Description

Technical Field

[0001] The present invention relates to the field of automobile air conditioning, and in particular to a method and system for evaluating the temperature of a foot in a main driver's seat, a readable storage medium and a vehicle. Background Art

[0002] As an important means of transportation, the increase in consumption capacity has brought about changes in consumption concepts. Currently, consumers' evaluation of automobile performance is no longer limited to appearance, power economy and drivability. Ride comfort has become an important evaluation indicator, and thermal comfort is an important part of ride comfort.

[0003] The automobile air conditioning system is an important component used to adjust the thermal comfort of passengers. With the help of a blower, the cold (hot) air is transported to each air outlet through the air duct and then flows to the passenger compartment, thereby improving the driver's thermal comfort (bringing coolness in summer and warmth in winter). In cold climates, the impact of the air temperature inside the car on thermal comfort is most obvious. Too high or too low air temperature inside the car will make people feel uncomfortable. Because the density of hot air is relatively low and the hot air flow rises, the air conditioner uses the foot blowing mode when evaluating the heating performance of the car. The thermal comfort of the vehicle is examined by measuring the average temperature of the feet and feet in the passenger compartment.

[0004] However, although the traditional evaluation method can meet the factory standards, when the customer is driving, the driver's feet are basically fixed near the accelerator, brake and clutch, and the customer cannot freely choose the placement, which leads to the "yin and yang feet" phenomenon. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a method, system, readable storage medium and vehicle for evaluating the temperature of the feet of the main driver's seat, aiming to solve the problem that although the current traditional evaluation method can meet the factory standards, when the customer is driving, the main driver's feet are basically fixed near the accelerator, brake and clutch, and the placement position cannot be freely chosen, resulting in the "yin and yang feet" phenomenon.

[0006] To achieve the above object, the present invention proposes a method for evaluating the temperature of the foot of a main driver's seat, the method comprising:

[0008] Dividing the same foot model of the main driver to generate a first cluster area and a second cluster area, and setting a plurality of monitoring points in the first cluster area and the second cluster area respectively;

[0009] The monitoring temperature of the monitoring point is obtained, and the temperature difference of each monitoring point 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.

[0010] 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 with the same foot model of the main driver, and a number of monitoring points are respectively set in the first clustering area and the second clustering area; the temperature of the above-mentioned monitoring points is monitored, and the monitoring temperature of the monitoring points is obtained, and the temperature difference of each monitoring point on the same foot model is monitored, and the result of the temperature difference monitoring is compared with the preset value, and an evaluation result is obtained. Starting from the particularity of the main driver, the present application provides a thermal comfort evaluation method dedicated to the main driver, which accurately and comprehensively describes the thermal comfort of the main driver and can effectively avoid the problem of "yin and yang feet" in the left and right feet of the main driver.

[0014] At least set the face and volume mesh sizes of the driver and passenger, the mesh size of the ventilation duct opening, and the boundary layer mesh of the face wall;

[0015] The surface grid and volume grid sizes are used to establish monitoring points.

[0016] According to one aspect of the above technical solution, the step of dividing the same foot model of the main driver to generate a first cluster area and a second cluster area, and setting a plurality of monitoring points in the first cluster area and the second cluster area respectively, specifically includes:

[0041] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0042] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0044] Embodiment 1

[0045] like Figure 1 The flowchart of a method for evaluating the temperature of the foot of the main driver's seat in the present invention is shown. The method for evaluating the temperature of the foot of the main driver's seat includes the following steps S01 to S03, wherein:

[0046] S01. Build a 3D simulation geometry model, set boundary parameters, and generate a mesh.

[0047] Build a three-dimensional simulation geometric model, which includes a complete air conditioning and ventilation system, a passenger cabin, a driver, passengers, and seats;

[0048] Set boundary parameters, such as blower speed, internal circulation parameters, external circulation parameters, evaporator / heater core resistance, air physical parameters, etc. according to experimental data;

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

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

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

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

[0053] Since the thermal sensations of the two areas below the ankle and above the ankle are inconsistent during driving, the area below the ankle is set as the first clustering area, and the area above the ankle to the calf is set as the second clustering area.

[0054] The left foot model and the right foot model of the main driver model are divided respectively to generate a first left cluster area, a second left cluster area, a first right cluster area and a second right cluster area, respectively. The first left cluster area and the first right cluster area are the areas below the ankles in the left foot model and the right foot model, and the second left cluster area and the second right cluster area are the areas above the ankles.

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

[0056] Wherein, R1 is arranged at the front end of the right sole, R2 and R3 are arranged at both sides of the forefoot area respectively, R3 is arranged at the side of the right sole close to the left foot, R4 is arranged at the connection between the instep and the ankle, R5 is arranged at the heel, R6 is arranged at the side of the right calf away from the left foot, R7 is arranged at the back of the right calf, and R6 and R7 are arranged at the same horizontal height;

[0057] The left foot model has five first cluster area monitoring points L1, L2, L3, L4 and L5 symmetrically set in the first left cluster area and the first right cluster area, and two second cluster area monitoring points L6 and L7 symmetrically set in the second left cluster area and the second right cluster area.

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

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

[0060] Monitor the temperatures of R1, R2, R3, R4, R5, R6 and R7, as well as L1, L2, L3, L4, L5, L6 and L7, and record the monitored temperatures. Monitor the temperature difference between any two monitoring points on the same foot model to obtain the average temperature difference between the symmetrical 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 differences of the symmetrical 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°, and 2.4°, respectively, with an average value of 2.9°;

[0062] The maximum left temperature difference in the left foot model is 3.4° between L6 and L1;

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

[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 a preset average threshold, and the maximum left temperature difference value and the maximum right temperature difference value are compared with a preset temperature difference threshold:

[0066] If the average value is not greater than the preset average threshold, and both the maximum left temperature difference value and the maximum right temperature difference value are not greater than the preset temperature difference threshold, then there is no "yin and yang feet" phenomenon;

[0067] If the average value is greater than the preset average threshold, or the maximum left temperature difference value is greater than the preset temperature difference threshold, or the maximum right temperature difference values ​​are both greater than the preset temperature difference threshold, it is evaluated as a "yin and yang feet" phenomenon.

[0068] In this embodiment, the preset average threshold is 4°, and the preset temperature difference threshold is 7°. Based on the average value of 2.9°, the maximum left temperature difference of 3.4°, and the maximum right temperature difference of 2.5°, it can be concluded that the thermal comfort of the driver's seat 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 with the same foot model of the main driver, and a number of monitoring points are respectively set in the first clustering area and the second clustering area; the temperature of the above-mentioned monitoring points is monitored, and the monitoring temperature of the monitoring points is obtained, and the temperature difference of each monitoring point on the same foot model is monitored, and the result of the temperature difference monitoring is compared with the preset value, and an evaluation result is obtained. Starting from the particularity of the main driver, the present application provides a thermal comfort evaluation method dedicated to the main driver, which accurately and comprehensively describes the thermal comfort of the main driver and can effectively avoid the problem of "yin and yang feet" in the left and right feet of the main driver.
