Description

Technical Field

[0001] This application relates to vehicle engineering technology, and more particularly to a method, apparatus, electronic device, and storage medium for maintaining components of a range-extended vehicle. Background Technology

[0002] Automotive equipment maintenance is typically based directly on mileage. However, for range-extended electric vehicles (REEVs), which are powered by a battery that is charged by an external charging station or generated by the range extender, the range extender is not continuously running during operation. Therefore, it's impossible to determine the maintenance needs of the range extender engine based on the vehicle's actual mileage. In other words, mileage-based maintenance methods cannot meet the maintenance needs of REEVs, and the data used for equipment maintenance is not reliable.

[0003] There is a need for a component maintenance method for range-extended electric vehicles to improve the effectiveness of the computational data used in component maintenance in range-extended electric vehicles. Summary of the Invention

[0066] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0067] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0068] The automotive industry is gradually moving towards new energy sources, but the driving range of pure electric vehicles has been severely limited by battery energy density. At the same time, the number of charging stations and grid load also restrict the rapid development of pure electric vehicles, leading to the emergence of range extender systems. The electricity generated by the range extender can both charge the battery and be directly output to the drive motor to participate in driving, thereby increasing the driving range and reducing dependence on charging stations to some extent.

[0069] The range extender consists of an engine, an engine controller, a generator, a generator controller, and a range extender controller. Due to the engine's characteristics, regular maintenance is required to ensure engine reliability.

[0070] Traditional car engines are directly linked to vehicle mileage, using mileage as the standard for determining engine maintenance for range extenders. However, in range-extended vehicles, the range extender does not directly drive the vehicle, so the vehicle mileage cannot accurately reflect the range extender's usage and cannot be directly used as a basis for engine maintenance. Therefore, a new maintenance plan needs to be designed.

[0071] In summary, the following issues exist in the maintenance of components in range-extended electric vehicles:

[0072] Range-extended electric vehicles are powered by a power battery. The power battery's energy comes from external charging stations or the range extender's power generation. When a range-extended vehicle is running, the range extender is not in a continuous running state, so the range extender's engine maintenance needs cannot be determined based on the vehicle's actual mileage.

[0073] The operating speed of a range-extended vehicle is decoupled from the speed and power of the range extender. Therefore, the operating time of the range-extended vehicle cannot accurately reflect the operating time of the range extender and cannot be used as a basis for range extender maintenance.

[0074] However, traditional automotive component maintenance, such as engine maintenance, is based on mileage and does not reflect the vehicle's actual load. Different cars have different operating loads, but the maintenance interval mileage is the same. Within each maintenance cycle, the engine's wear and tear varies across different cars, ultimately affecting the engine's actual lifespan. This patent's maintenance strategy is linked to the range extender engine load, more accurately reflecting maintenance needs.

[0075] Traditional car engine spark plugs, belts and other wear parts are maintained according to the car's maintenance mileage. However, different cars have different usage environments and operating conditions. Sometimes the maintenance mileage has been reached but the parts are still in good condition and can continue to be used. Therefore, maintaining according to the mileage can be wasteful.

[0076] Therefore, traditional methods for determining the maintenance status of automobiles are not applicable to range-extended electric vehicles (REEVs), and it is necessary to develop maintenance determination methods suitable for REEVs.

[0077] The method provided in this application uses the power generation of the range extender as the basis for maintenance, thus overcoming the problem that the operating mileage of range-extended vehicles cannot accurately reflect the engine's operating mileage and condition, and ensuring that the operating characteristics are basically the same for each maintenance cycle.

[0078] This application allows for setting thresholds based on different cumulative power generation for different maintenance items of the range extender engine, reminding vehicle owners to perform maintenance.

[0079] Example 1

[0080] Please see Figure 1 , Figure 1 This is a schematic diagram of a maintenance method for range-extended vehicle components disclosed in an embodiment of the present invention. Figure 1 As shown, the method includes:

[0081] S101. Determine the target component to be maintained, and the target threshold for component maintenance for each target component;

[0082] The target components may include the various components of a range-extended vehicle. A typical maintenance target is the range-extender engine of the range-extender vehicle. As mentioned above, the range extender in a range-extender vehicle includes an engine, engine controller, generator, generator controller, and range extender controller. The methods provided in this application can also be applied to maintain these specific components.

