Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
The number of vehicles running on a road is large, the characters of vehicle drivers are different, behaviors are different, and driving operations executed by the vehicles are different. When the automatic driving vehicle interacts with other vehicles, the driving operation of the automatic driving vehicle needs to be reasonably decided, and the intention of the automatic driving vehicle needs to be clearly expressed so as to avoid the misjudgment of the automatic driving vehicle by other vehicles. In addition, the autonomous driving vehicle also needs to prompt abnormal driving operations of other vehicles in time, thereby reducing risk factors.
The current automated driving scheme focuses on decision-making, planning and control of driving operations inherent in an automated driving vehicle, so that the automated driving vehicle can safely and effectively run under different road conditions. However, these driving operations are not transparent to other vehicles, and thus a misunderstanding is inevitably generated.
For example, the heavy-duty trailer is large in size and relatively slow in lane changing process, and a vehicle located behind the heavy-duty trailer may understand that the heavy-duty trailer slowly changes lanes as avoiding of the vehicle behind the heavy-duty trailer, and then the vehicle runs fast in a target lane of the heavy-duty trailer, so that the vehicle behind the heavy-duty trailer may collide with the heavy-duty trailer, and a large potential safety hazard is caused. Alternatively, the driver may cause the vehicle to deviate from the center of the lane due to fatigue driving, or to travel slowly in a fast lane, or to attempt to forcibly cut in front of the autonomous vehicle. At the moment, the automatic driving vehicle needs to give a prompt in time to warn the vehicle, so that risk factors are avoided. Furthermore, autonomous vehicles, particularly heavy trucks, may affect the field of view of other vehicles, and if the autonomous vehicle is able to give the necessary reminders to other vehicles with a obscured field of view, the other vehicles' understanding of the behavior of the autonomous vehicle can be enhanced.
In order to solve the above problems, it is necessary for an autonomous vehicle to actively interact with other vehicles by comprehensively using various means. This interaction is both an explicit expression of the ideas, plans, and actions of the autonomous vehicle, and an intention to assist other vehicles in understanding the surrounding situation and the autonomous vehicle.
In the related scheme, the vehicle usually adopts a passive response type interactive mode, for example, other vehicles forcibly pass through a target lane of the vehicle in the lane changing process, the vehicle passively cancels the lane changing, and a turn lamp is turned off to ensure safety, but necessary reminding and warning are not actively performed on other vehicles before canceling the lane changing. When the vehicle runs at risk at the other side, the vehicle often needs to borrow the lane from the other side or even change the lane to avoid the risk. At this time, a general scheme is to turn on a turn signal and wait for a lane change time, but the vehicle in a target lane usually ignores the turn signal of the vehicle and does not avoid the vehicle because the motive of the vehicle is not understood, so that the vehicle cannot avoid the risk in time.
In summary, most of the current implementation schemes for interacting with other vehicles are passive response type, and the current field of automatic driving lacks an overall scheme for systematically interacting with other vehicles.
In the embodiment of the application, a systematic solution is provided for the active interaction problem between the autonomous driving vehicle and other intelligent agents in the environment in the driving process. The intelligent body comprises all the individuals or groups with intelligence and capable of making decisions and actions according to various perception information. For example, an agent in a traffic environment is mainly a human being, and includes a driver, a pedestrian, an engineering worker, a service person in a specific scene, and the like, and may further include other autonomous vehicles.
The difference in behavior of a common vehicle mainly means that drivers driving the vehicle have different ideas, different driving powers, and different performances of the vehicle. And special vehicles, engineering operators and scene-specific service personnel often have special behavior patterns and specifications. While pedestrian behavior is more random than other human agents. In general, human behavior is generally predictable, while other autonomous vehicle behaviors can vary greatly.
To solve the problem of active interaction with other agents, the following sub-problems need to be solved: (1) what timing to interact; (2) who interacted with; (3) how to interact; (4) how to process the feedback after the interaction. A solution to the above problem will be specifically developed later.
Referring to fig. 1, the active interaction process proposed in the embodiment of the present application includes the following steps:
(1) identifying surrounding agents
In the embodiment of the application, the automatic driving vehicle can identify surrounding intelligent agents by utilizing intelligent agent classification and abnormal behavior discrimination, so as to guide the active interaction process. Different classes of agents have different behavior capabilities and behavior patterns, and behaviors that exceed their general capabilities and patterns are abnormal behaviors.
As shown in fig. 2, the flow of identifying surrounding agents is that an autonomous vehicle collects multi-sensor information via a plurality of sensors arranged, identifies obstacles based on the multi-sensor information, can identify nearby obstacles, classifies the identified obstacles using an agent classification technique to determine the types of agents existing around the vehicle, and then tracks the agents, predicts the behavior of the agents, and identifies whether the agents are abnormal behavior based on the behavior of the agents.
(2) Assessing environmental risks
The process of evaluating the environmental risk is shown in fig. 3, the automatic driving vehicle collects environmental information through multiple sensors, so that a current road structure is obtained, the road structure is reconstructed, and a passable road area is determined by using the reconstructed road structure. And determining an area with a current road structure inconsistent with a known road structure, carrying out scene identification on the area, determining scenes of the area, such as a construction scene, a vehicle fault scene, a road shielding scene and the like, and evaluating the traffic risk of the area.
(3) Selecting interaction opportunities
The autonomous vehicle detects the state of the autonomous vehicle or the state of other agents and selects an appropriate interaction opportunity based on the detected state information.
(4) And (3) scheduling interaction means: the autonomous vehicle is equipped with an output device including at least one of a display screen, a speaker, a siren, or a warning light. The autonomous vehicle outputs information matching the type of state of the autonomous vehicle via a configured output device.
(5) And (3) collecting interactive feedback: the other agents can feed back the driving operation of the automatic driving vehicle, and the automatic driving vehicle collects the information of the other agents through the configured multiple sensors, so that the behaviors of the other agents are determined.
(6) Adjusting the autonomous vehicle behavior: the autonomous vehicle replans its operation based on the detected behavior of the other agents. The autonomous vehicle performs a parking operation or deceleration avoidance, for example, when the autonomous vehicle detects that other agents occupy the lane of the autonomous vehicle.
As shown in fig. 1, through the identification of surrounding agents, the assessment of environmental risks, the autonomous vehicle has a complete understanding of the environmental conditions, and then how to interact with other agents by active interaction means. The active interactive process includes several steps of selecting interactive time, dispatching interactive means, collecting interactive feedback and regulating automatic driving vehicle behavior. The application divides the interaction opportunity into five categories: a) prompting a state of the autonomous vehicle; b) avoiding special vehicles; c) avoiding a dangerous environment; d) the risk of meeting is reduced; e) and an abnormal intelligent agent is warned, and different interaction occasions can occur simultaneously. The active interaction process at different occasions will be explained separately later.
