[0034] The following describes exemplary embodiments of the present disclosure with reference to the accompanying drawings. Various details of the embodiments of the present disclosure are included to facilitate understanding, and they should be considered merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, descriptions of well-known functions and structures are omitted below for clarity and conciseness.

[0035] In the technical solution of the present disclosure, the processing of the collection, storage, use, processing, transmission, provision, and disclosure of the user's personal information complies with the provisions of relevant laws and regulations and does not violate public order and good customs.

[0036] Figure 1 An exemplary architecture 100 to which the display method and device for a turn signal applicable to the present disclosure can be applied is shown.

[0037] As Figure 1 shown, the system architecture 100 may include terminal devices 101, 102, 103, a network 104, and a server 105. The terminal devices 101, 102, 103 are communicatively connected to form a topology network, and the network 104 is used as a medium to provide a communication link between the terminal devices 101, 102, 103 and the server 105. The network 104 may include various connection types, such as wired, wireless communication links, or fiber optic cables, etc.

[0038] The terminal devices 101, 102, 103 interact with the server 105 through the network 104 to receive or send messages, etc. The terminal devices 101, 102, 103 may be hardware devices or software that support network connections for data interaction and data processing. When the terminal devices 101, 102, 103 are hardware, they may be various electronic devices that support network connections, information acquisition, interaction, display, processing, etc., including but not limited to in-vehicle computers, smartphones, tablets, e-book readers, laptop computers, and desktop computers, etc. When the terminal devices 101, 102, 103 are software, they may be installed in the above-listed electronic devices. It may be implemented as, for example, multiple software or software modules for providing distributed services, or it may be implemented as a single software or software module. No specific limitation is made here.

[0039] The server 105 may be a server that provides various services. For example, it is a background processing server that generates driving instructions for autonomous vehicle connections based on the traffic environment information collected by autonomous vehicles. When the driving instruction is a vehicle turning instruction, it controls the corresponding turn signal to display the turning pattern corresponding to the turning type represented by the vehicle turning instruction. As an example, the server 105 may be a cloud server.

[0040] It should be noted that the server can be hardware or software. When the server is hardware, it can be implemented as a distributed server cluster composed of multiple servers or as a single server. When the server is software, it can be implemented as multiple software or software modules (such as software or software modules for providing distributed services), or as a single software or software module. No specific limitation is made here.

[0041] It should also be noted that the display method applied to the turn signal provided by the embodiments of the present disclosure can be executed by the server, or by the terminal device, or by the server and the terminal device in cooperation with each other. Correspondingly, each part (such as each unit) included in the display device applied to the turn signal can be all arranged in the server, or all arranged in the terminal device, or respectively arranged in the server and the terminal device.

[0042] It should be understood that Figure 1 the numbers of the terminal devices, the network and the server in

[0043] are merely illustrative. According to the implementation requirements, there can be any number of terminal devices, network and server. When the electronic device on which the display method applied to the turn signal runs does not need to perform data transmission with other electronic devices, the system architecture can only include the electronic device (such as the server or the terminal device) on which the display method applied to the turn signal runs. Figure 2 , Figure 2 Please refer to

[0044] which is a flowchart of a display method applied to a turn signal provided by an embodiment of the present disclosure. Among them, process 200 includes the following steps:

[0045] In this embodiment, the execution subject of the display method applied to the turn signal (such as Figure 1 the terminal device or the server in

[0046] can obtain the vehicle steering instruction from a remote or local location based on a wired network connection method or a wireless network connection method. The vehicle steering instruction can be a steering instruction issued by an autonomous vehicle or a steering instruction issued by a driver based on voice, action, etc. The autonomous vehicle can be an automobile with autonomous driving function and assisted driving function. The autonomous vehicle is also called a driverless vehicle, a computer-driven vehicle or a wheeled mobile robot, which relies on the collaborative cooperation between artificial intelligence, vision computing, radar, monitoring devices and the global positioning system to enable the on-vehicle computer to automatically and safely operate the motor vehicle without any active operation by humans.

[0047] During the driving process of an autonomous vehicle, vehicle steering instructions can be generated based on the collected environmental information, location information, and a pre-set driving path. The vehicle steering instructions include but are not limited to turning instructions, U-turn instructions, and overtaking instructions.

[0048] During the actual operation process, the turning instruction generally indicates that the autonomous vehicle changes its driving direction at a turning angle not greater than 90°; the U-turn instruction generally indicates that the autonomous vehicle changes its driving direction at a turning angle of about 180°; in the case of overtaking in the same lane under the traffic rule of driving on the right, the overtaking instruction generally first indicates that the autonomous vehicle changes lanes to the left lane, and after completing the overtaking process, it then indicates that the autonomous vehicle changes lanes back to the current lane. Of course, under the traffic rule of driving on the left, the overtaking instruction is the opposite of the above situation.

