Description

Technical Field

[0001] The present application relates to the field of vehicle control technology, and in particular to a power control method, device, electronic equipment and vehicle. Background Art

[0002] The current power mode management of the sensorless start model relies on the switch state of the seat occupancy switch to identify whether the user is in the car, and then control the switching of the vehicle's power mode. Specifically, when someone sits on the seat, the pressure acting on the seat is greater than or equal to a certain threshold, and the occupancy switch under the seat is closed and turned on. At this time, the vehicle's power management system recognizes that there is a person in the car. If the user opens the door, the vehicle will not be powered on. When no one is sitting on the seat, the pressure acting on the seat is less than a certain threshold, the occupancy switch under the seat will be in a high-impedance state. At this time, when the user opens the door, the vehicle will be powered on.

[0003] However, as the vehicle ages, the seat may deform or otherwise age, causing the detection accuracy of the occupancy switch under the seat to decrease, making it unable to accurately identify whether someone is sitting in the seat. This misjudgment can cause unexpected power mode switching, such as the vehicle accidentally shutting down when the user is not leaving, or failing to shut down in time after the user leaves. These situations not only reduce the reliability of the vehicle, but may also cause users to be dissatisfied with and complain about the vehicle's functions.

[0004] In addition, the existing power mode management method of the sensorless start vehicle model requires the additional addition of a driver's seat occupant switch and a wiring harness connecting the occupant switch, which increases the design cost and manufacturing cost of the entire vehicle to a certain extent. Summary of the invention

[0005] In view of the above, it is necessary to propose a power control method, device, electronic device and vehicle to solve the technical problem that the power mode management method of the existing sensorless start vehicle model relies on the seat occupancy switch, resulting in redundant production costs and reduced reliability of the vehicle.

[0006] In a first aspect, the present application provides a power control method, which is applied to a vehicle, and the method includes: if a preset in-vehicle power-off trigger operation is detected, controlling the vehicle to enter a high-voltage power-off state, and executing a preset restricted power-on operation, wherein the restricted power-on operation is used to limit the vehicle from switching from the high-voltage power-off state to the high-voltage power-on state when a door opening signal is detected; in response to a preset external power-off trigger operation, controlling the vehicle to enter an armed state, and releasing the restricted power-on operation.

[0007] In the power control method of the above embodiment, first, if a preset in-vehicle power-off trigger operation is detected, the vehicle is controlled to enter a high-voltage power-off state, and a preset restricted power-on operation is performed, so that when a door opening signal is detected, the vehicle is restricted from switching from the high-voltage power-off state to the high-voltage power-on state, which effectively solves the problem of unexpected power-on of the vehicle's power mode due to the user opening the door from inside the vehicle when the vehicle is in the high-voltage power-off state when the placeholder switch fails or the placeholder switch is cancelled, thereby improving the reliability and stability of the vehicle's power control, reducing the risks caused by component failure or design limitations, and reducing the production cost of the vehicle. Then, in response to the preset external power-off trigger operation, the vehicle is controlled to enter the armed state and the restricted power-on operation is lifted, thereby realizing the lifting of the restricted power-on operation through the user's external power-off trigger operation without adding additional hardware equipment such as sensors. The user does not need to perform additional active power-on operations and can use the vehicle normally after opening the door again. The lifting of the restricted power-on operation is combined with the user's external power-off trigger operation, which simplifies the user's operating process. Without increasing the user's burden and affecting the normal function of the vehicle, it realizes smarter and more efficient power management, reduces the production cost of the vehicle while ensuring the user's vehicle experience.

The vehicle also includes a power system, an intelligent cockpit system, an intelligent driving system, and a chassis system. The obtaining of the power demand of each of the multiple domain controllers includes: obtaining the operating parameters of the power system through the power domain controller, and judging whether the power system has power demand based on the operating parameters of the power system; obtaining the operating parameters of the intelligent cockpit system through the cockpit domain controller, and judging whether the intelligent cockpit system has power demand based on the operating parameters of the intelligent cockpit system; obtaining the operating parameters of the intelligent driving system through the driving domain controller, and judging whether the intelligent driving system has power demand based on the operating parameters of the intelligent driving system; obtaining the operating parameters of the chassis system through the chassis domain controller, and judging whether the chassis system has power demand based on the operating parameters of the chassis system.

