Analysis Of Electric Bus Ride Comfort Based On Motion Sickness

With the rapid development of electric vehicle technology and the strong support of national policies,electric buses are widely promoted in major cities due to their advantages of energy conservation and emission reduction,and the problem that electric buses are more likely to be motion sickness in response to passengers has become an important factor affecting the popularity of electric buses.Therefore,it is necessary to explore the influencing factors of motion sickness,ride comfort,and the influence of motion sickness on ride comfort of pure electric buses from the vehicle structure,so as to put forward targeted improvement suggestions for bus companies,bus companies,governments and passengers.Based on the full analysis of the existing theoretical basis and the body structure of pure electric buses,this paper selects five influencing dimensions of visual perception,motion sickness,lateral vibration,vertical vibration and interior environment,and constructs a questionnaire based on the dimension of ride comfort,and comprehensively designs a questionnaire to explore the influence of individual factors on motion sickness and ride comfort.After sorting and coding the collected data,descriptive statistical analysis and difference analysis were carried out on the survey questionnaire,the reliability and validity of the scale were tested,and the structural equation model analysis method was used to construct a pure electric bus riding comfort model based on motion sickness for the overall sample,motion sickness sample and non-motion sickness sample,and the model hypothesis was tested and the model path was compared and analyzed.The study found that half of bus passengers sometimes feel motion sickness,and younger passengers and women are more likely to get motion sickness,one-third of passengers agree that pure electric buses are more likely to get motion sickness and will change their travel mode because of motion sickness,in addition,the rear position and half-hour ride time of the vehicle are more friendly to motion sickness passengers.For pure electric buses,lateral vibration,interior environment,motion sickness,vertical vibration and visual perception affect the ride comfort in turn,lateral vibration and visual perception affect motion sickness,while vertical vibration and the interior environment have no significant impact on motion sickness,and motion sickness significantly affects ride comfort.In addition,passengers with motion sickness are more likely to achieve satisfactory ride comfort than non-motion sickness passengers,and the impact of motion sickness on their ride comfort is more important.Finally,suggestions for improvement are put forward for bus companies,bus companies,governments and passengers.
