Description

Technical Field

[0001] This application relates to the field of vehicles, and more specifically, to a vehicle control method, a vehicle control device, a vehicle, and a storage medium. Background Technology

[0002] With the rapid development of vehicle electronic and electrical systems, the electrical load in vehicles is increasing, leading to a rise in vehicle power consumption. For example, if a user uses onboard electrical devices for an extended period of time when the vehicle is not running, it can easily result in insufficient power reserves, potentially causing the vehicle to become unusable later.

[0003] In related technologies, when the vehicle's battery charge is too low, the user is prompted to charge the vehicle as soon as possible. However, this method only indicates that the vehicle is at risk of running out of power and cannot guarantee a good user experience. Therefore, how to reduce the risk of running out of power while ensuring the vehicle's parking time has become an urgent problem to be solved. Summary of the Invention

[0004] This application provides a vehicle control method, a vehicle control device, a vehicle, and a storage medium, which can reduce the risk of vehicle battery depletion while ensuring the vehicle's parking usage time.

[0005] In a first aspect, a vehicle control method is provided, the method comprising:

[0006] When the vehicle is parked, obtain the first charge level of the power battery and the second charge level of the storage battery in the vehicle.

[0007] Based on the first charge level and the second charge level, a target control strategy for the vehicle is determined, which is used to reduce the vehicle's energy consumption.

[0008] The vehicle is controlled based on the target control strategy.

[0009] The above technical solution, when the vehicle is parked, determines the target control strategy of the vehicle based on the first charge level of the power battery and the second charge level of the storage battery, and controls the vehicle based on the target control strategy. Compared with the prior art that prompts the user to charge the vehicle as soon as possible when the power battery charge is too low, this application determines the target control strategy (energy-saving strategy) that can reduce the vehicle's power consumption based on the first charge level of the power battery and the second charge level of the storage battery. By combining the SOC of the power battery and the SOC of the storage battery, the parking time of the vehicle can be maximized. By reducing the vehicle's power consumption through the target control strategy, the risk of the vehicle running out of power can be reduced while improving the user experience.

[0010] In conjunction with the first aspect, in some possible implementations, the method also includes:

[0011] Obtain the current of the power battery;

[0012] The step of determining the target control strategy for the vehicle based on the first battery level and the second battery level includes:

[0013] If the current indicates that the power battery is in a discharging state, determine whether the vehicle's power preservation function is enabled;

[0014] If the power saving function is off, the target control strategy is determined based on the first power level.

[0015] If the power protection function is enabled, the target control strategy is determined based on the second power level.

[0016] The above technical solution determines whether the vehicle's power-saving function is active when the current current of the power battery indicates that the battery is discharging. If the power-saving function is off, indicating that the high-voltage function is activated, a target control strategy is determined based on the first charge level of the power battery to reduce energy consumption. If the power-saving function is on, indicating that the high-voltage function is off and the low-voltage function is activated, a target control strategy is determined based on the second charge level. By combining the first charge level of the power battery and the second charge level of the battery to determine the target control strategy, the vehicle's parking time can be extended while reducing the risk of battery depletion, thereby improving the user experience.

[0017] In combination with the first aspect and the above implementation methods, in some possible implementation methods, the method further includes: obtaining the drive type of the vehicle;

[0018] The step of determining the target control strategy based on the second power level includes:

[0019] The target control strategy is determined based on the vehicle's drive type and the second battery level.

[0020] The above technical solution determines the target control strategy based on the vehicle's drive type and the second battery level. When the vehicle's power-saving function is activated, it indicates that the vehicle has been connected to high voltage. By using the battery's SOC and the vehicle's drive type, the system aims to maximize the vehicle's parking time and thus improve the user experience.

[0021] In combination with the first aspect and the above implementation methods, in some possible implementation methods, determining the target control strategy based on the vehicle's drive type and the second battery level includes:

[0022] If the drive type is pure electric drive type and the second battery level is less than the first preset battery level, turning off the vehicle power will be determined as the target control strategy.

[0023] If the drive type is a hybrid drive type and the second battery level is less than the second preset battery level, the target control strategy is determined based on the vehicle type of the hybrid drive type, wherein the second preset battery level is less than the first preset battery level.

[0024] The above technical solution specifies that when the vehicle's drive type is pure electric and the second battery level is less than the first preset battery level, shutting off the vehicle's power is determined as the target control strategy. When the vehicle's drive type is hybrid and the second battery level is less than the second preset battery level, the target control strategy is determined based on the hybrid drive type of the vehicle. Since parking charging can only be performed on hybrid vehicles, while pure electric vehicles cannot be parked for charging, the second preset battery level is less than the first preset battery level. For pure electric vehicles, when the battery's SOC is low, the vehicle's power needs to be shut off to ensure normal vehicle use. For hybrid vehicles, when the battery's SOC is low, the target control strategy can be further determined based on the vehicle type, thereby achieving intelligent energy saving of the vehicle, improving the user experience while reducing the risk of battery depletion.

[0025] In combination with the first aspect and the above implementation methods, in some possible implementation methods, determining the target control strategy based on the vehicle type of the hybrid drive type includes:

[0026] If the vehicle type is a first preset model, parking charging will be determined as the target control strategy;

[0027] If the vehicle type is the second preset model, the vehicle's historical energy-saving strategy will be determined as the target control strategy;

[0028] If the vehicle type is the third preset model, turning off the vehicle power will be determined as the target control strategy;

[0029] The energy-saving requirements of the first preset vehicle model are less than those of the second preset vehicle model, and the energy-saving requirements of the second preset vehicle model are less than those of the third preset vehicle model.

[0030] The above technical solution determines parking charging as the target control strategy when the vehicle type is the first preset model, determines the vehicle's historical energy-saving strategy as the target control strategy when the vehicle type is the second preset model, and determines turning off the vehicle's power as the target control strategy when the vehicle type is the third preset model. As the energy-saving requirements of the vehicle type decrease, the vehicle's energy consumption is reduced, which can improve the user experience.

