A method and system for steering and driving assistance of heavy trucks based on panoramic images

Abstract

The invention discloses a method and system for assisting steering and driving of heavy trucks based on panoramic images. The relationship between the steering wheel angle of the tractor and the declination angle of the trailer axle is used to calculate α. c Corresponding normal shaft declination angle β α , and then judge β α with beta c are equal, if β α ≠β c , and then judge β α Is it less than β c , if β α less than beta c If it is established, the driver is reminded that the vehicle slides to the inside of the turn, and returns to step S2; if β α less than beta c If it is not established, the flashing vehicle on the screen slides to the outside of the turn, and returns to step S2; if β α =β c , it means that the heavy truck turns normally, and obtains the real-time panoramic bird's-eye view to display the real-time bird's-eye image with the prediction line. The method and system can facilitate the driver to judge in advance whether accidents such as scratches and collisions will occur, so as to adjust the forward path or stop operations in time.

Description

technical field [0001] The invention belongs to the field of assisted driving of vehicles, and in particular relates to a method and system for assisting steering and driving of heavy trucks based on panoramic images. Background technique [0002] With the development of automobiles and the improvement of people's living standards, factors such as complex vehicle conditions, road congestion, and visual blind spots in vehicles have seriously affected traffic safety. Through the panoramic image, the driver can check the surrounding situation of the vehicle, which greatly reduces the visual blind spot, makes it easier for the driver to avoid obstacles such as vehicles and pedestrians, and improves the driving safety. [0003] At present, panoramic images have been widely used in small vehicles, but they are rarely used in large vehicles, especially heavy trucks. But in fact, compared with small vehicles, the visual blind spot of heavy trucks is larger, and panoramic images sho...

AI Technical Summary

Problems solved by technology

The driver controls the turning of the car through experience, resulting in a difference between the driving path of the car and the expected path, especially for heavy trucks, it is more difficult for the driver to accurately control the path of the trailer, and accidents such as scratches, collisions, and rollovers are prone to occur when turning
