If the V2X wireless signal monitored by the V2X communication device of the vehicle a includes pedestrian information, at this time, the on-board host computer of the vehicle a is controlled to play a video animation including "notice pedestrian" so as to prompt the driver to notice pedestrian.
The prompt information can also be text content including 'pedestrian passing in front'.
According to the technical means, after the pedestrian information transmitted by the V2X communication device is received, the vehicle-mounted host is controlled to send the prompt information for prompting the driver to pay attention to the pedestrian, so that the traffic accident caused by the fact that the driver does not pay attention to the pedestrian is avoided.
S103, judging whether a traffic signal lamp exists in the surrounding environment of the vehicle or not based on the image.
And S104, controlling the speaker outside the vehicle to send out prompt information for prompting pedestrians to pay attention to the vehicle under the condition that a traffic signal lamp exists in the surrounding environment of the vehicle.
For example, the prompt information for prompting the pedestrian to pay attention to the vehicle may be the voice content of "please pay attention to the vehicle".
As can be seen from the above, in the method of the embodiment of the present application, the vehicle wireless communication technology V2X used obtains the road traffic condition through the way that the automobile and the everything are interconnected, and has stronger detection capability through low-delay and high-reliability network connection interaction. According to the method, based on the strong detection capability of the V2X, under the condition that the received V2X wireless signal comprises pedestrian information, the surrounding environment of the vehicle is identified by combining the image, and under the condition that the surrounding environment of the vehicle comprises a traffic signal lamp, the pedestrian is prompted by using the loudspeaker outside the vehicle. The problems that pedestrians in the surrounding environment of the vehicle cannot be identified due to limited identification range or identification blind areas and the like are avoided, and prompt cannot be timely given to the pedestrians in a proper mode.
In some embodiments, the control of the rear display displays a warning message for warning the rear vehicle of pedestrians in the absence of a traffic light in the surroundings of the vehicle.
For example, the prompt information for prompting the rear vehicle to notice the pedestrian may be the text content of "pedestrian passing in front".
For example, the prompt information for prompting the following vehicle to notice the pedestrian may also be a logo image of "notice the pedestrian".
According to the technical means, the vehicle can control the rear display to display the prompt information for prompting the rear vehicle to pay attention to pedestrians under the condition that the traffic signal lamp exists in the surrounding environment of the vehicle, so that the situation that the traffic accident is caused by the fact that the sight of the rear vehicle is blocked is avoided.

And S202, controlling the car lamp system to project a pavement image to the front of the vehicle under the condition that no traffic signal lamp exists in the surrounding environment of the vehicle and the brightness value of the environment is smaller than a threshold value.
The environment light brightness value smaller than the threshold value may be set according to the environment light brightness value when the visible distance in the evening is short, which is not limited in the embodiment of the present application.
Exemplary, the threshold is 100cd/m 2 . No traffic signal lamp exists in the surrounding environment of the vehicle A; the ambient brightness value of the surrounding environment of the vehicle A is 80cd/m 2 That is, the ambient brightness value of the environment around the vehicle a is smaller than the threshold value. At this time, the lamp system is controlled to project a sidewalk image to the front of the vehicle to guide the pedestrian through the road.
As can be seen from the above, in the method provided by the embodiment of the present application, in a low-visible environment where there is no traffic signal lamp around the vehicle and the brightness is low, the pedestrian image is projected to guide the pedestrian, so that the traffic accident caused by the situation that the pedestrian cannot see the road clearly is avoided.
In some embodiments, where no traffic light is present in the vehicle surroundings and the ambient light level is less than the threshold value, the control light system projects an image and/or text to the front left and/or front right of the vehicle to alert the rear vehicle to pedestrians.
Exemplary, the threshold is 100cd/m 2 The prompt information is the text content of pedestrian in front. No traffic signal lamp exists in the surrounding environment of the vehicle A; the ambient brightness value around the vehicle A was 90cd/m 2 That is, the ambient brightness value of the environment around the vehicle a is smaller than the threshold value. At this time, the lamp system is controlled to project the text content of "pedestrian in front" to the left and right front of the vehicle to prompt the following vehicle to pay attention to the pedestrian.
Exemplary, the threshold is 100cd/m 2 The prompt information is the text content of 'noticing pedestrians' and the image content of 'noticing pedestrians' sign. No traffic signal lamp exists in the surrounding environment of the vehicle A; the ambient brightness value around the vehicle A was 40cd/m 2 That is, the ambient brightness value of the environment around the vehicle a is smaller than the threshold value. At this time, controlThe lamp making system projects the text content of pedestrian in front and the image content of pedestrian mark to the right front of the vehicle to prompt the rear vehicle to pay attention to the pedestrian.
As can be seen from the above, in the method provided by the embodiment of the present application, under the condition that there is no traffic signal lamp around the vehicle and the ambient brightness is less than the threshold value, a prompt is given to the rear vehicle in a projection manner, so that traffic accidents caused by that no pedestrian is observed by the rear vehicle are avoided.
In some embodiments, in the case that no traffic signal lamp exists in the surrounding environment and the environmental brightness value is smaller than the threshold value, the shooting device is controlled to identify the position of the pedestrian, and the car lamp system is controlled to illuminate the position of the pedestrian.
According to the technical means, the traffic light is not arranged around the vehicle, and under the condition that the ambient brightness is smaller than the threshold value, the position of the pedestrian is illuminated, so that traffic accidents caused by unclear vision of the pedestrian are avoided.
The above method provided in the embodiment of the present application will be further described below with reference to fig. 4.
