Description

Technical Field

[0001] The present application relates to the field of vehicles, and more specifically, to a vehicle control method, a device, a vehicle and a storage medium in the field of vehicles. Background Art

[0002] At present, if a vehicle cannot be driven due to a fault, such as a fault in the high-voltage system of the vehicle, which causes the high-voltage system to fail to work properly and thus causes the vehicle to be unable to drive, the vehicle may need to wait for rescue on the roadside. At this time, since the high-voltage system of the vehicle cannot work, the low-voltage system of the vehicle, that is, the 12V battery, needs to be used for power supply.

[0003] However, if the low-voltage system continues to power various loads in the vehicle during the failure of the high-voltage system, the 12V battery may be quickly depleted, causing the 12V battery to be depleted, thereby affecting the rescue of the vehicle. Summary of the invention

[0004] The present application provides a vehicle control method, device, vehicle and storage medium, which can reduce the power consumption of the battery and avoid the battery running out of power due to long-term power consumption while the vehicle is waiting for rescue, thereby affecting the rescue of the vehicle.

[0005] In a first aspect, a vehicle control method is provided, the method comprising: obtaining a current health value and a target power value of a battery of the vehicle when it is determined that a power system of the vehicle cannot enter a high-voltage power-on state; determining a target state of an electrical device inside the vehicle that is powered by the battery based on the current health value and the target power value of the battery; wherein the target state is a state of reducing the power consumption of the battery; and controlling the electrical device to be in the target state until the power system of the vehicle enters the high-voltage power-on state.

[0006] The above technical solution can timely understand the working status of the battery by real-time monitoring the health value and power value of the battery when it is determined that the power system of the vehicle cannot enter the high-voltage power-on state. The target state of the power-consuming equipment is determined based on the current health value and target power value of the battery, and the power-consuming equipment is controlled to be in the target state during the period when the power system of the vehicle cannot enter the high-voltage power-on state, so as to maximize the use of limited battery resources and improve energy utilization. Since the target state includes a state of reducing the power consumption of the battery, by controlling the power-consuming equipment to be in the target state, the power consumption of the battery can be reduced, avoiding the battery from running out of power due to long-term power consumption while the vehicle is waiting for rescue, thereby affecting the rescue of the vehicle.

[0007] In combination with the first aspect, in certain implementations of the first aspect, obtaining the target power value of the battery of the vehicle includes: determining whether a power supply duration for the battery to supply power to the electrical equipment is set; if it is determined that the power supply duration is not set, determining the first power value as the target power value; wherein the first power value is a power value obtained when it is determined that the power system of the vehicle cannot enter a high-voltage power-on state; if it is determined that the power supply duration is set, starting the timing to obtain the timing duration; determining the second power value as the target power value; wherein the second power value is a power value obtained when it is determined that the timing duration is equal to the power supply duration.

[0008] The above technical solution can fully consider the power demand of different users in different scenarios by judging whether to set the power supply time of the battery to the power-consuming equipment. If the power supply time is not set, it means that the use of the power-consuming equipment can be directly restricted, and the first power value obtained when it is determined that the power system of the vehicle cannot enter the high-voltage power-on state can be determined as the target power value; if the power supply time is set, it means that the user may have power demand, and the use of the power-consuming equipment is not restricted temporarily, and the timing can be started to obtain the timing time, and the second power value obtained when the timing time is equal to the power supply time is determined as the target power value. Thus, based on the current health value and the target power value, the target state of the power-consuming equipment is determined, and by controlling the power-consuming equipment to be in the target state, the purpose of reducing the power consumption of the battery is achieved, which helps to prevent the battery from being exhausted and protect the life and performance of the battery. Through timing and control, it can ensure that the power of the battery is reasonably used within the range set by the user, avoiding the failure of the vehicle to start normally or other power system failures due to excessive use of the battery power.

[0009] In combination with the first aspect and the above-mentioned implementation methods, in some implementation methods of the first aspect, before determining the second power value as the target power value, the method also includes: when the current health value is greater than a preset health threshold, obtaining the discharge current of the battery and obtaining the power supply time set by the user; based on the discharge current, the power supply time, the first power value and the battery capacity of the battery, judging whether the battery can meet the power supply demand of the electrical device within the power supply time; if it is determined that the battery cannot meet the power supply demand of the electrical device within the power supply time, determining the first power value as the target power value; determining the second power value as the target power value includes: if it is determined that the battery can meet the power supply demand of the electrical device within the power supply time, determining the second power value as the target power value.

[0010] In the above technical solution, before determining the second power value as the target power value, it is first determined whether the battery can meet the power supply demand of the power-consuming equipment within the power supply time. If it is determined that the battery cannot meet the power supply demand of the power-consuming equipment within the power supply time, the first power value obtained when the vehicle's power system cannot enter the high-voltage power-on state is directly determined as the target power value, thereby determining the target state of the power-consuming equipment based on the current health value of the battery and the target power value, and achieving the purpose of reducing the power consumption of the battery by controlling the power-consuming equipment to be in the target state. If it is determined that the power supply demand of the power-consuming equipment can be met, the second power value is determined as the target power value, which can further prevent the battery from being exhausted while fully considering the power demand of different users in different scenarios, and avoid battery depletion due to long-term power consumption of the battery while the vehicle is waiting for rescue, thereby affecting the rescue of the vehicle.

