[0002] With the popularization of automobiles and the continuous improvement of technology, more and more users are taking trailer travel as a form of leisure. Therefore, users' demand for convenience when connecting trailers is also increasing.

[0003] In the related art, due to factors such as the vehicle shape, the type of trailer hook, and the placement of the vehicle's rearview camera, users are required to reverse the vehicle to connect the trailer. However, since users are not clear about the location of the trailer hook and the actual distance to the trailer connection point, collision risks are inevitable during the trailer connection process. Therefore, how to improve the convenience of connecting a trailer to improve vehicle safety has become an urgent problem to be solved. Summary of the invention

[0004] The present application provides a vehicle display method, a vehicle display device and a vehicle, wherein the method can improve the convenience when connecting a trailer to improve the safety of the vehicle.

[0005] In a first aspect, a vehicle display method is provided, the method comprising:

[0006] In response to an activation command of a trailer function in the vehicle, determining a current gear position of the vehicle;

The target auxiliary line indicates the moving trajectory of the trailer hook, and the target panoramic image is displayed on the display screen of the vehicle. Since the target panoramic image includes the trailer hook and the target auxiliary line, compared with estimating the moving direction and position of the trailer hook in the vehicle through the reversing auxiliary line, the present application determines the target auxiliary line of the trailer hook through the reversing auxiliary line and the target position of the trailer hook, and displays the target auxiliary line and the trailer hook on the display screen. It can accurately locate the moving trajectory and position of the trailer hook during the connection process between the vehicle and the trailer, thereby accurately aligning the connecting device of the trailer hook with the trailer, avoiding collision between the trailer hook and the trailer, improving the convenience of connecting the vehicle to the trailer, and thus improving the safety of the vehicle.

[0017] The above technical solution obtains the target auxiliary line by parallel processing of the initial auxiliary line based on the reversing auxiliary line; since the target auxiliary line is parallel to the reversing auxiliary line, the initial auxiliary line is processed in parallel through the reversing auxiliary line to obtain the target auxiliary line. As the steering wheel angle changes during the vehicle's driving process, the target auxiliary line will be continuously updated along with the reversing auxiliary line, thereby ensuring the accuracy of the target auxiliary line, thereby indicating the moving trajectory of the trailer hook through the target auxiliary line, making the connection between the vehicle and the trailer more convenient.

[0021] The above technical solution determines the target position of the trailer hook on the rear bumper of the vehicle, and takes the target position as the starting point and extends the line in the driving direction to obtain the initial auxiliary line; since the initial auxiliary line takes the target position of the trailer hook on the rear bumper of the vehicle as the starting point and extends the line in the driving direction of the vehicle, it can ensure that the initial auxiliary line is consistent with the driving direction of the vehicle.

[0027] Obtaining a reference position of a target object blocking the trailer hook;

[0028] Based on the reference position and the target position, the position to be added in the initial panoramic image is determined.

[0029] In the above technical scheme, if the trailer hook is not detected in the initial panoramic image, the reference position of the target object blocking the trailer hook is obtained, and based on the reference position and the target position, the position to be added in the initial panoramic image is determined; since the position to be added in the initial panoramic image is obtained through the two-dimensional data of the reference position and the target position of the target object blocking the trailer hook, the accuracy of the position to be added can be ensured, thereby improving the accuracy of the target auxiliary line of the trailer hook, and further improving the convenience in the process of connecting the vehicle and the trailer.

[0051] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0052] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0053] It should be noted that due to factors such as the vehicle shape, the type of trailer hook installed, and the layout of the vehicle's rearview camera, the user needs to reverse to connect the trailer. However, since the user is not clear about the position of the trailer hook and the actual distance to the trailer connection point, the risk of collision is inevitable during the trailer connection process. In view of this, the present application proposes a vehicle display method, a vehicle display device, and a vehicle. Through the embodiments of the present application, when the vehicle is in reverse gear, by displaying the trailer hook and the target auxiliary line of the trailer hook in the target panoramic image, the driver can determine the moving trajectory of the trailer hook, so that the position of the trailer hook and the trailer connection point can be determined through the target panoramic image, thereby improving the convenience when connecting the trailer to improve vehicle safety.

[0054] Figure 1 It is a scene schematic diagram of a vehicle display method provided in an embodiment of the present application.

[0055] For example, Figure 1 (a) in FIG. 1 shows a panoramic image of a target corresponding to a bird's-eye view of the vehicle 100. Figure 1(b) shows the target panoramic image corresponding to the rear view angle of the vehicle 100.

