The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
In addition, it should be understood that the term "and/or" herein is merely one type of association relationship that describes an associated object, meaning that three relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
FIG. 1 is a flow chart of a first embodiment of a method for controlling a vehicle as described herein. As shown in fig. 1, the following detailed implementation is included.
In 101, a travel path of at least one trip of the vehicle is acquired and a green wave speed of the travel path is determined.
At 102, the travel speed of the vehicle is controlled based on the determined green wave speed.
In the embodiment of the method, the driving assistance function is integrated with the green wave passing, and the vehicles are assisted to continuously pass through a plurality of traffic light intersections without stopping at a certain speed, so that the passing efficiency is improved, and the like.
When a vehicle needs to go to a certain destination, destination information can be obtained firstly, such as destination information input/set by a user can be obtained, and path planning can be performed according to the destination information, such as that the current position of the vehicle is "Beijing university of industry", the destination is "Qinghua university", a running path from "Beijing university of industry" to "Qinghua university" can be planned for the journey, and the running path may include a plurality of traffic light intersections.
As described in 101, the green wave speed of the travel path may be determined. Specifically, in the process that the vehicle travels along the travel path, the green wave speed determined by the cloud platform can be acquired, the green wave speed is the vehicle travel speed capable of continuously passing through the N traffic light intersections in front, N is a positive integer greater than one, N is less than or equal to M, and M is a positive integer greater than one, and the number of the traffic light intersections on the travel path through which the vehicle does not pass is represented.
That is, assuming that 10 traffic light intersections exist on the planned driving path, for convenience of description, the traffic light intersections 1 to 10 are respectively referred to according to the driving sequence, and then the vehicle can acquire the green wave speed from the cloud platform before passing through any one of the traffic light intersections 1 to 9.
Assuming that the green wave speed is obtained before passing through the traffic light intersection 1, the value of N is 3, the green wave speed is the speed A, then the vehicle can continuously pass through the 3 traffic light intersections 1, 2 and 3 according to the speed A, assuming that the green wave speed is obtained after passing through the traffic light intersection 4 and before passing through the traffic light intersection 5, the value of N is 4, the green wave speed is the speed B, then the vehicle can continuously pass through the 4 traffic light intersections 5, 6, 7 and 8 according to the speed B. The speed at which the vehicle passes through other traffic light intersections is not limited.
It should be noted that, the above manner/strategy for acquiring the green wave velocity is only an example, and is not used to limit the technical solution of the present application, and how and when the green wave velocity is acquired may be determined according to actual needs.
Through the processing, the vehicle can acquire the green wave speed matched with the actual situation in time, and the passing efficiency is improved.
As described in 102, the travel speed of the vehicle may be controlled based on the green wave speed. The vehicle may be automatically controlled to travel based on the green wave speed, such as when the vehicle is in an autonomous driving mode.
When the vehicle is in the manual driving mode, the green wave speed can be used as the recommended vehicle speed to be prompted to the driver, so that the driver can manually control the vehicle to run according to the recommended vehicle speed.
The vehicle in the manual driving mode may refer to that the vehicle itself is an automatic driving vehicle, but is currently in the manual driving mode, or may refer to that the vehicle itself is a manual driving vehicle, and only the manual driving mode can be adopted. In any case, when the vehicle is in the manual driving mode, the green wave speed can be prompted to the driver, namely, vehicle-end prompting is performed, for example, the prompting can be performed through a screen or through voice, and the specific mode is not limited, so that the driver can manually control the vehicle to run according to the recommended vehicle speed.
That is to say, the scheme that this application was described is applicable to both automatic driving vehicle, also can be applicable to manual driving vehicle, has extensive suitability.
FIG. 2 is a flow chart of a second embodiment of a method for controlling a vehicle as described herein. As shown in fig. 2, the following detailed implementation is included.
In 201, for a travel path of at least one trip of the vehicle, a green wave speed of the travel path is determined.
At 202, a green wave speed is transmitted to the vehicle, the green wave speed being used as the travel speed of the vehicle.
The method comprises the steps that when a vehicle runs according to a running path, the green wave speed can be determined, the green wave speed is the running speed of the vehicle which can continuously pass through N traffic light intersections in front, N is a positive integer larger than one, N is smaller than or equal to M, and M is a positive integer larger than one, and the number of the traffic light intersections on the running path, which are not passed by the vehicle, is represented.
As a possible implementation manner, a first traffic light intersection on the driving path may be used as a to-be-processed intersection, and for the to-be-processed intersection, the following first processing is performed: acquiring a green wave speed before the vehicle does not pass through the intersection to be processed; if the acquisition is successful, after the vehicle continuously passes through the N traffic light intersections, if at least two traffic light intersections still exist in front of the vehicle, the next traffic light intersection is taken as an intersection to be processed, and the first processing is repeatedly executed, or if at least two traffic light intersections still exist in front of the vehicle, the next traffic light intersection is taken as an intersection to be processed, and the first processing is repeatedly executed; if the acquisition fails, after the vehicle passes through the intersection to be processed, if at least two traffic light intersections still exist in front of the intersection, the next traffic light intersection is taken as the intersection to be processed, and the first processing is repeatedly executed.
