[0002] With the continuous development of economy and vehicle technology, vehicles have become the first choice for people's daily travel. However, there are many types of vehicles with different levels of intelligence. The intelligence and convenience of using the rear doors of vehicles have gradually become the standards for people to buy vehicles.

[0003] In the related art, the user can open the back door through the back door switch on the smart key or the back door handle, or through the foot switch. For example, the user can use the foot to perform actions, convert the foot actions into an opening signal and transmit it to the back door controller, thereby opening the back door.

Therefore, the problem that the user's extra actions are added, the convenience of vehicle use is reduced, the cost of buying a car is increased, the user's satisfaction is reduced, and the intelligence and feasibility of the vehicle are poor is solved in the related technology.

[0040] Specifically, Figure 1 The present invention is a flowchart of a method for controlling a vehicle tailgate provided according to an embodiment of the present application.

[0041] like Figure 1 As shown, the control method of the vehicle back door, the rear part and the rear bumper of the vehicle are provided with a plurality of ultrasonic sensors, wherein the method comprises the following steps:

[0042] In step S101, first user data collected by at least one sensor among a plurality of ultrasonic sensors is acquired.

[0043] It can be understood that the ultrasonic sensor in the embodiment of the present application can calculate the distance between the sensor and the object through the time difference between the transmitted wave and the received wave.

[0044] In addition, the multiple sensors are at least two sensors, such as two sensors, three sensors, four sensors, etc., which can be set at the rear of the vehicle and the rear bumper. The specific settings can be made by technicians in this field according to actual conditions, and this application does not make any specific restrictions.

[0045] In some embodiments, the embodiments of the present application can collect the first user data of the user through at least one sensor among the multiple sensors installed at the rear of the vehicle and the rear bumper. The first user data can be user data collected based on at least one sensor, which can be but not limited to: the distance between the user and the vehicle; the relationship between the user's travel direction and the vehicle position, such as: approaching, leaving, etc.; the user's travel speed, acceleration, etc.; this application does not make specific restrictions.

[0046] In addition, the at least one sensor may be one sensor, two sensors or another number of sensors, which may be specifically configured by a person skilled in the art according to actual conditions, and this application does not impose any specific limitation thereto.

[0047] For example, when a user approaches the tailgate of a vehicle from the rear of the vehicle, at least one ultrasonic sensor among multiple ultrasonic sensors will detect the user's first user data, such as speed, distance, direction, etc. This application does not make specific restrictions. When the user stays at the tailgate, the ultrasonic sensor will continue to collect the user's first user data.

[0048] In step S102, a first position movement state of a user is identified based on the first user data, and it is determined whether the first position movement state meets a preset activation condition.

[0049] It can be understood that the embodiments of the present application can use the first user data to determine the user's first position movement status, such as movement speed, movement distance, movement direction, etc., which can be specifically set by technical personnel in this field according to actual conditions, and this application does not make specific restrictions.

[0050] As a possible implementation method, the embodiment of the present application can identify the user's first location movement state based on the first user data, and then determine whether the first location movement state meets certain activation conditions, wherein the certain activation conditions can be set by technical personnel in this field according to actual conditions, and this application does not make specific restrictions.

[0051] For example, the embodiment of the present application can obtain the user's first position movement state through the first user data, such as whether the user is approaching the vehicle from far to near or leaving the vehicle from near to far from the rear of the vehicle. When the user stays at the rear door, the ultrasonic sensor will continue to detect the user's movement distance and determine in real time whether the first position movement state meets certain activation conditions.

[0052] Optionally, in one embodiment of the present application, identifying the first position movement state of the user based on the first user data includes: extracting the distance characteristics of the user at each moment according to the first user data; and determining whether the first position movement state is an approaching state or a leaving state according to the distance characteristics at each moment.

[0053] It can be understood that the distance feature can be the distance feature between the user and the vehicle, which can be a specific numerical value or a relative value of the distance change. It can be specifically set by technicians in this field according to actual conditions, and this application does not make any specific restrictions.

