[0052] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0053] Based on the problems mentioned in the above background technology, in the related technology, in the daily use of the car, there will be scenarios where the user forgets to turn off the power and leaves the car due to various reasons, or cannot return after leaving the car for a long time without turning off the power, and the user powers on the vehicle for a long time in the vehicle when the vehicle is stationary, causing the vehicle battery to be over-discharged. If the user forgets to turn off the power when getting off the vehicle, he needs to return to the vehicle to operate in order to turn off the power, which is complicated and reduces the user experience. In addition, when the battery in the vehicle is over-discharged, it will affect the battery's charging and discharging performance and life, affecting user use.

[0054] In this regard, this application provides a method for de-energizing a vehicle, please refer to Figure 1 The vehicle power recovery method provided in the embodiment of the present application includes steps 100 to 300, which are described in detail below.

[0055] Step 100, determine the battery status of the vehicle.

[0056] Step 200: If the battery status is a preset power status, determine the status of the vehicle's occupants.

[0057] Step 300: If the occupant status in the vehicle is that the occupant has left the vehicle, the vehicle is de-energized.

[0058] In this embodiment, the vehicle includes a battery, which is generally a power battery for providing a power source for the vehicle. The battery state may specifically include the battery state in multiple different dimensions, such as the battery state in the dimension of power (State Of Charge, SOC), the battery state in the dimension of charge and discharge, etc.

[0059] The preset power state refers to the state when the battery power meets the corresponding conditions. For example, the preset power state can be the state when the battery power is less than the preset power-down power threshold. The preset power-down power threshold can be set by the user. The value range of the preset power-down power threshold can be, for example, 40% to 70%. For another example, the preset power state can be the state when the battery power is less than the preset low power threshold, indicating that the battery power is too low. Among them, the preset power-down power threshold is generally less than the preset power-down power threshold. The preset power-down power threshold can be, for example, 5%.

[0060] The in-vehicle occupant status refers to the riding status of the occupants in the vehicle. For example, when there are no occupants in the vehicle, the in-vehicle occupant status may be the occupant leaving the vehicle. For another example, when there are occupants in the vehicle, the in-vehicle occupant status may be the occupant not leaving the vehicle. The occupants may be living objects such as people and pets.

[0061] In this embodiment, when the battery status is a preset power status and the occupant status is the occupant leaving the vehicle, it indicates that the occupant does not need electricity at this time, so the vehicle can be de-energized to avoid the vehicle remaining in the powered-on state and wasting electricity.

[0062] It can be seen that through the above technical solution, when the battery status of the vehicle is a preset power status and the occupant status in the vehicle is the occupant leaving the vehicle, the vehicle is de-powered to achieve active power de-powering of the vehicle when not in use, saving battery power in the vehicle, and there is no need for the occupants to return to the vehicle for power de-powering, thereby improving the user experience.

[0063] In order to avoid accidental power-off of the vehicle, in some embodiments, if the status of the occupant in the vehicle is that the occupant has left the vehicle, the vehicle is powered off, which may include: if the status of the occupant in the vehicle is that the occupant has left the vehicle, sending a power-off prompt message to a prompt message output device in the vehicle to actively remind the user; if no power-off cancellation instruction is received within the first preset time period or a power-off confirmation instruction is received within the first preset time period, the vehicle is powered off.

[0064] Among them, the prompt information output device can be a picture display device, a sound playback device, a light effect display device, etc. in the vehicle, the picture display device can be a display screen, the sound playback device can be a speaker, and the light effect display device can be an LED lamp. After the power-off prompt information is sent to the prompt information output device, the prompt information output device can output the power-off prompt information. Taking the prompt information output device as a display screen as an example, the display screen can display the interface of the power-off prompt information. Taking the prompt information output device as a speaker as an example, the speaker can play a voice including the power-off prompt information. Taking the prompt information output device as an LED lamp as an example, the LED lamp can display the lighting effect associated with the power-off prompt information. The first preset time length can be 5 minutes, for example.

[0065] In some embodiments, after sending the power-off prompt information to the prompt information output device in the vehicle, it may also include: if a power-off cancellation instruction is received within a first preset time period or a power-off confirmation instruction is not received within the first preset time period, the vehicle is kept in a powered-on state to meet the user's demand for powering on the vehicle.

