Description

Technical Field

[0001] The present invention relates to the technical field of hybrid vehicles, and in particular to a hybrid vehicle control method, a hybrid vehicle, and a storage medium. Background Art

[0002] At present, the penetration rate of hybrid electric vehicles (HEV) is increasing year by year. In the related technology, in order to improve the service life of the battery, the battery state of charge (SOC) of the hybrid vehicle will maintain a low power state, such as 20%, during normal driving. The above solution is not suitable for the scenario of driving a hybrid vehicle for outdoor camping, which will result in a very short use time of external camping appliances after the engine is turned off. For example, a 1000W induction cooker can only be used for 20 minutes at a 20% SOC state, which cannot meet the electricity demand for outdoor camping. As a result, users also need to purchase a vehicle-mounted outdoor mobile power supply to meet the electricity demand, resulting in a poor user experience. Summary of the invention

[0003] Based on this, it is necessary to provide a hybrid vehicle control method, device, hybrid vehicle and storage medium to address the above technical problems, so as to solve the problem that the existing technology for maintaining a low-battery state of hybrid vehicles during driving is not suitable for outdoor camping scenarios.

[0006] Determine whether the vehicle has arrived at the destination, and obtain the real-time power level of the vehicle battery;

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

[0008] A hybrid vehicle control device, comprising:

[0009] A forced charging mode switching module, for controlling the vehicle to enter a forced charging mode after the vehicle is in an outdoor camping mode, if a forced charging instruction is received, so as to perform a forced charging operation on the vehicle battery;

[0010] A real-time power acquisition module is used to determine whether the vehicle has arrived at the destination and to acquire the real-time power of the vehicle battery;

[0011] The power retention mode switching module is used to control the vehicle to enter the power retention mode when the real-time power reaches a preset power threshold and the vehicle has not reached the terminal position, so that the vehicle battery maintains the power at the preset power threshold.

[0012] A hybrid vehicle comprises a control module, wherein the control module is used to execute the hybrid vehicle control method as described above.

[0013] A computer-readable storage medium stores computer-readable instructions. When the computer-readable instructions are executed by one or more processors, the one or more processors execute the hybrid vehicle control method as described above.

[0014] In the hybrid vehicle control method of the present invention, when the hybrid vehicle is in outdoor camping mode, after receiving the forced charging instruction, it switches to the forced charging mode to perform forced charging on the vehicle battery, and can timely switch the forced charging mode to the power retention mode when the real-time power of the vehicle battery reaches the preset power threshold and the vehicle has not reached the terminal position. The present invention realizes the intelligent power management of hybrid vehicles based on the above-mentioned logical judgment and strategy control. On the basis of ensuring the normal driving of the vehicle, the hybrid vehicle can forcefully charge the vehicle battery through the forced charging mode before reaching the camping terminal position, so that the vehicle battery can maintain sufficient power when reaching the terminal position to meet the power demand of external electrical appliances during camping, alleviate the power anxiety during outdoor camping, and improve the user experience; at the same time, after the vehicle battery has sufficient power, it will also switch to the power retention mode in time to avoid overcharging of the battery and extend the battery life.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

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

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

[0021] Understandably, the above-mentioned vehicle refers to a hybrid vehicle with a vehicle battery (power battery), and the outdoor camping mode is pre-set. When the vehicle is traveling to outdoor camping (the vehicle can also be set to outdoor camping mode when traveling to other destinations, as long as the user has similar power requirements as outdoor camping, the hybrid vehicle control method can be applied). At this time, the data interaction and logic control of the vehicle navigation system and the battery management system can be realized through the control module of the hybrid vehicle (such as the whole vehicle control module), and then the forced charging instruction is detected in real time to further realize the above-mentioned hybrid vehicle control method. If the hybrid vehicle is not in the outdoor camping mode, it will not detect whether the forced charging instruction is received.