[0030] See also Figure 1 , is a schematic diagram of an application scenario of a power control method provided in an embodiment of the present application.

[0031] The embodiment of the present application provides a power control method, which can be applied to one or more electronic devices 10. The electronic device 10 is a device that can automatically perform numerical calculations and / or information processing according to pre-set or stored instructions, and its hardware includes but is not limited to a microprocessor, an application specific integrated circuit (Application Specific Integrated Circuit, ASIC), a field-programmable gate array (Field-Programmable Gate Array, FPGA), a digital processor (Digital Signal Processor, DSP), an embedded device, etc.

[0032] The embodiment of the present application further provides a vehicle 1, which includes an electronic device 10. The electronic device 10 may be an onboard device of the vehicle 1, such as a body control module (BCM), a vehicle control unit (VCU), and the like.

[0033] Specifically, the electronic device 10 is used to: if a preset in-vehicle power-off trigger operation is detected, control the vehicle 1 to enter a high-voltage power-off state, and execute a preset restricted power-on operation, wherein the restricted power-on operation is used to restrict the vehicle 1 from switching from the high-voltage power-off state to the high-voltage power-on state when a door opening signal is detected; in response to a preset out-vehicle power-off trigger operation, control the vehicle 1 to enter a defense state, and release the restricted power-on operation.

[0034] In some embodiments of the present application, the electronic device 10 can be communicatively connected to a desktop computer, a notebook, a PDA, a cloud server, or other devices.

[0035] In some embodiments of the present application, the electronic device 10 can perform human-computer interaction with the user through a keyboard, a mouse, a remote control, a touch pad, or a voice control device.

[0036] In some embodiments of the present application, the electronic device 10 may further include a network device and / or a client device. Among them, the network device includes but is not limited to a single network server, a server group composed of multiple network servers, and a cloud server composed of a large number of hosts or network servers based on cloud computing (Cloud Computing).

[0037] In some embodiments of the present application, the network where the electronic device 10 is located includes but is not limited to the Internet, wide area network, metropolitan area network, local area network, virtual private network (Virtual Private Network, VPN), etc.

[0038] Please refer to Figure 2 , which is a schematic diagram of the steps of the power control method provided by an embodiment of the present application.

[0039] Specifically, the power control method specifically includes the following steps. According to different requirements, the order of some steps in this flowchart can be changed, and some steps can be omitted.

[0040] Step S10, if a preset in-vehicle power-off trigger operation is detected, control the vehicle to enter the high-voltage power-off state and perform a preset power-on restriction operation.

[0041] It should be noted that the vehicle 1 entering the high-voltage power-off state means that the high-voltage battery (such as a lithium-ion battery) of the vehicle 1 no longer provides power for high-voltage components such as the drive motor, high-voltage control system, and air-conditioning compressor.

[0042] In some embodiments of the present application, the in-vehicle power-off trigger operation includes at least one of the following operations: detecting a user's power-off operation, detecting a user's braking operation on the brake pedal of the vehicle 1, and detecting that the pressing duration of the user on the hazard warning button of the vehicle 1 exceeds a preset duration, detecting that the vehicle 1 has no power demand, and the duration is greater than a preset time threshold, receiving a preset diagnostic instruction.

[0043] The user's power-off operation includes but is not limited to the user sending a power-off instruction by pressing a virtual button (such as a soft switch) or a physical button (such as a start-stop button) of the vehicle 1. When the vehicle 1 is in the high-voltage power-on state, when the user long-presses or short-presses the virtual button or the physical button, the electronic device 10 will recognize the power-off instruction, and then control the vehicle 1 to enter the high-voltage power-off state.

[0044] When an emergency occurs or there is a temporary parking requirement, the user will step on the brake pedal and press the hazard warning button. Then, when the electronic device 10 detects the user's braking operation on the brake pedal of the vehicle 1 and the pressing duration of the user on the hazard warning button of the vehicle 1 exceeds a preset duration (such as 7s), it indicates that there may be an emergency or a temporary parking requirement. Then, the vehicle 1 can be controlled to enter the high-voltage power-off state to ensure vehicle use safety.

