It should be understood that the specific embodiments described herein are merely illustrative of the disclosed embodiments and are not intended to limit the disclosed embodiments.
First, before the technical solution of the embodiments of the present disclosure is specifically described, a description is given of a technical background or a technical evolution context on which the embodiments of the present disclosure are based. In general, in the field of intelligent driving, the current technical background is: with the popularization of intelligent driving vehicles, when using the intelligent driving vehicle, it is necessary to input a destination, the intelligent driving vehicle generates a travel route based on a current position and the destination, and travels according to the generated travel route. Therefore, the intelligent driving vehicle needs to be able to handle not only the running situation in the normal ideal state but also the running situation in some abnormal situations, such as an obstacle on a running road, a traffic accident, and the like. Therefore, the intelligent driving automobile needs to utilize the sensing equipment such as a camera, a radar and the like to predict the information of the driving corridor of the intelligent driving automobile, so as to carry out path planning on the intelligent driving automobile, thereby avoiding danger caused by abnormal conditions. Based on the background, the applicant discovers that the traditional technology has the problem of low accuracy of a planned lane corridor for running a vehicle through long-term model simulation research and development and collection, demonstration and verification of experimental data. Therefore, how to improve the accuracy of the lane corridor where the planned vehicle runs becomes a current challenge to be solved. In addition, it should be noted that, from the conventional technology, there is a low accuracy of the planned lane corridor in which the vehicle runs and the technical solutions described in the following embodiments, the applicant has made a lot of creative work.
The following describes a technical scheme related to an embodiment of the present disclosure in conjunction with a scenario in which the embodiment of the present disclosure is applied.
Fig. 1 is an application environment diagram of a path planning method according to an embodiment of the present application, and the path planning method provided by the embodiment of the present disclosure may be applied to the application environment shown in fig. 1. The first vehicle 102 is a currently used intelligent driving vehicle, the second vehicle 104 is a vehicle related to the driving intention of the first vehicle 102, and the first vehicle 102 communicates with the second vehicle 104, it may be understood that the second vehicle 104 may be a vehicle driven intelligently or a vehicle driven manually. The first and second vehicles may be, but are not limited to, various cars, commercial vehicles, buses, trucks, motorcycles, and the like.
Fig. 2 is a flow chart of a path planning method according to an embodiment of the present application, in an embodiment, as shown in fig. 2, a path planning method is provided, and the method is applied to the first vehicle in fig. 1 for illustration, and includes the following steps:
s201, traveling characteristic information of a first vehicle, traveling characteristic information of a second vehicle, which is a vehicle related to a traveling intention of the first vehicle, and traveling environment characteristic information of the first vehicle are acquired.
In this embodiment, the first vehicle is an intelligent driving car currently in use, i.e., a host vehicle; the second vehicle is a vehicle that is related to the traveling intention of the first vehicle, i.e., the other vehicle. A vehicle that is related to the traveling intention of the first vehicle may be understood as a vehicle that the first vehicle needs to pay attention to during traveling. For example, when the first vehicle travels in lane 1 and vehicle a is traveling in the vicinity of lane 2 on the left side of the first vehicle, the first vehicle needs to consider vehicle a if it wants to change lanes, and thus vehicle a is a second vehicle related to the traveling intention of the first vehicle.
Further, the first vehicle acquires the travel characteristic information of the first vehicle, the travel characteristic information of the second vehicle, and the travel environment characteristic information of the first vehicle related to the travel intention of the first vehicle. Wherein the driving characteristic information is a kinematically related parameter of the vehicle during driving, for example, the driving characteristic information may include speed information, angular speed information, and the like; the running environment characteristic information is a relevant parameter of the environment in which the vehicle is located during running, and for example, the running environment characteristic information may include lane line information, road boundary information, and the like. The driving characteristic information and the driving environment characteristic information are both information related to time, for example, the first vehicle acquires the driving characteristic information and the driving environment characteristic information of each time frame in a preset time period.
