Description

Technical Field

[0001] The present invention relates to the field of new energy technology, and in particular to a maintenance reminder method, device, automobile and computer-readable storage medium. Background Art

[0002] With the advancement of science and technology, the increasing scarcity of oil resources and the improvement of public environmental awareness, electric vehicles are gaining more and more attention. In recent years, electric vehicles have made significant progress. In order to solve the problem of short driving range of electric vehicles, various extended-range electric vehicles have emerged.

[0003] Extended-range electric vehicles have two driving modes: pure electric mode and extended-range mode. Some customers use the pure electric mode for a long time, and the range extender is not started for a long time (one month or even several months). If the oil is not changed, it may cause the engine oil to emulsify; some customers are accustomed to using the extended-range mode and use the range extender frequently every day; and for the above different situations, the traditional engine maintenance plan is obviously not universal. Summary of the Invention

[0004] The main purpose of the present invention is to provide a maintenance reminder method, device, automobile and computer-readable storage medium, aiming to solve the technical problem of how to configure a reasonable engine maintenance plan for extended-range electric vehicles to reduce users' usage costs and improve users' vehicle experience.

[0008] When it is monitored that the remaining maintenance mileage is not greater than a preset maintenance threshold, generating and pushing a maintenance reminder message;

[0009] When it is detected that the remaining maintenance mileage is zero, a maintenance identification bit is generated;

[0010] Generate maintenance warning information according to the maintenance identification position and push the maintenance warning information.

[0011] Optionally, before the step of generating maintenance warning information according to the maintenance identification bit and pushing the maintenance warning information, the step further includes:

[0012] Get the total mileage of the vehicle and the preset maximum mileage;

[0013] Calculating the difference between the preset maximum mileage and the total mileage of the vehicle to obtain a first difference;

[0014] When the first difference is less than zero, a maintenance identification bit is generated.

[0015] Optionally, the step of dynamically obtaining the remaining maintenance mileage includes:

[0016] Obtain the total accumulated power generation and average power consumption of the vehicle;

[0017] Dividing the total accumulated power generation by the average power consumption of the vehicle to obtain the extended range mileage;

[0018] The remaining maintenance mileage is dynamically obtained based on the extended-range driving mileage.

[0019] Optionally, after the step of generating maintenance warning information according to the maintenance identification bit and pushing the maintenance warning information, the following steps are included:

[0020] After the engine maintenance is completed, the extended range mileage and the total vehicle mileage are reset to zero.

[0021] Optionally, the step of dynamically obtaining the remaining maintenance mileage based on the extended-range driving mileage includes:

[0022] Get preset maintenance standard values;

[0023] Calculating the difference between the preset maintenance standard value and the extended-range mileage to obtain a second difference;

[0030] In addition, to achieve the above-mentioned purpose, the present invention further provides a maintenance reminder device, which includes:

[0031] An acquisition module, the acquisition module is used to dynamically acquire the remaining maintenance mileage;

[0032] a monitoring module, the monitoring module being used to dynamically monitor whether the remaining maintenance mileage is not greater than a preset maintenance threshold;

[0033] a prompt module, configured to generate and push a maintenance reminder message when monitoring that the remaining maintenance mileage is not greater than a preset maintenance threshold;

[0034] A generating module, configured to generate a maintenance identification bit when detecting that the remaining maintenance mileage is zero;

[0043] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0044] The main solution of the embodiment of the present invention is: a maintenance reminder method, which includes the following steps:

[0045] Dynamically obtain remaining maintenance mileage;

[0046] Dynamically monitoring whether the remaining maintenance mileage is not greater than a preset maintenance threshold;

[0047] When it is monitored that the remaining maintenance mileage is not greater than a preset maintenance threshold, generating and pushing a maintenance reminder message;

[0048] When it is detected that the remaining maintenance mileage is zero, a maintenance identification bit is generated;

[0049] Generate maintenance warning information according to the maintenance identification position and push the maintenance warning information.

