Testing an engine under high idle speed conditions is primarily used to evaluate its operating status under different loads and ensure its performance meets standards.

[0003] In related technologies, the testing process for high-idle-speed engines typically relies on manual operation and sensory judgment, which is inefficient and prone to errors.

Detailed Implementation

[0018] Embodiments of the present disclosure will now be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the disclosure. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concepts of the present disclosure.

[0019] The accompanying drawings illustrate various structural schematics according to embodiments of the present disclosure. These drawings are not to scale, and some details have been enlarged for clarity, and some details may have been omitted. The shapes of the various regions and layers shown in the drawings, as well as their relative sizes and positional relationships, are merely exemplary and may deviate from reality due to manufacturing tolerances or technical limitations. Furthermore, those skilled in the art can design regions / layers with different shapes, sizes, and relative positions as needed.

[0020] In the context of this disclosure, when a layer / element is referred to as being "above" another layer / element, the layer / element may be directly above the other layer / element, or there may be an intermediate layer / element between them. Additionally, if a layer / element is "above" another layer / element in one orientation, then when the orientation is reversed, the layer / element may be "below" the other layer / element.

[0021] High-idle-speed engine testing is primarily used to evaluate the engine's operating status under different loads, ensuring its performance meets standards. It has the following significance: 1. Testing the engine's performance limits: By increasing the engine speed to a higher level (typically 50%-70% of the rated speed), its power output, stability, and emissions performance under high load can be observed. This helps to identify potential faults, such as insufficient power, abnormal vibration, or excessive emissions.

[0022] 2. Simulates real driving conditions: High-speed testing closely approximates the operating conditions of a vehicle at high speeds or during acceleration, providing a more comprehensive assessment of the engine's durability and adaptability. For example, high-speed scenarios that occasionally occur during daily driving (such as overtaking or climbing hills) are verified through testing, ensuring that the engine can still operate stably under extreme conditions.

[0023] 3. Optimize emission control: At high engine speeds, combustion is more complete, and exhaust gas data collected under these conditions more accurately reflects pollutant emission levels. For example, in the dual-idle speed test, the engine must first be accelerated to 70% of its rated speed and held for one minute to clean carbon deposits and ensure data validity.

[0024] 4. Verify factory standards Before mass production, automakers conduct high-intensity tests on engines (such as running at 7,000 rpm for 24 consecutive hours). The high-speed tests for annual vehicle inspections are similar in intensity to verify whether the vehicle meets safety and environmental protection requirements.

[0025] High idle speed testing of range-extended electric vehicles needs to be adjusted according to vehicle characteristics. In existing technologies, it usually relies on manual operation and human sensory judgment, such as manually observing whether the engine is running normally and whether there are fault lights on the instrument panel. This method is inefficient and prone to errors.

[0026] To address the aforementioned technical issues, some embodiments of this application, when the vehicle controller receives a high idle speed command while the range-extended vehicle is powered on, increase the speed of the range extender from its initial speed to a preset target speed within a preset time period, thus placing the range-extended vehicle in a high idle speed condition. The target speed is maintained for a preset detection time period, allowing a data acquisition unit to collect the operating parameters of the range-extended vehicle through a preset interface, encapsulate these parameters to obtain encapsulated parameters, and upload them to a server. The server then performs detection based on these encapsulated parameters to obtain the detection results. This application achieves automatic switching to high idle speed conditions in range-extended vehicles and enables efficient detection based on operating parameters even when the range-extended vehicle is stationary, effectively improving the efficiency and accuracy of vehicle detection and enhancing the user experience.

[0034] Optionally, the above operating parameters include at least one of the following: engine speed, water temperature, oil temperature, instantaneous fuel consumption, fan speed, sensor alarm status, system fault status, and oil circuit status.

[0035] This application embodiment, when the vehicle controller receives a high idle speed command while the range-extended vehicle is powered on, increases the speed of the range extender from its initial speed to a preset target speed within a preset time period, thus placing the range-extended vehicle in a high idle speed condition.

[0036] This application provides a method for detecting range-extended electric vehicles, such as... Figure 2 As shown, this method, which can be applied to data acquisition devices, includes: S201: When the range-extended vehicle is in a high idling condition, a preset interface is called to collect the operating parameters of the range-extended vehicle.

