Detailed Description
In the following, only certain exemplary embodiments are briefly described. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.
Referring to fig. 1, an embodiment of the invention provides a method for simulating an autonomous vehicle. The embodiment includes steps S100 to S400, which are specifically as follows:
s100, acquiring drive test data in the driving process of the data acquisition vehicle, wherein the drive test data comprises an actual driving track of the data acquisition vehicle.
The drive test data may include driving data of the vehicle and all obstacles, which can be acquired by the sensors of the data acquisition vehicle, traffic road environment, and the like. The obstacles may include pedestrians, obstacle vehicles, and the like.
S200, reproducing the simulation environment of the automatic driving vehicle by using the drive test data.
Because the drive test data can include the drive test data of the simulation targets of the data acquisition vehicles, pedestrians and various obstacle vehicles, according to the acquisition time sequence of the data acquisition vehicles, the organization form of the acquired drive test data of the simulation targets is as follows: d = { D t1 ,D t2 ,…,D tn Where i =1,2, \ 8230;, n, D ti And collecting the data measured by the vehicle for the data at the moment ti. D ti Tissue form D ti ＝{D ti,a1 ,D ti,a2 ,…,D ti,ak Where j =1,2, \8230, k. D ti,aj The data is the data of the jth simulation target at time ti.
In the simulation, due to the asynchronous clocks, the time of each simulation frame and the time of each drive test data frame are not completely overlapped, and operations such as data smoothing and interpolation can be performed, so that the data organization form used by the simulation is a spatial sequence, namely, D = { D = a1 ,D a2 ,…,D am In which D is ap For the data of the pth simulation target, p =1,2, \8230;, m. For each simulation target data at each moment, the organization form is D ap ＝{D ap,t1 ,D ap,t2 ,…,D ap,ts In which D is ap,tq Q =1,2, \ 8230;, s for the data of the pth simulation target at the qth instant.
Therefore, D = { D can be used a1 ,D a2 ,…,D am And reproducing the running track of each simulation target in the simulation environment. Meanwhile, the automatic driving vehicle (simulated data acquisition vehicle) can determine the driving state of each obstacle vehicle at the next moment by using the running strategy of the automatic driving vehicle and the driving state of each obstacle vehicle. I.e. normal simulationIn the process, the automatic driving vehicle runs in an automatic driving mode, and the obstacle vehicle runs in a fixed track mode.
S300, in the simulation environment, comparing the running track of the automatic driving vehicle on the current running road section with the deviation between the actual running track of the data acquisition vehicle.
In some embodiments, at each time the autonomous vehicle is operating in the simulated environment, the travel trajectory of the travel segment in which the autonomous vehicle is currently located may be determined and compared to the actual trajectory of the data-capturing vehicle in the same travel segment, e.g., whether the trajectory lines are consistent, whether the status of the vehicle is consistent, etc. The state of the vehicle may include going straight, turning, changing lanes, following a lead vehicle, etc. Of course, the state of the vehicle may be clutch opening, brake opening, steering wheel angle, or the like, or a specific position of the vehicle in the travel route, travel speed, or the like. Therefore, the embodiment of the invention can judge whether the deviation of the running track exceeds the tolerance or not from multiple dimensions.
S400, if the deviation exceeds the preset deviation tolerance, the simulation is suspended.
For example, if the distance between the driving position of the autonomous vehicle and the driving position of the data collection vehicle is more than 80 meters in the same road section, the deviation tolerance of the user is considered to be exceeded. If such a condition is met, the simulation may be considered distorted and the distortion exceeds a tolerable level, and the simulation may be suspended. The simulation is not continuously carried out according to the current simulation state, so that the simulation efficiency can be improved, and the meaningless simulation is avoided under the distortion condition.
In the embodiment of the invention, in the simulation environment of the automatic driving vehicle reproduced by using the drive test data, the deviation between the running track of the automatic driving vehicle on the current running road section and the actual running track of the actual data acquisition vehicle is compared aiming at each moment, and if the deviation exceeds the preset deviation tolerance, the simulation is suspended, so that the excessive distortion of the subsequent simulation is avoided, and the utilization rate of simulation resources is improved.
