Embodiment 1

[0066] An embodiment of the present invention provides a speed control method. figure 1 It is a schematic flowchart of a speed control method according to an embodiment of the present invention. Such as figure 1 As shown, the method includes the following steps:

[0067] Step 101: After determining that the vehicle enters the preset area of ​​the intersection, determine the first duration according to the first speed, the second speed and the first distance of the vehicle;

[0068] Here, the first speed is the current driving speed of the vehicle; the second speed is the maximum speed limited by the road section; the first distance is the distance between the current position of the vehicle and the stop line; the second A duration represents the duration required for the vehicle to reach the stop line at the second speed.

[0069] Here, in actual application, the vehicle needs to accelerate to the second speed with a preset acceleration first, then drive at a constant speed...

Embodiment 2

[0141] In order to realize the method of the embodiment of the present invention, this embodiment provides a speed control device, such as Figure 6 As shown, the device includes:

[0142] The first determining unit 61 is configured to determine the first duration according to the first speed, the second speed and the first distance of the vehicle after the vehicle enters the preset area of ​​the intersection; the first speed is the The current driving speed; the second speed is the maximum speed limited by the road section; the first distance is the distance between the current position of the vehicle and the stop line; the first duration characterizes the vehicle at the second The time it takes for the speed to reach the stop line;

[0143] The second determining unit 62 is configured to determine a first moment by using the first duration and the second duration; the second duration is the cycle duration of the signal light; the first moment represents the period of the fi...

Abstract

The invention discloses a speed control method. The method comprises the steps that after a vehicle enters a preset area of an intersection, a first time length is determined according to the first speed, the second speed and the first distance of the vehicle; the first speed is the current driving speed of the vehicle; the second speed is the maximum speed limited by a road; the first distance isthe distance between the current position of the vehicle and a stop line; the first time length represents the length of time required for the vehicle to reach the stop line at the second speed; thefirst time length and the second time length are used to determine a first time; the second time length is the time length of the period of a signal light; the first time represents the time of the first time length in the current period of the signal light; a first parameter is determined according to the first time and a first time period; the first time period is a green light time period; thefirst parameter represents a relevant parameter for guiding the vehicle speed; and the first parameter is sent to the vehicle. The invention further discloses a speed control device and a computer storage medium.

Description

technical field [0001] The present invention relates to communication technology, in particular to a speed control method, device and computer storage medium. Background technique [0002] With the continuous increase of vehicles on the road, it is particularly important to carry out traffic control on vehicles at intersections. Data show that the ratio of traffic accidents at intersections such as three-fork intersections and four-fork intersections is very large in all traffic accidents. [0003] On the other hand, since the driver cannot know the timing information of the signal lights at the intersection ahead, he cannot timely adjust the vehicle speed according to the timing information so as to pass through the intersection more efficiently. [0004] In order to solve the above problems, a traffic light control system solution is proposed. In this scheme, how to control the speed of vehicles so that as many vehicles as possible can pass through the intersection witho...
