All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
According to an embodiment of the present application, there is provided an embodiment of a control method for a vehicle, it should be noted that the steps shown in the flowchart of the drawings may be executed in a computer system such as a set of computer executable instructions, and that while a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that here.
Fig. 1 is a flowchart of a control method of a vehicle according to an embodiment of the present application, as shown in fig. 1, the method including the steps of:
step S102, acquiring images in front of a current vehicle in real time in the process that the current vehicle runs according to an automatic driving mode;
step S104, identifying whether a traffic signal lamp and a stop line exist in the image;
step S106, under the condition that a traffic signal lamp and a stop line exist in the image, determining the indication state of the traffic signal lamp and the distance between the current vehicle and the stop line, wherein the stop line and the current vehicle are positioned on the same side of the traffic signal lamp;
and step S108, controlling the running speed of the current vehicle according to the indication state and the distance of the traffic signal lamp.
Through the steps, the purpose of controlling the automatic driving vehicle to safely pass through the intersection provided with the traffic signal lamp is achieved by identifying the indicating state of the traffic signal lamp and then controlling the running speed of the automatic driving vehicle according to the indicating state of the traffic signal lamp and the distance between the current vehicle and the stop line, and therefore the technical effect of improving the running safety of the automatic driving vehicle when the automatic driving vehicle passes through the intersection provided with the traffic signal lamp is achieved.
According to an alternative embodiment of the present application, step S108 is implemented by: if the indication state of the traffic light is red, determining whether the traffic light displays the remaining time; if the traffic signal lamp does not display the remaining time, controlling the current vehicle to run at a reduced speed, and stopping the current vehicle from running before the current vehicle reaches a stop line; and if the traffic signal lamp displays the remaining time, controlling the running speed of the current vehicle according to the remaining time and the distance of the red light.
In this step, if the traffic signal lamp only displays three indication states of red light, yellow light and green light and does not have the function of displaying time, for the sake of safety, if the indication state of the traffic signal lamp is recognized as the red light, the current vehicle is controlled to decelerate, and the vehicle is guaranteed to stop running before reaching the stop line.
If the traffic signal lamp not only displays three indication states of red light, yellow light and green light, but also has the function of displaying time, if the indication state of the traffic signal lamp is identified to be the red light, the remaining time of the red light needs to be further identified, and then the running state of the vehicle is controlled according to the remaining time of the red light.
According to another alternative embodiment of the present application, the controlling of the driving speed of the present vehicle according to the remaining time and distance of the red light includes: determining a first remaining time for a red light; comparing a first product of a current vehicle's travel speed and a first remaining time with the distance; if the first product is larger than or equal to the distance, controlling the current vehicle to run at a reduced speed, and stopping the current vehicle from running before the current vehicle reaches a stop line; and if the first product is smaller than the distance, controlling the current vehicle to continue to run according to the current running speed.
For example, the remaining time of the red light is 10s, the current vehicle has a traveling speed of 40Km/h, the distance between the current vehicle and the stop line is 50m, and if the vehicle travels at a constant speed according to the current speed, the distance traveled before the red light changes is 111 m. If the vehicle is controlled to continue to run according to the current speed, the vehicle can cross the stop line before the red light changes into the light, and the traffic regulation can be violated, and at the moment, the vehicle is controlled to run at a reduced speed, so that the vehicle stops running before reaching the stop line.
The distance between the current vehicle and the stop line is 120m, if the vehicle is controlled to continue to run according to the current speed, the vehicle cannot cross the stop line before the red light is changed into the light, namely, after the traffic signal light is changed from the red light into the green light, the vehicle does not reach the stop line, the running speed of the vehicle does not need to be changed at the moment, and the vehicle is controlled to continue to run according to the current running speed.
By the method, the driving speed of the vehicle passing through the intersection can be controlled according to the display time of the traffic signal lamp, and the efficiency of the automatic driving vehicle passing through the intersection can be improved on the basis of ensuring the driving safety of the automatic driving vehicle passing through the intersection.
In some optional embodiments of the present application, step S108 may also be implemented by: if the indication state of the traffic signal lamp is green, determining whether the traffic signal lamp displays the remaining time; if the traffic signal lamp does not display the remaining time, controlling the current vehicle to continue to run according to the current running speed; and if the traffic signal lamp displays the remaining time, controlling the running speed of the current vehicle according to the remaining time and the distance of the green light.
In this step, if the traffic signal lamp only displays three indication states of red light, yellow light and green light, the traffic signal lamp does not have the function of displaying time, and if the indication state of the traffic signal lamp is identified to be the green light, the vehicle is controlled to continue to run according to the current running speed.
If the traffic signal lamp has the function of displaying time besides three indication states of red light, yellow light and green light, if the indication state of the traffic signal lamp is identified to be green light, the remaining time of the green light needs to be further identified, and then the driving state of the vehicle is controlled according to the remaining time of the green light.
According to another alternative embodiment of the present application, the controlling of the driving speed of the present vehicle according to the remaining time and distance of the green light includes: determining a second remaining time for a green light; comparing a second product of the current vehicle's travel speed and the second remaining time with the distance; if the second product is larger than the distance, controlling the current vehicle to continuously run according to the current running speed; and if the second product is less than or equal to the distance, controlling the current vehicle to run at a reduced speed so that the current vehicle stops running before reaching the stop line.
For example, the remaining time of the green light is 10s, the current vehicle has a traveling speed of 40Km/h, the distance between the current vehicle and the stop line is 50m, and if the vehicle travels at a constant speed according to the current speed, the distance traveled before the green light changes to be 111 m. If the vehicle is controlled to continue to run according to the current speed, the vehicle can cross the stop line before the light is changed from green, and the running speed of the vehicle does not need to be changed at the moment, so that the vehicle can be controlled to continue to run according to the current running speed.
The distance between the current vehicle and the stop line is 120m, if the vehicle is controlled to continue to run according to the current speed, the vehicle cannot cross the stop line before the red light changes into the yellow light, namely after the traffic signal light changes from the green light to the yellow light, the vehicle does not reach the stop line, and the vehicle is controlled to decelerate to run at the moment so that the vehicle stops running before reaching the stop line.
According to an alternative embodiment of the present application, before executing step S108, the driving state of the target vehicle located on the lane adjacent to the lane where the current vehicle is located and having the same driving direction as the current vehicle needs to be acquired; judging whether the running state of the target vehicle is the same as that of the current vehicle; if the running state of the target vehicle is the same as that of the current vehicle, controlling the running speed of the current vehicle according to the indication state and the distance of the traffic signal lamp; and if the running state of the target vehicle is different from that of the current vehicle, re-determining the indication state of the traffic signal lamp.
By acquiring the running state of the vehicle which is adjacent to the lane where the current vehicle is located and has the same running direction as the current vehicle, if the running state of the vehicle is the same as the running state of the current vehicle, the indication state of the traffic signal lamp acquired by the current vehicle is correct, otherwise, the indication state of the traffic signal lamp acquired by the current vehicle is wrong, and the indication state of the traffic signal lamp needs to be acquired again.
By the method, the accuracy of the indication state of the traffic signal lamp acquired by the current vehicle can be improved, and the technical effect of driving safety when the automatic driving vehicle passes through the intersection is further improved.