[0056] For example, Figure 1 As shown in (a), when the trailer function is on in the vehicle 100, the current gear position of the vehicle 100 is determined. When the current gear position of the vehicle 100 is in reverse gear, based on the reversing auxiliary line 110 of the vehicle 100 and the target position of the trailer hook 120, the target auxiliary line 130 of the trailer hook 120 is obtained, the target auxiliary line 130 indicates the moving trajectory of the trailer hook 120, and the target panoramic image is displayed on the display screen of the vehicle 100, and the target panoramic image includes the trailer hook 120 and the target auxiliary line.

[0057] Exemplarily, the driving direction of the vehicle is obtained, an initial auxiliary line is determined based on the driving direction of the vehicle and a target position of the trailer hook, and the initial auxiliary line is adjusted based on the reversing auxiliary line to obtain a target auxiliary line.

[0058] Specifically, the driving direction of the vehicle is obtained, the target position of the trailer hook on the rear bumper of the vehicle is determined, and an extension line is made in the driving direction with the target position as the starting point to obtain an initial auxiliary line; the initial auxiliary line is parallel processed based on the reversing auxiliary line to obtain a target auxiliary line, and the target auxiliary line is parallel to the reversing auxiliary line.

[0059] On this basis, based on the target position of the trailer hook, the position to be added in the initial panoramic image is determined, and the initial panoramic image includes a reversing auxiliary line; taking the position to be added in the initial panoramic image as the starting point, the target auxiliary line is added to obtain the target panoramic image.

[0060] For example, Figure 1 As shown in (b), if the trailer hook 120 is not detected in the initial panoramic image, the target position of the trailer hook 120 on the rear bumper 140 of the vehicle is determined, and the reference position of the target object blocking the trailer hook 120 is obtained, based on the reference position and the target position, the position to be added in the initial panoramic image is determined, and based on the target size of the trailer hook 120, a target image of the trailer hook 120 is generated, the target image of the trailer hook 120 is added to the position to be added in the initial panoramic image, and with the position to be added as the starting point, a target auxiliary line 130 is added to obtain a target panoramic image, and the target panoramic image includes the reversing auxiliary line 110, the trailer hook 120 and the target auxiliary line 130.

[0061] Exemplarily, the target auxiliary line can be a single dashed line or a double dashed line. The display mode of the target auxiliary line can be determined according to actual conditions and is not specifically limited here.

[0062] Figure 2It is a schematic diagram of the framework of a vehicle display method provided in an embodiment of the present application.

[0063] For example, Figure 2 As shown, the control unit in the vehicle is used to display the on or off control of the trailer function. The user determines the on / off state of the trailer function in the vehicle by clicking the on / off virtual control of the trailer function in the control unit. Specifically, when the user clicks the on control of the trailer function, the control unit sends a request to turn on the trailer function to the Around View Monitor (AVM); when the user clicks the off control of the trailer function, the control unit sends a request to turn off the trailer function to the AVM. In addition, the on / off state of the trailer function in the control unit does not need to be memorized. When the vehicle is powered off and then powered on again, the on / off state is based on the state fed back by the AVM.

[0064] Optionally, the control unit may be a central control screen of the vehicle; or, the control unit may be a physical button in the vehicle. The control unit may be determined according to actual conditions and is not specifically limited here.

[0065] Exemplarily, the detection module is used to detect the coupling state between the vehicle and the trailer, and send the coupling state between the vehicle and the trailer to the AVM.

[0066] Exemplarily, when the AVM receives the information of turning on the trailer function from the control unit, it turns on the trailer function of the vehicle, the trailer hook of the vehicle is in an unfolded state, and generates a target panoramic image including the trailer hook and the target auxiliary line according to the calibrated target auxiliary line, displays the target panoramic image on the display screen, and synchronizes the instruction of turning on the trailer function to the control unit. When the AVM receives the information of turning off the trailer function from the control unit, it turns off the trailer function of the vehicle, displays the initial panoramic image on the display screen, and synchronizes the instruction of turning off the trailer function to the control unit.

[0067] For example, when the current gear of the vehicle is in reverse gear, the AVM identifies whether the vehicle and the trailer are in a coupled state. When the vehicle and the trailer are in a coupled state, the initial panoramic image is displayed on the display screen. When the vehicle and the trailer are not in a coupled state, the target panoramic image is obtained according to the target auxiliary line and the target panoramic image is displayed on the display screen. In addition, when the vehicle and the trailer are switched from an uncoupled state to a coupled state, the target panoramic image on the display screen is switched to the initial panoramic image.

[0068] It is understandable that when the vehicle is hooked to the trailer, the vehicle and the trailer are in a coupled state, and when the vehicle is not hooked to the trailer, the vehicle and the trailer are not in a coupled state.

[0069] Optionally, the target auxiliary line of the trailer hook may be calibrated according to the method in the disclosed embodiment, which will not be described in detail here.

[0070] It should be noted that the target panoramic image including the trailer hook and the target auxiliary lines is displayed in the vehicle's top-view perspective and the vehicle's rear-view perspective; the display mode of the target auxiliary lines in the target panoramic image can be a single dotted line or a double dotted line; of course, the display mode of the target auxiliary lines can be determined according to actual conditions and is not specifically limited here.

