This paper proposes a novel method to improve the end-to-end steering prediction accuracy of autonomous vehicles. Conventionally, sensor fusion methods using expensive LiDAR and radar sensors have been mainly used, but in this paper, we propose sensor fusion using cost-effective CAN bus data. CAN bus data contains information such as vehicle speed, steering angle, and acceleration, and can improve the accuracy of computer vision models by fusion with image data. Experimental results show that models using CAN bus data reduce RMSE by 20% compared to existing models, and some models show up to 80% reduction.
