Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a vehicle control method, device, computer-readable storage medium, and vehicle. Background Technology

[0002] When an engine operates at low coolant temperatures (≤70℃) for extended periods, the gasoline mixed in the engine oil does not readily evaporate, resulting in a decrease in oil concentration—a phenomenon known as oil dilution. Furthermore, the application of direct injection technology (which easily wets the engine walls) and hybrid technology (which results in shorter engine operating times and slower coolant temperature rise) exacerbates the oil dilution problem.

[0003] Diluted engine oil will cause the oil level on the dipstick to rise, and excessively diluted engine oil can easily damage the engine, such as reducing engine life, reducing fuel economy, reducing power, and damaging the engine. Summary of the Invention

[0004] In view of this, the present invention aims to provide a vehicle control method, device, computer-readable storage medium, and vehicle to promptly reduce the oil dilution rate when the oil dilution rate is too high, thereby mitigating the damage to the engine caused by excessive oil dilution.

[0005] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0007] The vehicle's oil dilution rate is acquired in real time.

[0008] If the vehicle's oil dilution rate is increasing and the vehicle's current oil dilution rate is greater than or equal to a preset trigger threshold, then a first operation is performed to reduce the oil dilution rate.

[0009] If the current oil dilution rate of the vehicle is less than or equal to a preset release threshold, then a second operation is performed to release the first operation.

[0010] Wherein, the preset release threshold is less than the preset trigger threshold, and the difference between the preset trigger threshold and the preset release threshold belongs to a preset range.

[0011] Optionally, the preset trigger threshold includes a first trigger threshold, and the preset release threshold includes a first release threshold; if the vehicle's oil dilution rate is increasing, and the vehicle's current oil dilution rate is greater than or equal to the preset trigger threshold, then the first operation is performed, including:

[0012] If the vehicle's oil dilution rate is increasing and the vehicle's current oil dilution rate is greater than or equal to the first trigger threshold, then the vehicle enters a state adjustment mode to adjust the operating state of the vehicle's engine.

[0013] If the current oil dilution rate of the vehicle is less than or equal to a preset release threshold, then a second operation is performed, including:

[0014] If the current oil dilution rate of the vehicle is less than or equal to the first release threshold, then the state adjustment mode is exited.

[0015] Optionally, the operating state includes at least one of engine torque and engine speed.

[0016] Optionally, the preset trigger threshold includes a second trigger threshold, and the preset release threshold includes a second release threshold; if the vehicle's oil dilution rate is increasing, and the vehicle's current oil dilution rate is greater than or equal to the preset trigger threshold, then the first operation is performed, including:

[0017] If the vehicle's oil dilution rate is increasing and the vehicle's current oil dilution rate is greater than or equal to the second trigger threshold, then the vehicle's engine is controlled to enter maintenance mode to restrict the engine's start-stop function.

[0018] If the current oil dilution rate of the vehicle is less than or equal to a preset release threshold, then a second operation is performed, including:

[0019] If the current oil dilution rate of the vehicle is less than or equal to the second release threshold, then the maintenance mode is exited.

[0020] Optionally, the preset trigger threshold includes a third trigger threshold, and the preset release threshold includes a third release threshold; if the vehicle's oil dilution rate is increasing, and the vehicle's current oil dilution rate is greater than or equal to the preset trigger threshold, then the first operation is performed, including:

[0021] If the vehicle's oil dilution rate is increasing and the current oil dilution rate is greater than or equal to the third trigger threshold, a reminder message is generated and displayed to remind the vehicle's driver to change the oil.

[0022] If the current oil dilution rate of the vehicle is less than or equal to a preset release threshold, then a second operation is performed, including:

[0023] If the current oil dilution rate of the vehicle is less than or equal to the third release threshold, then the reminder message will stop being displayed.

[0024] Optionally, the difference between the preset trigger threshold and the preset release threshold falls within a preset range, including: the difference between the preset trigger threshold and the preset release threshold is greater than 0% and less than or equal to 5%.

[0025] Optionally, the real-time acquisition of the vehicle's oil dilution rate includes:

[0026] The system receives first information sent by the vehicle's engine controller in real time, the first information including the real-time operating status of the vehicle.

[0027] The vehicle's oil dilution rate is calculated based on the real-time operating status.

[0028] A second aspect of this application provides a vehicle control device, the device comprising:

[0029] The dilution rate acquisition module is used to acquire the engine oil dilution rate of the vehicle in real time.

