Description

Technical Field

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

[0002] With the rapid development of science and technology, UWB technology has been increasingly used in smart cars. UWB stands for UltraWideband, which is a carrier-free communication technology. By using UWB's precise ranging capability, you can combine multiple anchor points arranged on the vehicle with legal digital keys or mobile phones by simply approaching the vehicle to achieve precise spatial perception of the vehicle at close range. Using vehicle spatial perception, the vehicle can independently judge and control the vehicle to achieve intelligent control. By deploying UWB anchor points at the rear tailgate of the car, the position of the digital key can be accurately located, and by detecting the user's leg movements, the operation of opening and closing the tailgate of the car can be realized. Now there are many ways to control the tailgate of the car, such as mobile phone apps, fob key buttons, etc., but if the user's hands are full of things and cannot free their hands to operate, the above methods are not very friendly.

[0003] However, if the digital key device is required to be in a positioning and detection state all the time to detect whether it has entered the corresponding functional area, the power of a digital key device such as a fob key will be exhausted quickly. If the vehicle is required to be in a detection state at the anchor point all the time, the power consumption of the entire vehicle will also be unacceptable.

[0004] The above contents are only used to assist in understanding the technical solution of the present application and do not constitute an admission that the above contents are prior art. Summary of the invention

[0045] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0046] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0047] The main solution of the embodiment of the present application is to use a UWB (Ultra Wideband) digital key to achieve contactless control of the car tailgate. This solution aims to solve the problem that the existing car tailgate control method is inconvenient to operate when the user is carrying heavy objects. By deploying a UWB anchor point at the tailgate and combining it with the user's leg movement detection, the tailgate can be automatically opened and closed, thereby improving the user experience. The core of the solution is to introduce the concept of UWB detection state, including four states: OFF, Standby, Active and Detection. In the Standby state, although the UWB anchor point is turned on, no kick detection is performed. When the user approaches the vehicle with a valid digital key, the UWB system will switch to the Active state and start detecting kicking actions. Only when the kicking action is effectively detected and the digital key is within the preset effective area, the UWB system will enter the Detection state and send a request for the kick to trigger the tailgate to open or close.

[0048] The design of the solution takes into account a variety of application scenarios, such as the user approaching the vehicle with a Bluetooth key, the needs after parking, the needs after driving, and the possible need to re-control the tailgate after the tailgate status changes, ensuring that the tailgate can be intelligently controlled when the user really needs it. In addition, the technical briefing also defines the effective kicking action and the kicking action detection range and the digital key positioning range. These parameters can be calibrated by the developer according to the actual hardware capabilities. This solution reduces the complexity of user operations through the intelligent UWB system, and also reduces the energy consumption of the digital key and the vehicle, realizing a high-efficiency, low-false-touch car tailgate control function.

[0049] In the prior art, smart cars have adopted a variety of methods to control the tailgate, such as through mobile phone applications or buttons on the Fob key. These methods are convenient to operate when the user's hands are free, but they become less friendly when the user is carrying items, requiring the user to free up his hands to operate, which causes a certain degree of inconvenience in actual use.

[0050] The main problem faced by the existing technology is that when the user's hands are occupied, the convenience of the existing control method is greatly reduced. In addition, when the existing technology realizes the automatic opening and closing function of the car tailgate, it usually requires the digital key or device to be in a continuously positioned state, which will not only quickly consume the power of the digital key device, but also increase the power consumption of the entire vehicle, thereby affecting the vehicle's energy efficiency and user experience. These problems expose the limitations of existing technologies in terms of intelligence and user convenience. It is these defects that have given rise to the demand for more efficient, low-energy and user-friendly tailgate control solutions.

[0051] The present application provides a solution, which enters a detection standby state in response to the activation of an ultra-wideband (UWB) detection anchor point preset for the rear tailgate of the vehicle; enters a detection active state from the detection standby state in response to a valid detection trigger event; in the detection active state, performs a kicking action detection based on the UWB detection anchor point to obtain a kicking action detection result; and controls the opening and closing of the rear tailgate of the vehicle based on the kicking action detection result. By controlling the state of the UWB detection anchor point through the above-mentioned scheme, the kicking action is detected to control the rear tailgate of the vehicle, thereby reducing the power consumption of the entire vehicle while ensuring the accuracy of kicking detection and recognition.

