Special Issue Information

Dear Colleagues,

Intelligent vehicles have been considered an essential way to improve urban mobility and reduce emission pollution and traffic accidents. With the development of artificial intelligence, such as deep learning, intelligent vehicle technologies have obtained enormous success. However, due to the unmature of critical technologies, such as environment perception, motion planning, behavior decision, and motion control, the intelligent vehicle still cannot be deployed to real and complex scenarios.

The intelligent vehicle is a very complicated technical system. Critical technologies from different disciplines, such as sensor technology, pattern recognition, control engineering, artificial intelligence, and vehicle engineering, can affect its performance. This Special Issue explores the recent progress in these related research fields. Welcome topics include, but are not strictly limited to the following:

  • Imaging and sensor technology, such as LiDAR, camera, millimeter wave radar, and so on;
  • Environment perception technology, such as vehicle/pedestrian detection, tracking and prediction, travelable area detection, ground segmentation, and so on;
  • Planning and control technology, such as global planning, local planning, behavior decision, motion control, and so on;
  • Navigation and localization technology, such as lidar odometry, vision odometry, simultaneous localization and mapping (SLAM), and so on;
  • Intelligence test and evaluation.

To minimize the occurrence of traffic accidents, such as vehicle rear-end collisions, while enhancing vehicle following, stability, economy, and ride comfort, a hierarchical adaptive cruise control strategy for vehicles is proposed. The upper-level controller computes the desired vehicle output acceleration based on model predictive control and switches between speed and spacing control in accordance with driving conditions. The brake/throttle opening switching model, brake control inverse model, and throttle opening inverse model in the lower-level controller of ACC are designed to obtain the desired throttle opening and braking pressure of the vehicle, thereby achieving control of the vehicle. A joint simulation platform was established using PreScan, CarSim and Matlab/Simulink. Finally, simulations for three typical working conditions were conducted in Simulink to verify the performance of the adaptive cruise control strategy. The results indicate that, in both the constant-speed cruise and vehicle-following cruise conditions, the vehicle can rapidly and stably follow the set initial speed and consistently maintain a safe distance from the preceding vehicle. Under the emergency braking condition, the vehicle can promptly respond with deceleration, ensuring driving safety. The proposed control strategy can accurately and safely track the target vehicle in diverse driving conditions and can concurrently fulfill the requirements of economy and comfort during vehicle travel.

To address the challenges of limited detection precision and insufficient segmentation of small to medium-sized objects in dynamic and complex scenarios, such as the dense intermingling of pedestrians, vehicles, and various obstacles in urban environments, we propose an enhanced methodology. Firstly, we integrated a point cloud processing module utilizing the DBSCAN clustering algorithm to effectively segment and extract critical features from the point cloud data. Secondly, we introduced a fusion attention mechanism that significantly improves the network’s capability to capture both global and local features, thereby enhancing object detection performance in complex environments. Finally, we incorporated a CSPNet downsampling module, which substantially boosts the network’s overall performance and processing speed while reducing computational costs through advanced feature map segmentation and fusion techniques. The proposed method was evaluated using the KITTI dataset. Under moderate difficulty, the BEV mAP for detecting cars, pedestrians, and cyclists achieved 87.74%, 55.07%, and 67.78%, reflecting improvements of 1.64%, 5.84%, and 5.53% over PointPillars. For 3D mAP, the detection accuracy for cars, pedestrians, and cyclists reached 77.90%, 49.22%, and 62.10%, with improvements of 2.91%, 5.69%, and 3.03% compared to PointPillars. Full article
