[0021] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0023] Hybrid vehicles operate in forced electric-only mode. When in forced electric-only mode, the vehicle is driven by battery power. When the battery charge falls below a preset threshold, forced electric-only mode is exited, and the engine takes over to drive the vehicle while maintaining charge balance. If the vehicle remains stationary in a cold environment for a period of time, the ambient temperature can affect battery discharge power, reducing driving performance and causing poor acceleration.

[0024] As mentioned above, how to avoid insufficient vehicle power in forced pure electric mode has become an important research issue.

[0025] Based on the above description, if Figure 1 As shown, the vehicle mode control method proposed in this embodiment, the vehicle is a hybrid vehicle, and the vehicle's operating mode includes a forced pure electric mode; the method includes:

[0026] Step 101 : When the vehicle is in the forced pure electric mode, the battery discharge power and required power of the vehicle are obtained.

[0027] In practice, a hybrid vehicle is a vehicle whose drive system is composed of two or more separate drive systems that can operate simultaneously. For example, a hybrid vehicle can be driven by both an engine and an electric motor.

[0028] Hybrid vehicle operating modes include at least one of the following: forced electric mode, intelligent hybrid mode, and electric-first mode. Intelligent hybrid mode primarily ensures vehicle power performance and is most sensitive to the driver's driving needs. It involves the most frequent engine intervention, allowing the engine to provide more power for driving. Electric-first mode consumes more power when the battery is high, is more sensitive to the driver's driving needs, and reduces engine intervention. Forced electric mode uses only electric energy to drive the vehicle when the current battery charge exceeds a pre-set threshold.

[0029] Get the vehicle's battery discharge power P MAX and the required power P CAR , so as to judge whether the battery discharge power meets the user's needs. Among them, the required power P CAR Including drive demand power P DRV and accessory power requirement P AUX The driving power requirement is the power required to drive the vehicle after the high voltage is connected to the vehicle. The accessory power requirement is the power consumed by the vehicle accessories after the high voltage is connected to the vehicle. For example, the accessory power requirement includes at least one of the following: the power required by the vehicle screen, the power required by the air conditioner, and the power required by the lights.

[0030] Step 102: Perform difference processing on the required power and the battery discharge power to obtain a first power.

[0031] In specific implementation, the required power P CAR and battery discharge power P MAX Perform difference processing to obtain the first power P1, which can be P1=P CAR -P MAX , or P1=P MAX -P CAR In this embodiment, it is preferred that P1=P CAR -P MAX .

[0032] Step 103 : Compare the first power with a preset power threshold to obtain a first judgment result, and determine whether to control the vehicle to exit the forced pure electric mode based on the first judgment result.

[0033] During specific implementation, the first power P1 is compared with a preset power threshold P2 to obtain a first judgment result, and whether to exit the forced pure electric mode is determined according to the first judgment result.

[0034] For example, the first power P1=P CAR -P MAXWhen the first power P1 is less than or equal to the power threshold P2, it means that the battery discharge power of the vehicle can meet the user's required power, and the vehicle is controlled to maintain the forced pure electric mode; when the first power P1 is greater than the power threshold P2, it means that the battery discharge power of the vehicle cannot meet the user's required power, and the vehicle is controlled to exit the forced pure electric mode.

[0035] Through the above embodiment, by processing and judging the battery discharge power and the required power, the vehicle's power performance can be judged, and whether to exit the forced pure electric mode can be determined based on the first judgment result, thereby avoiding the problem of insufficient vehicle power in the forced pure electric mode, ensuring that the vehicle's power performance meets user needs, and improving user experience.

[0036] In some embodiments, step 102 includes:

[0037] Step 102A: Obtain the instantaneous acceleration of the vehicle, and compare the instantaneous acceleration with a preset acceleration threshold.

[0038] In practice, the time ranges corresponding to battery discharge power differ between instantaneous acceleration and steady driving. By obtaining the vehicle's instantaneous acceleration and comparing it with a preset acceleration threshold, the system can determine whether the vehicle is in instantaneous acceleration or steady driving.

[0039] Step 102B: In response to determining that the instantaneous acceleration is greater than or equal to the acceleration threshold, performing calculations based on the required power and the first battery discharge power to obtain the first power; wherein the first battery discharge power is the battery discharge power within a first time range.

[0040] In a specific implementation, when the instantaneous acceleration of the vehicle is greater than or equal to the acceleration threshold, the vehicle is in an instantaneous acceleration state, and the battery discharge power of the vehicle in the instantaneous acceleration state is the battery discharge power within the first time range.

[0041] The duration of the first time range is 2s. When the instantaneous acceleration of the vehicle is greater than or equal to the acceleration threshold, the vehicle is in an instantaneous acceleration state. The discharge power of the battery in the instantaneous acceleration state is the battery discharge power P within 2s. MAX_2s .