[0052] It should be noted that the execution subject of this embodiment can be a computing service device with vehicle control, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a vehicle control system, etc. The following takes the vehicle control system as an example to illustrate this embodiment and the following embodiments.

[0053] Based on this, the embodiment of the present application provides a vehicle control method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the vehicle control method of the present application.

[0054] In this embodiment, the vehicle control method includes steps S1000 to S4000:

[0055] Step S1000: In response to the activation of the ultra-wideband (UWB) detection anchor point preset at the rear tailgate of the vehicle, entering a detection standby state;

[0056] It should be noted that in this embodiment, in order to realize functions such as contactless entry into the vehicle through the digital key, several UWB anchor points are deployed in advance on the vehicle body. This solution is to reuse the UWB anchor point at the tailgate, detect the user's leg movements, locate the position of the digital key, and control the tailgate of the car, so as to realize more functions at the lowest cost and improve the user experience.

[0057] However, if the digital key device is required to be in a positioning state all the time to detect whether it has entered the corresponding functional area, the power of the digital key device, such as a fob key, will be exhausted quickly. If the vehicle and the digital key device are required to keep the anchor point in the detection state once the Bluetooth connection is successful, the power consumption of the entire vehicle is unacceptable. Figure 2 , Figure 2This is the UWB foot-controlled tailgate detection state transition diagram of the vehicle control method of the present application. The UWB detection anchor point preset at the rear tailgate of the vehicle does not enter the detection state immediately after being started. Instead, after the system detects that the UWB detection anchor point preset at the rear tailgate of the vehicle is started, it enters the detection standby state standby. In the detection standby state, the UWB anchor point will not perform actions such as foot kick detection and digital key signal range area detection that consume more power, but waits for other user actions to trigger corresponding events, so that the system controls the UWB anchor point to enter the detection active state from the detection standby state before performing detection. In this way, the detection state of the UWB detection anchor point is flexibly controlled, thereby maintaining power consumption at a lower level and reducing energy consumption compared to the prior art.

[0058] Step S2000: In response to a valid detection triggering event, entering a detection active state from the detection standby state;

[0059] It should be noted that in this embodiment, after the system starts the UWB detection anchor point, it does not immediately start its detection state, but enters the standby state and remains silent, waiting for the system to trigger an effective detection trigger event, and then enters the detection active state from the detection standby state to detect the kicking behavior and further control the vehicle's tailgate. It should be noted that the effective detection trigger event may be triggered by a variety of situations, such as after the digital key establishes a Bluetooth connection with the vehicle, the vehicle changes from a moving state to a stationary state, or the vehicle's door is opened, etc., which can be judged separately or in combination.

[0060] Step S3000: In the detection activity state, performing kicking action detection based on the UWB detection anchor point to obtain a kicking action detection result;

[0061] It should be noted that when the system is in the detection activity state, the UWB anchor point at the rear tailgate of the vehicle in this embodiment will begin to perform its core function - kicking action detection. Specifically, it can be carried out by real-time monitoring of the actions in the target area and judging whether the actions meet the definition of kicking actions according to preset standards.

[0062] In addition, it should be noted that the effectiveness judgment criteria of the kicking action can be preset and modified, and these criteria may include the speed, amplitude and duration of the action, etc. In this way, the system can distinguish between a true kicking action and a false trigger or unauthorized action triggering function execution mechanism, thereby avoiding unnecessary or unsafe opening and closing of the tailgate.

[0063] For example, in a specific embodiment, the system will identify the kicking action within the preset target detection area in the detection activity state, and determine whether it is a valid kicking action according to the kicking action specification. If the action meets the standard, the system will record the kicking action as valid, so as to perform the next step of tailgate control.

[0064] Step S4000: Controlling the opening and closing of the tailgate based on the kicking action detection result.