In some embodiments, as shown in fig. 2, the method for simulating an autonomous vehicle according to this embodiment may further include:
and S500, restarting the simulation after the running state of the automatic driving vehicle on the current running road section is restored to the actual running state of the data acquisition vehicle on the current running road section.
Because the simulation scene and the simulation effect before the current driving road section are fit with the actual environment, the driving condition of the road section before the current driving road section can be continuously simulated from the current road section without re-simulation, thereby improving the simulation efficiency. In order to reduce the distortion degree of the subsequent simulation and ensure that the deviation tolerance of a user is not exceeded, the driving state of the automatic driving vehicle on the current driving road section can be restored to the actual driving state of the data acquisition vehicle on the current driving road section.
In some embodiments, the driving conditions may include at least one of: the driving position, the driving speed, the driving course angle, the driving decision parameter and the like.
In the embodiment of the invention, whether the deviation of the simulated driving track exceeds the tolerance or not can be judged in multiple dimensions. If the simulation scene exceeds the preset threshold value, the simulation scene can be dynamically cut off, and the simulation data is restarted after the simulation data is restored to the data of the original data acquisition vehicle at the moment. Therefore, the restoration of a real scene and the iteration of a closed-loop algorithm based on the restoration can be supported.
Closed loop means that the control decision of the algorithm can be used as the input of a power system of the automatic driving vehicle to influence the motion of the automatic driving vehicle, and the change of the motion state of the automatic driving vehicle can influence the control decision of the algorithm to form a closed loop, which is different from an open loop. The control decision of the open loop algorithm is based on the running state of the automatic driving vehicle, but the control decision is not input into a power system and does not influence the motion of the vehicle, and the motion state of the vehicle plays back data recorded in the route measurement.
The closed-loop algorithm iteration refers to that under a closed-loop state, problems (such as collision risks, stagnation and the like) existing in the algorithm are found, after the algorithm is optimized, verification is carried out in simulation to see whether the problems are solved, if not, optimization is continued, and iteration is carried out repeatedly until the problems are solved.
In the embodiment of the invention, the tolerance can be flexibly adjusted according to actual conditions. Thus, in some embodiments, the process of adjusting the offset tolerance, as shown in fig. 3, may include:
and S610, determining the weather condition of the simulation environment by using the drive test data.
The drive test data can comprise the real environment where the data acquisition vehicle shot by the automobile data recorder is located. If the captured image includes dense water that falls down, it can be determined that it is raining at the present time. If the captured image includes snowfield with white flowers, it can be determined that snow exists on the road of the current road section. If the captured image includes light but the front is dark, it can be determined that the current time is at night. The image can be identified by using the identification model, and the weather condition of the simulation environment can be obtained. The recognition model can be generated by training according to a large number of sample images and training data marked on weather conditions of the sample patterns. And determining the weather condition of the simulation environment according to the identified weather condition, and then restoring according to the determined weather condition in the process of restoring the simulation environment. Wherein, the identification model is used for identifying the weather condition, so that the identification accuracy and efficiency can be improved.
And S620, determining the offset tolerance according to the weather condition. The worse the weather, the less tolerant to drift.
For example, if in the case of rainy or snowy weather, nighttime, or the like, the distance of tolerance of the offset position on the same road section can be appropriately shortened. If under sunny, daytime, etc., the tolerance distance of the offset position at the same road section can be appropriately lengthened.
In some embodiments, the offset tolerance may also be determined based on the sensitivity of the data collector of the data collection vehicle. Specifically, as shown in fig. 4, the setting process of the offset tolerance may include steps S710 and S720 as follows:
and S710, acquiring the sensitivity of a data acquisition device of the data acquisition vehicle. The data collector can comprise sensors such as a driving recorder, a speed detector and a gyroscope.
And S720, determining the offset tolerance according to the sensitivity. The higher the sensitivity, the less offset tolerant.
The embodiment of the invention can flexibly adjust the deviation tolerance, so that the simulation environment is more fit with the real environment.