[0042] Step 102C, in response to determining that the instantaneous acceleration is less than the acceleration threshold, performing calculations based on the required power and the second battery discharge power to obtain the first power; wherein the second battery discharge power is the battery discharge power within a second time range, and the duration of the first time range is less than the duration of the second time range.

[0043] In a specific implementation, when the instantaneous acceleration of the vehicle is less than the acceleration threshold, the vehicle is in a stable driving state, and the battery discharge power of the vehicle in the stable driving state is the battery discharge power within the second time range, where the duration of the first time range is less than the duration of the second time range.

[0044] For example, the duration of the second time range is 10s. When the instantaneous acceleration of the vehicle is less than the acceleration threshold, the vehicle is in a stable driving state, and the discharge power of the battery in the stable driving state is the battery discharge power P within 10s. MAX_10s .

[0045] With this solution, the battery discharge power varies under different vehicle driving conditions. The battery discharge power within a corresponding time range is determined based on the vehicle's driving condition. This improves the accuracy of the battery discharge power determination, ensuring accurate judgment on whether to exit forced electric-only mode.

[0046] In some embodiments, the required power includes: the required driving power and / or the required accessory power; step 102 includes:

[0047] Step 1021: Determine whether a drive request instruction is received.

[0048] In specific implementation, by judging whether a driving request instruction is received, it is determined whether the driver has a driving demand, thereby determining the corresponding required power.

[0049] Step 1022 : In response to determining that the driving request instruction is not received, performing difference processing on the accessory required power and the battery discharge power to obtain the first power.

[0050] In a specific implementation, when no driving request instruction is received, the driver has no driving demand, the required power only includes the accessory required power, and the accessory required power and the battery discharge power are difference processed to obtain the first power.

[0051] Step 1023 : In response to determining that the driving request instruction is received, summing the driving demand power and the accessory demand power to obtain a summed power, and performing difference processing on the summed power and the battery discharge power to obtain the first power.

[0052] In specific implementation, when a driving request instruction is received, the driver has a driving demand, and the required power is the sum of the driving demand power and the accessory demand power. The driving demand power and the accessory demand power are summed to obtain the summed power, and the summed power and the battery discharge power are subtracted to obtain the first power.

[0053] Through the above solution, whether the driver has a driving demand is determined by judging whether a driving request instruction is received, thereby determining the corresponding required power, making the determined required power more accurate.

[0054] In some embodiments, step 1022 includes:

[0055] Step 1022A: Determine the offset of the accessory power requirement.

[0056] Step 1022B: performing difference processing on the accessory required power and the battery discharge power to obtain an initial power.

[0057] Step 1022C: Determine whether the initial power is less than or equal to the offset, and use the initial power as the first power.

[0058] In specific implementations, when the driver has no driving demand, the required power only includes the accessory power demand. In this case, the accessory power demand may be inaccurate. An offset for the accessory power demand is determined, where the offset is within the normal range of the difference between the accessory power demand and the battery discharge power. The difference between the accessory power demand and the battery discharge power is processed to obtain the initial power. If the initial power is less than or equal to the offset, the initial power is used as the first power. If the initial power is greater than the offset, the accessory power demand is excessive, i.e., outside a reasonable range, and the accessory power demand is re-determined.

[0059] In this way, the initial power can be corrected according to the offset to obtain the first power, thereby improving the accuracy of the first power and accurately determining whether to control the vehicle to exit the forced pure electric mode.

[0060] Through the above scheme, by determining the offset of the accessory demand power and thus correcting the first power, the accuracy of the first power can be improved, so as to accurately judge whether to control the vehicle to exit the forced pure electric mode, and avoid the risk of exiting the forced pure electric mode when the current battery power is high and the forced pure electric mode has a high cruising range due to non-user intention.

[0061] In some embodiments, it is characterized in that step 1023 includes:

[0062] Step 1023A: Obtain the required driving torque and average speed of the vehicle, perform multiplication processing based on the required driving torque and the average speed to obtain a first result, and use the ratio of the first result to the proportional coefficient as the first required driving power.

[0063] In specific implementation, the driving demand torque and the average speed are processed to obtain the first driving demand power.

[0064]

[0065] Among them, P DRV1 is the first required driving power, T is the required driving torque, n is the average speed, T×n is the first result, and 9550 is the proportional coefficient. The proportional coefficient can also be 9549 or 9551. In this embodiment, the proportional coefficient is preferably 9550. The proportional coefficient can also be adjusted according to actual conditions.

[0066] Step 1023B: Obtain the current speed of the vehicle, and compare the current speed with a preset speed threshold to obtain a second judgment result.

[0067] In specific implementations, when the vehicle speed is low, the first required driving power may be inaccurately determined. To address this issue, the current vehicle speed is obtained and compared with a preset speed threshold to obtain a second determination result. Based on the second determination result, the required driving power corresponding to the vehicle at different current speeds is determined.

[0068] Step 1023C: In response to determining that the second judgment result is that the current speed is greater than the speed threshold, the first required driving power is used as the required driving power.

