[0002] During the operation of engineering vehicles, the fuel tank cap intake valve plays a vital role. Its main function is to regulate the pressure in the fuel tank to ensure that the fuel can be smoothly supplied to the engine, while preventing the fuel tank from having too high or too low pressure, which affects the normal operation of the vehicle and the reliability of the fuel system.

[0003] With the continuous development of engineering vehicle technology and the increasing diversification of application scenarios, the performance requirements for the fuel tank cap intake valve are becoming higher and higher. Under different road conditions, the pressure in the fuel tank will be affected by many factors, such as the vehicle's driving posture (uphill, downhill), the flatness of the road surface (bumpy sections and smooth sections) and the driving speed. Changes in these factors will cause fluctuations in the pressure in the fuel tank, which requires the intake valve to be able to adjust the opening in a timely and accurate manner according to the actual situation to maintain the stability of the pressure in the fuel tank.

[0004] However, in actual applications, the fuel tank cap intake valve may have various problems, causing it to not work properly or its performance to deteriorate. For example, due to differences in manufacturing processes, wear or aging of components, and the influence of external environmental factors, the intake valve may not be able to adjust according to the preset opening requirements, thereby affecting the pressure balance of the fuel tank, which may further cause safety hazards such as poor fuel supply, engine performance degradation, and even fuel leakage.

DETAILED DESCRIPTION

[0018] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0019] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] Example 1 As mentioned in the background technology, the present application proposes a method for monitoring the intake valve of the fuel tank cap of an engineering vehicle, such as Figure 1 As shown, the following steps are included: S100. Obtaining a set of road section information of a preset journey, wherein the set of preset road section information includes preset road sections and preset road section information corresponding to each preset road section, wherein the preset road sections at least include an uphill road section, a downhill road section, a bumpy road section, and a smooth road section; Specifically, in certain infrastructure scenarios, before starting construction, the construction unit will use professional surveying and mapping tools to obtain road information of the road, including slope, bumpiness, flatness, roughness, etc., and will establish a road information database. The road section information set can be obtained based on the road information database, and can also be obtained through road information disclosed by municipal units.

[0021] S200. Obtaining a preset opening set of the intake valve according to the road section information set, wherein the preset opening set at least includes each of the preset road sections and a preset opening value of the intake valve corresponding to the preset road section; Specifically, during the operation of engineering vehicles, the control of the intake valve plays a vital role in the performance and fuel efficiency of the vehicle. For example, when an engineering vehicle passes through an uphill section, the opening of the intake valve will be increased to avoid insufficient air supply to the engine, which affects the power output and fuel efficiency. When passing through a downhill section, if the opening of the intake valve is not reduced, it will lead to risks such as engine overspeeding, power waste, increased burden on the braking system, and reduced vehicle stability. Therefore, there are currently a large number of studies on the control of the intake valve opening when the vehicle is traveling on special sections or smooth sections, wherein the special sections include uphill sections, downhill sections, bumpy sections, etc. That is, obtaining the preset opening value of the intake valve through preset section information is a current technology and will not be repeated here.

When the errors between the actual road section information and all parameters in the preset road section information satisfy the corresponding preset ranges, it is the first comparison result. When the error of any parameter is not within the corresponding preset range, it is the second comparison result.

[0024] S330. In response to the second comparison result, the preset section information of the current preset section is updated to the actual section information corresponding thereto, and the preset opening value corresponding to the current preset section is updated according to the actual section information, which is recorded as the first updated preset opening value; Among them, since the preset road section information is the information before the engineering vehicle travels to the road section, the road section information may change due to weather changes or the influence of multiple vehicles traveling. Therefore, the actual road section information is photographed by a camera, and the preset opening value of the intake valve is obtained according to the actual road section information, that is, the first updated preset opening value.

[0032] Specifically, before the engineering vehicle reaches each preset road section along the preset route, the preset road section information or updated preset road section information of each preset road section is obtained, and the preset opening value or the first updated preset opening value corresponding to each preset road section is obtained based on this information, and all the preset opening values ​​or the first updated preset opening values ​​are combined to obtain the preset opening update set; when the engineering vehicle completes the entire preset route, the actual opening value of the intake valve of each preset road section is obtained through the control system of the engineering vehicle, and all the actual opening values ​​are combined to obtain the actual opening set. After driving, the operating status of the intake valve is analyzed through the actual opening set and the preset opening update set, including the following steps: S421. Compare the actual opening set with the preset opening update set to obtain an abnormal opening value, wherein the abnormal opening value is the preset opening value or the actual opening value corresponding to the error between the first updated preset opening value and the actual opening value exceeding a preset threshold; like Figure 2 As shown, the solid circle represents the abnormal opening value, and the hollow circle represents the first updated preset opening value or the preset opening value; the preset threshold value is determined according to the actual situation of the engineering vehicle.

[0033] S422. When it is determined that the number of consecutive abnormal opening values ​​in the actual opening set is greater than a first preset number, a maintenance instruction is generated, wherein the maintenance instruction is used to prompt the driver to inspect the intake valve.

When the intake valve has problems for more than three consecutive times, it is determined that the intake valve needs to be inspected. During the inspection, first determine whether the intake valve needs to be replaced. If not, disassemble and repair it.