[0031] In combination with the first aspect and the above implementation methods, in some possible implementation methods, the method further includes: if the first battery level is less than a third preset battery level, outputting a prompt message, the prompt message being used to indicate that the vehicle is at risk of running out of battery power;

[0032] The step of determining the target control strategy based on the first power level includes:

[0033] If the first power level is less than the fourth preset power level, shutting down some high-voltage functions will be determined as the target control strategy.

[0034] If the first power level is less than the fifth preset power level, shutting down all high-voltage functions will be determined as the target control strategy.

[0035] Wherein, the fifth preset power level is less than the fourth preset power level, and the fourth preset power level is less than the third preset power level.

[0036] The above technical solution involves outputting a warning message when the first charge level of the power battery is less than the third preset charge level, indicating a risk of the vehicle running out of power. When the first charge level of the power battery is less than the fourth preset charge level, shutting down some high-voltage functions is identified as the target control strategy. When the first charge level of the power battery is less than the fifth preset charge level, shutting down all high-voltage functions is identified as the target control strategy. Since the fifth preset charge level is less than the fourth preset charge level, and the fourth preset charge level is less than the third preset charge level, as the state of charge (SOC) of the power battery gradually decreases, the strength of the target control strategy (energy-saving strategy) to reduce the vehicle's energy consumption gradually increases. Thus, by controlling the vehicle through the target control strategy, the risk of the vehicle running out of power can be reduced.

[0037] In combination with the first aspect and the above implementation methods, in some possible implementation methods, the method further includes: determining whether a user is present in the vehicle;

[0038] The step of determining the target control strategy for the vehicle based on the first battery level and the second battery level includes:

[0039] If the user is present in the vehicle, the target control strategy is determined based on the first battery level and the second battery level.

[0040] If the user is not in the vehicle, determine whether all the doors in the vehicle are closed. If all the doors in the vehicle are closed, control the vehicle to lock and turn off the vehicle power.

[0041] The above technical solution, when there is no user in the vehicle, determines whether all vehicle doors are closed. If all doors are closed, it controls the vehicle to lock and shuts off the power. Conversely, if there is no user in the vehicle and all doors are closed, indicating the user forgot to lock the vehicle, it controls the vehicle to lock and shuts off the power, thus reducing energy consumption and ensuring normal vehicle use. When there is a user in the vehicle, a target control strategy is determined based on a first and second battery charge level. By using the first charge level of the power battery and the second charge level of the storage battery, the vehicle's usage time while parked can be ensured, thereby improving the user experience.

[0042] Secondly, a vehicle control device is provided, the vehicle control device comprising:

[0043] The acquisition module is used to acquire the first charge level of the power battery and the second charge level of the storage battery in the vehicle when the vehicle is in a parked state.

[0045] A control module is used to control the vehicle based on the target control strategy.

[0046] In conjunction with the second aspect, in some possible implementations, the acquisition module is also used for:

[0047] Obtain the current of the power battery;

[0048] The module is specifically used for:

[0049] If the current indicates that the power battery is in a discharging state, determine whether the vehicle's power preservation function is enabled;

[0050] If the power saving function is off, the target control strategy is determined based on the first power level.

[0051] If the power protection function is enabled, the target control strategy is determined based on the second power level.

[0052] In combination with the second aspect and the above implementation methods, in some possible implementation methods, the acquisition module is further configured to: acquire the drive type of the vehicle;

[0053] The module is specifically used for:

[0054] The target control strategy is determined based on the vehicle's drive type and the second battery level.

[0055] Combining the second aspect and the above implementation methods, in some possible implementation methods, the module is specifically used for:

[0056] If the drive type is pure electric drive type and the second battery level is less than the first preset battery level, turning off the vehicle power will be determined as the target control strategy.

[0057] If the drive type is a hybrid drive type and the second battery level is less than the second preset battery level, the target control strategy is determined based on the vehicle type of the hybrid drive type, wherein the second preset battery level is less than the first preset battery level.

[0058] Combining the second aspect and the above implementation methods, in some possible implementation methods, the module is specifically used for:

[0059] If the vehicle type is a first preset model, parking charging will be determined as the target control strategy;

[0060] If the vehicle type is the second preset model, the vehicle's historical energy-saving strategy will be determined as the target control strategy;

[0061] If the vehicle type is the third preset model, turning off the vehicle power will be determined as the target control strategy;

[0062] The energy-saving requirements of the first preset vehicle model are less than those of the second preset vehicle model, and the energy-saving requirements of the second preset vehicle model are less than those of the third preset vehicle model.

[0063] Combining the second aspect and the above implementation methods, in some possible implementation methods, the module is specifically used for:

[0064] If the first battery level is less than the third preset battery level, a prompt message is output, which is used to indicate that the vehicle is at risk of running out of power.

[0065] If the first power level is less than the fourth preset power level, shutting down some high-voltage functions will be determined as the target control strategy.

[0066] If the first power level is less than the fifth preset power level, shutting down all high-voltage functions will be determined as the target control strategy.

[0067] Wherein, the fifth preset power level is less than the fourth preset power level, and the fourth preset power level is less than the third preset power level.

[0068] Combining the second aspect and the above implementation methods, in some possible implementation methods, the module is specifically used for:

[0069] Determine whether a user is in the vehicle;

[0070] If the user is not in the vehicle, determine whether all the doors in the vehicle are closed. If all the doors in the vehicle are closed, control the vehicle to lock and turn off the vehicle power.

[0080] Figure 6 This is a schematic diagram of the structure of a vehicle provided in an embodiment of this application. Detailed Implementation

[0081] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0082] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0083] With the rapid development of vehicle electronic and electrical systems, the electrical load in vehicles is increasing, leading to a rise in vehicle power consumption. For example, if a user uses onboard electrical devices for an extended period of time when the vehicle is not running, it can easily result in insufficient power reserves, potentially causing the vehicle to become unusable later.

[0084] Figure 1 This is a schematic diagram of a vehicle control method provided in an embodiment of this application.

[0085] For example, such as Figure 1 As shown, when vehicle 100 is parked and the battery power in vehicle 100 is low, a prompt message will be displayed on screen 110 to remind the user to charge vehicle 100 as soon as possible. For example, the prompt message may be "Vehicle battery power is low, please charge it in time".

