Abstract

The invention provides an electric tail gate induction function control method, a vehicle and a storage medium, and the method comprises the steps: determining an authentication region of a vehicle Bluetooth key as a first target region located at the rear side of an electric tail gate under the condition that a user does not have a potential use demand for the electric tail gate; as the first target area is small, the positioning information of the Bluetooth key carried by the user without potential use requirements is not easy to be included, and even if the electric tail door senses strangers or small animals, the electric tail door cannot be triggered to be opened by mistake.

And the positioning information of the vehicle Bluetooth key is easily included in the second target area, so that the reliability of automatic opening of the electric tail door is improved.

Description

Technical Field

[0001] This application relates to the field of vehicle tailgate control technology, and in particular to an electric tailgate sensing function control method, a vehicle, and a storage medium. Background Technology

[0002] With the development of automotive intelligence, electric tailgates have gradually expanded from a highlight feature of mid-to-high-end models to a wider market, becoming an important function for enhancing convenience and luxury. In recent years, contactless sensor-activated tailgate opening technology has gained significant market attention due to its ability to truly "free up" the user's hands, especially in real-world scenarios such as carrying heavy objects or holding items. This is achieved by confirming the user's Bluetooth key is within a target area near the vehicle and sensing the user's specific actions. Users simply need to make a specific gesture below the rear bumper for the tailgate to open automatically, greatly improving the convenience of loading and unloading items.

[0003] However, when the target area is set too large, if the user's Bluetooth key location information is within the target area near the vehicle, and other strangers or animals are detected passing by the power tailgate, the tailgate will automatically open, potentially leading to accidental opening and property damage. Conversely, when the target area is set too small, due to the poor positioning accuracy of the Bluetooth key, if the user is carrying the key within the target area, the location information may shift, causing the key's location information to be outside the target area. In this case, even if the user is detected by the power tailgate, automatic opening will not be possible. Therefore, currently, there is a problem where an unreasonable target area size setting makes it impossible to simultaneously reliably achieve automatic power tailgate opening and prevent accidental opening. Summary of the Invention

[0004] This application provides a method for controlling the sensing function of an electric tailgate, a vehicle, and a storage medium to solve the problem in the prior art that the unreasonable setting of the target area size makes it impossible to simultaneously and reliably achieve automatic opening of the electric tailgate and prevent the tailgate from being opened accidentally.

[0005] In a first aspect, this application provides a method for controlling the sensing function of an electric tailgate, applied to an on-board controller of a vehicle. The vehicle also includes an electric tailgate electrically connected to the on-board controller. The method provided in this application includes: Determine whether the user has a potential need for a power tailgate; If it is determined that the user has no potential need to use the power tailgate, the authentication area of ​​the vehicle's Bluetooth key is determined to be the first target area located behind the power tailgate. If it is determined that the user has a potential need to use the electric tailgate, the authentication area of ​​the vehicle Bluetooth key is determined to be a second target area covering the entire area around the vehicle, wherein the second target area is larger than the first target area. If the location information of the vehicle's Bluetooth key is detected to be within the authentication area of ​​the vehicle's Bluetooth key, the contactless sensing function of the power tailgate will be activated.

[0006] In some implementations, determining whether a user has a potential need for a power tailgate includes: If the vehicle is confirmed to be locked, it is determined that the user has no potential need to use the power tailgate.

[0007] In some implementations, determining whether a user has a potential need for a power tailgate includes: If the vehicle is determined to be unlocked and the location information of the vehicle's Bluetooth key is within a second target area covering the entire area around the vehicle, it is determined that the user has a potential need to use the power tailgate.

[0008] In some implementations, determining whether a user has a potential need for a power tailgate includes: If the vehicle's Bluetooth key location information is not within a second target area covering the entire area around the vehicle, and the Bluetooth signal of the vehicle's Bluetooth key is getting stronger and stronger, and the vehicle's Bluetooth key is receiving an unlocking command, it is determined that the user has a potential need to use the electric tailgate.