[0011] In combination with the first aspect and the above-mentioned implementation methods, in some implementation methods of the first aspect, the determination of whether the battery can meet the power supply demand of the electrical equipment within the power supply time is based on the discharge current, the power supply time, the first power value and the battery capacity of the battery, including: calculating the product of the power supply time and the discharge current, calculating the ratio between the product and the battery capacity of the battery, and calculating the difference between the first power value and the ratio; determining whether the absolute value of the difference is greater than or equal to a preset difference; if the absolute value of the difference is greater than or equal to the preset difference, determining that the battery can meet the power supply demand of the electrical equipment within the power supply time; if the absolute value of the difference is less than the preset difference, determining that the battery cannot meet the power supply demand of the electrical equipment within the power supply time.

[0012] In combination with the first aspect and the above-mentioned implementation methods, in some implementation methods of the first aspect, when it is determined that the battery cannot meet the power supply demand of the electrical equipment within the power supply time, the method also includes: controlling the discharge current of the battery to decrease until the battery can meet the power supply demand of the electrical equipment within the power supply time.

[0013] The above technical solution can control the discharge current of the battery to decrease when it is determined that the battery cannot meet the power supply demand of the electrical equipment within the power supply time, thereby further reducing the power consumption of the battery.

[0014] In combination with the first aspect and the above-mentioned implementation methods, in some implementation methods of the first aspect, the target state of the electrical equipment powered by the battery inside the vehicle is determined based on the current health value and the target power value of the battery, including: when the current health value is less than or equal to the preset health threshold, the target state of the electrical equipment is determined to be the off state; when the current health value is greater than the preset health threshold, if the target power value is greater than the first preset power threshold, the target state of the electrical equipment is determined to be the first energy-saving state; if the target power value is less than or equal to the first preset power threshold and greater than the second preset power threshold, the target state of the electrical equipment is determined to be the second energy-saving state; wherein the first preset power threshold is greater than the second preset power threshold; the energy-saving degree of the second energy-saving state is higher than the energy-saving degree of the first energy-saving state; if the target power value is less than or equal to the second preset power threshold, the target state of the electrical equipment is determined to be the off state.

[0015] The above technical solution determines the different states of the electrical equipment according to the current health value and the target power value, and the energy-saving degree of the different states of the electrical equipment is also different, which can realize refined energy management and minimize the power consumption of the battery to the greatest extent while ensuring the user experience.

[0031] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0032] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying 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 the features.

[0033] At present, if a vehicle cannot be driven due to a fault, such as a fault in the high-voltage system of the vehicle, which causes the high-voltage system to fail to work properly and thus causes the vehicle to be unable to drive, the vehicle may need to wait for rescue on the roadside. At this time, since the high-voltage system of the vehicle cannot work, the low-voltage system of the vehicle, that is, the 12V battery, needs to be used for power supply.

[0034] However, if the low-voltage system continues to power various loads in the vehicle during the failure of the high-voltage system, the 12V battery may be quickly depleted, causing the 12V battery to be depleted, thereby affecting the rescue of the vehicle.

[0035] Specifically, a low 12V battery may prevent the vehicle from starting and making it difficult to move to a safe location or repair station. If the vehicle is parked in an unsafe location (such as the center of a lane) and cannot be started or use the warning lights, it may cause a traffic accident and affect the safety of the vehicle. A low 12V battery may also make the vehicle's onboard communication equipment unusable, and it may be impossible to contact the outside world in a timely manner and accurately report the vehicle's location to rescuers. In addition, the rescue vehicle may not be able to start the faulty vehicle by jump-charging, because the low-power battery cannot be charged by an external power source. This will greatly increase the difficulty and time cost of rescue, and may even prevent the rescue from proceeding smoothly.

[0036] In order to solve the above technical problems, an embodiment of the present application provides a vehicle control method, and the executor of the method is a vehicle, specifically a controller in the vehicle.

[0037] Figure 1 It is a schematic diagram of a vehicle control system provided in an embodiment of the present application.

[0038] For example, Figure 1 As shown, the vehicle control system 100 includes a battery 101, an electrical battery sensor (EBS) 102, a central electronic module (CEM) 103, a lighting system controller 104, a waiting rescue mode switch 105, an audio and video entertainment system controller 106 and a power system controller 107.

[0039] The battery 101 can supply power to the EBS 102, the CEM 103 and other vehicle loads. For example, the battery can be a low-voltage battery such as a lead-acid battery or a lithium battery. The embodiment of the present application does not limit the type of the battery.

[0040] The EBS 102 is used to detect the status of the battery, including the battery power value and health value; and is also used to send the battery status to the CEM 103 .

[0041] Exemplarily, if the battery is a lead-acid battery, the state of the lead-acid battery is detected by the EBS; if the battery is a lithium battery, the state of the lithium battery is detected by the battery management system (BMS).

[0042] CEM 103 is used to receive the battery status signal sent by EBS 102, and is also used to receive the status signal of the waiting rescue mode switch 105. CEM 103 can also perform calculations based on the received signals, formulate reminder logic, and send instructions or signals to other systems.

[0043] The lighting system controller 104 is used to control the on or off of the lights inside and outside the vehicle.