[0083] It should be noted that Example 2 only lists specific maintenance schemes for range-extended engines and does not mean that this application can only be applied to range-extended engines; the specific application depends on the actual application scenario. Furthermore, specific components of the engine, such as spark plugs, belts, and other easily worn parts, can also have corresponding target thresholds designed to determine whether the corresponding components meet the maintenance requirements based on the range extender's operating parameters.

[0084] S102. Obtain the operating parameters of the range extender;

[0085] The main operating parameters of the range extender include power generation and the corresponding power generation time at each power level, aiming to obtain the power generation at each time period and the total power generation during the range extender's operating life. To enhance the value of the data and enable subsequent analysis, the collected data can be cleaned and processed to generate corresponding dynamic curves or other forms of charts.

[0086] It should be noted that S102 and S101 are two independent steps with no explicit order, but logically both should precede step S103. The diagram only shows one possible implementation. In actual process design, S102 can be performed before or simultaneously with S101.

[0087] S103. Determine whether the operating parameters of the range extender meet the maintenance conditions indicated by the target threshold.

[0088] S104. If it is determined that the operating parameters of the range extender meet the maintenance conditions indicated by the target threshold, then a preset maintenance operation is performed on the corresponding target component.

[0089] In the process of establishing the target threshold, it is necessary to associate the target threshold with the load. The determined target threshold is compared with the range extender operating parameters that are also related to the load. This allows the maintenance conditions to be directly associated with the load, reducing the problem of poor data performance in traditional methods for determining maintenance conditions. In other words, the range extender does not directly drive the vehicle, and the vehicle's mileage cannot truly reflect the usage of the range extender, so it cannot be directly used as the basis for judging the maintenance of the range extender engine.

[0090] The range-extended vehicle component maintenance method provided in this embodiment identifies the target component in the range-extended vehicle and obtains the corresponding target threshold. The range extender operating parameters are converted into reference quantities with the same dimensions as the target threshold. This determines whether the range extender operating parameters meet the maintenance conditions indicated by the target threshold. When the conditions are met, a signal is issued or a preset maintenance operation is automatically executed. This improves the automation level of range-extended vehicle component maintenance and enhances the accuracy and efficiency of maintenance by improving the effectiveness of the calculation data used in component maintenance in range-extended vehicles.

[0091] Example 2

[0092] Please see Figure 2 , Figure 2 This is a schematic diagram of another maintenance method for range-extended vehicle components disclosed in an embodiment of the present invention. Figure 2 As shown, the target component includes a range-extended engine, and the method includes:

[0093] S201. Obtain historical maintenance mileage data for gasoline engines and / or other range-extended engines as equivalent maintenance mileage.

[0094] S202. The equivalent maintenance mileage is determined as the target threshold corresponding to the range-extended engine;

[0095] Historical data can be obtained through publicly available databases or self-made databases in the field. Based on historical maintenance mileage data of fuel engines and / or other range-extended engines, the corresponding equivalent maintenance mileage can be determined as the target threshold.

[0096] S203. Obtain the operating parameters of the range extender;

[0097] S204. Determine whether the operating parameters of the range extender meet the maintenance conditions indicated by the target threshold.

[0098] S205. If it is determined that the operating parameters of the range extender meet the maintenance conditions indicated by the target threshold, then a preset maintenance operation is performed on the corresponding target component.

[0099] It should be noted that the relevant descriptions of S203-S205 can be found in the relevant descriptions of S102-S104 in Embodiment 1, and will not be repeated here.

[0100] As an optional implementation, the range extender operating parameters include cycle power generation and total power generation, and obtaining the range extender operating parameters includes:

[0101] Obtain the range extender's power output and the corresponding power output time;

[0102] Based on the power generation capacity and the corresponding power generation time, determine the periodic power generation within the equivalent maintenance mileage and the total power generation corresponding to the total working time of the range extender generator.

