Description

Technical Field

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

[0002] Currently, the popularity of hybrid electric vehicles (HEVs) is increasing year by year. In related technologies, to improve battery lifespan, hybrid vehicles maintain a low state of charge (SOC), such as 20%, during normal driving. This approach is unsuitable for outdoor camping scenarios, as it results in very short usage time for external electrical appliances after the engine is turned off. For example, a 1000W induction cooker at 20% SOC can only be used for 20 minutes, insufficient for outdoor camping power needs. This necessitates the purchase of portable power banks, leading to a poor user experience. Summary of the Invention

[0003] Therefore, it is necessary to provide a hybrid vehicle control method, device, hybrid vehicle, and storage medium to address the aforementioned technical problems, in order to solve the problem that the existing solutions for maintaining a low battery state during hybrid vehicle operation are not suitable for outdoor camping scenarios.

[0004] A hybrid vehicle control method, comprising:

[0005] After the vehicle is in outdoor camping mode, if a forced charging command is received, the vehicle will be controlled to enter forced charging mode to force charge the vehicle battery.

[0006] Determine whether the vehicle has reached the destination and obtain the real-time battery level of the vehicle;

[0007] When the real-time battery level reaches a preset battery threshold and the vehicle has not yet reached the destination, the vehicle is controlled to enter a battery hold mode so that the vehicle battery maintains the battery level at the preset battery threshold.

[0008] A hybrid vehicle control device, comprising:

[0009] The forced charging mode switching module is used to control the vehicle to enter the forced charging mode after receiving a forced charging command when the vehicle is in outdoor camping mode, so as to perform forced charging operation on the vehicle battery.

[0010] The real-time battery power acquisition module is used to determine whether the vehicle has reached the destination and to acquire the real-time battery power of the vehicle.

[0011] The battery hold mode switching module is used to control the vehicle to enter the battery hold mode when the real-time battery level reaches a preset battery threshold and the vehicle has not reached the destination, so that the vehicle battery can maintain the battery level at the preset battery threshold.

[0012] A hybrid vehicle includes a control module for performing the hybrid vehicle control method described above.

[0013] A computer-readable storage medium storing computer-readable instructions that, when executed by one or more processors, cause the one or more processors to perform the hybrid vehicle control method described above.

[0014] In the hybrid vehicle control method of this invention, when the hybrid vehicle is in outdoor camping mode, upon receiving a forced charging command, it switches to forced charging mode to perform forced charging of the vehicle battery. Furthermore, when the real-time battery level reaches a preset threshold and the vehicle has not yet reached the destination, it promptly switches from forced charging mode to battery hold mode. Based on the above logical judgment and strategy control, this invention achieves intelligent battery management for hybrid vehicles. While ensuring normal vehicle operation, it allows the hybrid vehicle to perform forced charging of the battery before reaching the camping destination, ensuring the battery maintains sufficient charge upon arrival to meet the power needs of external electrical appliances during camping, alleviating power anxiety and improving the user experience. Simultaneously, once the battery is fully charged, it promptly switches to battery hold mode to prevent overcharging and extend battery life. Attached Figure Description

Obviously, the drawings described below are only some embodiments of the present invention.

[0017] Figure 2 This is a schematic diagram of a hybrid vehicle control device in one embodiment of the present invention. Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] In one embodiment, such as Figure 1 As shown, a hybrid vehicle control method is provided, including the following steps S10-S30:

[0020] S10. After the vehicle is in outdoor camping mode, if a forced charging command is received, the vehicle is controlled to enter forced charging mode to perform forced charging operation on the vehicle battery.