[0071] In addition, since the target auxiliary line and the reversing auxiliary line of the trailer hook are in the same direction (the target auxiliary line of the trailer hook can bend with the steering guide, that is, as the reversing auxiliary line is updated, the target auxiliary line of the trailer hook is updated accordingly), the target auxiliary line and the reversing auxiliary line in the target panoramic image are displayed in different display styles to facilitate users to distinguish between the reversing auxiliary line and the target auxiliary line of the trailer hook.

[0072] Figure 3 It is a schematic flow chart of a vehicle display method provided in an embodiment of the present application.

[0073] For example, Figure 3 The method shown can be executed by the vehicle's panoramic monitoring imaging system, vehicle controller or chip.

[0074] For example, Figure 3 As shown, the method 300 includes the following processes:

[0075] S310, in response to a start instruction of a trailer function in the vehicle, determining a current gear position of the vehicle.

[0076] It should be noted that the trailer function in the vehicle is used to tow other equipment so that the other equipment can travel at the same time as the vehicle. Taking the vehicle towing a trailer as an example, the vehicle towing the trailer is coupled to the trailer device of the trailer by coupling the vehicle's trailer hook. However, in the related art, when the vehicle's trailer hook is in an unfolded state and the vehicle is in reverse gear to connect the trailer, it is necessary to use a panoramic image to observe the estimated position of the trailer hook so that the estimated position is aligned with the trailer device of the trailer. Since the estimated position is not accurate enough, the trailer hook and the trailer may collide, making it difficult to ensure the safety of the vehicle.

[0077] Furthermore, the target auxiliary line of the trailer hook is accurately determined through the vehicle's reversing auxiliary line and the target position of the trailer hook in the vehicle, so that a target auxiliary line of the trailer hook and a target panoramic image of the trailer hook are displayed on the vehicle's display screen, making it more convenient to connect the vehicle with the trailer.

[0078] Exemplarily, it is determined whether the trailer function in the vehicle is turned on. In response to an instruction to turn on the trailer function in the vehicle, the trailer hook of the vehicle is controlled to be in an extended state, so that the trailer hook can be coupled with the trailer at any time; in response to an instruction to turn off the trailer function in the vehicle, the trailer hook of the vehicle is controlled to be in a retracted state.

[0079] Optionally, the on instruction of the trailer function in the vehicle can be determined by monitoring the trailer control in the vehicle. Specifically, if the on operation of the trailer control in the vehicle is detected, it is determined that the on instruction of the trailer function in the vehicle is detected; if the off operation of the trailer control in the vehicle is detected, it is determined that the off instruction of the trailer function in the vehicle is detected. Alternatively, the on instruction of the trailer function in the vehicle can be determined by recognizing a voice instruction; for example, if a voice instruction "Hello, Xiao A, please turn on the trailer function" is recognized. The on instruction of the trailer function in the vehicle can be determined according to actual conditions and is not specifically limited here.

[0080] For example, the vehicle may be a passenger car; of course, the vehicle may also be, but not limited to, a truck, a commercial vehicle, a residential vehicle, a tractor, a towing vehicle, a bus, etc. The vehicle may be determined according to actual conditions and is not specifically limited here.

[0081] Exemplarily, the trailer may be a camper, a horse trailer, a harvester, a motorhome, etc. The trailer may have an inertia brake, which may be determined according to actual conditions and is not specifically limited herein.

[0082] Exemplarily, in response to an instruction to turn on the trailer function in the vehicle, the current gear position of the vehicle is determined. Specifically, when the trailer function in the vehicle is turned on, the trailer hook in the vehicle is controlled to be in an unfolded state, and the current gear position of the vehicle is determined. The trailer hook in the vehicle is installed at the rear of the vehicle. When the vehicle is in reverse gear, it is determined that the vehicle needs to be connected to a trailer. Therefore, whether the vehicle needs to be connected to a trailer is determined by the current gear position of the vehicle.

[0083] Optionally, the current gear of the vehicle may be forward gear, reverse gear, neutral gear, etc.

[0084] S320: If the current gear is in reverse gear, a target auxiliary line of the trailer hook is obtained based on the reverse auxiliary line of the vehicle and the target position of the trailer hook.

[0085] It should be noted that the target auxiliary line is used to indicate the moving track of the trailer hook. The target auxiliary line indicates the moving track of the trailer hook during the vehicle reversing process. The moving position of the trailer hook can be determined as the vehicle travels through the target auxiliary line. In addition, the target auxiliary line can be a pre-calibrated auxiliary line or generated in real time, which is not specifically limited here.