[0045] When it is detected that vehicle 1 has no power demand and the duration is longer than a preset time threshold (e.g. 20 minutes), it indicates that vehicle 1 has not been used for a long time and has no power demand. Then, vehicle 1 can be controlled to enter a high-voltage power-off state to avoid excessive discharge of the battery. For how to determine whether vehicle 1 has power demand, please refer to Figure 3 The detailed description of step 20 shown is not repeated here to avoid repetition.

[0046] During the repair, maintenance or fault diagnosis of vehicle 1, the maintenance personnel or diagnostic equipment will send a specific diagnostic instruction, such as 2F, to vehicle 1 to trigger the power-off operation. When the electronic device 10 receives this diagnostic instruction, it controls vehicle 1 to enter a high-voltage power-off state. This triggering method is mainly used in professional maintenance scenarios to ensure that vehicle 1 is in a safe high-voltage power-off state during maintenance or diagnostic operations to prevent safety hazards caused by high voltage electricity.

[0047] It should be noted that the in-vehicle power-off trigger operation includes all operations related to the power-off trigger operation in the vehicle 1, and this application does not impose any restrictions on this.

[0048] In some embodiments of the present application, the power-on restriction operation is used to restrict the vehicle 1 from switching from the high-voltage power-off state to the high-voltage power-on state when a door opening signal is detected.

[0049] Specifically, a door-opening power-on prohibition flag is pre-set in the computer program of the electronic device 10, and the door-opening power-on prohibition flag is used to control the power-on behavior of the vehicle 1 when a door opening signal is detected. Then, the specific steps of executing the preset restricted power-on operation include: setting the preset door-opening power-on prohibition flag. When the door-opening power-on prohibition flag is set, the electronic device 10 restricts the vehicle 1 from switching from the high-voltage power-off state to the high-voltage power-on state when the door opening signal is detected, that is, the vehicle 1 is prohibited from automatically switching from the high-voltage power-off state to the high-voltage power-on state due to the door opening.

[0050] In some embodiments of the present application, the vehicle 1 further includes a switch sensor 20, and the electronic device 10 is in communication with the switch sensor 20. The switch sensor 20 is used to monitor the switch state of the door in real time. When any door is opened, the switch sensor 20 sends a door opening signal to the electronic device 10.

[0051] Step S11, in response to a preset external power-off triggering operation, the vehicle is controlled to enter a defense state, and the restriction on the power-on operation is released.

[0052] In some embodiments of the present application, the external power-off trigger operation includes at least one of the following operations: detecting a car lock signal emitted by a remote control key, detecting a car lock signal emitted by a mobile phone, detecting a keyless car lock signal, and detecting a leave car lock signal.

[0053] It should be noted that the off-vehicle power-off triggering operation includes all operations related to the power-off triggering operation performed inside the vehicle 1, and this application does not impose any restrictions on this.

[0054] In some embodiments of the present application, the vehicle 1 entering the fortified state means locking the vehicle 1 (eg, automatically locking the doors, closing the windows, etc.) and activating the anti-theft system to prevent illegal intrusion.

[0055] Specifically, the specific steps of lifting the restricted power-on operation include: clearing the door opening prohibition power-on flag. When the door opening prohibition power-on flag is cleared, the electronic device 10 allows the vehicle 1 to switch from the high-voltage power-off state to the high-voltage power-on state when detecting the door opening signal, that is, the vehicle 1 is allowed to automatically switch from the high-voltage power-off state to the high-voltage power-on state due to the door opening.