[0021] Understandably, the aforementioned vehicles refer to hybrid vehicles equipped with a vehicle battery (power battery). The outdoor camping mode is pre-set. During the journey to an outdoor camping destination (or other destinations, the vehicle can be set to outdoor camping mode, as long as the user has similar power needs), the hybrid vehicle can be placed in outdoor camping mode. In this mode, the hybrid vehicle's control module (such as the vehicle control module) can facilitate data interaction and logical control between the in-vehicle navigation system and the battery management system, thereby detecting in real time whether a forced charging command has been received, further implementing the aforementioned hybrid vehicle control method. If the hybrid vehicle is not in outdoor camping mode, it will not detect whether a forced charging command has been received.

[0022] The forced charging command is used to control the vehicle to enter forced charging mode. Forced charging mode is a working mode that forcibly charges the vehicle battery while the vehicle is in motion, increasing its charge level. In forced charging mode, the amount of charge generated during driving exceeds the amount of discharge. The charging rate in forced charging mode can be preset based on battery safety characteristics. The vehicle activates forced charging mode when it receives a forced charging command and exits forced charging mode when the vehicle battery's charge level exceeds a certain threshold.

[0023] Understandably, the forced charging command can be triggered automatically when preset trigger conditions are met, or it can be triggered manually by the driver or passengers.

[0024] In scenarios where a forced charging command is automatically triggered, after the vehicle enters outdoor camping mode, the control module and the in-vehicle navigation system interact. Based on the mileage from the starting point to the camping destination and real-time traffic information, they can calculate the remaining mileage threshold for triggering the forced charging command. The preset trigger condition can be that the remaining mileage between the vehicle's real-time location and the camping destination (i.e., the final location) reaches the remaining mileage threshold. When the preset trigger condition is met, the control module triggers the forced charging command, activating the vehicle's forced charging mode and performing a forced charging operation on the vehicle's battery.

[0025] In scenarios where forced charging is manually triggered by occupants, after the vehicle is in outdoor camping mode but not currently in forced charging mode, occupants can manually trigger the forced charging command as needed. Manually triggered commands include, but are not limited to, button commands, gesture commands, and voice commands.

[0026] S20. Determine whether the vehicle has reached the destination and obtain the real-time battery level of the vehicle.

[0027] Understandably, the destination is the location of the campsite. The control module and the in-vehicle navigation system exchange data to obtain the vehicle's real-time location and the campsite's location, determining whether the vehicle has arrived at the destination. Real-time battery level refers to the current remaining charge of the vehicle's battery. The control module and the battery management system exchange data to obtain the vehicle's real-time battery level.

[0028] S30. When the real-time battery level reaches a preset battery threshold and the vehicle has not reached the destination, control the vehicle to enter a battery hold mode so that the vehicle battery holds the battery level at the preset battery threshold.

[0029] Understandably, the preset battery threshold is a pre-set critical value of remaining battery power before forced charging stops. To maximize the power usage time of external electrical appliances, a maximum percentage of battery power can be set as the preset battery threshold based on the power needs of outdoor camping and battery characteristics. For example, the preset battery threshold can be set to a SOC state of 70%–90% (preferably 80%). The battery hold mode is a pre-set operating mode that maintains the vehicle battery power at a specific value. In battery hold mode, the charging amount of the vehicle during driving is equal to the discharging amount, meaning the vehicle is in a charge-discharge balance state. In forced charging mode, the real-time battery power continuously increases. When the real-time battery power reaches the preset battery threshold, and the vehicle has not yet reached the camping destination, the control module controls the vehicle to exit forced charging mode and activate battery hold mode. After the vehicle reaches the camping destination and is turned off, the control module can control the vehicle to exit battery hold mode. At this time, the vehicle can be switched to external power mode at any time to meet the power needs of the user's external camping appliances.

[0030] In this embodiment, when the hybrid vehicle is in outdoor camping mode, upon receiving a forced charging command, it switches to forced charging mode to perform forced charging of the vehicle battery. Furthermore, when the real-time battery level reaches a preset threshold but the vehicle has not yet reached the destination, the forced charging mode is switched to battery hold mode. This invention achieves intelligent battery management for hybrid vehicles based on the aforementioned logical judgments and strategy control. While ensuring normal vehicle operation, it allows the hybrid vehicle to perform forced charging of the battery before reaching the camping destination, ensuring the battery maintains sufficient charge upon arrival to meet the power needs of external electrical appliances during camping, alleviating power anxiety and improving the user experience. Simultaneously, once the battery is fully charged, it promptly switches to battery hold mode to prevent overcharging and extend battery life.

