Abstract

The invention discloses an emergency event simulation method used for driverless car training simulation. The method is realized through the following ways: firstly, carrying out analysis and classification on a typical emergency event; then, carrying out text description on the emergency event, and appointing the main body, the behavior and the object of the emergency event; then, carrying out logic expression on a behavior relationship which may be related by the emergency event; and finally, adopting a behavior tree method to simulate the emergency event so as to improve the training efficiency of the intelligent behavior of a driverless car. The emergency event simulation method which is put forward by the invention has good fidelity and universality, and a technical scheme can be provided for quickly training and evaluating the danger perception ability of the intelligent behavior of the driverless car.

Description

technical field [0001] The invention relates to a simulation method, in particular to an emergency event simulation method for unmanned vehicle training simulation, belonging to the field of unmanned driving. Background technique [0002] At present, the research on unmanned vehicles is in full swing driven by the development of artificial intelligence and the continuous update of computing power. Various traditional automakers and emerging Internet car manufacturers have announced that they will mass-produce autonomous driving at the level of L3 or above around 2020. car. In order to catch up with this rhythm, various manufacturers are stepping up various bench tests and road tests for unmanned vehicles. Since the intelligent behavior of unmanned vehicles determines its degree of automation, its research and evaluation have always been the focus of technology. Although road testing is a necessary stage for vehicle development and verification, it is unrealistic to conduct...
