[0038] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0040] In the parking scenario, the vehicle's engine is in a stopped state, and the power battery in the vehicle supplies power to various components in the vehicle. If the vehicle functions are used for a long time in the parking scenario, the power battery will be consumed too much, and the power battery will be insufficient or even out of power, affecting the normal use of the subsequent vehicle. In the prior art, if the power battery is not charged, it is necessary to step on the brake and shift gears, switch the vehicle from parking mode to driving mode, run the engine, and then supply power to the power battery, but this method is more cumbersome and cannot quickly start the engine.

[0041] In order to solve the above problems, the present disclosure provides a vehicle control method. Figure 1 A flow chart of a vehicle control method provided by an embodiment of the present disclosure, referring to Figure 1 , the vehicle control method includes S110-S130:

[0042] S110: Determine that the vehicle is in a parking state, and obtain an initial state of charge of the power battery.

[0043] Exemplarily, the vehicle is provided with a power battery, which is a high-voltage battery that can supply power to a low-voltage battery or circuit structure in the vehicle. When the power battery is low on power, the vehicle is prone to lack of energy and power outage. When the vehicle is parked, the motor is stopped and cannot replenish power for the power battery. Therefore, it is necessary to detect the power level of the power battery, determine that the vehicle is parked, and obtain the initial state of charge of the power battery to understand the condition of the power battery. For example, a battery management module is provided in the vehicle, which can detect the power battery and obtain its initial state of charge. It should be noted that the embodiments of the present disclosure do not limit the method for obtaining the initial state of charge of the power battery, and do not limit the specific circuit structure or module.

[0044] S120: Outputting an engine start prompt based on the initial state of charge being less than a preset state of charge.

[0045] Compare the acquired initial state of charge of the power battery with the preset state of charge of the power battery. If the initial state of charge is less than the preset state of charge, it means that the current remaining power of the power battery is low and the power battery needs to be recharged in time. If the power is not recharged in time, continuing to use the power battery in the parking state will affect the health of the power battery. In addition, the vehicle will output an engine start prompt to remind the user of the current state of the power battery and start the generator in time to recharge the power battery. If the initial state of charge is greater than the preset state of charge, it means that the current remaining power of the power battery is sufficient and the power battery can continue to be used in the parking state without recharging the power battery.

[0046] Optionally, the generator start prompt can be output in a variety of ways. For example, a pop-up window on the vehicle's internal display screen can be used to remind the user that the power battery is low and the generator should be started. Alternatively, the user can be prompted by voice, by a buzzer, or by a light, etc. A variety of different prompting methods can be used according to actual needs. The above methods can all achieve the purpose of prompting the user to prevent the user from knowing the power battery status in a timely manner.

[0047] S130: Based on the user's click operation, control the engine to start and prohibit the engine torque output, wherein the click operation is a trigger operation performed by the user on the display screen based on the engine start prompt.

[0048] For example, after the vehicle outputs the engine start prompt, the user can perform a click operation to control the engine start. Among them, a trigger area will be set on the display screen inside the vehicle. After the vehicle outputs the engine start prompt, if the user needs to start the engine, he can click on the corresponding trigger area of ​​the display screen to trigger the corresponding function, control the engine start, and charge the power battery. While controlling the engine start, the engine torque is also disabled to avoid the vehicle switching state and prevent the vehicle from slipping. And there is no need to step on the brake to shift gears, switch the vehicle from parking mode to driving mode, run the engine, and then power the power battery, which greatly simplifies the starting steps.

[0049] In the embodiment of the present disclosure, when the vehicle is in the parking state, if it is determined that the initial state of charge is less than the preset state of charge, it can be considered that the power battery is at risk of running out of power. At this time, an engine start prompt is output to remind the user that the current power battery power is low and should be charged in time. Furthermore, based on the user's click operation, the engine start is controlled and the engine torque output is prohibited. The embodiment of the present disclosure can promptly remind the user to recharge the power battery to avoid battery power loss and affect subsequent normal use, and the user does not need to switch the driving mode by stepping on the pedal and shifting gears to achieve the purpose of starting the engine, which simplifies the steps of starting the engine to charge the power battery.

[0050] Optionally, a pop-up window on the vehicle's display screen will remind the user that the power battery is low, to avoid uncontrolled use of vehicle energy when the vehicle is out of power, which may lead to a problem of low battery. A method of quickly controlling the engine start by clicking is also provided, which does not require key authentication. After the engine is started, the torque output is limited. If the vehicle needs to be driven, it is also necessary to step on the pedal and shift gears for local start.

[0051] In some embodiments, based on the initial state of charge being less than a preset state of charge, outputting an engine start prompt includes:

[0052] The duration during which the initial state of charge is less than the preset state of charge is obtained.

[0053] Based on the duration satisfying the first preset duration, an engine start prompt is output.