[0031] In one embodiment, step S10, i.e., before receiving the forced charging command, includes:

[0032] S101. Obtain the remaining driving distance between the real-time location of the vehicle and the destination location;

[0033] S102. When the remaining driving range reaches a preset remaining range threshold, a forced charging command is generated.

[0034] In essence, remaining driving range refers to the distance the vehicle travels from its current real-time location to its camping destination (i.e., the final destination). The control module and the in-vehicle navigation system interact to obtain the vehicle's real-time location, the camping destination location, and the remaining driving range between the real-time location and the final destination. A preset remaining driving range threshold is a pre-set threshold used to determine whether the control module should automatically trigger a forced charging command based on the remaining driving range. When the control module detects that the remaining driving range has reached the preset remaining driving range threshold, it automatically generates a forced charging command to control the vehicle into forced charging mode. Under unchanged road conditions, if the vehicle travels the distance corresponding to the preset remaining driving range threshold in forced charging mode, the battery level will reach the preset threshold level upon reaching the final destination.

[0035] This embodiment uses a preset remaining mileage threshold as a judgment condition, which is conducive to the accurate monitoring and judgment of the remaining driving mileage. Then, when the remaining driving mileage reaches the preset remaining mileage threshold, a forced charging command can be generated to realize the timely switching of the forced charging mode.

[0036] In one embodiment, step S10, i.e., after the vehicle is in outdoor camping mode, includes:

[0037] S103. Determine the preset remaining mileage threshold based on the vehicle's starting position, ending position, and initial road condition information from the starting position to the ending position.

[0038] Understandably, initial road condition information refers to the road conditions from the starting point to the destination when the vehicle's real-time location is at the starting point. Road condition information encompasses the road traffic conditions for the remaining driving distance, including traffic flow, speed, congestion level, road surface conditions, and weather conditions. Hybrid vehicles operate under different conditions depending on the road conditions. Based on the battery's power consumption, these conditions can be categorized into pure electric mode, series mode, and parallel mode. When the road condition is low-speed urban driving, with sufficient battery power, the hybrid vehicle operates using the electric motor, i.e., in pure electric mode. When the road condition is congested, with low speed and insufficient battery power, the hybrid vehicle operates using an engine-generator-motor combination, i.e., in series mode. When the road condition is high-speed driving, with high speed and sufficient battery power, the hybrid vehicle operates primarily using the engine, with the battery and motor providing auxiliary power, i.e., in parallel mode. In outdoor camping scenarios, various road conditions may occur from the starting point to the end point.

[0039] When calculating the preset remaining mileage threshold, the premise is that the vehicle is in forced charging mode for the remaining driving range near the destination. The vehicle is considered low-charged until the battery level reaches the preset threshold, and the vehicle will not operate in pure electric mode to ensure that the charging amount exceeds the electricity consumption. In this case, when the road condition information is low-speed urban traffic, the hybrid vehicle operates in series mode, and the engine charges the battery through the generator. When the road condition information is congested traffic, the hybrid vehicle operates in series mode, and the engine charges the battery through the generator. When the road condition information is high-speed traffic, the hybrid vehicle operates in parallel mode, and the engine charges the battery through the generator. When the road condition information is at a traffic light, the engine charges the battery through the generator while the vehicle is idling.