[0050] Since extended-range electric vehicles have two driving modes, pure electric mode and extended-range mode, generally speaking, when the electric vehicle is fully charged, the range extender is rarely used in the working state. At this time, the vehicle's mileage has nothing to do with whether the engine is started. Therefore, the traditional method of judging the engine maintenance needs based solely on the vehicle's mileage is likely to cause the engine maintenance frequency to be too high, increasing the user's vehicle use cost. At the same time, the range extender being in a non-working state for a long time is also likely to cause problems such as gumming of the engine oil circuit and carbon deposits in the air circuit of the range extender, which can easily damage the range extender. Some customers are accustomed to using the extended-range mode and use the range extender very frequently every day. If the traditional engine maintenance plan is followed, the maintenance frequency will be too low, which can also easily damage the engine.

[0051] This embodiment provides a maintenance reminder method that overcomes the technical problem in the prior art that the general engine maintenance strategy is not applicable to extended-range electric vehicles with inconsistent engine usage frequencies. In the maintenance reminder method, the remaining maintenance mileage is dynamically obtained; the remaining maintenance mileage is dynamically monitored to see if it is not greater than a preset maintenance threshold; when it is monitored that the remaining maintenance mileage is not greater than the preset maintenance threshold, a maintenance reminder message is generated and pushed, so that both the user and the customer service platform receive a reminder message that the engine is about to reach the maintenance mileage; a maintenance flag is generated based on the maintenance reminder message; when it is monitored that the remaining maintenance mileage is equal to zero, a maintenance flag is generated; a maintenance warning message is generated based on the maintenance flag and pushed, so that both the user and the customer service platform receive a warning message that the engine urgently needs maintenance, urging the user to maintain the engine in a timely manner. This embodiment effectively solves the problem of users not knowing how to maintain the engine of an extended-range vehicle, reduces the probability of the engine being damaged due to improper maintenance, reduces the additional maintenance costs incurred by users due to improper maintenance, and improves the user's car experience.

[0085] The step of obtaining the cumulative power generation of the current driving cycle includes:

[0086] The real-time power generated by the generator is obtained, and the real-time power generated at each moment is accumulated to obtain the cumulative power generation of the current driving cycle.

[0087] The embodiment of the present invention provides a maintenance reminder method, referring to Figure 2, Figure 2 The figure is a flow chart of an embodiment of a maintenance reminder method of the present invention.

[0088] In this embodiment, the maintenance reminder method includes:

[0089] Step S10, dynamically obtaining the remaining maintenance mileage;

[0090] It should be noted that, in this embodiment, the executing entity is the automobile in the above embodiment. Specifically, the technical solution provided in this embodiment can be executed by the vehicle controller or instrument controller in the automobile; the remaining maintenance mileage refers to the remaining maintenance mileage of the engine or range extender. The remaining maintenance mileage serves as the maintenance basis for the engine or range extender, and is used to help users determine the best maintenance time for the engine or range extender.

[0091] It is understandable that if the car is in motion, the remaining maintenance mileage may change in real time. If the car is running in extended-range mode, the remaining maintenance mileage will gradually decrease with running time. If the car is running in pure electric mode, the remaining maintenance mileage will remain unchanged.

[0092] As an example, in this embodiment, step S10 includes:

[0093] Step S11, obtaining the total accumulated power generation and the average power consumption of the vehicle;

[0094] Step S12, dividing the total accumulated power generation by the average power consumption of the vehicle to obtain the extended-range driving mileage;

[0095] Step S13: dynamically obtaining the remaining maintenance mileage based on the extended-range driving mileage.

[0096] As an example, in this embodiment, the step of obtaining the total accumulated power generation in step S11 includes:

[0097] Step S111, obtaining the cumulative power generation of the current driving cycle and the cumulative power generation of the previous driving cycle; wherein the step of obtaining the cumulative power generation of the current driving cycle includes: obtaining real-time power generation feedback from the generator, and accumulating the real-time power generation at each moment to obtain the cumulative power generation of the current driving cycle;

[0098] Step S112 : Adding the accumulated power generation of the current driving cycle and the accumulated power generation of the previous driving cycle to obtain a total accumulated power generation.

