Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobiles, and particularly to a small break mode control method applied to a range extended automobile and related equipment. BACKGROUND

[0002] The range extended automobile is provided with components such as a power battery, a driving motor and a range extender. When the power battery has sufficient power storage, the driving motor can be completely discharged by the power battery to provide power, thereby realizing the function of a pure electric vehicle. The range extender can generate power by burning fuel to charge the power battery, thereby playing a role of range extension. The power battery can also be externally connected to a commercial power supply for charging. Therefore, the range extended automobile has the advantages of a pure electric vehicle, such as low use cost, large horsepower and high energy conversion efficiency, and the advantages of a pure fuel vehicle, such as strong endurance and fast energy supplement. Moreover, if the user can ensure that the power battery is charged at a charging pile within the endurance range corresponding to the capacity of the power battery, the range extender can be used for power generation for a long time, and the range extended automobile can be used as a pure electric vehicle, thereby fully exerting the advantages of low use cost, large horsepower and high energy conversion efficiency.

[0003] Due to the characteristics of commercial power supply, such as large-scale supply, and the characteristics of an internal combustion engine, such as low energy conversion efficiency, the cost of charging the power battery by using commercial power supply is generally lower than the cost of charging the power battery by using the range extender in the range extended automobile. Therefore, the user usually needs to plan the use of the range extended automobile, and try to drive the range extended automobile to a charging pile within the endurance range of the range extended automobile to charge the power battery by using commercial power supply, so as to reduce the use of the range extender and thereby reduce the use cost of the range extended automobile.

[0004] The vehicle-mounted electrical appliances provided on the extended-range vehicle include a driving motor, an air conditioner, an audio and video entertainment system, and the like. In the traditional use of the vehicle, the user only uses the vehicle-mounted electrical appliances such as the air conditioner and the audio and video entertainment system when driving the vehicle (equivalent to when the driving motor is working), that is, the vehicle-mounted electrical appliances are only used when the vehicle is running, so the planning of the use of the extended-range vehicle is actually equivalent to the planning of the running of the extended-range vehicle, and the user only needs to plan the running route, for example, to set the running route to pass through a charging station and the like. However, with the deepening of the intelligentization of the vehicle, the use of the vehicle is more and more integrated into people's life, and the user more and more uses the functions of the vehicle other than running. For example, the nap mode is a typical representative of the functions of the vehicle other than running. When the extended-range vehicle is used in the nap mode, it also needs to be powered by the power battery as when driving the extended-range vehicle, so if it is necessary to reduce the use cost of the extended-range vehicle, it is also necessary to reasonably set the use of the nap mode, so as to plan the nap mode. However, the setting of the nap mode needs to configure many parameters, which causes inconvenience to the user, and non-professional users may face some difficulties, so they cannot optimize the setting of the nap mode, and therefore the comprehensive influence of the user experience provided by the nap mode, the use cost of the extended-range vehicle caused by the nap mode and the like is not good.

Figure 4 This is a timeline diagram of each step in the rest mode control method applied to range-extended electric vehicles in the embodiment. Detailed Implementation

[0018] In this embodiment, the range-extended vehicle that can apply the nap mode control method has Figure 1 The structure shown. (Refer to...) Figure 1Range-extended electric vehicles are equipped with a control module, battery components, range extender, biometric sensors, environmental parameter sensors, communication module, and multiple on-board functional components. The control module is a component with functions such as data acquisition, data processing, data output, and control. For example, an Electronic Control Unit (ECU) can be used as the control module. The battery component includes battery cells (e.g., lithium-ion cells) and a battery management system (BMS) that manages the cells. The cells supply power to the drive motor and on-board components and receive charging from the range extender or an external charging station. Under the control of the control module, the BMS controls and manages the charging and discharging process of the cells and monitors parameters such as the cell's operating temperature, charging and discharging voltage, charging and discharging current, and remaining charge in real time, sending these parameters to the control module. The range extender has a fuel tank, an internal combustion engine, a generator, and technical indicator sensors. The fuel tank stores gasoline and other fuels. When the range extender is working, the fuel tank supplies fuel to the internal combustion engine, which converts the heat energy generated by burning the fuel into mechanical energy to drive the generator. The generator sends the output current to the BMS, which charges the battery cells. The technical indicator sensors can be installed in the fuel tank to detect the fuel level and obtain data. Technical indicators such as content and viscosity are detected and sent to the control module. Biometric sensors, specifically cameras installed inside the vehicle, capture images and process them to detect the presence of human biometrics. These biometrics are then sent to the control module, indicating whether someone is in the vehicle (including their identity information) or if no one is in the vehicle. Environmental parameter sensors can be combinations of light intensity sensors, position sensors, and altitude sensors. For example, a light intensity sensor detects the intensity of light outside the vehicle and sends this information to the control module, allowing it to determine the vehicle's environment based on light intensity, such as whether it's in a garage (low light intensity) or outdoors (high light intensity). The communication module can communicate with base stations via 5G or other wireless communication protocols, enabling communication with the user's mobile terminal. In-vehicle functional components specifically refer to components with corresponding functions, such as air conditioning, audio-visual entertainment systems, seat massagers, ambient lighting, windows, wipers, and headlights.