The first vehicle may acquire the travel characteristic information of the first vehicle, the travel characteristic information of the second vehicle, and the travel environment characteristic information of the first vehicle through its own sensor, such as a visual sensor, an inertial sensor, and the like. The first vehicle may also acquire the driving characteristic information of the first vehicle and the driving environment characteristic information of the first vehicle via its own sensors, and acquire the driving characteristic information of the second vehicle via a communication link, for example, via vehicle-to-vehicle (vehicle-to-vehicle) communication. The first vehicle may also obtain, through the server, driving characteristic information of the first vehicle, driving characteristic information of the second vehicle, and driving environment characteristic information of the first vehicle, which is not limited to this embodiment.
S202, determining predicted driving corridor information of the second vehicle according to driving characteristic information of the first vehicle and driving characteristic information of the second vehicle, wherein the predicted driving corridor information of the second vehicle is used for indicating a predicted driving area of the second vehicle.
In the present embodiment, the first vehicle can determine the predicted travel corridor information of the second vehicle based on the travel characteristic information of the first vehicle and the travel characteristic information of the second vehicle. Wherein the predicted driving corridor information can represent a possible driving area of the vehicle in a future period of time. That is, the predicted travel corridor information of the second vehicle is used to indicate the predicted travel area of the second vehicle.
For example, fig. 3 is a schematic diagram of predicted driving corridor information of the second vehicle. Referring to fig. 3, the predicted driving corridor information of the second vehicle 302 is shown as a dotted line area in fig. 3, and it can be seen from the predicted driving corridor information of the second vehicle 302 that the second vehicle 302 is about to change lane 1 to lane 2 within a future period of time, for example, 3 minutes.
Referring to fig. 3, lane 1 and lane 2 are intersecting road conditions, and a second vehicle 302 is about to travel from lane 1 to lane 2 in conjunction with the road conditions. During the period when the second vehicle 302 is going from lane 1 to lane 2, the second vehicle 302 may perform a series of preliminary actions such as decelerating and turning on the steering lamp. Further, the first vehicle 301 traveling on the lane 2 can determine the predicted travel corridor information of the second vehicle 302 based on the own travel characteristic information and the travel characteristic information of the second vehicle 302. For example, the first vehicle 301 may input its own driving characteristic information and driving characteristic information of the second vehicle 302 into the trained first prediction network to obtain predicted driving corridor information of the second vehicle. The first prediction network may be a convolutional neural network (Convolutional Neural Networks, CNN), a cyclic neural network (Recurrent Neural Network, RNN), or may be another deep learning network, a machine learning network, or the like.
In a specific embodiment, during the running process of the first vehicle, a plurality of vehicles are on the running road, the first vehicle does not need to determine the predicted running corridor information of all the vehicles, only needs to determine the second vehicle related to the running intention of the first vehicle, further determines the predicted running corridor information of the second vehicle, and the number of the second vehicles may be a plurality. Therefore, the first vehicle may determine the second vehicle from the plurality of vehicles on the driving road according to the driving characteristic information of the first vehicle, for example, the first vehicle determines the second vehicle located within a preset distance of the driving position according to the driving position of the first vehicle, and further determines the predicted driving corridor information of the second vehicle according to the driving characteristic information of the second vehicle, for example, the turn signal information, the speed information and the like of the second vehicle.
S203, inputting the driving characteristic information of the first vehicle, the driving characteristic information of the second vehicle, the driving environment characteristic information, and the predicted driving corridor information of the second vehicle into the generation countermeasure network, and determining the predicted driving corridor information of the first vehicle according to the output of the generation countermeasure network, wherein the predicted driving corridor information of the first vehicle is used for indicating the predicted driving area of the first vehicle.
In the present embodiment, after the predicted travel corridor information of the second vehicle is determined, the first vehicle may input its own travel characteristic information, the travel characteristic information of the second vehicle, the travel environment characteristic information, and the predicted travel corridor information of the second vehicle into the generated countermeasure network, and determine the predicted travel corridor information of the first vehicle for instructing the predicted travel area of the first vehicle based on the output of the generated countermeasure network.
Fig. 4 is a schematic diagram of predicted driving corridor information of the first vehicle, and after determining predicted driving corridor information of the second vehicle on the basis of fig. 3, please continue to refer to fig. 4, the predicted driving corridor information of the second vehicle indicates that the second vehicle 402 is about to go from lane 1 to lane 2 in a future period of time. The predicted driving corridor information of the first vehicle, which is determined by the first vehicle 401 according to the output of the generated countermeasure network, is shown in a black area of fig. 4, that is, the first vehicle 401 may change lanes from lane 2 to lane 3 in a future period of time, so that the path planning of the first vehicle 401 is completed, so as to avoid the second vehicle 402 from colliding and interfering with the first vehicle 401 during the lane change.