[0049] Step 202: Determine the steering pattern corresponding to the steering type represented by the vehicle steering instruction.

[0050] In this embodiment, the above-mentioned execution entity can determine the steering pattern corresponding to the steering type represented by the vehicle steering instruction.

[0051] The steering types represented by the vehicle steering instructions include but are not limited to steering types such as turning, U-turning, and overtaking. In the turning type, it specifically includes left turning and right turning. In the U-turn type, it is generally a left-turn U-turn. In the overtaking type, it generally includes the following situations: Before overtaking, the current vehicle and the vehicle in front are in the same lane, and the current vehicle needs to change to the overtaking lane. After overtaking is completed, it returns to the original lane; Before overtaking, the current vehicle is already in the overtaking lane different from the vehicle in front. After overtaking is completed, it changes to the lane corresponding to the vehicle in front; Before overtaking, the current vehicle is in a different lane from the vehicle in front. After overtaking is completed, it still drives in the original lane.

[0052] Corresponding to different steering types, corresponding steering patterns are set in the above-mentioned execution entity or an electronic device communicatively connected to the above-mentioned execution entity. The steering patterns of different steering types are different.

[0053] In order to enable the turn signal to clearly display the vehicle's steering intention, the steering pattern is relatively simple, and there are obvious differences between the steering patterns of different steering types. As an example, various steering signs in traffic signs can be referred to to set the steering patterns corresponding to different steering types. Taking turning as an example, its steering pattern is an arrow pattern consistent with the turning direction; taking a U-turn as an example, its steering pattern is a U-turn sign.

[0054] Step 203: Control the turn signal corresponding to the vehicle steering instruction to display the steering pattern.

[0055] In this embodiment, the above-mentioned execution entity can control the turn signal corresponding to the vehicle steering instruction to display the steering pattern.

[0056] The turn signal corresponding to the vehicle steering instruction is the turn signal on the side of the two side turn signals on the autonomous vehicle that indicates the turning direction indicated by the vehicle steering instruction.

[0057] As an example, for a left turn instruction, its corresponding turn signal is the left turn signal; for a right turn instruction, its corresponding turn signal is the right turn signal. Specifically, the left and right sides of the turn signal are distinguished based on the direction of the vehicle head.

[0058] A plurality of light-emitting regions are arranged in the turn signal, and the plurality of light-emitting regions are arranged in an orderly manner. The above-mentioned execution entity controls the light-emitting state of the light-emitting regions to form a steering pattern for display. Specifically, each light-emitting region includes a plurality of light-emitting units, a light guide structure, and a steering electronic control unit that controls the light-emitting units to be lit in an orderly manner.

[0059] As an example, the light-emitting unit can be a light-emitting diode, and the surface is covered with a thick-wall light guide structure to make the entire light-emitting direction controllable and the light output uniform.

[0060] Continue to refer to Figure 3 , Figure 3 FIG. 300 is a schematic diagram of an application scenario of a display method applied to a turn signal according to this embodiment. In the Figure 3 application scenario, during the driving process of the autonomous vehicle, it will turn left at the next intersection according to the preset driving trajectory. Therefore, the on-vehicle computer of the autonomous vehicle generates a left turn instruction 301. After obtaining the vehicle steering instruction of the autonomous vehicle, the on-vehicle computer determines that the steering type represented by the vehicle steering instruction is a left turn, and the corresponding steering pattern 302; finally, it controls the left turn signal of the autonomous vehicle corresponding to the vehicle steering instruction to display the steering pattern, so as to clearly display the turning intention of the autonomous vehicle to surrounding vehicles and pedestrians through the turn signal.

[0061] In this embodiment, a display method applied to a turn signal is provided. According to the vehicle steering instruction of the autonomous vehicle, the corresponding turn signal is controlled to display the steering pattern corresponding to the steering type represented by the vehicle steering instruction, so that the turn signal can more clearly display the turning intention of the vehicle, facilitating surrounding vehicles and pedestrians to accurately understand the turning intention and make response actions in advance, improving traffic safety.

[0062] In some alternative implementation manners of this embodiment, the turn signal includes an H-shaped display structure, and the H-shaped display structure includes at least four independent lamp segments. The display structures in the left and right turn signals of the autonomous vehicle can be symmetrically arranged.

[0063] In this implementation manner, the above-mentioned execution entity can control the lighting sequence of the lamp segments in the H-shaped display structure according to the steering trajectory to display the steering pattern.