[0019] In this embodiment, Figure 1 The extended-range vehicle shown can operate in a rest mode. Specifically, Figure 2 The image shows an application scenario for the nap mode. Figure 2 Let's take an example to illustrate. (Refer to...) Figure 2A user drives a range-extended electric vehicle (REEV) from home to work. The user parks the vehicle in the company's parking lot (e.g., the underground parking lot of the company building, or a parking lot near the company building) and works in the company building. The user's communication terminal can communicate with the REEV. Since there are no charging stations in the parking lot, the user needs to activate the REEV's range extender to charge the battery. In this embodiment, let's assume that at the current time... (Specifically, it could be a certain time on a weekday morning) when the user is at work, and... The following moments (Specifically, it could be sometime around noon on the same day), the user will walk to the parking lot, get into the range-extended vehicle for a short rest, until... The following moments After a short break, I left the range-extended vehicle and returned to work; in order to ensure that users... - Providing a good resting environment during this period allows for better control of the range-extended vehicle. - During this period, the vehicle operates in nap mode. The air conditioning system cools or heats the cabin, maintaining a comfortable temperature and humidity. The infotainment system plays music to promote sleep, the seat massagers provide comfort, and the ambient lighting creates a relaxing atmosphere. These in-vehicle components—air conditioning, infotainment system, seat massagers, and ambient lighting—that provide a good user experience during nap mode are considered nap function components. Components like windshield wipers and headlights, which generally don't operate in nap mode or don't significantly improve the user's nap experience, are not considered nap function components.

[0020] In this embodiment, the user can determine the desired rest function components for use in rest mode based on their own needs, or by using an intelligent recognition algorithm to identify the user's needs, thereby creating a list of rest function components. For example, the user can select the aforementioned air conditioner, audio-visual entertainment system, seat massager, and ambient light to form the list of rest function components. If the user does not wish to use the ambient light in rest mode, they can select the air conditioner, audio-visual entertainment system, and seat massager to form the list of rest function components. In this case, the list of rest function components does not include the ambient light, as the ambient light is not considered a rest function component.

[0021] In this embodiment, the list of rest function components may also include the operating parameters of each rest function component, such as the cooling temperature and fan speed of the air conditioner, the tracks and volume played by the audio-visual entertainment system, the massage intensity and speed of the seat massager, and the brightness and color of the ambient light in rest mode.

[0022] In this embodiment, the start time of the nap mode is The end time of the nap mode is , and Equal times can represent absolute times, such as times expressed using Beijing time.

[0023] In this embodiment, the start time of the nap mode End time The list of rest function components and the working parameters of each rest function component can be packaged into the setting parameters of rest mode.

[0024] In this embodiment, Figure 1 The range-extended electric vehicle shown and Figure 2 Taking the application scenario shown as an example, the rest mode control method applied to range-extended electric vehicles is explained.

[0025] In this embodiment, refer to Figure 3 The nap mode control method applied to range-extended electric vehicles includes the following steps: S1. Detect the environmental information and passenger information of the range-extended vehicle, and determine whether the nap mode is pre-activated or inactive based on the environmental information and passenger information; S2. When the nap mode is pre-activated, obtain the setting parameters of the nap mode; S3. Determine the power generation parameters based on the set parameters; S4. Based on the power generation parameters, control the range extender to generate electricity to charge the battery components; S5. Control the battery components to discharge according to the set parameters, so as to drive the rest function components to work.

