Before discussing exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart depicts operations as a sequential process, many of the operations can be performed in parallel, concurrently, or at the same time. Furthermore, the order of the operations may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figures. The processes may correspond to methods, functions, procedures, subroutines, and the like.
In the embodiments of the present invention, the terms "first," "second," and the like are used to distinguish between different elements from each other by name, but do not indicate spatial arrangement or time sequence of the elements, and the elements should not be limited by the terms. The term "and/or" includes any and all combinations of one or more of the associated listed terms.
In embodiments of the present invention, the singular forms "a," an, "and" the "include plural referents and should be construed broadly to mean" one "or" one type "and not limited to" one "or" another; furthermore, the term "comprising" is to be interpreted as including both the singular and the plural, unless the context clearly dictates otherwise. Furthermore, the term "according to" should be understood as "at least partially according to … …", and the term "based on" should be understood as "based at least partially on … …", unless the context clearly indicates otherwise.
It will be understood that when an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or intervening elements may be present. In contrast, when an element is referred to as being "directly connected" or "directly coupled" to another element, there are no intervening elements present. Other words used to describe relationships between units (e.g., "between" versus "directly between," "adjacent to" versus "directly adjacent to," etc.) should be interpreted in a similar manner.

For example, two figures shown in succession may in fact be executed substantially concurrently or the figures may sometimes be executed in the reverse order, depending upon the functionality/acts involved.
Various implementations of embodiments of the present invention are described below with reference to the accompanying drawings. These implementations are merely illustrative and not limiting of the embodiments of the present invention.
Example 1
The present embodiment 1 provides a simulation method. The simulation method can be used for simulating the whole process of stopping and leaving the vehicle.
Fig. 1 is a schematic diagram of a simulation method of the present embodiment. As shown in fig. 1, the method includes:
step 101, decelerating to a specified threshold according to an operation mark indicating the operation state of the simulation object and the current position of the simulation object;
step 103, searching a parking area meeting the requirement of a specified space when the speed is reduced to a specified threshold value;
step 105, moving to a parkable lane in the parking area;
step 107, decelerating and stopping;
and 109, when the current time exceeds the preset stopping end time, the normal running is resumed.
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 in a scene related to the process.
For example, the simulation method can be used for simulating a scene that a plurality of vehicles are parked and alight in a concentrated manner during large-scale activities so as to evaluate whether parking areas are sufficient, whether a vehicle scheduling scheme is reasonable and the like in the scene. However, the simulation method of the present embodiment is not limited to this scenario, and may be used to simulate a scenario in which a plurality of vehicles are parked and loaded and unloaded in a lump in the vicinity of a cargo distribution area, for example.
In this embodiment, a simulation object may be constructed for a vehicle such that the simulation object simulates the operation of the vehicle. Specifically, one simulation object may be built for each vehicle, and the above steps 101-109 are performed 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, a vehicle includes: various vehicles such as large, medium or small buses, private cars, taxis, motorcycles, bicycles, electric bicycles, and the like, and the vehicle may be a manned vehicle or an unmanned vehicle.
In the present embodiment, the running flag is a flag indicating the running state of the simulation object. The running state of the simulation object may include, for example: normal travel, park/no park, find parking space, slow down park, park/no park, park miss, etc.
In step 101, a predetermined threshold may be set according to the actual situation. The predetermined threshold value may be a fixed value set in advance, or may be calculated by multiplying the normal running speed of the simulation target by a predetermined coefficient.
In one embodiment, the running flag may include a first flag indicating whether the simulation object has been parked, and the step 101 may include:
the method includes decelerating to a prescribed threshold when a first flag of a simulated object indicates that the simulated object has been parked and a current location of the simulated object is within a legal parking area.
Since in large-scale campaigns, a vehicle typically brings passengers to a campaigns site at a time near the start time of the campaigns, it is not generally necessary to park the vehicle again for a pick-up after the vehicle has been parked for a pick-up. Thus, in this embodiment, by taking the first flag of the simulation object as a part of the basis of whether to decelerate to the prescribed threshold, it is possible to distinguish the simulation object that has already simulated a parking deposit, avoiding the process of simulating a parking deposit multiple times.
The first flag may indicate that the simulation object has been parked and not parked, respectively, using True and False, for example. The present embodiment is not limited thereto, and may be expressed in other ways.
In the present embodiment, the legal parking area is a predetermined area around the parkable position, for example, a road on which the parkable position is located.
In one embodiment, the road model and the road attribute of each road may also be set in the simulation environment, and whether the current position is in the legal parking area may be determined by the road attribute, that is, whether the current position is in the parkable road may be determined.
In this embodiment, the above simulation method may further include:
after the deceleration parking, or after the current time exceeds the parking end time, a first flag is configured to indicate that the simulation object has been parked.
In this way, in a subsequent step, the simulation object can detect that it has simulated the stay and leave process by the first flag, so that the process is not simulated again.