The first interaction mode is as follows: the status of the autonomous vehicle is prompted.
FIG. 4 is a flow chart illustrating a status prompting method, according to an exemplary embodiment, for use with an autonomous vehicle, as shown in FIG. 4, the method comprising:
401. the autonomous vehicle detects current state information of the autonomous vehicle in real time.
In the embodiment of the application, the automatic driving vehicle detects the current state information of the automatic driving vehicle in real time, further determines the state type of the automatic driving vehicle according to the state information, and outputs the prompt information corresponding to the state type according to the state type.
Autonomous vehicles may include, among other vehicles, autonomous cars, autonomous trucks, autonomous motorcycles, and the like.
The state information of the autonomous vehicle is used to indicate a state of the autonomous vehicle. The status information includes a running speed, a running distance, a remaining oil amount, an operation status of each component, an on-off status of a warning lamp, and the like of the autonomous vehicle.
The parts in the automatic driving vehicle comprise an engine, a chassis and vehicle body accessories, wherein the vehicle body accessories comprise a vehicle networking wireless device, a sound receiver, a mechanical whistle or an electronic whistle, an oil tank, tires, a vehicle shell, a vehicle door, vehicle glass, a vehicle mirror, a license plate frame, a seat and seat accessory, a vehicle bearing, an armrest, a handle, a cab and cab accessory, an air bag, a safety belt, a glass lifter, an antenna, a windscreen wiper, a silencer, a loudspeaker, a vehicle sealing strip bumper, a luggage box, an exhaust pipe and the like. Autonomous vehicles may detect the operating status of various components.
The combination of a software system and a hardware system is required for realizing automatic driving of the automatic driving vehicle, and the software system comprises a sensing module, a positioning module and a decision module. The sensing module and the positioning module identify and classify other intelligent agents, the decision-making module judges whether the other intelligent agents are special vehicles or not, meet with automatic driving vehicles or not, and are abnormal or not according to the behaviors of the other intelligent agents, and then the other intelligent agents are interacted by an active interaction means. The hardware system includes components equipped with the autonomous vehicle for interacting with other agents, including warning lights, sirens, display screens, speakers, internet-of-vehicles wireless devices, and the like.
402. The autonomous vehicle determines a status type to which the status information belongs.
And the automatic driving vehicle determines whether the automatic driving vehicle has automatic driving capability and side parking capability according to each detected state information, and further determines the state type of the automatic driving vehicle, so that prompt information corresponding to the state type is output through an output device of the automatic driving vehicle.
In one possible implementation, the condition that the state information should satisfy when the autonomous vehicle has the autonomous driving capability is preset by the autonomous vehicle, and when the autonomous vehicle detects the state information, whether the state information satisfies the preset condition is determined, and then whether the autonomous vehicle has the autonomous driving capability is determined. For example, if the autonomous vehicle is set in advance under the door closing condition and the autonomous vehicle has the autonomous capability, the autonomous vehicle detects the state information of the autonomous vehicle, detects that the door of the autonomous vehicle is not closed, and determines that the autonomous vehicle does not have the autonomous capability because the predetermined condition is not satisfied.
The side parking capability refers to the capability of the autonomous vehicle to park after the autonomous vehicle is able to travel from the current position to the edge of the current road, for example, the autonomous vehicle may travel a short distance to the edge of the current road in a lane located on one side of the road. Alternatively, the autonomous vehicle is currently located in a lane in the middle of the road, and a lane change operation may be performed so as to reach the edge of the current road.
The automatic driving vehicle presets the condition that the state information should meet when having the ability to stop at the side, detects the state information, judges whether the state information meets the preset condition, and then determines whether the automatic driving vehicle has the ability to stop at the side. For example, when the automatic driving vehicle is preset that the remaining amount of fuel is not less than the first preset threshold but not more than the second preset threshold, the automatic driving vehicle has the parking near capability but does not have the automatic driving capability, the automatic driving vehicle detects the state information of the automatic driving vehicle, detects that the remaining amount of fuel of the automatic driving vehicle is less than the first preset threshold, and does not satisfy the preset condition, and thus determines that the automatic driving vehicle does not have the parking near capability.
The automatic driving vehicle divides the state types of the automatic driving vehicle into a normal state type, a first fault state type and a second fault state type according to whether the automatic driving vehicle has automatic driving capability and whether the automatic driving vehicle has the capability of parking at the side.
The normal state type indicates that the autonomous vehicle has no fault and can continue to travel without intervening in the driving operation of the autonomous vehicle. When the state information indicates that the autonomous vehicle has the autonomous driving capability, the state type is determined to be a normal state type.
The first fault status type indicates that the autonomous vehicle has a primary fault that may affect normal driving of the autonomous vehicle, but may still be parked alongside. And when the state information indicates that the automatic driving vehicle does not have the automatic driving capability but has the side parking capability, determining that the state type is the first fault state type.
The second fault status type indicates that the autonomous vehicle has a relatively severe fault and does not have the ability to park while leaning. And when the state information indicates that the automatic driving vehicle does not have the automatic driving capability and the side parking capability, determining that the state type is a second fault state type.
It should be noted that, in the embodiment of the present application, the status types are only divided into the normal status type, the first failure status type and the second failure status type according to whether the autonomous vehicle has the autonomous driving capability and the parking capability, and in another embodiment, the status types may be further divided according to other criteria.
It should be noted that in the embodiment of the present application, it is determined whether the autonomous vehicle has the autonomous driving capability and the side parking capability only by using the state information of the autonomous vehicle, and then the state type of the autonomous vehicle is determined, and in another embodiment, the state type of the autonomous vehicle may be determined by using another method.
The status information may include information in multiple dimensions, such as travel speed, opening and closing states of doors, temperature of the vehicle, and the like. In one possible implementation manner, the autonomous driving vehicle establishes a corresponding relationship between state information of multiple dimensions and a state type, and when any state information is acquired, the corresponding relationship is queried to acquire the state type corresponding to the state information.
The automatic driving vehicle establishes priorities of a normal state type, a first fault state type and a second fault state type in advance, and the priorities of the three state types are sequentially increased. And selecting the state type with higher priority from the plurality of determined state types when the state types determined according to the state information of different dimensions of the automatic driving vehicle are different.
For example, the autonomous vehicle determines that the autonomous vehicle is in a normal state according to the state information that the door is closed, determines that the autonomous vehicle is in a first fault state according to the state information that the temperature of the vehicle is higher than a preset temperature, and determines that the state type of the autonomous vehicle is in the first fault state when the autonomous vehicle is determined to be in the normal state type and the first fault state type according to the two state information because the preset normal state type, the first fault state type, and the second fault state type are sequentially increased in priority, and the first fault state is higher in priority than the normal state.