[0069] In a specific implementation, when the current speed is greater than the speed threshold, the accuracy of the first required driving power is high, and the first required driving power is used as the required driving power.

[0070] Step 1023D: In response to determining that the second judgment result is that the current speed is less than or equal to the speed threshold, determine the larger power from the first required driving power and a preset second required driving power as the required driving power.

[0071] In specific implementations, when the current speed is less than or equal to a speed threshold, the vehicle's accelerator pedal opening is determined to be greater than or equal to a preset opening threshold, indicating that the vehicle is at a low speed and the driver has a driving demand. In this case, the larger of the first required driving power and the preset second required driving power is taken as the required driving power.

[0072] Through the above solution, the current speed of the vehicle is judged and the corresponding driving demand power is determined according to the current speed, so that the driving demand power is more accurate, ensuring that when the driver has driving demand, it is accurately judged whether the vehicle exits the forced pure electric mode.

[0073] In some embodiments, step 103 includes:

[0074] Step 103A: In response to determining that the first judgment result is that the first power is less than or equal to the power threshold, controlling the vehicle to be in the forced pure electric mode and heating the battery.

[0075] In specific implementation, the required power P CAR and battery discharge power P MAX Perform difference processing to obtain the first power P1, which is P1=P CAR -P MAX .

[0076] When the first power P1 is less than or equal to the power threshold P2, it indicates that the vehicle's battery discharge power can meet the user's power requirement, and the vehicle is controlled to maintain the forced pure electric mode and heat the battery. The battery heating is performed by the vehicle's heater.

[0077] Step 103B: In response to determining that the first judgment result is that the first power is greater than the power threshold, and the first judgment result remains unchanged within a preset time period, controlling the vehicle to exit the forced pure electric mode.

[0078] In specific implementation, when the first power P1 is greater than the power threshold P2 and remains unchanged within a preset time period, it means that the battery discharge power of the vehicle cannot meet the user's required power, and the vehicle is controlled to exit the forced pure electric mode.

[0079] For example, the preset time length is 3 seconds. When the first power P1 is greater than the power threshold P2, and the first judgment result that the first power P1 is greater than the power threshold P2 remains unchanged for 3 seconds, the forced pure electric mode is exited.

[0080] Through the above solution, when the vehicle's battery discharge power meets the user's required power, the vehicle maintains forced pure electric mode and heats the battery, preventing a reduction in battery discharge power due to ambient temperature and minimizing the impact on vehicle power performance. When the vehicle's battery discharge power does not meet the user's required power, the first power is greater than the power threshold and remains unchanged for a preset period of time, avoiding misjudgment and ensuring that the vehicle only exits forced pure electric mode when the battery discharge power fails to meet the user's requirements.

[0081] In some embodiments, step 101 includes:

[0082] Step 101A, obtaining the current battery power.

[0083] Step 101B: determine whether the current battery power is greater than a preset power threshold, and obtain the battery discharge power of the vehicle.

[0084] When implementing it specifically, Figure 2 As shown, Figure 2This is a flowchart of a method for exiting a vehicle's forced pure electric mode according to an embodiment of the present disclosure.

[0085] Before obtaining the vehicle's battery discharge power and judging the battery discharge power, first obtain the current battery power and compare the current battery power with the preset power threshold. When the current battery power is greater than the power threshold, the battery discharge power and the required power are judged. When the current battery power is less than or equal to the power threshold, the forced pure electric mode is exited and the engine intervenes to ensure power and power balance.

[0086] When the required power is less than or equal to the battery discharge power, the battery heater remains on while the vehicle is in forced electric mode. If the required power exceeds the battery discharge power for a period of three seconds, the vehicle exits forced electric mode and the engine starts to drive the vehicle. This ensures that the battery discharge power in forced electric mode meets the vehicle's performance requirements.

[0087] For example, the preset power threshold is 10% of the total battery power. When the current battery power is less than or equal to 10%, the forced pure electric mode is exited; when the current battery power is greater than 10%, the battery discharge power of the vehicle is obtained and the battery discharge power is judged.

[0088] In addition, the exit conditions for forced pure electric mode also include: exiting forced pure electric mode in wading mode, or the user exiting forced pure electric mode by switching the vehicle working mode through the smart cockpit module (Head Up Display, HUT for short).

[0089] Through the above solution, before judging the battery discharge power, the current battery power is judged first to avoid the situation where the battery power is too low to start the forced pure electric mode.

[0090] Through the above embodiment, by processing and judging the battery discharge power and the required power, the vehicle's power performance can be judged, and whether to exit the forced pure electric mode can be determined based on the first judgment result, thereby avoiding the problem of insufficient vehicle power in the forced pure electric mode, ensuring that the vehicle's power performance meets user needs, and improving user experience.

[0091] It should be noted that the method of the embodiments of the present disclosure can be performed by a single device, such as a computer or server. The method of the embodiments of the present disclosure can also be applied in a distributed scenario, where multiple devices cooperate to perform the method.
