Embodiment 1

[0143] In Embodiment 1, the final first traffic control instruction is generated by the automatic driving vehicle 10 (the color is highlighted in the figure).

[0144] Figure 4 It shows the first solution for controlling an automatic driving vehicle provided by the embodiment of the present invention.

[0145] Such as Figure 4 As shown, in step S401, a roadside device 20 (left side) generates a second traffic control instruction 41 for the autonomous vehicle 10 (left side in the figure). Wherein, the roadside device 20 can generate the second traffic control instruction 41 according to the traffic condition information collected by its own sensor, or can also generate the second traffic control instruction 41 based on the traffic condition information collected by its own sensor and other roadside devices 20 in the traffic system 100. The traffic control information is used to generate the second traffic control command 41 .

[0146] In step S402, the roadside device 20 s...

Embodiment 2

[0153] In the second embodiment, the final first traffic control instruction is generated by the automatic driving vehicle 10 (the color is highlighted in the figure).

[0154] Figure 5 The second scheme for controlling an automatic driving vehicle provided by the embodiment of the present invention is shown.

[0155] Such as Figure 5 As shown, in step S501, a roadside device 20 (left side) collects traffic situation information near the self-driving vehicle 10 (left side) through its own sensor and / or from other roadside devices 20 (right side, in the figure) Only one is shown, in fact, the traffic situation information near the self-driving vehicle 10 can be obtained from multiple other roadside devices 20 (traffic situation information) as the second traffic control information 51 .

[0156] In step S502, the roadside device 20 sends the second traffic control information 51 to the autonomous vehicle 10 (left side).

[0157] In step S503 , the autonomous vehicle 10 (on...

Embodiment 3

[0162] In the third embodiment, the final first traffic control instruction is generated by the roadside device 20 (the color is highlighted in the figure).

[0163] Figure 6 It shows a third solution for controlling an automatic driving vehicle provided by an embodiment of the present invention.

[0164] Such as Figure 6 As shown, in step S601, a roadside device 20 (left side) collects traffic situation information near the self-driving vehicle 10 (left side) through its own sensor and / or from other roadside devices 20 (right side, in the figure) Only one is shown, in fact, the traffic situation information near the self-driving vehicle 10 can be obtained from multiple other roadside devices 20 (traffic situation information) as the second traffic control information 61 .

[0165] In step S602, the self-driving vehicle 10 (on the left side) collects information 63 through its own sensors and / or receives information 62 from other self-driving vehicles 10 as first traffic c...

Abstract

The invention relates to the technical field of traffic, in particular to a vehicle control method and equipment used for enhancing the efficiency of the whole traffic system, effectively preventing traffic accidents and reducing traffic jams. According to the vehicle control method provided by the embodiment of the invention, first equipment obtains first traffic control information and second traffic control information; the first traffic control information is collected by an autonomous vehicle; the second traffic control information is centralized control information; and the first equipment generates a first traffic control instruction according to the first traffic control information and the second traffic control information and is used for controlling the autonomous vehicle to run. The centralized control and vehicle autonomous control are combined to control the running of the autonomous vehicle; a local traffic situation of a traffic system is considered, the integral traffic situation in the traffic system is also considered; and therefore, the flow and efficiency of the whole traffic system can be enhanced, and the probability of occurrence of traffic accidents can bereduced.

Description

technical field [0001] The present invention relates to the technical field of traffic, in particular to calling a vehicle control method, device and system. Background technique [0002] Self-driving vehicles (Autonomous vehicles, or Self-piloting automobile), also known as unmanned vehicles, computer-driven vehicles, or wheeled mobile robots, are vehicles that use computer technology to achieve unmanned driving. Self-driving vehicles rely on artificial intelligence, visual computing, radar, monitoring devices and positioning systems to work together, so that the computer can automatically and safely control the driving of the vehicle without any active human operation. [0003] In the future traffic system, there will be a large number of self-driving vehicles. How to control these self-driving vehicles so that they can drive safely is an urgent problem to be solved. Current traffic control methods (such as traffic light signal control) and traffic command systems are usu...
