Description

Technical Field

[0001] This invention relates to the field of vehicle networking, and more specifically, to a method, apparatus, and vehicle for processing vehicle power-off. Background Technology

[0002] Current methods for controlling high-voltage power-off in vehicles typically involve the vehicle recognizing the driver's intention to power off from inside the passenger compartment, at which point a high-voltage relay disconnects. This disconnection action is always accompanied by the mechanical sound of the relay. With the increasing prevalence of intelligent vehicle functions, scenarios involving automatic high-voltage power-on and power-off for battery charging are becoming more common. This leads to more instances where users hear relay sounds inside the vehicle, impacting the user experience and resulting in significant noise during high-voltage power-off.

[0003] There is currently no effective solution to the above problems. Summary of the Invention

[0009] Optionally, in response to the battery not needing to be recharged, or in response to the risk of the power battery being depleted, the vehicle is powered off according to the second mode.

[0010] Optionally, the vehicle can be powered down in the second mode, including: controlling the relay in the vehicle's high-voltage power distribution module to disconnect and outputting a target audio signal to the vehicle.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0024] Example 1

[0025] According to an embodiment of the present invention, a method for processing a vehicle power-off is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0026] Figure 1 This is a flowchart of a vehicle power-off processing method according to an embodiment of the present invention, as shown below. Figure 1 As shown, the method includes the following steps:

[0027] Step S102: In response to receiving a power-down command to the vehicle, the vehicle is monitored and a monitoring result is obtained, wherein the monitoring result is used to characterize whether a user is inside the vehicle.

[0028] The aforementioned vehicle can be any type of new energy vehicle equipped with Sentry Mode, and is not specifically limited in this embodiment. It should be noted that Sentry Mode involves real-time video recording of the vehicle using both in-vehicle and external cameras, allowing users to monitor the vehicle in real-time via an application. Users can remotely activate or deactivate Sentry Mode. The aforementioned power-down command can be a remotely issued power-down command by the user, or a power-down command generated after the user performs a power-down operation inside the vehicle, but is not limited to these. The aforementioned user can be any occupant inside the vehicle, including but not limited to: the driver and passengers.

[0029] In one optional embodiment, when the vehicle needs to be powered down, the user can first perform a power-down operation on the vehicle remotely or inside the vehicle. Then, in response to the user's power-down operation, a corresponding power-down command can be generated. After receiving the power-down command, the camera installed on the vehicle can be controlled to monitor the interior of the vehicle and obtain the monitoring results of whether there are occupants inside the vehicle.

[0030] It should be noted that monitoring of occupants inside the vehicle is not limited to cameras; it can also be any sensor, processor, or other device capable of determining whether there are occupants inside the vehicle. This embodiment does not impose any limitations on this method.

[0031] Step S104: Obtain the vehicle status, wherein the vehicle status includes at least the vehicle's target mode status.

[0032] The target mode state mentioned above can be the state of whether the vehicle has Sentry Mode enabled, but it is not limited to this.

[0033] In one optional embodiment, after receiving the power-down command of the vehicle, the vehicle status can also be obtained at the same time. Based on the target mode status in the vehicle status, it can be determined whether to activate the sentry mode, but it is not limited to this.

[0034] Step S106: Based on the monitoring results and vehicle status, power off the vehicle.

[0035] In one optional embodiment, after obtaining the monitoring results and vehicle status, the specific power-down method for the vehicle can be determined based on these results. For example, when the monitoring result indicates that there are occupants in the vehicle, the high voltage can be converted to a low voltage and transmitted to the battery, then the vehicle's relay can be disconnected, and audio / video can be played simultaneously to achieve noise reduction power-down. Alternatively, when no occupants are detected in the vehicle, noise reduction power-down can be achieved by playing audio / video during the relay disconnection process. Another example is when occupants are detected in the vehicle and the vehicle is in sentry mode, the high voltage can be converted to a low voltage and transmitted to the battery, then the vehicle's relay can be disconnected, and audio / video can be played simultaneously to achieve noise reduction power-down. Yet another example is when no occupants are detected in the vehicle and the vehicle is not in sentry mode, noise reduction power-down can be achieved by playing audio / video during the relay disconnection process, but this is not limited to these methods.

[0036] In this embodiment of the invention, the method involves monitoring the vehicle in response to a received power-down command, obtaining monitoring results, acquiring the vehicle's status, and then powering down the vehicle based on the monitoring results and the vehicle status. It is readily apparent that by using the monitoring results and the vehicle status, different modes can be used to power down the vehicle with reduced noise, achieving an effective goal of noise reduction during power-down. This reduces the noise during high-voltage power-down of the vehicle, thus solving the technical problem of excessive noise during high-voltage power-down of vehicles in related technologies.

