Description

Technical Field

[0001] The present application relates to the field of vehicles, and in particular, to a vehicle management method and a vehicle management system. Background Art

[0002] In the related art, the judgment mode for vehicle faults is mainly offline. Technicians preset fault items in advance according to regulations or experience, calibrate fault thresholds based on the fault items, and then write these thresholds into relevant controllers such as EMS, PMS, and BMS. When the fault threshold is reached, relevant fault lights are displayed on the instrument to achieve the purpose of reminding and warning.

[0003] However, this method has many limitations: 1. This fault alarm method is offline. When a fault occurs, only the user can know that there is a fault in the vehicle, and developers and after-sales personnel cannot be informed in a timely manner; 2. The types of vehicle faults are complex, and the limited fault lights on the instrument cannot clearly reflect the fault information; 3. Some simple initial faults cannot be processed and investigated in a timely manner, usually causing larger faults and resulting in great losses; 4. It is difficult to set reasonable thresholds. If the thresholds are set strictly, the fault frequency is high, which is likely to affect the user experience. If the thresholds are set loosely, it will cause direct damage to system components; 5. The threshold parameters set by the client cannot be adjusted in real time, and the flexibility is poor. Summary of the Invention

Detailed implementation manners

When the following description involves the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only for the purpose of convenient description and cannot be understood as indicating or implying relative importance.

[0099] The present application provides a vehicle management method and a vehicle management system 100. Hereinafter, in conjunction with the accompanying drawings, the vehicle management method and the vehicle management system 100 of the present application will be described in detail. Without conflict, the features in the following embodiments and embodiments can be combined with each other.

[0100] The present application provides a vehicle management method, as shown in Figure 1 shown, including step S10, step S20, and step S30.

[0101] In step S10, vehicle monitoring data is acquired.

[0102] In step S20, the vehicle monitoring data is parsed to obtain a parsing result.

[0103] In step S30, an operation is performed according to the parsing result.

[0104] Among them, in step S30, performing an operation according to the parsing result includes step S31. In step S31, when there is a risk in the parsing result, a warning message is sent to the target terminal 130.

[0105] Through the above settings, by acquiring and parsing vehicle monitoring data, instead of the fixed setting of the vehicle fault threshold, it can be adjusted according to vehicle types, etc., and the fault items that need to be warned can be increased or decreased in real time, and parsed according to different working conditions, different environments, etc., and the vehicle management strategy can be optimized and adjusted in a timely manner; at the same time, by sending a warning about the risks existing in the vehicle to the target terminal 130, it can play a warning role for one or more target terminals 130, which is conducive to information communication between the target terminals 130.

[0106] In an alternative embodiment, the vehicle includes a methanol range extender. The vehicle monitoring data includes range extender monitoring data. The target terminal 130 includes a vehicle terminal 131 and a fueling point terminal 132 connected to the vehicle.

[0107] Referring to Figure 2 As shown, in step S10, vehicle monitoring data is acquired, including step S11. In step S11, range extender monitoring data is acquired.

[0108] In step S31, when the parsing result is risky, a warning message is sent to the target terminal 130, including step S311. In step S311, when the parsing result is risky, a warning message is sent to the vehicle terminal 131 and the fueling point terminal 132.

[0109] By setting up a methanol range extender, the vehicle with methanol fuel and a pure electric system is organically combined. Utilizing the high energy density and long driving range advantages of methanol fuel, the mileage anxiety problem of vehicles with a pure electric system is solved; on the other hand, the economic and environmental protection advantages of the pure electric system can be fully utilized to obtain the economy and road rights of pure electric models.

[0110] By acquiring range extender monitoring data, the operating status and health of the methanol range extender are analyzed, and early warnings are given for possible risks of the methanol range extender. When there are risks in the methanol range extender, a warning is sent to the vehicle terminal 131 and the fueling point terminal 132, which can play a warning role for the vehicle terminal 131 and the fueling point terminal 132, and helps the fueling point terminal 132 timely learn about the methanol quality status, so that inspections and adjustments can be made in a timely manner, which is conducive to information communication between the vehicle terminal 131 and the fueling point terminal 132.

[0111] In an alternative embodiment, the range extender monitoring data includes a vehicle speed signal, a methanol liquid level signal, and a methanol quality signal. Referring to Figure 3 As shown, in step S11, range extender monitoring data is acquired, including step S111 and step S112.

[0112] In step S111, the vehicle speed signal and the methanol liquid level signal are acquired.

