Abstract

The invention relates to a method and a system for constructing an automatic driving experience database. The method comprises the following steps: acquiring vehicle driving data of different vehicles under different time periods, different places and different environment conditions; analyzing the vehicle driving data, extracting abnormal driving data and determining a driving difficulty scene; for each driving difficulty scene, analyzing factors causing driving difficulty in the scene, and extracting normal driving data corresponding to the abnormal driving data from the vehicle driving data one by one according to the factors; describing normal driving data corresponding to a driving difficulty scene by a structured language so as to generate automatic driving experience data, and creating an automatic driving experience database. The driving experience data obtained by analyzing the vehicle driving data can effectively improve the safety, the efficiency and the comfort during manual driving and automatic driving, and the driving range of automatic driving is expanded.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a method and system for constructing an automatic driving experience database. Background technique [0002] During the driving process, due to irregular road design, unreasonable, and deteriorating conditions, it is easy to produce blind spots, sudden braking, sudden steering, bumps, slippage, low traffic efficiency, and poor driving experience. [0003] If it is a vehicle equipped with an automatic driving assistance function, when passing through these places, it is likely to be forced to interrupt the automatic driving function due to incorrect sensor recognition or beyond the scope of automatic driving processing. [0004] We call the above-mentioned places where human driving is difficult, prone to danger, poor comfort, time-consuming, and automatic driving functions are interrupted as "difficult driving places". [0005] In order to enable self-driving vehicles ...
