ACDR: Autonomous-Car Drive Recorder

Abstract

Herein, a drive recorder system for autonomous cars that can be used to analyze accidents that occur during autonomous driving is proposed. In many field operational tests of autonomous cars, vehicle speed, steering angle, and camera data are recorded in the log file. Only relying on these log files without simultaneously monitoring the operator or driver’s actions results in much information being lost that can be used for accident investigation. To solve this problem, an autonomous-car drive recorder that can respond appropriately when accidents occur and minimize the possibility of accidents is proposed. In the system, during an accident, the environment detected around the vehicle and the actions of the driver and operator are recorded, and the data are used to troubleshoot the accident occurrence.