[0056] In the power control method of the above embodiment, first, if a preset in-vehicle power-off trigger operation is detected, the vehicle 1 is controlled to enter a high-voltage power-off state, and a preset restricted power-on operation is performed, so that when a door opening signal is detected, the vehicle 1 is restricted from switching from the high-voltage power-off state to the high-voltage power-on state, which effectively solves the problem of unexpected power-on of the power mode of the vehicle 1 due to the user opening the door from inside the vehicle when the occupant switch fails or the occupant switch is cancelled, thereby improving the reliability and stability of the power control of the vehicle 1, reducing the risks caused by component failure or design limitations, and reducing the production cost of the vehicle 1. Then, in response to the preset external power-off trigger operation, the vehicle 1 is controlled to enter the armed state and the restricted power-on operation is lifted, thereby realizing the lifting of the restricted power-on operation through the user's external power-off trigger operation without adding additional hardware equipment such as sensors. The user does not need to perform additional active power-on operations and can use the vehicle 1 normally after opening the door again. The lifting of the restricted power-on operation is combined with the user's external power-off trigger operation, which simplifies the user's operating process. Without increasing the user's burden and affecting the normal function of the vehicle 1, it realizes smarter and more efficient power management, reduces the production cost of the vehicle 1, and can also ensure the user's vehicle experience.

[0057] In some embodiments of the present application, after releasing the restricted power-on operation, the power control method further includes: Step S12: If a preset unlocking trigger operation is detected, the vehicle is controlled to switch from the armed state to the disarmed state.

[0058] In some embodiments of the present application, the unlock trigger operation includes at least one of the following operations: detecting an unlock signal sent by a remote control key, detecting an unlock signal sent by a mobile phone, detecting a keyless unlock signal, and detecting a proximity unlock signal.

[0059] It should be noted that the unlocking triggering operation includes all unlocking operations performed outside the vehicle 1, and this application does not impose any restrictions on this.

[0060] In some embodiments of the present application, the vehicle 1 entering the disarmed state means disabling the anti-theft system and unlocking the vehicle 1 , allowing the user to use the vehicle 1 normally.

[0061] Step S13: If a door opening signal is detected, the vehicle is controlled to switch from a high voltage power-off state to a high voltage power-on state.

[0062] Specifically, when vehicle 1 is in the disarmed state, if the user opens any door, vehicle 1 will automatically switch from the high-voltage power-off state to the high-voltage power-on state, so that the vehicle computer of vehicle 1 can work normally, and functions such as air conditioning and lighting can be used normally.

[0063] In the above embodiment, after the restriction on the power-on operation is lifted, the user can use the vehicle 1 normally after opening the door again without performing additional active power-on operations. Without increasing the burden on the user and without affecting the normal function of the vehicle 1, smarter and more efficient power management is achieved, which reduces the production cost of the vehicle 1 while ensuring the user's car experience.

[0064] In some embodiments of the present application, after executing the preset restricted power-on operation, the power control method further includes: if a brake signal from the brake pedal of vehicle 1 is detected and a legitimate key corresponding to vehicle 1 is identified, controlling vehicle 1 to switch from a high-voltage power-off state to a high-voltage power-on state.

[0065] Specifically, the vehicle 1 further includes a pressure sensor 30, and the electronic device 10 is in communication connection with the pressure sensor 30. The pressure sensor 30 is used to monitor the state of the brake pedal in real time. When the user steps on the brake pedal, the pressure sensor 30 sends a brake signal to the electronic device 10.

[0066] Among them, the legal keys corresponding to the vehicle 1 include but are not limited to remote control keys, smart keys (such as keyless entry systems, Bluetooth keys, etc.), electronic keys (such as card keys), etc.

[0067] In the above embodiments, when the user has a power-on requirement, the brake pedal can be stepped on, and then the pressure sensor 30 sends a braking signal to the electronic device 10. When the electronic device 10 detects the braking signal of the brake pedal and identifies the legal key corresponding to the vehicle 1, it indicates that the user has a power-on requirement and is a legal user, and controls the vehicle 1 to switch from the high-voltage power-off state to the high-voltage power-on state, improving the flexibility of the power control of the vehicle 1 and the user experience.

[0068] In some embodiments of the present application, the power control method further includes: if an out-of-vehicle power-off trigger operation is detected when the vehicle 1 is in the high-voltage power-on state and the parking state, controlling the vehicle 1 to switch from the high-voltage power-on state to the high-voltage power-off state.