[0086] For example, the reversing assistance lines are captured by a sensor at the rear of the vehicle in real time and displayed on a display screen. At the same time, the reversing assistance lines are displayed on the display screen to help the driver judge the distance and position of the vehicle and obstacles.

[0087] Exemplarily, when the vehicle's current gear position is in reverse gear and it is determined that the vehicle needs to be connected to a trailer, a target auxiliary line of the trailer hook is obtained based on the vehicle's reversing auxiliary line and the target position of the trailer hook. The target auxiliary line indicates the moving trajectory of the trailer hook, so that the driver can determine the moving position of the trailer hook through the target auxiliary line during the reversing process.

[0088] Specifically, the vehicle's driving direction is obtained, and an initial auxiliary line is determined based on the vehicle's driving direction and the target position of the trailer hook. The direction of the initial auxiliary line is the same as the vehicle's driving direction, and based on the reversing auxiliary line and the initial auxiliary line, a target auxiliary line is obtained, so that the target auxiliary line of the trailer hook is located on the inner side of the reversing auxiliary line, so as to instruct the driver to reverse through the target auxiliary line, thereby connecting the vehicle with the trailer.

[0089] Optionally, the vehicle's driving direction is used to indicate the vehicle's direction of travel. When the vehicle is in reverse gear, the vehicle's driving direction may include, but is not limited to: directly behind the vehicle, to the left rear of the vehicle, and to the right rear of the vehicle; or, the vehicle's driving direction may be determined by the angle between the vehicle's driving direction and the vehicle's longitudinal axis, for example, 30 degrees counterclockwise, i.e., directly behind the vehicle is the positive direction, and the direction 30 degrees counterclockwise is the driving direction.

[0090] Exemplarily, the target auxiliary line is obtained by adjusting the initial auxiliary line through the reversing auxiliary line, so that the direction of the target auxiliary line is consistent with that of the reversing auxiliary line. For example, the reversing auxiliary line includes a first auxiliary line and a second auxiliary line, and a first distance between the trailer hook and the first side of the vehicle and a second distance between the trailer hook and the second side of the vehicle are determined. The initial auxiliary line is adjusted through the first distance between the trailer hook and the first side of the vehicle and the second distance between the trailer hook and the second side of the vehicle to obtain the target auxiliary line, so that the distance from any point in the target auxiliary line to the first auxiliary line is the first distance, and the distance from any point in the target auxiliary line to the second auxiliary line is the second distance. The auxiliary line on the first side is the first auxiliary line, and the auxiliary line on the second side is the second auxiliary line.

[0091] The above technical solution obtains the driving direction of the vehicle, determines the initial auxiliary line based on the driving direction of the vehicle and the target position of the trailer hook, and obtains the target auxiliary line based on the reversing auxiliary line and the initial auxiliary line; since the initial auxiliary line is determined by the driving direction of the vehicle and the target position of the trailer hook, and the initial auxiliary line is adjusted by the reversing auxiliary line, the direction of the target auxiliary line can be kept consistent with that of the reversing auxiliary line, so that the moving trajectory of the trailer hook in the vehicle is prompted by the target auxiliary line, thereby improving the convenience of connecting the vehicle with the trailer.

[0092] Exemplarily, the initial auxiliary line is determined based on the driving direction of the vehicle and the target position of the trailer hook. Specifically, the target position of the trailer hook on the rear bumper of the vehicle is determined, and the target position is used as the starting point to extend the line in the driving direction to obtain the initial auxiliary line.

[0093] Exemplarily, the target position of the trailer hook is used to indicate the installation position of the trailer hook in the vehicle. For example, the target position of the trailer hook may be the middle position of the rear bumper of the vehicle; or, the target position of the trailer hook may be the left position of the rear bumper of the vehicle. The target position of the trailer hook may be determined according to actual conditions and is not specifically limited here.

[0094] For example, if the target position of the trailer hook on the rear bumper of the vehicle is determined to be the middle position of the bumper, and the vehicle is traveling in the rearward direction, then an extension line is drawn in the rearward direction with the middle position of the vehicle's bumper as the starting point to obtain the initial auxiliary line.

[0095] The above technical solution determines the target position of the trailer hook on the rear bumper of the vehicle, and takes the target position as the starting point and extends the line in the driving direction to obtain the initial auxiliary line; since the initial auxiliary line takes the target position of the trailer hook on the rear bumper of the vehicle as the starting point and extends the line in the driving direction of the vehicle, it can ensure that the initial auxiliary line is consistent with the driving direction of the vehicle.

[0096] Exemplarily, the initial auxiliary line is adjusted based on the reversing auxiliary line to obtain the target auxiliary line. Specifically, the initial auxiliary line is parallelized based on the reversing auxiliary line to obtain the target auxiliary line, so that the target auxiliary line is parallel to the reversing auxiliary line.

