Anomaly detection method and device for traffic light detection module in automatic driving vehicle

Abstract

The invention provides an anomaly detection method and device for a traffic light detection module in an automatic driving vehicle; the method comprises: acquiring a driving distance between the automatic driving vehicle and a traffic light intersection in an automatic driving vehicle driving process; detecting whether the traffic light detection module is abnormal or not by combining a traffic light detection result of the traffic light detection module when the driving distance is determined to be smaller than a preset distance threshold value, so that the abnormality of the traffic light detection module in the automatic driving vehicle is detected, the abnormality can be discovered in time, and the effectiveness and safety of the automatic driving vehicle passing through the traffic light intersection are improved.

Description

technical field [0001] The present application relates to the technical field of automatic driving, and in particular to a method and device for abnormality detection of a traffic light detection module in an automatic driving vehicle. Background technique [0002] At present, in the self-driving vehicle, in order to make the self-driving vehicle pass through the traffic light intersection safely and effectively, the self-driving vehicle is equipped with a traffic light detection module, and the self-driving vehicle obtains the traffic light information of the traffic light intersection ahead through the traffic light detection module , and control the self-driving vehicle to pass through the traffic light intersection according to the traffic information. [0003] In practical applications, during the driving process of the self-driving vehicle, due to some reasons, for example, the traffic light image acquisition unit in the traffic light detection module is abnormal, or t...