[0069] Among them, when the vehicle 1 has stopped and is in the parking gear (for example, the P gear), it indicates that the vehicle 1 is in the parking state. When the vehicle 1 is in the high-voltage power-on state and the parking state and an out-of-vehicle power-off trigger operation is detected, it indicates that the user is not in the vehicle 1 and has a power-off requirement, and then controls the vehicle 1 to switch from the high-voltage power-on state to the high-voltage power-off state.

[0070] In the above implementation, when the vehicle 1 is in the high-voltage power-on state and the parking state, if the user issues an out-of-vehicle power-off trigger operation, it indicates that the user is not in the vehicle 1 and has a power-off requirement. The vehicle 1 can accurately respond and switch to the high-voltage power-off state, reducing unnecessary power consumption, helping to extend the battery life of the vehicle 1, and improving energy utilization efficiency.

[0071] Please refer to Figure 3 , which is a schematic diagram of the steps of the power control method provided by another embodiment of the present application.

[0072] Specifically, the power control method specifically includes the following steps. According to different requirements, the order of some steps in this flowchart can be changed, and some steps can be omitted.

[0073] Step S20, if the vehicle enters the high-voltage power-on state, obtain the power consumption requirements of each domain controller among multiple domain controllers.

[0074] In some embodiments of the present application, the multiple domain controllers include, but are not limited to, a power domain controller 40, a cockpit domain controller 50, a driving domain controller 60, and a chassis domain controller 70. The vehicle 1 further includes a power system 41, an intelligent cockpit system 51, an intelligent driving system 61, and a chassis system 71. Among them, the electronic device 10 is communicatively connected to the power domain controller 40, the cockpit domain controller 50, the driving domain controller 60, and the chassis domain controller 70. The power domain controller 40 is used to control the power system 41, the cockpit domain controller 50 is used to control the intelligent cockpit system 51, the driving domain controller 60 is used to control the intelligent driving system 61, and the chassis domain controller 70 is used to control the chassis system 71.

[0075] In some embodiments of the present application, the specific steps for obtaining the power consumption requirements of each domain controller among multiple domain controllers include: obtaining the operating parameters of the power system 41 through the power domain controller 40, and determining whether the power system 41 has a power consumption requirement based on the operating parameters of the power system 41.

[0076] Specifically, the power domain controller 40 mainly determines whether the power system 41 has a power consumption requirement based on operating parameters such as the charge and discharge state of the vehicle 1, the battery temperature maintenance state, and the power preparation state, and feeds back the power consumption requirement to the electronic device 10. For example, when the power domain controller 40 detects that the vehicle 1 is in a discharge state, it is determined that the power system 41 has a power consumption requirement.

[0077] In some embodiments of the present application, the specific steps for obtaining the power consumption requirements of each domain controller among multiple domain controllers further include: obtaining the operating parameters of the intelligent cockpit system 51 through the cockpit domain controller 50, and determining whether the intelligent cockpit system 51 has a power consumption requirement based on the operating parameters of the intelligent cockpit system 51.

[0078] Specifically, the cockpit domain controller 50 mainly determines whether the intelligent cockpit system 51 has a power consumption requirement based on operating parameters such as the entertainment needs of the user (such as movie-watching needs), the start-stop state under the condition of leaving the vehicle without high-voltage power-off, the start-stop state of the nap mode, and the living object detection information, and feeds back the power consumption requirement to the electronic device 10. For example, when the cockpit domain controller 50 detects the entertainment needs of the user, it is determined that the intelligent cockpit system 51 has a power consumption requirement.

[0079] In some embodiments of the present application, the specific steps for obtaining the power consumption requirements of each domain controller among multiple domain controllers further include: obtaining the operating parameters of the intelligent driving system 61 through the driving domain controller 60, and determining whether the intelligent driving system 61 has a power consumption requirement based on the operating parameters of the intelligent driving system 61.

[0080] Specifically, the driving domain controller 60 mainly determines whether the intelligent driving system 61 has a power consumption requirement based on operating parameters such as the automatic parking request, and feeds back the power consumption requirement to the electronic device 10. For example, when the driving domain controller 60 detects an automatic parking request, it is determined that the intelligent driving system 61 has a power consumption requirement.

