Problems solved by technology

However, vehicle-to-vehicle communication and V2X technology cannot achieve global perception and coordinated scheduling of the driving intentions of all vehicles within a certain area. The driving intention of the vehicle, and then guide the vehicle's driving decision-making according to the order of the driving intention of each vehicle after collaborative dispatching, so that the vehicle can drive safely in sequence, and improve the safety and traffic efficiency of intelligent driving in the mode of human-vehicle co-driving

Embodiment 1

[0066] This embodiment discloses an intelligent vehicle-oriented area cooperative driving intention scheduling method. This method is used in the intelligent driving of the human-vehicle shared driving mode, which can avoid the risk of vehicle conflict and improve driving safety. On the other hand, it will also improve the area The overall traffic efficiency within the range, the specific process of the method is as follows figure 1 shown, including:

[0067] S1. Acquiring state information and location information of the vehicle; at the same time, obtaining driving intention information of the vehicle identified by the state information of the vehicle. In this embodiment, the acquired vehicle state information specifically includes the state of the accelerator pedal of the vehicle, the steering wheel angle, the state of the brake pedal, and the absolute speed of the vehicle.

[0068] Wherein, the process of identifying the driving intention information of the vehicle through...

Embodiment 2

[0092] This embodiment discloses an intelligent vehicle-oriented area cooperative driving intention scheduling device, such as Figure 4 As shown, it includes information acquisition module, driving intention global map generation module, map model construction module and global dispatch result generation module: the functions realized by each module are as follows:

[0093] An information acquisition module, configured to acquire status information and location information of the vehicle, and to acquire the driving intention of the vehicle identified through the status information and location information of the vehicle;

[0094] The driving intention global map generation module is used to generate the driving intention global map of all vehicles in the dispatching area according to the driving intention information, vehicle status information and vehicle position information of the vehicles in the dispatching area;

[0095] A map model building module, used to build a grid ...

Embodiment 3

[0099] This embodiment discloses an intelligent vehicle-oriented regional cooperative driving intention scheduling system. Based on the system of this embodiment, the intelligent vehicle-oriented regional cooperative driving intention scheduling method described in Embodiment 1 can be implemented. Such as Figure 5 As shown in , the regional coordinated driving intention scheduling system for smart vehicles in this embodiment includes a cloud scheduling system 30 , and a vehicle driving intention perception system 10 and a vehicle driving intention control system 20 installed on the vehicle. in:

[0100] The on-vehicle driving intention perception system is connected to the on-vehicle driving intention control system to obtain the state information and location information of the vehicle, and send the obtained vehicle state information and location information to the on-vehicle driving intention control system;

[0101] In this embodiment, the vehicle-mounted driving intentio...

Abstract

The invention discloses an intelligent vehicle-oriented regional cooperative driving intention scheduling method and system, and a medium, and the method comprises the steps: firstly obtaining the state information, position information and driving intention information of all vehicles in a scheduling region range, and generating a driving intention global graph of all vehicles in the scheduling region range based on the information; then constructing a scheduling area occupation grid map model; according to the scheduling area occupation grid map model, generating a global scheduling result of the vehicle driving intention of the scheduling area in cooperation with the global driving intention of the vehicle in the scheduling area range; therefore, instructing the driving decision of thevehicle in the scheduling area range through the global scheduling result of the vehicle driving intention in the scheduling area. According to the invention, the driving intention of each vehicle inthe scheduling area range can be comprehensively scheduled and controlled, the global scheduling result is generated, the vehicle driving decision is guided, on one hand, the vehicle conflict risk isavoided, the driving safety is improved, and on the other hand, the overall passing efficiency in the area range is also improved.

Description

technical field [0001] The invention relates to the field of intelligent vehicle control, in particular to a method, system and medium for intelligent vehicle-oriented regional cooperative driving intention scheduling. Background technique [0002] The development of intelligent driving will help improve the level of intelligent road traffic and promote the transformation and upgrading of the transportation industry. Before unmanned driving is completely safe and available, intelligent driving in the mode of human-vehicle sharing is the mainstream mode of intelligent transportation. In this mode, the control right of the vehicle can be transferred between the human and the vehicle, and the driver can take over the control of the vehicle and issue vehicle control instructions at any time. [0003] When the intelligent vehicle drives autonomously, the intelligent vehicle collects and recognizes environmental information in real time through the sensing device, and then makes ...