[0044] The waiting rescue mode switch 105 is used to control the on or off state of the "waiting rescue mode" in the vehicle. The waiting rescue mode switch 105 can be integrated in the vehicle multimedia host (Head Unit, HUT). Among them, the waiting rescue mode can be understood as a mode that is turned on after the vehicle encounters a breakdown or accident in order to ensure the safety of the occupants and facilitate the arrival of rescue personnel at the scene. After the waiting rescue mode is turned on, the emergency lights (i.e., "double flash lights") on the outside of the vehicle are turned on, waiting for rescue.

[0045] The audio-visual entertainment system controller 106 is used to control the opening or closing of the display system, audio system and other audio-visual entertainment devices in the vehicle.

[0046] The powertrain controller 107 is used to monitor and control the operation of the engine and other powertrain systems in the vehicle.

[0047] For example, if CEM 103 receives a status signal indicating that the waiting rescue mode switch 105 is in the on state and determines that the vehicle has entered the waiting rescue mode, it means that the vehicle may be unable to drive due to a malfunction or accident and needs rescue. Then, according to the status signal of the battery 101 sent by EBS 102, a reminder and control logic can be formulated, and instructions or signals can be sent to other systems, such as sending instructions or signals to the lighting system controller 104, the audio and video entertainment system controller 106 and the power system controller 107, so as to limit the use of electrical appliances in the vehicle.

[0048] In the above system, when the CEM determines that the vehicle has entered the waiting for rescue mode, it can determine the control logic of the electrical equipment powered by the battery in the vehicle based on the battery power value and health value, and send instructions or signals to the corresponding controller. It can limit the power consumption of various electrical appliances in the vehicle while the vehicle is waiting for rescue, and avoid the battery being depleted due to long-term and large power consumption while the vehicle is waiting for rescue, thereby affecting the rescue of the vehicle.

[0049] Figure 2 It is a schematic flow chart of a vehicle control method provided in an embodiment of the present application.

[0050] For example, Figure 2 As shown, the method 200 includes:

[0051] S201, when it is determined that the power system of the vehicle cannot enter the high-voltage power-on state, obtain the current health value and target power value of the battery of the vehicle.

[0052] S202, determining a target state of electrical devices in the vehicle that are powered by the battery based on the current health value and the target power value of the battery.

[0053] The target state is a state in which the power consumption of the battery is reduced.

[0054] S203, controlling the electrical equipment to be in a target state until the power system of the vehicle enters a high-voltage power-on state.

[0055] In an embodiment of the present application, when it is determined that the power system of the vehicle cannot enter the high-voltage power-on state, the working state of the battery can be timely understood by real-time monitoring of the health value and power value of the battery. The target state of the power-consuming equipment is determined based on the current health value and target power value of the battery, and the power-consuming equipment is controlled to be in the target state during the period when the power system of the vehicle cannot enter the high-voltage power-on state, so as to maximize the use of limited battery resources and improve energy utilization. Since the target state includes a state of reducing the power consumption of the battery, by controlling the power-consuming equipment to be in the target state, the power consumption of the battery can be reduced, and the battery power loss due to long-term power consumption of the battery while the vehicle is waiting for rescue can be avoided, thereby affecting the rescue of the vehicle.

[0056] Below Figure 2 The specific implementation of each step in the embodiment shown is described as follows:

[0057] Regarding the above S201, it can be understood that the above high-voltage power-on state refers to a state in which the high-voltage battery system of the vehicle is ready to supply power to the motor and other high-voltage devices.

[0058] Normally, when the power system of a vehicle enters a high-voltage power-on state, it is considered that the power system can operate normally and that the power system can provide sufficient power for the vehicle to drive the vehicle.

[0059] If the power system cannot enter the high-voltage power-on state, it may be that the high-voltage battery has a fault and cannot supply power normally, or the vehicle may detect that there is a safety hazard in the high-voltage system and automatically cut off the high-voltage voltage. In short, if the power system cannot enter the high-voltage power-on state, the vehicle cannot drive normally.

[0060] In some embodiments, when the vehicle is unable to drive normally, the user can turn on the wait for rescue mode in the vehicle's HUT.

[0061] For example, the user can turn on the waiting rescue mode through the control switch of the "waiting rescue mode" integrated in the HUT, and can also initiate a voice command "turn on waiting rescue mode" to turn on the waiting rescue mode. The embodiment of the present application does not limit the way to turn on the waiting rescue mode.

[0062] Furthermore, when it is determined that the vehicle's wait-for-rescue mode is on, the emergency lights on the outside of the vehicle (i.e., "double flash lights") can be controlled to remain on, and distress information, including the vehicle's location, fault conditions, etc., can be sent to emergency contacts or rescue platforms through the on-board communication system, such as on-board Bluetooth, wireless networks, etc.

[0063] As mentioned above, the current health value and target power value of the above-mentioned battery can be obtained through the battery sensor.

[0064] The current state of health (SOH) of a battery is an indicator used to measure the performance level of a battery relative to its new state. The health value is usually expressed as a percentage, and the lower the value, the worse the battery performance.

[0065] The battery's State of Charge (SOC) is an indicator used to measure the ratio of the battery's current charge to its maximum battery capacity. The charge value is usually expressed as a percentage, and the higher the value, the more sufficient the battery's charge is.