[0022] Among them, the forced charging instruction is an instruction for controlling the vehicle to enter the forced charging mode, and the forced charging mode is a working mode in which the vehicle battery is forced to be charged to increase the power during the driving process of the vehicle. The charging power of the vehicle in the forced charging mode is greater than the discharge power during the driving process. The charging rate of the forced charging mode can be pre-set in combination with the battery safety characteristics. The vehicle activates the forced charging mode when it receives the forced charging instruction, and exits the forced charging mode when the power of the vehicle battery is higher than a specific power threshold.

[0023] It is understandable that the forced charging instruction can be automatically triggered when the preset trigger conditions are met, or it can be manually triggered by the driver or passengers.

[0024] In the scenario where the forced charging instruction is automatically triggered, after the vehicle is in outdoor camping mode, the control module and the on-board navigation system exchange data, and the remaining mileage threshold for triggering the forced charging instruction can be calculated based on the mileage from the camping departure point to the camping destination and the real-time traffic information. The preset trigger condition may refer to the remaining mileage between the vehicle's real-time location and the camping destination (that is, the end location) reaching the remaining mileage threshold. When the preset trigger condition is met, the control module triggers the forced charging instruction, at which time the control module will activate the vehicle's forced charging mode and perform forced charging operations on the vehicle battery.

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

[0026] S20: Determine whether the vehicle has arrived at the destination, and obtain the real-time power level of the vehicle battery.

[0027] Understandably, the destination location is the location of the camping destination, and the control module and the vehicle navigation system exchange data to obtain the real-time location of the vehicle and the location of the camping destination, and determine whether the vehicle has arrived at the destination location. The real-time power refers to the current remaining power of the vehicle battery. The control module and the battery management system exchange data to obtain the real-time power of the vehicle battery.

[0028] S30: When the real-time power level reaches a preset power threshold and the vehicle has not reached the terminal position, control the vehicle to enter a power retention mode so that the vehicle battery maintains the power level at the preset power threshold.

[0029] Understandably, the preset power threshold is a preset critical value of the remaining power for stopping forced charging. In order to maximize the power consumption time of the external electrical appliance, the maximum power percentage can be set as the preset power threshold according to the outdoor camping power demand combined with the battery characteristics, for example, the preset power threshold is set to a SOC state of 70% to 90% (preferably 80%). The power retention mode is a pre-set working mode that keeps the power of the vehicle battery at a specific value. The charging power of the vehicle in the power retention mode is equal to the discharge power during driving, that is, the vehicle is in a charge and discharge balance state. In the forced charging mode, the real-time power of the vehicle battery continues to increase. When the real-time power reaches the preset power threshold, and the vehicle has not yet reached the camping destination, the control module controls the vehicle to exit the forced charging mode and activate the power retention mode. After the vehicle arrives at the camping destination and turns off, the control module can control the vehicle to exit the power retention mode. At this time, the vehicle can be switched to the external power mode at any time to meet the power demand of the user's external camping appliances.

[0030] In this embodiment, when the hybrid vehicle is in outdoor camping mode, after receiving the forced charging instruction, it switches to the forced charging mode to perform forced charging on the vehicle battery, and when the real-time power of the vehicle battery reaches the preset power threshold and the vehicle has not reached the terminal position, the forced charging mode can be switched to the power retention mode in time. The present invention realizes intelligent power management of hybrid vehicles based on the above-mentioned logical judgment and strategy control. On the basis of ensuring the normal driving of the vehicle, the hybrid vehicle can forcefully charge the vehicle battery in the forced charging mode before reaching the camping terminal position, so that the vehicle battery can maintain sufficient power when reaching the terminal position to meet the power demand of external electrical appliances during camping, alleviate the power anxiety during outdoor camping, and improve the user experience; at the same time, after the vehicle battery has sufficient power, it will also switch to the power retention mode in time to avoid overcharging of the battery, so as to improve and extend the battery life.

