Description

Technical Field

[0002] Ultra-Wideband (UWB) is a wireless communication technology characterized by the use of very large bandwidth for short-distance and high-speed data transmission.

[0063] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0064] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0065] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present invention difficult to understand.

[0066] It is worth mentioning that the positioning principle of the UWB node in the ranging positioning mode is: the UWB key sends a pulse signal, the UWB node receives the pulse signal, and measures the time it takes for the signal to propagate between the two modules through the flight time and arrival time difference of the pulse signal, thereby calculating the distance.

[0067] The kick detection principle of the UWB node in radar mode is as follows: the UWB node transmits a UWB signal, receives the echo of the signal after it is reflected by an obstacle, and analyzes the echo to detect surrounding objects and their motion status.

[0068] Figure 1 FIG. 1 is a schematic diagram of an implementation environment of a vehicle back door control method according to an exemplary embodiment of the present application. Figure 1 As shown in FIG. 1 , a plurality of UWB nodes are usually arranged on a vehicle to realize different functions. In order to arrange the plurality of UWB nodes on the vehicle body more evenly, the vehicle body can be configured as follows: Figure 1As shown, two UWB nodes are respectively arranged on opposite sides of the front of the vehicle, two UWB nodes are respectively arranged on opposite sides of the rear of the vehicle, and a UWB master node is arranged on the roof near the front windshield. Among them, since the UWB master node is close to other UWB nodes, it can better receive the signals sent by other UWB nodes. Usually, some algorithms can be preset in the UWB master node to process the information sent by other UWB nodes.

[0069] See also Figure 2 , Figure 2 is a flowchart of a method of an exemplary embodiment of the present application. The method can be applied to Figure 1 It should be understood that the method can also be applied to other exemplary implementation environments and be specifically executed by devices in other implementation environments, and this embodiment does not limit the implementation environment to which the method is applicable.

[0070] like Figure 2 As shown, in an exemplary embodiment, the vehicle back door control method includes at least steps S210 to S240, which are described in detail as follows:

[0071] Step S210, receiving the location information of the UWB key sent by the target UWB node;

[0072] Step S220, judging whether the UWB key is located in the trigger area according to the location information of the UWB key and the location information of the preset trigger area;

[0073] Step S230, when the UWB key is in the trigger area, determining whether the state of the UWB key satisfies a first condition for opening the back door, wherein determining whether the first condition is satisfied includes determining whether the UWB key is continuously in the trigger area within a first preset time period;

[0074] Step S240, when the first condition is met, executing the process of controlling the opening of the back door.

[0075] Before step S210, the UWB positioning function must be turned on first. In some embodiments, the UWB positioning function can be turned on only when the UWB key is within a certain range close to the vehicle. Among them, before the UWB positioning function is turned on, other positioning technologies can be used to determine whether the UWB key is within a certain range of the vehicle. Taking Bluetooth positioning technology as an example, when a user carries a UWB key close to the vehicle, the UWB key and the UWB master node can be connected via Bluetooth. The UWB master node determines the distance between the UWB key and the vehicle through Bluetooth positioning technology, and the UWB positioning function can be turned on within a preset range from the vehicle (the preset range is set according to demand, for example, it can be set to 10 meters, 12 meters or 8 meters, etc.), and the user's real-time location trajectory is detected through UWB positioning technology. In the embodiment of the present application, the UWB positioning technology is turned on when the UWB key is within a preset range close to the vehicle, which can reduce energy consumption on the one hand, and on the other hand, it is conducive to improving positioning accuracy.

[0076] In step S210, the target UWB node may be preset, which may be Figure 1 All or part of the five UWB nodes. .

[0077] In step S220, the trigger area is the area near the back door of the rear of the vehicle. The trigger area can be preset according to the vehicle model, etc. As an example, a 1m long and 0.5m wide area behind the vehicle can be set as the trigger area. When the UWB key is within the trigger area, it can be further determined whether the user has the need to open the back door, that is, whether the conditions for the back door opening requirement are met in the subsequent steps.

[0078] It is worth mentioning that after determining the trigger area, the location information of the trigger area needs to be determined, which can be determined using the target UWB node and the UWB key. Specifically, the UWB key is carried and moved within the trigger area, and the target UWB node continuously detects the location information of the UWB key, thereby determining the location range of the trigger area, that is, determining the location information of the trigger area. In some embodiments, the target UWB node can be Figure 1 The two UWB nodes on both sides of the rear of the car are shown. Because the two UWB nodes on both sides of the rear of the car are close to the trigger area, when the UWB key is in the trigger area, the above nodes can receive a stronger pulse signal.