[0066] In some embodiments, the triggering method of the power-off cancellation instruction and / or the power-off confirmation instruction is described. Taking the power-off prompt information displayed by the prompt information output device as an example, the power-off cancellation instruction and / or the power-off confirmation instruction are triggered based on the displayed power-off prompt information. For example, the user can perform manual operations based on the interface of the displayed power-off prompt information to trigger or not trigger the power-off cancellation instruction and / or the power-off confirmation instruction. Manual operations include click operations, sliding operations, etc.

[0067] In some embodiments, the power-off cancellation instruction is triggered by at least one of the following methods: a cancel operation on the power-off prompt information is detected, and no confirmation operation on the power-off prompt information is detected within a first preset time period; and / or, the power-off confirmation instruction is triggered by at least one of the following methods: a confirmation operation on the power-off prompt information is detected, and no cancel operation on the power-off prompt information is detected within the first preset time period.

[0068] Specifically, Figure 2 Taking the display interface of the power-off prompt information shown as an example, the display interface includes a pop-up box, and the pop-up box includes text and click controls. The text is "It is currently detected that the vehicle's battery is low. In order to save power, the vehicle will soon be powered off. Click "OK" to cancel this operation." The click controls include an "Immediately Power Off" control and an "OK" control. The "OK" control displays a countdown for the first preset duration. The user can click the "Immediately Power Off" control to perform a confirmation operation on the power-off prompt information to trigger a power-off confirmation instruction. The user can click the "OK" control to cancel the power-off prompt information to trigger a power-off cancellation instruction. In addition, if the countdown for the first preset duration ends without the user performing a click operation, the power-off confirmation instruction can be automatically triggered (that is, if the cancellation operation on the power-off prompt information is not detected within the first preset duration, the power-off confirmation instruction is automatically triggered).

[0069] by Figure 3Taking the display interface of the power-off prompt information shown as an example, the display interface includes a pop-up box, and the pop-up box includes text and click controls. The text is "It is currently detected that the vehicle has been unattended for a long time. In order to save power, the vehicle is about to power off. Click "OK" to cancel this operation." The click control includes an "OK" control, and the "OK" control displays a countdown for a first preset duration. The user can click the "OK" control to execute a cancel operation on the power-off prompt information to trigger a power-off cancellation instruction. In addition, if the countdown for the first preset duration ends without the user performing a click operation, the power-off confirmation instruction can be automatically triggered (that is, if the cancel operation on the power-off prompt information is not detected within the first preset duration, the power-off confirmation instruction is automatically triggered).

[0070] In some embodiments, the power-off cancel instruction and / or the power-off confirmation instruction may be triggered not only through a display interface but also through voice interaction, physical keys, buttons, etc., which are not limited here.

[0071] In some embodiments, the battery status of the vehicle may change during the process of outputting the power-off prompt information through the prompt information output device and waiting for the first preset time. In this regard, if no power-off cancellation instruction is received within the first preset time or a power-off confirmation instruction is received within the first preset time, power-off processing is performed on the vehicle, which may include: if no power-off cancellation instruction is received within the first preset time or a power-off confirmation instruction is received within the first preset time, re-determining the battery status of the vehicle; if the re-determined battery status is still the preset power status, power-off processing is performed on the vehicle to avoid erroneous power-off of the vehicle due to changes in the battery status.

[0072] In some embodiments, in order to make the power return of the vehicle more accurate and appropriate, the prerequisite for executing the power return process may also include a preset condition. Specifically, if the occupant status in the vehicle is the occupant leaving the vehicle, sending the power return prompt information to the prompt information output device in the vehicle may include: if the occupant status in the vehicle is the occupant leaving the vehicle and the vehicle meets the preset condition, sending the power return prompt information to the prompt information output device in the vehicle.

[0073] Among them, the preset conditions include that the vehicle is in a stationary state and / or the first target object in the vehicle is in a closed state, and the first target object includes at least one of the vehicle's doors, hood, and trunk lid. For example, the first target object may include the vehicle's four doors, hood, and trunk lid. It is understandable that when the occupant status in the vehicle is the occupant leaving the vehicle, and the vehicle is in a stationary state, and the doors, hood, and trunk lid are all closed, it indicates that the occupant leaves the vehicle not to perform related operations on the doors, hood, trunk lid, etc. outside the vehicle, but leaves the vehicle due to non-vehicle reasons, so a power-off prompt message can be sent to a prompt message output device in the vehicle.