[0037] The aforementioned preset interface can be an international standard automotive communication interface (On-Board Diagnostics, ODB).

[0038] Optionally, a working condition switching button can be set in the central control system of the range-extended vehicle. The working condition switching button can be a physical button or a virtual button, and no specific limitation is made in this embodiment.

[0039] Furthermore, when the range-extended vehicle is powered on, the testing personnel can trigger the aforementioned operating condition switching button. The vehicle controller will receive a high idle speed command, causing the speed of the range extender in the range-extended vehicle to increase from the initial speed to the preset target speed within a preset time period, that is, the range-extended vehicle enters the high idle speed operating condition.

[0040] The preset duration can be 20 seconds or 22 seconds; the target speed can be determined based on the actual configuration of the engine; for example, for light vehicles, when the engine displacement is 1.5T, the target speed can be 2500 r / min; when the engine displacement is 2.0T, the target speed can be 3000 r / min.

[0041] Specifically, when the range-extended electric vehicle is in a high idling condition, the data acquisition unit can call the ODB interface to collect the operating parameters of the range-extended electric vehicle.

[0042] This application embodiment, when the vehicle controller receives a high idle speed command while the range-extended vehicle is powered on, increases the speed of the range extender from its initial speed to a preset target speed within a preset time period, thus placing the range-extended vehicle in a high idle speed condition. The target speed is maintained for a preset detection time period, allowing the data acquisition unit to collect the operating parameters of the range-extended vehicle through a preset interface, encapsulate these parameters to obtain encapsulated parameters, and upload them to a server. The server then performs detection based on these encapsulated parameters to obtain the detection results. This application achieves automatic switching to high idle speed conditions in range-extended vehicles and enables efficient detection based on operating parameters even when the range-extended vehicle is stationary, effectively improving the efficiency and accuracy of vehicle detection and enhancing the user experience.

[0043] This application provides a possible implementation method, wherein the above operating parameters include at least one of engine speed, water temperature, oil temperature, instantaneous fuel consumption, fan speed, sensor alarm status, system fault status, and oil circuit status.

[0046] Among them, the encapsulation parameters are obtained by the data acquisition unit based on the operating parameters; the operating parameters are obtained by the data acquisition unit when the range-extended vehicle is in a high idling condition by calling a preset interface.

[0047] Specifically, a working condition switching button can be preset in the central control system of the range-extended vehicle. When the range-extended vehicle is powered on, the tester can trigger the aforementioned working condition switching button. The vehicle controller will receive a high idle speed command, and the speed of the range extender of the range-extended vehicle will increase from the initial speed to the preset target speed within a preset time period, that is, the range-extended vehicle enters the high idle speed working condition.

[0048] The preset duration can be 20 seconds or 22 seconds; the target speed can be determined based on the actual configuration of the engine; for example, for light vehicles, when the engine displacement is 1.5T, the target speed can be 2500 r / min; when the engine displacement is 2.0T, the target speed can be 3000 r / min.

[0049] Furthermore, when the range-extended vehicle is in a high idling condition, the data acquisition unit can call the ODB interface to collect the operating parameters of the range-extended vehicle, encapsulate the operating parameters to obtain encapsulated parameters, and upload the encapsulated parameters to the server. The server receives the encapsulated parameters uploaded by the data acquisition unit.

[0050] The aforementioned operating parameters include at least one of the following: engine speed, water temperature, oil temperature, instantaneous fuel consumption, fan speed, sensor alarm status, system fault status, and oil circuit status.

[0051] S302, based on the packaging parameters, performs the detection and obtains the detection results.

[0052] Specifically, the server can decode and compare parameters of the encapsulated data to obtain the detection results. The specific detection steps will be described in detail below.

[0053] This application embodiment, when the vehicle controller receives a high idle speed command while the range-extended vehicle is powered on, increases the speed of the range extender from its initial speed to a preset target speed within a preset time period, thus placing the range-extended vehicle in a high idle speed condition. The target speed is maintained for a preset detection time period, allowing the data acquisition unit to collect the operating parameters of the range-extended vehicle through a preset interface, encapsulate these parameters to obtain encapsulated parameters, and upload them to a server. The server then performs detection based on these encapsulated parameters to obtain the detection results. This application achieves automatic switching to high idle speed conditions in range-extended vehicles and enables efficient detection based on operating parameters even when the range-extended vehicle is stationary, effectively improving the efficiency and accuracy of vehicle detection and enhancing the user experience.