[0026] In this embodiment, steps S1-S5 can be executed by the control module in the range-extended vehicle.

[0027] In this embodiment, the time axis involved in steps S1-S5 is as follows: Figure 4 As shown.

[0028] Reference Figure 4 After the user drives their range-extended vehicle to the company's parking lot and parks it, they walk to the company to start work. The current time is... .

[0029] At the present moment The control module executes step S1. In step S1, the control module can call... Figure 1 The environmental parameter sensors in the system detect environmental information of the range-extended electric vehicle and call... Figure 1 The system uses biometric sensors to detect information about occupants in the extended-range electric vehicle (EREV). Environmental information indicates whether the EEV is parked in a garage or in the open, while occupant information indicates whether anyone is currently in the EEV.

[0030] In this embodiment, the range extender is activated to generate electricity by burning fuel during the subsequent execution of step S3. Therefore, to ensure safety, in step S1, if the environmental information indicates that the range extender is parked in a garage, or if the occupant information indicates that there are people in the range extender, the control module determines that the rest mode is inactive. In this case, the control module will not trigger the execution of subsequent steps such as S2-S5, thereby reducing the possibility that the exhaust gas generated by the range extender will accumulate in the garage or the passenger compartment of the range extender and endanger human safety.

[0031] If in step S1, the environmental information indicates that the range-extended vehicle is parked in an open-air parking space, and the occupant information indicates that there are currently no people in the range-extended vehicle, then the control module determines that the rest mode is in a pre-activated state. In this case, the control module will trigger the execution of subsequent steps S2-S5.

[0032] In this embodiment, more judgment conditions can be added to the determination of whether the rest mode is pre-activated or inactive in step S1. For example, judgment conditions such as "currently a workday" and "current location is a company parking lot" can be added. If at least one of the judgment conditions "currently a workday" and "current location is a company parking lot" is not met, it can be determined that the user does not have a need to enter the range-extended vehicle for a rest. In step S1, the control module determines that the rest mode is inactive, so that subsequent steps such as S2-S5 will not be triggered.

[0033] In this embodiment, it is assumed that in step S1, the control module determines that the nap mode is in a pre-activated state and triggers the execution of subsequent steps such as S2-S5.

[0034] In step S2, the user can [do something] at the current time. At that time or at the current moment Previously, the settings, including the start time of the nap mode, were edited using a communication terminal via text input, voice recognition, or gesture recognition. End time The list of rest function components and the operating parameters of each rest function component are sent by the communication terminal to the communication module on the range-extended vehicle. The communication module then sends the received setting parameters to the control module, so that the control module obtains the setting parameters for the rest mode.

[0035] In step S2, the control module can also request authorization from the user's communication terminal to access work software, social media software, and other programs running on the communication terminal. By accessing the work software or social media software, the control module reads information such as chat logs, attendance records, task logs, company announcements, and work documents. Through semantic analysis of this information, it obtains information related to the user's work schedule. This information can be in the format of a correspondence between the user's work activities and time. Through logical reasoning based on this information, it automatically determines the user's daily break time, i.e., the start time of the break mode. and end time Furthermore, by accessing a program running on the communication terminal, the user's personal emotional information for the day can be detected, and based on this information, it can be determined whether the user should participate at the predetermined start time. and end time Based on this, the start / end of the nap mode can be advanced or delayed. For example, if the personal emotional information is "low," the end of the nap mode can be delayed, and the end time can be appropriately postponed. (For example, add 10 minutes to the original time). If the personal emotional information is "good", it is determined that there is no need to start the nap mode earlier or end it later.

[0036] In this embodiment, when the control module executes step S2, which is to obtain the setting parameters of the nap mode, it can specifically perform the following steps: S201. Obtain historical parameters for the nap mode; S202. Generate preset parameters based on historical parameters; S203. Push the preset parameters to the user's communication terminal; S204. Detect the confirmation information for the preset parameters returned by the communication terminal; S205. When a confirmation message is detected, the preset parameters are converted into set parameters.

[0037] In step S201, the historical parameters of the nap mode have the same format as the set parameters, meaning that the historical parameters also include the start time of the nap mode. (Time of day), End time Data such as (time of day), list of rest function components, and working parameters of each rest function component, and the historical parameters are the actual data of rest modes that have been executed in the past.

