Detection method and device for transverse control function of vehicle ADAS system and storage medium

Abstract

The invention discloses a method and device for detecting the transverse control function of a vehicle ADAS system and a storage medium, and the method comprises the steps: obtaining the actual diameter of a wheel, and obtaining the transverse operation data of a vehicle in real time; the transverse operation data at least comprise wheel image diameters acquired by an image acquisition device arranged at the side part of the vehicle and image distances between the side part of the vehicle and corresponding lane lines; according to a preset proportion coefficient, the actual wheel diameter, the wheel image diameter and the image distance, the actual distance between the side portion of the vehicle and the corresponding lane line is calculated, and the proportion coefficient reflects the proportion relation between the image distance and the actual distance; and processing the actual distance, and detecting a transverse control function associated with the actual distance according to a processing result. According to the detection method and device for the transverse control function of the vehicle ADAS and the storage medium provided by the embodiment of the invention, the redundancy of data processing is reduced, and the accuracy of performance detection and analysis of the transverse control function of the vehicle is ensured.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a detection method, equipment and storage medium for the lateral control function of a vehicle ADAS system. Background technique [0002] Vehicles controlled by ADAS (Advanced Driver Assistance System) have great advantages in improving driving safety and reducing traffic accidents, and are the main focus of research on vehicle technology development today. [0003] Lateral control refers to path tracking, that is, the vehicle is always driven along the desired path through automatic steering control. In order to ensure the safety of the vehicle and the comfort of the ride, today's vehicles pass the LCC (vehicle centering) / LDW in ADAS (Lane Departure Warning) / LKA (Lane Keeping) and other functions control the vehicle laterally. Among them, the performance detection (such as false alarm rate and false alarm rate) of the vehicle lateral control function depends on the relations...

[0003] Lateral control refers to path tracking, that is, the vehicle is always driven along the desired path through automatic steering control. In order to ensure the safety of the vehicle and the comfort of the ride, today's vehicles pass the LCC (vehicle centering) / LDW in ADAS (Lane Departure Warning) / LKA (Lane Keeping) and other functions control the vehicle laterally. Among them, the performance detection (such as false alarm rate and false alarm rate) of the vehicle lateral control function depends on the relationship between the left and right sides of the vehicle and the corresponding left and right sides. The distance data between two lanes, and the calculation of this distance data, in the prior art, is obtained through complex calculations from the vehicle offset angle and related curvature data, which will increase the redundancy of data processing and extend the The time of the distance calculation process between the vehicle and the corresponding lane line makes it impossible to obtain accurate real-time distance data in time, which in turn affects the performance detection of the vehicle's lateral control function
