The global optimal Pareto solutions of energy management strategy (EMS) play a crucial role in the development of PHEVs. This paper presents a multi-objective global optimization algorithm for the EMS of PHEVs. The algorithm combines the Radau Pseudospectral Knotting Method (RPKM) and the Nondominated Sorting Genetic Algorithm (NSGA)-II to optimize both energy conservation and battery lifespan under the suburban driving conditions of the New European Driving Cycle. The driving conditions are divided into stages at evident mode switching points and the optimal objectives are computed using RPKM. The RPKM results serve as the fitness values in iteration through the NSGA-II method. The results of the algorithm applied to a PHEV simulation show a 26.74%–53.87% improvement in both objectives after 20 iterations compared to the solutions obtained using only RPKM. The proposed algorithm is evaluated against the weighting dynamic programming and is found to be close to the global optimality, with the added benefits of faster and more uniform solutions.</p></div>","PeriodicalId":36310,"journal":{"name":"Automotive Innovation","volume":"6 3","pages":"492 - 507"},"PeriodicalIF":6.1,"publicationDate":"2023-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50102247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, recent reports of demonstrative deployments of automated vehicles (AVs) indicate that AVs are still difficult to meet the expectation of other interacting drivers, which leads to several AV accidents involving human-driven vehicles (HVs) without the understanding about the dynamic interaction process. By investigating 4300 video clips of traffic accidents, it is found that the limited dynamic visual field of drivers is one leading factor in inter-vehicle interaction accidents. A game-theoretic decision algorithm considering social compatibility is proposed to handle the interaction with a human-driven truck at an unsignalized intersection. Starting from a probabilistic model for the visual field characteristics of truck drivers, social fitness and reciprocal altruism in the decision are incorporated in the game payoff design. Human-in-the-loop experiments are carried out, in which 24 subjects are invited to drive and interact with AVs deployed with the proposed algorithm and two comparison algorithms. Totally, 207 cases of intersection interactions are obtained and analyzed, which shows that the proposed decision-making algorithm can improve both safety and time efficiency, and make AV decisions more in line with the expectation of interacting human drivers. These findings can help inform the design of automated driving decision algorithms, to ensure that AVs can be safely and efficiently integrated into the human-dominated traffic.</p></div>","PeriodicalId":36310,"journal":{"name":"Automotive Innovation","volume":"6 2","pages":"281 - 296"},"PeriodicalIF":6.1,"publicationDate":"2023-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50038384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the field of deep-learning-based automated driving, such adversarial attack threats testify to the weakness of AI models. This limitation can lead to severe issues regarding the safety of the intended functionality (SOTIF) in automated driving. From the perspective of causality, the adversarial attacks can be regarded as confounding effects with spurious correlations established by the non-causal features. However, few previous research works are devoted to building the relationship between adversarial examples, causality, and SOTIF. This paper proposes a robust physical adversarial perturbation generation method that aims at the salient image regions of the targeted attack class with the guidance of class activation mapping (CAM). With the utilization of CAM, the maximization of the confounding effects can be achieved through the intermediate variable of the front-door criterion between images and targeted attack labels. In the simulation experiment, the proposed method achieved a 94.6% targeted attack success rate (ASR) on the released dataset when the speed-speed-limit-60 km/h (speed-limit-60) signs could be attacked as speed-speed-limit-80 km/h (speed-limit-80) signs. In the real physical experiment, the targeted ASR is 75% and the untargeted ASR is 100%. Besides the state-of-the-art attack result, a detailed experiment is implemented to evaluate the performance of the proposed method under low resolutions, diverse optimizers, and multifarious defense methods. The code and data are released at the repository: https://github.com/yebin999/rp2-with-cam.</p></div>","PeriodicalId":36310,"journal":{"name":"Automotive Innovation","volume":"6 2","pages":"190 - 203"},"PeriodicalIF":6.1,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50017216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In CACC systems, connected vehicles can receive information from adjacent ones through communication networks. However, the networks are vulnerable to cyber-attacks, so the states of vehicles cannot be received promptly and accurately. This paper studies the security resilience control for a CACC system subject to denial of service (DoS) attack. The core of the proposed resilient control strategy is to estimate the delay caused by DoS attack and then compensate for it in the controller. Specifically, a CACC system is modeled by considering the impacts of DoS attack on the transmitted data. Then, a high-gain observer is presented to estimate the vehicle states including the time delay. The convergence of the observer is proved in a theorem based on the Lyapunov stability theory, and the high-gain-velocity observer is modified so that the estimation error of the velocity can converge to zero in a finite time. A resilient controller is designed by proposing a time delay compensation algorithm to mitigate the impacts of DoS attack. The effectiveness of the estimation and control methods is illustrated by a ten-vehicle simulation system operating at the FTP75 driving cycle conditions. And the relative estimation errors are less than 6%.</p></div>","PeriodicalId":36310,"journal":{"name":"Automotive Innovation","volume":"6 2","pages":"176 - 189"},"PeriodicalIF":6.1,"publicationDate":"2023-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50007671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, a hierarchical AVP path planner is proposed, which divides a complete AVP path planning into the guided layer and the planning layer from the perspective of global decision-making. The guided layer is mainly used to divide a complex AVP path planning into several simple path plannings, which makes the hybrid A* algorithm more applicable in a complex parking environment. The planning layer mainly adopts different optimization methods for driving and parking path planning. The proposed method is verified by a large number of simulations which include the verification of the optimal parking position, the performance of the planner for perpendicular parking, and the scalability of the planner for parallel parking and inclined parking. The simulation results reveal that the efficiency of the algorithm is increased by more than 20 times, and the average path length is also shortened by more than 20%.