[0038] In step S202, the control module can use historical parameters as preset parameters, or it can run an intelligent algorithm to adjust the historical parameters to obtain the preset parameters. The format of the preset parameters is the same as that of the historical parameters, and also includes the start time of the nap mode. (Time of day), End time Data such as (time of day), list of rest function components, and operating parameters of each rest function component.

[0039] In step S203, the control module sends preset parameters to the communication module, which then pushes the preset parameters to the user's communication terminal for viewing. The user can confirm or modify the preset parameters, thereby generating confirmation information. If the user chooses to modify the preset parameters, the confirmation information includes the modified preset parameters. The communication terminal sends the confirmation information to the communication module, which then sends the confirmation information to the control module.

[0040] In step S205, after receiving the confirmation information, the control module converts the preset parameters into set parameters. For example, if the confirmation information indicates direct confirmation of the preset parameters, the control module can use the preset parameters as set parameters; if the confirmation information includes preset parameters modified by the user, the control module can use the modified preset parameters as set parameters.

[0041] By performing steps S201-S205, users can be given more choices and usage flexibility, thereby enabling the personalization of the environment for users to take a break and improving the user experience.

[0042] Since the setting parameters obtained in step S2 represent the current time... The following time period - Within the duration of the rest mode, the operating parameters and duration of each rest function component are determined. Therefore, in step S3, the control module can determine the duration of the rest mode based on the set parameters. - Inside, the various rest function components consume a certain amount of electrical energy. Since this energy is provided by the battery components in the range-extended vehicle, the amount of electrical energy consumed before the rest mode is activated (i.e., before the rest mode is activated) is determined. (Before the specified time) the range extender is started to generate electricity to charge the battery components, and the power generation parameters are obtained.

[0043] In this embodiment, the electricity generated by the range extender is determined by its power output and duration. To achieve the highest energy conversion efficiency and reduce harmful gas emissions, the range extender is typically controlled to operate under its optimal conditions. In this case, the range extender's power output is a fixed value. Therefore, the range extender's power output can be taken as the power output at which it achieves optimal efficiency and emissions. The power generation parameters at this point include the start time of the power generation phase. and end time.

[0044] In this embodiment, if the control module has sufficient performance, the control module can [operate] at the current moment. Or the current moment Steps S1-S3 were then executed very quickly. The start time of the power generation phase in the power generation parameters was determined. Then, refer to Figure 4 When the time comes In step S4, the control module controls the range extender to start generating electricity to charge the battery components. The electrical energy output by the range extender is used to charge the battery components, thereby replenishing their power so that the battery components have sufficient electrical energy output to drive the rest mode components after the rest mode is started.

[0045] In this embodiment, refer to Figure 4 When the time comes This refers to the start time of the nap mode. The control module executes step S5, controlling the battery components to discharge according to the set parameters. This causes the battery components to operate on the nap function components determined by the set parameters, providing the user with a comfortable nap environment. This continues until the designated nap time arrives. This refers to the end time of the rest mode. The control module controls the battery components to stop discharging and controls the rest function components to stop working.

[0046] In this embodiment, by executing steps S1-S5, the control module can automatically generate complex parameters such as the setting parameters and power generation parameters for the rest mode. This eliminates the need for complex user operations, enabling intelligent control of the range-extended vehicle's entry and exit from rest mode. Specifically, by determining the power generation parameters based on the setting parameters and controlling the range extender to generate electricity to charge the battery components, the range-extended vehicle's ability to use the range extender for supplemental charging is fully utilized. This allows for pre-charging of the battery components, ensuring they have sufficient power to drive the rest mode function. This reduces the likelihood that the battery will lack sufficient power to operate the rest mode function when the user is taking a rest, ensuring adequate service from the rest mode function and improving user experience. It also reduces the likelihood of the range extender needing to start generating electricity in rest mode, thus reducing the possibility of the user remaining in the range-extended vehicle for extended periods while it is not in motion, thereby mitigating safety risks.

[0047] In this embodiment, when the control module executes step S3, which is the step of determining the power generation parameters based on the set parameters, it can specifically perform the following steps: S301. Determine the power consumption based on the set parameters; S302. Obtain the battery's reserve capacity and remaining capacity; S303. According to the formula Power generation = Guaranteed power generation + Power consumption - Surplus power generation Determine the amount of electricity generated; S304. Set the end time of the power generation phase to the same time as the start time of the rest mode in the set parameters; S305. Obtain the rated power output of the range extender, and determine the duration of the power generation phase based on the rated power output and power generation. S306. Determine the start time of the power generation phase based on the duration and end time of the power generation phase.