Wherein generating the countermeasure network includes a generator and a arbiter. The generator sequentially comprises an input layer, a first hidden layer, a second hidden layer, a first full-connection layer, a second full-connection layer and an output layer; the discriminator also comprises an input layer, a first hidden layer, a second hidden layer, a first full-connection layer, a second full-connection layer and an output layer in sequence.
The training process for generating the countermeasure network may be performed on a server or other computer device, for example, the server trains the generation of the countermeasure network, and in the process for generating the countermeasure network training, the server obtains a plurality of travel characteristic information samples of the historical first vehicle, travel characteristic information samples of the historical second vehicle, travel environment characteristic information samples of the historical second vehicle, and predicted travel corridor information samples of the historical second vehicle. The server inputs the travel characteristic information sample of the first vehicle, the travel characteristic information sample of the second vehicle, the travel environment characteristic information sample of the second vehicle, and the predicted travel corridor information sample of the second vehicle to the generation countermeasure network to be trained, predicts the generated countermeasure network, and outputs the predicted travel corridor information of the first vehicle.
Further, the generator inputs the predicted travel corridor information of the first vehicle to the discriminator, the discriminator discriminates the predicted travel corridor information of the first vehicle and the corresponding actual corridor information of the first vehicle, and when the discriminator confirms that the corresponding actual corridor information of the first vehicle is true from the predicted travel corridor information of the first vehicle and the corresponding actual corridor information of the first vehicle, the server continues to optimize the optimization parameters of the generator. And stopping training until the discriminator cannot discriminate true or false from the predicted running corridor information of the first vehicle and the corresponding actual corridor information of the first vehicle, and obtaining the final-use generated countermeasure network.
Further, the first vehicle may input the driving characteristic information of the first vehicle, the driving characteristic information of the second vehicle, the driving environment characteristic information, and the predicted driving corridor information of the second vehicle into the trained generated countermeasure network, and then the generator in the generated countermeasure network may output the predicted driving corridor information of the first vehicle.
The first vehicle may directly use the output of the generated countermeasure network as the predicted travel path information of the first vehicle, or may use the output of the generated countermeasure network as the predicted travel path information of the first vehicle after post-processing such as smoothing and denoising.
In the path planning method, the travel characteristic information of the first vehicle, the travel characteristic information of the second vehicle related to the travel intention of the first vehicle, and the travel environment characteristic information of the first vehicle are acquired, and further, the predicted travel corridor information of the second vehicle for indicating the predicted travel area of the second vehicle is determined based on the travel characteristic information of the first vehicle and the travel characteristic information of the second vehicle, so that the travel characteristic information of the first vehicle, the travel characteristic information of the second vehicle, the travel environment characteristic information, and the predicted travel corridor information of the second vehicle are input into the generation countermeasure network, and the predicted travel corridor information of the first vehicle for indicating the predicted travel area of the first vehicle is determined based on the output of the generation countermeasure network. Since the predicted travel path information of the second vehicle is determined based on the travel characteristic information of the first vehicle and the travel characteristic information of the second vehicle, the predicted travel path information of the second vehicle is more accurate travel path information in consideration of the travel conditions of the first vehicle and the second vehicle. Further, on the basis of the driving characteristic information of the first vehicle, the driving characteristic information of the second vehicle, the driving environment characteristic information and the predicted driving corridor information of the second vehicle, the predicted driving corridor information of the first vehicle determined by the countermeasure network is generated more accurately, the problem that in the conventional technology, only the driving environment information is acquired, and the accuracy of a lane corridor of the vehicle driving caused by planning the lane corridor of the vehicle driving according to the driving environment information is lower is solved, and the accuracy of the planned lane corridor of the vehicle driving is improved.
Fig. 5 is a schematic flow chart of determining the driving intention information of the first vehicle according to an embodiment of the present application, and referring to fig. 5, this embodiment relates to an alternative implementation of how to determine the driving intention information of the first vehicle. On the basis of the above embodiment, the path planning method further includes the following steps:
s501, determining travel intention information of the first vehicle.