[0079] In step 230, when the UWB key is located in the trigger area, it is determined whether the state of the UWB key meets the first condition of the back door opening requirement, including determining whether the UWB key is continuously located in the trigger area within the first preset time. It is easy to understand that when the user carries the UWB key and is continuously located in the trigger area within the first preset time, it can be said that the user may have a back door opening requirement. Based on this, determining whether the UWB key is continuously located in the trigger area within the first preset time is conducive to further analyzing whether the user has a back door opening requirement, and thus can more accurately control the back door opening. Among them, to determine whether the UWB key is continuously located in the trigger area within the first preset time, the location information of the UWB key can be continuously collected by the above-mentioned target UWB node, and the above-mentioned UWB master node analyzes the location information continuously uploaded by the target UWB node and the location information of the trigger area, so as to determine whether the UWB key is continuously located in the trigger area within the first preset time. The first preset time can be set according to actual needs, for example, it can be set to 3s or 5s.

[0080] See also Figure 3 In some embodiments, when the UWB key is located in the trigger area, it is first determined whether the vehicle state meets the second condition of the back door opening requirement, and only when the second condition is met, it is determined whether the UWB key meets the first condition. The second condition includes that the back door of the vehicle is closed and the vehicle is not in motion.

[0081] The back door is usually required to be opened only when the back door is closed and the vehicle is not in motion. Based on this, the embodiment of the present application first determines whether the vehicle state meets the second condition of the back door opening requirement. If the second condition is met, it further determines whether the first condition is met. Otherwise, the next step of the determination process is not triggered, and the back door automatic opening process is directly terminated.

[0082] Through the above settings, only when the second condition is met will further analyze whether the user has a need to open the back door, which is conducive to correctly identifying user needs; when the second condition is not met, the judgment process of automatically opening the back door is directly stopped, which is conducive to saving computing resources.

[0083] In step S240, if the first condition is met, the process of controlling the opening of the back door is executed; if the first condition is not met, the process of controlling the opening of the back door is not executed, that is, the process of the opening of the back door is not triggered this time, and the back door opening function is exited. It is worth mentioning that the process of controlling the opening of the back door in the embodiment of the present application is not equivalent to directly controlling the opening of the back door. The process of controlling the opening of the back door of the present application may also include other steps in addition to controlling the opening of the back door, for example, determining whether there is an obstacle that prevents the opening of the back door, controlling the opening of the back door when there is no obstacle, and / or determining whether the UWB key carried by the user is still in the trigger area, and controlling the opening of the back door when the UWB key exits the trigger area.

[0084] In an embodiment of the present application, the target UWB node in the ranging and positioning mode obtains the location information of the UWB key to further determine whether to execute the process of controlling the opening of the tailgate. There is no need to add a UWB node in the radar mode to detect the kicking action. That is, the present application can use the vehicle-mounted UWB node in the ranging and positioning mode to control whether the tailgate of the vehicle is opened, which is conducive to cost saving.

[0085] Optionally, the determining whether the state of the UWB key satisfies the first condition further includes:

[0086] Determining whether the UWB key is continuously in a stationary state within the first preset time period;

[0087] The process of executing the process of controlling the opening of the back door when the first condition is met includes:

[0088] When the UWB key is continuously located in the trigger area within the first preset time period and is continuously in a stationary state within the first preset time period, a process of controlling the opening of the back door is executed.

[0089] In this implementation, the first condition also includes that the UWB key remains stationary for the first preset time period. Meeting this condition can further indicate that the user may have a need to open the back door.

[0090] In the embodiment of the present application, when the UWB key is continuously located in the trigger area within a first preset time period and is continuously in a stationary state within a first preset time period, the process of controlling the opening of the tailgate is executed, which can more accurately identify the user's intention and further more accurately determine whether to open the tailgate, thereby reducing misoperation.

[0091] In some embodiments, when the UWB key is located in the trigger area, it can be immediately determined whether the UWB key is continuously located in the trigger area within a first preset time period and whether it is continuously in a stationary state within the first preset time period. If this is not satisfied, the process of triggering the opening of the back door is immediately stopped.

[0092] In other embodiments, see Figure 3 , within a second preset time length, it can be continuously determined whether the UWB key is continuously located in the trigger area within a first preset time length and whether it is continuously in a stationary state within the first preset time length, and the second preset time length is greater than the first preset time length.

[0093] The second preset time length is longer than the first preset time length, and whether the first condition is satisfied can be determined within a longer time range. As an example, the second preset time length can be set to 10 seconds, and the first preset time length can be set to 3 seconds. In this example, it is continuously determined within 10 seconds whether the UWB key is stationary in the trigger area within 3 seconds. The first condition is satisfied as long as the UWB key is stationary in the trigger area for 3 seconds within 10 seconds.

[0094] It is worth mentioning that when a user enters the trigger area with a UWB key, the user may not be aware that he has entered the trigger area. In order to trigger the back door opening function, the user may choose to move continuously to the center of the trigger area before stopping. Based on this, the embodiment of the present application determines whether the first condition is met within the second preset time period, which can more accurately identify the user's intention than determining whether the first condition is met within the first preset time period.

[0095] Optionally, the UWB key is provided with a gravity sensor for determining whether the UWB key is in a stationary state, and the determining whether the UWB key is in a stationary state within the first preset time period includes:

[0096] It is determined whether the gravity sensor continues to send a stationary state signal within the first preset time period, wherein the stationary state signal is used to indicate that the UWB key is in a stationary state.