[0086] However, simply indicating the battery level to prompt users to charge quickly only alerts them to the risk of a depleted battery. If the vehicle is used for an extended period without being driven and is not charged promptly, the entire vehicle is at risk of running out of power, potentially rendering it unusable. This risk is even higher for commercial vehicles, where customers often need to rest for extended periods.

[0087] In view of this, this application provides a vehicle control method, a vehicle control device, a vehicle, and a storage medium. This method can add software control logic without changing the existing hardware design to implement a power-saving protection strategy for high and low voltage power supplies, meeting the user's needs in long-term rest driving scenarios. That is, it can reduce the risk of vehicle power depletion while ensuring the vehicle's parking time.

[0088] Figure 2 This is a schematic diagram of the framework of a vehicle control system provided in the embodiments of this application.

[0089] For example, such as Figure 2 As shown, the vehicle control system 200 includes a Telematics Box (TBOX) 210, a mobile APP 211, a Gateway (GW) 220, a Head Unit (HUT) 221, an instrument panel screen 222, an in-vehicle camera 223, a Body Domain Module (BDM) 230, a Vehicle Integrated Unit (VIU), a seat sensor 232, a sleeper berth sensor 233, a battery 234, a Powertrain Integration Unit (PIU) 240, a compressor 241, an air compressor 242, a steering pump 243, and a Battery Management System (BMS).

[0090] The TBOX210 interacts with the mobile app 211 via a 4G / 5G network and with the GW220 via a Controller Area Network with Flexible Data Rate (CANFD). The GW220 interacts with the HUT221, BDM230, and PIU240 via CANFD. The HUT221 displays information and interacts with the instrument panel 222 and the in-vehicle camera 223 via Low Voltage Differential Signaling (LVDS). The BDM230 primarily manages the power supply of the low-voltage power system and interacts with the VIU231 via the Controller Area Network (CAN). The VIU231 collects battery information from the battery 234 via the Local Interconnect Network (LIN) and is responsible for data acquisition from the seat sensor 232 and the sleeper sensor 233. The PIU240 is mainly responsible for the power management function of the high-voltage system. It interacts with the BMS244 via CAN to collect battery information of the power battery and is responsible for the data acquisition of the compressor 241, air compressor 242 and steering pump 243.

[0091] For example, when the vehicle's high-voltage power system is powered on, the vehicle is not ready, the vehicle speed is 0 km / h, and the vehicle is in P gear, the seat sensor, sleeper sensor, and in-vehicle camera are used as data acquisition units to collect in-vehicle data. The data is then used to determine whether there is anyone in the vehicle. When there is no one in the vehicle, all doors are closed, and the vehicle is not in an over-the-air (OTA) upgrade state, a prompt message "Vehicle unlocked" is sent, and an alarm message is pushed to the mobile APP via TBOX so that the user is aware that the vehicle is unlocked and can lock it in time. If the user does not respond within 60 seconds (which can be calibrated), the BDM will shut down the vehicle power and control the vehicle to lock, and then the vehicle will enter a sleep state.

[0092] When someone is in the vehicle, it indicates that the user needs to park and use the vehicle. The PIU monitors the state of charge (SOC, or remaining battery power) of the high-voltage system in real time. When the SOC of the power battery is lower than a preset threshold (which can be calibrated), the target control strategy (energy-saving strategy) is implemented in three levels.

[0093] Level 1: When the SOC of the power battery is less than 35% and the battery pack current is greater than -1A, it indicates that the vehicle is in a discharging state and the remaining power battery charge is low. The PIU sends the first prompt message to the instrument panel screen, central control screen, and mobile APP to remind the user to charge as soon as possible. For example, the first prompt message is "The SOC of the power battery is low, please charge it in time".

[0094] Level Two: When the SOC of the power battery is less than 30% and the battery pack current is greater than -1A, it indicates that the vehicle is in a discharging state and the remaining power battery charge is low, requiring a reduction in the vehicle's energy consumption. The PIU sends a second prompt message to the instrument panel screen, central control screen, and mobile app to remind the user to charge the battery as soon as possible and to shut down some high-voltage functions of the vehicle. For example, the second prompt message might be "Power battery SOC is low, some high-voltage functions in the vehicle will be shut down soon." After sending the second prompt message, the PIU controls the shutdown of the motor drive system power, air conditioning system power, steering system power, and air compressor power, leaving only the DC-DC converter power on (or on).

[0095] Level 3: When the SOC of the power battery is less than 25% and the battery pack current is greater than -1A, it indicates that the vehicle is in a discharging state and the remaining power battery charge is extremely low, requiring minimizing the vehicle's energy consumption. The PIU sends a third prompt message to the instrument panel screen, central control screen, and mobile app, advising the user to charge the battery as soon as possible and turn off all high-voltage functions. For example, the third prompt message might be "Power battery SOC too low, high-voltage system about to shut down." After sending the third prompt message, the PIU controls the high-voltage system to shut down and sends a message to activate the vehicle's power preservation function. At this time, the instrument panel screen illuminates a red (calibrable) charging alarm indicator. For example, the alarm indicator message might be "Battery charging shut down, vehicle at risk of power depletion."

[0096] To reduce vehicle energy consumption, HUT disables the parking charging function (charging while the vehicle is parked) by default. Users can change the parking charging status through the vehicle's screens (such as the central control screen, entertainment screen, etc.). It's understandable that the parking charging function is only effective for hybrid vehicles. Its principle is that when the vehicle is parked, a transmitter charges the battery to increase driving range or optimize battery condition. Pure electric vehicles can only be charged via an external charging gun.