In this embodiment, in order to better perform path planning, the first vehicle needs to determine own travel intention information during traveling. The travel intention information is used to indicate a travel intention of the first vehicle, the travel intention including at least one of lane change, acceleration, deceleration, jam, and emergency braking. The first vehicle may determine its own travel intention information through its own sensor, for example, a visual sensor or an inertial sensor, and may also receive the travel intention information of the first vehicle transmitted from the server.
S502, determining a region of interest from the road according to the driving intention information of the first vehicle, and taking the vehicle in the region of interest as a second vehicle.
In the present embodiment, the first vehicle determines a region of interest from the road based on own travel intention information, and the vehicle in the region of interest is taken as the second vehicle. For example, when the first vehicle accelerates in the lane 1, the vehicle in front of the first vehicle on the lane 1 may affect the path planning of the first vehicle, and the first vehicle may take the area within 500m before the first vehicle on the lane 1 is located at the moment as the area of interest, and take the vehicles a to D in the interest as the second vehicle.
According to the method and the device for determining the driving intention information of the first vehicle, the region of interest is determined from the road according to the driving intention information of the first vehicle, and the vehicle in the region of interest is used as the second vehicle, so that the calculation range of the second vehicle is accurate, and the efficiency and the accuracy of determining the predicted driving corridor information of the first vehicle are improved.
Optionally, in S501, determining the driving intention information of the first vehicle may be implemented as follows: and determining the driving intention information of the first vehicle according to the driving characteristic information and the driving environment characteristic information of the first vehicle.
In this embodiment, the first vehicle needs to determine its own travel intention information according to its own travel characteristic information and travel environment characteristic information, for example, the first vehicle determines its own travel intention information according to its own position information, speed information, lane line information, road boundary information, and the like during travel.
Optionally, the means for determining the driving intention information of the first vehicle is: the first vehicle inputs the driving characteristic information and the driving environment characteristic information of the first vehicle to the trained second prediction network so as to obtain the driving intention information of the first vehicle. The second prediction network may be a convolutional neural network (Convolutional Neural Networks, CNN) or a cyclic neural network (Recurrent Neural Network, RNN), or may be another deep learning network, a machine learning network, or the like.
According to the method and the device for determining the driving corridor information of the first vehicle, the driving intention information of the first vehicle is determined according to the driving characteristic information and the driving environment characteristic information of the first vehicle, and the driving intention information of the first vehicle can be determined according to the driving intention information of the first vehicle, so that the second vehicle can be determined according to the driving intention information of the first vehicle, the calculation range of the second vehicle is accurate, and the efficiency and the accuracy of determining the predicted driving corridor information of the first vehicle are improved.
Optionally, in some scenarios, the second vehicle may include a plurality of second vehicles, and the determining the predicted driving corridor information of the second vehicle according to the driving characteristic information of the first vehicle and the driving characteristic information of the second vehicle in S202 may be implemented as follows: for each second vehicle, determining a target vehicle related to the second vehicle according to the driving intention information of the second vehicle, and determining predicted driving corridor information of the second vehicle according to the driving characteristic information of the second vehicle, the driving intention information of the second vehicle and the driving characteristic information of the target vehicle, wherein the target vehicle is the first vehicle or other second vehicles.
In this embodiment, the number of vehicles traveling on the road may be large, and thus the number of second vehicles may be plural. For example, in the case where the number of the second vehicles is plural, assuming that the second vehicles include a vehicle a, a vehicle B, and a vehicle C, the first vehicle may determine a target vehicle related to the vehicle a based on the traveling intention information of the vehicle a, determine a target vehicle related to the vehicle B based on the traveling intention information of the vehicle B, and determine a target vehicle related to the vehicle C based on the traveling intention information of the vehicle C, the target vehicle being the first vehicle or another second vehicle. The driving intention information of the vehicles a, B and C may be obtained by the first vehicle from the server, or may be determined by the first vehicle after obtaining the driving characteristic information of the second vehicle and the driving environment characteristic information according to the sensors of the first vehicle, which is not limited in this embodiment.