[0048] Specifically, when performing step S301, which is the step of determining the power consumption based on the set parameters, the following steps can be performed: S30101. Determine the power consumption of the rest function based on the list of rest function components in the set parameters; S30102. Determine the duration of the rest mode based on the start and end times of the rest mode in the set parameters; S30103. Determine the power consumption of the rest mode based on the duration of the rest mode and the power consumption of the rest function; S30104. Determine the power consumption based on the power consumption of the nap function.

[0049] In step S30101, since the setting parameters include a list of nap function components and their operating parameters, the setting parameters represent the duration of the nap mode. - Within the system, it identifies which rest function components are operating and their operating parameters (such as the cooling temperature of the air conditioner). There is a corresponding relationship between the operating parameters of a rest function component and its power consumption. Therefore, the control module can use methods such as looking up tables to find the power consumption of each rest function component based on its operating parameters, and then sum the power consumption of all rest function components to obtain the total power consumption of all rest function components operating in rest mode, i.e., the power consumption of the rest function.

[0050] In step S30102, the setting parameter itself represents the start time of the nap mode. and end time Therefore, it can be calculated and The difference determines the duration of the rest mode.

[0051] In step S30103, the product of the duration of the nap mode and the power consumption of the nap function can be calculated to obtain the power consumption of the nap function. The power consumption of the nap function represents the duration of the nap mode. - The electrical energy consumed by each of the various rest function components while they are working continuously.

[0052] In step S30104, the power consumption of the rest function itself can be used as the power consumption, that is, the power consumption is equal to the power consumption of the rest function. The power consumption obtained in this way represents the electrical energy required for each rest function component to work continuously.

[0053] In this embodiment, steps S302-S306 will be explained first, taking the example that the power consumption is equal to the power consumption of the nap function.

[0054] In step S302, the reserve capacity of the battery component represents the minimum electrical energy that needs to be retained to ensure the normal operation of the battery component. It can generally be expressed as a percentage of the battery component's capacity, such as 5%. The remaining capacity represents the electrical energy stored in the battery component after the user parks the range-extended vehicle in the parking lot and before the range extender starts generating electricity to charge the battery component. Since the battery component neither charges nor discharges during this stage, it can be assumed that the electrical energy stored in the battery component remains unchanged during this stage, and it can be selected at the current moment. The battery component is charged to obtain the remaining charge; that is, the remaining charge at this moment indicates the battery component's charge level at the current time. The electrical energy stored during operation can be expressed as a percentage of the battery component's capacity.

[0055] Reference Figure 4 Since the remaining power obtained in steps S101-S102 represents the battery component's current state of charge, The amount of electrical energy stored in the battery indicates the duration of the battery's operation in nap mode. - The internal output electrical energy, and the remaining capacity, can indicate the battery's remaining capacity after the nap mode ends (e.g., at a certain time). The minimum amount of electrical energy that needs to be retained, and the required power generation, are indicated by the battery components during the power generation phase (e.g., at time [time]). Then) the electrical energy charged into the battery components will have Surplus electricity + Power generation - Electricity consumption = Reserved electricity supply Therefore, in step S303, it can be achieved through the formula... Power generation = Guaranteed power generation + Power consumption - Surplus power generation The power generation is calculated. Since the guaranteed power supply is a fixed value, the power consumption has been determined in step S301, and the remaining power supply has been determined in step S302, the right side of the formula consists of fixed values, thus the power generation can be calculated.

[0056] Taking into account power generation and charging losses, the loss coefficient can be determined by consulting the range extender's technical parameters. The electrical energy the range extender needs to generate during the power generation phase can then be calculated using the power generation and loss coefficient. In this embodiment, the power generation calculated in step S303, ignoring power generation and charging losses, is taken as an example of the electrical energy the range extender needs to generate during the power generation phase.

[0057] In step S305, the rated power output of the range extender can be determined by querying its technical parameters. Generally, the power output of the range extender under its optimal operating conditions can be taken as the rated power output, which is a fixed value. Since both the power output and the rated power output are known, the power output can be divided by the rated power output to determine the duration of the power generation phase, i.e., the duration for which the range extender needs to generate power to charge the battery components.