[0030] The warning triggering module is used to perform a first operation if the oil dilution rate of the vehicle is increasing and the current oil dilution rate of the vehicle is greater than or equal to a preset trigger threshold. The first operation is used to reduce the oil dilution rate.

[0031] The warning cancellation module is used to perform a second operation if the current oil dilution rate of the vehicle is less than or equal to a preset cancellation threshold. The second operation is used to cancel the first operation.

[0032] Wherein, the preset release threshold is less than the preset trigger threshold, and the difference between the preset trigger threshold and the preset release threshold belongs to a preset range.

[0035] Compared with existing technologies, the vehicle control method of the present invention has the following advantages:

[0036] This invention provides a vehicle control method that acquires the vehicle's oil dilution rate in real time. If the vehicle's oil dilution rate is increasing and the current oil dilution rate is greater than or equal to a preset trigger threshold, a first operation is performed to reduce the oil dilution rate. If the vehicle's current oil dilution rate is less than or equal to a preset release threshold, a second operation is performed to release the first operation. This method effectively warns and responds to oil dilution rate issues, reducing engine damage caused by excessively high oil dilution rates. Furthermore, the difference between the preset release threshold and the preset trigger threshold falls within a preset range, avoiding repeated switching between the first and second operations, thus reducing the error rate and improving vehicle control stability.

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0045] The vehicle controller, also known as the powertrain controller, is the core control component of the entire vehicle system. It is primarily responsible for collecting signals from various vehicle components, such as accelerator pedal signals, brake pedal signals, and signals from other components. After making corresponding judgments based on the collected signals, it controls lower-level component controllers, such as the engine controller and the electric power steering system, to perform corresponding actions. Vehicle controllers mainly include the hybrid system vehicle controller (HCU) and the new energy vehicle controller (VCU).

[0046] The engine control unit (ECU) is primarily responsible for continuously monitoring and controlling the normal operation of the engine.

[0047] The engine's operating status, also known as the engine's working status, refers to the state of the engine when it is started, stopped (off), and operating under various loads, such as engine thrust, water temperature, torque, and speed.

[0048] The engine maintenance mode reduces the frequency of engine starts and stops, accelerates the rise in engine coolant temperature, and helps increase the rate of gasoline evaporation.

[0049] Reference Figure 1 The diagram shows a flowchart of an embodiment of a vehicle control method according to the present invention. The vehicle control method can be executed by the vehicle's own engine controller, vehicle controller, or other vehicle network, or it can be executed through external devices or networks. The present invention does not limit this.

[0050] The vehicle control method may include:

[0051] 101. Obtain the oil dilution rate of the vehicle in real time;

[0052] 102. If the oil dilution rate of the vehicle is increasing and the current oil dilution rate of the vehicle is greater than or equal to a preset trigger threshold, then a first operation is performed, the first operation being used to reduce the oil dilution rate.

[0053] 103. If the current oil dilution rate of the vehicle is less than or equal to a preset release threshold, then a second operation is performed, which is used to release the first operation;

[0054] Wherein, the preset release threshold is less than the preset trigger threshold, and the difference between the preset trigger threshold and the preset release threshold belongs to a preset range.

[0055] The preset trigger threshold is a warning threshold for when the oil dilution rate is high. When the oil dilution rate increases to the preset trigger threshold, a first operation can be performed to reduce the oil dilution rate. This first operation includes, but is not limited to, adjusting engine status, restricting engine start-stop, and providing oil change reminders. Different operations can be performed based on the increase in oil dilution rate, facilitating intelligent control for different oil dilution rates. For example, when the oil dilution rate is high but the damage to the engine is not severe (i.e., the oil dilution rate is 5%), the oil dilution rate can be reduced or the gasoline evaporation rate increased by adjusting the engine's operating status, thereby controlling the oil dilution rate.

[0056] Corresponding to the preset trigger threshold is the preset release threshold. When the oil dilution rate drops to or below the preset release threshold, the vehicle controller performs a second operation to release the first operation, thereby achieving flexible control of the dilution rate when it is too high.

[0057] Furthermore, the preset release threshold is less than the preset trigger threshold, and the difference between the preset trigger threshold and the preset release threshold falls within a preset range. The specific range can be determined based on the actual changes in the vehicle's oil dilution rate. When the oil dilution rate is high and unstable, the difference between the preset release threshold and the preset trigger threshold falling within the preset range avoids repeated switching between the first and second operations, thereby reducing the number of misoperations that may occur due to continuous switching. This helps reduce the error rate of the vehicle controller when performing operations related to reducing oil dilution rate, and improves the vehicle's control stability.