[0064] The turn signal can be the front turn signal and / or the rear turn signal of an autonomous vehicle. Given that the rear turn signal has a better display effect, the turn signal in this implementation is generally the rear turn signal of an autonomous vehicle.

[0065] In some examples, the display structure inside the turn signal is an h-shaped display structure arranged on a horizontal plane. Refer to Figure 4A , which shows a schematic diagram of the display structure of the left turn signal of an autonomous vehicle. Among them, the display structure of the left turn signal includes four independent lamp segments 401, 402, 403, and 404. For the convenience of display, the plane height near the rear end of the vehicle is lower than the plane height near the front end of the vehicle.

[0066] Refer to Figure 4B , which shows a schematic diagram of the display structure of the right turn signal of an autonomous vehicle. Among them, the display structure of the right turn signal includes four independent lamp segments 405, 406, 407, and 408.

[0067] Specifically, the position coordinate system of the turn signal in the autonomous vehicle is as Figure 4C shown.

[0068] In some other examples, the display structure inside the turn signal is an h-shaped display structure arranged on a vertical plane. Refer to Figure 5A , which shows a schematic diagram of the display structure of the left turn signal of an autonomous vehicle. Among them, the display structure of the left turn signal includes four independent lamp segments 501, 502, 503, and 504.

[0069] Refer to Figure 5B , which shows a schematic diagram of the display structure of the right turn signal of an autonomous vehicle. Among them, the display structure of the right turn signal includes four independent lamp segments 505, 506, 507, and 508. Specifically, the position coordinate system of the turn signal in the autonomous vehicle is still as Figure 4C shown.

[0070] In this implementation, the turn signal is composed of four independent lamp segments to form an h-shaped display structure, and the left and right turn signals are symmetrically arranged, improving the simplicity and feasibility of the turn signal structure.

[0071] In some alternative implementations of this embodiment, the above-mentioned execution entity can execute the above step 203 in the following manner: control the turn signal corresponding to the vehicle steering instruction to display a steering pattern in a dynamic flowing light manner.

[0072] As an example, the turn signal is provided with a steering electronic control unit for controlling the light-emitting units to light up in an orderly manner. By sequentially lighting up the light-emitting units in different light-emitting areas through the steering electronic control unit, a dynamic flowing light effect is achieved.

[0073] Taking the left-turn arrow in a left-turn scenario as an example, the light-emitting units from the tail to the head of the left-turn arrow can be sequentially lit.

[0074] In this implementation, the steering pattern is displayed by means of dynamic flowing lighting, further improving the display effect of the turn signal and enabling the vehicle's turning intention to be more clearly shown.

[0075] In some alternative implementations of this embodiment, the above-mentioned execution entity may execute the above step 202 in the following manner:

[0076] First, determine the steering trajectory corresponding to the steering type represented by the vehicle steering instruction; second, determine the steering pattern matching the steering trajectory.

[0077] The steering trajectory represents the trajectory of the autonomous vehicle from the steering starting point to the steering ending point during the steering process. In this implementation, the above-mentioned execution entity may generate a steering pattern with reference to the steering trajectory. As an example, for a turning instruction, the steering pattern is composed of a first line segment representing straight travel and a second line segment representing the turning direction. For a U-turn instruction, the steering pattern is composed of a first line segment representing straight travel, a second line segment representing the U-turn direction, and a third line segment representing the driving direction after the U-turn.

[0078] In this embodiment, the steering pattern matches the steering trajectory, and the steering pattern matching the steering trajectory can be directly displayed through the turn signal, enabling the turn signal to more clearly show the vehicle's turning intention and facilitating surrounding vehicles and pedestrians to accurately understand the turning intention.

[0079] In some alternative implementations of this embodiment, the above-mentioned execution entity may execute the above second step in the following manner: in response to determining that the vehicle steering instruction is a turning instruction, determine the steering pattern matching the turning trajectory corresponding to the turning instruction.

[0080] In the horizontal plane structure, referring to Figure 6 , a schematic diagram of the steering pattern corresponding to a left-turn instruction is shown. During the flowing lighting process, the lamp segments 601 and 602 are sequentially lit. Referring to Figure 7 , a schematic diagram of the steering pattern corresponding to a right-turn instruction is shown. During the flowing lighting process, the lamp segments 701 and 702 are sequentially lit.

[0081] In the vertical plane structure, referring to Figure 8 , a schematic diagram of the steering pattern corresponding to a left-turn instruction is shown. During the flowing lighting process, the lamp segments 801 and 802 are sequentially lit. Referring to Figure 9 , a schematic diagram of the steering pattern corresponding to a right-turn instruction is shown. During the flowing lighting process, the lamp segments 901 and 902 are sequentially lit.

