PLM-Net: Perception Latency Mitigation Network for Vision-Based Lateral Control of Autonomous Vehicles

This study introduces the Perception Latency Mitigation Network (PLM-Net), a novel deep learning approach for addressing perception latency in vision-based Autonomous Vehicle (AV) lateral control systems. Perception latency is the delay between capturing the environment through vision sensors (e.g., cameras) and applying an action (e.g., steering). This issue is understudied in both classical and neural-network-based control methods. Reducing this latency with powerful GPUs and FPGAs is possible but impractical for automotive platforms. PLM-Net comprises the Base Model (BM) and the Timed Action Prediction Model (TAPM). BM represents the original Lane Keeping Assist (LKA) system, while TAPM predicts future actions for different latency values. By integrating these models, PLM-Net mitigates perception latency. The final output is determined through linear interpolation of BM and TAPM outputs based on real-time latency. This design addresses both constant and varying latency, improving driving trajectories and steering control. Experimental results validate the efficacy of PLM-Net across various latency conditions.

NDST: Neural Driving Style Transfer for Human-Like Vision-Based Autonomous Driving

Autonomous Vehicles (AV) and Advanced Driver Assistant Systems (ADAS) prioritize safety over comfort. The intertwining factors of safety and comfort emerge as pivotal elements in ensuring the effectiveness of Autonomous Driving (AD). Users often experience discomfort when AV or ADAS drive the vehicle on their behalf. Providing a personalized human-like AD experience, tailored to match users' unique driving styles while adhering to safety prerequisites, presents a significant opportunity to boost the acceptance of AVs. This paper proposes a novel approach, Neural Driving Style Transfer (NDST), inspired by Neural Style Transfer (NST), to address this issue. NDST integrates a Personalized Block (PB) into the conventional Baseline Driving Model (BDM), allowing for the transfer of a user's unique driving style while adhering to safety parameters. The PB serves as a self-configuring system, learning and adapting to an individual's driving behavior without requiring modifications to the BDM. This approach enables the personalization of AV models, aligning the driving style more closely with user preferences while ensuring baseline safety critical actuation. Two contrasting driving styles (Style A and Style B) were used to validate the proposed NDST methodology, demonstrating its efficacy in transferring personal driving styles to the AV system. Our work highlights the potential of NDST to enhance user comfort in AVs by providing a personalized and familiar driving experience. The findings affirm the feasibility of integrating NDST into existing AV frameworks to bridge the gap between safety and individualized driving styles, promoting wider acceptance and improved user experiences.