[0113] In step S112, when the vehicle speed signal is 0 and the methanol liquid level signal increases, the methanol quality signal is acquired.

[0114] In step S311, when the parsing result is risky, a warning message is sent to the vehicle terminal 131 and the fueling point terminal 132, including step S3111 and step S3112.

[0115] In step S3111, when the methanol quality signal is greater than or equal to the first methanol quality set value, a methanol quality warning message is sent to the vehicle terminal 131 and the filling point terminal 132.

[0116] In step S3112, when the methanol quality signal is less than the first methanol quality set value, a methanol quality safety message is sent to the vehicle terminal 131.

[0117] When the vehicle speed signal is 0 and the methanol level signal increases, the vehicle is being filled with methanol. At this time, the methanol quality signal obtained is affected by the methanol quality at the filling point. When the methanol quality signal is less than the first methanol quality set value, the methanol quality at the filling point is safe, and a methanol quality safety message is sent to the vehicle terminal 131, where the vehicle terminal 131 includes the vehicle terminal 131 being filled at this filling point and other vehicle terminals 131 waiting to be filled. Specifically, the filling point with safe methanol quality can be marked green on the user's mobile phone. When the methanol quality signal is greater than or equal to the first methanol quality set value, there is a problem with the methanol quality at the filling point, and a methanol quality warning message is sent to the vehicle terminal 131 and the filling point terminal 132, where the vehicle terminal 131 includes the vehicle terminal 131 being filled at this filling point and other vehicle terminals 131 waiting to be filled. Specifically, the filling point with safe methanol quality can be marked orange on the user's mobile phone, that is, to distinguish it from the filling point with safe methanol quality.

[0118] Through the above settings, by monitoring the methanol quality during vehicle filling, the methanol quality at the filling point can be monitored in real time. When there is a problem with the methanol quality at the filling point, it can be discovered in time and other users can be informed, thus facilitating the monitoring of the methanol quality at the filling point and reducing the filling of methanol with problems by other vehicles, which is beneficial to the driving safety of vehicles equipped with methanol range extenders, controlling the methanol quality provided by the filling point, and improving the user experience.

[0119] In an alternative embodiment, referring to Figure 4 as shown, in step S3111, when the methanol quality signal is greater than or equal to the first methanol quality set value, sending a methanol quality warning message to the vehicle terminal 131 and the filling point terminal 132 includes steps S3113, S3114, and S3115.

[0120] In step S3113, when the methanol quality is greater than or equal to the first methanol quality set value and less than the second methanol quality set value, a methanol quality inspection message is sent to the filling point terminal 132.

[0121] In step S3114, when the methanol quality is greater than or equal to the second methanol quality set value and less than the third methanol quality set value, a methanol filling amount reduction instruction is sent to the filling point terminal 132.

[0122] In step S3115, when the methanol quality is greater than or equal to the third methanol quality set value, a methanol filling stop instruction is sent to the filling point terminal 132.

[0123] When the methanol quality is greater than or equal to the first methanol quality set value and less than the second methanol quality set value, the methanol quality has a slight abnormality. A methanol quality inspection information is sent to the filling point terminal 132, indicating that the filling point terminal 132 inspects the methanol quality. When the methanol quality is greater than or equal to the first methanol quality set value and less than the second methanol quality set value, the methanol quality has a relatively serious abnormality. A methanol filling amount reduction instruction is sent to the filling point terminal 132, indicating that the filling point terminal 132 reduces the filling amount of the vehicle to reduce the risk of methanol range extender failure caused by methanol with quality problems. When the methanol quality is greater than or equal to the third methanol quality set value, the methanol quality has a serious abnormality. A methanol filling stop instruction is sent to the filling point terminal 132 to avoid methanol range extender failure caused by methanol with serious quality problems.

[0124] Through the above settings, different degrees of abnormalities in methanol quality are respectively prompted to the filling point and the vehicle terminal 131. When there is a problem with the methanol quality at the filling point, it can be discovered in time and other users can be informed, thus facilitating the monitoring of the methanol quality at the filling point and reducing the filling of methanol with problems by other vehicles, which is beneficial to the driving safety of vehicles equipped with methanol range extenders, controls the methanol quality provided by the filling point, and improves the user experience.