[0031] In one embodiment, step S10, that is, before receiving the forced charging instruction, includes:

[0032] S101, obtaining the remaining mileage between the real-time position of the vehicle and the destination position;

[0033] S102: When the remaining mileage reaches a preset remaining mileage threshold, a forced charging instruction is generated.

[0034] Understandably, the remaining mileage refers to the distance between the vehicle's current real-time position and the camping destination (i.e., the end point). The control module and the on-board navigation system exchange data to obtain the vehicle's real-time position and the camping destination, as well as the remaining mileage between the real-time position and the end point. The preset remaining mileage threshold is a pre-set critical value used to determine whether the control module automatically triggers a forced charging instruction based on the remaining mileage. When the control module detects that the remaining mileage reaches the preset remaining mileage threshold, a forced charging instruction is automatically generated to control the vehicle to enter the forced charging mode. Under the condition that the road condition information remains unchanged, the vehicle travels the mileage corresponding to the preset remaining mileage threshold in the forced charging mode, and the battery power of the vehicle just reaches the preset power threshold when it reaches the end point.

[0035] This embodiment sets a preset remaining mileage threshold as a judgment condition, which is conducive to accurate monitoring and judgment of the remaining mileage, and then generates a forced charging instruction when the remaining mileage reaches the preset remaining mileage threshold, thereby realizing timely switching to the forced charging mode.

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

[0037] S103: Determine the preset remaining mileage threshold according to the starting position, the ending position, and the initial road condition information from the starting position to the ending position of the vehicle.

[0038] It can be understood that the initial road condition information is the road condition information from the starting position to the end position when the real-time position of the vehicle is at the starting position. The road condition information is the information of the road traffic conditions in the remaining mileage of the vehicle, including factors such as road traffic flow, driving speed, congestion degree, road surface conditions and weather conditions. The vehicle operating conditions of hybrid vehicles are different when driving on different road conditions. According to the power driving conditions of the vehicle battery, they can be divided into pure electric conditions, series conditions and parallel conditions. When the road condition information is a low-speed road condition in the urban area, under the condition that the vehicle speed is low and the power is sufficient, the hybrid vehicle is driven by the motor, that is, the hybrid vehicle is in a pure electric condition. When the road condition information is a congested road condition, under the condition that the vehicle speed is low and the power is insufficient, the hybrid vehicle is driven by the engine-generator-motor, that is, the hybrid vehicle is in a series condition. When the road condition information is a high-speed driving road condition, under the condition that the vehicle speed is high and the power is sufficient, the hybrid vehicle is driven by the engine to provide the main power and the power battery-motor to provide auxiliary power, that is, the hybrid vehicle is in a parallel condition. In an outdoor camping scenario, you will encounter a variety of road conditions alternating from the starting point to the end point.

[0039] When calculating the preset remaining mileage threshold, the premise is that the vehicle is in the forced charging mode during the remaining mileage near the end point, and the vehicle battery is judged to be insufficient before the power of the vehicle reaches the preset power threshold. The vehicle will not be in a pure electric condition to ensure that the charging power is greater than the power consumption. At this time, when the road condition information is a low-speed road condition in the urban area, under the condition that the vehicle speed is low and the power is insufficient, the hybrid vehicle is in a series condition, and the engine charges the vehicle battery through the generator at the same time. When the road condition information is a congested road condition, under the condition that the vehicle speed is low and the power is insufficient, the hybrid vehicle is in a series condition, and the engine charges the vehicle battery through the generator at the same time. When the road condition information is a high-speed driving road condition, under the condition that the vehicle speed is high and the power is insufficient, the hybrid vehicle is in a parallel condition, and the engine charges the vehicle battery through the generator at the same time. When the road condition information is a traffic light road condition, under the condition that the vehicle is idling and the power is insufficient, the engine charges the vehicle battery through the generator.