[0099] As an example, in this embodiment, step S13 includes:

[0100] Step S131, obtaining a preset maintenance standard value;

[0101] Step S132, calculating the difference between the preset maintenance standard value and the extended-range mileage to obtain a second difference;

[0102] Step S133: taking the second difference as the remaining maintenance mileage.

[0103] It should be noted that in this embodiment, during vehicle operation, the range extender control module reads the real-time power generated by the generator and accumulates it to obtain the cumulative power generation for the current driving cycle. This is then added to the cumulative power generation for the previous driving cycle read from the controller storage module to obtain the total cumulative power generation. The calculated total cumulative power generation is then divided by the average power consumption of the entire vehicle (i.e., the average vehicle power consumption) to obtain the extended-range operating mileage. The preset maintenance standard value is the maximum mileage that the vehicle can travel in extended-range mode alone, i.e., relying solely on the engine or range extender as a power source. This value can be set by the vehicle service provider or after-sales personnel. The calculated extended-range operating mileage is subtracted from the preset maintenance standard value. The resulting second difference represents the remaining engine mileage, also known as the engine's remaining maintenance mileage. Specifically, after driving the distance corresponding to the engine's remaining maintenance mileage in extended-range mode, the engine must be serviced to better minimize engine wear.

[0104] Step S20, dynamically monitoring whether the remaining maintenance mileage is not greater than a preset maintenance threshold;

[0105] It should be noted that the preset maintenance threshold can be set by the automobile service provider or after-sales personnel. This value serves as a critical reference value for comparison with the remaining maintenance mileage to determine whether the mileage the engine has run is excessive. Obviously, the preset maintenance threshold is smaller than the preset maintenance standard value. For example, if the preset maintenance standard value is set to 10,000 kilometers or 5,000 kilometers, the preset maintenance threshold can be set to 500 kilometers or 300 kilometers, and so on. This embodiment does not impose any restrictions on this.

[0106] It will be appreciated that once the engine's remaining maintenance mileage value is obtained, it is immediately compared with a preset maintenance threshold to determine whether the engine's remaining maintenance mileage value is less than or equal to the preset maintenance threshold, thereby determining whether the engine is nearing the critical point requiring maintenance. Whenever the remaining maintenance mileage value is updated, the comparison result between the remaining maintenance mileage value and the preset maintenance threshold is also updated.

[0107] Step S30, when it is monitored that the remaining maintenance mileage is not greater than a preset maintenance threshold, generating and pushing a maintenance reminder message;

[0108] It should be noted that the pending maintenance reminder information is generated when the remaining maintenance mileage is detected to be no greater than a preset maintenance threshold, and is used to alert the user that the engine is about to reach a state requiring maintenance. In this embodiment, the accumulated power generation, remaining engine maintenance mileage, and engine maintenance reminder information are transmitted to the vehicle's local area network (LAN) via signals. Upon receiving the relevant signals, a gateway within the LAN forwards them to an instrument cluster (IC) and a telematics box (TBOX, a vehicle network system that uses long-distance communication and information technology to provide vehicle data collection, remote query and control, fault monitoring, and other services). Upon receiving the engine maintenance reminder information, the instrument cluster notifies the user via voice messages, such as spitting, wheezing, or coughing sounds, to inform the user that the engine is about to reach a critical maintenance point. Upon receiving the engine maintenance reminder information, the TBOX system uploads it to the after-sales platform, which pushes the information to regional account managers. The frequency of push notifications can be customized (e.g., once a day for three days), and the account managers proactively remind the customer that the engine is due for maintenance.

[0109] Step S40, when it is detected that the remaining maintenance mileage is zero, generating a maintenance identification bit;

[0110] It should be noted that the maintenance identification bit represents an indication that the engine urgently needs maintenance. When it is monitored that the remaining maintenance mileage is equal to zero, the maintenance identification bit will be automatically generated. This generation method is based on monitoring the remaining maintenance mileage of the range extender or engine.