[0066] Furthermore, since the health value of the battery reflects its performance level relative to the new state of the battery. When the health value is lower than a certain threshold, it means that the overall performance of the battery has significantly declined and may not be able to provide stable power support. Therefore, it is necessary to first confirm whether the battery is still in a good health state, that is, first obtain the current health value of the battery and determine whether the current health value is greater than the preset health threshold.

[0067] For example, the preset health threshold can be set according to actual needs, for example, it can be set to 70%. If the current health value of the battery is greater than 70%, it means that the battery is in a healthy state; if the current health value of the battery is less than or equal to 70%, it means that the battery is in an unhealthy state.

[0068] When it is determined that the current health value is greater than the preset health threshold, it indicates that the battery is in a healthy state. The power value of the battery can be further obtained, and based on the first power value of the battery, the target state of the electrical device can be determined.

[0069] As mentioned above, during the failure of the high-voltage system, the low-voltage system continues to supply power to various loads in the vehicle, and the power is mainly supplied by the battery in the low-voltage system. The battery in the vehicle is usually only 12V. If the battery is powered for a long time and cannot be charged, the battery may be exhausted, resulting in battery power loss. Based on this, when it is determined that the vehicle's power system cannot enter the high-voltage power-on state, the current state of the battery can be accurately known by obtaining the current health value and target power value of the battery.

[0070] Furthermore, the actual needs of the user can be obtained, and the energy-saving strategy of the battery can be determined based on the actual needs and the current state of the battery.

[0071] In one possible implementation, obtaining the target power value of the battery of the vehicle includes: determining whether a power supply duration of the battery to the electrical equipment is set; if it is determined that the power supply duration is not set, determining a first power value as the target power value; wherein the first power value is a power value obtained when it is determined that the power system of the vehicle cannot enter a high-voltage power-on state.

[0072] It is understood that the above-mentioned electrical equipment refers to equipment powered by batteries inside the vehicle. The above-mentioned electrical equipment powered by batteries inside the vehicle may include but is not limited to instruments, screens, audio, air conditioners, seats, and lights inside and outside the vehicle (excluding emergency lights outside the vehicle).

[0073] The actual needs of the user can be determined by judging whether the power supply time of the battery to the electrical equipment is set. For example, if the user still needs to use the electrical equipment, the power supply time of the battery to the electrical equipment can be set.

[0074] In some embodiments, after the vehicle enters the waiting rescue mode, the options of "entering the energy-saving state immediately" or "entering the energy-saving state later" may be displayed on the HUT screen for the user to select. The controller may determine whether the power supply time of the battery to the electrical equipment is set according to the user's selection operation.

[0075] Exemplarily, if it is detected that the option corresponding to the user's selected operation instruction is "enter energy-saving state immediately", it is determined that the power supply duration is not set; if it is detected that the option corresponding to the user's selected operation instruction is "enter energy-saving state later", it is determined that the power supply duration is set.

[0076] Furthermore, if it is detected that the option corresponding to the user's selected operation instruction is "enter energy-saving state later", the setting option of "power supply duration for electrical equipment" can be displayed on the HUT screen, and "rescuers are expected to arrive in XX minutes" can also be displayed.

[0077] It is understandable that the above power supply duration can be set according to the estimated waiting time for rescue displayed on the screen. During the power supply duration, the user will not be restricted from using battery-powered electrical equipment.

[0078] Exemplarily, the power supply time can be set by the user according to the estimated waiting time for rescue displayed on the screen. For example, if the screen displays "rescuers are expected to arrive in 10 minutes", the user can set the waiting time to 10 minutes on the HUT, that is, there is a set power supply time and the power supply time is 10 minutes.

[0079] If the user does not set it within 10 seconds, the vehicle's controller will set it according to the estimated waiting time for rescue displayed on the screen. For example, if the screen displays "rescuers are expected to arrive in 10 minutes", the waiting time will be set to 10 minutes, that is, there is a set power supply time and the power supply time is 10 minutes.

[0080] Furthermore, if as mentioned above, when it is determined that the power supply time has not been set, it means that the user has selected the option of "entering energy-saving state immediately", and the first power value obtained when the vehicle's power system is unable to enter the high-voltage power-on state can be determined as the target power value, thereby determining the target state of the electrical equipment based on the current health value of the battery and the target power value, and achieving the purpose of reducing the power consumption of the battery by controlling the electrical equipment to be in the target state.

[0081] If it is determined that there is a set power supply duration, it means that the user has selected the option of "entering the energy-saving state later". In this case, there is no need to directly control the power-consuming equipment to enter the energy-saving state. When the battery power supply duration reaches the set power supply duration, the power-consuming equipment will be controlled to enter the energy-saving state. That is, the power value obtained when the timing duration reaches the power supply duration will be determined as the target power value.

[0082] In one possible implementation, the target power value of the battery of the vehicle is obtained, including: if it is determined that a power supply duration is set, starting timing to obtain the timing duration; determining a second power value as the target power value; wherein the second power value is the power value obtained when it is determined that the timing duration is equal to the power supply duration.

[0083] It is understandable that if there is a set power supply duration for the battery to supply power to the electric device, the time is counted from the current time when the power supply duration is set to obtain the time duration. And if the time duration is less than the set power supply duration, the use state of the electric device is not restricted, that is, "enter the energy-saving state later" is executed.

