Various embodiments of the present invention will be described below with reference to the drawings. These embodiments are merely exemplary and are not intended to limit embodiments of the present invention.
Example 1
This embodiment 1 provides a simulation method. The simulation method can be used for simulating the whole process of stopping and leaving of the vehicle.
Fig. 1 is a schematic diagram of the simulation method of the present embodiment. As shown in fig. 1, the method includes:
103, when the speed is reduced to a specified threshold value, a parking area meeting the specified space requirement is searched;
and step 109, when the current time exceeds the preset parking ending time, the normal driving is recovered.
By the simulation method, the whole process of stopping and leaving of the vehicle can be simulated, and thus the simulation can be used for analysis and evaluation under the scene relevant to the process.
For example, the simulation method can be used for simulating a scene in which a plurality of vehicles park in a concentrated manner for passengers during a large-scale activity, so as to evaluate whether the parking area is sufficient, whether the vehicle scheduling scheme is reasonable, and the like. However, the simulation method of the present embodiment is not limited to the use in this scenario, and may be used to simulate, for example, a scenario in which a plurality of vehicles collectively park and load/unload goods near a cargo collection/distribution area.
In this embodiment, a simulation object may be constructed for a vehicle, and the simulation object may simulate the operation of the vehicle. Specifically, one simulation object may be constructed for each vehicle, and the above-mentioned step 101 and step 109 may be executed for each simulation object, so that the behavior of each vehicle can be simulated by the behavior of each simulation object.
In the present embodiment, the vehicle includes: various vehicles such as a large, medium or small passenger car, a private car, a taxi, a motorcycle, a bicycle, an electric bicycle, etc., and the vehicle may be a manned vehicle or an unmanned vehicle.
In the present embodiment, the operation flag is a flag indicating the operation state of the simulation object. The operating state of the simulation object may include, for example: normal driving, parking already/not, finding a parking space, decelerating parking, parking/not, parking failure, and the like.
In step 101, the predetermined threshold may be set according to actual conditions. The predetermined threshold may be a fixed value set in advance, or may be calculated by multiplying a normal running speed of the simulation target by a preset coefficient.
In one embodiment, the operation flag may include a first flag indicating whether the simulation object has performed parking, and in this case, the step 101 may include:
when the first flag of the simulation object indicates that the simulation object has made a stop and the current position of the simulation object is within a legal stop area, decelerating to a prescribed threshold.
Since in large activities the vehicle usually brings the passenger to the event location once, near the event start time, it is not usually necessary to stop the vehicle again after the vehicle has stopped once. Therefore, in the present embodiment, the first flag of the simulation object is used as a part of the basis for whether to decelerate to the predetermined threshold, so that the simulation object which has already simulated the parking passenger can be distinguished, and the process of simulating the parking passenger for many times can be avoided.
The first flag may indicate, for example, that the simulation object has made and has not made a parking, using True and False, respectively. The present embodiment is not limited to this, and may be expressed in other ways.
In the present embodiment, the legal parking area is a predetermined area around the parking possible position, for example, a road where the parking possible position is located.
In one embodiment, a road model and road attributes of each road may also be set in the simulation environment, and whether the current position is in a legal parking area may be determined by the road attributes, that is, whether the current position is located in a parking available road is determined.
In this embodiment, the simulation method may further include:
after slowing down the parking, or after the current time exceeds the parking end time, the first flag is configured to indicate that the simulation object has made the parking.
In this way, in the subsequent step, the simulation object can detect that it has simulated the stay-and-leave process through the first flag, and thus, the process is not simulated again.
In step 103, when the vehicle decelerates to the predetermined threshold, a parking area satisfying the predetermined space requirement is searched. In other words, in step 103, when the vehicle decelerates to the predetermined threshold, the vehicle continues to travel at the speed corresponding to the speed threshold until a parking area satisfying the predetermined space requirement is found.
In this embodiment, the step 105 may include:
when the current position of the simulation object is located within the parking area, the simulation object is moved to a parking available lane within the parking area (i.e., a parking area satisfying a prescribed space requirement).
In other words, when the current position of the simulation object is located within a parking area satisfying the prescribed space requirement, it is determined that the simulation object has found the parking area.