[0040] In one embodiment, the control module and the in-vehicle navigation system interact to obtain the vehicle's starting position, ending position, and initial road condition information from the starting position to the ending position. The control module estimates the battery charge of the vehicle under the corresponding road conditions based on the initial road condition information and historical driving data. A designated position is selected between the starting and ending positions, and the estimated battery charge is obtained when the vehicle reaches that designated position. Based on the initial road condition information, the driving power consumption from the designated position to the ending position is determined. The forced charging power is determined based on the forced charging rate and driving time from the designated position to the ending position. The estimated battery charge, forced charging power, and driving power consumption are added and subtracted to obtain the final charge level. When the final charge level equals a preset charge threshold, the mileage from the designated position to the ending position is recorded as the preset remaining mileage threshold.

[0041] In this embodiment, when the vehicle departs, a preset remaining mileage threshold is determined based on the vehicle's starting position, ending position, and initial road condition information at the time of departure. This preset remaining mileage threshold is used as a criterion for determining whether to switch to forced charging mode, which helps to force charge the vehicle battery in a timely manner.

[0042] In one embodiment, step S10, i.e., before receiving the forced charging command, further includes:

[0043] S104. Obtain real-time traffic information corresponding to the remaining driving mileage;

[0044] S105. Determine the vehicle's driving charging rate and remaining driving time based on the real-time traffic information.

[0045] S106. Update the preset remaining mileage threshold according to the driving charging rate, the remaining driving time, and the preset battery threshold.

[0046] Understandably, traffic flow is constantly changing, and vehicles may enter new routes during their journey. Therefore, real-time traffic information will change during the trip to the destination. Under these changing conditions, when a vehicle travels to the preset remaining mileage threshold in forced charging mode, the battery level may reach the threshold before reaching the destination, or it may not. Therefore, in this embodiment, real-time traffic information needs to be updated at preset time intervals, and then the preset remaining mileage threshold is updated based on the updated information. The preset time interval can be a default setting or can be adjusted as needed; for example, the default setting is 10 seconds, which can be adjusted to 5 seconds by the user. The driving charging rate is the rate at which the engine charges the vehicle battery through the generator, as confirmed by real-time traffic information. This rate is not fixed; it is lower when the real-time traffic information indicates low-speed urban driving conditions and higher when the real-time traffic information indicates high-speed driving conditions. The remaining driving time is the time required for a vehicle to travel the remaining distance based on real-time traffic information, including the driving time for each different road condition and the total driving time.

[0047] In one embodiment, the control module and the in-vehicle navigation system interact to obtain real-time traffic information corresponding to the remaining driving range. An updated vehicle-designated location is selected between the real-time location and the destination location, and the estimated battery charge when the vehicle reaches the updated vehicle-designated location is obtained. Since the calculation of the preset remaining range threshold assumes the vehicle is in forced charging mode, the driving charging rate is the forced charging rate. Based on the updated real-time traffic information, the driving power consumption corresponding to the vehicle's journey from the updated vehicle-designated location to the destination location is determined. The updated forced charging power consumption is determined based on the driving charging rate and driving time corresponding to the journey from the updated vehicle-designated location to the destination location. The updated estimated battery charge, forced charging power consumption, and driving power consumption are added and subtracted to obtain the updated destination power consumption. When the updated destination power consumption equals the preset power consumption threshold, the mileage from the updated vehicle-designated location to the destination location is recorded as the updated preset remaining range threshold. When the control module detects that the remaining driving range has reached the updated preset remaining range threshold, a forced charging command is generated, and the updating of the preset remaining range threshold is stopped.

[0048] In this embodiment, during vehicle operation, in order to adapt to changes in real-time road conditions corresponding to the remaining driving mileage, the preset remaining mileage threshold is updated to avoid failure to switch to the forced charging mode in a timely manner due to changes in real-time road conditions, thereby improving the accuracy of forced charging mode switching.

[0049] In one embodiment, step S20, after determining whether the vehicle has reached the destination and obtaining the real-time battery level of the vehicle, further includes:

[0050] S201. When the real-time battery level has not reached the preset battery threshold and the vehicle arrives at the destination, the vehicle's preset prompt component will display a message indicating insufficient battery power.