FIG. 7 is a flow chart illustrating another prompting method, according to an exemplary embodiment, for application to an autonomous vehicle, as shown in FIG. 7, the method including:
701. the autonomous vehicle collects environmental information currently within range and performs either step 702 or 708.
Autonomous vehicles may include autonomous cars, autonomous trucks, autonomous motorcycles, and the like. Components in autonomous vehicles include engines, chassis, and body accessories including internet of vehicles wireless devices, sound receivers, mechanical or electronic horns, fuel tanks, tires, car covers, doors, car glass, mirrors, license plate carriers, seat and seat accessories, car bearings, armrests, handles, cab and cab accessories, airbags, safety belts, window lifters, antennas, wipers, mufflers, horns, weather-stripping bumpers, luggage, exhaust pipes, and the like.
The combination of a software system and a hardware system is required for realizing automatic driving of the automatic driving vehicle, and the software system comprises a sensing module, a positioning module and a decision module. The sensing module and the positioning module identify and classify other intelligent agents, the decision-making module judges whether the other intelligent agents are special vehicles or not, meet with automatic driving vehicles or not, and are abnormal or not according to the behaviors of the other intelligent agents, and then the other intelligent agents are interacted by an active interaction means. The hardware system includes components equipped with the autonomous vehicle for interacting with other agents, including warning lights, sirens, display screens, speakers, internet-of-vehicles wireless devices, and the like.
In the embodiment of the application, considering that the automatic driving vehicle may encounter a dangerous area in the driving process, when the dangerous area is located in a lane where the automatic driving vehicle is currently located and in front of the automatic driving vehicle, the driving of the automatic driving vehicle is obstructed, and the automatic driving vehicle needs to change a driving route or perform parking operation so as to avoid traffic accidents.
Therefore, in order to detect a dangerous area in time and realize safe automatic driving, the automatic driving vehicle needs to acquire environmental information in the current range during the driving process. For example, the autonomous vehicle may be configured with a collection device by which environmental information of the environment in which the autonomous vehicle is currently located is collected.
The range in which the autonomous vehicle is currently located refers to a range in which the autonomous vehicle can collect the environmental information, and may be determined according to a maximum distance at which the collection device of the autonomous vehicle collects the environmental information, and may be a circular region formed by taking the autonomous vehicle as a center of a circle and taking the maximum distance at which the environmental information is collected as a radius, or a sector region formed by taking the autonomous vehicle as a center of a circle, taking the maximum distance at which the environmental information is collected as a radius and taking a collection angle of the collection device as a vertex angle, or the like.
This collection equipment can include at least one item in camera, laser radar, millimeter wave radar, infrared sensor, humidity transducer or the temperature sensor, can gather the environmental information of different grade type through different collection equipment. For example, the environmental information may include temperature, humidity, road flatness, width of a passable area of the road, distance between an obstacle and the autonomous vehicle, contour information of nearby vehicles, and the like.
702. And when the automatic driving vehicle determines that the preset dangerous area exists in the first lane where the automatic driving vehicle is located at present according to the environmental information, the passing area is determined again, step 703 or 705 is executed, and step 707 is executed.
The preset dangerous area refers to an area which obstructs the traffic of vehicles, and can include an area where a fault vehicle is located, a road construction area or a road enclosed area and the like.
In one possible implementation manner, the preset dangerous area may be an area where the safe passing width is smaller than a preset lane width, and when the detected environmental information is that the front road passable width is smaller than the preset lane width, it is determined that the front is the preset dangerous area.
In another possible implementation manner, the autonomous vehicle may reconstruct a road structure according to road information included in the environment information, determine whether the reconstructed road structure is consistent with a road structure stored in the autonomous vehicle, determine an area in the road where the road structure changes if the reconstructed road structure is inconsistent with the road structure stored in the autonomous vehicle, perform scene recognition on the area, and determine a current scene of the area to determine whether the area is a preset dangerous area. For example, if the area is determined to be in a construction scene through scene recognition and temporarily not to pass through, the area is determined to be a preset dangerous area, or if the area is determined to be in a vehicle fault scene through scene recognition and not to pass through due to a traffic accident occurring in the area, the area is determined to be the preset dangerous area.
The automatic driving vehicle can determine a condition that the environmental information of the preset dangerous area should meet, when the automatic driving vehicle runs in the first lane and the environmental information is collected, whether the environmental information of the first lane meets the preset condition or not is judged, and when the environmental information meets the preset condition, the automatic driving vehicle is determined to have the preset dangerous area in the first lane where the automatic driving vehicle is located currently. And when the environmental information does not meet the preset condition, determining that no preset dangerous area exists in the first lane where the automatic driving vehicle is located currently.
Or the automatic driving vehicle determines the environmental characteristics corresponding to the environmental information of the preset dangerous area, when the automatic driving vehicle runs in the first lane and the environmental information of the first lane is collected, the environmental characteristics corresponding to the environmental information are obtained and matched with the environmental characteristics corresponding to the preset dangerous area, and when the similarity between the environmental characteristics and the environmental characteristics is higher than a preset threshold value, the automatic driving vehicle is determined to have the preset dangerous area in the first lane where the automatic driving vehicle is located currently. And when the similarity of the first lane and the second lane is not higher than a preset threshold value, determining that no preset dangerous area exists in the first lane where the automatic driving vehicle is located currently.
When the automatic driving vehicle determines that the preset dangerous area exists in the first lane, the passing area needs to be determined again in order to ensure safety.
For example, the autonomous vehicle may determine an area having a passable width larger than a preset lane width as the newly determined passage area, based on the collected environmental information.
In one possible implementation manner, the automatic driving vehicle determines that a preset dangerous area exists in a first lane where the automatic driving vehicle is located currently according to the environment information, determines the first lane where the automatic driving vehicle is located currently, detects a lane boundary, and determines a second lane adjacent to the first lane.
Since the first lane is adjacent to the second lane and a portion of the second lane is also located within a range in which the autonomous vehicle is currently located, the environmental information collected by the autonomous vehicle includes environmental information of the first lane and environmental information of the second lane, and a lane boundary may be detected and the second lane may be determined according to the collected environmental information.
Further, after the autonomous vehicle determines the second lane, it may be determined whether the second lane has a preset danger zone. The manner of determining whether the second lane has the preset danger zone is similar to the manner of determining whether the first lane has the preset danger zone, and is not described herein again. And when the second lane does not have the preset dangerous area, determining that the second lane is the passing area of the automatic driving vehicle. When the preset danger area also exists in the second lane, the second lane is not determined as the passing area.
In another possible implementation manner, the autonomous vehicle determines that a preset dangerous area exists in the first road where the autonomous vehicle is located currently according to the environment information, and at this time, the autonomous vehicle may determine whether a passable area exists in other spaces outside the current road according to the environment information. For example, a boundary line between a road and a free space road surface other than the road is detected, a passable area width of the free space road surface is determined, and when the passable area width is larger than a width of the autonomous vehicle, the passable area of the free space road surface is determined as a passage area of the autonomous vehicle.