[0058] Regarding step 101, in this embodiment of the invention, the oil dilution rate can be obtained in real time by periodically querying the engine controller, sensors, and other devices at specific time intervals; alternatively, the oil dilution rate can be obtained in real time from the engine controller, sensors, and other devices through a subscription method. Of course, the engine's operating status can also be obtained in real time using the above methods, and the vehicle's real-time oil dilution rate can be calculated based on the operating status; the present invention does not limit this to any of these methods.

[0059] Optionally, the preset trigger threshold includes a first trigger threshold, and the preset release threshold includes a first release threshold; step 102, if the vehicle's oil dilution rate is increasing and the vehicle's current oil dilution rate is greater than or equal to the preset trigger threshold, then the first operation is performed, including:

[0060] S11. If the oil dilution rate of the vehicle is increasing and the current oil dilution rate of the vehicle is greater than or equal to the first trigger threshold, then enter the state adjustment mode to adjust the operating state of the vehicle's engine.

[0061] Step 103 states that if the current oil dilution rate of the vehicle is less than or equal to a preset release threshold, then a second operation is performed, including:

[0062] S21. If the current oil dilution rate of the vehicle is less than or equal to the first release threshold, then exit the state adjustment mode.

[0063] Considering that the damage caused by oil dilution to the engine and vehicle varies depending on the oil dilution rate, the vehicle controller can perform different operations based on the current oil dilution rate when reducing the oil dilution rate.

[0064] The first release threshold is less than the first trigger threshold. The first release threshold and the first trigger threshold can be used as the warning triggering condition and warning release condition when the damage to the engine from oil dilution is minor, and can be set according to the actual situation of the vehicle.

[0065] Because the oil dilution rate and gasoline evaporation rate differ depending on the engine's operating state—for example, at higher engine speeds, gasoline more readily enters the oil, resulting in a faster oil dilution rate—the vehicle can enter a state adjustment mode when the current oil dilution rate is greater than or equal to a first trigger threshold. This mode controls and reduces the oil dilution rate by adjusting the engine's operating state, such as adjusting the intake air volume and engine speed. When the current oil dilution rate drops below or equal to a first release threshold, the vehicle controller can exit the state adjustment mode.

[0066] Taking a vehicle controller as an example, when the coolant temperature is low, the controller can limit engine operating conditions such as speed and torque to reduce the rate at which gasoline mixes with the engine oil, thus reducing the oil dilution rate. This prevents excessive oil dilution before the engine coolant temperature rises to a certain level. When the coolant temperature is high, the gasoline evaporation rate is faster. Therefore, the controller can adjust engine operating conditions such as intake air volume and speed to increase the gasoline evaporation rate, thereby reducing the oil dilution rate. Here, the gasoline evaporation rate refers to the rate at which gasoline mixed with the engine oil evaporates.

[0067] By adjusting the engine's operating conditions to reduce the oil dilution rate, the increase in oil dilution rate can be effectively limited when the damage caused by oil dilution to the engine is relatively minor, thus preventing unpredictable damage to the engine caused by excessive oil dilution.

[0068] Optionally, the operating state includes at least one of engine torque and engine speed.

[0069] Torque and speed can accurately reflect the engine's operating status. Therefore, by controlling engine torque and speed alone, the oil dilution rate can be controlled, which helps simplify the complex analysis process of engine operating status and saves computing resources of the vehicle network.

[0070] Optionally, the preset trigger threshold includes a second trigger threshold, and the preset release threshold includes a second release threshold; step 102, if the vehicle's oil dilution rate is increasing and the vehicle's current oil dilution rate is greater than or equal to the preset trigger threshold, then the first operation is performed, including:

[0071] S31. If the oil dilution rate of the vehicle is increasing and the current oil dilution rate of the vehicle is greater than or equal to the second trigger threshold, then the engine of the vehicle is controlled to enter maintenance mode to restrict the start and stop of the engine.

[0072] Step 103 states that if the current oil dilution rate of the vehicle is less than or equal to a preset release threshold, then a second operation is performed, including:

[0073] S41. If the current oil dilution rate of the vehicle is less than or equal to the second release threshold, then exit the maintenance mode.

[0074] The second release threshold is lower than the second trigger threshold. The second release threshold and the second trigger threshold can serve as the warning trigger and warning release conditions for situations where oil dilution causes significant engine damage, and can be set according to the actual conditions of the vehicle.