[0084] When the timing duration is equal to the set power supply duration, the second power value after the battery is powered can be obtained, and the second power value can be determined as the target power value. Therefore, based on the current health value and the target power value, the target state of the electrical equipment is determined. By controlling the electrical equipment to be in the target state, the purpose of reducing the power consumption of the battery is achieved.

[0085] Furthermore, as mentioned above, the battery capacity of the battery is usually relatively small. If the power supply duration set by the user is relatively long, the battery may be exhausted for a long time to power the power-consuming device, thereby causing the battery to be depleted. Based on this, it is possible to first determine whether the battery can meet the power supply requirements of the power supply device within the power supply duration, and then determine whether to execute "enter the energy-saving state later".

[0086] In one possible implementation, before the second power value is determined as the target power value, the method also includes: when the current health value is greater than a preset health threshold, obtaining the discharge current of the battery and obtaining the power supply time set by the user; based on the discharge current, the power supply time, the first power value and the battery capacity of the battery, determining whether the battery can meet the power supply demand of the electrical equipment within the power supply time.

[0087] It can be understood that, as mentioned above, when the current health value of the battery is greater than the preset health threshold, it means that the battery is in a healthy state. The discharge current of the battery and the power supply time set by the user can be further obtained to determine whether the battery can meet the power supply needs of the electrical equipment within the power supply time.

[0088] The first power value is a power value obtained when it is determined that the power system of the vehicle cannot enter the power-on state.

[0089] The discharge current of the above-mentioned storage battery can be obtained by a current sensor. The battery capacity of the above-mentioned storage battery is the maximum storage capacity of the storage battery, which is usually a calibrated value.

[0090] In one possible implementation, based on the discharge current, the power supply time, the first power value and the battery capacity of the battery, it is determined whether the battery can meet the power supply demand of the electrical equipment within the power supply time, including: calculating the product of the power supply time and the discharge current, calculating the ratio between the product and the battery capacity of the battery, and calculating the difference between the first power value and the ratio; determining whether the absolute value of the difference is greater than or equal to a preset difference; if the absolute value of the difference is greater than or equal to the preset difference, determining that the battery can meet the power supply demand of the electrical equipment within the power supply time; if the absolute value of the difference is less than the preset difference, determining that the battery cannot meet the power supply demand of the electrical equipment within the power supply time.

[0091] It can be understood that calculating the product of the power supply duration and the discharge current can be understood as calculating the total discharge amount of the battery during the power supply duration, that is, total discharge amount = discharge current * power supply duration.

[0092] Calculating the ratio of the product to the battery capacity of the battery can be understood as calculating the discharge ratio of the battery during the power supply time, that is, discharge ratio = total discharge / battery capacity.

[0093] The difference between the first power value and the ratio (ie, the discharge capacity ratio) is calculated to determine whether the battery can meet the power supply demand of the power-consuming device within the power supply time. ie, the difference = the first power value - the discharge capacity ratio.

[0094] If the absolute value of the difference is greater than or equal to the preset difference, it means that the first power value is much greater than the discharge ratio within the power supply time, that is, the current power of the battery is relatively sufficient. After the discharge ratio of the battery within the power supply time reaches the discharge ratio calculated above, there will still be some power remaining, and the power of the battery will not be exhausted. It is determined that the battery can meet the power supply needs of the electrical equipment within the power supply time.

[0095] If the absolute value of the difference is less than the preset difference, it means that the battery may be exhausted after the discharge amount of the battery within the power supply time reaches the calculated discharge amount ratio, and it is determined that the battery cannot meet the power supply demand of the power-consuming equipment within the power supply time.

[0096] Furthermore, the preset difference can be set according to actual needs, for example, to 40%.

[0097] For example, if the power supply duration is 1 hour (h), the discharge current is 3 amperes (A), and the battery capacity is 30 ampere hours (Ah), the total discharge amount of the battery during the power supply duration is calculated to be 1h*3A=3Ah. The ratio between the total discharge amount and the battery capacity is calculated to be 3Ah / 30Ah=10%.

[0098] If the first power value is 80%, the preset difference is 40%, and the difference between the first power value and the above ratio is calculated to be 80%-10%=70%. The absolute value of 70% is greater than the preset difference of 40%, which means that the battery can meet the power supply needs of the electrical equipment within the power supply time.

[0099] It is understandable that if the battery can meet the power supply needs of electrical equipment within the power supply time, it means that the battery power is relatively sufficient. When the above-mentioned timing time has not reached the power supply time, there is no restriction on the electrical equipment in the vehicle, that is, "enter the energy-saving state later" is executed.

[0100] In a possible implementation, determining the second power value as the target power value includes: if it is determined that the storage battery can meet the power supply demand of the power-consuming device within the power supply duration, determining the second power value as the target power value.

[0101] It is understandable that, as mentioned above, if the battery can meet the power supply needs of the electrical equipment within the power supply time, it means that the current power of the battery is relatively sufficient, and even if the discharge ratio reaches the above-calculated discharge ratio within the power supply time, the battery still has relatively sufficient power. Based on this, if the timing time does not reach the power supply time, the electrical equipment in the vehicle will not be restricted, that is, "enter the energy-saving state later" can be executed.