[0097] When the hybrid vehicle's parking charging is enabled, the BDM (Battery Management Device) monitors the battery's State of Charge (SOC) upon receiving a power-saving signal (this can be determined directly by the SOC or by the battery voltage). If the battery voltage is less than 24.5V or the SOC is less than 50%, and the vehicle is in a park position (ignition switch ON), at 0 km / h, in Park (P), with the DC-DC converter off, the smart key inside the vehicle, and after successful anti-theft authentication, the BDM sends a start request. The PIU (Power Intake Unit) controls the high-voltage system to power on, starting the engine for parking charging. Further, the BDM checks if the engine speed is greater than 500 rpm and the battery pack current is less than or equal to -1A. If the engine speed is less than or equal to 500 rpm or the battery pack current is greater than -1A, the parking charging function fails to activate, the BDM shuts off the vehicle's power, and the vehicle enters a sleep state. If the engine speed is greater than 500 rpm and the battery pack current is less than or equal to -1A, the parking charging function successfully activates, and the vehicle begins parking charging.

[0098] When the parking charger of a hybrid vehicle is off, or when the vehicle is a pure electric vehicle, the BDM (Battery Management Device) sends a prompt message to the instrument panel, central control screen, and mobile APP when it receives a power protection information (power protection function is on) and the battery voltage is less than 25.1V or the battery SOC is less than 70%. Upon receiving a user's control command, the BDM controls the vehicle according to the control command. If no user control command is received within 20 seconds, the BDM controls the vehicle's low-voltage power system to shut down, and the vehicle enters a sleep state.

[0099] The aforementioned technical solution reduces vehicle energy consumption through different levels of energy-saving strategies. Specifically, it shuts off the high-voltage system power only when necessary, ensuring a good user experience while minimizing energy consumption. Furthermore, without altering the existing hardware design, adding software control logic enables energy-saving protection strategies for both high and low voltage power supplies. These energy-saving protection strategies (or target control strategies) maximize vehicle parking time and further reduce the risk of battery depletion.

[0100] Figure 3 This is a schematic flowchart of a vehicle control method provided in an embodiment of this application.

[0101] For example, Figure 3 The method shown can be executed by the vehicle's body domain controller or chip.

[0102] For example, such as Figure 3 As shown, the vehicle control method 300 includes the following processes:

[0103] S310: When the vehicle is parked, it obtains the first charge level of the power battery and the second charge level of the storage battery.

[0104] For example, the parking status indicates that the vehicle is powered on but not in motion. For instance, the parking status means that the vehicle's electrical system and high-voltage power system are activated, the electronic devices and battery management system are in operation (i.e., the vehicle is in the ON position), the vehicle is not in motion, and it is in the P position.

[0105] It should be noted that the first charge level of the power battery in a vehicle indicates the remaining charge of the power battery (or the state of charge of the power battery), while the second charge level of the storage battery indicates the remaining charge of the storage battery (or the state of charge of the storage battery).

[0106] For example, when the vehicle is parked and the high-voltage power system is activated, the first charge level of the power battery is monitored in real time. When the first charge level of the power battery indicates a low charge level, the high-voltage function of the vehicle is turned off (vehicle de-high voltage) and the low-voltage power system is activated. The second charge level of the battery is monitored in real time. When the second charge level of the battery indicates a low charge level, the vehicle power is turned off to ensure the availability of subsequent vehicles.

[0107] S320 determines the target control strategy for the vehicle based on the first and second battery levels.

[0108] For example, a target control strategy (or energy-saving strategy) is used to reduce the vehicle's electrical energy consumption. By controlling the vehicle through the target control strategy, the vehicle's electrical energy consumption can be reduced, thereby increasing the parking time.

[0109] In one example, when the vehicle is parked, the first charge level of the power battery and the second charge level of the storage battery are obtained. Based on the first charge level of the power battery and the second charge level of the storage battery, a target control strategy to reduce the vehicle's energy consumption is determined, so as to control the vehicle through the target control strategy.

[0110] In another example, when the vehicle is parked, it is determined whether a user is inside the vehicle. If no user is inside, it is determined whether all the vehicle doors are closed. If all the doors are closed, the vehicle is locked and the power is turned off. When a user is inside, the first charge level of the vehicle's power battery and the second charge level of the storage battery are obtained. Based on the first charge level of the power battery and the second charge level of the storage battery, a target control strategy to reduce the vehicle's energy consumption is determined.

[0111] Specifically, when the vehicle is parked, a T0 timer (e.g., 120 seconds, calibrable) is started. After the T0 timer, in-vehicle data is collected via an in-vehicle camera, seat sensors, and sleeper berth sensors. Based on this data, it is determined whether a user is in the vehicle. If a user is present, a target control strategy is determined based on the first charge level of the power battery and the second charge level of the storage battery. If no user is present, it is determined whether all vehicle doors are closed. If any door is open, the vehicle status continues to be monitored until all doors are closed or the vehicle is in motion. When all doors are closed, a locking prompt is sent so that the user can lock the doors and power off the vehicle.

[0112] For example, if the vehicle lock prompt message is "Vehicle unlocked," a T3 timer (e.g., 60 seconds, calibrable) is started after outputting the prompt message. When the user issues a lock command within the T3 timer, the vehicle is locked and powered off. When the T3 timer expires, the prompt count is accumulated once, and the lock prompt message is re-outputted. When the user issues a lock command within the T3 timer, the vehicle is locked and the power is turned off. When the T3 timer expires, it is determined whether the prompt count is greater than 3 (calibrable). If the prompt count is greater than 3, the vehicle is locked and the power is turned off. If the prompt count is less than or equal to 3, the lock prompt message is re-outputted, and subsequent steps are executed.

[0113] The above technical solution, when there is no user in the vehicle, determines whether all vehicle doors are closed. If all doors are closed, it controls the vehicle to lock and shuts off the power. Conversely, if there is no user in the vehicle and all doors are closed, indicating the user forgot to lock the vehicle, it controls the vehicle to lock and shuts off the power, thus reducing energy consumption and ensuring normal vehicle use. When there is a user in the vehicle, a target control strategy is determined based on a first and second battery charge level. By using the first charge level of the power battery and the second charge level of the storage battery, the vehicle's usage time while parked can be ensured, thereby improving the user experience.

[0114] The method described in the following embodiments can be used as a refinement of the target control strategy for reducing power consumption based on the first charge of the power battery and the second charge of the storage battery.