[0054] It will be understood by those skilled in the art that the embodiments of the present application can extract the distance characteristics of the user at each moment based on the first user data, and then determine the first position movement state based on the distance characteristics, which can be but is not limited to an approaching state or a leaving state, and the present application does not impose any specific limitations.

[0055] For example, the embodiment of the present application can obtain the distance characteristics of the user at the current moment, the distance characteristics at the previous moment, and the distance characteristics at the next moment based on the first user data, and then use the distance characteristics of these three moments to determine the first position movement state. If the distance between the user and the rear of the vehicle at the previous moment, the current moment, and the next moment is getting smaller and smaller, it means that the user is slowly approaching the vehicle, and the first position movement state is the approaching state; conversely, if the distance between the user and the rear of the vehicle is getting larger and larger, it means that the user is slowly leaving the vehicle, and the first position movement state is the leaving state.

[0056] In step S103, if the first position movement state satisfies the preset opening condition and the distance between the user and the vehicle is less than the preset distance for a duration greater than the preset duration, the back door of the vehicle is opened.

[0057] In some embodiments, the embodiment of the present application opens the vehicle's tailgate when the first position moving state satisfies certain opening conditions and the distance between the user and the vehicle is less than a certain distance for a period longer than a certain period.

[0058] Among them, the certain distance and the certain duration can be set by technicians in this field according to actual conditions, and this application does not impose any specific restrictions.

[0059] For example, the embodiment of the present application can detect the distance between the user and the vehicle in real time when the first position moving state is the approaching state, and determine whether the distance between the user and the vehicle is less than a certain distance, such as 50 centimeters. Then, when the distance between the user and the vehicle is less than 50 centimeters, determine whether the duration is greater than a certain duration, such as 5 seconds, and allow the vehicle to open the back door.

[0060] Optionally, in one embodiment of the present application, before opening the tailgate of the vehicle, it also includes: detecting the actual distance between the vehicle key and the vehicle; and allowing the tailgate to be opened when it is detected that the actual distance is less than a preset safety distance.

[0061] It should be noted that in order to prevent other users from approaching the vehicle to unlock the rear door, the embodiment of the present application can also detect the position of the vehicle key in real time.

[0062] That is to say, before opening the back door of the vehicle, the embodiment of the present application can also detect the actual distance between the vehicle key and the vehicle in real time, and allow the vehicle to open the back door if the actual distance is less than a certain safety distance. The certain safety distance can be set by a person skilled in the art according to actual conditions, and this application does not impose any specific limitation.

[0063] For example, user A and user B approach the vehicle one after another, and user A does not carry the vehicle key, while user B carries the vehicle key. When user A approaches the vehicle and meets the conditions for opening the vehicle's back door, user A is not allowed to open the vehicle's back door because user A does not carry the vehicle key. On the contrary, when user B slowly approaches the rear of the vehicle, the first position movement state meets certain opening conditions, and the distance between the user and the vehicle is less than a certain distance for a period of time greater than a certain period, the vehicle's back door can be opened.

[0064] Optionally, in one embodiment of the present application, before opening the tailgate of the vehicle, it also includes: determining whether the vehicle is in the tailgate automatic opening mode; if the vehicle is in the tailgate automatic opening mode, allowing the tailgate to be opened.

[0065] It will be understood by those skilled in the art that the automatic tailgate mode in the embodiment of the present application can be a function embedded in the vehicle, and the user can set whether this function is turned on or not according to the actual situation. It can be set by the vehicle key, or by the vehicle control panel, or by real-time operation using a mobile phone application. The specific setting can be made by those skilled in the art according to the actual situation, and the present application does not impose any specific restrictions.

[0066] In some embodiments, the embodiments of the present application can determine whether the vehicle is in the automatic tailgate opening mode before opening the tailgate of the vehicle. If the vehicle is in the automatic tailgate opening mode, the vehicle can be allowed to open the tailgate.