[0040] In one embodiment, the control module and the vehicle navigation system interact with each other to obtain the vehicle's starting position, end position, and initial road condition information from the starting position to the end position. The control module estimates the battery power of the vehicle when it is driving on the corresponding road condition based on the initial road condition information and historical driving data. A designated vehicle position is selected between the starting position and the end position, and the estimated battery power when the vehicle drives to the designated vehicle position is obtained. Based on the initial road condition information, the corresponding driving power consumption when the vehicle drives from the designated vehicle position to the end position is determined, and the forced charging power is determined according to the corresponding forced charging rate and driving time when the vehicle drives from the designated vehicle position to the end position. The estimated battery power, forced charging power, and driving power consumption are added and subtracted to obtain the end point power. When the end point power is equal to the preset power threshold, the mileage corresponding to the vehicle designated position to the end point is recorded as the preset remaining mileage threshold.

[0041] In this embodiment, when the vehicle sets out, a preset remaining mileage threshold is determined based on the vehicle's starting position, end position, and initial road condition information at the time of departure, so that the preset remaining mileage threshold can be used as a judgment condition for whether to switch to the forced charging mode, which helps to force charging the vehicle battery in a timely manner.

[0042] In one embodiment, in step S10, that is, before receiving the forced charging instruction, the process further includes:

[0043] S104, obtaining real-time road condition information corresponding to the remaining mileage;

[0044] S105, determining the driving charging rate and remaining driving time of the vehicle according to the real-time road condition information;

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

[0046] Understandably, since the traffic volume on the road is constantly changing, and the vehicle may also enter a new route during driving, the real-time traffic information will actually change on the way to the destination. Under the condition that the real-time traffic information changes, the vehicle may reach the preset power threshold before reaching the destination in the mandatory charging mode. The power of the vehicle battery may have reached the preset power threshold before reaching the destination, or the power of the vehicle battery may not reach the preset power threshold after reaching the destination. Therefore, in this embodiment, it is necessary to update the real-time traffic information at a preset time interval, and then update the preset remaining mileage threshold according to the updated real-time traffic information. The preset time interval can be a default setting value, or it can be adjusted as needed. For example, the default setting value is 10s, and the user can adjust it to 5s as needed. The driving charging rate is the rate at which the engine charges the vehicle battery through the generator based on the real-time traffic information. The driving charging rate is not fixed. When the real-time traffic information is a low-speed road condition in the urban area, the driving charging rate is small, and when the real-time traffic information is a high-speed driving road condition, the driving charging rate is large. The remaining driving time is the time required for the vehicle to complete the remaining mileage based on real-time traffic information, including the driving time corresponding to each different road condition and the total driving time.

[0047] In one embodiment, the control module and the vehicle navigation system perform data exchange to obtain real-time road condition information corresponding to the remaining mileage. The updated vehicle designated position is selected between the real-time position and the terminal position, and the estimated battery power when the vehicle travels to the updated vehicle designated position is obtained. Since the premise of calculating the preset remaining mileage threshold is that the vehicle is in the forced charging mode, the driving charging rate is the forced charging rate. Based on the updated real-time road condition information, the driving power consumption corresponding to the vehicle driving from the updated vehicle designated position to the terminal position is determined, and the updated forced charging power is determined according to the driving charging rate and driving time corresponding to the vehicle driving from the updated vehicle designated position to the terminal position. The updated battery estimated power, forced charging power and driving power consumption are added and subtracted to obtain the updated terminal power. When the updated terminal power is equal to the preset power threshold, the mileage corresponding to the updated vehicle designated position to the terminal position is recorded as the updated preset remaining mileage threshold. When the control module detects that the remaining mileage reaches the updated preset remaining mileage threshold, a forced charging instruction is generated, and the update of the preset remaining mileage threshold is stopped at the same time.

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

[0049] In one embodiment, in step S20, that is, after determining whether the vehicle has arrived at the destination and obtaining the real-time power level of the vehicle battery, the process further includes:

[0050] S201. When the real-time power level does not reach a preset power level threshold and the vehicle arrives at the destination, a preset prompt component of the vehicle prompts insufficient power storage information.