[0065] It should be noted that, in this embodiment, the system will determine whether to generate a kick trigger request based on the kick action detection result, and then control the opening and closing of the tailgate.

[0066] Additionally, it should be noted that before executing this step, the system can also perform other auxiliary detections to jointly determine whether to generate a control request or control instruction, such as confirming whether the digital key is within the valid connection range. More specifically, only when the UWB is in the kick detection state, a valid kick action is detected within the defined kick range, and then the valid digital key is located in the calibrated key area, is the foot-kick control of the tailgate considered to be successfully triggered. If any of the above conditions is not met, the foot-kick control tailgate function cannot be triggered, thereby reducing the probability of a user's accidental touch being successfully identified. This is a safety measure to ensure that the control instructions for the tailgate are executed with the authorization of the owner.

[0067] For example, in a specific implementation, if the kicking action is detected as valid and the digital key is within the preset valid connection range, the system will generate a kick trigger request and execute this request through the vehicle's rear tailgate execution end to achieve automatic opening and closing of the tailgate, providing convenience for the car owner.

[0068] In a feasible implementation manner, step S1000 may include step A1000:

[0069] Step A1000: When it is detected that the digital key is within a preset effective connection range, a Bluetooth connection request is initiated to the digital key and a Bluetooth connection is established;

[0070] Step S4000 may include step A4000: controlling the opening and closing of the tailgate according to the kicking action detection result and the effective connection range of the digital key.

[0071] It should be noted that this vehicle control method is an intelligent solution that aims to improve the convenience and safety of users when using smart cars, while reducing the power consumption of each participating link and increasing the endurance of the vehicle and digital key. This embodiment uses ultra-wideband UWB technology to achieve precise control of the vehicle's tailgate, and combines Bluetooth technology to communicate with the digital key to ensure the legality and accuracy of the operation.

[0072] First, when the system detects that the digital key has entered the preset effective connection range, it will automatically initiate a Bluetooth connection request to establish a stable connection with the digital key. This step is the basis for ensuring that subsequent operations can be performed safely and is also the key link to achieve seamless connection between the vehicle and the user.

[0073] Next, the system responds to the activation of the UWB detection anchor and enters the detection standby state. In this state, the system is in standby mode, ready to respond to the user's kicking action or other valid detection trigger events at any time. When the system detects these trigger events, it will change from the standby state to the detection active state and begin to accurately detect the kicking action.

[0074] In the detection activity state, the system identifies the kicking action within the preset target detection area based on the UWB detection anchor point, and judges the effectiveness of the action according to the preset kicking action specification. This step is the core of realizing intelligent control, ensuring that the system will only respond when the user performs the correct kicking action.

[0075] In addition, it should be noted that the validity of the kicking action and the effective connection range of the digital key jointly determine the opening and closing of the vehicle's tailgate. If the kicking action is detected as valid and the digital key is within the effective connection range, the system will generate a kicking trigger request, which will be executed by the vehicle's tailgate execution end to achieve automatic opening and closing of the tailgate.

[0076] In addition, the duration of the detection activity state is variable, and the system will adjust it according to the vehicle state and user behavior. For example, when the vehicle enters the moving state from a stationary state, or the vehicle enters the sleep mode and the Bluetooth connection is disconnected, the system will trigger the detection standby trigger event and return to the detection standby state to reduce unnecessary energy consumption and misoperation.

[0077] For example, in one feasible implementation, the owner brings the digital key close to the vehicle, and the system first establishes a connection with the key via Bluetooth. Subsequently, when the owner kicks the vehicle within the UWB detection area of ​​the tailgate, the system determines the validity of the action and triggers the automatic opening and closing of the tailgate after confirming that the digital key is still within the effective connection range. If the vehicle starts to move or the owner leaves the vehicle, the system automatically returns to standby mode and waits for the next effective trigger event. This entire process realizes the intelligent control of the vehicle's tailgate, improves the user experience, and also ensures the safety and accuracy of the operation.