[0058] In step S306, the end time of the power generation phase and the start time of the rest mode can be set. The same applies, meaning that the power generation phase is completed just as the rest mode begins, and the range extender has just stopped working when the rest mode starts. This reduces the impact of vibration, noise, and exhaust emissions from the range extender on users when taking a break in the range-extended vehicle.

[0059] Since the duration of the power generation phase has already been determined in step S305, and the end time of the power generation phase is set as... In this case, it can be done at any time Previously determined time Thus, at any time With time The duration between them is equal to the duration of the power generation phase; that is, the power generation phase is a time period. - .

[0060] In this embodiment, the start time of the power generation phase is assumed to be... At the present moment after.

[0061] In this embodiment, refer to Figure 4 By setting the power consumption to equal the power consumption of the rest mode during step S301, and executing steps S302-S306 accordingly, the range extender can be pre-controlled to generate electricity before the rest mode begins. This ensures the range extender outputs sufficient electrical energy to support the operation of all rest mode components, fully utilizing the range extender's ability to supplement power. It pre-charges the battery, ensuring it has the power to drive the rest mode components during rest, reducing the likelihood of insufficient battery power to operate the rest mode components. This ensures the user receives adequate service during rest, improving user experience. It also reduces the likelihood of the range extender needing to start generating electricity during rest, thus minimizing the possibility of the user remaining in the range extender for extended periods when the vehicle is not in motion, reducing safety risks.

[0062] In this embodiment, when executing step S301, the power consumption of the rest function calculated in steps S30101-S30103 can be set to be equal to the power consumption directly, instead of directly setting the power consumption, you can choose to continue executing the following steps.

[0063] Specifically, when performing step S301, which is the step of determining the power consumption based on the set parameters, the following steps can be performed: S30105. Obtain future driving tasks; S30106. Determine the future power consumption based on the future driving task; S30107. Calculate the sum of the power consumption of the nap function and the power consumption of future driving to obtain the total power consumption; S30108. Determine the power consumption based on the total power consumption.

[0064] In step S30105, the future driving task refers to the driving task of the range-extended vehicle after the rest mode ends, for example... Figure 4 In the middle, at the end time of the nap mode Afterwards, users need the range-extended vehicle to be available at all times. The system begins its driving mission, taking the user home. Specifically, the user can set future driving missions, or the control module can automatically generate future driving missions based on the user's historical usage records.

[0065] In step S30106, the control module can first determine the distance of the future driving task, then query the vehicle's energy consumption per kilometer (including the energy consumption of components such as the drive motor, air conditioning, and audio-visual entertainment system), and calculate the future driving power consumption by multiplying the energy consumption per kilometer by the distance of the future driving task. This future driving power consumption represents the electrical energy required for the user to drive the car to perform the future driving task, which will be provided by the battery components during vehicle operation. For example, refer to... Figure 4 This means that the future driving power consumption obtained in this way specifically represents the electrical energy required for a range-extended vehicle to drive from the company parking lot back home.

[0066] In step S30107, the sum of the power consumption of the nap function and the power consumption of future driving is calculated to obtain the total power consumption, that is, the total power consumption is obtained by adding the power consumption of the nap function and the power consumption of future driving.

[0067] In step S30108, the total power consumption obtained in step S30107 can be used as the power consumption required to execute step S301. This power consumption is used for calculation when executing steps S302-S306.

[0068] In this embodiment, the principle of executing steps S30105-S30108 is as follows: the power consumption calculated in steps S30105-S30108 includes not only the electrical energy consumed by the range-extended vehicle in the nap mode (nap function power consumption), but also the electrical energy consumed by the range-extended vehicle in future driving tasks (nap function power consumption). Based on the principle of executing steps S302-S306, by controlling the range extender to generate electricity during the power generation phase, the battery components can be charged with sufficient electrical energy. Without controlling the range extender to generate electricity again, the battery components can not only ensure the execution of the nap mode, but also ensure the execution of future driving tasks, so that the range-extended vehicle has enough electrical energy to complete future driving tasks, and can charge the battery components with mains power at home or other places with charging piles.