[0075] When the oil dilution rate is greater than or equal to the second trigger threshold, the engine can be controlled to enter maintenance mode to restrict engine start-stop, allowing the engine to run continuously and promoting the rise of engine coolant temperature, thereby increasing the gasoline evaporation rate and reducing the oil dilution rate. When the oil dilution rate drops to less than or equal to the second release threshold, maintenance mode can be exited.

[0076] Compared to reducing oil dilution by adjusting engine operating conditions, reducing oil dilution by limiting engine start-stop can quickly achieve gasoline evaporation, thereby reducing oil dilution. This helps to stop the damage to the engine caused by oil dilution in time when it becomes severe, thus protecting the engine.

[0077] Optionally, the preset trigger threshold includes a third trigger threshold, and the preset release threshold includes a third release threshold; step 102 states that if the vehicle's oil dilution rate is increasing, and the vehicle's current oil dilution rate is greater than or equal to the preset trigger threshold, then the first operation is performed, including:

[0078] S51. If the vehicle's oil dilution rate is increasing and the vehicle's current oil dilution rate is greater than or equal to the third trigger threshold, a reminder message is generated and displayed. The reminder message is used to remind the vehicle's driver to change the oil.

[0079] Step 103 states that if the current oil dilution rate of the vehicle is less than or equal to a preset release threshold, then a second operation is performed, including:

[0080] S61. If the current oil dilution rate of the vehicle is less than or equal to the third release threshold, then stop displaying the reminder message.

[0081] The third release threshold is lower than the third trigger threshold. The third release threshold and the third trigger threshold can be used as the warning trigger and warning release conditions when the engine oil needs changing, and can be set according to the actual situation of the vehicle.

[0082] If the vehicle's current oil dilution rate exceeds a third threshold, a reminder message can be generated and displayed to remind the driver to change the oil. For example, the vehicle controller can generate a reminder message and display it on the vehicle's dashboard to remind the driver to change the oil; alternatively, it can display a client connected to the vehicle's network, etc., which is not limited in this invention. When the vehicle's oil dilution rate drops to less than or equal to the third release threshold, the vehicle controller can stop displaying the reminder message.

[0083] Optionally, the first trigger threshold is less than the second trigger threshold and less than the third trigger threshold; the first release threshold is less than the second release threshold and less than the third release threshold.

[0084] Different degrees of oil dilution can cause varying degrees of damage to the engine. Therefore, different methods are needed to reduce the oil dilution rate when the oil dilution rate varies. In this case, the three preset trigger thresholds mentioned above can serve as warning trigger conditions when the oil dilution rate reaches different levels, and correspondingly, the three preset release thresholds can serve as warning release conditions when the oil dilution rate decreases.

[0085] Specifically, during the increase of oil dilution rate, when the oil dilution rate is greater than or equal to the first trigger threshold, the oil dilution rate can be reduced by adjusting the engine operating state. When the oil dilution rate is greater than or equal to the second trigger threshold, adjusting the engine operating state may not be effective in controlling the oil dilution rate. In this case, the engine can be put into maintenance mode, and the oil dilution rate can be reduced by limiting the engine start-stop function. When the oil dilution rate is greater than or equal to the third trigger threshold, the oil dilution phenomenon is too severe. A reminder message can be generated to remind the driver to change the oil, thus avoiding excessive damage to the engine caused by oil dilution.

[0086] Accordingly, during the process of decreasing oil dilution rate, if the oil dilution rate is less than or equal to the third release threshold, it indicates that the oil dilution phenomenon has not yet reached the point where oil replacement is required. In this case, the reminder message will stop being displayed, and the engine will be controlled to enter maintenance mode based on the second trigger threshold. If the oil dilution rate is less than or equal to the second release threshold, the engine maintenance mode will be exited, and the engine operating status will be adjusted based on the first trigger threshold. If the oil dilution rate is less than or equal to the third release threshold, it indicates that the oil dilution rate is within the normal range, and the engine will be restored to normal operating status.

[0087] By employing the above methods, corresponding measures are taken to address different degrees of oil dilution, achieving reasonable control of the oil dilution rate and reducing the damage caused by oil dilution to the engine. Of course, the preset trigger thresholds and preset release thresholds, along with their corresponding specific processing methods, can be combined and set according to the actual conditions of the vehicle. For example, the value of the first trigger threshold may fall within the range between the first and second release thresholds, and the value of the second trigger threshold may fall within the range between the second and third release thresholds. This invention does not limit the specifics of these settings.

[0088] Optionally, the difference between the preset trigger threshold and the preset release threshold falls within a preset range, including: the difference between the preset trigger threshold and the preset release threshold is greater than 0% and less than or equal to 5%.