[0078] In a feasible implementation manner, before step S2000, steps S1100 to S1200 may be included:

[0079] Step S1100: If a Bluetooth connection is established with the digital key in the sleep mode, triggering the valid detection trigger event;

[0080] Step S1200: If, while the Bluetooth connection is valid, it is detected that the vehicle changes from a moving state to a stationary state, and the door of the vehicle is opened, the valid detection trigger event is triggered.

[0081] It should be noted that, in this embodiment, referring to Figure 2 When the vehicle is in sleep mode and parked in the parking lot, a user approaches the vehicle with a valid Bluetooth key. At this time, the user may need to open the tailgate and kick it. Therefore, when the user approaches the vehicle and the digital key is successfully connected to the vehicle via Bluetooth, the system will trigger a valid detection trigger event, thereby activating the vehicle's detection system.

[0082] In addition, it should be noted that when the vehicle changes from a moving state to a stationary state and detects that the door is opened, an effective detection trigger event will also be triggered. For example, when the user drives to the side of the road, the vehicle and the digital key device are still connected via Bluetooth, and the passenger or rear seat may need to open the door and then open the tailgate. At this time, an effective detection trigger event is triggered, and the system controls the UWB detection anchor point to enter the detection activity state and maintain the UWB kick detection. Or, for example, when the user finishes driving and opens the driver's door, the user may need to open the tailgate. Therefore, when the Bluetooth connection is not disconnected, an effective detection trigger event is triggered, and the system controls the UWB detection anchor point to enter the detection activity state and maintain the UWB kick detection for x minutes. This mechanism enables the vehicle to intelligently identify scenarios where the user may need to use the tailgate, such as picking up and placing items after parking, so as to prepare in advance.

[0083] In the detection standby state, the system will remain ready to detect the kicking action. Once a valid detection trigger event is received, the system will immediately enter the detection active state. In this state, the system recognizes the kicking action within the preset target detection area based on the UWB detection anchor point, and determines the validity of the kicking action according to the preset specifications.

[0084] In addition, it should be noted that the effectiveness of the kick action and the effective connection range of the digital key jointly determine the opening and closing operation of the tailgate. Only when the kick action is confirmed to be effective and the digital key is within the effective connection range, the system will generate a kick trigger request. This request will be sent to the vehicle's rear tailgate execution end, which will execute the tailgate opening and closing action.

[0085] To further optimize the user experience and reduce unnecessary energy consumption, the duration of the detection activity state is set to a preset variable value. When the vehicle enters the motion state from the stationary state, or the vehicle enters the sleep mode and the Bluetooth connection is disconnected, or the duration of the detection activity state reaches the preset time threshold, the system will trigger the detection standby trigger event and return to the detection standby state.

[0086] For example, in one feasible implementation, when the owner brings the digital key close to a vehicle in sleep mode, the vehicle will automatically establish a Bluetooth connection with the key and intelligently determine whether the tailgate control system needs to be activated based on the door opening and closing status or the vehicle's motion status. Once the system is activated, the UWB detection anchor point will monitor the kicking action in real time to ensure that the tailgate is only triggered when the owner makes the correct action. If the vehicle starts to move or the owner leaves, the system will automatically enter an energy-saving standby state, waiting for the next effective operation. This overall solution not only improves the convenience of operation, but also ensures the safety and energy efficiency of the system.

[0087] The present embodiment provides a vehicle control method, which enters a detection standby state in response to the activation of an ultra-wideband (UWB) detection anchor point preset for the vehicle's tailgate; enters a detection active state from the detection standby state in response to a valid detection trigger event; in the detection active state, performs a kicking action detection based on the UWB detection anchor point to obtain a kicking action detection result; controls the vehicle's tailgate to open and close based on the kicking action detection result. The state of the UWB detection anchor point is controlled by the above scheme to detect the kicking action and thus control the vehicle's tailgate, thereby reducing the power consumption of the entire vehicle while ensuring the accuracy of kicking detection and recognition.