[0082] In this implementation, a specific steering pattern in the turning instruction scenario is provided. The turn signal clearly shows the turning intention in the turning scenario, improving traffic safety in the turning scenario.

[0083] In some alternative implementation manners of this embodiment, the above-mentioned execution entity may execute the above-mentioned second step in the following manner: in response to determining that the vehicle steering instruction is a U-turn instruction, determine a steering pattern that matches the U-turn trajectory corresponding to the U-turn instruction.

[0084] In the horizontal plane structure, referring to Figure 10 , a schematic diagram of the steering pattern corresponding to the U-turn instruction is shown. During the sequential lighting process, lamp segments 1001, 1002, and 1003 are sequentially lit.

[0085] In the vertical plane structure, referring to Figure 11 , a schematic diagram of the steering pattern corresponding to the U-turn instruction is shown. During the sequential lighting process, lamp segments 1101, 1102, and 1103 are sequentially lit. It should be noted that in the U-turn scenario, an autonomous vehicle generally turns to the left for a U-turn. When in some special scenarios, the autonomous vehicle turns to the right for a U-turn, its steering pattern is the same as that in the above Figure 10 , 11 , but the lighting sequence of the lamp segments is reversed.

[0086] In this implementation, a steering pattern in the U-turn instruction scenario is provided. The turn signal clearly shows the turning intention in the U-turn scenario, improving traffic safety in the U-turn scenario.

[0087] In some alternative implementation manners of this embodiment, the above-mentioned execution entity may execute the above-mentioned second step in the following manner: in response to determining that the vehicle steering instruction is an overtaking instruction, determine a steering pattern that matches the overtaking trajectory corresponding to the overtaking instruction.

[0088] In the horizontal plane structure, referring to Figure 12 , a schematic diagram of the steering pattern corresponding to the left lane change situation is shown. During the sequential lighting effect, lamp segments 1201, 1202, and 1203 are sequentially lit. Referring to Figure 13 , a schematic diagram of the steering pattern corresponding to the right lane change situation is shown. During the sequential lighting effect, lamp segments 1301, 1302, and 1303 are sequentially lit.

[0089] In the vertical plane structure, referring to Figure 14 , a schematic diagram of the steering pattern corresponding to the left lane change situation is shown. During the sequential lighting effect, lamp segments 1401, 1402, and 1403 are sequentially lit. Referring to Figure 15, a schematic diagram showing a steering pattern corresponding to a right lane change situation. In the flowing light effect, the light segments 1501, 1502, and 1503 are lit in sequence.

[0090] For the overtaking situation where, before overtaking, the current vehicle and the vehicle in front are in the same lane, the current vehicle needs to change to the overtaking lane to overtake, and after overtaking is completed, return to the original lane. During the process of the current vehicle changing to the overtaking lane, display Figure 12 the display pattern shown in or 14; when returning to the original lane after overtaking is completed, display Figure 13 the display pattern shown in or 15.

[0091] In this implementation, a steering pattern in the overtaking instruction scenario is provided, and the turn signal clearly shows the steering intention in the overtaking scenario, improving traffic safety in the overtaking scenario.

[0092] Continue to refer to Figure 16 , which shows a schematic flow 1600 of another embodiment of the display method applied to a turn signal according to the present disclosure, including the following steps:

[0093] Step 1601, obtain a vehicle steering instruction.

[0094] Step 1602, determine the steering trajectory corresponding to the steering type represented by the vehicle steering instruction.

[0095] Step 1603, in response to determining that the vehicle steering instruction is a turning instruction, determine a steering pattern that matches the turning trajectory corresponding to the turning instruction.

[0096] Step 1604, in response to determining that the vehicle steering instruction is a U-turn instruction, determine a steering pattern that matches the U-turn trajectory corresponding to the U-turn instruction.

[0097] Step 1605, in response to determining that the vehicle steering instruction is an overtaking instruction, determine a steering pattern that matches the overtaking trajectory corresponding to the overtaking instruction.

[0098] Step 1606, control the turn signal corresponding to the vehicle steering instruction to display the steering pattern in a dynamic flowing light manner.

[0099] It can be seen from this embodiment that compared with the Figure 2 corresponding embodiment, the flow 1600 of the display method applied to the turn signal in this embodiment specifically describes the process of determining the steering pattern under the turning instruction, U-turn instruction, and overtaking instruction, as well as the process of displaying the steering pattern in a dynamic flowing light manner, enabling the turn signal to more clearly display the steering intention of the vehicle, facilitating surrounding vehicles and pedestrians to accurately understand the steering intention and make response actions in advance, and improving traffic safety.