[0097] Specifically, the slope of the reversing auxiliary line is determined by a vector analysis algorithm, and the slope of the initial auxiliary line is ensured to be the same as that of the reversing auxiliary line on the same horizontal line. In order to ensure that the slope of the initial auxiliary line and the reversing auxiliary line are the same, the position and angle of the initial auxiliary line are adjusted so that the initial auxiliary line is aligned and parallel to the reversing auxiliary line to obtain the target auxiliary line. In addition, as the angle of the steering wheel changes during the reversing process, the target auxiliary line and the reversing auxiliary line are updated in real time, but the target auxiliary line always remains parallel to the reversing auxiliary line.

[0098] The above technical solution obtains the target auxiliary line by parallel processing of the initial auxiliary line based on the reversing auxiliary line; since the target auxiliary line is parallel to the reversing auxiliary line, the initial auxiliary line is processed in parallel through the reversing auxiliary line to obtain the target auxiliary line. As the steering wheel angle changes during the vehicle's driving process, the target auxiliary line will be continuously updated along with the reversing auxiliary line, thereby ensuring the accuracy of the target auxiliary line, thereby indicating the moving trajectory of the trailer hook through the target auxiliary line, making the connection between the vehicle and the trailer more convenient.

[0099] Exemplarily, if the current gear is in reverse gear, determine whether the vehicle and the trailer are in a coupled state. If the vehicle and the trailer are not in a coupled state, obtain the target auxiliary line of the trailer hook based on the vehicle's reversing auxiliary line and the target position of the trailer hook; if the vehicle and the trailer hook are in a coupled state, display the initial panoramic image on the vehicle's display screen.

[0100] Exemplarily, the coupling status is used to indicate that the vehicle is successfully connected to the trailer, that is, the vehicle is successfully connected to the trailer through the connecting device of the trailer hook. In this case, there is no need to display the position of the trailer hook and the target auxiliary line of the trailer hook. It is only necessary to display the initial panoramic image that does not include the target auxiliary line of the trailer hook and includes the reversing auxiliary line.

[0101] Optionally, the method for generating the target auxiliary line may refer to the method in the aforementioned disclosed embodiment, which will not be described in detail here.

[0102] For example, in response to a command to turn on the trailer function in the vehicle, the current gear position of the vehicle is determined. When the current gear position of the vehicle is in reverse, it is determined whether the vehicle and the trailer are in a coupled state. When the vehicle and the trailer are in a coupled state, the vehicle and the trailer are successfully connected, and there is no need to display the target auxiliary line of the moving trajectory of the trailer hook in the vehicle. The initial panoramic image is displayed on the display screen. When the vehicle and the trailer are in an uncoupled state, the target panoramic image including the target auxiliary line is displayed on the display screen of the vehicle. In addition, when the vehicle and the trailer are in a coupled state, the target panoramic image is displayed on the display screen, and as the vehicle travels, when the vehicle and the trailer are in a coupled state, the target panoramic image on the display screen is switched to the initial panoramic image.

[0103] According to the above technical solution, if the current gear is in reverse gear, it is determined whether the vehicle and the trailer are in a coupled state. When the vehicle and the trailer are in a coupled state, an initial panoramic image is displayed on the display screen of the vehicle; by determining whether the vehicle and the trailer are in a coupled state, the panoramic image displayed on the display screen is determined, and then the panoramic image displayed on the display screen is switched according to actual needs, which can improve the convenience of connecting the vehicle and the trailer while improving the user experience.

[0104] Exemplarily, based on the target position of the trailer hook, the position to be added in the initial panoramic image is determined, the initial panoramic image includes a reversing auxiliary line, and the target auxiliary line is added with the position to be added in the initial panoramic image as the starting point to obtain the target panoramic image.

[0105] It should be noted that the position to be added is used to indicate the position of the target position of the trailer hook in the initial panoramic image, that is, the position to be added is the position of the trailer hook in the initial panoramic image.

[0106] For example, if the trailer hook is in the middle of the rear bumper of the vehicle, the position to be added in the initial panoramic image is determined to be the middle of the rear bumper in the initial panoramic image. Taking the middle of the rear bumper in the initial panoramic image as the starting point, the target auxiliary line is added to obtain the target panoramic image.

[0107] The above technical scheme determines the position to be added in the initial panoramic image based on the target position of the trailer hook, and the initial panoramic image includes a reversing auxiliary line; takes the position to be added in the initial panoramic image as the starting point, adds the target auxiliary line, and obtains the target panoramic image; since the position to be added is determined based on the target position of the trailer hook, that is, the position to be added indicates the position of the trailer hook in the initial panoramic image, by taking the position to be added in the initial panoramic image as the starting point, adding the target auxiliary line can ensure the accuracy of the target auxiliary line in the target panoramic image, thereby improving the convenience of connecting the vehicle and the trailer.