[0074] In some embodiments, the vehicle being stationary can be determined based on the current gear position and / or current speed of the vehicle. For example, when the current gear position of the vehicle is P gear and / or the current speed is zero, the vehicle is determined to be stationary. If the current gear position of the vehicle is not P gear or the current speed is not zero, the vehicle is determined to be not stationary, thereby making the determination of the vehicle's stationary state more accurate.

[0075] In some embodiments, if the status of the occupant in the vehicle is the occupant leaving the vehicle state and the preset conditions are met, a power-off prompt message is sent to a prompt message output device in the vehicle, which may include: if the status of the occupant in the vehicle is the occupant leaving the vehicle state and the vehicle meets the preset conditions, then the duration of the occupant status in the vehicle being the occupant leaving the vehicle state and the vehicle meeting the preset conditions is obtained; if the duration is greater than or equal to the second preset duration, a power-off prompt message is sent to a prompt message output device in the vehicle to avoid the situation where the occupant briefly leaves the vehicle and the power is mistakenly turned off. Among them, when the duration is less than the second preset duration, if it is detected that the status of the occupant in the vehicle is not the occupant leaving the vehicle state or the vehicle does not meet the preset conditions, the recorded duration is cleared, so that when the status of the occupant in the vehicle is detected again as the occupant leaving the vehicle state and the vehicle meets the preset conditions, the duration is recorded again. The second preset duration can be 30 minutes, for example.

[0076] In some embodiments, in order to make the power reduction of the vehicle more accurate and appropriate, if the battery status is a preset power status, determining the status of the vehicle's passengers may include: if the battery status is a preset power status and is not charged or discharged outside the vehicle, determining the status of the vehicle's passengers, so as to facilitate the erroneous power reduction when the vehicle is charged or discharged outside the vehicle. Among them, the state of not charging or discharging outside the vehicle may include at least one of the state of not charging outside the vehicle and the state of not discharging outside the vehicle. It is understandable that in some application scenarios, the vehicle will be charged by an external charging device, or discharged by an external power device. Therefore, by judging the state of not charging or discharging outside the vehicle, it is possible to avoid the situation where the charging and discharging process of the vehicle outside the vehicle is interrupted due to the power reduction process.

[0077] In some embodiments, in some scenarios, when there are passengers in the vehicle, the vehicle may also need to be de-charged. For example, when the battery is over-discharged, the vehicle may also need to be de-charged to save battery power in the vehicle. Specifically, after determining the battery status of the vehicle, it may also include: if the battery status is an over-discharge state and the vehicle meets preset conditions, the vehicle is de-charged to avoid over-discharge of the battery in the vehicle and affect the battery's charge and discharge performance and life. Accordingly, the above step (if the battery status is a preset power state, determine the status of the vehicle's passengers) may include: if the battery status is a preset power state but not an over-discharge state, determine the status of the vehicle's passengers.

[0078] The over-discharge state is generally determined by the battery power and / or voltage. For example, when the battery power is less than a preset low-power threshold and the voltage is less than a preset low-voltage threshold, the battery state is determined to be an over-discharge state.

[0079] In some embodiments, similar to the above step (if the occupant status is the occupant leaving the vehicle, the vehicle is de-powered), if the battery status is an over-discharged state and the vehicle meets the preset conditions, the step of de-powering the vehicle can also be expanded in combination with the content in any of the above embodiments, as shown below:

[0080] If the battery status is an over-discharge state and the vehicle meets the preset conditions, the vehicle is de-powered, which may include: if the battery status is an over-discharge state and the vehicle meets the preset conditions, sending a power-off prompt message to a prompt message output device in the vehicle; if no power-off cancellation instruction is received within a first preset time period or a power-off confirmation instruction is received within a first preset time period, the vehicle is de-powered; if a power-off cancellation instruction is received within the first preset time period or a power-off confirmation instruction is not received within the first preset time period, the vehicle is kept in a powered-on state.