[0103] As mentioned earlier, a corresponding load chart can be generated based on the range extender's power output and the corresponding power generation time, making the acquired data more analyzable. The determination of the cycle power generation within the equivalent maintenance mileage and the total power generation corresponding to the total operating time of the range extender generator, based on the power output and corresponding power generation time, can be performed through accurate integration calculations using actual data, or by multiplying the data in segments after preprocessing, depending on the specific data accuracy requirements. The cycle power generation and total power generation can be used individually or simultaneously as the criteria for determining whether maintenance is required.

[0104] By obtaining the power output of the range extender and the corresponding power generation time, the periodic power output and total power output can be determined, which can then be used to calculate the equivalent operating mileage. By comparing this with the equivalent maintenance mileage, it can be determined whether the current target component needs maintenance, thereby improving the accuracy and efficiency of maintenance.

[0105] As an optional implementation, after determining the periodic power generation corresponding to the equivalent maintenance mileage and the total power generation corresponding to the total operating time of the range-extended generator based on the power generation capacity and the corresponding power generation time, the method further includes:

[0106] Determine the power consumption per 100 kilometers of the range-extended generator;

[0107] Based on the periodic power generation and the power consumption per 100 kilometers, the equivalent periodic operating mileage of the range-extended generator is determined.

[0108] The power consumption per 100 kilometers can be used to calculate the corresponding operating mileage. The equivalent operating mileage can be obtained by dividing the periodic power generation by the power consumption per 100 kilometers and then multiplying by 100 kilometers.

[0109] It should be noted that the power consumption per 100 kilometers mentioned here is only an example; obtaining other units of power consumption will achieve the same effect. If the mileage unit is not multiplied, an equivalent ratio is obtained. Based on this equivalent ratio, the converted equivalent mileage, or the original power consumption data, it is possible to determine whether the target component meets the maintenance conditions. However, the two data units used for comparison should be consistent. For example, power consumption is compared with power consumption, and mileage is compared with mileage. Please refer to the steps below for details.

[0110] The step of determining whether the operating parameters of the range extender meet the maintenance conditions indicated by the target threshold includes:

[0111] Determine whether the equivalent cycle operating mileage is greater than or equal to the equivalent maintenance mileage;

[0112] Wherein, if it is determined that the operating parameters of the range extender meet the maintenance conditions indicated by the target threshold, then a preset maintenance operation is performed on the corresponding target component, including:

[0113] If it is determined that the equivalent cycle operating mileage is greater than or equal to the equivalent maintenance mileage, a maintenance instruction signal is issued, and a preset maintenance operation is performed on the range-extended generator.

[0114] If it is determined that the equivalent cycle operating mileage is greater than or equal to the equivalent maintenance mileage, a maintenance instruction signal is issued and a preset maintenance operation is performed on the range-extended generator. This should be understood as either issuing a maintenance instruction signal to issue an alarm or transmitting it to a preset terminal to notify technicians to handle it, or directly and automatically handling the corresponding components according to the preset maintenance process, or both.

[0115] By determining the power consumption per 100 kilometers, the determined power generation can be converted into actual operating mileage. This establishes a link between operating mileage and load conditions, improving the effectiveness of equivalent operating mileage calculation in the range-extended vehicle environment, and thus improving the accuracy and efficiency of maintenance.

[0116] As an optional implementation, after determining the power consumption per 100 kilometers of the range-extended generator, the method further includes:

[0117] Based on the total power generation and the power consumption per 100 kilometers, the equivalent total operating mileage of the range-extended generator is determined;

[0118] Based on the equivalent maintenance mileage, the equivalent total maintenance mileage of the range-extended engine is determined;

[0119] Furthermore, the step of determining whether the operating parameters of the range extender meet the maintenance conditions indicated by the target threshold also includes:

[0120] Determine whether the equivalent total operating mileage is greater than or equal to the equivalent total maintenance mileage;

[0121] Furthermore, the step of performing a preset maintenance operation on the corresponding target component if it is determined that the operating parameters of the range extender meet the maintenance conditions indicated by the target threshold also includes:

[0122] If it is determined that the equivalent total operating mileage is greater than or equal to the equivalent total maintenance mileage, a maintenance instruction signal is issued, and a preset maintenance operation is performed on the range-extended generator.