[0069] Furthermore, executing steps S30105-S30108 involves controlling the range extender to generate electricity in advance during the power generation phase. This ensures that the battery components store sufficient charge before executing the rest mode and future driving tasks, thereby reducing the likelihood of the range extender restarting to generate electricity during future driving tasks. Since the range-extended vehicle is in a paused state during the power generation phase, the range extender has a higher energy conversion efficiency. However, during future driving tasks, the range-extended vehicle is in a driving state, and the range extender has a lower energy conversion efficiency. Therefore, by executing steps S30105-S30108, a higher energy conversion efficiency of the range extender can be achieved, which helps to save energy and reduce the operating cost of the range-extended vehicle.

[0070] In this embodiment, when executing step S301, for the total power consumption calculated in steps S30105-S30107, it is not necessary to directly set an equal power consumption, but instead, it is possible to continue executing the following steps.

[0071] Specifically, when performing step S301, which is the step of determining the power consumption based on the set parameters, the following steps can be performed: S30109. Detect the current oil level information of the range extender; S30110. Determine the equivalent power consumption based on the current oil quality information; S30111. Obtain the maximum value between the equivalent power consumption and the total power consumption; S30112. Determine the maximum value as the electricity consumption.

[0072] In step S30109, the current fuel information to be detected for the range extender is the fuel level stored in the range extender's fuel tank at the current moment. The average oil quality. In this embodiment, one or more technical indicators for evaluating oil quality in industry standards can be selected, and these technical indicators can be mapped to evaluation indicators applicable to the current oil quality information.

[0073] For example, the technical indicator "gum content" can be selected to obtain the maximum and minimum gum content allowed by industry standards. The maximum gum content represents the maximum amount of gum allowed in fuel to ensure safe and stable combustion in an internal combustion engine, while the minimum gum content represents the minimum amount of gum contained in fuel sold on the market under current production conditions. Since higher gum content indicates lower fuel quality, the maximum gum content can be mapped to 0, and the minimum gum content to 100%. The gum content values ​​between the maximum and minimum gum content can be linearly mapped to values ​​between 0 and 100%. During step S30109, a gum content sensor can be installed in the range extender's fuel tank as a technical indicator sensor to detect the gum content of the fuel stored in the range extender's fuel tank in real time and map it to a value between 0 and 100%, thereby obtaining current fuel quality information.

[0074] For example, the technical indicator "viscosity" can be selected to obtain the maximum and minimum viscosity values ​​allowed by industry standards. The maximum viscosity represents the maximum allowable viscosity of the fuel to ensure proper combustion in the internal combustion engine, while the minimum viscosity represents the minimum viscosity of fuel sold on the market under current production conditions. Since higher fuel viscosity indicates lower fuel quality, the maximum viscosity can be mapped to 0, and the minimum viscosity to 100%. The viscosity values ​​between the maximum and minimum viscosity can be linearly mapped to values ​​between 0 and 100%. During step S30109, a viscosity sensor can be installed in the range extender's fuel tank as a technical indicator sensor to detect the viscosity of the fuel stored in the tank in real time and map it to a value between 0 and 100%, thereby obtaining the current fuel quality information.

[0075] When executing step S30110, the oil reserve quantity can be determined positively based on the current oil quality information. The oil reserve quantity represents the amount of oil that the range extender's tank needs to retain; that is, the higher the current oil quality information (the higher the quality of the oil stored in the range extender), the greater the amount of oil that the range extender's tank needs to retain.

[0076] Specifically, the fuel reserve can be expressed as a percentage of the tank's maximum capacity. For example, a 20% reserve means that 20% of the tank's maximum capacity needs to be retained. A coefficient can be set, and the product of this coefficient and the current fuel quality information is used to calculate the fuel reserve. In this embodiment, this coefficient can specifically be 1, meaning the fuel reserve is equal to the current fuel quality information. For example, if the current fuel quality information is 70%, then the fuel reserve is set to 70%.

[0077] When executing step S30110, the sensor installed in the fuel tank of the range extender is invoked to detect the current fuel level in the fuel tank of the range extender.

[0078] When executing step S30110, if the current fuel level is greater than the reserve fuel level, that is, if the range extender's fuel tank is at the current moment... If the stored fuel level is higher than the fuel level that the tank needs to hold, then the difference between the current fuel level and the required fuel level is calculated. This difference indicates how much fuel the range extender needs to consume to generate electricity if the fuel level in the range extender's tank needs to be reduced to the required fuel level.