Through the two modes, two types of passing areas can be provided, wherein one is a second lane adjacent to the first lane in the current road, and the other is a free space road surface outside the road. It should be noted that the priority of the lane is higher than that of the free space road surface, that is, when it is detected that both the lane can be used as a passable area and the free space road surface which is not located in any lane can be used as a passable area, the lane is preferentially selected as the passable area.
Depending on the type of traffic zone determined, the following steps 703 or 705 may be performed.
703. When the passage area is a second lane different from the first lane, the autonomous vehicle travels from the first lane to the second lane.
And when the automatic driving vehicle detects that a preset dangerous area exists in front of the lane where the automatic driving vehicle is located and the newly determined passing area is a second lane different from the first lane, executing lane changing operation and driving from the first lane to the second lane.
704. During the course of traveling from the first lane to the second lane, the autonomous vehicle outputs a prompt corresponding to a lane change operation through the output device.

The loudspeaker can be one or more, and can be installed on the roof or the side. The siren may include a mechanical or electronic siren, etc. The prompting lamp comprises a steering lamp, a fog lamp, a clearance lamp and the like.
The automatic driving vehicle can establish a corresponding relation between the lane changing operation and the prompt information, when the automatic driving vehicle executes the lane changing operation, the corresponding relation is inquired to obtain the prompt information corresponding to the lane changing operation, and the prompt information corresponding to the lane changing operation is output through the output equipment of the automatic driving vehicle.
In one possible implementation, the outputting, by the output device, the prompt information corresponding to the lane change operation may include at least one of:

Wherein, the warning light comprises a turn light, a fog light, a clearance light and the like.
After the lane change to the second lane, the autonomous vehicle may run in the second lane, and at this time, the autonomous vehicle does not need to input the prompt information corresponding to the lane change operation, but may also output the prompt information corresponding to the current state information of the autonomous vehicle or the currently executed driving operation.
705. When the passing area is not located in any lane, the autonomous vehicle travels from the first lane to the passing area.
706. During the process of driving from the first lane to the passing area and during the process of driving in the passing area, the automatic driving vehicle outputs prompt information for keeping the vehicle distance through the output device.
When the automatic driving vehicle detects that a preset dangerous area exists in front of the lane where the automatic driving vehicle is located, the newly determined passing area is located on the free space road surface and is not located in any lane, the automatic driving vehicle travels to the passing area from the first lane and then travels in the passing area.
In the process of driving the automatic driving vehicle from the first lane to the passing area and driving in the passing area, lane constraint is lacked, the probability of unknown risk is high, and safety is poor, so that in the process of driving from the first lane to the passing area and in the process of driving in the passing area, prompt information for keeping the distance between vehicles needs to be output through an output device.

Therefore, when the common vehicle meets the vehicle, the common vehicle needs to avoid and cannot hinder the normal running of the vehicle.
In the embodiment of the present application, in order to solve the above problem, an autonomous vehicle may set a condition that a target vehicle belonging to a preset avoidance type should meet, so as to identify the target vehicle belonging to the preset avoidance type during a driving process, when the target vehicle is located in a current lane of the autonomous vehicle or in a lane adjacent to the current lane of the autonomous vehicle, and the autonomous vehicle may block normal driving of the target vehicle, the autonomous vehicle needs to perform operations of accelerating, decelerating and avoiding, or changing lanes to drive, so as to avoid affecting normal driving of the target vehicle.

When the automatic driving vehicle obtains the vehicle characteristics in the current range in the driving process, the vehicle characteristics are matched with the preset vehicle characteristics corresponding to the preset avoidance type so as to determine whether the vehicle belongs to the target vehicle of the preset avoidance type.
For example, for a police vehicle, the autonomous vehicle may determine preset vehicle characteristics of the police vehicle including: the vehicle body is drawn with symbolic characters, the vehicle lamp with color is arranged above the vehicle roof, and the vehicle lamp flickers and gives out siren sounds and the like in the driving process.
1103. And when the similarity of the vehicle characteristics and the preset vehicle characteristics is greater than a preset threshold value, the automatic driving vehicle determines that the vehicle is a target vehicle belonging to a preset avoidance type.

Thus, the above step 1104 may include the following implementations (1) - (3):
(1) if the autonomous vehicle is traveling in the same direction as the target vehicle and the autonomous vehicle is located behind the target vehicle, it remains traveling behind the target vehicle.
For example, if the autonomous vehicle recognizes the rear of the target vehicle by the camera arranged in front, it can be determined that the autonomous vehicle travels in the same direction as the target vehicle, and the autonomous vehicle is located behind the target vehicle, and at this time, the autonomous vehicle may travel behind the target vehicle.
(2) And if the automatic driving vehicle runs in the same direction as the target vehicle and the automatic driving vehicle is positioned in front of the target vehicle, avoiding the target vehicle.
For example, if the autonomous vehicle recognizes the head of the target vehicle by the camera disposed at the rear, it can be determined that the autonomous vehicle travels in the same direction as the target vehicle, and the autonomous vehicle is located in front of the target vehicle, and needs to avoid the target vehicle.
Further, the automatic driving vehicle can also consider the current lane and the current lane of the target vehicle, and determine whether to avoid the target vehicle according to the lane.

At this time, the autonomous vehicle may affect the traveling of the target vehicle, and in order to ensure the normal traveling of the target vehicle, the autonomous vehicle may perform an acceleration operation to ensure that the traveling speed of the target vehicle is not affected by the traveling speed of the target vehicle. In addition, the autonomous vehicle may also perform lane change operations, changing into other lanes, so that the target vehicle can pass.
In one possible implementation, if the autonomous vehicle travels in the same direction as the target vehicle, the autonomous vehicle is located in front of the target vehicle, the autonomous vehicle and the target vehicle are located in the same lane, and a traffic zone exists in an adjacent lane, a lane change operation is performed;
in another possible implementation, if the autonomous vehicle travels in the same direction as the target vehicle, the autonomous vehicle is located in front of the target vehicle, the autonomous vehicle is located in the same lane as the target vehicle, but there is no traffic area in an adjacent lane, an acceleration operation is performed until a lane change operation is performed when there is a traffic area in an adjacent lane.

As shown in fig. 12, whether a target vehicle belonging to a preset avoidance type exists in a current range of the autonomous vehicle is judged, if yes, the position of the target vehicle is displayed through a display screen, the position of the target vehicle is played through a loudspeaker, then according to the processing flow shown in fig. 12, the driving direction and the relative position of the autonomous vehicle and the target vehicle are sequentially determined, whether the autonomous vehicle is located in the same lane, whether the autonomous vehicle meets the vehicle, and the situation of the lane adjacent to the autonomous vehicle determines which driving operation the autonomous vehicle executes, and the driving operation executed by the autonomous vehicle is prompted through the display screen, the loudspeaker and the prompting lamp configured for the autonomous vehicle.
