Problems solved by technology

That is to let the vehicle perceive the surrounding environment and road conditions like a human, plan the driving route, make relevant analysis judgments and decisions, and complete a series of operations such as refueling, braking, steering, etc. This solution has high requirements for the vehicle terminal. Moreover, the vehicle-mounted terminal can only perform predictions within a short distance, and cannot realize global automatic driving, and the safety cannot be guaranteed.

Embodiment 1

[0035] This embodiment discloses a centrally controlled automatic driving method, which includes a step of implementing a 3D dynamic model of the city and a step of controlling automatic driving, and the two steps are parallel. The step of realizing the city 3D dynamic model is mainly to maintain the city 3D dynamic model, and the step of automatic driving control is to realize the automatic driving control. The two steps are described in detail below.

[0036] 1) Realization steps of urban 3D dynamic model, refer to figure 2 , specifically including the following steps S201 and S202:

[0037] S201: Each regional subsystem acquires monitoring data in real time through multiple dimensions of monitoring equipment in the area, and identifies various dynamic objects and static objects in the space according to the monitoring data uploaded by the monitoring equipment in real time, and constructs a system based on the recognition results. And update the 3D dynamic model of the ar...

Embodiment 2

[0059] This embodiment discloses a vehicle-mounted terminal, including a processor and a memory, the memory stores a computer program, and the computer program implements the following steps when executed by the processor:

[0060] Receive the city 3D dynamic model including static objects and dynamic objects pushed by the central control system;

[0061] According to the 3D dynamic model of the city and its own location information, as well as the video information collected by its own vehicle camera, it predicts the situation of static objects and dynamic objects within a preset distance, and performs automatic driving according to the prediction results.

[0062] For more content, please refer to the content of the vehicle-mounted terminal part of the embodiment, which will not be repeated here.

Embodiment 3

[0064] This embodiment discloses a global automatic driving system, including:

[0065] Such as the vehicle-mounted terminal of Embodiment 2;

[0066] Multiple regional subsystems, each regional subsystem is used to obtain monitoring data in real time through multiple dimensions of monitoring equipment in the area, and identify various dynamic objects and static objects in the space according to the monitoring data uploaded by the monitoring equipment in real time , and construct and update the regional 3D dynamic model including static objects and dynamic objects according to the recognition results;

[0067] A central control system, the plurality of regional subsystems are respectively connected to the central control system, and the central control system is used to obtain the regional 3D dynamic models of each region from each regional subsystem and integrate them to obtain the urban 3D dynamic model of the entire city , and push the 3D dynamic model of the city to each ...

Abstract

The invention discloses a global automatic driving method and system and a vehicle-mounted terminal. The method comprises the steps that: a vehicle-mounted terminal uploads video information collectedby the vehicle-mounted terminal to a central control system to serve as a part of an urban 3D dynamic model which is maintained by the central control system and comprises static objects and dynamicobjects, and receives the urban 3D dynamic model pushed by the central control system; and the vehicle-mounted terminal predicts the conditions of a static object and a dynamic object in a preset distance according to the urban 3D dynamic model, the position information of the vehicle-mounted terminal and video information collected by a vehicle-mounted camera of the vehicle-mounted terminal, andperforms automatic driving according to a prediction result. According to the Global automatic driving method and system and the vehicle-mounted terminal of the invention, the calculation burden of the vehicle-mounted terminal can be reduced, global automatic driving control can be achieved, and safety can be fully guaranteed.

Description

technical field [0001] The present invention relates to the traffic field, in particular to a global automatic driving method, system and vehicle-mounted terminal. Background technique [0002] Autonomous driving technology is a current research hotspot. Autonomous driving relies on artificial intelligence, which allows computers to operate a motor vehicle automatically and safely without a human being actively operating it. Autonomous driving can not only liberate people from laborious driving operations, but also can greatly improve the safety of motor vehicles and reduce traffic accidents because the accuracy, response speed and repeatability of computers far exceed those of humans. [0003] The current autonomous driving technology is mainly controlled by the vehicle terminal, which simulates all human behaviors when driving a motor vehicle. That is to let the vehicle perceive the surrounding environment and road conditions like a human, plan the driving route, make re...