[0102] When the timing duration is equal to the power supply duration, the second power value after the battery is powered can be obtained, and the second power value can be determined as the target power value. Therefore, based on the current health value and the target power value, the target state of the electrical equipment can be determined. By controlling the electrical equipment to be in the target state, the purpose of reducing the power consumption of the battery can be achieved.

[0103] The above method can fully consider the power consumption needs of different users in different scenarios by judging whether to set the power supply time of the battery to power the electrical equipment. When the timing time is less than the set power supply time, there is no restriction on the use of the electrical equipment, which improves the convenience and comfort of the user in using the electrical equipment. When the timing time reaches the set power supply time, the second power value after the battery is powered is obtained, and the second power value is determined as the target power value, so that the target state of the electrical equipment is determined based on the current health value and the target power value. By controlling the electrical equipment to be in the target state, the purpose of reducing the power consumption of the battery is achieved, which helps to prevent the battery from being exhausted and protect the life and performance of the battery. Through timing and control, it can ensure that the battery power is reasonably used within the range set by the user, avoiding the vehicle from failing to start normally or other power system failures due to excessive use of the battery power.

[0104] Furthermore, if it is determined that the battery cannot meet the power supply demand of the electrical equipment within the power supply time, it means that the power of the battery is not sufficient, and the electrical equipment in the vehicle needs to be restricted immediately.

[0105] In a possible implementation, if it is determined that the storage battery cannot meet the power supply demand of the electrical device within the power supply duration, the first power value is determined as the target power value.

[0106] It can be understood that if it is determined that the battery cannot meet the power supply demand of the electrical equipment within the power supply time, it means that the electrical equipment needs to be restricted immediately. Even if the power supply time is set, the time will no longer be counted. Instead, the first power value obtained when the vehicle's power system cannot enter the high-voltage power-on state is directly determined as the target power value. Based on the current health value of the battery and the target power value, the target state of the electrical equipment is determined. By controlling the electrical equipment to be in the target state, the purpose of reducing the battery's power consumption is achieved.

[0107] For example, if the power supply duration is 2 hours (h), the discharge current is 6 amperes (A), and the battery capacity is 30 ampere hours (Ah), the total discharge amount of the battery during the power supply duration is calculated to be 2h*6A=12Ah. The ratio between the total discharge amount and the battery capacity is calculated to be 12Ah / 30Ah=40%.

[0108] If the first power value is 70%, the preset difference is 40%, and the difference between the first power value and the above ratio is calculated to be 70%-40%=30%. The absolute value of 30% is less than the preset difference of 40%, which means that the battery cannot meet the power supply demand of the electrical equipment within the power supply time.

[0109] In some embodiments, if it is determined that the battery cannot meet the power supply demand of the power-consuming device within the power supply time, a prompt message "The current power of the battery is insufficient to support XX minutes of power supply" may be displayed on the HUT screen.

[0110] The options of "changing the waiting time" and "entering the energy saving state immediately" can also be displayed for the user to choose.

[0111] If the user selects the option of "Change waiting time", the page for changing the waiting time will be displayed. If the user changes the waiting time and the battery can meet the power supply demand of the power-consuming device within the changed waiting time, the timing can be started, and when the timing time is equal to the changed waiting time, the power-consuming device can be restricted.

[0112] If the user changes the waiting time and determines that the battery still cannot meet the power supply demand of the power-consuming equipment within the changed waiting time, the prompt message "The current battery power is insufficient to support XX minutes of power supply" will be displayed again.

[0113] If the user selects the option of "entering energy-saving state immediately", the power-consuming equipment will be restricted immediately.

[0114] The above method determines how to limit the power-consuming equipment by judging whether the battery can meet the power supply demand of the power-consuming equipment within the power supply time. While fully considering the power demand of different users in different scenarios, it can also further prevent the battery from being exhausted, avoiding the battery from being depleted due to long-term power consumption while the vehicle is waiting for rescue, thereby affecting the rescue of the vehicle.

[0115] Furthermore, if it is determined that the battery cannot meet the power supply needs of the electrical equipment within the power supply time, in order to prevent the battery from being exhausted, in addition to immediately determining the target state of the electrical equipment based on the current health value and the first power value of the battery, the discharge current of the battery can also be limited.

[0116] In one possible implementation, when it is determined that the battery cannot meet the power supply demand of the electrical device within the power supply duration, the method also includes: controlling the discharge current of the battery to decrease until the battery can meet the power supply demand of the electrical device within the power supply duration.

[0117] It can be understood that the above-mentioned discharge current refers to the current when the battery supplies power to the electrical equipment.

[0118] The above-mentioned control of reducing the discharge current of the battery can be achieved by a current limiting device in the circuit, such as a current limiter.

[0119] For example, as mentioned above, if the power supply duration is 2 hours (h), the discharge current is 6 amperes (A), and the battery capacity is 30 ampere hours (Ah), the total discharge amount of the battery during the power supply duration is calculated to be 2h*6A=12Ah. The ratio between the total discharge amount and the battery capacity is calculated to be 12Ah / 30Ah=40%.

[0120] If the first power value is 70%, the preset difference is 40%, and the difference between the first power value and the above ratio is calculated to be 70%-40%=30%. The absolute value of 30% is less than the preset difference of 40%, which means that the battery cannot meet the power supply demand of the electrical equipment within the power supply time.