[0054] Exemplarily, after obtaining the initial state of charge of the power battery, it is also necessary to count the duration of the initial state of charge being less than the preset state of charge. If the duration meets the first preset duration, the vehicle can be controlled to output the engine start prompt. By counting the duration, it is possible to avoid the situation where the vehicle immediately prompts the user that the power battery is low just after the user gets on the vehicle and has not yet decided how to use the vehicle. For example, the user decides to switch the vehicle to the driving mode. In the driving mode, the engine is in a running state, and the power battery can be charged without additional operations. Even if the initial state of charge of the power battery is less than the preset state of charge, the user does not need to perform other operations. Therefore, if the engine start prompt is output when the user decides to switch the vehicle to the driving mode, it will cause harassment to the user and the user experience will be poor. Alternatively, the user only gets on the vehicle temporarily and will not stay in the vehicle for a long time. Frequent prompts to the user will also cause a bad experience. Considering the above situation, the embodiment of the present disclosure can obtain the duration of the initial state of charge being less than the preset state of charge. When the duration meets the first preset duration, the user is prompted again. For example, the first preset duration is 300s. When the duration reaches 300s, it can be understood that the user has stayed in the car for a long time without adjusting the vehicle status and is less likely to get off the car. At this time, the engine start prompt is output to remind the user that the power battery is low and should be charged in time.

[0055] In some embodiments, before controlling the engine to start and prohibiting the engine torque output, the method further includes:

[0056] Determining that the vehicle state does not satisfy the inhibit start condition;

[0057] Among them, the startup inhibition conditions include at least one of the charging gun being plugged in, the vehicle fuel level not meeting the preset fuel level, and the engine hood not being closed.

[0058] Exemplarily, in consideration of vehicle safety and national standard requirements, the disclosed embodiment also sets a start inhibition condition. When the vehicle meets the start inhibition condition, the operation of controlling the engine start and prohibiting the engine torque output cannot be performed. Among them, the start inhibition condition includes at least one of the charging gun being plugged in, the vehicle fuel level not meeting the preset fuel level, and the engine bonnet not being closed. When the charging gun is plugged in or the bonnet is not closed, the vehicle's engine does not meet the start requirements. For the sake of vehicle safety and user safety, the engine should not be started. When the vehicle's fuel level does not meet the preset fuel level requirement, the vehicle cannot provide enough power to the power battery, and the engine should not be started at this time.

[0059] Therefore, before controlling the engine start and prohibiting the engine torque output, the vehicle status should be obtained and then judged to ensure that the vehicle status does not meet the start inhibition conditions, that is, the vehicle status meets the start conditions, the charging gun is not plugged in, the vehicle fuel level meets the preset fuel level, and the engine cover is closed and other specific requirements, so as to charge the power battery through the engine.

[0060] It should be noted that the embodiments of the present disclosure do not limit the specific content of the start-up inhibition conditions, and may also include other conditions that meet the requirements of national standards to limit whether the engine can be started.

[0061] In some embodiments, it also includes:

[0062] Determine that the vehicle state meets the start inhibition condition, output an engine start failure prompt, and return to execute the operation of determining that the vehicle is in a parking state and obtaining the initial charge state of the power battery.

[0063] For example, if after obtaining the vehicle status, it is determined that the vehicle status meets the start-up inhibition condition, that is, the vehicle status meets at least one of the following conditions: the charging gun is plugged in, the vehicle fuel level does not meet the preset fuel level, and the engine cover is not closed, it means that the current vehicle status does not meet the requirements for starting the engine, and the power battery cannot be charged by starting the engine. At this time, an engine start failure prompt is output, and the operation of determining that the vehicle is in the parking state and obtaining the initial charge state of the power battery is returned to remind the user that the current vehicle status cannot perform the operation of starting the engine, and the vehicle should be checked and adjusted in time. For example, if the engine start fails due to the engine cover not being closed, the user should close the engine cover in time, and the vehicle can obtain the initial charge state of the power battery again, continue the cycle operation, and determine whether the power battery needs to be charged. Among them, when outputting the engine start failure prompt, the corresponding voice prompt can be output according to the actual failure reason, such as: "Unable to start power generation, please remove the charging gun", "Unable to start power generation, please close the engine cover", "Unable to start power generation, low fuel level" and other different prompt contents.

[0064] In some embodiments, controlling the engine to start and prohibiting the engine torque output includes:

[0065] Determine that the vehicle state meets the termination start condition, control the engine to stop running, and return to execute the operation of obtaining the initial charge state of the power battery.

[0066] The termination start condition includes at least one of a local start, an engine failure, and a low-voltage electrical system failure.