[0088] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 3 , step S3000 of the vehicle control method further includes steps S3100 to S3200:

[0089] Step S3100: in the detection activity state, identifying a kicking action in a preset target detection area based on the UWB detection anchor point;

[0090] It should be noted that the UWB detection anchor point is a key component in this embodiment, which uses ultra-wideband technology for precise spatial positioning and motion capture. In the detection activity state, the system will use these anchor points to monitor any action in the preset target detection area, especially the user's kicking action, and by capturing the user's body movements intended to interact with the vehicle, intelligent control without manual operation can be achieved.

[0091] In addition, it should be noted that the preset target detection area is a spatial range near the rear tailgate of a vehicle pre-set by the system. The system will only recognize and respond to kicking actions within this area, so that the power consumption of the control system is not too high while ensuring the accuracy and efficiency of recognition. This helps to avoid false triggering and ensures that the kicking action will only be recognized and processed by the system when the user is close to a specific area of ​​the vehicle.

[0092] For example, in a specific implementation, when the system detects that a user has entered the vehicle's preset detection area with a digital key, and the vehicle has established a connection with the key via Bluetooth, the system will automatically enter the detection activity state. At this time, if the user kicks in the preset target detection area near the tailgate, the UWB detection anchor will capture this action and treat it as a possible control instruction for the next step.

[0093] Step S3200: determining whether the kicking action is a valid kicking action according to a preset kicking action specification, and obtaining a kicking action detection result.

[0094] It should be noted that in this embodiment, after the kicking action is recognized, the system will determine whether the action is a valid control instruction according to the preset kicking action specification. This step is a key link to ensure the accuracy and reliability of the system response. By defining what kind of kicking action will be recognized as valid through clear specifications, it can avoid misoperation caused by random actions.

[0095] In addition, it should be noted that the definition of an effective kicking action may include characteristics of multiple dimensions such as the speed, strength, and duration of the action. The system compares these characteristics with the preset specifications to determine the effectiveness of the action. For details, please refer to Figure 4 , Figure 4 This is a schematic diagram of the effective kicking action specification for the vehicle control method of this application. If the force of the action is too small or the duration is too short, etc., it may not be recognized as a valid action.

[0096] For example, in a specific implementation, after the system captures the user's kicking action in the detection activity state, it will immediately analyze whether the action meets the preset kicking action specifications. If the action meets the specifications, such as moderate force, appropriate speed, and sufficient duration, the system will determine that the kicking action is valid and prepare to generate a kick trigger request to control the opening and closing of the vehicle's rear tailgate. This design not only improves the convenience of operation, but also ensures the accuracy of operation and the safety of the vehicle.

[0097] In a feasible implementation manner, the kicking action detection result includes a kicking action being valid and a kicking action being invalid, and step S4000 may include steps S4100 to S4200:

[0098] Step S4100: If the kicking action detection result is that the kicking action is valid, then detecting whether the digital key is within a preset valid connection range;

[0099] Step S4200: If the digital key is within the effective connection range, the vehicle tailgate is controlled to open and close.

[0100] It should be noted that the kicking action detection result in this solution is crucial for the intelligent control of the vehicle's tailgate. When the system detects a valid kicking action, a series of related logical judgments and operation processes will be triggered to ensure that the opening and closing of the tailgate is both safe and meets the actual needs of users.

[0101] First, the system will confirm whether the kicking action is valid. This judgment is based on the preset kicking action specifications, such as the strength, speed, and duration of the action. If the kicking action meets these specifications, the system will consider it valid and proceed to the next step.

[0102] In addition, it should be noted that if the kicking action is determined to be valid, the system will immediately check whether the digital key is within the preset valid connection range. This step is to ensure the safety and legality of the tailgate operation and prevent unauthorized users from triggering the opening and closing of the tailgate. In this way, when the UWB is in the kicking detection state, a valid kicking action is detected within the defined kicking range, and then the valid digital key is located in the calibrated key area, and the foot-kick control tailgate is considered to be successfully triggered. If any of the above conditions is not met, the foot-kick control tailgate function cannot be triggered, the probability of false touch is low, and neither the digital key power nor the vehicle power consumption will be too large, and the user experience is better.