[0054] This application provides a possible implementation method in which the detection based on encapsulation parameters is performed to obtain the detection result, including: The encapsulation parameters are decoded to obtain the operating parameters; the target parameters of the range-extended vehicle are obtained; and the detection results are determined based on the difference between the target parameters and the operating parameters.

[0055] This application provides a possible implementation method, wherein the data acquisition device includes a display device; After obtaining the detection results based on the packaging parameters, the results include: The test results are sent to the display device so that the display device can display the test results.

[0056] The aforementioned display device can be a display screen of a car's central control system or a user's mobile phone terminal, and is not specifically limited in this embodiment.

[0057] This application provides a possible implementation method whereby, after performing detection based on encapsulation parameters and obtaining the detection result, the following is included: Upload the running data and test results to the preset database.

[0058] In this embodiment, the server can upload operational data and detection results to a preset database, which facilitates subsequent problem tracing and querying, and further improves the user experience.

[0059] To better understand the above-mentioned testing methods for range-extended electric vehicles, the following will combine... Figure 4 A detailed example of a testing method for a range-extended electric vehicle according to this application is provided, the method comprising the following steps: S401, One-button entry of vehicle engine into high idle mode: When the vehicle is powered on, by clicking the preset one-button entry into high idle mode button on the vehicle's infotainment system, the engine system will enter high idle mode within 20 seconds and operate at a specific speed (based on the actual range extender's definition).

[0060] S402, Parameter and Function Check in High Idle Mode: Connect the dedicated equipment to the actual vehicle through the ODB port and start running the test program; the program automatically collects various parameters under high idle conditions (engine speed, water temperature, oil temperature, instantaneous fuel consumption, fan speed, alarm status of each sensor, system fault status, oil circuit status, etc.), and the execution time of high idle conditions is defined in combination with the actual needs of the range extender.

[0061] S403, High Idle Speed ​​Test Result Judgment and Output: Based on the parameters collected in S402, the data is processed by the preset system algorithm and judged against the preset standards and deviation values. If all parameters meet the standard range and there are no alarm states in the sensors and system, the evaluation test is passed, and the judgment result is displayed on the electronic screen (if the test is qualified, the vehicle can be transferred to the next work station), which makes it convenient for on-site personnel to obtain the inspection results; at the same time, it is uploaded to the vehicle manufacturing system for subsequent result query and traceability.

[0062] Specifically, such as Figure 4 The parameters described are the instantaneous fuel consumption, oil temperature, engine coolant temperature, and engine speed variation curves under high idling conditions. Upper and lower limits of the standard theoretical value range can be preset for each parameter, allowing users to determine the test results based on observations of the dotted line and comparisons with the standard theoretical value range. Figure 4 In the test, all the above parameters were within the standard theoretical value range, and the test results were all normal.

[0063] In some implementations, the above detection results may include multiple fault types. For example, the water temperature parameter may indicate a single fault type: water temperature too high; or parameters such as the operating status of the water pump / three-way valve and the operating status of the water temperature sensor may indicate a single fault type: water temperature too high. Furthermore, the monitored operating parameters showed that the engine coolant temperature was too high, and the engine automatically shut down after exceeding the threshold. However, there are several possible reasons for the high coolant temperature: 1. The water pump is not working / the three-way valve is damaged, causing the coolant to not circulate and resulting in heat dissipation failure; 2. The coolant temperature sensor is faulty, and the reported temperature data is incorrect. The root cause of the problem can be determined by analyzing each of these possible causes.

[0064] This application provides a range-extended vehicle detection system, such as... Figure 5 As shown, the system includes: The vehicle controller 501 is used to, when the range-extended vehicle is powered on, if a high idle speed command is received, increase the speed of the range extender from the initial speed to the preset target speed within a preset time period, and maintain the target speed within a preset detection time period.
