Problems solved by technology

However, in some scenarios, such as high-speed scenarios, because the scenario is relatively simple, the control algorithm still performs a large number of calculations in real time, which obviously has the problem of wasting computer resource performance.

Embodiment Construction

[0021] In order to facilitate those skilled in the art to understand the technical solution of the present invention, the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0022] like figure 1 As shown, the technical solution of the present invention is an autonomous car following control method for an unmanned electric vehicle, which mainly includes a driving scene recognition module, a strategy conversion control module, and a monitoring and forced exit control module.

[0023] Among them, the driving scene identification module is mainly used to identify and confirm the driving scene to which the current driving belongs. Generally, driving scenes are divided into: high-speed scenes, urban scenes, and suburban scenes. Urban scenes and suburban scenes are not suitable for following vehicles due to heavy traffic flow, many pedestrians, many obstacles, frequent and complicated changes in road conditions, and ...

Abstract

The invention discloses an autonomous vehicle following control method of an unmanned electric vehicle. A global road network file and GPS positioning information data are mainly used for analysis, vehicle driving scene identification and distinguishing are realized, the control strategy is switched and implemented based on the control technology, the characteristics of the millimeter wave radar and the front camera are utilized, the driving state and the lane line condition of the front vehicle are monitored in real time, the requirements for safety and comfort of passengers are considered bycombining the self state, cruise control over the vehicle is achieved in the mode of following the front vehicle, and automatic driving control over part of scenes is achieved in the mode of following the front vehicle.

Description

technical field [0001] The invention belongs to the field of unmanned driving of automobiles, and more specifically relates to an autonomous follow-up control method of an unmanned electric vehicle. Background technique [0002] At present, with the breakthrough of unmanned vehicle technology and the decrease in the cost of perception system components year by year, the unmanned vehicle technology has become a hot topic in today's automotive technology research. In mainstream research, there are two main problems, one is the trade-off between sensor performance and cost, and the other is the trade-off between decision-making control performance and real-time performance. Some experts and scholars proposed to use the combined configuration and algorithm design of millimeter-wave radar to replace the performance of laser radar. In comparison, the cost of millimeter-wave radar is much lower than that of laser radar, and the detection distance of long-wave millimeter-wave radar ...
