With continued reference to fig. 2, a flow 200 of one embodiment of a method of generating autonomous driving warning information in accordance with the present disclosure is shown. The method for generating the automatic driving early warning information can comprise the following steps:

step 201, acquiring traffic parameters of the automatic driving vehicle and traffic parameters of other traffic participants.

In this embodiment, the executing entity (e.g., server 104 shown in fig. 1) of the method of generating the autonomous driving warning information may obtain the traffic parameters of the autonomous vehicle and the traffic parameters of the other traffic participants. The other traffic parameters described above are in contrast to autonomous vehicles, which may include, but are not limited to, pedestrians, other motor vehicles, riders, and the like. The traffic parameter of the autonomous vehicle may be a traffic-related parameter generated by the autonomous vehicle during operation, such as a position, a shape, speed information, and the like. The traffic parameters of the other traffic participants may be traffic-related parameters generated by the other traffic participants during operation, such as location, shape, category (e.g., pedestrians, other vehicles, or riders), speed information, and the like.

Correspondingly, in this example, the traffic parameter of the autonomous vehicle may be acquired based on a sensor of the autonomous vehicle, and then the traffic parameter is sent to the execution main body by a terminal of the autonomous vehicle, or acquired by a camera, a speed measuring device, a base station, and the like on the road.

Correspondingly, in this example, the traffic parameters of other traffic participants may be acquired based on a camera, a speed measuring device, a nearby base station, and the like, which are disposed on the road.

In one example, the other traffic participants are pedestrians, and the traffic parameters of the other traffic participants can be acquired based on the terminal devices of the other traffic participants. The other traffic participants are automobiles, and the traffic parameters of the other traffic participants can be acquired based on the terminal devices of the other traffic participants.

When the vehicle is in automatic driving, the traffic parameters of other traffic participants are acquired and obtained based on a plurality of sensors and a map, the other traffic participants can be the traffic participants within a certain range from the automatic driving vehicle, and the certain range can be determined according to whether angles influencing normal driving occur or not.

Specifically, data acquired by various sensors and map information are used as input, and the surrounding environment of the automatic driving vehicle is sensed through a series of calculation and processing. It can provide rich information for the downstream, such as the position, shape, category, speed information, and direction of movement of other traffic participants.

It should be noted that the traffic parameter of the autonomous vehicle and the traffic parameters of other traffic participants may be traffic parameters corresponding to a certain time. However, in order to predict the behaviors of other traffic participants, the traffic parameters of other traffic participants in a preset time period before a certain time may be acquired, so as to predict the behaviors of other traffic participants.

In the technical scheme of the disclosure, the acquisition, storage, application and the like of the related traffic parameters are all in accordance with the regulations of related laws and regulations, and do not violate the good customs of the public order.

Step 202, inputting the traffic parameters of other traffic participants into a pre-trained prediction model to obtain a prediction result.

In this embodiment, the executing entity may input the traffic parameters of the other traffic participants into a pre-trained prediction model to obtain a prediction result corresponding to the traffic participation of the other traffic participants. The prediction result can be used for predicting the traffic state that other traffic participants may be in at the next time after a certain time, for example, predicting the behavior type, predicting the track, and the like.

Here, the prediction model may be trained based on traffic parameters of other traffic participants and corresponding behavior labels.

In this embodiment, it may be accurately determined whether the type, the moving direction, the moving speed, and the like of other traffic participants located outside the autonomous vehicle may affect the normal driving of the autonomous vehicle, and when the behavior of other traffic participants may affect the autonomous vehicle and the relative distance between the autonomous vehicle and the other traffic participants is smaller than a preset distance threshold, it is determined that there is a risk of a traffic accident.

And step 203, determining a traffic risk level aiming at the automatic driving vehicle according to the traffic parameters of the automatic driving vehicle, the traffic parameters of other traffic participants and the prediction result.

In the present embodiment, the execution subject may determine the traffic risk level for the autonomous vehicle according to the traffic parameter of the autonomous vehicle, the traffic parameters of other traffic participants, and the prediction result.

In one example, relative traffic parameters between the autonomous vehicle and other traffic participants may be determined based on traffic parameters of the autonomous vehicle and traffic parameters of the other traffic participants; thereafter, a traffic risk level for the autonomous vehicle is determined based on the relative traffic parameters and the prediction result. The relative traffic parameter may be a relative parameter between the autonomous vehicle and the other traffic participant, such as a distance, a relative speed, etc. between the autonomous vehicle and the other traffic participant.

In this embodiment, the method for generating the automatic driving warning information may further include: and setting a first weight of the relative traffic parameter and a weight corresponding to the prediction result. The first weight and the second weight may be set according to the sensitivity of the warning or may be set by a user.

And step 204, generating corresponding early warning information according to the traffic risk level.

In this embodiment, the execution subject may generate the warning information corresponding to the traffic risk level according to the traffic risk level. The early warning information may include early warning types, early warning contents and the like, the early warning types may include ringing, voice reminding, message reminding and the like, and the early warning contents may include possible accidents, suggested change speeds, the suggested change speeds being preset speeds, categories of other traffic participants, prediction results of other traffic participants and the like. The warning information may be used to alert the driver of the autonomous vehicle and/or other traffic participants.

It should be noted that, when the level of the traffic risk level is higher, multiple warning types can be used in combination to realize warning in all directions. Or, the related traffic managers are informed in advance to maintain the traffic conditions in advance so as to reduce the occurrence of accidents.

After generating the warning information, the method of generating the automatic driving warning information may further include: and sending the early warning information to the terminal equipment of the automatic driving vehicle, and reminding the early warning information by the terminal equipment of the automatic driving vehicle, for example, reminding through a display screen on the terminal equipment of the automatic driving vehicle.

In one example, the early warning information is notified to a human-computer interaction device in the autonomous vehicle, and the human-computer interaction device can prompt passengers in forms of characters, voice, whistling and the like, so that the passengers can be well protected from safety and the like.

In addition, the early warning information can be sent to terminal equipment of other traffic parameter persons. Or the execution main body reminds through a loudspeaker on the road without sending early warning information.

It should be noted that after the terminal device of the autonomous vehicle receives the warning information, the speed of the autonomous vehicle may be adjusted to avoid traffic accidents.

The traffic impact level may be used to characterize the impact level of other traffic participants on the normal travel of the autonomous vehicle.

Correspondingly, in this example, determining the traffic influence degree according to the prediction result may include: and determining the traffic influence degree corresponding to the predicted behavior type according to the predicted behavior type included in the prediction result.

In one example, if the predicted behavior type is an accelerated overtaking, the corresponding traffic impact level is determined based on the accelerated overtaking.

It should be noted that the behavior types of other traffic participants in the present embodiment may include normal driving, sudden stop, reverse driving, overtaking, slowing down and slow driving. The corresponding traffic influence degree can be preset according to the possibility of accidents caused by different behavior types.

In one example, the degree of traffic impact corresponding to overtaking is greater than the degree of traffic impact corresponding to slowing down and crawling.

Correspondingly, in this example, determining the traffic influence degree according to the prediction result may include: and determining the traffic influence degree corresponding to the predicted track according to the predicted track included in the prediction result.

In one example, if the predicted trajectory coincides with a preset trajectory, a corresponding traffic influence degree may be determined according to the predicted trajectory.

It should be noted that the preset trajectory is a trajectory that may affect the normal operation of the autonomous vehicle. For example, other traffic participants travel to a preset location in front of the autonomous vehicle, which may be a location where an accident may occur during a period of normal operation of the autonomous vehicle.
