factory standard, when the customer drives, the driver's feet are basically fixed near the accelerator, brake and clutch, and cannot freely choose the placement position, which causes the "yin and yang feet" phenomenon.

[0041] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of the invention are illustrated in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0042] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0044] Example 1

[0045] like Figure 1 The diagram shows a flowchart of a method for evaluating the temperature of the driver's seat foot area according to the present invention. This method includes the following steps S01-S03, wherein:

[0046] S01. Build a three-dimensional simulation geometric model, set boundary parameters, and generate a mesh.

[0047] A three-dimensional simulation geometric model was constructed, which included the entire air conditioning and ventilation system, the crew enclosed cabin, the driver, the crew, and the seats.

[0048] Set boundary parameters, and set the blower speed, internal circulation parameters, external circulation parameters, evaporator / heater core resistance, air physical property parameters, etc. based on experimental data;

[0049] The dimensions of the face and volume grids for the driver and passengers, the grid size of the ventilation duct openings, and the boundary layer grid of the face wall are set, wherein the face and volume grid sizes are used to establish monitoring points.

[0050] In the design of the entire air conditioning air circuit system, different blower sizes, different duct path air resistance, and different duct routing designs will all affect the thermal comfort of the occupants. For example, if the blower horsepower is too small, it cannot pump a larger volume of air to the air outlet, which will inevitably cause the passenger compartment to heat up too slowly; or, even if more airflow is pumped to the air outlet, due to the design of the air outlet position, it cannot be guaranteed that the airflow will cover the occupants' foot area, which will inevitably cause the occupants' feet to not feel the heating effect.

[0051] In engineering simulation analysis, it is necessary to quantify this subjective evaluation index in order to illustrate the different heating performance brought about by different designs.

[0052] S02. Divide the same foot model of the driver to generate a first cluster region and a second cluster region, and set up several monitoring points in the first cluster region and the second cluster region respectively.

[0053] Because the temperature sensation is inconsistent between the area below the ankle and the area below the ankle during driving, the area below the ankle is designated as the first cluster area, and the area from the ankle to the calf is designated as the second cluster area.

[0054] The left and right foot models of the driver's model are divided separately to generate a first left cluster region, a second left cluster region, a first right cluster region, and a second right cluster region. The first left and first right cluster regions are the areas below the ankle in the left and right foot models, respectively, while the second left and second right cluster regions are the areas above the ankle.

[0055] like Figure 2 and Figure 3 As shown, based on the first right cluster region and the second right cluster region, five first cluster region monitoring points, R1, R2, R3, R4 and R5, are divided in the first right cluster region, and two second cluster region monitoring points, R6 and R7, are divided in the second right cluster region.

[0056] R1 is located at the front of the right foot, R2 and R3 are located on both sides of the forefoot, R3 is located on the side of the right foot closer to the left foot, R4 is located at the junction of the instep and ankle, R5 is located at the heel, R6 is located on the side of the right calf away from the left foot, and R7 is located behind the right calf, with R6 and R7 at the same horizontal height.

[0057] The left-foot model has five monitoring points for the first cluster region, L1, L2, L3, L4 and L5, which are symmetrical to the first right cluster region in the first left cluster region. It also has two monitoring points for the second cluster region, L6 and L7, which are symmetrical to the second right cluster region in the second left cluster region.

[0058] In this embodiment, the temperatures of the seven monitoring points L1, L2, L3, L4, L5, L6, and L7 on the left foot model of the driver at a certain moment in the foot blowing mode are 33.1°, 35.0°, 34.6°, 35.5°, 35.4°, 36.5°, and 34.6°, respectively; and the temperatures of the seven monitoring points R1, R2, R3, R4, R5, R6, and R7 on the right foot model of the driver are 38.2°, 38.3°, 38.1°, 38.3°, 36.2°, 38.7°, and 37.0°, respectively.

[0059] S03, acquiring the monitoring temperature of the monitoring points, and monitoring the temperature difference between any two monitoring points on the same foot model, comparing the monitoring result with the preset value, and obtaining the evaluation result.

[0060] The temperatures of R1, R2, R3, R4, R5, R6, and R7, and L1, L2, L3, L4, L5, L6, and L7 are monitored, and the monitoring temperatures are recorded. The temperature difference between any two monitoring points on the same foot model is monitored to obtain the average value of the temperature difference between the symmetric monitoring points in the left foot model and the right foot model, the maximum left temperature difference value in the left foot model, and the maximum right temperature difference value in the right foot model.

[0061] In this embodiment, the temperature difference values between the symmetric monitoring points in the left foot model and the right foot model are 5.1°, 3.3°, 3.5°, 2.8°, 0.8°, 2.2°, 2.4°, and the average value is 2.9°.

[0062] The maximum left temperature difference value in the left foot model is the difference between L6 and L1, which is 3.4°.

[0063] The maximum right temperature difference value in the right foot model is the difference between R6 and R5, which is 2.5°.

[0064] After obtaining the average value, the maximum left temperature difference value, and the maximum right temperature difference value,

[0065] The average value is compared with the preset average threshold value, and the maximum left temperature difference value and the maximum right temperature difference value are compared with the preset temperature difference threshold value.

[0066] If the average value is not greater than the preset average threshold value, and the maximum left temperature difference value and the maximum right temperature difference value are not greater than the preset temperature difference threshold value, there is no "yin-yang foot" phenomenon.

[0067] If the average value is greater than the preset average threshold value, or the maximum left temperature difference value is greater than the preset temperature difference threshold value, or the maximum right temperature difference value is greater than the preset temperature difference threshold value, it is evaluated as "yin-yang foot" phenomenon.

[0068] In this embodiment, the preset average threshold is 4 degrees, the preset temperature difference threshold is 7 degrees, based on the average value 2.9 degrees, the maximum left temperature difference value 3.4 degrees, and the maximum right temperature difference value 2.5 degrees, it can be concluded that the thermal comfort of the driver meets the standard, and the "yin and yang feet" phenomenon will not occur.

[0069] In summary, after building a three-dimensional simulation geometric model, setting boundary parameters, and generating a grid, the foot model in the established human body model is divided to generate a first clustering area and a second clustering area for the driver with the same foot model, and a plurality of monitoring points are arranged in the first clustering area and the second clustering area respectively; the temperature of the above monitoring points is monitored, the monitoring temperature of the monitoring points is obtained, and the temperature difference of each two monitoring points on the same foot model is monitored, the result of the temperature difference monitoring is compared with the preset value, and the evaluation result is obtained. The present application provides a thermal comfort evaluation method special for the driver, which accurately and comprehensively describes the thermal comfort of the driver, and can effectively avoid the "yin and yang feet" problem of the driver's left and right feet.