[0081] If the battery state is in an over-discharge state and the vehicle meets a preset condition, sending a power-off prompt message to a prompt message output device in the vehicle may include: if the battery state is in an over-discharge state and the vehicle meets a preset condition, obtaining a duration of the battery state being in an over-discharge state and the vehicle meeting the preset condition; if the duration is greater than or equal to a third preset duration, sending a power-off prompt message to a prompt message output device in the vehicle. The third preset duration may be, for example, 5 minutes.

[0082] If the battery state is an over-discharge state and the vehicle meets the preset conditions, the vehicle is de-powered, which may include: if the battery state is an over-discharge state and is not charged or discharged outside the vehicle, and the vehicle meets the preset conditions, the vehicle is de-powered.

[0083] In some embodiments, the state of the occupants in the vehicle can be determined by at least one of the driver monitoring system (Drive Monitoring System, DMS), the passenger monitoring system (Occupancy Monitoring System, OMS), the safety belt reminder (Safety Belt Reminder, SBR), the seat belt buckle (for example, the switch state of the seat belt buckle), and the vehicle occupancy detection millimeter wave radar (VoDR). Specifically, whether there are occupants in the vehicle can be detected by at least one of the driver monitoring system, the passenger monitoring system, the seat belt reminder, the seat belt buckle, and the vehicle occupant detection millimeter wave radar. If it is detected that there are no occupants in the vehicle, the state of the occupants in the vehicle is determined to be the state where the occupants have left the vehicle; if it is detected that there are occupants in the vehicle, the state of the occupants in the vehicle is determined to be the state where the occupants have not left the vehicle. Among them, the vehicle occupant detection millimeter wave radar specifically scans, compares, and analyzes the heartbeat, pulse, breathing and other actions of the vital signs targets in the vehicle to realize the identification of the occupants in the vehicle.

[0084] In some embodiments, before, after, or simultaneously with the step of de-energizing the vehicle, the step may also include: controlling a second target object in the vehicle to close, the second target object including at least one of the vehicle's windows and sunroof, and / or controlling the locking of the vehicle's doors to prevent the windows and sunroof from being open and the vehicle from being unlocked after the vehicle is de-energized, thereby preventing the vehicle from being stolen or foreign objects from entering.

[0085] In some embodiments, reference Figure 4 , is a schematic diagram of the hardware architecture for implementing the vehicle power reduction method in any embodiment. Figure 4The hardware architecture shown includes: body domain controller 1, body domain controller 2, battery management system (BMS), vehicle control unit (VCU), electronic stability program (ESP), multimedia tablet (Pad, portable android device), occupancy monitoring system (OMS), safety belt reminder (SBR), window glass lifting motor, sunroof switch motor. Body domain controller 1, body domain controller 2, battery management system, vehicle control unit, electronic stability system, multimedia tablet communicate through CANFD (Controller Area Network Flexible Data-Rate) protocol to form network 1. Body domain controller 1, body domain controller 2, multimedia tablet, occupancy monitoring system communicate through CANFD protocol to form network 2. Body domain controller 1 is also connected to the seat belt reminders of each seat in the vehicle through hard wires.

[0086] Among them, the Body Domain Control Unit (BDCU) is a regional control unit that integrates the body control system, gateway, air-conditioning control system, lighting control system, driver information control system, etc. It is a platform-based, highly integrated, and high-performance regional control unit.

[0087] exist Figure 4In the hardware architecture shown, the body domain controller 1 serves as the vehicle's power recovery device. The body domain controller 2 serves as a gateway for connecting other devices in the vehicle to achieve vehicle-wide communication. The battery management system is used to detect the battery status of the vehicle through the CANFD protocol subnet of the power battery pack information collector (Battery Information Collector, BIC). The vehicle controller is used to detect the current gear of the vehicle. The electronic stability system is used to detect the current speed of the vehicle. The passenger monitoring system and the seat belt reminder are used to detect the status of the vehicle's occupants. The body domain controller 1 is also connected to sensors for each door, trunk lid, and front hatch in the vehicle to detect whether the door, trunk lid, and front hatch are in a closed state. The body domain controller 1 is also connected to a window glass lifting motor and a sunroof switch motor to control the closing of windows and sunroofs in the vehicle. The multimedia tablet computer serves as a prompt information output device, and is used to receive and output power-off prompt information, and to feedback power-off cancellation instructions and power-off confirmation instructions to the body domain controller 1, so that the body domain controller 1 can keep the vehicle in a powered-on state according to the power-off cancellation instruction, and perform power-off processing on the vehicle according to the power-off confirmation instruction.