[0108] It is understandable that due to different vehicle models, the trailer hook in the vehicle may not be displayed in the initial panoramic image. When the trailer hook is not detected in the initial panoramic image, it is necessary to add the trailer hook in the initial panoramic image to ensure that the target panoramic image displayed in the vehicle's display screen includes the vehicle's trailer hook and the target auxiliary line of the trailer hook.

[0109] Exemplarily, based on the reversing auxiliary line of the vehicle and the target position of the trailer hook, a target auxiliary line of the trailer hook is obtained; it is detected whether there is a trailer hook in the initial panoramic image, and when the trailer hook is detected in the initial panoramic image, a target auxiliary line is added with the position to be added in the initial panoramic image as the starting point to obtain a target panoramic image; when the trailer hook is not detected in the initial panoramic image, based on the target size of the trailer hook, a target image of the trailer hook is generated, the target image is added at the position to be added in the initial panoramic image, and a target auxiliary line is added with the position to be added as the starting point to obtain a target panoramic image.

[0110] Exemplarily, the target size of the trailer hook is used to indicate the shape and size of the trailer hook of the vehicle. Based on the shape and size of the trailer hook, a target image of the trailer hook is generated. The target image is a virtual image of the trailer hook, and its shape and size are the same as those of the trailer hook. The target image can be a two-dimensional image. Of course, the target image can also be a three-dimensional image. The target image can be determined based on actual conditions and is not specifically limited here.

[0111] Exemplarily, when the trailer hook is not detected in the initial panoramic image, a target image of the trailer hook is generated based on the target size of the trailer hook, and the target area corresponding to the target object blocking the trailer hook is obtained, and the target area is made transparent, and then the target image of the trailer hook is added to the position to be added, and with the position to be added as the starting point, a target auxiliary line is added to obtain a target panoramic image.

[0112] For example, if the vehicle spare tire blocks the trailer hook in the initial panoramic image, a target image (three-dimensional image) of the trailer hook is generated based on the target size of the trailer hook, and the target area corresponding to the vehicle spare tire is determined, the target area is made transparent, and the target image is added to the position to be added (determined by the vehicle spare tire position and the target position of the trailer hook) to obtain the target panoramic image.

[0113] In the above technical scheme, if the trailer hook is not detected in the initial panoramic image, a target image of the trailer hook is generated based on the target size of the trailer hook, the target image is added at the position to be added in the initial panoramic image, and target auxiliary lines are added with the position to be added as the starting point to obtain a target panoramic image; by determining whether there is a trailer hook in the initial panoramic image, if the trailer hook is not detected in the initial panoramic image, a virtual trailer hook is added to the initial panoramic image and a target auxiliary line of the trailer hook is added, to ensure that the target panoramic image includes the trailer hook and the target auxiliary line, thereby improving the convenience of connecting the vehicle to the trailer.

[0114] Exemplarily, determine whether there is a trailer hook in the initial panoramic image. If there is a trailer hook in the initial panoramic image, determine the position to be added in the initial panoramic image based on the target position of the trailer hook, that is, map the actual position (target position) of the trailer hook to the initial panoramic image, and determine the position to be added corresponding to the trailer hook; if there is no trailer hook in the initial panoramic image, obtain the reference position of the target object that blocks the trailer hook, and determine the position to be added in the initial panoramic image based on the reference position of the target object and the target position of the trailer hook.

[0115] In the above technical scheme, if the trailer hook is not detected in the initial panoramic image, the reference position of the target object blocking the trailer hook is obtained, and based on the reference position and the target position, the position to be added in the initial panoramic image is determined; since the position to be added in the initial panoramic image is obtained through the two-dimensional data of the reference position and the target position of the target object blocking the trailer hook, the accuracy of the position to be added can be ensured, thereby improving the accuracy of the target auxiliary line of the trailer hook, and further improving the convenience in the process of connecting the vehicle and the trailer.

[0116] Exemplarily, the target object may be a tailgate of a vehicle, a spare tire of a vehicle, etc. The target object may be determined according to actual conditions and is not specifically limited here.

[0117] Exemplarily, the reference position of the target object is used to indicate the position of the target object in the vehicle.

[0118] Exemplarily, based on the reference position and the target position, the position to be added in the initial panoramic image is determined. Specifically, the first position in the initial panoramic image is determined based on the reference position, the second position in the initial panoramic image is determined based on the target position, and the position to be added in the initial panoramic image is determined by the first position in the initial panoramic image and the second position in the initial panoramic image.

[0119] S330, displaying the target panoramic image on a display screen of the vehicle.

[0120] It should be noted that the target panoramic image includes a trailer hook and target auxiliary lines. By displaying the trailer hook and target auxiliary lines on the vehicle's display screen, the driver can determine the position of the trailer hook in the vehicle during reversing, thereby quickly and accurately aligning and connecting the vehicle's trailer hook with the trailer's connecting device.