[0125] Specifically, when the methanol quality is greater than or equal to the second methanol quality set value and less than the third methanol quality set value, a methanol quality warning information can also be sent to the vehicle terminal 131. For example, the filling points with safe methanol quality can be marked in orange on the user's mobile phone, that is, distinguished from the filling points with safe methanol quality. When the methanol quality is greater than or equal to the third methanol quality set value, a methanol quality warning information can also be sent to the vehicle terminal 131. For example, the filling points with safe methanol quality can be marked in red on the user's mobile phone to remind the user that methanol filling cannot be carried out at the current filling point.

[0126] In an alternative embodiment, referring to Figure 5 as shown, after step S3111, when the methanol quality signal is greater than or equal to the first methanol quality set value and a methanol quality warning information is sent to the vehicle terminal 131 and the filling point terminal 132, it includes step S3116 and step S3117.

[0127] In step S3116, when the methanol quality signal is greater than or equal to the first methanol quality set value, a first count is performed on the filling point.

[0128] In step S3117, when the first count corresponding to the fueling point reaches the set first set count, a methanol quality inspection message is sent to the fueling point terminal 132.

[0129] Through the above settings, it is beneficial for the fueling point to be able to promptly detect abnormal methanol quality, so as to reduce the risk of methanol quality problems causing methanol range extender failures.

[0130] Specifically, when the methanol quality is greater than or equal to the first methanol quality set value and less than the second methanol quality set value, the first count is performed on the fueling point, increasing the first count value corresponding to the fueling point by 1. When the first count value of the fueling point reaches 10, a methanol quality inspection message is sent to the fueling point terminal 132, indicating to the fueling point terminal 132 to inspect the methanol quality.

[0131] When the methanol quality is greater than or equal to the second methanol quality set value and less than the third methanol quality set value, the third count is performed on the fueling point, increasing the third count value corresponding to the fueling point by 1. When the third count value of the fueling point reaches 2, a methanol quality inspection message is sent to the fueling point terminal 132, indicating to the fueling point terminal 132 to inspect the methanol quality.

[0132] Through the above settings, for different degrees of abnormalities in methanol quality, the fueling point is counted separately, which is beneficial for the fueling point to be able to promptly detect abnormal methanol quality, and count separately according to different degrees of abnormalities, so as to reduce the risk of methanol quality problems causing methanol range extender failures, and at the same time reduce the frequency of inspecting the methanol quality at the fueling point caused by minor abnormalities.

[0133] In an alternative embodiment, referring to Figure 6 As shown, step S3117, when the first count corresponding to the fueling point reaches the first set count, sending a methanol quality inspection message to the fueling point terminal 132 includes step S3118 and step S3119.

[0134] In step S3118, when the inspection result of the fueling point shows that the methanol quality is less than the first methanol quality set value, the second count is performed on the fueling point.

[0135] In step S3119, when the second count corresponding to the fueling point reaches the set second set count, a methanol quality safety message is sent to the vehicle terminal 131.

[0136] Specifically, when the inspection result of the refueling point shows that the methanol quality is less than the first methanol quality set value, a second count is performed on the refueling point, so that the second count value corresponding to the refueling point is incremented by 1. After the second count value of the refueling point reaches 2, a methanol quality safety message is sent to the vehicle terminal 131, where the vehicle terminal 131 includes the vehicle terminal 131 that is refueling at this refueling point and other vehicle terminals 131 waiting to be refueled. For example, the refueling point with methanol quality safety can be marked as green on the user's mobile phone.

[0137] Through the above settings, the methanol quality safety of the refueling point is determined through continuous multiple detection results, reducing the risk of detection errors, ensuring the safety of the methanol quality being refueled, facilitating the driving safety of vehicles equipped with methanol range extenders, controlling the methanol quality provided at the refueling point, and enhancing the user experience.

[0138] In an alternative embodiment, the vehicle monitoring data includes a motor temperature signal. The target terminal 130 includes the vehicle terminal 131 and the maintenance point terminal 133.

[0139] See Figure 7 As shown, step S10 of obtaining vehicle monitoring data includes step S12. In step S12, a motor temperature signal is obtained.

[0140] Step S30 of performing an operation according to the parsing result and obtaining the parsing result includes step S32.

[0141] In step S32, when the motor temperature signal is greater than the set motor temperature, a motor over-temperature analysis is triggered.

[0142] Step S31 of sending a warning message to the target terminal 130 when the parsing result is risky includes step S312.

[0143] In step S312, according to the motor over-temperature analysis, a warning message is sent to the vehicle terminal 131 and the maintenance point terminal 133.