[0079] When executing step S30110, the technical parameters of the range extender can be queried to determine its power generation efficiency information. The unit of power generation efficiency information can be kilowatt-hours per liter, indicating how many kilowatt-hours of electricity the range extender can generate for every liter of fuel consumed.

[0080] When executing step S30110, the control module can multiply the difference by the power generation efficiency information to determine the equivalent power consumption. The equivalent power consumption represents how much electrical energy the range extender can generate if it starts generating electricity, causing the range extender to reduce the amount of fuel in the tank to the reserve level (without considering charging losses, it is equal to the electrical energy charged into the battery components during the power generation stage).

[0081] In step S30111, for the total power consumption obtained from steps S30105-S30107 and the equivalent power consumption obtained from step S30110, the maximum value between the equivalent power consumption and the total power consumption is calculated. Maximum value = max(equivalent power consumption, total power consumption) In step S30112, the maximum value calculated in step S30111 is determined as the power consumption to be obtained in step S301.

[0082] In this embodiment, the principle behind steps S30109-S30112 is as follows: In the range extender of a range-extended electric vehicle, the fuel stored in the fuel tank will deteriorate over time, resulting in a decrease in fuel quality. Although range-extended electric vehicles combine the advantages of pure electric vehicles and pure gasoline vehicles, users often prefer to use AC power to charge their range-extended electric vehicles because the cost of charging with AC power is lower than the cost of using gasoline. They tend to avoid using the fuel stored in the fuel tank, which can easily lead to the fuel in the tank being stored for too long and deteriorating in quality, potentially affecting the range-extended electric vehicle. Damage to vehicle components or malfunctions such as inability to start when the range extender is needed; the current fuel quality information detected in step S30109 can quantitatively represent the fuel quality stored in the tank, and the fuel reserve amount is determined positively correlated with the current fuel quality information. This allows for the retention of more fuel when the fuel quality is better, and less fuel when the fuel quality is worse. The equivalent power consumption calculated in step S30110 is the amount of electricity generated by starting the range extender to ensure that the fuel stored in the tank reaches the required fuel reserve amount; if the equivalent power consumption is greater than the total power consumption... The maximum value is the equivalent power consumption, indicating that the equivalent power consumption can cover the total power consumption. In step S30112, the equivalent power consumption is actually determined as the power consumption obtained in step S301. This achieves the same effect as steps S30105-S30108, that is, controlling the range extender to generate power in advance during the power generation stage, so that the battery components store enough power (greater than the total power consumption) before performing the rest mode and future driving tasks, thereby reducing the possibility of starting the range extender to generate power again during the future driving tasks. When the total power consumption is greater than the equivalent power consumption, the maximum value is the total power consumption, indicating that the total power consumption is greater than the equivalent power consumption. The total power consumption can cover the equivalent power consumption. In step S30112, the total power consumption is actually determined as the power consumption obtained in step S301. This can achieve the same effect as the steps S30105-S30108. Moreover, it can also consume the fuel stored in the tank to the reserve level. Therefore, regardless of which one is the maximum value, executing steps S30109-S30112 can achieve the same effect as executing steps S30105-S30108 and consume the fuel stored in the tank to the reserve level. Since the reserve level is positively correlated with the current fuel quality information, it can avoid storing too much poor-quality fuel in the tank.

[0083] Therefore, by executing steps S30109-S30112, the characteristic that the range-extended vehicle can consume fuel when operating in rest mode can be utilized. During the power generation stage before rest mode, the fuel that is easily accumulated during the use of the range-extended vehicle due to long periods of non-use can be consumed, reducing the amount of fuel that has deteriorated due to long-term accumulation. Thus, the rest mode can be used to eliminate the adverse factors of the range-extended vehicle. At the same time, the functions of the range-extended vehicle itself can be used to support the operation of rest mode, thereby helping to reduce the operating cost of the range-extended vehicle and improve the user experience of the range-extended vehicle.

[0084] In this embodiment, a computer device can be used, including a memory and a processor. The memory is used to store at least one program, and the processor is used to load at least one program to execute a nap mode control method applied to a range-extended vehicle, thereby obtaining the effect of a nap mode control method applied to a range-extended vehicle.

[0085] In this embodiment, a computer-readable storage medium can be used, which stores a processor-executable program. When executed by the processor, the processor-executable program is used to perform a nap mode control method applied to a range-extended vehicle, thereby achieving the effect of a nap mode control method applied to a range-extended vehicle.