[0037] Optionally, based on the monitoring results and vehicle status, powering down the vehicle includes: powering down the vehicle according to a first mode in response to the monitoring results indicating that a user is inside the vehicle or the target mode is sentry mode; and powering down the vehicle according to a second mode in response to the monitoring results indicating that no user is inside the vehicle and the target mode is not sentry mode.

[0038] The first mode described above can be a user-preset noise-reduction power-off mode. This mode converts the high voltage of the power battery to a low voltage and transmits it to the storage battery. Then, it controls the vehicle's relays to disconnect and simultaneously outputs audio and video to the vehicle, achieving the purpose of noise-reduction power-off. The second mode described above can also be a user-preset noise-reduction power-off mode. This mode controls the vehicle's relays to disconnect and simultaneously outputs audio and video to the vehicle, achieving the same purpose.

[0039] In one optional embodiment, when the monitoring result indicates that there is a user inside the vehicle, or the target mode of the vehicle is the sentry mode enabled, the vehicle can be powered down with noise reduction according to the first mode. When the monitoring result indicates that there is no user inside the vehicle and the target mode is the sentry mode disabled, the vehicle can be powered down with noise reduction according to the second mode.

[0040] Optionally, powering down the vehicle according to the first mode includes: converting the high voltage of the vehicle's power battery to a low voltage; replenishing the vehicle's battery based on the low voltage; and in response to the completion of battery replenishment, controlling the relay in the vehicle's high-voltage power distribution module to disconnect and outputting a target audio to the vehicle.

[0041] The target audio mentioned above can be preset by the user and can reduce electrical noise under high voltage conditions in the vehicle.

[0042] In one optional embodiment, powering down the vehicle according to the first mode includes: firstly, converting the high voltage of the vehicle's power battery to a low voltage; secondly, replenishing the battery with power based on the low voltage; and after the battery is replenished, controlling the relay in the vehicle's high-voltage power distribution module to disconnect and outputting a target audio signal that can reduce the noise of high-voltage power-down to the vehicle, so as to achieve the purpose of noise reduction power-down.

[0043] Optionally, the vehicle status also includes: battery status and power battery status. Before powering down the vehicle according to the first mode, the method further includes: determining whether the battery needs to be recharged based on the battery status; determining whether the power battery is at risk of being depleted based on the power battery status; and powering down the vehicle according to the first mode in response to the battery needing to be recharged and the power battery not being at risk of being depleted.

[0044] The aforementioned battery status may include, but is not limited to: the battery needs recharging, and the battery does not need recharging. The aforementioned power battery status may include, but is not limited to: the power battery is at risk of depletion, and the power battery is not at risk of depletion.

[0045] In an optional embodiment, the vehicle status also includes the battery status and the power battery status. Before powering down the vehicle according to the first mode, it can first be determined whether the battery needs to be recharged and whether the power battery is at risk of being depleted. When the analysis of the battery status determines that the battery needs to be recharged, and the analysis of the power battery status determines that the power battery is not at risk of being depleted, the vehicle can be powered down with noise reduction according to the first mode. The steps of powering down the vehicle with noise reduction according to the first mode are the same as the previous steps, and will not be described in detail here.

[0046] Optionally, in response to the battery not needing to be recharged, or in response to the risk of the power battery being depleted, the vehicle is powered off according to the second mode.

[0047] In one alternative embodiment, before the vehicle is powered down in the first mode for noise reduction, if the battery status analysis determines that the battery does not need to be recharged, or if the power battery status analysis determines that the power battery is at risk of being depleted, then the vehicle can be powered down in the second mode for noise reduction.

[0048] Optionally, the vehicle can be powered down in the second mode, including: controlling the relay in the vehicle's high-voltage power distribution module to disconnect and outputting a target audio signal to the vehicle.

[0049] In one alternative embodiment, powering down the vehicle according to the second mode includes: controlling a relay in the vehicle's high-voltage power distribution module to disconnect and outputting a target audio signal to the vehicle.

[0050] Optionally, the vehicle state also includes: door state and key state. The method further includes: determining whether the door is locked based on the door state; determining whether the key is located within the target area based on the key state; and determining whether the target mode is sentry mode in response to the door being locked or the key being located outside the target area.

[0051] The aforementioned door status may include, but is not limited to: door locked, door unlocked. The aforementioned key status may include, but is not limited to: key within the target area, key outside the target area. The target area may be a pre-defined area centered on the vehicle, and the size of this area can be set by the user according to actual needs; it is not limited in this embodiment.

