The full paper begins with a review on structure and main shortcoming of existing hydraulic pump, resulting in, in our opinion, the conclusion that it is absolutely essential to study on the Electro-Hydraulic Pump(EHP), a highly integration of electric motor and hydraulic pump. We now present a model how to get temperature field of our design plunger EHP that we believe that it can much better develop the EHP. In the full paper, we explain our method in some detail; in this abstract, we just add some pertinent remarks to naming the topics, such as motor thermal model, the fluid model and the heat conduction model. We discuss the temperature distribution under the condition of relationship among the oil film thickness, overall efficiency, leakage and cooling capacity. Finally we perform simulations in ANSYS. The simulation results, shown in the full paper, show preliminarily that our method for the temperature field is efficient to design the EHP.","PeriodicalId":151322,"journal":{"name":"International Conference on Vehicular Electronics and Safety","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116579517","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}

Especially in urban environments with pedestrians there are many different situations. The prediction of future movements with 100% certainty is impossible, if the intention of the pedestrian is unknown. In this paper, reachability analysis is used based on historical movement data. A state of the art motion planning approach with Mixed-Integer Linear optimization (MILP) is used for the trajectory planning of the vehicle. This approach can also be used for cooperative vehicle systems, with historical movement data in a fixed urban environment (e.g. intersection). The advantage of this approach is that prior knowledge can be incorporated in the reachability analysis, and the computional load is scalable.","PeriodicalId":151322,"journal":{"name":"International Conference on Vehicular Electronics and Safety","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115418777","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}

During the topological reconstruction process, the time complexity is reduced by using an additional index table. By calculating the normal variance and maximum deviation of triangular facets connected to a vertex to determine the important degree of the vertex, and adding it to QEM as weights. Compared with the Garland algorithm, the use of half-edge structure can directly gain the adjacency relation, and accelerate the speed of the model simplification. Experiment shows that new error metric formula can exactly measure the simplification error, the simplification speed and the effect of the model are both satisfied.","PeriodicalId":151322,"journal":{"name":"International Conference on Vehicular Electronics and Safety","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125723382","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}