[0081] In some embodiments of the present application, the specific steps for obtaining the power consumption requirements of each domain controller among multiple domain controllers further include: obtaining the operating parameters of the chassis system 71 through the chassis domain controller 70, and determining whether the chassis system 71 has a power consumption requirement based on the operating parameters of the chassis system 71.

[0082] Specifically, the chassis domain controller 70 mainly determines whether there is an electricity demand in the chassis system 71 based on operating parameters such as motor current and motor speed, and feeds back the electricity demand to the electronic device 10. For example, when the chassis domain controller 70 detects that the motor current is greater than the preset current, it determines that there is an electricity demand in the chassis system 71.

[0083] In the above embodiments, the power domain controller 40, the cockpit domain controller 50, the driving domain controller 60, and the chassis domain controller 70 jointly detect the electricity demand of the vehicle 1, making up for the deficiency that a single domain controller is not accurate enough in judging the user's electricity demand. For example, when the user watches a movie in the vehicle, the vehicle 1 actively triggers a power-down reminder, resulting in a poor user experience. Multiple domain controllers jointly participate in judging the user's electricity demand, identifying more scenarios and reducing signal interaction, thereby improving the detection efficiency and accuracy of the electricity demand.

[0084] Step S21, if each domain controller has no electricity demand, after an interval of the first preset duration, a reminder message is sent.

[0085] Among them, the reminder message is used to prompt the user to confirm whether to continue using electricity.

[0086] In some embodiments of the present application, the first preset duration can be 19 minutes.

[0087] In some embodiments of the present application, the electronic device 10 can remind the user whether to continue using electricity through the central control screen, or the instrument panel, or the voice assistant, etc.

[0088] Specifically, when the electronic device 10 determines that each domain controller has no electricity demand, after an interval of 19 minutes, it sends a reminder message through the central control screen, or the instrument panel, or the voice assistant to remind the user whether to continue using electricity.

[0089] Step S22, detect whether an instruction for the user to confirm continuing to use electricity is received.

[0090] In some embodiments of the present application, if an instruction for the user to confirm continuing to use electricity is not received, the electronic device 10 continues to execute step S23.

[0091] In some embodiments of the present application, if an instruction for the user to confirm continuing to use electricity is received, the electronic device 10 continues to execute step S24.

[0092] Step S23, after an interval of the second preset duration, control the vehicle to switch from the high-voltage power-on state to the high-voltage power-off state.

[0093] In some embodiments of the present application, the second preset duration can be 1 minute.

[0094] In some embodiments of the present application, if the user issues a cancellation power consumption instruction or does not perform any operation through the central control screen, or the instrument panel, or the voice assistant, that is, the electronic device 10 does not receive an instruction from the user to confirm continued power consumption, the vehicle 1 is controlled to switch from the high-voltage power-on state to the high-voltage power-off state after an interval of 1 minute.

[0095] Step S24, control the vehicle to maintain the high-voltage power-on state, and obtain the remaining power and operation information of the vehicle.

[0096] Specifically, the vehicle 1 further includes a battery management system 80, and the electronic device 10 is communicatively connected to the battery management system 80. The battery management system 80 monitors the charging and discharging current of the battery in real time, calculates the charging and discharging amount of the battery by real-time integration, calculates the remaining power percentage of the vehicle 1 based on the following calculation formula, and then calculates the remaining power (unit: ampere-hour, Ah) according to the product of the remaining power percentage and the rated capacity of the battery.

[0097] Wherein, SOC(t) is the remaining power percentage of the battery at the current moment, and SOC(t0) is the remaining power percentage of the battery at the initial moment. I(t) is the charging and discharging current of the battery (positive value for charging, negative value for discharging), and C is the rated capacity of the battery (unit: ampere-hour, Ah).

[0098] Step S25, determine the available duration of the remaining power according to the operation information, and display the remaining power and the available duration through the vehicle's interaction interface.