[0121] Exemplarily, the display screen may be a dashboard, a central control screen, a head-up display screen, etc. of the vehicle. The display screen may be determined based on actual conditions and is not specifically limited here.

[0122] The above technical solution determines the current gear position of the vehicle in response to the start instruction of the trailer function in the vehicle. If the current gear position is in reverse gear, the target auxiliary line of the trailer hook is obtained based on the reversing auxiliary line of the vehicle and the target position of the trailer hook. The target auxiliary line indicates the moving trajectory of the trailer hook, and the target panoramic image is displayed on the display screen of the vehicle. Since the target panoramic image includes the trailer hook and the target auxiliary line, compared with estimating the moving direction and position of the trailer hook in the vehicle through the reversing auxiliary line, the present application determines the target auxiliary line of the trailer hook through the reversing auxiliary line and the target position of the trailer hook, and displays the target auxiliary line and the trailer hook on the display screen. It can accurately locate the moving trajectory and position of the trailer hook during the connection process between the vehicle and the trailer, thereby accurately aligning the connecting device of the trailer hook with the trailer, avoiding collision between the trailer hook and the trailer, improving the convenience of connecting the vehicle to the trailer, and thus improving the safety of the vehicle.

[0123] Figure 4 It is a schematic flow chart of another vehicle display method provided in an embodiment of the present application.

[0124] For example, Figure 4 The method shown can be executed by the vehicle's panoramic monitoring imaging system, vehicle controller or chip.

[0125] For example, Figure 4 As shown, the method 400 includes the following processes:

[0126] S410, in response to a start instruction of a trailer function in the vehicle, determining a current gear position of the vehicle.

[0127] Exemplarily, it is determined whether the trailer function in the vehicle is turned on. In response to an instruction to turn on the trailer function in the vehicle, the trailer hook of the vehicle is controlled to be in an extended state, so that the trailer hook can be coupled with the trailer at any time; in response to an instruction to turn off the trailer function in the vehicle, the trailer hook of the vehicle is controlled to be in a retracted state.

[0128] Optionally, the vehicle trailer function activation instruction can be determined by monitoring the vehicle trailer control; or, the vehicle trailer function activation instruction can be determined by recognizing a voice instruction. The vehicle trailer function activation instruction can be determined according to actual conditions and is not specifically limited here.

[0129] Exemplarily, in response to an instruction to turn on the trailer function in the vehicle, the current gear position of the vehicle is determined. Specifically, when the trailer function in the vehicle is turned on, the trailer hook in the vehicle is controlled to be in an unfolded state, and the current gear position of the vehicle is determined. The trailer hook in the vehicle is installed at the rear of the vehicle. When the vehicle is in reverse gear, it is determined that the vehicle needs to be connected to a trailer. Therefore, whether the vehicle needs to be connected to a trailer can be determined by the current gear position of the vehicle.

[0130] Optionally, the current gear of the vehicle may be forward gear, reverse gear, neutral gear, etc.

[0131] S420, if the vehicle is in reverse gear, determine whether the vehicle and the trailer are in a coupled state; if so, execute S430; if not, execute S440.

[0132] Exemplarily, when the current gear of the vehicle is in reverse gear, it is determined whether the vehicle and the trailer are in a coupled state, and then based on whether the vehicle and the trailer are in a coupled state, it is determined whether the vehicle needs to display the target panoramic image.

[0133] Exemplarily, the coupling state is used to indicate whether the vehicle is successfully connected to the trailer, and the image displayed on the display screen is determined by whether the vehicle is successfully connected to the trailer.

[0134] S430, displaying an initial panoramic image on a display screen of the vehicle.

[0135] Exemplarily, when the vehicle's current gear is in reverse gear, it is determined whether the vehicle and the trailer are in a coupled state. When the vehicle and the trailer hook are in a coupled state, an initial panoramic image is displayed on the vehicle's display screen. The initial panoramic image includes a reversing auxiliary line, but does not include a target auxiliary line of the trailer hook.

[0136] It can be understood that the coupling status is used to indicate that the vehicle is successfully connected to the trailer, that is, the vehicle is successfully connected to the trailer through the connecting device of the trailer hook. In this case, there is no need to display the position of the trailer hook and the target auxiliary line of the trailer hook. It is only necessary to display the initial panoramic image that does not include the target auxiliary line of the trailer hook and includes the reversing auxiliary line.

[0137] S440, determining a target position of the trailer hook on the rear bumper of the vehicle.

[0138] Exemplarily, when the vehicle and the trailer are not in a coupled state, a target position of the trailer hook on the rear bumper of the vehicle is determined, and the target position may indicate a middle position, a left position, a right position, etc. of the rear bumper.