[0051] Understandably, the preset prompt component is a vehicle component pre-set to send prompt information. Depending on the prompting method, the preset prompt component can be a central control screen, instrument panel, or windshield with display function; it can also be a car speaker with voice playback function; or it can be a warning light with warning function. Due to changes in real-time traffic information or changes in the vehicle's driving route, the vehicle battery may not have reached the preset charge threshold when the vehicle reaches its destination in forced charging mode. In one embodiment, the control module interacts with the vehicle navigation system and battery management system. The preset charge threshold is 80% SOC. When the vehicle reaches its destination, the vehicle battery has a 70% SOC, which has not reached the preset charge threshold. At this time, the control module prompts a low charge information message through the preset prompt component.

[0052] In this embodiment, when the vehicle arrives at the destination but the real-time battery level has not reached the preset battery threshold, the user is promptly notified by displaying a low battery information message to avoid affecting the user experience due to the inability to meet expected power demand.

[0053] In one embodiment, step S201, that is, after the vehicle's preset prompt component indicates insufficient battery power, further includes:

[0054] S2011. Determine the idle charging power based on the real-time power level and the preset power threshold.

[0055] S2012. Obtain the idle charging rate, determine the idle charging time based on the idle charging amount and the idle charging rate, and notify the idle charging time through the vehicle's preset reminder component.

[0056] Understandably, if the vehicle's battery level is below the preset threshold when it reaches its destination, the user can choose not to turn off the engine. The engine will drive the alternator to charge the battery while the vehicle is idling until the battery reaches the preset threshold. Idle charging capacity refers to the amount of charge required while the vehicle is idling, and idle charging time refers to the corresponding charging duration. Idle charging rate refers to the rate at which the alternator charges the battery while the vehicle is idling; this rate is typically fixed. Preset warning components are pre-configured. These components can be vehicle components with display functions, including the central control screen, instrument panel, and windshield; they can also be in-car speakers with voice playback capabilities; or they can be warning lights with alert functions.

[0057] In one embodiment, the control module and the battery management system interact to determine the idle charging capacity based on the difference between the real-time battery level and a preset battery threshold. The idle charging time is determined based on the idle charging capacity and the idle charging rate, and is displayed. Users can choose to continue charging while the vehicle is idling based on the idle charging time. Furthermore, since the vehicle has already undergone a certain distance of charging in forced charging mode before reaching its destination, even if the preset battery threshold is not reached, the charge level is still far greater than the 20% SOC (State of Charge) level during normal driving. Therefore, users can also choose to turn off the engine directly instead of continuing charging while the vehicle is idling.

[0058] In this embodiment, when the user selects to continue charging while the vehicle is idling, the idling charging time is determined and displayed, allowing the user to choose whether to continue charging while the vehicle is idling as needed, thus improving the user experience.

[0059] In one embodiment, step S10, i.e., before receiving the forced charging command, further includes:

[0060] S107. When the preset forced charging button is detected to be triggered, the forced charging command is generated; the preset forced charging button is set on the hybrid vehicle or on a smart terminal that is communicatively connected to the hybrid vehicle.

[0061] Understandably, the preset forced charging button is a pre-set button used to trigger a forced charging command. It can be a physical button or a virtual touchscreen button. The preset forced charging button can be located on the hybrid vehicle or on a smart terminal that communicates with the hybrid vehicle. The smart terminal is a terminal device that has established a communication connection with the control module beforehand; smart terminals include, but are not limited to, smartphones, smartwatches, and tablets. After the vehicle enters outdoor camping mode and before the control module automatically generates a forced charging command, the user can manually trigger the forced charging command as needed. When the control module detects that the preset forced charging button has been triggered, it generates a forced charging command and activates the forced charging mode.

[0062] In this embodiment, after the vehicle is in outdoor camping mode and before the control module automatically generates a forced charging command, the user can manually switch the forced charging mode by pressing a button as needed, providing a variety of switching methods.

[0063] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.
