This paper proposes a method to identify vehicle target recognition with lidar point cloud data and machine learning; This method first establishes an ROI (region of interest), and uses voxel grid filter to downsample the lidar point cloud data in this area to reduce the amount of processed data, then use RANSAC (random sampling consensus) to remove ground points that are useless for the recognition process, and then use Euclidean clustering for clustering. A rough classifier is set to initially eliminate obstacles that cannot be vehicles, then the features of each cluster is extracted. SVM (Support Vector Machine) is used as an accurate classifier, the parameters of SVM is optimized through cross-validation and grid search to achieve the best classification effect. Finally, the optimized SVM is used to identify each cluster. Experiments show that this method can effectively detect the target vehicle in the ROI and has a good recognition accuracy.","PeriodicalId":119721,"journal":{"name":"2020 4th CAA International Conference on Vehicular Control and Intelligence (CVCI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124199379","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}

Most existing lane changing models are rule-based lane changing models which only assume one-direction impact of surrounding vehicles on the lane-changing vehicle. In fact, lane change is a process of mutual interaction between vehicles due to the complexity and uncertainty of the traffic environment. In this paper, we proposed a multi-vehicle cooperative control approach with a distributed control structure to control model. The innovation of this paper lies in that we proposed a multivehicle cooperative lane changing controller which combines game theory and model predictive control (MPC) based on vehicle to vehicle (V2V) communication; Moreover, we designed a multi-lane vehicle ordering method, and decided the optimal time and acceleration of lane change by considering the mutual interaction between vehicles. Typical scenarios were tested to verify that a lane changing vehicle could interact with other vehicles and change lanes without collision. We verified this approach of lane changing through CarSim and MATLAB cosimulation, and compared it with the conventional rule-based lane change decision controller. Test results show that the controller is capable of changing lanes in a smarter manner and guaranteeing the safety and efficiency of the autonomous vehicle.","PeriodicalId":119721,"journal":{"name":"2020 4th CAA International Conference on Vehicular Control and Intelligence (CVCI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126216155","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}

Here, a predictive compensation-based handling stability control system (PCHSCS) is developed. The PCHSCS includes three parts: a steering controller, a speed controller, and a predictor. The steering controller is adopted to control the course for resisting the lateral acceleration caused by the crosswind. The speed controller is utilized to maintain the vehicle speed, decreasing the undesired longitudinal acceleration. The predictor is applied to predict the control error and the coupling interference. The predicted information, as compensation, is combined and fed to the speed controller and the steering controller. Simulation proves the PCHSCS can improve the vehicle handling stability under strong transient crosswind conditions.","PeriodicalId":119721,"journal":{"name":"2020 4th CAA International Conference on Vehicular Control and Intelligence (CVCI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129799402","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}

Our concept is to develop a wearable assistive device that can provide motion-based assistance like the existing passive devices in the down phase of lifting, but in the up phase, can supply more load-based power. To achieve this goal, we designed two purely mechanical control mechanisms that can preload the load-based assist force and release it when the wearer intends to erect the trunk. This paper presents mathematical proof using a linked segment model and moment balance equations in the sagittal plane. Simulation proof is also provided based on a simple musculoskeletal model which executed sagittal plane lifting with a 20kg load in hands in stoop posture under three different conditions (no assist, classic mode, enhanced mode). The subsequent results suggest that the device substantially reduces the muscle force and lumbar moment by 27.7-43.5%, and in the enhanced mode, the efficacy is better than the classic mode. No such a quasi-passive back-support exoskeleton was found at the time of writing. This design concept is promising to help reduce the risk of back injuries in heavy load lifting and works that need workers to keep a forward bending and static holding postures such as vehicle assembly.","PeriodicalId":119721,"journal":{"name":"2020 4th CAA International Conference on Vehicular Control and Intelligence (CVCI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121663295","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 order to achieve good tracking performance and anti-disturbance ability, a robust command-filtered backstepping control strategy of the SP-NPCR is proposed in this paper. Firstly, based on the SP-NPCR model in dq frame, the command-filtered backstepping controller is constructed, which compose of the output voltage controller and the reactive current controller. The command filter is used to meet the requirement of analytic differentiation of the virtual controller and simplify the controller structure. Then, the global stabilization of the SP-NPCR is conducted and proved by the Lyapunov stability theory. The simulation for SP-NPCR has been carried out to demonstrate that the proposed system has better dynamic property and robustness compared with the conventional proportional- Integral method.","PeriodicalId":119721,"journal":{"name":"2020 4th CAA International Conference on Vehicular Control and Intelligence (CVCI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130692647","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}

To be specific, the communication topology of bidirectional leader-follower is used to describe the vehicles' communication connection in the vehicle- vehicle/vehicle- to-infrastructure (V2X) environment. Then, a nonlinear state feedback control algorithm for follower vehicles is put forward through merging the phenomenon of car-following interactions, the spacing error, velocity difference and angular difference in relation to the leader vehicle. The proposed algorithm's stability is verified by means of Lyapunov technique. And then, simulation experiments under two scenarios: the leader vehicle runs on the straight road and curved road, respectively, and the followers run after the leader vehicle.

The envelope control based on the sideslip angle and yaw rate phase plane can effectively restrict the vehicle states in the safe operation region for ensuring the stability of the vehicle. However, In most of such control schemes, many stable regions are not included in the envelope such that the dynamic performance of the vehicle is largely constrained. To solve this problem, this paper proposes a novel envelope control scheme based on saddle nodes position. It improves the overshoot dynamics by incorporating more stable regions in yaw rate direction and thus, improving the dynamic performance and steering agility. The simulation results indicate that compared to the previous envelope schemes, the proposed one can effectively improve the dynamic performance of the vehicle under the condition of ensuring stability.","PeriodicalId":119721,"journal":{"name":"2020 4th CAA International Conference on Vehicular Control and Intelligence (CVCI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128734592","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}