[0009] In some implementations, if the location information of the vehicle's Bluetooth key is detected to be within the authentication range of the vehicle's Bluetooth key, the contactless sensing function of the power tailgate is activated, including: If the location information of the vehicle Bluetooth key is detected to be within the authentication area of ​​the vehicle Bluetooth key and remains within a preset first duration, the power tailgate is controlled to activate the contactless sensing function and remain within a preset second duration, wherein the second duration is longer than the first duration.

[0010] In some embodiments, after controlling the power tailgate to activate the contactless sensing function and maintaining it for a preset second duration, the method provided in this application further includes: If the location information of the vehicle Bluetooth key is still detected to be within the authentication area of ​​the vehicle Bluetooth key, the power tailgate will be controlled again to start the contactless sensing function and maintain it for the preset second duration. If the location information of the vehicle's Bluetooth key is detected to be outside the authentication area of ​​the vehicle's Bluetooth key, the contactless sensing function for closing the power tailgate will be controlled.

[0011] In some embodiments, after controlling the power tailgate to activate the contactless sensing function, the method provided in this application further includes: If the Bluetooth signal of the vehicle's Bluetooth key becomes weaker, the contactless sensing function of the power tailgate will be controlled to close.

[0012] In some implementations, determining whether a user has a potential need for a power tailgate includes: If it is determined that the vehicle is not in a driving state and the charging port cover and fuel filler cap are closed, determine whether the user has a potential need to use the power tailgate.

[0013] Secondly, this application also provides a vehicle, including a memory, an on-board controller, and a computer program stored in the memory and executable on the on-board controller, wherein when the on-board controller executes the computer program, the vehicle performs the method provided in the first aspect of this application.

[0014] Thirdly, this application also provides a storage medium storing a computer program, which, when executed by a processor, causes the computer to perform the method provided in the first aspect of this application.

[0015] Fourthly, this application also provides a computer program product, including a computer program that, when run, causes a vehicle to perform the method provided in the first aspect of this application.

[0016] This application provides a method for controlling the sensing function of an electric tailgate, a vehicle, and a storage medium. When it is determined that the user has no potential need to use the electric tailgate, the authentication area of ​​the vehicle's Bluetooth key is determined to be a first target area located behind the electric tailgate. Because the first target area is small, it is unlikely to include the location information of the Bluetooth key carried by a user without potential need for use. Even if the electric tailgate senses a stranger or small animal, the location information of the vehicle's Bluetooth key is not included in the first target area, thus preventing accidental opening of the electric tailgate and ensuring the safety of property inside the vehicle. When it is determined that the user has potential need to use the electric tailgate, indicating that the user is very close to the vehicle, the authentication area of ​​the vehicle's Bluetooth key is determined to be a second target area covering the entire area around the vehicle, wherein the second target area is larger than the first target area. In this way, even if the location of the vehicle's Bluetooth key shifts, the location information of the vehicle's Bluetooth key is easily included in the second target area, improving the reliability of automatic opening of the electric tailgate. Therefore, it can prevent accidental opening of the electric tailgate and improve the reliability of automatic opening of the electric tailgate without increasing hardware costs.

[0022] The technical solutions of this application and how they solve the aforementioned technical problems will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0023] This application provides a method for controlling the sensing function of an electric tailgate, applied to an on-board controller of a vehicle 200. The vehicle 200 also includes an electric tailgate electrically connected to the on-board controller. Figure 1 As shown, the vicinity of vehicle 200 includes a first target area 201 located behind the power tailgate and a second target area 202 covering the entire perimeter of vehicle 200. Figure 2 As shown, the method provided in this application embodiment includes: S201: Determine if the user has a potential need for the electric tailgate. If not, proceed to S202; if yes, proceed to S203.

[0024] Specifically, if it is determined that vehicle 200 is in a locked state, it means that the user has already moved away from vehicle 200, and thus it is determined that the user has no potential need to use the electric tailgate.

[0025] Specifically, if it is determined that the vehicle 200 is unlocked and the location information of the vehicle's Bluetooth key is within the second target area 202 covering the entire area around the vehicle 200, it indicates that the user is near the vehicle 200, and thus it is determined that the user has a potential need to use the electric tailgate.

