Problems solved by technology

[0003] At present, there are few research methods on the reliability of self-driving cars at home and abroad, and the research is generally carried out from the perspective of the reliability of the hardware and software of self-driving cars. This method has a certain guiding effect on the reliability of self-driving cars. It has certain reference value, but in the actual driving process of self-driving cars, the traditional software and hardware reliability evaluation methods lack the consideration of the actual situation, and cannot completely analyze the reliability of self-driving cars

Abstract

The invention discloses an automatic driving automobile driving behavior reliability index evaluation method, and the method comprises the following steps: planning an automatic driving automobile driving path according to an automatic driving function testing rule of an automatic driving automobile; according to unreliable driving behaviors generated in the driving process of the automatic driving automobile, obtaining driving behavior data of the automatic driving automobile from a starting point to a terminal point in the driving path of the automatic driving automobile; calculating a reliability index value according to the driving behavior data, wherein the reliability index value comprises a first-level index and a second-level index; and calculating the reliability of the driving behavior of the autonomous vehicle according to the calculated reliability index value and a preset corresponding weight. According to the method, the reliability of software and hardware of the automatic driving automobile does not need to be analyzed, the reliability evaluation result of the automatic driving automobile can be obtained only by calculating and analyzing the driving behavior data ofthe automatic driving automobile, the reliability analysis efficiency of the automatic driving automobile is improved, and the reliability of the whole automatic driving automobile is guided and improved.

Description

technical field [0001] The present invention relates to the technical field of evaluating reliability indexes of autonomous vehicles, and more specifically, to a method for evaluating reliability indexes of driving behaviors of autonomous vehicles. Background technique [0002] With the rapid development and application of artificial intelligence technology, self-driving cars have become the main trend of the development of the modern automobile industry. A self-driving car is a mobile machine that relies on an intelligent computer system to independently complete driving tasks. It can replace human drivers in the transportation of personnel and goods, effectively reducing the occurrence of traffic accidents. However, as far as the self-driving technology currently being studied is concerned, its reliability still needs to be improved, which also seriously hinders the pace of large-scale commercial use of self-driving cars. From the development of autopilot technology to th...