[0099] Specifically, the electronic device 10 determines the total power consumption of the vehicle 1 according to the operation information, including but not limited to the total power consumption of the intelligent cockpit system 51, the intelligent driving system 61, the vehicle machine system, the air conditioning system, the lighting system, etc. According to the current remaining power of the battery and the total power consumption of the vehicle 1, the following calculation formula is used to calculate the available duration of the remaining power: T = (remaining power × voltage) / total power consumption × 60.

[0100] Wherein, T is the available duration of the remaining power (unit: minute, min), the battery voltage is the current voltage of the battery (unit: volt, V), and the total power consumption is the current total power consumption of the vehicle 1 (unit: watt, W).

[0101] In the above embodiments, after each domain controller has no power mode maintenance requirement, the electronic device 10 sets a countdown mechanism, which can effectively avoid the situation that when all domain controllers have no power state maintenance requirement, the user is still in the vehicle but the vehicle 1 immediately powers off. Before powering off, a text pop-up window or voice reminder is given to the user through the central control screen, or the instrument panel, or the voice assistant, so that the user can actively choose whether to power off, improving the flexibility of power control and the user experience.

[0102] Please refer to Figure 4 , which is a schematic diagram of the functional modules of the power control device 100 provided in an embodiment of the present application.

[0103] In this embodiment, based on the same concept as the power control method in the above Figure 2 shown embodiment, the present application also provides a power control device 100, which can be used to execute the above power control method. For the convenience of description, in the schematic diagram of the composition of the embodiment of the power control device 100, only the parts related to the embodiment of the present application are shown. Those skilled in the art can understand that the illustrated structure does not constitute a limitation on the power control device 100, and it may include more or fewer components than those illustrated, or combine some components, or have different component arrangements.

[0104] Specifically, the power control device 100 provided in the embodiment of the present application includes an execution module 110 and a release module 120.

[0105] The acquisition module 110 is used to control the vehicle 1 to enter the high-voltage power-off state and execute a preset power-on restriction operation if a preset in-vehicle power-off trigger operation is detected.

[0106] It should be noted that the vehicle 1 entering the high-voltage power-off state means that the high-voltage battery (such as a lithium-ion battery) of the vehicle 1 no longer provides power to high-voltage components such as the drive motor, the high-voltage control system, and the air-conditioning compressor.

[0107] In some embodiments of the present application, the in-vehicle power-off trigger operation includes at least one of the following operations: detecting a user's power-off operation, detecting a user's braking operation on the brake pedal of the vehicle 1, and detecting that the pressing duration of the user on the hazard warning button of the vehicle 1 exceeds a preset duration, detecting that the vehicle 1 has no power demand and the duration is greater than a preset time threshold, and receiving a preset diagnostic instruction.

[0108] The user's power-off operation includes, but is not limited to, the user issuing a power-off instruction by pressing a virtual button (such as a soft switch) or a physical button (such as a start-stop button) of the vehicle 1. When the vehicle 1 is in the high-voltage power-on state, if the user long-presses or short-presses the virtual button or the physical button, the electronic device 10 will recognize the power-off instruction and then control the vehicle 1 to enter the high-voltage power-off state.

[0109] When an emergency or a temporary parking requirement occurs, the user will step on the brake pedal and press the hazard warning button. Then, when the electronic device 10 detects the user's braking operation on the brake pedal of the vehicle 1 and the pressing duration of the user on the hazard warning button of the vehicle 1 exceeds a preset duration (such as 7 s), it indicates that there may be an emergency or a temporary parking requirement, and then the vehicle 1 can be controlled to enter the high-voltage power-off state to ensure the safety of vehicle use.

[0110] When it is detected that vehicle 1 has no power demand and the duration is longer than a preset time threshold (e.g. 20 minutes), it indicates that vehicle 1 has not been used for a long time and has no power demand. Then, vehicle 1 can be controlled to enter a high-voltage power-off state to avoid excessive discharge of the battery. For how to determine whether vehicle 1 has power demand, please refer to Figure 3 The detailed description of step 20 shown is not repeated here to avoid repetition.