[0026] Specifically, if the location information of the vehicle Bluetooth key is not within the second target area 202 covering the entire area around the vehicle 200, and the Bluetooth signal of the vehicle Bluetooth key is getting stronger and stronger, and the unlocking command of the vehicle Bluetooth key is received, it indicates that the user is approaching the vehicle 200 and is using the vehicle Bluetooth key to unlock the vehicle 200, thus determining that the user has a potential need to use the electric tailgate.

[0027] Furthermore, S201 can be specifically implemented as follows: when it is determined that the vehicle 200 is not in a driving state and the charging port cover and the fuel filler cap of the vehicle 200 are in a closed state, it can determine whether the user has a potential need to use the electric tailgate, which can improve the reliability of the determination result.

[0028] S202: Determine the authentication area of ​​the vehicle's Bluetooth key as the first target area 201 located behind the power tailgate.

[0029] S203: Determine that the authentication area of ​​the vehicle Bluetooth key is a second target area 202 covering the entire vehicle 200, wherein the second target area 202 is larger than the first target area 201.

[0030] S204: If the location information of the vehicle Bluetooth key is detected to be within the authentication area of ​​the vehicle Bluetooth key, the contactless sensing function of the electric tailgate will be activated.

[0031] Furthermore, if the location information of the vehicle Bluetooth key is detected to be within the authentication area of ​​the vehicle Bluetooth key and remains there for a preset first duration (e.g., 2 seconds), it indicates that the location information of the vehicle Bluetooth key has not been mistakenly drifted to the authentication area of ​​the vehicle Bluetooth key. In this case, the power tailgate is controlled to activate the contactless sensing function and remain there for a preset second duration (e.g., 30 seconds) so that the power tailgate can reliably detect the user and open automatically. It should be noted that the second duration is longer than the first duration.

[0032] It should be noted that the power tailgate is equipped with sensors such as millimeter-wave radar, capacitive sensors, or Time-of-Flight (TOF) infrared sensors. After the power tailgate activates its contactless sensing function, the onboard controller, based on the sensing data collected by the sensors, determines whether a user is detected or the user makes a specified action (such as raising a leg or kicking). In this case, the controller opens the power tailgate.

[0033] In summary, the electric tailgate sensing function control method provided in this application determines the authentication area of ​​the vehicle's Bluetooth key as a first target area 201 located behind the electric tailgate when it is determined that the user has no potential need to use the electric tailgate. Since the first target area 201 is small, it is unlikely to include the location information of the Bluetooth key carried by a user without potential need for use. Even if the electric tailgate senses a stranger or small animal, the location information of the vehicle's Bluetooth key is not included in the first target area 201, thus preventing accidental opening of the electric tailgate and ensuring the safety of property inside the vehicle. When it is determined that the user has potential need to use the electric tailgate, indicating that the user is very close to the vehicle 200, the authentication area of ​​the vehicle's Bluetooth key is determined as a second target area 202 covering the entire area around the vehicle 200, wherein the second target area 202 is larger than the first target area 201. In this way, even if the location of the vehicle's Bluetooth key shifts, the location information of the vehicle's Bluetooth key is easily included in the second target area 202, improving the reliability of automatic opening of the electric tailgate. Therefore, it can prevent accidental opening of the electric tailgate and improve the reliability of automatic opening of the electric tailgate, without increasing the hardware cost.

[0034] Following the above-described S204, the method provided in this application embodiment may further include: if the location information of the vehicle Bluetooth key is detected to still be within the authentication area of ​​the vehicle Bluetooth key, then the electric tailgate is controlled to activate the contactless sensing function again and maintain it for a preset second duration; if the location information of the vehicle Bluetooth key is detected to be no longer within the authentication area of ​​the vehicle Bluetooth key, indicating that the user has left the authentication area, then the electric tailgate is controlled to deactivate the contactless sensing function. This prevents the electric tailgate from being mistakenly opened by a stranger or small animal.

[0035] In addition, after S204 above, the method provided in this application embodiment may further include: if the Bluetooth signal of the vehicle Bluetooth key is detected to be getting weaker and weaker, it indicates that the user is moving away from the vehicle 200 and there is no longer a potential need to open the electric tailgate, and the contactless sensing function of the electric tailgate is turned off. In this way, the electric tailgate can be prevented from being accidentally opened by strangers or small animals.