[0115] For example, when the vehicle is parked, the current current of the power battery, the first charge level of the power battery, and the second charge level of the storage battery are obtained. When the current current indicates that the power battery is in a discharging state, it is determined whether the vehicle's power protection function is in the active state. When the vehicle's power protection function is in the inactive state, the target control strategy is determined based on the first charge level of the power battery; when the vehicle's power protection function is in the active state, the target control strategy is determined based on the second charge level of the storage battery.

[0116] Specifically, the system acquires the current current of the power battery, its initial charge level, and the second charge level of the storage battery. It then determines whether the current current indicates the power battery is in a discharging state. If the current current indicates the power battery is charging, the vehicle is not at risk of running out of power. If the current current indicates the power battery is discharging, the system checks if the vehicle's power-saving function is active. If active, the high-voltage function is off (low-voltage function is off), battery charging is stopped, and the low-voltage function is activated. Based on the second charge level of the storage battery, a target control strategy is determined to reduce the vehicle's energy consumption. If active, the high-voltage function is off, indicating the high-voltage function is activated. Based on the first charge level of the power battery, a target control strategy is determined to reduce the vehicle's energy consumption.

[0117] The above technical solution determines whether the vehicle's power-saving function is active when the current current of the power battery indicates that the battery is discharging. If the power-saving function is off, indicating that the high-voltage function is activated, a target control strategy is determined based on the first charge level of the power battery to reduce energy consumption. If the power-saving function is on, indicating that the high-voltage function is off and the low-voltage function is activated, a target control strategy is determined based on the second charge level. By combining the first charge level of the power battery and the second charge level of the battery to determine the target control strategy, the vehicle's parking time can be extended while reducing the risk of battery depletion, thereby improving the user experience.

[0118] In one example, when the vehicle's power-saving function is off, it indicates that the high-voltage function in the vehicle is activated. When the first power level is less than the third preset power level, a prompt message is output to indicate that the vehicle is at risk of running out of power. When the first power level is less than the fourth preset power level, shutting down some high-voltage functions is determined as the target control strategy. When the first power level is less than the fifth preset power level, shutting down all high-voltage functions is determined as the target control strategy.

[0119] Optionally, the third preset battery level is 35%, 33%, 31%, etc. The third preset battery level can be determined according to the actual situation, and no specific limitation is made here.

[0120] Optionally, the fourth preset battery level is 30%, 28%, 26%, etc. The fourth preset battery level can be determined according to the actual situation, and no specific limitation is made here.

[0121] Optionally, the fifth preset battery level is 25%, 23%, 21%, etc. The fifth preset battery level can be determined according to the actual situation, and no specific limitation is made here.

[0122] It should be noted that the fifth preset battery level is less than the fourth preset battery level, and the fourth preset battery level is less than the third preset battery level. For example, when the third preset battery level is 35%, the fourth preset battery level is 30%, and the fifth preset battery level is 25%.

[0123] For example, when the vehicle's battery protection function is off, the system checks if the initial charge level of the power battery is less than 35% (the third preset charge level). If the initial charge level is greater than or equal to 35%, the system determines that the power battery's State of Charge (SOC) is high. If the initial charge level is less than 35%, a prompt message is output. For example, the prompt message could be "Power battery SOC is low, please charge it promptly," to alert the user that the vehicle is at risk of running out of power and needs to be charged.

[0124] The system continuously monitors the initial charge level of the power battery. If the initial charge level falls below 30% (the fourth preset charge level), a target control strategy is established to shut down some high-voltage functions (such as the motor drive system, air conditioning system, steering system, and air compressor). For example, when the initial charge level of the power battery is less than 30%, the system outputs a message on the instrument panel, central control screen, and mobile app stating "Power battery SOC is low, some high-voltage functions will be shut down soon." After this message is displayed, the system controls the vehicle to shut down some high-voltage functions.

[0125] Furthermore, the system continuously monitors whether the initial charge level of the power battery is less than 25% (the fifth preset charge level). When the initial charge level of the power battery is less than 25%, the system sets shutting down all high-voltage functions as the target control strategy and controls the shutdown of all high-voltage functions. For example, when the initial charge level of the power battery is less than 25%, the system outputs "Power battery SOC is low, all high-voltage functions will be shut down soon" through the instrument panel screen, central control screen, and mobile APP. After outputting the prompt message, the system controls the vehicle to shut down all high-voltage functions.

[0126] The above technical solution involves outputting a warning message when the first charge level of the power battery is less than the third preset charge level, indicating a risk of the vehicle running out of power. When the first charge level of the power battery is less than the fourth preset charge level, shutting down some high-voltage functions is identified as the target control strategy. When the first charge level of the power battery is less than the fifth preset charge level, shutting down all high-voltage functions is identified as the target control strategy. Since the fifth preset charge level is less than the fourth preset charge level, and the fourth preset charge level is less than the third preset charge level, as the state of charge (SOC) of the power battery gradually decreases, the strength of the target control strategy (energy-saving strategy) to reduce the vehicle's energy consumption gradually increases. Thus, by controlling the vehicle through the target control strategy, the risk of the vehicle running out of power can be reduced.

[0127] Furthermore, after shutting down all high-voltage functions in the vehicle, a T1 timer (e.g., 20 seconds, calibrable) is started. The current of the power battery is then monitored to determine if the battery is discharging. When the battery is charging, it indicates that the battery is currently charging and the vehicle is not at risk of running out of power. When the battery is discharging, the vehicle's power-saving function is activated (the vehicle's power-saving function is activated after the high voltage is turned off), and a red charging alarm indicator light illuminates on the instrument panel, displaying the message "Battery charging is off, vehicle is at risk of running out of power." This message alerts the user to the risk of running out of power, which could compromise the vehicle's normal operation.

[0128] In another example, when the vehicle's power-saving function is activated, indicating that the vehicle has applied high voltage, the vehicle's drive type is obtained, and the target control strategy for the vehicle is determined based on the vehicle's drive type and the second charge level of the battery.

[0129] Optionally, the vehicle can be either a pure electric drive type or a hybrid drive type. The drive type of the vehicle can be determined based on the actual situation, and no specific limitation is made here.

[0130] For example, when the vehicle's power-saving function is enabled, and the vehicle's drive type is pure electric, the second charge level of the battery is used to determine whether the vehicle's power needs to be turned off.