[0111] During the repair, maintenance or fault diagnosis of vehicle 1, the maintenance personnel or diagnostic equipment will send a specific diagnostic instruction, such as 2F, to vehicle 1 to trigger the power-off operation. When the electronic device 10 receives this diagnostic instruction, it controls vehicle 1 to enter a high-voltage power-off state. This triggering method is mainly used in professional maintenance scenarios to ensure that vehicle 1 is in a safe high-voltage power-off state during maintenance or diagnostic operations to prevent safety hazards caused by high voltage electricity.

[0112] It should be noted that the in-vehicle power-off trigger operation includes all operations related to the power-off trigger operation in the vehicle 1, and this application does not impose any restrictions on this.

[0113] In some embodiments of the present application, the power-on restriction operation is used to restrict the vehicle 1 from switching from the high-voltage power-off state to the high-voltage power-on state when a door opening signal is detected.

[0114] Specifically, a door-opening power-on prohibition flag is pre-set in the computer program of the electronic device 10, and the door-opening power-on prohibition flag is used to control the power-on behavior of the vehicle 1 when a door opening signal is detected. Then, the specific steps of executing the preset restricted power-on operation include: setting the preset door-opening power-on prohibition flag. When the door-opening power-on prohibition flag is set, the electronic device 10 restricts the vehicle 1 from switching from the high-voltage power-off state to the high-voltage power-on state when the door opening signal is detected, that is, the vehicle 1 is prohibited from automatically switching from the high-voltage power-off state to the high-voltage power-on state due to the door opening.

[0115] In some embodiments of the present application, the vehicle 1 further includes a switch sensor 20, and the electronic device 10 is in communication with the switch sensor 20. The switch sensor 20 is used to monitor the switch state of the door in real time. When any door is opened, the switch sensor 20 sends a door opening signal to the electronic device 10.

[0116] The release module 120 is used to control the vehicle to enter the armed state and release the restricted power-on operation in response to a preset external power-off trigger operation.

[0117] In some embodiments of the present application, the external power-off trigger operation includes at least one of the following operations: detecting a car lock signal emitted by a remote control key, detecting a car lock signal emitted by a mobile phone, detecting a keyless car lock signal, and detecting a leave car lock signal.

[0118] It should be noted that the off-vehicle power-off triggering operation includes all operations related to the power-off triggering operation performed inside the vehicle 1, and this application does not impose any restrictions on this.

[0119] In some embodiments of the present application, the vehicle 1 entering the fortified state means locking the vehicle 1 (eg, automatically locking the doors, closing the windows, etc.) and activating the anti-theft system to prevent illegal intrusion.

[0120] Specifically, the specific steps of lifting the restricted power-on operation include: clearing the door opening prohibition power-on flag. When the door opening prohibition power-on flag is cleared, the electronic device 10 allows the vehicle 1 to switch from the high-voltage power-off state to the high-voltage power-on state when detecting the door opening signal, that is, the vehicle 1 is allowed to automatically switch from the high-voltage power-off state to the high-voltage power-on state due to the door opening.

[0121] In the power control device 100 of the above embodiment, first, if a preset in-vehicle power-off trigger operation is detected, the vehicle 1 is controlled to enter a high-voltage power-off state, and a preset restricted power-on operation is performed, so that when a door opening signal is detected, the vehicle 1 is restricted from switching from the high-voltage power-off state to the high-voltage power-on state, which effectively solves the problem of unexpected power-on of the power mode of the vehicle 1 due to the user opening the door from inside the vehicle when the occupant switch fails or the occupant switch is cancelled, thereby improving the reliability and stability of the power control of the vehicle 1, reducing the risks caused by component failure or design limitations, and reducing the production cost of the vehicle 1. Then, in response to the preset external power-off trigger operation, the vehicle 1 is controlled to enter the armed state and the restricted power-on operation is lifted, thereby realizing the lifting of the restricted power-on operation through the user's external power-off trigger operation without adding additional hardware equipment such as sensors. The user does not need to perform additional active power-on operations and can use the vehicle 1 normally after opening the door again. The lifting of the restricted power-on operation is combined with the user's external power-off trigger operation, which simplifies the user's operating process. Without increasing the user's burden and affecting the normal function of the vehicle 1, it realizes smarter and more efficient power management, reduces the production cost of the vehicle 1, and can also ensure the user's vehicle experience.