[0088] In addition, since the body domain controller 1 has an internal timer, the current time signal sent by the multimedia tablet computer can also be periodically used to calibrate the internal timer of the body domain controller 1. If the body domain controller 1 still does not receive the current time signal sent by the multimedia tablet computer within the preset time calibration period, or the multimedia tablet computer continuously sends multiple identical current time signals, the body domain controller 1 only uses the time of the internal timer for timing, and does not calibrate the internal timer.

[0089] Reference Figure 4 The hardware architecture shown in FIG. 1 is used to describe an example of a method for de-energizing a vehicle. Specifically, Figure 5As shown, in the scenario where the occupant leaves the vehicle for a long time without powering off, the battery management system uses the preset power-off threshold value fed back by the multimedia tablet computer to determine the battery status, and after determining that the battery status is the preset power status and is not charged or discharged outside the vehicle, sends a power-off flag signal to the body domain controller 1 through the network 1. After receiving the power-off flag signal, the body domain controller 1 determines that the occupant status in the vehicle is the occupant leaving the vehicle and that the vehicle meets the preset conditions, and then the body domain controller 1 starts the internal timing for the second preset duration, and during the timing process, the time is calibrated with the current time signal sent by the multimedia tablet computer. During the internal timing process, if the occupant status in the vehicle is the occupant not leaving the vehicle or the vehicle does not meet the preset conditions, the body domain controller 1 stops timing immediately, and restarts internal timing when it is detected again that the occupant status in the vehicle is the occupant leaving the vehicle and the vehicle meets the preset conditions. When the timing meets the second preset duration, the body domain controller 1 sends a power-off flag signal to the multimedia tablet computer. The multimedia tablet computer receives the power-off flag signal sent by the body domain controller and displays as shown. Figure 3 The interface of the power-off prompt information shown in the figure is displayed, and the first preset time is counted down. After the countdown of the first preset time is over, if the power-off cancellation instruction is not received, the multimedia tablet computer sends a power-off signal that has not been manually canceled to the battery management system through the network 1. The battery management system determines the battery status of the vehicle again. If the battery status determined again is still the preset power status, a power-off request is sent to the body domain controller 1. After receiving the power-off request, the body domain controller 1 controls the vehicle to power off, and controls the closing of the windows and sunroof of the four doors of the vehicle.

[0090] Reference Figure 4 The hardware architecture shown in FIG. 1 is used to describe another example of a method for de-energizing a vehicle. Specifically, Figure 6 As shown, in the scenario where the occupants are powered on for a long time in the vehicle without driving the vehicle, the battery management system determines that the battery status is an over-discharge state, and sends an over-discharge flag signal to the body domain controller 1 through the network 1. After the body domain controller 1 receives the over-discharge flag signal sent by the battery management system, it determines that the vehicle meets the preset conditions, and then the body domain controller 1 starts the internal timing for the third preset duration, and during the timing process, it maintains time calibration with the current time signal sent by the multimedia tablet computer. During the internal timing process, if the vehicle does not meet the preset conditions, the body domain controller 1 stops timing immediately, and restarts internal timing when it is detected again that the vehicle meets the preset conditions. When the timing meets the third preset duration, the body domain controller 1 sends an over-discharge flag signal to the multimedia tablet computer. The multimedia tablet computer receives the over-discharge flag signal sent by the body domain controller 1 and displays as shown. Figure 2The interface of the power-off prompt information shown in the figure is displayed, and the first preset time is counted down. After the first preset time countdown ends, if the power-off cancellation instruction is not received, the multimedia tablet computer sends a power-off signal that has not been manually canceled to the battery management system through the network 1. The battery management system determines the battery status of the vehicle again. If the battery status determined again is still in the over-discharge state, a power-off request is sent to the body domain controller 1. After receiving the power-off request, the body domain controller 1 controls the vehicle to power off.