[0131] When the vehicle's battery protection function is activated, and the vehicle's drive type is hybrid, an inquiry message is output to ask the user whether to activate parking charging, and feedback information is received. If the feedback message indicates that parking charging is activated, the parking charging function in the vehicle is directly activated; if the feedback message indicates that parking charging is deactivated, the system uses the battery's second charge level to determine whether the vehicle's power needs to be turned off (e.g., if the battery's second charge level is less than 70%, the vehicle's power is turned off).

[0132] The above technical solution determines the target control strategy based on the vehicle's drive type and the second battery level. When the vehicle's power-saving function is activated, it indicates that the vehicle has been connected to high voltage. By using the battery's SOC and the vehicle's drive type, the system aims to maximize the vehicle's parking time and thus improve the user experience.

[0133] For example, when the vehicle's power-saving function is enabled, the vehicle's drive type is obtained. If the vehicle's drive type is pure electric and the second battery level is less than the first preset battery level, turning off the vehicle's power is determined as the target control strategy. If the vehicle's drive type is hybrid and the second battery level is less than the second preset battery level, the target control strategy is determined based on the vehicle type of the hybrid drive type.

[0134] Optionally, the first preset battery level can be 65%, 70%, 75%, etc. The first preset battery level can be determined according to the actual situation, and no specific limitation is made here.

[0135] Optionally, the second preset power level can be 45%, 50%, 55%, etc. The second preset power level can be determined according to the actual situation, and no specific limitation is made here.

[0136] It should be noted that the second preset battery level is less than the first preset battery level. For example, the first preset battery level is 70%, and the second preset battery level is 50%. Since pure electric vehicles cannot be charged while parked, the first preset battery level is larger. Hybrid vehicles can be charged while parked, so the second preset battery level is less than the first preset battery level. In other words, the preset battery level is determined according to the vehicle's drive type.

[0137] For example, the second charge level of the battery can be determined by the battery's state of charge (SOC), or it can be determined by the battery voltage. The second charge level of the battery can be determined according to the actual situation, and no specific limitation is made here.

[0138] For example, when the vehicle's power-saving function is activated, it indicates that the low-voltage function is active. When the vehicle's drive type is pure electric, it determines whether the battery's second charge level is less than 70% (the first preset charge level). If the battery's second charge level is greater than or equal to 70%, it continues to monitor the battery's second charge level. When the battery's second charge level is less than 70%, shutting down the vehicle's power is determined as the target control strategy, and a prompt message "Battery charge is low, vehicle power will be shut down soon" is output. After the prompt message is output, the vehicle's power is shut down.

[0139] When the vehicle's drive type is hybrid, determine if the battery's second charge level is less than 50%. If the battery's second charge level is greater than or equal to 50%, continue monitoring the battery's second charge level. When the battery's second charge level is less than 50%, determine the target control strategy based on the vehicle type.

[0140] The above technical solution specifies that when the vehicle's drive type is pure electric and the second battery level is less than the first preset battery level, shutting off the vehicle's power is determined as the target control strategy. When the vehicle's drive type is hybrid and the second battery level is less than the second preset battery level, the target control strategy is determined based on the hybrid drive type of the vehicle. Since parking charging can only be performed on hybrid vehicles, while pure electric vehicles cannot be parked for charging, the second preset battery level is less than the first preset battery level. For pure electric vehicles, when the battery's SOC is low, the vehicle's power needs to be shut off to ensure normal vehicle use. For hybrid vehicles, when the battery's SOC is low, the target control strategy can be further determined based on the vehicle type, thereby achieving intelligent energy saving of the vehicle, improving the user experience while reducing the risk of battery depletion.

[0141] To improve the user experience, a target control strategy can be determined based on the vehicle type to reduce the risk of vehicle battery depletion.

[0142] For example, when the vehicle's drive type is hybrid drive type and the second charge of the battery is less than the second preset charge, the vehicle type is obtained. When the vehicle type is the first preset model, parking charging is determined as the target control strategy. When the vehicle type is the second preset model, the vehicle's historical energy-saving strategy is determined as the target control strategy. When the vehicle type is the third preset model, turning off the vehicle's power is determined as the target control strategy.

[0143] It should be noted that the energy-saving requirements of the first preset model are less than those of the second preset model, and the energy-saving requirements of the second preset model are less than those of the third preset model. For example, the first preset model might be a high-end model, the second preset model a mid-range model, and the third preset model a low-end model. The classification of the first, second, and third preset models can refer to the classification methods used by car manufacturers, and no specific limitations are made here.

[0144] Optionally, the historical energy-saving strategy may be to charge the vehicle while it is parked or to turn off the vehicle's power. The historical energy-saving strategy will be determined based on the actual situation and will not be specifically limited here.

[0145] The above technical solution determines parking charging as the target control strategy when the vehicle type is the first preset model, determines the vehicle's historical energy-saving strategy as the target control strategy when the vehicle type is the second preset model, and determines turning off the vehicle's power as the target control strategy when the vehicle type is the third preset model. As the energy-saving requirements of the vehicle type decrease, the vehicle's energy consumption is reduced, which can improve the user experience.

[0146] S330 controls vehicles based on a target control strategy.

[0147] For example, after determining the target control strategy for the vehicle based on the first charge level of the power battery and the second charge level of the storage battery, controlling the vehicle based on the target control strategy can reduce the risk of the vehicle running out of power.

[0148] For example, based on the determination of the target control strategy, an updated control strategy can also be determined according to the user's configuration information, and the vehicle can be controlled through the updated control strategy.

[0149] The above technical solution, when the vehicle is parked, determines the target control strategy of the vehicle based on the first charge level of the power battery and the second charge level of the storage battery, and controls the vehicle based on the target control strategy. Compared with the prior art that prompts the user to charge the vehicle as soon as possible when the power battery charge is too low, this application determines the target control strategy (energy-saving strategy) that can reduce the vehicle's power consumption based on the first charge level of the power battery and the second charge level of the storage battery. By combining the SOC of the power battery and the SOC of the storage battery, the parking time of the vehicle can be maximized. By reducing the vehicle's power consumption through the target control strategy, the risk of the vehicle running out of power can be reduced while improving the user experience.