[0067] For example, before shopping in a supermarket, user A sets vehicle A to automatic back door opening mode through a mobile phone application. Then, when user A finishes shopping and approaches the vehicle to drive away, the back door of the vehicle can be automatically opened, reducing the difficulty for user A to open the back door.

[0068] In order to prevent other users from mistakenly opening the back door of vehicle B by mistake, user B turns off the back door automatic mode, so that vehicle B is in the back door automatic closing mode. Then, even if user B meets the requirements to open the back door of vehicle B, the back door of vehicle B is not allowed to open automatically.

[0069] Optionally, in one embodiment of the present application, after opening the tailgate of the vehicle, it also includes: acquiring second user data collected by at least one sensor among multiple ultrasonic sensors; identifying the user's second position movement state based on the second user data, and determining whether the second position movement state meets the preset closing condition; if the second position movement state meets the preset closing condition, closing the tailgate of the vehicle.

[0070] Among them, in the embodiment of the present application, the second user data can be but is not limited to the distance, speed, acceleration, etc. between the user and the vehicle, which can be specifically set by technicians in this field according to actual conditions, and this application does not make any specific restrictions.

[0071] The second position movement state may be, but is not limited to, a leaving state, a stationary state, etc., and this application does not impose any specific limitation.

[0072] As a possible implementation method, the embodiment of the present application can collect the second user data of the user according to at least one sensor among the multiple ultrasonic sensors, and use the second user data to determine the second position movement state of the user, and then determine whether the second position movement state meets a certain closing condition, and close the back door of the vehicle when the second position movement state meets the certain closing condition. Among them, the certain closing condition can be set by a person skilled in the art according to actual conditions, and this application does not impose specific restrictions.

[0073] For example, user A, user B, and user C are riding in the same vehicle A. If, after allowing the tailgate to be opened, vehicle A detects that the second position movement states of user A, user B, and user C meet certain closing conditions, the tailgate of the vehicle will be closed.

[0074] The working principle of the vehicle tailgate control method proposed in the embodiment of the present application is described in detail below with reference to a specific embodiment.

[0075] in, Figure 2 The present invention is a flowchart of the working principle of a vehicle tailgate control method provided according to an embodiment of the present application.

[0076] Step S201: Setting a plurality of ultrasonic sensors.

[0077] It can be understood that the embodiment of the present application can be equipped with multiple ultrasonic sensors at the rear of the vehicle and the rear bumper, such as ultrasonic sensor 1, ultrasonic sensor 2, ultrasonic sensor 3 and ultrasonic sensor 4, and use these four ultrasonic sensors to collect the user's first user data and second user data.

[0078] Among them, the embodiment of the present application can extract the distance characteristics of the user at each moment through the first user data, and then obtain the user's first position movement state, and when the first position movement state is a close state, detect the distance between the user and the vehicle in real time, and judge whether the distance between the user and the vehicle is less than a certain distance, such as 50 centimeters, and then when the distance between the user and the vehicle is less than 50 centimeters, judge whether the duration is greater than a certain duration, such as 5 seconds, and then allow the vehicle to open the back door.

[0079] The second user data may be used to determine the second position movement state of the user, and to close the rear door of the vehicle when the second position movement state satisfies a certain closing condition.

[0080] Step S202: The back door control unit operates based on the vehicle key and the back door motor.

[0081] That is to say, in order to prevent other users from approaching the vehicle to unlock the back door, the embodiment of the present application can also detect the position of the vehicle key in real time. According to the actual distance between the vehicle key and the vehicle, it is determined whether the vehicle is allowed to open the back door, and when the actual distance is less than a certain safety distance, an opening command is sent to the motor to open the back door.