[0067] After the engine is started and the engine torque output is prohibited, the engine is in a running state and the power battery is not charged. However, the engine needs to run continuously for a period of time to complete the charging. During this period of time, there may also be some conditions that affect the operation of the engine. These conditions are the termination start conditions. Among them, the termination start conditions include at least one of local start, engine failure, and low-voltage electrical system failure. Local start means that the vehicle state is switched to the driving mode, and the engine is started by stepping on the pedal brake. The vehicle is no longer in the parking state, and there is no need to power the power battery in the manner provided by the embodiment of the present disclosure. The engine failure is a failure of the engine itself. In the case of failure, the engine cannot run to power the power battery. The low-voltage electrical system failure is a failure of the vehicle circuit, and it is also impossible to continue to power the power battery through the engine. In the above cases, the engine cannot continue to run to power the power battery. Therefore, after the engine is started and the engine torque output is prohibited, the vehicle state needs to be detected to determine whether the vehicle state meets the termination start conditions. If the termination start conditions are met, the engine is controlled to stop running, and the operation of obtaining the initial charge state of the power battery is returned to avoid causing more serious safety problems. Among them, if the fault is quickly repaired and resolved, or the vehicle stops local starting and returns to the operation of obtaining the initial charge state of the power battery, it can also continue to execute the relevant steps of controlling the engine start to charge the power battery in the parking state.

[0068] Optionally, if it is determined that the vehicle status does not meet the conditions for terminating the start, the engine may continue to run until the power battery is charged.

[0069] It should be noted that the embodiment of the present disclosure does not limit the specific content of the termination start condition, and other conditions may also be included to limit the termination of engine start.

[0070] In some embodiments, after controlling the engine to start and prohibiting the engine torque output, the method further includes:

[0071] Based on the difference between the current state of charge of the power battery and the initial state of charge of the power battery satisfying a preset difference, the engine is controlled to stop running.

[0072] Controlling the engine start for a long time and prohibiting the engine torque output will lead to incomplete combustion of gasoline, which is easy to produce a large amount of carbon monoxide, resulting in excessive carbon monoxide content in the car, and users are prone to carbon monoxide poisoning in the car. Therefore, the engine running time can be controlled to reduce the carbon monoxide produced. Specifically, by comparing the current state of charge of the power battery with the initial state of charge, the charging status of the power battery is mastered. If the difference between the two meets the preset difference, it is determined that the power battery is fully charged. The power battery can continue to provide the required power for the vehicle function in the parking state. At this time, the engine is controlled to stop running to avoid excessive carbon monoxide caused by continued charging.

[0073] In some embodiments, it also includes:

[0074] Based on the fact that the prompt duration of outputting the engine start prompt meets the second preset duration and the user does not perform a click operation, the vehicle is controlled to enter a power-off state.

[0075] For example, after the engine prompt is output, the prompt duration can also be counted. If the prompt duration meets the second preset duration and the user has not performed a click operation for a long time, it can be understood that the current user does not need to control the engine to start to charge the power battery. In order to protect the safety of the entire vehicle, the vehicle is controlled to enter the power-off state to prevent the vehicle from continuing to maintain the current parking state, resulting in power battery depletion and affecting the life of the power battery. For example, the second preset duration is 30s. If the user still does not click on the display screen to start the engine after more than 30s, the vehicle is controlled to enter the power-off state to protect the safety of the vehicle.

[0076] Exemplarily, the vehicle includes a vehicle display host (Digital Cockpit Head Unit, DHU), a body domain controller (Central Electrical Module, CEM), an engine controller (Engine Control Module, ECM), a display screen, a high-voltage battery controller (Battery Energy Control Module, BECM) and other vehicle systems (such as brakes, keys), etc. The above structure can be used to execute the vehicle control method provided in the embodiment of the present disclosure.

[0077] Specifically, the high-voltage battery controller detects the initial state of charge of the power battery. When the body domain controller determines that the initial state of charge of the power battery is low and less than the preset state of charge, it counts down for 300 seconds. When the countdown ends, the information that the power battery is low is sent to the on-board display host, and the on-board display host controls the vehicle's display screen to output an engine start prompt, such as reminding the user through a pop-up window that the current power battery is low and the engine needs to be started to charge the power battery. And the trigger area will be displayed on the display screen. The user clicks in the trigger area to control the engine start and prohibit the engine torque output. For example, after the user clicks on the display screen, the body domain controller receives the signal and sends a signal to the engine controller to control the engine start, prohibit the engine torque output, and charge the power battery. If the user does not click in the trigger area within 30 seconds, the vehicle will enter the power-off state to protect normal energy.

[0078] It should be emphasized that when the vehicle is of new energy type and can be charged with a charging gun, it is necessary to check multiple times whether the charging gun is inserted for charging. Once the charging gun is inserted, the engine starting conditions specified in the national standards are not met, and the engine should be stopped immediately.

[0079] The present disclosure also provides a vehicle control device, Figure 2 A structural block diagram of a vehicle control device provided by an embodiment of the present disclosure, see Figure 2 The control device includes an acquisition module 21, an output module 22 and a control module 23.

[0080] The acquisition module 21 is used to determine that the vehicle is in a parking state and obtain the initial state of charge of the power battery. The output module 22 is used to output an engine start prompt based on the initial state of charge being less than a preset state of charge. The control module 23 is used to control the engine start and prohibit the engine torque output based on the user's click operation. The click operation is a trigger operation performed by the user on the display screen based on the engine start prompt.