[0150] Figure 4 This is a schematic flowchart of another vehicle control method provided in the embodiments of this application.

[0151] For example, Figure 4 The method shown can be executed by the vehicle's body domain controller or chip.

[0152] For example, such as Figure 4 As shown, the vehicle control method 400 includes the following processes:

[0153] S401, when the vehicle is parked and the high-voltage system is powered on.

[0154] For example, the parking status indicates that the vehicle is powered on but not in motion.

[0155] For example, when the vehicle is parked and the high-voltage system is powered on, meaning the vehicle's electrical system and high-voltage power system are activated, the electronic equipment and battery management system are in operation (i.e., the vehicle is in the ON position), the vehicle is not in motion, and the vehicle is in the P position.

[0156] S402, after the T0 timer, determine if there is anyone inside the vehicle; if not, proceed to S403; if yes, proceed to S406.

[0157] For example, when the vehicle is parked and the high-voltage system is powered on, a T0 timer (e.g., 120 seconds, calibrated) is started. After the T0 timer expires, it is determined whether there is anyone in the vehicle. Specifically, after the T0 timer expires, in-vehicle data is collected via an in-vehicle camera, seat sensors, and sleeper berth sensors. The presence of a user in the vehicle is determined based on this data.

[0158] S403, the vehicle is not in OTA mode and all doors are closed.

[0159] For example, when no one is in the car, it checks whether all the car doors are closed (whether all the doors in the vehicle are in the closed state). If all the car doors are closed, it checks whether the vehicle is in OTA (Over-The-Air) status. If the vehicle is not in OTA status, the user may forget to lock the car.

[0160] S404 sends a message to the mobile app stating "Vehicle unlocked".

[0161] For example, when the vehicle is unmanned, not in OTA mode, and all doors are closed, a "vehicle unlocked" lock prompt message is sent to the mobile APP so that the user can lock the car and turn off the power according to the lock prompt message.

[0162] S405, BDM performs power OFF and controls vehicle locking.

[0163] For example, after outputting the "Vehicle unlocked" locking prompt message, a T3 timer (e.g., 60 seconds, calibrable) is started. When the user issues a locking command within the T3 timer, the BDM (Battery Management Device) shuts off its power and locks the vehicle. When the T3 timer expires, the number of prompts is counted once, and the locking prompt message is re-outputted. When the user issues a locking command within the T3 timer, the BDM shuts off its power and locks the vehicle. When the T3 timer expires, it is determined whether the number of prompts is greater than 3 (calibrable). If the number of prompts is greater than 3, the BDM shuts off its power and locks the vehicle. If the number of prompts is less than or equal to 3, the locking prompt message is re-outputted, and subsequent steps are executed.

[0164] S406, SOC1 < 35% and I > -1A; if not, execute S401; if yes, execute S407.

[0165] It should be noted that SOC1 represents the initial charge of the power battery (or the SOC of the power battery). I represents the current of the power battery. When I is greater than -1A, the power battery is in a discharging state. When I is less than or equal to -1A, the power battery is in a charging state.

[0166] For example, when someone is in the vehicle, it is determined whether SOC1 is less than 35% (the third preset charge level) and whether I is greater than -1A, thereby determining an energy-saving strategy based on the SOC of the power battery and its charge / discharge state. When SOC1 is greater than or equal to 35% or I is less than or equal to -1A, the SOC of the power battery continues to be monitored.

[0167] S407, PIU sends "SOC low, please charge in time" to the instrument panel screen, central control screen and mobile APP.

[0168] For example, when SOC1 is less than 35% (the SOC of the power battery is less than the third preset charge) and I is greater than -1A, it is determined that the SOC of the power battery is low and the power battery is in a discharging state. The system sends "SOC is low, please charge in time" to the instrument panel screen, the central control screen and the mobile APP through PIU to remind the user that the vehicle is at risk of running out of power and needs to be charged to reduce the risk of running out of power.

[0169] S408, SOC1 < 30% and I > -1A; if not, execute S401; if yes, execute S409.

[0170] For example, it is determined whether SOC1 is less than 30% (fourth preset charge level) and whether I is greater than -1A, thereby determining an energy-saving strategy based on the SOC of the power battery and the charge / discharge state of the power battery. When SOC1 is greater than or equal to 30% or I is less than or equal to -1A, the SOC of the power battery continues to be monitored.

[0171] S409, PIU sends "SOC low shut down some high voltage functions" to the instrument panel screen, central control screen and mobile APP.

[0172] For example, when SOC1 is less than 30% (the SOC of the power battery is less than the fourth preset charge) and I is greater than -1A, it is determined that the SOC of the power battery is low and the power battery is in a discharging state. The system sends "SOC low, shut down some high-voltage functions" to the instrument panel screen, central control screen and mobile APP through PIU to remind the user that the vehicle is at risk of running out of power and that some high-voltage functions need to be shut down (such as shutting down the power supply of the motor drive system, the power supply of the air conditioning system, the power supply of the steering system and the power supply of the air compressor).

[0173] S410, PIU controls the power supply of the motor drive system, air conditioning system, steering system and air compressor to be turned off, while keeping the DC-DC power supply on.

[0174] For example, after sending "SOC low, shut down some high-voltage functions" to the instrument panel screen, central control screen and mobile APP via PIU, PIU controls the power supply of motor drive system, air conditioning system, steering system and air compressor to shut down, while keeping the DC-DC power supply on.

[0175] S411, SOC1 < 25% and I > -1A; if not, execute S401; if yes, execute S412.

[0176] For example, it is determined whether SOC1 is less than 25% (the fifth preset charge level) and whether I is greater than -1A, thereby determining an energy-saving strategy based on the SOC of the power battery and its charge / discharge state. When SOC1 is greater than or equal to 25% or I is less than or equal to -1A, the SOC of the power battery continues to be monitored.

[0177] S412, PIU sends "SOC low, shut down all high voltage functions" to the instrument panel screen, central control screen and mobile APP.

