Abstract

The invention relates to a test positioning method and device for a lane departure warning (LDW) function. The method comprises the following steps: extracting CAN signal data in a camera video file;and positioning an LDW function event scene from the CAN signal data according to a preset LDW function event rule. According to the invention, the LDW function event scene is automatically positionedfrom the CAN signal data collected by the camera through the pre-designed LDW function event rule. Compared with the prior art that videos for road testing need to be visually screened, manpower andtime are consumed, subjectivity is large, and reliability cannot be guaranteed, the LDW function event can be automatically positioned, manpower and material resources are saved, and quality can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of automobile automatic driving, in particular to a method and device for testing and positioning a lane departure warning function. Background technique [0002] LDW (Lane Departure Warning, lane departure warning) is an important function in ADAS (Advanced Driving Assistant System, automatic driving assistance system). Positional relationship, judging the behavior of the vehicle departing from the lane and reminding the driver in time, so as to prevent the occurrence of lane departure accidents caused by driver negligence. Lane departure warning system is a car driving safety assistance system, which is designed to help drivers avoid or reduce lane departure accidents. [0003] In order to verify the reliability and safety of the LDW function, the lane departure warning (LDW) is one of the core functions of the automatic driving assistance system (ADAS), and the road test provided for this function is ess...