Taking a driving scene of a vehicle A, a vehicle B, a vehicle C and a first vehicle in a lane 1 as an example, the vehicle A, the vehicle B and the vehicle C sequentially drive in front of the first vehicle, and when the first vehicle determines that the self-driving intention is to accelerate, the second vehicle comprises the vehicle A, the vehicle B and the vehicle C. When the first vehicle determines that the traveling intention of the vehicle a is lane 2, the vehicle related to the traveling intention of the vehicle a is a vehicle D of lane 2; when the first vehicle determines that the traveling intention of the vehicle B is the deceleration forward, the vehicle related to the traveling intention of the vehicle B is the vehicle C and the first vehicle behind; when the first vehicle determines that the traveling intention of the vehicle C is the acceleration forward traveling, the vehicles related to the traveling intention of the vehicle C are the vehicles a and B in front, that is, the target vehicle may include the vehicle D in addition to the first vehicle and the second vehicle.
Further, the first vehicle can determine predicted travel corridor information of the second vehicle based on the travel intention information of the second vehicle and the travel characteristic information of the target vehicle. That is, the predicted travel corridor information of the vehicles a to C is determined based on the travel characteristic information of the first vehicle, the travel characteristic information of the vehicles a to D, and the travel intention information of the vehicles a to C, respectively.
In a specific embodiment, the first vehicle may input the driving intention information of the second vehicle and the driving characteristic information of the target vehicle into the trained third prediction network to obtain the predicted driving corridor information of the second vehicle.
In this embodiment, for each second vehicle, a target vehicle related to the second vehicle is determined according to the driving intention information of the second vehicle, and predicted driving corridor information of the second vehicle is determined according to the driving characteristic information of the second vehicle, the driving intention information of the second vehicle, and the driving characteristic information of the target vehicle, where the target vehicle is the first vehicle or another second vehicle. Since it is also necessary to determine the target vehicle related to the traveling intention of the second vehicle, the predicted travel corridor information of the second vehicle is further determined based on the traveling characteristic information of the second vehicle, the traveling intention information of the second vehicle, and the traveling characteristic information of the target vehicle. Accordingly, the accuracy of the predicted travel corridor information of the second vehicle is further improved, thereby improving the accuracy of the predicted travel corridor information of the first vehicle, which is obtained based on the predicted travel corridor information of the second vehicle.
Fig. 6 is a schematic flow chart of determining predicted driving corridor information of a second vehicle according to an embodiment of the present application, and referring to fig. 6, this embodiment relates to an alternative implementation of how to determine predicted driving corridor information of a second vehicle. On the basis of the above embodiment, the above method for determining the predicted driving corridor information of the second vehicle according to the driving characteristic information of the second vehicle, the driving intention information of the second vehicle, and the driving characteristic information of the target vehicle includes the steps of:
S601, predicting the interaction position of the second vehicle and the target vehicle according to the driving characteristic information of the second vehicle, the driving characteristic information of the target vehicle and the driving intention information of the second vehicle.
In this embodiment, when the first vehicle determines the travel characteristic information of the second vehicle, the travel characteristic information of the target vehicle, and the travel intention information of the second vehicle, the interaction position of the second vehicle and the target vehicle can be predicted based on the travel characteristic information of the second vehicle, the travel characteristic information of the target vehicle, and the travel intention information of the second vehicle.
Continuing with the above example, with the second vehicle including the vehicle a and the target vehicle including the vehicle D, the traveling of the vehicle a is intended to change to the lane 2, and in the case where the vehicle a changes from the lane 1 to the lane 2, the first vehicle can determine the interaction position of the vehicle a and the vehicle D, for example, the area 1 where the vehicle a and the vehicle D are on the lane 2 may collide, in combination with the traveling characteristic information of the vehicle a and the traveling characteristic information of the vehicle D, for example, the speed information and the position information of the vehicle a and the vehicle D.
S602, determining predicted driving corridor information of the second vehicle according to the prediction result of the interaction position.
In this embodiment, after the interaction position of the second vehicle and the target vehicle is obtained, the first vehicle can determine predicted travel corridor information of the second vehicle according to the prediction result of the interaction position. Continuing the above illustration, if it is predicted that the vehicle a and the vehicle D collide in the area 1 on the lane 2, the driving corridor information of the vehicle a includes the driving area where the vehicle changes from the current position to the lane 2 to the area 1 on the lane 2.