It should be noted that, when the autonomous driving vehicle is the target vehicle, the autonomous driving vehicle normally runs without avoiding other target vehicles belonging to the preset avoidance type within the current range, so that the prompt method provided by the embodiment of the present application is not required to be executed. Or, the autonomous vehicle itself is a target vehicle, but no task is currently executed, and another target vehicle belonging to a preset avoidance type in the current range still needs to be avoided, so the method provided by the embodiment of the present application can be adopted.

The fourth interaction mode is as follows: and prompting the meeting state of the automatic driving vehicle and the target vehicle.
FIG. 13 is a flow chart illustrating a method of prompting, as shown in FIG. 13, for use with an autonomous vehicle, the method including:
1301. the autonomous vehicle identifies a target vehicle, which is a vehicle whose travel route intersects with the travel route of the autonomous vehicle.
There are many vehicles on the road, and the vehicles are classified into a vehicle traveling in the same direction as the autonomous vehicle and a vehicle traveling in opposite directions to the autonomous vehicle according to the traveling direction, a vehicle in the same lane as the autonomous vehicle, a vehicle in an adjacent lane to the autonomous vehicle, and a vehicle in a non-adjacent lane to the autonomous vehicle according to the traveling lane. The vehicle in the lane not adjacent to the autonomous vehicle does not intersect with the autonomous vehicle and thus does not affect the traveling of the autonomous vehicle, and both the vehicle in the same lane as the autonomous vehicle and the vehicle in the lane adjacent to the autonomous vehicle may intersect with the autonomous vehicle.
Therefore, in order to realize safe vehicle meeting, the autonomous vehicle needs to identify a target vehicle, i.e., a vehicle whose travel route intersects with the travel route of the autonomous vehicle, while traveling. The method specifically comprises the following conditions:
(1-1) identifying a vehicle in a second lane as a target vehicle when an operation to change from a first lane to the second lane is performed.
When the automatic driving vehicle runs in a first lane where the automatic driving vehicle is located currently, the automatic driving vehicle possibly meets the situation that the front of the first lane where the automatic driving vehicle is located currently is closed, repaired or abnormally disconnected, the automatic driving vehicle needs to be converged into an adjacent lane, namely, the automatic driving vehicle is changed from the first lane where the automatic driving vehicle is located currently to an adjacent second lane so as to achieve normal running, before the lane is changed, the automatic driving vehicle needs to identify whether other vehicles exist in the second lane, and the vehicles in the second lane are used as target vehicles.
(1-2) identifying a vehicle traveling from the other lane to the first lane where the vehicle is currently located, as a target vehicle. Or, identifying a vehicle, of lanes adjacent to the first lane, in which the current vehicle is located, with the driving direction pointing to the first lane as the target vehicle.
When the autonomous vehicle runs in the first lane where the autonomous vehicle is currently located, the autonomous vehicle may encounter a situation that other vehicles in adjacent lanes merge into the first lane and prepare to run in front of the autonomous vehicle, and when the other vehicles merge into the first lane, the autonomous vehicle may be influenced to normally run, or a situation that the running direction of the other vehicles in the adjacent lanes points to the first lane may be encountered, which indicates that the autonomous vehicle is running towards the first lane and may merge into the first lane.
In order to achieve safe driving, the autonomous vehicle needs to recognize whether another vehicle in an adjacent lane is ready to merge into or is merging into, and this vehicle is taken as a target vehicle.
And (1-3) identifying a vehicle which is positioned in front of the automatic driving vehicle and has a running speed lower than that of the automatic driving vehicle in the current first lane as a target vehicle.
When the autonomous vehicle runs in the first lane, the autonomous vehicle may run at a speed lower than the running speed of the autonomous vehicle in the same lane, and the autonomous vehicle will perform an operation to override the preceding vehicle. To ensure safe travel during an override, the autonomous vehicle needs to identify a vehicle that is located ahead of the autonomous vehicle and that has a travel speed less than the travel speed of the autonomous vehicle as the target vehicle.
And (1-4) identifying a vehicle which is positioned behind the automatic driving vehicle and has a driving speed greater than the driving speed of the automatic driving vehicle in the first lane where the automatic driving vehicle is positioned at present as the target vehicle.
When the automatic driving vehicle runs in the first lane where the automatic driving vehicle is currently located, the situation that the running speed of the rear vehicle in the same lane is greater than the running speed of the automatic driving vehicle may be encountered, at this time, the rear vehicle may perform driving operation over the automatic driving vehicle, for safe running, the automatic driving vehicle needs to actively perform avoidance so as to avoid conflict with the driving operation of the rear vehicle, and for timely avoidance, the automatic driving vehicle needs to identify a vehicle which is located behind the automatic driving vehicle in the first lane where the automatic driving vehicle is currently located and has a running speed greater than the running speed of the automatic driving vehicle, and use the vehicle as a target vehicle.
1302. The autonomous vehicle performs a driving operation according to the position of the autonomous vehicle and the position of the target vehicle.
After determining that the driving route of the automatic driving vehicle intersects with the target vehicle, the automatic driving vehicle needs to determine which driving operation to execute according to the position of the automatic driving vehicle and the position of the target vehicle so as to realize safe automatic driving.
Optionally, the autonomous vehicle may further determine what driving operation to perform according to the position of the autonomous vehicle and the position of the target vehicle, the speed of the autonomous vehicle and the speed of the target vehicle, and the actual conditions of the road, so as to achieve safe autonomous driving.
Alternatively, in the case of the step (1-1) above, the step 1302 may include the steps of:
(2-1) performing a waiting operation at a boundary area of the first lane and the second lane;
when the automatic driving vehicle is converged into an adjacent lane, namely when the current first lane is changed into an adjacent second lane, the converging time needs to be determined according to the position of the automatic driving vehicle and the position of a target vehicle, and when meeting conditions are not met, the automatic driving vehicle executes waiting operation in a junction area of the first lane and the second lane.
In addition, the determination of the integration timing may take into account not only the position of the autonomous vehicle and the position of the target vehicle, but also the speed of the autonomous vehicle and the speed of the target vehicle.
In one possible implementation, when there is another vehicle having a higher speed and a shorter distance from the autonomous vehicle in a second lane adjacent to the first lane in which the autonomous vehicle is located, the autonomous vehicle needs to perform a waiting operation in an intersection area of the first lane and the second lane.
(2-2) performing an operation of traveling from the first lane to the second lane when the position of the autonomous vehicle and the position of the target vehicle satisfy a vehicle-meeting condition.