[0097] Gravity sensor (Gsensor) can sense the changes in acceleration force on an object, which may come from various situations, such as shaking, falling, rising or falling of the object. Gsensor can convert these physical changes into electrical signals, and then perform accurate calculations and analysis through a microprocessor to achieve preset programming functions. In the embodiment of the present application, a gravity sensor is used to determine whether the UWB key is in a stationary state, which can be more accurate than determining whether the UWB key is in a stationary state through UWB positioning and other methods.

[0098] Alternatively, see Figure 3 The process of executing the control of opening the back door includes:

[0099] Sending a prompt command to a body control module (BCM), wherein the body control module is used to control a target vehicle-mounted device to send a warning signal according to the prompt command to prompt that the back door is ready to be opened;

[0100] Determining whether the UWB key moves outside the triggering area after the warning signal is issued;

[0101] When the UWB key moves out of the trigger area, a command for controlling the opening of the rear door is sent to the vehicle body controller.

[0102] In this embodiment, the vehicle body controller can control the target vehicle-mounted device to send out a warning signal according to the prompt instruction, and the target vehicle-mounted device can be a double flash warning light and / or a voice alarm device, etc. As an example, in the case where the target vehicle-mounted device includes a double flash warning light, the prompt instruction may include an instruction to control the double flash warning light to flash; in the case where the target vehicle-mounted device includes a voice alarm device, the prompt instruction may also include an instruction to control the voice alarm device to send out a preset voice, and the content of the preset voice, for example, if the back door needs to be opened, please back up, etc.

[0103] After the above-mentioned warning signal is issued, if the user does not need to open the back door, there is no need to carry the UWB key outside the trigger area, and the back door will not be opened this time; if the user has the need to open the back door, he or she can carry the UWB key outside the trigger area to prevent the user from being injured during the back door opening process. When the UWB master node detects that the UWB key moves outside the trigger area, it sends an instruction for controlling the opening of the back door to the body controller, and the body controller controls the opening of the back door.

[0104] After issuing a warning signal, the embodiment of the present application determines whether the UWB key has moved out of the trigger area. If moved out of the trigger area, the tailgate is controlled to open. This can more accurately identify the user's intention to open the tailgate and prevent the user from being injured during the process of opening the tailgate.

[0105] Alternatively, see Figure 3 , the determining whether the UWB key moves outside the triggering area after the warning signal is issued includes:

[0106] Determining whether the UWB key moves outside the triggering area within a third preset time period after the warning signal is issued;

[0107] When the UWB key moves out of the trigger area, sending an instruction for controlling the opening of the back door to the vehicle body controller includes:

[0108] When the UWB key moves out of the trigger area within a third preset time period, an instruction for controlling the opening of the back door is sent to the vehicle body controller.

[0109] In this embodiment, as long as the user moves out of the trigger area with the UWB key within the third preset time, the back door can be controlled to open. The third preset time can be determined according to the average walking speed of the user and the size of the trigger area. For example, the third preset time is 5s, 6s or 7s.

[0110] It is easy to understand that it takes a certain amount of time for the user to move the UWB key outside the trigger area. The embodiment of the present application can better meet the user's needs by reserving a certain amount of retreat time for the user.

[0111] It is worth mentioning that the warning signal sent by the above-mentioned target vehicle-mounted device can be a continuous warning signal, such as the double flash warning lights flashing continuously. In some embodiments, if the UWB key moves outside the trigger area or does not move outside the trigger area within the third preset time, the UWB master node can send an instruction to the vehicle controller to control the target vehicle-mounted device to stop sending the warning signal. In other embodiments, after the target vehicle-mounted device continues to send the warning signal for a period of time reaching the above-mentioned third preset time, the body controller can also automatically control the target vehicle-mounted device to stop sending the warning signal.

The device can be applied to Figure 1 The implementation environment shown is specifically configured in the UWB master node, and may also be applicable to other exemplary implementation environments and specifically configured in other devices. This embodiment does not limit the implementation environment to which the device is applicable.

[0115] A first determination module 420 is used to determine whether the UWB key is located in the trigger area according to the location information of the UWB key and the location information of the preset trigger area;

[0116] A second judgment module 430 is used to judge whether the state of the UWB key meets the first condition of the tailgate opening requirement when the UWB key is located in the trigger area, wherein the judgment whether the first condition is met includes judging whether the UWB key is continuously located in the trigger area within a first preset time period;

[0117] The execution module 440 is used to execute the process of controlling the opening of the back door when the first condition is met.

[0122] Optionally, the second determining module 430 is specifically configured to:

[0123] Within a second preset time length, it is determined whether the UWB key is continuously located in the trigger area within a first preset time length and whether it is continuously in a stationary state within the first preset time length, and the second preset time length is greater than the first preset time length.

[0124] Optionally, the UWB key is provided with a gravity sensor for determining whether the UWB key is in a stationary state, and the second determination module 430 is specifically configured to:
