A effective method is model predictive control (MPC), which has been successfully applied to typical multi-input multi-output (MIMO) system with fast dynamics, actuator constraints, and strong couplings, such as diesel engines. In MPC controller design, the choice of output variables has a direct impact on the resulting control performance. Through investigating and discussing different selections of outputs, we propose that it is beneficial to select EGR-fraction and boost pressure as output variables while setting the oxygen fuel ratio as a constraint. Besides, equipping an integral action on the EGR ratio can improve the control performance.","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":"130143959","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 this paper, a vehicle trajectory prediction encoder-decoder model based on Gated Recurrent Unit (GRU) with attention mechanism is proposed. The proposed model is comprised of intention recognition module and trajectory prediction module. The intention recognition module was employed for recognizing driver's intention and calculating the probabilities of turning-left, lane-keeping, turning-right. The trajectory prediction module predicts vehicle trajectory using GRU decoder with attention mechanism, which takes vehicle historical position as input and predicts future position. Both intention recognition module and the trajectory prediction module share one encoder to save time. The NGSIM dataset was employed for training and testing. The experimental results indicate, comparing with traditional methods, the proposed horizontal-longitudinal decoupling hierarchical trajectory prediction method based on GRU neural network can predict driver's desired vehicle trajectory in a long prediction horizon and the attention mechanism improve the trajectory prediction accuracy at the same times.","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":"129441445","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}

So a two-parameter fuzzy control method is proposed to adjust the filling oil pressure and the built model is used to verify the effectiveness of the algorithm.

The coupled roll and yaw dynamics model and quarter suspension model are firstly established. Considering road unevenness is the main factor which causes vertical vibration and discomfort, a simple method to evaluate road unevenness with vertical acceleration of sprung mass is proposed. The coupled roll and yaw dynamics model is simplified to a prediction model with lower computational cost, and then an MPC controller is designed. Three different cost functions of comfort, yaw tracking and rollover avoidance respectively are designed, and their switching strategy is proposed according to priorities. Simulation results show that control strategy proposed in this paper is effective to reduce discomfort, overshoot of yaw rate and risk of rollover.","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":"124447132","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}

Current research on vehicle speed prediction mainly focuses on adapting to the dynamics, random and complex driving environment, while rarely takes drivers' driving preferences into account. In this paper, a learning-based prediction model consisted of an oriented Hidden Semi-Markov model (Oriented-HSMM) and an optimal preference speed prediction algorithm is proposed to leverage drivers' driving preferences into vehicle speed prediction. The Oriented-HSMM is developed to learn the spatial-temporal coherence of drivers' driving preference states under different traffic conditions and infer its long-term sequences in position domain. Based on these preference states, the optimal speed prediction algorithm using preference dynamics features is designed to retrieve the speed trajectory with maximal likelihood. To show its effectiveness, the proposed method is tested with the Next Generation Simulation (NGSIM) data on the US101 dataset comprising with the Hidden Markov model (HMM) and HSMM without considering driving preferences. Experiment results indicate that the proposed algorithm obtains the best performance with the mean absolute error (MAE) of 4.15 km/h and the root mean square error (RMSE) of 0.7603 km/h at 200 m prediction horizon.","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":"124562340","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}