In step 103, when the vehicle is decelerated to a predetermined threshold, a parking area satisfying a predetermined space requirement is searched for. In other words, in step 103, when decelerating to the predetermined threshold, the vehicle continues to travel at a 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 in the parking area, the simulation object moves to a parkable lane in the parking area (namely, the parking area meeting the specified space requirement).
In other words, when the current position of the simulation object is located within the parking area satisfying the predetermined space requirement, it is determined that the simulation object has found the parking area.
The parking area satisfying the prescribed space requirement is such an area: the stoppable lane has enough space to accommodate the current simulation object (specification attributes may be set in advance for the corresponding simulation object based on the specification of the vehicle, which may include, for example, length, width, height, etc.), and there is a buffer space for implementing movement from the current position of the simulation object to the stoppable lane. In this way, when the current position of the simulation object is located in the parking area satisfying the predetermined space requirement, the vehicle can move to the parkable lane in the parking area and can be parked at a reduced speed. 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 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 parkable lane in the parking area may include:
step 201, judging whether the current position of the simulation object is positioned in a stoppable lane in the stoppable area;
step 203, changing the road to the stoppable lane when the current position of the simulation object is not located in the stoppable lane in the stoppable area.
In this embodiment, the step 107 may include:
and decelerating until the speed of the simulation object is zero.
In this way, by characterizing that the vehicle is already in a stopped state by the speed of the simulation object being zero, such actions as downloading and loading can be performed.
In this embodiment, the above-described 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 start time;
determining a parking period;
a parking end time is set based on the start parking time and the parking period.
The parking period may be empirically set or may be determined based on a random distribution function. The random distribution function may be a gaussian distribution function, but the present embodiment is not limited thereto, and other random distribution functions may be used. Therefore, the calculated parking period accords with the random distribution function, and therefore accords with the distribution rule in reality, and the simulation result is closer to the actual situation.
In step 109, when the current time exceeds the stop end time, normal running is resumed. The current time exceeds the parking end time, namely, the current time is later than the parking end time. The normal running is resumed, that is, the running is performed at a normal running speed, which is set according to the actual situation. Thus, the process of stopping and leaving the simulation object is ended.
In one embodiment, the running flag may further include a second flag indicating whether the simulation object is in a stopped state, and at this time, the simulation object may further perform the steps of:
configuring a second flag of the simulated object to indicate a stopped 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, being in a stopped state means that the vehicle has stopped.
In this way, by the second flag, it is possible to detect whether or not the simulation object is in the stopped state, and since the vehicle is normally performing other related operations such as a passenger, loading and unloading, and the like while in the stopped state, the vehicle should not move, and therefore, when it is detected that the simulation object is in the stopped state, the simulation object is prohibited from changing lanes, and thus, the simulation can be made closer to the actual situation.
The second flag may indicate that the simulation object is in a parked state and not in a parked state, respectively, using True and False, for example. The present embodiment is not limited thereto, and may be expressed in other ways.
In this embodiment, the above simulation method may further include:
the second flag is configured to indicate that the vehicle is not parked 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 execute:
when the simulation object has moved to the destination and a parking area satisfying the prescribed 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 success/failure of parking may be set for the simulation objects, or additional data records may be set in the simulation environment for recording whether each simulation object is successful in parking. 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:
step 301, determining whether the first flag is not True; if the first flag is not True (i.e., false), then step 302 is performed, otherwise step 313 is performed;
step 302, judging whether the current position of the simulation object is in a legal parking area; if the current position is within the legal parking area, executing step 303, otherwise returning to step 302;
step 303, decelerating to a prescribed threshold value;
step 304; determining whether a current position of the simulation object has reached a destination; if the current location has reached the destination, step 306 is performed, otherwise step 305 is performed;
step 305; judging whether the current position of the simulation object is positioned in a parking area meeting the requirement of a specified space; if the current location is within the parking area, then step 307 is performed, otherwise step 303 is returned;
step 306, recording the simulation object as a parking failure;
step 307, determining a parking period;
step 308, moving to the parking area in the parking lane;
step 309, decelerating;
step 310, determining whether the speed is zero; if the speed is zero, go to step 311, otherwise return to step 309;
step 311, recording the current time as a parking start time, setting a parking end time according to the parking start time and the parking period, configuring a first sign to indicate True, and configuring a second sign to True;
step 312, determining whether the current time exceeds the parking end time; if the current time exceeds the parking end time, executing step 313, otherwise returning to step 312;
step 313, configuring the second flag as False;
step 314, resume normal running.
In the above simulation method, the initial values of the first flag and the second flag may both be configured as False, that is, the initial state of the simulation object may be configured to be that no parking has been performed and that the lane change is allowed. In addition, during the 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 the second flag is False, and lane change is again permitted.
Fig. 3 shows a specific implementation of the present embodiment, but this is not a limitation of the present embodiment.
By the simulation method of the embodiment, the stay and leave process of the vehicle can be simulated for relevant analysis and evaluation.
