Accordingly, the display device applied to the turn signal lamp may include all of the parts (e.g., the units) provided in the server, all of the parts provided in the terminal device, and both of the parts provided in the server and the terminal device.

It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for an implementation. When the electronic device on which the display method applied to the turn signal lamp is operated does not need to perform data transmission with other electronic devices, the system architecture may include only the electronic device (e.g., a server or a terminal device) on which the display method applied to the turn signal lamp is operated.

Referring to fig. 2, fig. 2 is a flowchart of a display method applied to a turn signal lamp according to an embodiment of the disclosure, wherein the process 200 includes the following steps:

step 201, a vehicle steering command is acquired.

In this embodiment, an execution subject (for example, a terminal device or a server in fig. 1) of the display method applied to the turn signal lamp may obtain the vehicle turn command from a remote location or a local location based on a wired network connection manner or a wireless network connection manner.

The vehicle steering command may be a steering command issued by the autonomous vehicle, or may be a steering command issued by the driver based on voice, motion, or the like. The autonomous vehicle may be an automobile having an autonomous driving function and a driving assistance function. An autonomous vehicle, also known as an unmanned vehicle, a computer-driven vehicle or a wheeled mobile robot, relies on the cooperative cooperation between artificial intelligence, visual computing, radar, monitoring devices and a global positioning system to allow the onboard computer to operate the motor vehicle automatically and safely without any human active operation.

During the driving process of the automatic driving automobile, a vehicle steering instruction can be generated according to the collected environment information, the collected position information and the preset driving path. The vehicle steering command includes, but is not limited to, a turn command, and an overtaking command.

During actual operation, turn commands typically instruct an autonomous vehicle to change its direction of travel at a turn angle of no more than 90 °; turn-around commands typically instruct an autonomous vehicle to change its direction of travel by a turn angle of about 180 degrees; under the traffic rule of driving on the right, for the overtaking condition of the same lane, the overtaking instruction generally indicates the automatic driving vehicle to turn to the left lane at first, and then indicates the automatic driving vehicle to turn to the current lane after the overtaking process is finished. Of course, in the traffic law of left-hand driving, the overtaking command is the opposite of the above.

Step 202, determining a steering pattern corresponding to the steering type represented by the vehicle steering command.

In this embodiment, the executing entity may determine a steering pattern corresponding to a steering type represented by the vehicle steering command.

The type of steering characterized by the vehicle steering command includes, but is not limited to, turning, overtaking, etc. Among the types of turning, left and right turning are specifically included. In the turn-around type, turning around to the left side is common. The following situations are generally included in the type of overtaking: before overtaking, the current vehicle and the front vehicle are in the same lane, the current vehicle needs to be changed to the overtaking lane, and the current vehicle returns to the original lane after overtaking is finished; before overtaking, the current vehicle is positioned in a overtaking lane different from the lane of the previous vehicle, and after overtaking is finished, the current vehicle is switched to the lane corresponding to the previous vehicle; before overtaking, the current vehicle and the previous vehicle are in different lanes, and after overtaking is finished, the current vehicle still runs in the original lane.

Corresponding steering patterns are arranged in the execution main body or the electronic equipment which is in communication connection with the execution main body corresponding to different steering types. The steering patterns differ for different steering types.

In order to enable the steering lamp to clearly display the steering intention of the vehicle, the steering pattern is concise, and the steering patterns of different steering types are obviously different. As an example, a steering pattern corresponding to different steering types may be set with reference to various steering flags in the traffic sign. Taking a turn as an example, the turning pattern is an arrow pattern which is consistent with the turning direction; taking turn around as an example, the turning pattern is a turn around mark.

And step 203, controlling a steering lamp corresponding to the vehicle steering command to display a steering pattern.

In this embodiment, the executing body may control a turn light corresponding to the vehicle steering command to display a steering pattern.

The turn signal corresponding to the vehicle turn instruction is the turn signal on one side of the turning direction indicated by the vehicle turn instruction in the two side turn signals on the automatic driving vehicle.

As an example, for a left turn command, its corresponding turn signal is the left turn signal; for a right turn command, the corresponding turn signal is the turn signal on the right side. Specifically, the left side and the right side of the steering lamp are distinguished by taking the direction of the vehicle head as a reference.

A plurality of light-emitting areas are arranged in the turn light and are orderly arranged. The execution main body performs display by controlling the light emitting state of the light emitting region to form a turning pattern. Specifically, each light-emitting area comprises a plurality of light-emitting units, a light guide structure and a steering electric control unit for controlling the light-emitting units to be sequentially lightened.

By way of example, the light emitting unit may be a light emitting diode, and the surface of the light guiding structure is covered with a thick wall, so that the whole light emitting direction can be controlled and the light can be emitted uniformly.

With continued reference to fig. 3, fig. 3 is a schematic diagram 300 of an application scenario of the display method applied to the turn signal lamp according to the present embodiment. In the application scenario of fig. 3, the autonomous vehicle will turn left at the next intersection according to the preset driving trajectory during driving, and then the onboard computer of the autonomous vehicle generates a left turn command 301. After a vehicle steering command of the automatic driving vehicle is obtained, the vehicle-mounted computer determines that the steering type represented by the vehicle steering command is a left turn and a steering pattern 302 corresponding to the steering type; and finally, controlling a left turn lamp of the automatic driving vehicle corresponding to the vehicle turning instruction to display a turning pattern so as to clearly display the turning intention of the automatic driving vehicle to surrounding vehicles and pedestrians through the turn lamp.