[0139] Optionally, the target position of the trailer hook may be determined according to the method in the aforementioned disclosed embodiment, which is not specifically limited herein.

[0140] S450, taking the target position as a starting point, extending the line in the driving direction to obtain an initial auxiliary line.

[0141] Exemplarily, the initial auxiliary line is determined based on the driving direction of the vehicle and the target position of the trailer hook. Specifically, the target position of the trailer hook on the rear bumper of the vehicle is determined, and the target position is used as the starting point to extend the line in the driving direction to obtain the initial auxiliary line.

[0142] S460: Perform parallel processing on the initial auxiliary line based on the reversing auxiliary line to obtain a target auxiliary line.

[0143] Exemplarily, the initial auxiliary line is processed in parallel based on the reversing auxiliary line to obtain the target auxiliary line, so that the target auxiliary line is parallel to the reversing auxiliary line.

[0144] Specifically, the slope of the reversing auxiliary line is determined by a vector analysis algorithm, and the slope of the initial auxiliary line is ensured to be the same as that of the reversing auxiliary line on the same horizontal line. In order to ensure that the slope of the initial auxiliary line and the reversing auxiliary line are the same, the position and angle of the initial auxiliary line are adjusted so that the initial auxiliary line is aligned and parallel to the reversing auxiliary line to obtain the target auxiliary line. In addition, as the angle of the steering wheel changes during the reversing process, the target auxiliary line and the reversing auxiliary line are updated in real time, but the target auxiliary line always remains parallel to the reversing auxiliary line.

[0145] S470: Determine a position to be added in the initial panoramic image based on the target position of the trailer hook.

[0146] It should be noted that there is no order in which steps S450-S460 and step S470 are executed. Steps S450-S460 may be executed first, or step S470 may be executed first; or, steps S450-S460 and step S470 may be executed at the same time, which is not specifically limited here.

[0147] Exemplarily, determine whether there is a trailer hook in the initial panoramic image. If there is a trailer hook in the initial panoramic image, determine the position to be added in the initial panoramic image based on the target position of the trailer hook, that is, map the actual position (target position) of the trailer hook to the initial panoramic image, and determine the position to be added corresponding to the trailer hook; if there is no trailer hook in the initial panoramic image, obtain the reference position of the target object that blocks the trailer hook, and determine the position to be added in the initial panoramic image based on the reference position of the target object and the target position of the trailer hook.

[0148] It should be noted that the position to be added is used to indicate the position of the target position of the trailer hook in the initial panoramic image, that is, the position to be added is the position of the trailer hook in the initial panoramic image.

[0149] S480, taking the position to be added in the initial panoramic image as a starting point, adding a target auxiliary line to obtain a target panoramic image.

[0150] Exemplarily, when there is a trailer hook in the initial panoramic image, the position to be added in the initial panoramic image is used as the starting point to add target auxiliary lines to obtain a target panoramic image; since the position to be added is determined based on the target position of the trailer hook, that is, the position to be added indicates the position of the trailer hook in the initial panoramic image, by using the position to be added in the initial panoramic image as the starting point to add target auxiliary lines, the accuracy of the target auxiliary lines in the target panoramic image can be ensured, thereby improving the convenience of connecting the vehicle and the trailer.

[0151] S490, displaying the target panoramic image on a display screen of the vehicle.

[0152] Exemplarily, the target panoramic image includes a trailer hook and a target auxiliary line. By displaying the trailer hook and the target auxiliary line on the vehicle's display screen, the driver can determine the position of the trailer hook in the vehicle during reversing, thereby quickly and accurately aligning and connecting the vehicle's trailer hook with the trailer's connecting device.

[0153] Exemplarily, the display screen may be a dashboard, a central control screen, a head-up display screen, etc. of the vehicle. The display screen may be determined based on actual conditions and is not specifically limited here.

[0154] The above technical solution determines the current gear position of the vehicle in response to the start instruction of the trailer function in the vehicle. If the current gear position is in reverse gear, the target auxiliary line of the trailer hook is obtained based on the reversing auxiliary line of the vehicle and the target position of the trailer hook. The target auxiliary line indicates the moving trajectory of the trailer hook, and the target panoramic image is displayed on the display screen of the vehicle. Since the target panoramic image includes the trailer hook and the target auxiliary line, compared with estimating the moving direction and position of the trailer hook in the vehicle through the reversing auxiliary line, the present application determines the target auxiliary line of the trailer hook through the reversing auxiliary line and the target position of the trailer hook, and displays the target auxiliary line and the trailer hook on the display screen. It can accurately locate the moving trajectory and position of the trailer hook during the connection process between the vehicle and the trailer, thereby accurately aligning the connecting device of the trailer hook with the trailer, avoiding collision between the trailer hook and the trailer, improving the convenience of connecting the vehicle to the trailer, and thus improving the safety of the vehicle.