[0121] Furthermore, based on the first power value of 70% and the current health value of 90%, the target state of the power-consuming device is determined to be the second energy-saving state, and the power-consuming device is controlled to be in the second energy-saving state. Then, the discharge current of the battery is controlled to decrease. If the discharge current is reduced to 5A, the battery can meet the power supply demand of the power-consuming device within the power supply time, and the discharge current can be maintained at 5A.

[0122] As mentioned above, if it is determined that the power supply time is not set or it is determined that the battery cannot meet the power supply needs of the electrical equipment within the power supply time, the first power value obtained when the vehicle's power system cannot enter the high-voltage power-on state is directly determined as the target power value; if it is determined that the power supply time is set and it is determined that the battery can meet the power supply needs of the electrical equipment within the power supply time, the second power value obtained when the timing time is equal to the power supply time is determined as the target power value.

[0123] For the above S202 and S203, it can be understood that the above target power value can be the first power value obtained when the vehicle's power system cannot enter the high-voltage power-on state, or it can be the second power value obtained when the timing duration is equal to the power supply duration.

[0124] The battery-powered electrical equipment inside the above-mentioned vehicle may include, but is not limited to, instruments, screens, audio, air conditioning, seats, and interior and exterior lights (excluding emergency lights outside the vehicle).

[0125] In order to more reasonably restrict the electric device, the target state of the electric device can be determined based on the current health value and the target power value of the battery.

[0126] In one possible implementation, the target state of the electrical equipment powered by the battery inside the vehicle is determined based on the current health value and the target power value of the battery, including: when the current health value is less than or equal to the preset health threshold, determining the target state of the electrical equipment to be the off state.

[0127] It is understandable that, as mentioned above, if the current health value of the battery is less than or equal to the preset health threshold, it means that the battery is in an unhealthy state.

[0128] Furthermore, if the battery is in an unhealthy state, if you continue to use electrical equipment, the battery's power will be further consumed, which will accelerate the damage of the battery. In addition, when the battery is in an unhealthy state, the power it provides may be extremely unstable. If you continue to use electrical equipment, the battery's power may be exhausted faster, resulting in battery power loss.

[0129] Based on this, when the current health value is less than or equal to the preset health threshold, the battery-powered electrical equipment in the vehicle can be controlled to be turned off, that is, the target state of the electrical equipment is determined to be the off state.

[0130] In another possible implementation, the target state of the electrical equipment powered by the battery inside the vehicle is determined based on the current health value and the target power value of the battery, including: when the current health value is greater than the preset health threshold, if the target power value is greater than the first preset power threshold, the target state of the electrical equipment is determined to be a first energy-saving state; if the target power value is less than or equal to the first preset power threshold and greater than the second preset power threshold, the target state of the electrical equipment is determined to be a second energy-saving state; wherein the first preset power threshold is greater than the second preset power threshold; the energy-saving degree of the second energy-saving state is higher than the energy-saving degree of the first energy-saving state; if the target power value is less than or equal to the second preset power threshold, the target state of the electrical equipment is determined to be an off state.

[0131] It can be understood that, as described above, when it is determined that the current health value is less than or equal to the preset health threshold, it means that the battery is in a healthy state, and the target state of the electrical equipment can be further determined based on the current power value of the battery.

[0132] Exemplarily, the first preset power threshold and the second preset power threshold can be set according to the actual situation of the vehicle, for example, the first preset power threshold is set to 80%, and the second preset power threshold is set to 40%.

[0133] The first energy-saving state may be set according to a first preset power threshold; the second energy-saving state may be set according to a second preset power threshold.

[0134] If the target power value is greater than the first preset power threshold, it means that the current power of the battery is sufficient to maintain the operation of the vehicle's audio and video entertainment system, but the vehicle's functions need to be restricted. If only the vehicle's functions are restricted, the first energy-saving state can be set to: the air conditioner is in a state of limiting the air volume to no more than 3 gears, the ventilation and heating functions of the seats are turned off, the screen and instrument are in a state of limiting the brightness to no more than 50%, the audio is in a state of limiting the volume to no more than 50%, and the lights inside and outside the car remain in their original state.

[0135] If the target power value is less than or equal to the first preset power threshold and greater than the second preset power threshold, it means that the current power of the battery is sufficient to maintain the operation of the vehicle's audio and video entertainment system, but the vehicle's functions need to be further restricted (more than the first energy-saving state). The second energy-saving state can be set to: the air conditioner is turned off, the ventilation and heating functions of the seats are turned off, the screen and instrument are in a state where the brightness is limited to no more than 50%, the audio is in a state where the volume is limited to no more than 50%, the lights inside the car are turned off, and the lights outside the car remain in their original state.

[0136] If the target power value is less than or equal to the second preset power threshold, it means that the current power of the battery is insufficient to provide entertainment services for the vehicle, and the target state of the electrical device is determined to be the off state.

[0137] Furthermore, after the target state of the electrical device is determined, the electrical device may be controlled to be in the target state.

