Background

With the development of society and the advancement of technology, smart vehicles are gradually entering the daily lives of people. Since the smart car has a variety and variability of running environments (e.g., changes in behavior of surrounding vehicles) faced by the smart car during running, more and more sensors are installed on the smart car to sense the changes in behavior of the surrounding vehicles.

Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

Fig. 1 illustrates a schematic diagram of an application scenario 100 to which the control method provided in the embodiment of the present application is applied. As shown in fig. 1, the control method provided by the embodiment of the present application may be applied to an application scenario in which at least one first terminal (the first terminal 110 is shown in fig. 1) performs a warning on the second terminal 120 through a flashing behavior and/or a whistling behavior in unmanned driving, autonomous driving, smart driving, or internet driving.

Alternatively, the first terminal 110 may be a motor vehicle (e.g., an unmanned vehicle, a smart car, an electric vehicle, a digital car, etc.), an unmanned plane, a rail car, or a traffic light, etc., and may be a terminal capable of emitting lights and/or whistling sounds to the outside.

Alternatively, the second terminal 120 may be a motor vehicle (e.g., an unmanned vehicle, a smart car, an electric vehicle, a digital car, etc.), an unmanned plane, a rail car, a bicycle, a traffic light, etc., and a terminal capable of receiving lights and/or whistling sounds emitted from the outside.

In a possible implementation manner, the distance between the first terminal 110 and the second terminal 120 may be smaller than a preset first threshold, that is, the first terminal 110 may be located within a range centered on the second terminal 120 and taking the first threshold as a radius.

In other words, the first terminal 110 may be located near the second terminal 120, such as where the lights of the first terminal 110 may be observed and/or the whistle of the first terminal 110 may be received at the location of the second terminal 120.

For example: the first terminal 110 drives behind the second terminal 120, and if the first terminal 110 finds an abnormal situation such as the trunk of the second terminal 120 is not closed, the first terminal 110 may alert the second terminal 120 by whistling.

For another example: in some sections where whistling is prohibited, if the first terminal 110 wants to exceed the second terminal 120, the first terminal 110 may alert the second terminal by turning on the left turn light.

Taking the first terminal 110 as the vehicle 1 and the second terminal 120 as the vehicle 2 as an example, in the prior art, the vehicle 2 may detect the light and/or the whistle of the external vehicle through various sensors mounted on the vehicle, and remind the vehicle owner of the flashing behavior and/or the whistle behavior of the vehicle 1, however, there is a situation that the vehicle owner of the vehicle 2 does not notice the light and/or the whistle of the external vehicle 1 during the driving process (for example, the vehicle owner of the vehicle 2 does not notice the light of the vehicle 1 by lowering the head of the air conditioner, or the vehicle owner does not notice the whistle of the vehicle 1 due to an active noise reduction function inside the vehicle), in the above situation, the vehicle owner may not timely acquire the reminder of the vehicle 1, and thus, the driving safety is poor.

It should be noted that, in the embodiment of the present application, only the first terminal 110 is used for performing an application scenario of reminding the second terminal 120 through a flashing behavior and/or a whistling behavior, but the embodiment of the present application is not limited thereto.

Optionally, the embodiment of the present application may also be applied to an application scenario in which the first terminal 110 reminds the second terminal through other behaviors, for example, the first terminal 110 reminds the second terminal 120 through a speed change (including speed increase or speed decrease) behavior, a lane change behavior, a docking behavior, and the like, and the application scenario reminded through other behaviors may refer to an application scenario reminded through a flashing behavior and/or a whistling behavior.

The central control device 230 is configured to obtain first behavior indication data of the first terminal, where the first behavior indication data is used to indicate a first behavior of the first terminal, and the first behavior may include a flashing light behavior and/or a whistling behavior; determining a first behavioral goal for the first behavior based on the first behavior indicating data; and controlling the second terminal to perform a first operation in response to the first behavioral goal.

For example: the central control device 230 may be a central control system.

It should be noted that, since the flashing behavior purpose represented by different positions, colors, flashing frequencies and/or flashing times of the lights of the first terminal may be different, and similarly, the whistle behavior represented by different directions, lengths, frequencies and/or flashing times of the whistle sounds of the first terminal may also be different, the central control device may comprehensively analyze and judge the first behavior purpose of the first terminal based on the flashing behavior and/or the whistle behavior of the first terminal.

Optionally, the first operation may include at least one of a vehicle speed control operation (such as a braking operation, a starting operation, an accelerating operation or a decelerating operation), a flashing operation, a whistle operation, and a lane changing operation, which is not limited in the embodiment of the present application.

In another possible implementation, the central control device 230 may communicate with the image capturing device 210 (or the audio capturing device 220) in a wireless manner.