[0178] For example, when SOC1 is less than 25% (the SOC of the power battery is less than the fifth preset charge) and I is greater than -1A, it is determined that the SOC of the power battery is low and the power battery is in a discharging state. The system sends "SOC low, shut down all high voltage functions" to the instrument panel screen, central control screen and mobile APP through PIU to remind the user that the vehicle is at risk of running out of power and needs to be charged to reduce the risk of running out of power.

[0179] S413, after timer T1, determine if I > -1A; if not, execute S401; if yes, execute S414.

[0180] For example, after sending "SOC low, shut down all high-voltage functions" to the instrument panel screen, central control screen and mobile APP via PIU, the T1 timer (e.g., 20 seconds, which can be calibrated) is started, and after the T1 timer is set (after the T1 timer expires), the current current of the power battery is used to determine whether the power battery is in a discharging state. When the power battery is in a charging state, the SOC of the power battery is continuously monitored.

[0181] S414, PIU controls the vehicle to reduce high voltage and activates the vehicle's power protection function.

[0182] For example, after sending "SOC low, shut down some high voltage functions" to the instrument panel screen, central control screen and mobile APP via PIU, and the T1 timer expires, the vehicle is controlled to reduce high voltage and activate the vehicle power protection function via PIU.

[0183] S415, the charging alarm indicator light on the instrument panel is lit, and a pop-up message says "Battery charging is off, there is a risk of battery depletion".

[0184] For example, the PIU controls the vehicle to reduce high voltage and activate the vehicle's power protection function, controls the vehicle's power protection function to activate (the vehicle's power protection function is activated after the high voltage is reduced), and illuminates the charging alarm indicator on the instrument panel screen, displaying a pop-up message "Battery charging is off, there is a risk of battery drain," so as to inform the user that the vehicle is at risk of battery drain and it is difficult to ensure the normal use of the vehicle in the future.

[0185] S416, determine whether the vehicle is a hybrid vehicle; if yes, proceed to S417; if no, proceed to S421.

[0186] For example, when the vehicle's power-saving function is activated, it indicates that the vehicle has been connected to high voltage, and it is determined whether the vehicle is a hybrid vehicle (determining whether the vehicle's drive type is a hybrid drive model).

[0187] S417, SOC2 < 50% or U < 24.5V; if so, then execute S418.

[0188] It should be noted that SOC2 indicates the second charge level of the battery (or the battery's SOC). U indicates the battery voltage.

[0189] For example, when the vehicle is a hybrid vehicle, it is determined whether the SOC of the battery is less than 50% (second preset charge level) or whether the battery voltage is less than 24.5V (calibrable). When the SOC of the battery is greater than or equal to 50% or the battery voltage is greater than or equal to 24.5V, the SOC of the battery is continuously monitored.

[0190] S418, determine whether to enable parking charging; if yes, proceed to S419; if no, proceed to S424.

[0191] For example, when the battery's SOC is less than 50% or the battery voltage is less than 24.5V, it is determined whether to enable parking charging. Parking charging is off by default, and whether to enable parking charging can be determined through the user's configuration information.

[0192] When the parking charging function is turned off, the BDM will activate the power OFF, and the vehicle will enter a sleep state.

[0193] S419, R > 500Rpm and I ≤ -1A; if yes, then execute S420; otherwise, execute S424.

[0194] It should be noted that R indicates the current engine speed in the vehicle. I indicates the current of the power battery.

[0195] For example, when parking charging is activated in the vehicle, it is determined whether the current engine speed is greater than 500 RPM (calibrable) and whether the current current of the power battery is less than or equal to -1A. If the current engine speed is less than or equal to 500 RPM or the current current of the power battery is greater than -1A, the parking charging function fails to start, so the parking charging function is turned off, the BDM executes power OFF, and the entire vehicle enters a sleep state.

[0196] S420, charging while parked.

[0197] For example, when parking charging is activated in the vehicle, the current engine speed is greater than 500 RPM, and the current current of the power battery indicates that the power battery is in a charging state, the parking charging function is determined to be successfully activated, and parking charging continues to ensure the vehicle's feasibility and improve the user experience.

[0198] S421, SOC2 < 70% or U < 25.1V; if so, then execute S422.

[0199] For example, when the vehicle is a pure electric vehicle, it is determined whether the SOC of the battery is less than 70% (first preset charge) or whether the battery voltage is less than 25.1V (calibrable). When the SOC of the battery is greater than or equal to 70% or the battery voltage is greater than or equal to 25.1V, the SOC of the battery is continuously monitored.

[0200] S422, PIU sends "Battery power is low and power will be shut down soon" to the mobile APP and starts the T2 timer.

[0201] For example, when the battery's SOC is less than 70% or the battery voltage is less than 25.1V, it is determined that the battery's charge is low. The system sends a message "Battery charge is low, power will be shut down soon" to the mobile app via PIU and starts a T2 timer (e.g., 20 seconds, which can be calibrated).

[0202] S423, determine if timer T2 has timed out; if so, execute S424.

[0203] For example, it is determined whether the T2 timer has timed out, and then the vehicle's energy-saving strategy is determined.

[0204] S424, BDM executes power OFF.

[0205] For example, if the T2 timer expires, the parking charging function is turned off, the BDM executes power OFF, and the vehicle enters a sleep state.

[0206] The above technical solution, when a user is present in the vehicle, determines a target control strategy (energy-saving strategy) to reduce the vehicle's energy consumption based on the first charge level of the power battery and the second charge level of the storage battery. By combining the SOC of the power battery and the SOC of the storage battery, the vehicle's parking time can be maximized. Furthermore, as the SOC of the power battery gradually decreases, the strength of the target control strategy (energy-saving strategy) to reduce the vehicle's energy consumption gradually increases, thereby reducing the risk of the vehicle running out of power by controlling the vehicle through the target control strategy.

[0209] Figure 5 This is a schematic diagram of the structure of a vehicle control device provided in an embodiment of this application.

[0210] For example, such as Figure 5 As shown, the vehicle control device 500 includes:

[0211] Acquisition module 510: used to acquire the first charge level of the power battery and the second charge level of the storage battery when the vehicle is in a parked state;
