Abstract

The embodiment of the invention discloses a correction method and device of an intelligent driving algorithm. The method includes steps: obtaining an ideal driving scheme during driving of a test vehicle in a virtual environment including abnormal problem scenes; obtaining perception information for the virtual environment during driving of the test vehicle in the virtual environment; operating the intelligent driving algorithm according to the perception information, and obtaining a reference driving scheme; and comparing the reference driving scheme with the ideal driving scheme, and correcting a determination logic and / or an algorithm parameter of the intelligent driving algorithm according to a control quantity difference in a comparison result to enable the control quantity differencein the comparison result to be in a preset difference range. By adopting the scheme provided by the method and device, the efficiency for correcting the intelligent driving algorithm in the abnormalproblem scenes can be improved.

Description

technical field [0001] The present invention relates to the technical field of intelligent driving, in particular to a method and device for correcting an intelligent driving algorithm. Background technique [0002] In the intelligent driving system, the main technical links include the perception of the environment, driving decision-making and driving control. The sensors in the smart vehicle can collect various sensor data, and the perception algorithm can perceive obstacles and other vehicles in the sensor data. Driving is controlled. Each link needs to do a lot of road tests to improve the safety of smart vehicles when driving. [0003] During the actual road test, various road conditions may be encountered. In abnormal problem scenarios, intelligent driving algorithms cannot make reasonable and effective decisions. Such abnormal problem scenarios can also be called long-tail problem scenarios. For example, scenarios such as sprinklers, broken down vehicles, triangula...