The above process can be exemplified as follows.
Assuming that 10 traffic light intersections coexist on the planned path, for convenience of expression, the planned path is respectively called a traffic light intersection 1-a traffic light intersection 10 according to the driving sequence.
After the vehicle is started, if the vehicle is away from the traffic light intersection 1 by a preset distance (specific value can be determined according to actual needs), the green wave speed can be acquired, and if the acquisition fails, namely the vehicle cannot continuously pass through a plurality of traffic light intersections in front at the green wave speed, the green wave speed can be acquired again after the vehicle passes through the traffic light intersection 1.
Assuming that the green wave speed is successfully obtained again after passing through the traffic light intersection 1, and the obtained green wave speed is a speed (vehicle speed) a, in an ideal case, if the value of N is 9, the vehicle can directly and continuously pass through the subsequent 9 traffic light intersections at the obtained green wave speed, that is, continuously travel the subsequent whole distance, if the value of N is 3, the vehicle can obtain the green wave speed again after continuously passing through 3 traffic light intersections, namely, the traffic light intersection 2, the traffic light intersection 3 and the traffic light intersection 4 according to the speed a, the success of obtaining can be obtained, the failure of obtaining can be obtained, correspondingly, the subsequent processing can be respectively carried out according to a corresponding mode, or if the value of N is 3, the green wave speed can be obtained again after each time the vehicle passes through one traffic light intersection, for example, after the vehicle passes through the traffic light intersection 2 according to the speed a, the green wave velocity is obtained again, and the obtained green wave velocity may still be the velocity a and the value of N is 2, or the obtained green wave velocity may also be the velocity B and the value of N is 4.
When the green wave speed is obtained, the green wave speed can be obtained according to the timing period of the traffic light intersection where the vehicle does not pass on the driving path and the current state information, and the green wave speed is usually within a preset vehicle driving speed range.
For any traffic light intersection, the timing cycle information can include information such as the display duration of each color signal light of the traffic light intersection, and the current state information can include information such as the color and the displayed duration of the currently displayed signal light of the traffic light intersection.
The method and the device for determining the green wave speed are not limited and can be determined according to actual needs.
For example, as a possible implementation manner, a vehicle driving speed range can be set at first, assuming that the driving speed range is 40KM/H-60KM/H, then 60KM/H can be used as a predicted passing speed at first, it is determined whether a green light can pass through a first traffic light intersection in front at the predicted passing speed from a current position, it can be determined by combining a timing period of the traffic light intersection and current state information, if so, it can be continuously determined whether a green light can pass through a second traffic light intersection in front at the predicted passing speed, and so on, the traffic light intersections in front are traversed sequentially, once a certain traffic light intersection cannot pass through, traversal is ended, and the traffic light intersections in front of the traffic light intersection which cannot pass through can be used as N traffic light intersections which can pass through continuously, assuming that the value of N is 3, and the predicted passing speed can be used as a green wave speed, if all the traffic light intersections in front can pass through the intersection, the value of N is equal to the number of all the traffic light intersections in front, if a plurality of traffic light intersections which can pass through continuously can not be found according to the processing mode, the predicted passing speed of-5 KM/h can be used as a new predicted passing speed, and the processing is repeatedly carried out until the predicted passing speed is less than 40 Km/h.
Based on the above description, fig. 3 is a schematic diagram of an overall implementation process of the method for controlling the vehicle according to the present application. As shown in fig. 3, taking the vehicle as an autonomous vehicle and currently in an autonomous driving mode as an example, after a destination is input, path planning and behavior decision can be performed according to the existing manner, and the cloud platform can determine a green wave speed, where the green wave speed is a vehicle driving speed that can continuously pass through N traffic light intersections ahead, where N is a positive integer greater than one, the fusion sensing and recognition system of the vehicle can fuse the acquired green wave speed with other environment sensing data (such as map traffic operation data, surrounding vehicle data, pedestrian position data, and the like) to generate a Control execution result of the driving speed and generate a corresponding operation instruction, and the vehicle Electronic Control Unit (ECU) and the whole vehicle working component execute the operation instruction, and finally drive according to the green wave speed and continuously pass through the N traffic light intersections.
Fig. 4 is a schematic diagram of a sequence of 3 traffic light intersections according to the method of the present application. As shown in fig. 4, the vehicle can pass through the 3 traffic light intersections shown in the figure in succession at a green wave speed.