[0144] Through the motor over-temperature analysis, a warning message is sent to the vehicle terminal 131 and the maintenance point terminal 133, preventing the vehicle from losing power after the motor overheats and being able to promptly inform the maintenance point for repair, facilitating the driving safety of the vehicle, reminding the maintenance point to make repair preparations or ensuring that the maintenance point can provide repair services, thereby enhancing the user experience.

[0145] In an alternative embodiment, see Figure 8 As shown, step S32 of triggering a motor over-temperature analysis when the motor temperature signal is greater than the set motor temperature includes step S321, step S322, and step S323.

[0146] In step S321, a vehicle identification code is obtained.

[0147] In step S322, vehicle boundary data is obtained according to the vehicle identification number. The vehicle boundary data includes at least one of the maximum load, maximum vehicle speed, maximum climbing gradient, maximum output power of the drive motor, and maximum allowable operating temperature of the drive motor.

[0148] In step S323, motor over-temperature analysis is performed based on the vehicle boundary data;

[0149] Step S312 sends a warning message to the vehicle terminal 131 and the maintenance point terminal 133 according to the motor over-temperature analysis, including step S3121 and step S3122.

[0150] In step S3121, when the result of the motor over-temperature analysis indicates that there is an overloading problem with the vehicle, a warning message is sent to the vehicle terminal 131.

[0151] In step S3122, when the result of the motor over-temperature analysis indicates that there is no overloading problem with the vehicle, a warning message is sent to the vehicle terminal 131 and the maintenance point terminal 133.

[0152] Specifically, when the result of the motor over-temperature analysis shows that the motor over-temperature of the vehicle is caused by overloading and long-time uphill driving, etc., a warning message is sent to the vehicle terminal 131, suggesting that the user reduce the vehicle speed or gently step on the accelerator pedal to relieve the motor over-temperature problem, avoid loss of power after the drive motor overheats, thereby reducing the risk of causing safety hazards and being beneficial to the driving safety of the vehicle. When the result of the motor over-temperature analysis shows that there is no overloading problem with the vehicle, it indicates that the vehicle's working state is abnormal. A warning message is sent to the vehicle terminal 131 and the maintenance point terminal 133. Specifically, it can trigger a service reminder at the maintenance point, inform the user that the vehicle has an abnormal working state, and inform the user of the location of the nearest maintenance point, thereby realizing the rapid repair of the vehicle, being beneficial to the driving safety of the vehicle, and improving the user experience.

[0153] In an alternative embodiment, the vehicle monitoring data includes at least one of a vehicle positioning signal, a load signal, a battery power signal, a battery current signal, a vehicle speed signal, a brake pedal opening degree signal, and a gradient signal.

[0154] See Figure 9 As shown, in step S20, the vehicle monitoring data is parsed to obtain a parsing result, including step S21.

[0155] In step S21, the vehicle monitoring data is parsed, and the highest pre-temperature of the vehicle's brake operation is obtained.

[0156] In step S30, an operation is performed according to the parsing result, including step S33.

[0157] In step S33, when the highest pre-temperature is greater than or equal to the first set highest temperature, a warning message is sent to the vehicle terminal 131.

[0158] By obtaining the highest pre-temperature of the vehicle, when the highest pre-temperature is greater than or equal to the first set highest temperature, the vehicle has a risk of stalling. Sending a warning message to the vehicle terminal 131 can warn the user, thereby reducing risks such as vehicle stalling and brake failure, which is beneficial to the driving safety of the vehicle and improves the user experience.

[0159] In an alternative embodiment, referring to Figure 10 As shown, step S33, when the highest pre-temperature is greater than or equal to the first set highest temperature, sending a warning message to the vehicle terminal 131 further includes steps S331, S332, and S333.

[0160] In step S331, when the highest pre-temperature is greater than or equal to the first set highest temperature and less than the second set highest temperature, a first-level warning message is sent to the vehicle terminal 131, and the first-level warning message includes a text warning message.

[0161] In step S332, when the highest pre-temperature is greater than or equal to the second set highest temperature and less than the third set highest temperature, a second-level warning message is sent to the vehicle terminal 131, and the second-level warning message includes an audible warning message.

[0162] In step S333, when the highest pre-temperature is greater than or equal to the third set highest temperature, a third-level warning message is sent to the vehicle terminal 131, and the third-level warning message includes a manual phone warning message.