[0052] In one optional embodiment, the vehicle status also includes the door status and the key status. Therefore, it is possible to determine whether the target mode is the sentry mode based on the door status and the key status. For example, when the door status is analyzed to determine that the door is locked, or when the key status is analyzed to determine that the key is outside the target area, it is possible to determine whether the target mode is the sentry mode.

[0053] Optionally, the method further includes: in response to receiving a power-down command, prohibiting the transmission of work requests to the vehicle's high-voltage load assembly.

[0054] In one alternative embodiment, upon receiving a power-down command, in order to enable the vehicle to successfully power down, the various control units of the vehicle may be prevented from sending operational requests to the vehicle's high-voltage load assembly.

[0055] This invention provides an intelligent noise reduction high-voltage power-off system and control method, mainly comprising: core components including a camera with liveness detection and an audio-visual control unit, a body control unit with smart key recognition, a vehicle control unit, a battery management module, and a high-voltage relay module. System supporting components include a low-voltage battery and sensors, and a door position detection module.

[0056] Based on the intelligent power-off stage of this invention, if the in-vehicle camera's liveness detection determines that all occupants have left the passenger compartment, the system determines whether the driver is still around the vehicle by the location of the smart key, and whether the doors are locked by the door control unit. It also intelligently determines whether the user still needs to get back into the vehicle or requires high-voltage power-on. After locking the vehicle, if the vehicle is in sentry mode, the low-voltage power supply control unit needs to adjust the battery charging strategy and threshold in sentry mode. The vehicle control unit utilizes the intelligent power-off strategy, combining the above information and strategies, to conditionally execute high-voltage power-off after the user leaves the vehicle, effectively avoiding frequent relay operation, effectively reducing the probability of user-perceived noise, and improving the user experience. Figure 2 This is a schematic diagram of an optional intelligent high-voltage power supply system according to an embodiment of the present invention, as shown below. Figure 2 As shown, the system includes: a camera 21, an audio / video control unit 22, a vehicle control unit 23, a door status switch 24, a body control unit 25, a smart key 26, a smart key monitoring unit 27, a battery sensor 28, a low-voltage power supply control unit 29, a battery management module 210, a high-voltage relay module 211, and a battery module 212. The smart key 26 and the smart key monitoring unit 27 can be connected via a wireless network, but are not limited to this.

[0057] The core components include a camera and audio / video control unit with liveness detection, a body control unit with smart key recognition, a vehicle control unit, a battery management module, and a high-voltage relay module. Supporting components include a low-voltage battery and sensors, and the body control unit.

[0058] In one optional embodiment, the camera unit is used to acquire in-vehicle images in real time during the high-voltage power-off phase of the system of the present invention and send them to the audio-visual control unit. The audio-visual control unit is used to receive the in-vehicle images transmitted by the camera unit, determine whether there are vital signs in the images through built-in software, and identify the user's intention to turn the sentry mode on or off. The vital sign detection results and sentry mode requirements are sent to the vehicle control unit via CAN messages. The door status switch is used to detect whether the four doors of the vehicle are locked by switching the switch and transmits the signal to the body control unit via hard wire. The body control unit is used to detect the door lock status via hard wire and send it to the vehicle control unit via CAN messages. The smart key detection unit is used to monitor the Bluetooth signal emitted by the smart key carried by the user in real time, and can determine the distance between the smart key or the user carrying the key and the vehicle through built-in software, and then send it to the vehicle control unit via CAN messages. The low-voltage power control unit collects signals from the vehicle's low-voltage battery sensors and, combined with built-in software, determines whether the battery is low-charged or nearing low-charge. In sentry mode, it automatically adjusts the battery charging strategy and thresholds, then sends a battery charging request to the vehicle control unit via CAN message to recharge the battery. The vehicle control unit employs a new intelligent high-voltage power-down control strategy. It infers the user's intention to enter the passenger compartment based on the smart key location, and determines whether the user intends to use the passenger compartment based on in-vehicle liveness indicators sent by the audio-visual control unit and door status sent by the body control unit. Then, it intelligently determines the timing of high-voltage power-down by combining the battery charging request from the low-voltage power control unit and the sentry mode activation information, and sends the high-voltage power-down request to the battery control module. The power battery pack includes a battery management module, a high-voltage relay module, and battery modules. The battery management module receives high-voltage power-up and power-down requests from the vehicle control unit.

[0059] Figure 3 This is a flowchart of an optional intelligent high-voltage power-off method according to an embodiment of the present invention, such as... Figure 3 As shown, the method includes the following steps:

[0060] Step S31: The driver operates the power-off button to send the user's power-off request to each control unit of the vehicle.