Parking areas that meet the specified space requirements are areas in which: the parkable lane has enough space to accommodate the current simulation object (specification attributes, which may include, for example, length, width, height, etc., may be set in advance for the corresponding simulation object based on the specification of the vehicle), and there is a buffer space for implementing the movement from the current position of the simulation object to the parkable lane. In this way, when the current position of the simulation object is located within the parking area satisfying the predetermined space requirement, it is possible to move to the parking available lane in the parking area and decelerate the parking. In china, the parkable lane in the parking area may be set as the rightmost lane in the parking area.
Fig. 2 is a schematic diagram of an implementation manner of step 105 of the present embodiment. In this embodiment, the step 105 may include (specifically, when the current position of the simulation object is located in the parking area, moving to a parking available lane in the parking area may include):
and step 203, changing the lane to the parking available lane when the current position of the simulation object is not located in the parking available lane in the parking area.
In this embodiment, the step 107 may include:
and decelerating until the speed of the simulation object is zero.
In this way, the fact that the vehicle is already in a stopped state is represented by the speed of the simulation object being zero, and it is possible to perform such actions as getting off, loading, and unloading.
In this embodiment, the parking end time may be set empirically, or may be set by the following steps:
recording the time when the speed of the simulation object is zero as the parking starting time;
determining a parking period;
and setting a parking ending time according to the starting parking time and the parking period.
The parking period may be set empirically or may be determined based on a random distribution function. The random distribution function may be a gaussian distribution function, but this embodiment does not limit this, and other random distribution functions may also be used. Therefore, the calculated parking period can accord with the random distribution function, so that the parking period accords with the real distribution rule, and the simulation result is closer to the actual situation.
In step 109, when the current time exceeds the parking end time, the normal running is resumed. And the current time exceeds the parking ending time, namely the current time is later than the parking ending time. And (4) recovering the normal running, namely running at a normal running speed which is set according to the actual condition. In this way, the process of stopping and leaving of the simulation object simulation ends.
In one embodiment, the running flag may further include a second flag indicating whether the simulation object is in a parking state, and at this time, the simulation object may further perform the following steps:
configuring a second flag of the simulated object to indicate a parking state when the speed of the simulated object is zero;
the simulated object prohibits changing lanes when the second flag of the simulated object indicates that the simulated object is in a stopped state.
In the present embodiment, the parked state means a state in which the vehicle is stopped.
In this way, it is possible to detect whether or not the simulation object is in a stopped state by the second flag, and since the vehicle should not move when the vehicle is in the stopped state and other related operations such as getting off a passenger, loading or unloading goods, etc. are normally performed, it is possible to make the simulation closer to the actual situation by prohibiting the simulation object from changing lanes when it is detected that the simulation object is in the stopped state.
The second flag may indicate that the simulation object is in a parked state and not in a parked state, for example, using True and False, respectively. The present embodiment is not limited to this, and may be expressed in other ways.
In this embodiment, the simulation method may further include:
the second flag is configured to indicate that the vehicle is not in the parking state when the current time exceeds the parking end time.
In this way, the second flag can be updated in time.
In this embodiment, the simulation object may also be caused to perform:
when the simulation object has moved to the destination and a parking area satisfying the specified space requirement is not found, the simulation object is recorded as a parking failure.
In this embodiment, the simulation object may be recorded as a parking failure in various ways. For example, a third flag indicating parking success/failure may be set for the simulation object, or an additional data record may be set in the simulation environment for recording whether the parking of each simulation object is successful. Also, the present embodiment is not limited in the above manner.
Fig. 3 is another schematic diagram of the simulation method of the present embodiment. As shown in fig. 3, the method may include:
and step 314, recovering the normal running.
In the above simulation method, the initial values of the first flag and the second flag may be both configured to False, that is, the initial state of the simulation object may be configured such that no parking is performed and lane change is allowed. In addition, during execution of the method, it may be periodically determined whether the second flag is True, and if the second flag is True, lane change is prohibited until lane change is permitted again when the second flag is False.
Fig. 3 shows a specific embodiment of the present embodiment, but it is not limited to the present embodiment.
Through the simulation method of the embodiment, the stopping and leaving processes of the vehicle can be simulated for relevant analysis and evaluation.