[0163] When the highest pre-temperature is greater than or equal to the first set highest temperature and less than the second warning message, a first-level warning message is sent to the vehicle terminal 131. The first-level warning message includes a text warning message. For example, the user is reminded by text message that there is a risk of vehicle stall. The information content includes the recommended parking and cooling locations on this section of the road, driving suggestions to avoid brake failure, the location most likely to cause stall, and other information. When the highest pre-temperature is greater than or equal to the second set highest temperature and less than the third set highest temperature, a second-level warning message is sent to the vehicle terminal 131. The second-level warning message includes an audible warning message. For example, the user is reminded by text message that there is a risk of vehicle stall. The information content includes the recommended parking and cooling locations on this section of the road, driving suggestions to avoid brake failure, the location most likely to cause stall, and other information. At the same time, an intelligent voice reminder is made by phone to inform the user of the stall risk. When the highest pre-temperature is greater than or equal to the third set highest temperature, a third-level warning message is sent to the vehicle terminal 131. The third-level warning message includes a manual phone warning message. For example, the user is reminded by text message that there is a risk of vehicle stall. The information content includes the recommended parking and cooling locations on this section of the road, driving suggestions to avoid brake failure, the location most likely to cause stall, and other information. At the same time, a reminder is made by manual phone to inform the user of the stall risk.

[0164] Through the above settings, the possible risk situations of the vehicle during operation are judged according to the highest pre-temperature of the vehicle brake, and different levels of reminders are adopted for different degrees of risks, which is beneficial to the driving safety of the vehicle and improves the user experience.

[0165] In an optional embodiment, the target terminal 130 includes a development terminal 134. The vehicle monitoring data includes at least one of a battery power signal, a battery current signal, a battery voltage signal, a vehicle speed signal, a brake pedal opening degree signal, a slope signal, a transmission gear signal, and an extender current signal.

[0166] Step S30, perform an operation according to the parsing result, including step S34.

[0167] In step S34, when the battery current signal is greater than or equal to the maximum allowable feedback current of the vehicle battery and the duration exceeds the first set duration, a warning message is sent to the development terminal 134.

[0168] Specifically, when the ratio of the battery current signal to the maximum allowable feedback current of the vehicle's battery is between 1.2 and 1.5 and the duration exceeds 0.5 seconds; or when the ratio of the battery current signal to the maximum allowable feedback current of the vehicle's battery exceeds 1.5 and the duration exceeds 0.2 seconds, a warning message is sent to the development terminal 134, and the development personnel evaluate whether the relevant strategies of the vehicle's system are in the optimal state and optimize the suboptimal parts. If it is considered that there are indeed unreasonable parts in the vehicle's overall strategy, the development personnel optimize the unreasonable strategies. After the optimization is completed, a software upgrade package is generated and released to the vehicle terminal 131 through OTA. Thus, during the use of the vehicle, the problems of the vehicle's overall strategy can be discovered in a timely manner and optimized in a timely manner, which is beneficial to the driving safety of the vehicle and improves the user experience.

[0169] The present application also provides a vehicle management system 100. Refer to Figure 11 As shown, the vehicle management system 100 includes a vehicle monitoring module 110 and a processing module 120. The vehicle monitoring module 110 is used to obtain vehicle monitoring data. The processing module 120 is electrically connected to the vehicle monitoring module 110, is used to analyze the vehicle monitoring data to obtain an analysis result, and perform an operation according to the analysis result. When there is a risk in the analysis result, a warning message is sent to the target terminal 130.

[0170] It can be understood that the information of the vehicle monitoring data collected by the vehicle monitoring module 110 mainly includes fault information and key data. The vehicle's overall vehicle controller, engine system, generator system, power battery system, drive motor system, transmission system, high-voltage auxiliary drive system, braking system, etc. send relevant information to the vehicle monitoring module 110 through the CAN bus. The vehicle monitoring module 110 can upload the collected vehicle monitoring data to the processing module 120 through a wireless network for immediate analysis or wait for information to be called. Among them, the fault information is analyzed according to the reported and uploaded mode, and the key information is analyzed according to the actual needs and uploaded in real time.

[0171] Through the above settings, the vehicle monitoring data is obtained through the vehicle monitoring module 110 and analyzed through the processing module 120, replacing the fixed setting of the overall vehicle fault threshold. It can be adjusted according to the vehicle type, etc., and the fault items that need to be warned can be increased or decreased in real time. It is analyzed according to different working conditions, different environments and other conditions, and the strategies for vehicle management are optimized and adjusted in a timely manner. At the same time, by sending a warning about the risks existing in the vehicle to the target terminal 130, it can play a warning role for one or more target terminals 130, which is beneficial to the information intercommunication between the target terminals 130.