[0082] According to the vehicle back door control method proposed in the embodiment of the present application, the first user data of the user collected by at least one ultrasonic sensor set at the rear of the vehicle and the rear bumper can be used to identify the user's first position movement state, and when the first position movement state meets certain opening conditions and the distance between the user and the vehicle is less than a certain distance for a duration greater than a certain duration, the vehicle back door is opened, and the user's intention is judged more accurately. The user can open the back door without additional actions, and no additional components are required. It can adapt to more scenes and different types of vehicles, greatly improving the user's experience, with high intelligent procedures and security, and stronger operability and convenience. Therefore, the problems of increasing the user's additional actions, reducing the convenience of vehicle use, increasing the cost of buying a car, reducing user satisfaction, and leading to poor intelligence and feasibility of the vehicle in the related art are solved.

[0083] Next, the vehicle tailgate control device proposed in accordance with the embodiment of the present application will be described with reference to the accompanying drawings.

[0084] Figure 3 It is a block diagram of a control device for a vehicle tailgate provided according to an embodiment of the present application.

[0085] like Figure 3As shown, the control device 10 of the vehicle tailgate has a plurality of ultrasonic sensors disposed at the rear end and rear bumper of the vehicle, wherein the device 10 includes: a first acquisition module 100 , a first judgment module 200 and a control module 300 .

[0086] The first acquisition module 100 is used to acquire first user data collected by at least one sensor among the multiple ultrasonic sensors.

[0087] The first determination module 200 is used to identify a first position movement state of a user based on first user data, and determine whether the first position movement state meets a preset activation condition.

[0088] The control module 300 is configured to open the back door of the vehicle when the first position moving state satisfies a preset opening condition and the distance between the user and the vehicle is less than a preset distance for a duration greater than a preset duration.

[0089] Optionally, in one embodiment of the present application, it further includes: a detection module and a first opening module.

[0090] The detection module is used to detect the actual distance between the vehicle key and the vehicle before opening the back door of the vehicle.

[0091] The first opening module is used to allow the back door to be opened when it is detected that the actual distance is less than a preset safety distance.

[0092] Optionally, in one embodiment of the present application, it further includes: a second judgment module and a second opening module.

[0093] The second judgment module is used to judge whether the vehicle is in the automatic opening mode of the tailgate before opening the tailgate of the vehicle.

[0094] The second opening module is used to allow the tailgate to be opened when the vehicle is in the tailgate automatic opening mode.

[0095] Optionally, in one embodiment of the present application, the first judgment module 200 includes: an extraction unit and a determination unit.

[0096] The extraction unit is used to extract the distance feature of the user at each moment according to the first user data.

[0097] The determination unit is used to determine whether the first position movement state is an approaching state or a leaving state according to the distance characteristics at each moment.

[0098] Optionally, in an embodiment of the present application, it further includes: a second acquisition module, a third judgment module and a closing module.

[0099] The second acquisition module is used to acquire second user data collected by at least one sensor among the multiple ultrasonic sensors after the back door of the vehicle is opened.

[0100] The third judgment module is used to identify the second position movement state of the user based on the second user data, and judge whether the second position movement state meets the preset closing condition.

[0101] The closing module is used to close the back door of the vehicle when the moving state of the second position meets the preset closing condition.

[0102] It should be noted that the above explanation of the embodiment of the vehicle tailgate control method is also applicable to the vehicle tailgate control device of this embodiment, and will not be repeated here.

[0103] According to the vehicle tailgate control device proposed in the embodiment of the present application, the first user data of the user collected by at least one ultrasonic sensor arranged at the rear of the vehicle and the rear bumper can be used to identify the user's first position movement state, and when the first position movement state meets certain opening conditions and the distance between the user and the vehicle is less than a certain distance for a duration greater than a certain duration, the vehicle tailgate is opened, and the user's intention is judged more accurately. The user can open the tailgate without additional actions, and no additional components are required. It can adapt to more scenarios and different types of vehicles, greatly improving the user's experience, with high intelligent procedures and security, and stronger operability and convenience. Therefore, the problems of increasing the user's additional actions, reducing the convenience of vehicle use, increasing the cost of buying a car, reducing user satisfaction, and leading to poor intelligence and feasibility of the vehicle in the related art are solved.