[0089] Based on the aforementioned preset range, the frequency of operation switching by the vehicle controller during the dilution rate reduction operation can be reduced, thus avoiding increased error rate due to frequent switching.

[0090] Optionally, step 101, which involves obtaining the vehicle's oil dilution rate in real time, includes:

[0091] S71. Receive first information sent by the engine controller of the vehicle in real time, the first information including the real-time operating status of the vehicle;

[0092] S72. Calculate the oil dilution rate of the vehicle based on the real-time operating status.

[0093] It's understandable that different oil dilution ratios will have different effects on engine operating conditions. For example, engine speed, torque, and intake air volume are all affected by the oil dilution ratio, which is also affected by engine operating time. Therefore, by using different engine operating data and corresponding oil dilution ratio data, a predictive model for calculating oil dilution ratio can be built, taking engine operating status and operating time as input and oil dilution ratio as output, and then writing the predictive model into the HCU. After the HCU obtains the engine operating status feedback from the ECU, it can then use the predictive model to calculate the oil dilution ratio.

[0094] To ensure real-time acquisition of the engine oil dilution rate, the engine operating status also needs to be acquired in real time. Therefore, the ECU can periodically access sensors to obtain the engine's real-time operating status. Similarly, the HCU can periodically send information requests to the ECU; or, a subscription mechanism can be established between the HCU and the ECU, so that when the ECU detects a change in the engine operating status, it can immediately feed back the changed engine operating status to the HCU. By acquiring the engine's real-time operating status, the HCU can calculate the engine's real-time oil dilution rate using a predictive model.

[0095] Reference Figure 2 The diagram illustrates a flowchart of an embodiment of the dilution rate calculation method of the present invention. The prediction model takes engine coolant temperature, operating time, engine speed, and torque as inputs and engine oil dilution rate as output. The ECU can acquire engine coolant temperature, engine speed, and torque in real time through various sensors and feed them back to the HCU. After the HCU receives the real-time feedback of engine coolant temperature, engine speed, and torque from the ECU, it can calculate the engine oil dilution rate implemented by the vehicle using the prediction model, combined with the engine operating time.

[0096] By using the above method, the oil dilution rate can be monitored and controlled without adding an oil level sensor, thus reducing the manufacturing and maintenance costs of the vehicle.

[0097] Reference Figure 3 The diagram illustrates a flowchart of another embodiment of the vehicle control method of the present invention. The first trigger threshold can be 5%, the second trigger threshold can be 10%, and the third trigger threshold can be 15%, with the order of first release threshold < first trigger threshold < second release threshold < second trigger threshold < third release threshold < third trigger threshold. After the engine starts, the vehicle controller executes the method described in steps S71-S72 above, using a predictive model to calculate the vehicle's oil dilution rate in real time.

[0098] During the oil dilution process, if the vehicle's oil dilution rate is greater than or equal to the first trigger threshold, the engine's operating state is adjusted to reduce the oil dilution rate, as described in step S11 above. If the vehicle's oil dilution rate is greater than or equal to the second trigger threshold, the engine is controlled to enter maintenance mode, limiting engine start-stop, to increase the gasoline evaporation rate and reduce the oil dilution rate, as described in step S31 above. If the vehicle's oil dilution rate is greater than or equal to the third trigger threshold, the malfunction indicator lamp is illuminated, as described in step S51 above, to remind the driver to change the oil.

[0099] During the process of oil dilution reduction (i.e., evaporation), if the vehicle's oil dilution rate is less than or equal to the third release threshold, the malfunction indicator lamp is turned off according to the method described in step S61 above. If the vehicle's oil dilution rate is less than or equal to the second release threshold, the engine is controlled to exit the maintenance model according to the method described in step S41 above. If the vehicle's oil dilution rate is less than or equal to the first release threshold, the engine's operating state adjustment is stopped according to the method described in step S21 above, and the engine is controlled to resume normal operation.

[0100] In summary, this invention provides a vehicle control method that acquires the vehicle's oil dilution rate in real time. If the vehicle's oil dilution rate is increasing and the current oil dilution rate is greater than or equal to a preset trigger threshold, a first operation is performed to reduce the oil dilution rate. If the vehicle's current oil dilution rate is less than or equal to a preset release threshold, a second operation is performed to release the first operation. This method effectively warns and responds to oil dilution rate issues, mitigating engine damage caused by excessively high oil dilution rates. Furthermore, the difference between the preset release threshold and the preset trigger threshold falls within a preset range, avoiding repeated switching between the first and second operations, thus reducing the error rate and improving vehicle control stability.