[0123] The conditions corresponding to the total maintenance mileage and the conditions corresponding to the periodic maintenance mileage can be used as two parallel and independent maintenance criteria. Maintenance operations are performed when either one is met, or when both are met, depending on the actual application scenario.

[0124] By determining the power consumption per 100 kilometers, the determined power generation can be converted into the actual total operating mileage. This establishes a link between the total operating mileage and the load condition. When the total operating mileage or the periodic operating mileage reaches the maintenance conditions, maintenance operations are performed. This improves the effectiveness of equivalent operating mileage calculation in the range-extended vehicle environment, thereby improving the accuracy and efficiency of maintenance.

[0125] Please see Figure 3 , Figure 3 This is a schematic diagram illustrating an application scenario of a maintenance method for range-extended vehicle components disclosed in an embodiment of the present invention. For example... Figure 3 As shown, in a practical scenario, the method can be implemented as follows:

[0126] The range extender controller collects the range extender's power output and power generation time at each power level, and calculates the cumulative power output and total power output of the range extender.

[0127] Since the engine oil used in the range extender engine is the same as that used in traditional gasoline vehicles, historical maintenance mileage data of gasoline engines is obtained. The maintenance mileage limit of traditional gasoline vehicles is used as the equivalent maintenance mileage of range extender vehicles. The equivalent power generation of range extender vehicles within one maintenance cycle is calculated in this way, and this is used as the threshold for maintenance of range extender engine.

[0128] During operation, the system continuously calculates and periodically judges whether the cumulative or total power generation of the range extender reaches the equivalent power generation threshold of the oil maintenance cycle, or whether the mileage converted from the power generation data reaches the corresponding mileage threshold. In these cases, the range extender controller sends a range extender maintenance signal to remind the owner to perform engine maintenance.

[0129] Different components are designed with different power generation reminder maintenance thresholds. For example, the maintenance cycle of easily worn parts such as spark plugs and belts can also be calculated based on the equivalent driving mileage calculated from their respective cumulative power generation.

[0130] After each maintenance, the range extender's power generation is recalculated, and the total power generation is added up.

[0131] The range-extended vehicle component maintenance method provided in this embodiment determines the equivalent maintenance mileage by acquiring historical data, uses the equivalent maintenance mileage as a target threshold, improves the effectiveness of the data, and can establish a relationship between the target threshold and vehicle load, thereby improving the accuracy and efficiency of maintenance.

[0132] Example 3

[0133] This invention also provides a range-extended vehicle component maintenance device to implement the aforementioned method; please refer to [link to relevant documentation]. Figure 4 , Figure 4 This is a schematic diagram of the structure of a range-extended vehicle component maintenance device disclosed in an embodiment of the present invention. Figure 4 As shown, based on any other embodiment, the apparatus includes:

[0134] The threshold determination module 31 is used to determine the target component to be maintained, and the target threshold for component maintenance for each target component;

[0135] Parameter acquisition module 32 is used to acquire the operating parameters of the range extender;

[0136] The judgment module 33 is used to determine whether the operating parameters of the range extender meet the maintenance conditions indicated by the target threshold.

[0137] The maintenance module 34 is used to perform preset maintenance operations on the corresponding target components if it is determined that the operating parameters of the range extender meet the maintenance conditions indicated by the target threshold.

[0138] By identifying target components in range-extended electric vehicles and obtaining corresponding target thresholds, the operating parameters of the range extender are converted into reference quantities with dimensions consistent with the target thresholds. This allows for the determination of whether the operating parameters of the range extender meet the maintenance conditions indicated by the target thresholds. If the conditions are met, a signal is issued or preset maintenance operations are automatically executed. This improves the automation level of range-extended electric vehicle component maintenance and enhances the accuracy and efficiency of maintenance by improving the effectiveness of the computational data used in component maintenance in range-extended electric vehicles.

