Zhang, Jindong Ren","doi":"10.4271/02-16-04-0023","DOIUrl":"https://doi.org/10.4271/02-16-04-0023","url":null,"abstract":"The interface pressure distribution is an important indicator for evaluating the\u0000 static comfort of the seat. At present, the interface pressure of a real person\u0000 is acquired through testing and used in assessing the seat comfort, which has\u0000 poor consistency and accuracy, and it is difficult to combine the test results\u0000 of different persons to make an objective evaluation. The idea is presented to\u0000 evaluate the seat static comfort by the objective interface pressure. The\u0000 H-point machine (HPM) is the standard loading device which can be used to\u0000 acquire the objective interface pressure. The test criterion was made, and the\u0000 measurement consistency of the standard loading device passed the experimental\u0000 verification. As a case study, five seats were selected to obtain the subjective\u0000 rating of static comfort and the objective interface pressure data. Based on\u0000 these data, the evaluation model of seat static comfort was established. The\u0000 above standard loading device, the objective interface pressure test criteria,\u0000 and the seat static comfort evaluation model form a comprehensive system for\u0000 assessing seat static comfort. By using the system in evaluating and optimizing\u0000 the studied seat and by the afterward validation, the method of evaluating the\u0000 seat static comfort by the objective interface pressure illustrated reliable and\u0000 accurate performance, which is easy to use and showed the good value of\u0000 engineering application.","PeriodicalId":45281,"journal":{"name":"SAE International Journal of Commercial Vehicles","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46578797","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 reduce\u0000 pollution and energy consumption, major wheel loader manufacturers are\u0000 developing electric powertrain technology.

This study is intended to\u0000 build a vehicle simulation model of a multiple drive motor electric loader.\u0000 According to the common working conditions and empirical formulas of the loader,\u0000 the simulation data of the electric loader are calculated.

In order to improve the stability of\u0000 the autonomous vehicle on the curved road, this article presents a pre-emptive\u0000 braking control method based on V2X technology. Instead of using the active\u0000 safety system to try to stabilize the vehicle in case of danger, the pre-emptive\u0000 braking action is proposed to reduce the vehicle speed in advance to a level\u0000 that allows safe navigation of the turn to avoid danger. It is assumed that the\u0000 friction and curvature of the curved road ahead can be obtained through V2X\u0000 technology. Combined with a linear two degrees of freedom (2-DOF) bicycle model,\u0000 an optimal control method is adopted to calculate the front and rear wheel\u0000 steering angles to track the centerline of the curve lane. A more complex\u0000 vehicle dynamics model established earlier is selected for simulation analysis\u0000 to verify the proposed control method. The results show that the proposed\u0000 control method can improve greatly the stability of the autonomous vehicle on\u0000 the curved road.","PeriodicalId":45281,"journal":{"name":"SAE International Journal of Commercial Vehicles","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42199103","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}