[0051] Understandably, the preset prompt component is a vehicle component pre-set for sending prompt information. Depending on the prompt method, the preset prompt component can be a central control screen, instrument panel and windshield with a display function, or a vehicle-mounted speaker with a voice playback function, or a warning light with a warning function. Due to changes in real-time road conditions or changes in the vehicle's driving route, it may happen that when the vehicle reaches the terminal position in the forced charging mode, the battery power of the vehicle does not reach the preset power threshold. In one embodiment, the control module interacts with the vehicle navigation system and the battery management system, and the preset power threshold is 80% of the SOC state. When the vehicle arrives at the terminal position, the battery power of the vehicle is 70% of the SOC state, which does not reach the preset power threshold. At this time, the control module prompts insufficient power storage information through the preset prompt component.

[0052] In this embodiment, when the vehicle arrives at the destination but the real-time power level does not reach the preset power threshold, the user is promptly notified by prompting insufficient power storage information to avoid affecting the user experience due to failure to meet the expected power demand.

[0053] In one embodiment, in step S201, that is, after the preset prompt component of the vehicle prompts the insufficient power storage information, the method further includes:

[0054] S2011, determining the idle charging power according to the real-time power and the preset power threshold;

[0055] S2012, obtaining an idle charging rate, determining an idle charging time according to the idle charging power and the idle charging rate, and prompting the idle charging time through a preset prompt component of the vehicle.

[0056] Understandably, when the vehicle arrives at the destination, the power level of the vehicle battery has not reached the preset power threshold, and the user can choose not to turn off the engine and charge the vehicle battery by driving the generator with the engine when the vehicle is idling until the power level of the vehicle battery reaches the preset power threshold. The idle charging power is the power that needs to be charged when the vehicle is idling, and the idle charging time is the corresponding time required for charging. The idle charging rate is the rate at which the vehicle battery is charged by driving the generator with the engine when the vehicle is idling, and the idle charging rate is usually fixed. The preset prompt component is pre-set. The preset prompt component can be a vehicle component with a display function, including a central control screen, an instrument panel, and a windshield, or it can be a vehicle speaker with a voice playback function, or it can be a warning light with a warning function.

[0057] In one embodiment, the control module and the battery management system interact with each other to determine the idle charging power according to the difference between the real-time power and the preset power threshold, determine the idle charging time according to the idle charging power and the idle charging rate, and display the idle charging time. The user can choose to continue charging in the idle state of the vehicle according to the idle charging time. In addition, since the vehicle has been charged for a certain distance in the forced charging mode before arriving at the terminal position, even if the preset power threshold is not reached, it is far greater than the 20% SOC state during daily driving. Therefore, the user can also choose to turn off the engine directly instead of continuing to charge in the idle state of the vehicle.

[0058] In this embodiment, when the user chooses to continue charging in the vehicle idle state, the idle charging time is determined and displayed, so that the user can choose whether to continue charging in the vehicle idle state according to the needs, thereby improving the user experience.

[0059] In one embodiment, in step S10, that is, before receiving the forced charging instruction, the process further includes:

[0060] S107. When it is detected that a preset forced charging button is triggered, generating the forced charging instruction; 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 for triggering a forced charging instruction, which can be a physical button or a virtual touch screen button. The preset forced charging button can be set on the hybrid vehicle, or on a smart terminal that is connected to the hybrid vehicle for communication. The smart terminal is a terminal device that establishes a communication connection with the control module in advance. The smart terminal includes but is not limited to smart phones, smart watches, and tablet computers. After the vehicle is in outdoor camping mode and before the control module automatically generates a forced charging instruction, the user can manually trigger the forced charging instruction as needed. When the control module detects that the preset forced charging button is triggered, it generates a forced charging instruction and activates the forced charging mode.

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

[0063] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean 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 embodiment of the present invention.

[0064] In one embodiment, a hybrid vehicle control device is provided, and the hybrid vehicle control device corresponds one-to-one to the hybrid vehicle control method in the above embodiment.