The embodiment predicts the interaction position of the second vehicle and the target vehicle by using the driving characteristic information of the second vehicle, the driving characteristic information of the target vehicle and the driving intention information of the second vehicle, so as to determine the predicted driving corridor information of the second vehicle according to the prediction result of the interaction position. Because the interactive position of the second vehicle and the target vehicle can be predicted, the area needing to be avoided in the running process of the second vehicle can be known in advance, so that the accuracy of the predicted running corridor information of the second vehicle is improved, and the accuracy of the predicted running corridor information of the first vehicle is further improved.
Optionally, in an embodiment, the path planning method further includes: and determining the driving intention information of the second vehicle according to the driving characteristic information and the driving environment characteristic information of the second vehicle.
In the present embodiment, the first vehicle also needs to determine the travel intention information of the second vehicle based on the travel characteristic information of the second vehicle and the travel environment characteristic information of the second vehicle, basically the same principle as described above for determining the travel intention information of the first vehicle. For example, the first vehicle determines the traveling intention information of the second vehicle based on the position information, the speed information, the lane line information, the road boundary information, and the like of the second vehicle during traveling. For example, the first vehicle may also input the driving characteristic information and the driving environment characteristic information of the second vehicle to the trained second prediction network to obtain the driving intention information of the second vehicle.
The present embodiment determines the travel intention information of the second vehicle based on the travel characteristic information of the second vehicle and the travel environment characteristic information. Since the travel intention information of the second vehicle can be determined from the travel characteristic information of the second vehicle and the travel environment characteristic information, the target vehicle related to the travel intention of the second vehicle is determined in conjunction with the travel intention of the second vehicle, thereby improving the accuracy of the predicted travel corridor information of the second vehicle.
Optionally, the driving characteristic information includes at least one of position information, speed information, angular speed information, and acceleration information, and the driving environment characteristic information includes at least one of lane line information, road boundary information, boundary information of a drivable region, road gradient information, and road curvature information.
In the present embodiment, the acquisition of the running characteristic information and the running environment characteristic information depends on the sensor of the first vehicle. For example, the speed information, the angular speed information, the acceleration information, the road gradient information, and the road curvature information may be obtained by a sensor of the first vehicle, such as an inertial sensor. The position information can be obtained by matching the travel characteristic information with a high-precision map. The high-precision map may be a map obtained by the first vehicle from the server, or may be a map stored by the first vehicle itself. The lane line information, the road boundary information, and the boundary information of the drivable area can be obtained by their own sensors, such as visual sensors.
In a specific embodiment, the sensors of the first vehicle include 11 cameras, 5 millimeter wave radars, and 12 ultrasonic radars. The camera is used for detecting continuous images of each time frame in a preset time period, so that a target object is identified from the continuous images, and the distance between the camera and the target object, the speed of the target object and attribute information are determined by combining the millimeter wave radar and the ultrasonic radar, wherein the attribute information is used for identifying specific attributes of the target object. The object may be a second vehicle or may be a marker distinguishing the environment, such as traffic lights, road-side traffic, lane lines, etc. For example, taking the target object as the second vehicle as an example, the attribute information may include a color, a vehicle type, and the like of the second vehicle.
It is understood that when the object is a marker for distinguishing an environment, the first vehicle may determine lane line information, road boundary information, boundary information of a drivable area based on image data collected by the camera and point cloud data collected by the millimeter wave radar.
Further, since the angles and positions of the cameras, the millimeter wave radar and the ultrasonic radar on the first vehicle are different, the first vehicle can respectively perform fusion correlation on detection data obtained by the same camera, the same millimeter wave radar and the same ultrasonic radar, so that accuracy of the obtained driving characteristic information and the obtained driving environment characteristic information is improved. Of course, the first vehicle may also mutually fuse the obtained detection data of the camera, the millimeter wave radar and the ultrasonic radar for the same target object, for example, fuse the data of the second vehicle obtained by the camera with the detection data of the second vehicle obtained by the millimeter wave radar, so as to further improve the accuracy of the obtained driving characteristic information and the driving environment characteristic information.
The implementation routine driving characteristic information comprises at least one of position information, speed information, angular speed information and acceleration information, and the driving environment characteristic information comprises at least one of lane line information, road boundary information, boundary information of a driving area, road gradient information and road curvature information, so that the types of the driving characteristic information and the driving environment characteristic information are enriched, and the accuracy of predicting driving corridor information of the first vehicle is further improved.
