Path-tracking control, however, suffers from the uncertainties in the steering system, vehicle motion dynamics, and road-tire frictions, etc. In this paper, an extended state observer (ESO) based linear quadratic regulator (LQR) is proposed for the path-tracking of self-driving buses. In a departure from conventional LQR design, the bus motion dynamic is treated as a simple canonical model, the discrepancy of which from the real bus, caused by the nonlinearities and uncertainties, is lumped as a total disturbance state to be estimated by ESO online. With the total disturbance mitigated in the feedback loop in real-time, the bus motion dynamic is enforced to behave as the canonical model to be easily controlled by LQR. Experimental results show that relative to conventional LQR, the ESO-LQR design can enhance the transient response by 21%, and reduce the path-tracking error by up to 72 % in the presence of steering wheel angle offset.","PeriodicalId":419836,"journal":{"name":"2021 5th CAA International Conference on Vehicular Control and Intelligence (CVCI)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123052228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a traditional visual SLAM system, this is usually done by extracting and matching image features. The accuracy of the loop closure detection and the precision of the pose-constraint provided by loop closing is the bottleneck restricting the loop closing accuracy. Since image features is sensitive to large viewpoint changes, in this paper, we propose a novel neural network architecture VPD-Map, which takes visual pointcloud to provide a global 3D visual descriptor for fast loop closure detection and a top-view feature map for pose-constraint prior. Since the descriptor and feature map are based solely on visual pointcloud information, it is robust to viewpoint changes. VPD-Map can also serve as the backend of a visualSLAM system. Experiment on loop closure detection shows that this descriptor can perform viewpoint-free loop closure detection and outperforms traditional loop detection algorithms like bag-of-word model on the KITTI Odometry Dataset.","PeriodicalId":419836,"journal":{"name":"2021 5th CAA International Conference on Vehicular Control and Intelligence (CVCI)","volume":"03 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127206069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aiming at the cooperative merging control at highway ramp, we present a vehicle cooperative control algorithm for distributed consensus considering communication delay among vehicles. First, we propose a group-based strategy and design a cost function to obtain the optimal vehicle passage order containing total travel time and delay. Then we model the merging vehicles formation as a multi-agent system and combine it with the multi-agent consensus theory to achieve the desired vehicle space and speed. Finally, based on the Webots simulation software and numerical analysis, we compare the traditional traffic signal control, Hamilton optimal control and the proposed method in terms of speed, position, arrival time and driving risk.

In this paper, we establish a new landmark dataset and put forward an auxiliary localization method based on landmark detection to improve the position accuracy, where a multi-task learning model is applied for both keypoint prediction and bounding box regression. We further propose the Keypoint Recovery Module (KRM) as a model-agnostic plug-in, to mitigate the challenge of missing rate. By this, the proposed approach is trained and validated on our proposed landmark dataset. Comparative experimental results show that the multi-task architecture in conjunction with KRM greatly enhances the accuracy of landmark detection, surpassing traditional methods.","PeriodicalId":419836,"journal":{"name":"2021 5th CAA International Conference on Vehicular Control and Intelligence (CVCI)","volume":"224 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122522325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But traditional fault diagnosis methods can’t ensure the safety of the batteries, since they are week in the detection of early minor battery fault. Therefore, a high-precision and low-cost battery diagnosis method is proposed. This method is based on the fusion of three individual sub-methods, that is modified correlation coefficient method, sample entropy and modified threshold method. The three sub-methods above are sensitive to different types of faults. By integrating their diagnosis result, the fusion method has a strong fault diagnosis ability for all types of faults. Meanwhile, it can largely shorten the early warning time of major faults. Result of experiments verifies that the method proposed does well in early minor fault diagnosis and can detect the fault at least 5 minutes in advance.","PeriodicalId":419836,"journal":{"name":"2021 5th CAA International Conference on Vehicular Control and Intelligence (CVCI)","volume":"333 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122846617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

LabVIEW software is used to design a feedforward fuzzy PID (Proportional Integral Derivative) controller for new automatic pressure regulating valve, the test bench based on the response characteristics of which is constructed using a NI data acquisition card, sensors, and automatic pressure regulating valve, etc. The pressure response characteristics of automatic pressure regulating valve under the three control algorithms, namely PID control, feedforward PID control and feedforward fuzzy PID control， are verified by experiments. The experimental results under different algorithms are compared with relevant standards， and the results show that the feedforward fuzzy PID control algorithm provides the best pressure response characteristics of automatic pressure regulating valve with a shorter response time, a smaller overshoot and a better stability.

The author supposes that solutions to solve traffic congestion are traffic flow diverted in a range and drivers having enough time to change lanes smoothly. In order to verify the impact of ICS on traffic flow, the author utilizes PTV-VISSIM and Python as secondary traffic dynamic planning to compare total delay time and average travel time in a fixed route whether there is dynamic guidance. In the end, it is concluded that ICS greatly improve the congestion condition. Drivers’ lane-changing behavior is also influenced by the setting of ICS, so that the author utilizes CarSim, and Simulink software setting horizontal and longitudinal control strategies to build the driver’s lane-changing model.