[0172] The processing module 120 closely connects target terminals 130 such as vehicles, after-sales, and development to achieve information intercommunication, making the originally independent individuals no longer isolated. This can greatly enhance the user experience and confidence in using the vehicle, and also make after-sales service more timely and efficient. At the same time, the more powerful and flexible analysis system online breaks through the limitations of the single controller mode: it can further refine traditional fault requirements on the target terminal 130 and report them according to a multi-gradient mode, making the obtained information more detailed; at the same time, it can add more alarm monitoring requirements in addition to traditional faults; the setting of relevant monitoring thresholds is more flexible and can be modified at any time according to needs; combined with network-related information, more accurate and intelligent functions can be built, such as brake failure monitoring and warning, function strategy optimization, special user-specific data, etc.

[0173] In an alternative embodiment, the vehicle includes a methanol range extender. The vehicle monitoring data includes range extender monitoring data. The target terminal 130 includes a vehicle terminal 131 and a refueling point terminal 132 connected to the vehicle. The vehicle monitoring module 110 includes a range extender monitoring module 111, and the range extender monitoring module 111 is used to obtain range extender monitoring data. The range extender monitoring module 111 monitors the fault information and key data of the methanol range extender. The processing module 120 analyzes and statistically processes the information uploaded by the range extender monitoring module 111 through data analysis, and synchronously combines network information to make the data analysis more accurate. Among them, the fuel supply system can be evaluated for problems through data such as oil pressure signal, combustion characteristics, misfire, and knocking, the post-processor can be evaluated for failure or burnout through data such as front and rear oxygen sensors and temperature, and the zero position of the generator can be evaluated for normal status through the engine's rotational speed torque output combined with the generator's power output. Synchronously combine GPS positioning and network information, including factors such as weather, season, and market vehicle performance, so as to adjust the set threshold range and required functions in real time. The vehicle management system 100 further includes a vehicle receiving module and a refueling point receiving module. The vehicle receiving module is used to connect to the vehicle terminal 131, and the refueling point receiving module is used to connect to the refueling point terminal 132. The vehicle terminal 131 receives warning information from the processing module 120 through the vehicle receiving module. The refueling point terminal 132 receives warning information from the processing module 120 through the refueling point receiving module. The processing module 120 is electrically connected to the range extender monitoring module 111 and the refueling point receiving module, and is used to send a warning message to the vehicle terminal 131 and the refueling point terminal 132 when the analysis result is risky.

[0174] By setting a methanol range extender, the vehicle with a methanol fuel and pure electric system is organically combined. Utilizing the high energy density and long driving range advantages of methanol fuel, the problem of range anxiety of vehicles with a pure electric system is solved; on the other hand, the economic and environmental protection advantages of the pure electric system can be fully utilized to obtain the economy and road rights of pure electric vehicle models.

[0175] By acquiring the monitoring data of the range extender, the operating status and health of the methanol range extender are analyzed, and early warnings are given for possible risks of the methanol range extender. When there are risks in the methanol range extender, a warning is sent to the vehicle terminal 131 and the filling point terminal 132, which can play a warning role for the vehicle terminal 131 and the filling point terminal 132, and helps the filling point terminal 132 to timely learn about the methanol quality status, so that inspections and adjustments can be made in a timely manner, which is conducive to realizing information intercommunication between the vehicle terminal 131 and the filling point terminal 132.

[0176] In an optional embodiment, the range extender monitoring data includes a vehicle speed signal, a methanol liquid level signal, and a methanol quality signal. The range extender monitoring module 111 is used to acquire the vehicle speed signal and the methanol liquid level signal; and when the vehicle speed signal is 0 and the methanol liquid level signal increases, the methanol quality signal is acquired. The processing module 120 is used to send a methanol quality warning message to the vehicle receiving module and the filling point receiving module when the methanol quality signal is greater than or equal to the first methanol quality set value; and send a methanol quality safety message to the vehicle receiving module when the methanol quality signal is less than the first methanol quality set value.