[0103] If the digital key is confirmed to be within the valid connection range, the system will generate a kick trigger request. This request is a direct instruction for the tailgate opening and closing operation, which will be sent to the vehicle's rear tailgate actuator.

[0104] Finally, the tailgate actuator converts the received kick trigger request into actual action and controls the tailgate to open and close. This process realizes true contactless operation, greatly improves the user experience, and reduces the inconvenience of not being able to open and close the tailgate manually due to holding objects.

[0105] For example, in a feasible implementation, when a user approaches a vehicle with a digital key and performs a standard kicking motion, the UWB detection anchor point will capture the motion, and the system will then determine the validity of the motion. After confirming that the motion is valid, the system checks the location of the digital key. If the key is also within the valid range, the system generates a kick trigger request. Subsequently, the tailgate execution end receives the request and executes it, realizing the automatic opening and closing of the tailgate. The entire process does not require manual operation by the user, providing a convenient and intelligent vehicle tailgate control solution.

[0106] In a feasible implementation manner, step S2000 may include steps B1000 to B2000:

[0107] Step B1000: If at least one of the preset trigger conditions is met, a detection standby trigger event is triggered, wherein the preset trigger conditions include: the vehicle enters a moving state from a stationary state, the vehicle enters a sleep mode and the Bluetooth connection is disconnected, and the duration of the detection activity state reaches a preset time threshold;

[0108] Step B2000: In response to the detection standby triggering event, entering the detection standby state from the detection active state.

[0109] It should be noted that the vehicle control method in this solution realizes precise control of the vehicle's rear tailgate through a series of intelligent detection and response mechanisms. In this embodiment, in order to reduce the power consumption of the entire vehicle while ensuring the accuracy of kick detection and recognition, a conversion logic from the detection active state to the detection standby state is specially designed to adapt to different usage scenarios and vehicle states, to ensure the efficient operation of the system and the effective use of energy. Specifically, in order to optimize the efficiency and responsiveness of the vehicle's tailgate control system, a comprehensive trigger mechanism is introduced, allowing the system to switch from the detection active state to the detection standby state when any preset condition is met. More specifically, the preset trigger conditions include changes in vehicle status, monitoring of system time, and the status of Bluetooth connection. For example, when the vehicle changes from a stationary state to a moving state, it usually means that the user has completed the operation of the tailgate and is ready to drive the vehicle. At this time, switching to the standby state can reduce unnecessary energy consumption and wait for the next operation instruction.

[0110] First, if the vehicle changes from a stationary state to a moving state, the system recognizes this change as a detection standby trigger event. This design takes into account that the user may no longer need to operate the tailgate after the vehicle is started, so the system automatically enters the standby state to reduce unnecessary energy consumption and misoperation.

[0111] In addition, it should be noted that when the vehicle enters sleep mode and the Bluetooth connection with the digital key is disconnected, the detection standby trigger event will also be triggered. This trigger condition is applicable when the user leaves the vehicle or the vehicle has not been used for a long time. In this way, the system enters a low-energy state and waits for the next effective trigger.

[0112] In addition, the system also sets a duration threshold for detecting active states. When the duration of the detection active state reaches this preset time threshold, the detection standby trigger event will also be triggered. This design can prevent the system from being in active state for a long time, thereby reducing energy consumption, and at the same time ensure that the system can automatically return to standby state when the user does not perform any operation.

[0113] Finally, in response to the detection standby trigger event, the system will transition from the detection active state to the detection standby state. This transition is smooth and seamless, ensuring the correctness of the system state and the timeliness of the response.

[0114] For example, in a feasible implementation, when the user completes the operation of using the tailgate of the vehicle and leaves the vehicle, the vehicle's UWB detection anchor point and Bluetooth system will work together to automatically monitor the status of the vehicle and the digital key. If the vehicle starts to move or the digital key carried by the user leaves the effective connection range, the system will automatically switch to standby mode to wait for the next user operation request. This intelligent control process not only improves the user experience, but also optimizes the vehicle's energy management.