When the automatic driving vehicle determines that the meeting condition is met, namely when no target vehicle which is close to the automatic driving vehicle and has a high speed exists in the second lane, the automatic driving vehicle carries out operation of driving from the first lane to the second lane.
In the case of step (1-2) above, step 1302 may include the steps of:
(2-3) performing a deceleration operation, a lane change operation, or a current keeping operation according to the position of the autonomous vehicle and the position of the target vehicle.
The target vehicle of the adjacent lane of the automatic driving vehicle is converged into the first lane and is ready to run ahead of the automatic driving vehicle, and the automatic driving vehicle needs to determine the driving operation which the automatic driving vehicle needs to perform according to the position of the automatic driving vehicle and the position of the target vehicle.
In one possible implementation manner, when the automatic driving vehicle determines that the automatic driving vehicle needs to keep running in the current lane according to the position of the automatic driving vehicle and the position of the target vehicle, but needs to decelerate and avoid the target vehicle to be merged, the automatic driving vehicle executes deceleration operation to avoid.
For example, the autonomous vehicle determines that a target vehicle to which an adjacent lane is to be merged is close to the autonomous vehicle and is fast, and performs a deceleration operation to avoid the target vehicle for safety.
In one possible implementation manner, the autonomous vehicle executes lane change operation for avoidance when determining that the autonomous vehicle needs to change lanes to drive for avoidance of the target vehicle to be imported according to the position of the autonomous vehicle and the position of the target vehicle, the speed of the autonomous vehicle and the speed of the target vehicle and whether the adjacent other lane meets the lane change condition.
For example, the autonomous vehicle determines that a target vehicle to which an adjacent lane is to be merged is close to the autonomous vehicle and is fast, and the other lane adjacent to the autonomous vehicle satisfies a lane change condition. Lane changing for avoidance can also avoid the influence of sudden deceleration operation on normal running of the rear vehicle in the first lane, avoid rear-end collision caused by the rear vehicle not responding to the sudden deceleration of the automatic driving vehicle, and improve safety.
In one possible implementation, when the autonomous vehicle determines that the autonomous vehicle does not need to avoid according to the position of the autonomous vehicle and the position of the target vehicle and the speed of the autonomous vehicle and the speed of the target vehicle, the autonomous vehicle maintains the current driving operation and does not avoid the target vehicle.
For example, when the autonomous vehicle determines that the target vehicle to which the adjacent lane is to be merged is far from the autonomous vehicle and the autonomous vehicle does not affect the merging of the target vehicle, the autonomous vehicle maintains the current running operation without avoiding the target vehicle.
In the case of the above step (1-3), step 1302 may include the steps of:
(2-4) performing an operation to override the target vehicle.
When a target vehicle with a running speed lower than that of the automatic driving vehicle exists in front of the automatic driving vehicle in a first lane where the automatic driving vehicle is currently located, the automatic driving vehicle performs a driving operation exceeding the target vehicle.
Wherein performing an operation that overrides the target vehicle comprises: the autonomous vehicle travels from the first lane into the adjacent lane, and performs an acceleration operation, overtakes the target vehicle, and travels from the adjacent lane into the first lane when the autonomous vehicle is located in front of the target vehicle, thereby traveling in front of the target vehicle.
(2-5) continuing to perform the driving operation in the first lane after completion of the operation to perform the override of the target vehicle.
In the case of the above steps (1-4), step 1302 may include the steps of:
and (2-6) performing an operation of avoiding the target vehicle.
When a target vehicle with a running speed higher than that of the automatic driving vehicle exists behind the automatic driving vehicle in a first lane where the automatic driving vehicle is located, if the rear vehicle executes a driving operation of overtaking, the automatic driving vehicle executes an operation of avoiding the target vehicle.
(2-7) continuing to perform the driving operation in the first lane after the target vehicle overrides the autonomous vehicle.
When the target vehicle performs the operation of overriding the automatic driving vehicle, the target vehicle can travel from the first lane to the adjacent lane and perform the acceleration operation, and at the moment, the automatic driving vehicle can perform the deceleration operation or can also normally travel without performing the deceleration operation. And then, when the target vehicle is positioned in front of the automatic driving vehicle, the automatic driving vehicle drives from the adjacent lane to the first lane, and at the moment, the automatic driving vehicle can execute deceleration operation to avoid the target vehicle until the target vehicle is converged into the first lane, and the automatic driving vehicle can recover the original driving speed and safely drive behind the target vehicle.

FIG. 15 is a flow chart illustrating a method of prompting, as shown in FIG. 15, for use with an autonomous vehicle, the method including:
1501. the autonomous vehicle identifies a vehicle in the road currently located in the direction opposite to the traveling direction of the autonomous vehicle as a target vehicle.
Since many vehicles exist on the road, and vehicles on the same road as the autonomous vehicles and in the opposite direction to the autonomous vehicles meet the autonomous vehicles, and affect the traveling of the autonomous vehicles, in order to safely meet the autonomous vehicles and realize safe autonomous driving, the autonomous vehicles need to identify target vehicles, that is, vehicles in the opposite direction to the autonomous vehicles in the current road.
1502. And the automatic driving vehicle determines the meeting position of the automatic driving vehicle and the target vehicle according to the position of the automatic driving vehicle and the position of the target vehicle.
When there is no obstacle in front of the autonomous vehicle in the lane in which the autonomous vehicle is located, the autonomous vehicle may determine a meeting location according to the location of the autonomous vehicle and the location of the target vehicle, and the speed of the autonomous vehicle and the speed of the target vehicle.
When an obstacle exists in front of the automatically-driven vehicle in a lane where the automatically-driven vehicle is located, the automatically-driven vehicle needs to determine the position of the obstacle in front of the automatically-driven vehicle, and determine a vehicle-meeting position according to the position of the obstacle and the positions of the automatically-driven vehicle and a target vehicle, wherein the vehicle-meeting position can be located behind the obstacle, namely the automatically-driven vehicle and the target vehicle complete vehicle meeting first and then travel through the obstacle. The meeting position can also be positioned in front of the barrier, namely the automatic driving vehicle firstly runs through the barrier and then meets other vehicles. The following two cases are specifically distinguished:
and (1-1) the meeting position is behind the barrier.
In one possible implementation, the autonomous vehicle determines that the other vehicles running in opposite directions are closer to the obstacle and faster, and then the autonomous vehicle determines that the meeting position is behind the obstacle.
And (1-2) the meeting position is positioned in front of the barrier.
In one possible implementation, the autonomous vehicle determines that the other vehicles running in opposite directions are far away from the obstacle and the speed is slow, and the autonomous vehicle determines that the meeting position is in front of the obstacle when the autonomous vehicle is close to the obstacle.
