Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.
[0022] Such as figure 1 As shown, an intelligent vehicle converging system under heavy traffic flow includes a roadside control unit, an information collection unit and an on-board control unit. The roadside control unit is set between the main road and the ramp ( figure 2 ); the information collection unit includes a millimeter-wave radar and a CCD camera. The millimeter-wave radar is set on the main road vehicle and the ramp vehicle to measure the position and speed of the vehicle and send it to the roadside control unit; the CCD camera is set on the main road and the ramp vehicle. Between the ramps, it is used to obtain the images of the merging vehicles on the main road and the ramp respectively, and send them to the roadside control unit, and obtain the number of me...

The invention provides a method and system for converging intelligent vehicles under heavy traffic flow, and belongs to the technical field of automatic driving vehicle decision-making systems. The roadside control unit of the present invention acquires the position and speed of the vehicle, the number of converging vehicles on the main road and the ramp, and the driving mode of each converging vehicle, respectively representing the vehicle converging efficiency η and the fuel consumption Q of the vehicle when converging 总 And the driver comfort evaluation index C, and the comprehensive evaluation index S, determine the number of road right switching m when the comprehensive evaluation index S is maximum, and control the main road vehicles and ramp vehicles according to the convergence. The present invention reduces the number of right-of-way switches of the lanes at the time of merging, greatly improves the passing efficiency of vehicles at the merging point, not only reduces the fatigue of driving operation, but also reduces the fuel consumption of vehicles, and at the same time meets the requirements of comfort and economy .
Description
technical field [0001] The invention belongs to the technical field of automatic driving vehicle decision-making systems, and in particular relates to a method and system for converging intelligent vehicles under heavy traffic flow. Background technique [0002] With the rapid development of the automobile industry and the Internet industry, smart cars have emerged as the times require, and driverless technology has also emerged. People have put forward new requirements for cars, namely "electrification, networking, intelligence, and sharing." A large number of university researchers and enterprises at home and abroad are investing in the research of unmanned driving technology, and the convergence of smart cars has always been a difficult point in this research field. [0003] When vehicles merge, the traffic conditions often encountered are more complicated, and there are many uncontrollable factors, which is why it becomes a technical difficulty. For example, the drivin...