[0177] When the vehicle speed signal is 0 and the methanol liquid level signal increases, the vehicle is being filled with methanol. At this time, the acquired methanol quality signal is affected by the methanol quality at the filling point. When the methanol quality signal is less than the first methanol quality set value, the methanol quality at the filling point is safe, and a methanol quality safety message is sent to the vehicle terminal 131, where the vehicle terminal 131 includes the vehicle terminal 131 being filled at this filling point and other vehicle terminals 131 waiting to be filled. Specifically, the filling points with safe methanol quality can be marked as green on the user's mobile phone. When the methanol quality signal is greater than or equal to the first methanol quality set value, there is a problem with the methanol quality at the filling point, and a methanol quality warning message is sent to the vehicle terminal 131 and the filling point terminal 132, where the vehicle terminal 131 includes the vehicle terminal 131 being filled at this filling point and other vehicle terminals 131 waiting to be filled. Specifically, the filling points with safe methanol quality can be marked as orange on the user's mobile phone, that is, to distinguish them from the filling points with safe methanol quality.

[0178] Through the above settings, by monitoring the methanol quality during vehicle filling through the range extender monitoring module 111, the methanol quality at the filling point is monitored in real time. When there is a problem with the methanol quality at the filling point, it can be timely discovered by the processing module 120 and informed to other users, so as to facilitate the monitoring of the methanol quality at the filling point, reduce the filling of methanol with problems by other vehicles, be conducive to the driving safety of vehicles equipped with methanol range extenders, control the methanol quality provided by the filling point, and improve the user experience.

[0180] Through the above settings, for different degrees of abnormalities in the methanol quality, the filling point and the vehicle terminal 131 are respectively prompted. When there is a problem with the methanol quality at the filling point, it can be detected in time and other users can be informed, so as to facilitate the monitoring of the methanol quality at the filling point and reduce the filling of methanol with problems by other vehicles, which is beneficial to the driving safety of vehicles equipped with methanol range extenders, controls the methanol quality provided by the filling point, and improves the user experience.

The processing module 120 is configured to send a methanol filling stop instruction to the filling point terminal 132 when the first count corresponding to the filling point reaches the set first set count.

[0182] Through the above settings, it is beneficial for the filling point to be able to detect in time the situation where the methanol quality is abnormal, so as to reduce the risk of methanol range extender failure caused by methanol with quality problems.

[0183] At the same time, it can reduce the frequency of checking the methanol quality at the filling point caused by minor abnormalities.

[0184] In an alternative embodiment, the processing module 120 includes a second counting module 122; the second counting module 122 is configured to perform a second count on the filling point when the inspection result of the filling point shows that the methanol quality signal is less than the first methanol quality set value. The processing module 120 is configured to send a methanol quality safety message to the vehicle terminal 131 when the second count corresponding to the filling point reaches the set second set count.

[0185] Through the above settings, the methanol quality safety of the filling point is determined through continuous multiple detection results, reducing the risk of detection errors, ensuring the safety of the methanol quality filled, being beneficial to the driving safety of vehicles equipped with methanol range extenders, controlling the methanol quality provided by the filling point, and improving the user experience.

The vehicle monitoring module 110 includes a motor monitoring module 112. The motor monitoring module 112 is configured to obtain the motor temperature signal. The processing module 120 is configured to trigger an over-temperature analysis of the motor when the motor temperature signal is greater than a set motor temperature, and issue a warning message to the vehicle terminal 131 and the repair point terminal 133 according to the motor over-temperature analysis. The vehicle management system 100 further includes a repair point receiving module, and the repair point receiving module is configured to connect to the repair point terminal 133. The repair point terminal 133 receives the warning message from the processing module 120 through the repair point receiving module.

[0187] The motor monitoring module 112 extracts, collects, and uploads the fault information and key data of the power battery, drive motor, auxiliary drive, etc. controllers to the processing module 120. The processing module 120 sets a more refined monitoring model according to factors such as GPS positioning, actual market vehicle conditions, project development progress, and environment, and monitors the health of each component of the three-electric system through the data analysis results. The processing module 120 performs an over-temperature analysis of the motor, issues a warning message to the vehicle terminal 131 and the repair point terminal 133, avoids the loss of power after the motor of the vehicle overheats, and can timely inform the repair point for maintenance, which is beneficial to the driving safety of the vehicle, reminds the repair point to prepare for maintenance or ensures that the repair point can provide maintenance services, thereby improving the user experience.

[0188] In an alternative embodiment, the vehicle monitoring module 110 is configured to obtain a vehicle identification code.