[0141] The equivalent maintenance mileage is determined as the target threshold corresponding to the range-extended engine.

[0142] By obtaining historical data to determine the equivalent maintenance mileage, and using the equivalent maintenance mileage as a target threshold, the effectiveness of the data is improved. Furthermore, the target threshold can be linked to vehicle load, thereby improving the accuracy and efficiency of maintenance.

[0143] As an optional implementation, the range extender operating parameters include cycle power generation and total power generation. The specific method by which the parameter acquisition module acquires the range extender operating parameters includes:

[0145] Based on the power generation capacity and the corresponding power generation time, determine the periodic power generation within the equivalent maintenance mileage and the total power generation corresponding to the total working time of the range extender generator.

[0146] By obtaining the power output of the range extender and the corresponding power generation time, the periodic power output and total power output can be determined, which can then be used to calculate the equivalent operating mileage. By comparing this with the equivalent maintenance mileage, it can be determined whether the current target component needs maintenance, thereby improving the accuracy and efficiency of maintenance.

[0147] As an optional implementation method, Figure 5 This is a schematic diagram of another range-extended vehicle component maintenance device disclosed in an embodiment of the present invention. Figure 5 As shown, the device also includes a mileage calculation module 35, which is used to determine the power consumption per 100 kilometers of the range extender generator after the parameter acquisition module 32 determines the periodic power generation corresponding to the equivalent maintenance mileage and the total power generation corresponding to the total working time of the range extender generator based on the power generation and the corresponding power generation time.

[0148] Based on the periodic power generation and the power consumption per 100 kilometers, the equivalent periodic operating mileage of the range-extended generator is determined.

[0149] The specific method by which the judgment module 33 judges whether the operating parameters of the range extender meet the maintenance conditions indicated by the target threshold includes:

[0150] Determine whether the equivalent cycle operating mileage is greater than or equal to the equivalent maintenance mileage;

[0151] Wherein, if the maintenance module 34 determines that the operating parameters of the range extender meet the maintenance conditions indicated by the target threshold, the specific method for performing a preset maintenance operation on the corresponding target component includes:

[0152] If it is determined that the equivalent cycle operating mileage is greater than or equal to the equivalent maintenance mileage, a maintenance instruction signal is issued, and a preset maintenance operation is performed on the range-extended generator.

[0153] By determining the power consumption per 100 kilometers, the determined power generation can be converted into actual operating mileage. This establishes a link between operating mileage and load conditions, improving the effectiveness of equivalent operating mileage calculation in the range-extended vehicle environment, and thus improving the accuracy and efficiency of maintenance.

[0154] As an optional implementation, the mileage calculation module 35 is further configured to determine the equivalent total operating mileage of the range-extended generator based on the total power generation and the power consumption per 100 kilometers after determining the power consumption per 100 kilometers of the range-extended generator.

[0157] Determine whether the equivalent total operating mileage is greater than or equal to the equivalent total maintenance mileage;

[0158] Furthermore, if the maintenance module 34 determines that the operating parameters of the range extender meet the maintenance conditions indicated by the target threshold, the specific method for performing a preset maintenance operation on the corresponding target component further includes:

[0159] If it is determined that the equivalent total operating mileage is greater than or equal to the equivalent total maintenance mileage, a maintenance instruction signal is issued, and a preset maintenance operation is performed on the range-extended generator.

[0160] By determining the power consumption per 100 kilometers, the determined power generation can be converted into the actual total operating mileage. This establishes a link between the total operating mileage and the load condition. When the total operating mileage or the periodic operating mileage reaches the maintenance conditions, maintenance operations are performed. This improves the effectiveness of equivalent operating mileage calculation in the range-extended vehicle environment, thereby improving the accuracy and efficiency of maintenance.