In the embodiment, the display method applied to the steering lamp is provided, and according to the vehicle steering instruction of the automatic driving vehicle, the corresponding steering lamp is controlled to display the steering pattern corresponding to the steering type represented by the vehicle steering instruction, so that the steering lamp can more clearly display the steering intention of the vehicle, surrounding vehicles and pedestrians can accurately understand the steering intention, a response action is made in advance, and the traffic safety is improved.

In some optional implementations of this embodiment, the turn signal includes an h-shaped display structure, the h-shaped display structure includes at least four independent light segments, and the display structures in the left and right turn signals of the autonomous vehicle may be symmetrically arranged.

In this implementation, the executing body may control the lighting sequence of the light segments in the h-shaped display structure according to the steering track, so as to display the steering pattern.

The turn signal may be a front turn signal and/or a rear turn signal of the autonomous vehicle. The turn signal in this implementation is typically the rear turn signal of an autonomous vehicle, in view of the better display effect of the rear turn signal.

In some examples, the display structure within the turn signal is an h-shaped display structure disposed on a horizontal plane. Referring to fig. 4A, a display configuration diagram of a left turn light of an autonomous vehicle is shown. The display structure of the left turn light comprises four independent

light segments

401, 402, 403 and 404. For convenience of display, the height of the plane adjacent to the tail end of the vehicle is lower than the height of the plane adjacent to the head end of the vehicle.

Referring to fig. 4B, a display configuration diagram of a right turn light of an autonomous vehicle is shown. Wherein the display structure of the right turn light comprises four

separate light segments

405, 406, 407 and 408.

Specifically, the position coordinate system of the turn signal in the autonomous vehicle is shown in fig. 4C.

In other examples, the display structure within the turn signal is an h-shaped display structure disposed on a vertical plane. Referring to fig. 5A, a display configuration diagram of a left turn light of an autonomous vehicle is shown. The display structure of the left turn light comprises four independent

light segments

501, 502, 503 and 504.

Referring to fig. 5B, a display configuration diagram of a right turn light of an autonomous vehicle is shown. Wherein the display structure of the right turn light comprises four

separate light segments

505, 506, 507 and 508. Specifically, the position coordinate system of the turn signal in the autonomous vehicle is still as shown in fig. 4C.

In the implementation mode, the steering lamp forms an h-shaped display structure based on four independent lamp sections, the left steering lamp and the right steering lamp are symmetrically arranged, and the simplicity and the feasibility of the steering lamp structure are improved.

In some optional implementations of this embodiment, the executing main body may execute the step 203 by: and controlling a steering lamp corresponding to the vehicle steering command, and displaying a steering pattern in a dynamic running water lighting mode.

By way of example, the steering lamp is provided with a steering electronic control unit which controls the light-emitting units to be sequentially lightened, and the light-emitting units in different light-emitting areas are sequentially lightened by the steering electronic control unit, so that a dynamic running water lightening effect is achieved.

Taking a left-turn arrow in a left-turn scene as an example, the light emitting units from the tail of the left-turn arrow to the head of the left-turn arrow may be sequentially lit.

In the implementation mode, the steering patterns are displayed in a dynamic running water lighting mode, the display effect of the steering lamp is further improved, and the steering intention of the vehicle can be displayed more clearly.

In some optional implementations of this embodiment, the executing main body may execute the step 202 by:

firstly, determining a steering track corresponding to a steering type represented by a vehicle steering command; second, a steering pattern matching the steering trajectory is determined.

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 execution body may generate the steering pattern with reference to the steering trajectory. As an example, for a turn command, the steering pattern is made up of a first line segment characterizing straight travel and a second line segment characterizing turn direction. For a turn command, the steering pattern is composed of a first line segment representing straight traveling, a second line segment representing a turn direction, and a third line segment representing a driving direction after turning.

In this embodiment, turn to the pattern and turn to the orbit phase-match, can directly show through the indicator and turn to the pattern that the orbit matches for the indicator can show the intention of turning to of vehicle more clearly, is convenient for surrounding vehicle and pedestrian accurately understand the intention of turning to.

In some optional implementations of this embodiment, the executing body may execute the second step by: in response to determining that the vehicle steering command is a turn command, a steering pattern that matches a turn trajectory corresponding to the turn command is determined.

lamp segments

1101, 1102, 1103 are sequentially lighted. It should be noted that, in a turning scene, the autonomous vehicle generally turns around to the left, and in some special scenes, the steering pattern of the autonomous vehicle turns around to the right is the same as the steering pattern in fig. 10 and 11, except that the lighting sequence of the light segments is reversed.

In the implementation mode, the steering pattern under the turning instruction scene is provided, the steering intention under the turning scene is clearly displayed by the steering lamp, and the traffic safety under the turning scene is improved.