[0189] When the motor over-temperature analysis structure determines that the motor overheats due to reasons such as overloading, overweight, and long-time uphill driving of the vehicle, a warning message is sent to the vehicle terminal 131, suggesting that the user reduce the vehicle speed or gently step on the accelerator to relieve the motor over-temperature problem, avoid loss of power after the drive motor overheats, thereby reducing the risk of potential safety hazards and being beneficial to the driving safety of the vehicle. When the motor over-temperature analysis structure determines that there is no overloading or overweight problem with the vehicle, it indicates that the vehicle is in an abnormal working state. A warning message is sent to the vehicle terminal 131 and the maintenance point terminal 133. Specifically, it can trigger a service reminder at the maintenance point, inform the user that the vehicle is in an abnormal working state, and inform the user of the location of the nearest maintenance point, so as to achieve rapid vehicle repair, which is beneficial to the driving safety of the vehicle and improves the user experience.

[0190] In an alternative embodiment, the vehicle monitoring data includes at least one of a vehicle positioning signal, a load signal, a battery power signal, a battery current signal, a vehicle speed signal, a brake pedal opening degree signal, and a slope signal. The processing module 120 analyzes the vehicle monitoring data and obtains the highest predicted temperature at which the vehicle's brake operates; when the highest predicted temperature is greater than or equal to the first set highest temperature, a warning message is sent to the vehicle terminal 131.

[0191] By obtaining the highest predicted temperature of the vehicle, when the highest predicted temperature is greater than or equal to the first set highest temperature, the vehicle has a risk of stalling. Sending a warning message to the vehicle terminal 131 can give a warning to the user, thereby reducing risks such as vehicle stalling and brake failure, being beneficial to the driving safety of the vehicle, and improving the user experience.

[0192] In an alternative embodiment, the processing module 120 is configured to send a first-level warning message to the vehicle terminal 131 when the highest predicted temperature is greater than or equal to the first set highest temperature and less than the second set highest temperature.

The second-level warning message includes a sound warning message; when the highest predicted temperature is greater than or equal to the third set highest temperature, a third-level warning message is sent to the vehicle terminal 131.

[0193] When the highest pre-temperature is greater than or equal to the first set highest temperature and less than the second warning message, a first-level warning message is sent to the vehicle terminal 131. The first-level warning message includes a text warning message. For example, the user is reminded by text message that there is a risk of vehicle stall, and the message content includes information such as the recommended parking and cooling locations on this section of the road, driving suggestions to avoid brake failure, and the most likely location to cause a stall. When the highest pre-temperature is greater than or equal to the second set highest temperature and less than the third set highest temperature, a second-level warning message is sent to the vehicle terminal 131. The second-level warning message includes an audible warning message. For example, the user is reminded by text message that there is a risk of vehicle stall, and the message content includes information such as the recommended parking and cooling locations on this section of the road, driving suggestions to avoid brake failure, and the most likely location to cause a stall. At the same time, an intelligent voice reminder is sent by phone to inform the user of the stall risk. When the highest pre-temperature is greater than or equal to the third set highest temperature, a third-level warning message is sent to the vehicle terminal 131.

The vehicle management system 100 further includes a development terminal receiving module, and the development terminal receiving module is used to connect to the development terminal 134. The development terminal 134 receives the warning message from the processing module 120 through the development terminal receiving module.

For example, monitor and analyze the torque, rotational speed response time of the engine, and discharge current data of the power battery during the acceleration process. If it is found that the response rate of the engine has a large margin, while the discharge current of the power battery has approached the limit, in order to increase the service life of the power battery, the researchers at the development end can be reminded to optimize the response strategy to reduce the discharge rate of the battery. At the same time, dedicated analysis modules can also be established according to different user usage scenarios, such as urban transportation, highway logistics, mountainous areas, cold regions, etc., analyze specific vehicle parameters for different usage scenarios, and issue dedicated vehicle strategies for the vehicle according to the analysis results, so as to achieve the purpose of performance improvement.

[0197] Specifically, when the ratio of the battery current signal to the maximum allowable feedback current of the vehicle's battery is between 1.2 and 1.5 and the duration exceeds 0.5 seconds; or when the ratio of the battery current signal to the maximum allowable feedback current of the vehicle's battery exceeds 1.5 and the duration exceeds 0.2 seconds, a warning message is sent to the development end terminal 134, and the development end personnel evaluate whether the relevant strategies of the vehicle system are in an optimal state and optimize the suboptimal parts. If it is considered that there are indeed unreasonable parts in the vehicle strategy, the development end personnel optimize the unreasonable strategy, generate a software upgrade package after the optimization is completed, and release it to the vehicle terminal 131 through OTA. Thus, during the use of the vehicle, problems with the vehicle's overall strategy can be detected in a timely manner and optimized in a timely manner, which is beneficial to the driving safety of the vehicle and improves the user experience.
