Embodiment Construction

[0065] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0066] At present, with the increase of vehicle utilization rate, due to the limitations of human perception and control ability, when thousands of vehicles share the same road at the same time, it will inevitably lead to traffic jams and traffic accidents. According to the statistics of traffic accidents, accidents caused by drivers account for about 90% of traffic accidents. Self-dr...

Abstract

The invention discloses an obstacle avoidance method and device, comprising: acquiring a first specific position of the obstacle if an obstacle is detected during the running of an automatic driving vehicle; determining the position of the obstacle and the vehicle body according to the first specific position The current distance; through the current distance, determine the four coordinate points of the area where the obstacle is located when the body safely avoids the obstacle; based on the four coordinate points, use the Bessel formula to calculate the obstacle avoidance path. Judging whether the driving road is smooth by detecting whether there is an obstacle, determining the current distance from the vehicle body according to the position of the obstacle, determining the coordinate point according to the current distance, and then calculating the obstacle avoidance path according to the coordinate point, the Bessel formula is compared with the existing technology The calculation method and amount of calculation in the algorithm are relatively small, so when an obstacle is detected, the computer can calculate the path around the obstacle in a short time to avoid traffic accidents.

Description

technical field [0001] The invention relates to the technical field of automatic driving vehicles, in particular to an obstacle avoidance method and device. Background technique [0002] At present, with the increase of vehicle utilization rate, due to the limitations of human perception and control ability, when thousands of vehicles share the same road at the same time, it will inevitably lead to traffic jams and traffic accidents. According to the statistics of traffic accidents, accidents caused by drivers account for about 90% of traffic accidents. Self-driving vehicle is a kind of intelligent mobile robot. Its research purpose is to replace human drivers in autonomous driving of vehicles, so as to improve driving safety and efficiency. With the development of artificial intelligence, pattern recognition, computer, electronics and other disciplines, autonomous vehicles have become a global research hotspot. Autonomous vehicle technology can be roughly divided into per...