When the road where the automatically-driven vehicle is located is blocked, for example, the road section is a curve or a winding road, and the automatically-driven vehicle cannot determine whether a target vehicle running in opposite directions exists in the front or not and whether an obstacle exists in the front or not, the automatically-driven vehicle needs to perform a speed reduction operation to realize safe running, and prompt information corresponding to the speed reduction operation is output through an output device, for example, a whistle operation can be performed according to a whistle rhythm corresponding to the speed reduction operation.
The automatic driving vehicle needs to comprehensively utilize multiple means to identify vehicles in the shading area of the automatic driving vehicle in the road, wherein the vehicles are opposite to the driving direction of the automatic driving vehicle, and the specific process comprises at least one of the following steps:
(1) and monitoring the whistle sound emitted by the vehicle, and taking the vehicle emitting the whistle sound as a target vehicle.
When there is the sheltering zone in the road place ahead that the autonomous driving vehicle goes, the autonomous driving vehicle can monitor the whistle sound that other vehicles sent, and the whistle sound that sends when receiving other vehicles can confirm that the place ahead has other vehicles.
The automatic driving vehicle can set flute sound characteristics corresponding to the flute sound emitted by the vehicle, monitor the sound in the current environment, judge whether the similarity between the sound characteristics and the flute sound characteristics is higher than a preset threshold value, and determine that other vehicles exist in the current environment if the similarity between the sound characteristics and the flute sound characteristics is higher than the preset threshold value. Or if the similarity between the sound feature and the whistle feature is higher than a preset threshold value and the source direction of the sound is the front of the automatic driving vehicle, determining that other vehicles exist in front.
(2) And identifying the light emitted by the vehicle, and taking the vehicle emitting the light as a target vehicle.
When a shielded area exists in front of a driving road of the automatic driving vehicle, the automatic driving vehicle can recognize light emitted by other vehicles, and when the light emitted by other vehicles is received, the existence of other vehicles in front can be determined.
The automatic driving vehicle can set light characteristics corresponding to light emitted by the vehicle, the automatic driving vehicle can shoot a picture of a front environment, the light characteristics in the picture are extracted, whether the similarity between the light characteristics and the set light characteristics is higher than a preset threshold value or not is judged, and if the similarity is higher than the preset threshold value, other vehicles in the front are determined.
(3) And sending a vehicle identification request to the wireless equipment in the Internet of vehicles, receiving vehicle information returned by the wireless equipment in the Internet of vehicles, and taking the vehicle corresponding to the vehicle information as a target vehicle.
When a shielded area exists in front of a running road of the automatic driving vehicle, the automatic driving vehicle can send a vehicle identification request to the internet of vehicles wireless device, the internet of vehicles wireless device receives the request of the automatic driving vehicle, screens vehicle information in a preset range of the position of the automatic driving vehicle and returns the vehicle information to the automatic driving vehicle, and the automatic driving vehicle receives the vehicle information returned by the internet of vehicles wireless device, so that whether other vehicles exist in front or not can be determined.
The preset range is a circular area formed by taking the automatic driving vehicle as a circle center and taking the preset distance as a radius, or a sector area formed by taking the automatic driving vehicle as a circle center, taking the preset distance as a radius and taking the preset angle as a vertex angle, and the like.
The wireless device of the internet of vehicles can be a street lamp arranged on the roadside, a charging pile or other public facilities, or can also be a management server for logging in an automatic driving vehicle and the like. The wireless device of the internet of vehicles can collect the vehicle information sent by a plurality of devices and send the vehicle information to other devices, so that the vehicle information is shared.
The vehicle information may include a position of the vehicle, and when the autonomous vehicle receives the vehicle information, the vehicle existing within the preset range and a specific position of the vehicle may be determined.
In addition, the autonomous vehicle may also detect an obstacle in front of the autonomous vehicle and within a shielded area of the autonomous vehicle. The shaded area is an area in front of the field of view of the autonomous vehicle. Alternatively, a convex mirror may be provided in the road, which has a reflective effect in which obstacles in the shaded area of the autonomous vehicle may reflect. When the convex mirror is located within the field of view of the autonomous vehicle, the autonomous vehicle may photograph the convex mirror to obtain a picture of the convex mirror, and identify the position of an obstacle included in the picture of the convex mirror.
The automatic driving vehicle can acquire the relative position of the automatic driving vehicle and the convex mirror, and can also acquire the position and the angle of an obstacle in a picture of the convex mirror, so that the relative position of the obstacle and the automatic driving vehicle is determined.
The convex mirror is arranged at the position with poor vision, such as a mountain road or a curve, the driver can see the scene in the blind area through the convex mirror, the blind area can be reduced, the automatic driving vehicle can identify the picture in the convex mirror, and whether the front part has the obstacle or not and the position of the obstacle can be identified according to the picture in the convex mirror.
The autonomous vehicle may then plan a meeting location according to the location of the autonomous vehicle, the location of the target vehicle, and the location of the obstacle. After the position of the target vehicle and the position of the obstacle are both clear, the way of planning the meeting position is similar to the above way, and is not described herein again.
1503. The automatic driving vehicle executes driving operation according to the meeting position.
In the case that no obstacle exists in step 1502, after the autonomous vehicle determines the meeting place, when the autonomous vehicle reaches the meeting place within the preset distance, the autonomous vehicle performs a deceleration operation, and may also travel toward the edge of the road to leave a space for meeting with the target vehicle.
In the case of (1-1) in the above step 1502, step 1503 may include (2-1) and (2-2):
and (2-1) when the meeting position is behind the obstacle, if the autonomous vehicle is far away from the obstacle, the autonomous vehicle performs a deceleration operation.
And (2-2) when the meeting position is behind the obstacle, if the autonomous vehicle is closer to the obstacle, the autonomous vehicle performs a parking operation.
In the case of (1-2) in the above step 1502, step 1503 may include (2-3):
and (2-3) when the meeting position is positioned in front of the obstacle, the automatic driving vehicle performs acceleration operation, quickly passes by the obstacle and meets the target vehicle.
When the autonomous vehicle meets a target vehicle when there is no obstacle in front of the autonomous vehicle, the autonomous vehicle needs to run at a reduced speed to avoid the target vehicle for safety.
In a possible implementation manner, in a vehicle meeting process, the automatic driving vehicle acquires a distance between the automatic driving vehicle and the target vehicle, when the distance between the automatic driving vehicle and the target vehicle is not less than a preset distance, the automatic driving vehicle normally runs, as the distance between the automatic driving vehicle and the target vehicle is closer and closer, when the distance between the automatic driving vehicle and the target vehicle is less than the preset distance, the deceleration operation is executed so that the automatic driving vehicle and the target vehicle can safely meet, and then as the distance between the automatic driving vehicle and the target vehicle is farther and farther, when the distance between the automatic driving vehicle and the target vehicle is not less than the preset distance, the deceleration operation is stopped, and at this time, the normal running speed can be recovered.
