This research aims to quantify driver ride comfort due to changes in damper characteristics between comfort mode and sport mode,considering the vehicle’s inertial *** comfort of riding in an automobile has been evaluated in recent years on the basis of a subjective sensory evaluation given by the ***,reflecting driving sensations in design work to improve ride comfort is abstract in nature and difficult to express ***,we evaluated the human body’s effects while driving scientifically by quantifying the driver’s behavior while operating the steering wheel and the behavior of the automobile while in motion using physical *** this end,we collected driver and vehicle data using amotion capture system and vehicle CAN and IMU *** also constructed a three-dimensional musculoskeletal mathematical model to simulate driver movements and calculate the power and amount of energy per unit of time used for driving the joints and muscles of the human ***,we used comfort mode and sport mode to compare damper characteristics in terms of *** comfort mode,damper characteristics are soft and steering stability is mild,but vibration from the road is not easily transmitted to the driver making for a lighter load on the *** sport mode,on the other hand,damper characteristics are hard and steering stability is comparatively ***,vibration from the road is easily transmitted to the driver,whichmakes it easy for a load to be placed on the *** a result of this comparison,it was found that a load was most likely to be applied to the driver’s *** result in relation to the neck joint can therefore be treated as an objective measure for quantifying ride comfort.