[0138] Exemplarily, if the target state of the electrical equipment is determined to be the first energy-saving state, the air conditioner is controlled to have an air volume not exceeding level 3, the ventilation and heating functions of the seats are controlled to be turned off, the screen and instrument are controlled to have a brightness not exceeding 50%, the audio system is controlled to have a volume not exceeding 50%, and the lights inside and outside the vehicle are controlled to remain in their original state.

[0139] In some embodiments, after the power-consuming device is controlled to be in the target state, the CEM may start timing and send a high-voltage power-on request to the power system at a preset interval. If the power system enters the high-voltage power-on state after receiving the high-voltage power-on request, the power-consuming device is controlled to be restored to the initial state; if the power system still cannot enter the high-voltage power-on state after receiving the high-voltage power-on request, the power-consuming device is controlled to continue to be in the target state.

[0140] It can be understood that the above initial state refers to the state of the electrical device before the electrical device is controlled to be in the target state.

[0141] The above preset time length can be set according to actual needs, for example, the preset time length can be set to 2 seconds.

[0142] For example, if the preset time length is 2 seconds, after the electrical equipment is controlled to be in the target state, the CEM starts timing and sends a high-voltage power-on request to the power system every 2 seconds. If the power system enters the high-voltage power-on state after receiving the high-voltage power-on request, the electrical equipment is controlled to be restored to the initial state.

[0143] In order to ensure the safety of the vehicle while waiting for rescue, there may be no restrictions on the emergency lights on the outside of the vehicle.

[0144] In a possible implementation, after controlling the electrical device to be in the target state, the method further includes: controlling the emergency lights outside the vehicle to remain in an on state.

[0145] It is understandable that the above-mentioned emergency lights refer to the hazard warning lights at the rear of the vehicle, namely the "double flash".

[0146] When a vehicle cannot enter the high-voltage power-on state, it is usually unable to move. In order to ensure the safety of the vehicle and avoid rear-end collisions, the emergency lights on the outside of the vehicle can be controlled to remain on at all times to alert other road users to the status of the vehicle.

[0147] Figure 3 It is a structural schematic diagram of a vehicle control device provided in an embodiment of the present application.

[0148] For example, Figure 3 As shown, the device 300 includes:

[0149] The acquisition module 301 is used to acquire the current health value and target power value of the battery of the vehicle when it is determined that the power system of the vehicle cannot enter the high-voltage power-on state.

[0150] The determination module 302 is used to determine the target state of the electrical equipment in the vehicle that is powered by the battery based on the current health value and the target power value of the battery.

[0151] The target state is a state of reducing power consumption of the battery.

[0152] The control module 303 is used to control the electrical equipment to be in the target state until the power system of the vehicle enters the high-voltage power-on state.

[0153] In one possible implementation, the acquisition module is specifically used to: determine whether a power supply duration of the battery for supplying power to the electrical equipment is set; if it is determined that the power supply duration is not set, determine the first power value as the target power value; wherein the first power value is the power value obtained when it is determined that the power system of the vehicle cannot enter the high-voltage power-on state; if it is determined that the power supply duration is set, start timing to obtain the timing duration; determine the second power value as the target power value; wherein the second power value is the power value obtained when it is determined that the timing duration is equal to the power supply duration.

[0154] Optionally, the device also includes a judgment module, which is specifically used to: when the current health value is greater than a preset health threshold, obtain the discharge current of the battery and obtain the power supply time set by the user; based on the discharge current, the power supply time, the first power value and the battery capacity of the battery, judge whether the battery can meet the power supply demand of the electrical equipment within the power supply time; if it is determined that the battery cannot meet the power supply demand of the electrical equipment within the power supply time, determine the first power value as the target power value; the acquisition module includes a first determination unit, which is specifically used to: if it is determined that the battery can meet the power supply demand of the electrical equipment within the power supply time, determine the second power value as the target power value.

[0155] In one possible implementation, the judgment module includes a judgment unit, which is specifically used to: calculate the product of the power supply time and the discharge current, calculate the ratio between the product and the battery capacity of the battery, and calculate the difference between the first power value and the ratio; judge whether the absolute value of the difference is greater than or equal to a preset difference; if the absolute value of the difference is greater than or equal to the preset difference, determine that the battery can meet the power supply demand of the electrical device within the power supply time; if the absolute value of the difference is less than the preset difference, determine that the battery cannot meet the power supply demand of the electrical device within the power supply time.

[0156] In a possible implementation, the judgment module further includes a control unit, which is specifically used to control the discharge current of the battery to decrease until the battery can meet the power supply demand of the electrical device within the power supply time.

[0157] In one possible implementation, the determination module is specifically used to: when the current health value is less than or equal to a preset health threshold, determine that the target state of the electrical device is the off state; when the current health value is greater than the preset health threshold, if the target power value is greater than the first preset power threshold, determine that the target state of the electrical device is the first energy-saving state; if the target power value is less than or equal to the first preset power threshold and greater than the second preset power threshold, determine that the target state of the electrical device is the second energy-saving state; wherein the first preset power threshold is greater than the second preset power threshold; the energy-saving degree of the second energy-saving state is higher than the energy-saving degree of the first energy-saving state; if the target power value is less than or equal to the second preset power threshold, determine that the target state of the electrical device is the off state.

[0158] Optionally, the device further comprises a second control module, wherein the second control module is specifically used to control the emergency lights outside the vehicle to remain in an on state.