[0111] As an example, this embodiment further includes:

[0112] Step S41, obtaining the total mileage of the vehicle and the preset maximum mileage; calculating the difference between the preset maximum mileage and the total mileage of the vehicle to obtain a first difference; when the first difference is less than zero, generating a maintenance identification bit.

[0113] It should be noted that in this embodiment, the maintenance indicator is also generated in another manner, namely, based on the difference between the vehicle's total mileage and a preset maximum mileage. The total mileage refers to the combined mileage of the vehicle in extended-range mode and pure electric mode. The preset maximum mileage can be set by the vehicle service provider or after-sales personnel, indicating that after the vehicle's mileage reaches the maximum mileage, a scheduled maintenance must be performed to ensure the user's driving safety. If the first difference is less than zero, it clearly indicates that the vehicle's total mileage has exceeded the preset maximum mileage. For example, if the preset maximum mileage is 30,000 kilometers and the vehicle's total mileage has reached 30,024 kilometers, then the second difference is -24 kilometers, indicating that the vehicle has exceeded the time for maintenance and servicing. Continued use of the vehicle at this point would pose a significant risk and could affect the user's personal safety. Therefore, the vehicle should be serviced and maintained immediately.

[0114] Step S50: Generate maintenance warning information according to the maintenance identification bit and push the maintenance warning information.

[0115] It should be noted that when the maintenance identification bit is generated, unlike the engine maintenance reminder information, a maintenance warning information will be automatically generated at this time to attract the user's attention in a stronger form. In this embodiment, the cumulative power generation, remaining mileage of engine maintenance, engine maintenance reminder information, maintenance identification bit and total mileage of the vehicle will all be sent to the car local area network in the form of signals; the gateway in the car local area network will forward the relevant signal to the instrument and the car networking system after receiving it; after the instrument receives the maintenance identification bit, it will light up the maintenance reminder light and play a voice prompt to remind the user that the engine needs to be maintained immediately; and after receiving the maintenance identification bit, the car networking system will upload it to the after-sales platform, and the after-sales platform will push the information to the regional account manager. The frequency of pushing information can be set by yourself (for example, three times a day for five days), and the account manager will actively warn the customer that for the safety of your car, the engine must be maintained.

[0116] As an example, in this embodiment, the following steps after step S50 include: when the engine maintenance is completed, clearing the extended-range mileage and the total vehicle mileage.

[0117] It should be noted that after the customer performs maintenance, the engine has been maintained. At this time, data such as the extended-range mileage and total vehicle mileage used to determine whether the engine needs maintenance can be reset to zero, and then restarted as the user uses the vehicle, so as to accurately know the next time the range extender or engine needs maintenance.

[0118] In this embodiment, a maintenance reminder method is provided, which overcomes the technical problem that the general engine maintenance strategy in the prior art is not applicable to extended-range electric vehicles with inconsistent engine usage frequencies. In the maintenance reminder method, the remaining maintenance mileage is dynamically obtained; the remaining maintenance mileage is dynamically monitored to see if it is not greater than a preset maintenance threshold; when it is monitored that the remaining maintenance mileage is not greater than the preset maintenance threshold, a maintenance reminder message is generated and pushed, so that both the user and the customer service platform can receive a reminder message that the engine is about to reach the maintenance mileage; a maintenance identification bit is generated based on the maintenance reminder message; when it is monitored that the remaining maintenance mileage is equal to zero, a maintenance identification bit is generated; a maintenance warning message is generated based on the maintenance identification bit and pushed, so that both the user and the customer service platform can receive a warning message that the engine urgently needs maintenance, urging the user to maintain the engine in a timely manner. This embodiment effectively solves the problem that users do not know how to maintain the engine of an extended-range vehicle, reduces the probability of the engine being damaged due to improper maintenance, reduces the additional maintenance costs incurred by users due to improper maintenance, and improves the user's car experience.

[0119] In addition, the embodiment of the present invention also provides a maintenance reminder device, referring to Figure 3 , Figure 3 Schematic diagram of the functional modules of an embodiment of the maintenance reminder device of the present invention.