[0061] In step S32, the vehicle control unit sends a shutdown request to all high-voltage load assemblies of the vehicle via CAN message, stopping all high-voltage loads from consuming power and preparing for the high-voltage power-off.

[0062] Step S33: The audio-visual control unit determines whether there are occupants in the vehicle. If there are, proceed to step S34; otherwise, proceed to step S37.

[0063] Step S34: The low-voltage power control unit determines whether the battery needs to be recharged based on the information fed back by the battery sensor, and intelligently adjusts the battery recharge strategy and threshold. If there is a need for recharge, proceed to step S35; otherwise, proceed to step S310.

[0064] Step S35: The vehicle control unit determines whether the continued operation of the low voltage will cause the power battery to run out of power based on the power battery status and power reported by the battery management module. If there is no risk of running out of power, proceed to step S36; if there is a risk of running out of power, proceed to step S310.

[0065] Step S36: The vehicle control unit sends the battery charging request to the DC power converter control unit. The DC power converter control unit converts the high voltage of the power battery to a low voltage and transmits it to the battery, and then proceeds to step S34.

[0066] Step S37: The door control unit determines whether the door is locked. If yes, proceed to step S39; otherwise, proceed to step S38.

[0067] Step S38: The key monitoring unit identifies whether the smart key has entered the effective distance around the vehicle and whether the identity recognition is valid through the wireless radio frequency signal. If it is within the effective range and the maintenance time meets the threshold, proceed to step S37; if it is not within the effective range and the maintenance time meets the threshold, proceed to step S39.

[0068] Step S39: The audio-visual control unit determines whether the user has enabled the sentry mode based on the screen soft switch or the user's remote command. If the sentry mode is enabled, proceed to step S34; if the sentry mode is not enabled, proceed to step S10.

[0069] In step S310, the vehicle control unit integrates several conditions from the upstream steps, such as the vehicle power-down requirement, door locking status, whether there are occupants in the vehicle, and whether the battery needs to be recharged. Through a new intelligent high-voltage power-down control strategy, it makes an intelligent judgment on high-voltage power-down before or after the user leaves the passenger compartment and sends the high-voltage power-down requirement to the battery management module and the audio-visual control unit.

[0070] In step S311, the battery management module receives the high-voltage power-down request sent by the vehicle control unit and drives the relay in the high-voltage power distribution module to disconnect. The audio-visual control unit receives the high-voltage power-down request sent by the vehicle control unit and plays a short background audio (e.g., a few seconds of light music).

[0071] This invention proposes an intelligent noise reduction high-voltage power-off system strategy. After the in-vehicle camera detects that all occupants have left the passenger compartment, the system determines whether the driver is still around the vehicle by the location of the smart key and whether the door is locked by the door control unit. The system intelligently determines whether the user still needs to get in the vehicle or requires high-voltage power-off. By using a new control method and strategy, the system can intelligently determine the user's vehicle usage needs and avoid frequent relay operation.

[0072] This invention also proposes a more intelligent battery charging strategy. When the vehicle is locked and the sentry mode is activated, the low-voltage power control unit needs to adjust the battery charging strategy and threshold under sentry mode. The intelligent power-down strategy is used to achieve a balance between noise reduction requirements and not affecting the user's vehicle usage needs.

[0073] The purpose of this invention is to address the shortcomings of existing technologies by establishing a new intelligent noise reduction and high-voltage power control method for electric vehicles through smart key recognition, camera-based liveness detection inside the vehicle, and a novel control logic. This significantly reduces the chances of passengers perceiving relay sounds, thus improving the user experience. The advantages are as follows:

[0074] 1. When the user operates the key to turn off the power, the camera determines whether there are any occupants in the vehicle as an important prerequisite for high-voltage power-off. The intelligent power-off strategy analyzes and judges the situation, and executes the high-voltage relay action only after all personnel have left the passenger compartment, so as to avoid unnecessary relay action noise from interfering with the user.

[0075] 2. When the user turns off the power using the ignition key, the vehicle needs to determine if the user has activated Sentry Mode. The low-voltage power control unit needs to adjust the battery depletion risk strategy and charging demand threshold. The vehicle control unit comprehensively analyzes the battery power information using an intelligent power-off strategy, and conditionally executes or prohibits high-voltage power-off. From the user's perspective, this achieves a balance between noise reduction and user needs in the high-voltage power-off function.

[0076] 3. When the user operates the key to turn off the door and all occupants leave the vehicle, the entire vehicle needs to collect the door lock status and smart key position to prevent the relay from frequently turning off and then on again and causing noise when the user lingers around the vehicle and still intends to get in. This control method is more intelligent than the existing solutions in the industry.