In a possible implementation manner, when the automatically driven vehicle meets the target vehicle, if the target vehicle is not decelerated in advance and the meeting risk is high under the condition of high-speed opposite driving, the automatically driven vehicle is forced to stop and avoid, a parking driving operation needs to be executed to realize safe meeting, and prompt information corresponding to the parking driving operation is output through an output device, wherein the prompt manner is similar to the above (2-2), and is not repeated herein.

FIG. 17 is a flow diagram illustrating a hinting method according to an exemplary embodiment, as shown in FIG. 17, including:
1701. the autonomous vehicle collects behavior data of agents currently within range.
Vehicles running on the road, pedestrians and animals coming and going can be called intelligent bodies. When the vehicle runs, the vehicle cannot run along the road center line or even run left or right suddenly due to fatigue driving, distraction or mobile phone playing of a driver, or the non-motor vehicle and the automatic driving vehicle rush to run. When the pedestrian walks, it is probably forbidden that the rear vehicle suddenly goes out of the vehicle or the pedestrian optimistically seizes the road with the automatic driving vehicle. Animals may be caught in the road and influence the autonomous vehicle. All the behaviors belong to abnormal behaviors, and an agent with the abnormal behavior is an abnormal agent.
When the abnormal intelligent agent is in the current range of the automatic driving vehicle, the safe driving of the automatic driving vehicle can be influenced, and the automatic driving needs to change lanes for driving, decelerate for driving or execute parking operation so as to avoid traffic accidents.
Therefore, in order to timely identify the abnormal intelligent agents in the current range and realize safe automatic driving, the behavior data of the intelligent agents in the current range needs to be collected during the driving process of the automatic driving vehicle, so as to identify the abnormal intelligent agents in the range according to the collected behavior data.
Optionally, the autonomous vehicle may be configured with a collection device, and the collection device collects behavior data of agents currently located within the range.
The range in which the autonomous vehicle is currently located refers to a range in which the autonomous vehicle can recognize environmental information, and may be determined according to a maximum distance at which the acquisition device of the autonomous vehicle acquires the environmental information, and may be a circular region formed by taking the autonomous vehicle as a center of a circle and taking the maximum distance at which the environmental information is acquired as a radius, or a sector region formed by taking the autonomous vehicle as a center of a circle, taking the maximum distance at which the environmental information is acquired as a radius and taking an acquisition angle of the acquisition device as a vertex angle, or the like.
The acquisition equipment can comprise at least one of a camera, a laser radar, a millimeter wave radar, an infrared sensor, a humidity sensor or a temperature sensor, and different types of behavior data can be acquired through different acquisition equipment. For example, the behavior data may include a travel route of the vehicle, a travel speed of the vehicle, a walking direction of a pedestrian, a position of an animal, and the like.
1702. The autonomous vehicle matches the behavior data with preset abnormal behavior data.
The autonomous driving vehicle can set preset abnormal behavior data according to the behavior characteristics of the abnormal intelligent agent. When the automatic driving vehicle runs, acquiring the behavior data of the intelligent agent in the current range, and matching the behavior data with the preset abnormal behavior data to determine whether the intelligent agent is an abnormal intelligent agent.
Optionally, in consideration of the fact that the intelligent agent includes multiple categories, the autonomous vehicle may set preset abnormal behavior data corresponding to the intelligent agent of each category, and then the autonomous vehicle recognizes the intelligent agent, and when acquiring the behavior data of the intelligent agent, determines the category to which the intelligent agent belongs according to the behavior data, acquires the preset abnormal behavior data corresponding to the category, and matches the behavior data with the preset abnormal behavior data.
For example, for an abnormal vehicle, the autonomous vehicle may determine that the preset abnormal behavior data of the abnormal vehicle includes: the driving route sways left and right, does not drive on a specified lane according to road regulations, does not drive along the road center line, and the like. For an abnormal pedestrian, the autonomous vehicle may determine that the preset abnormal behavior data of the abnormal pedestrian includes: crossing traffic, standing in the road, sudden fleeing, etc. For abnormal animals, the autonomous vehicle may determine that the preset behavior data of the abnormal animal includes: stay on the road or stop at the side of the road.
1703. And when the similarity of the behavior data and the preset abnormal behavior data is greater than a preset threshold value, the automatic driving vehicle determines that the intelligent agent is an abnormal intelligent agent.
The method comprises the steps that the similarity between behavior data and preset abnormal behavior data is calculated by the automatic driving vehicle, whether the similarity is larger than a preset threshold value or not is judged, if the similarity is larger than the preset threshold value, the behavior data are similar to the preset abnormal behavior data, the currently recognized intelligent agent can be determined to be an abnormal intelligent agent, and if the similarity is not larger than the preset threshold value, the behavior data are not similar to the preset abnormal behavior data, the currently recognized intelligent agent can be determined not to be the abnormal intelligent agent.
When the similarity between the behavior data and the preset abnormal behavior data is calculated, a first feature vector corresponding to the behavior data and a second feature vector corresponding to the preset abnormal behavior data can be obtained, and the similarity between the first feature vector and the second feature vector is calculated and used as the similarity between the behavior data and the preset abnormal behavior data. The similarity may be calculated in a cosine distance manner or in an euclidean distance manner, which is not limited in the embodiment of the present application.
Wherein the preset threshold may be set by the autonomous vehicle by default, or may be set according to the need for recognition accuracy.
Optionally, the preset abnormal behavior data may also include multiple types for the same category of agents, the autonomous vehicle may set multiple types of preset abnormal behavior data for each agent, and when the behavior data of an agent is identified, the preset abnormal behavior data whose similarity with the behavior data is greater than the preset threshold may be determined from the multiple types of preset abnormal behavior data in the above manner of calculating the similarity, at this time, not only may the agent be determined as an abnormal agent, but also which type of abnormal behavior the abnormal agent has occurred.
The first point to be noted is that the autonomous vehicle may include one or more agents currently within range, and similar operations may be performed for each agent to identify whether each agent is an abnormal agent.
The second point to be noted is that the step 1702-1703 is an optional step, and the automated driving vehicle may also identify the abnormal agent in other manners.

When the driving route of the vehicle is determined to be abnormal according to the behavior data, the vehicle can be determined to be an abnormal vehicle.

That is, the autonomous vehicle may collect behavior data of the vehicle currently located within the range, where the behavior data may include a position and a driving direction of the vehicle, and the driving route of the vehicle may be predicted according to the position and the driving direction of the vehicle. In addition, the pedestrian behavior data can be collected, the pedestrian behavior data comprise the position and the walking direction of the pedestrian, and the walking route of the pedestrian can be predicted according to the position and the walking direction of the pedestrian.
