Ride comfort in road vehicles: a literature review

Passengers and the driver in vehicles are subjected to vibrations, noise, acceleration, etc., which affect the comfort, activity and health of people. The effect of vibrations on the human body depends on their frequency, amplitude, duration and direction of impact. Prolonged exposure to vibration causes fatigue in the driver and passengers, which reduces their performance and worsens their functional condition. This can affect traffic safety, so one of the main requirements for modern vehicles is to increase ride comfort. The ride comfort is a set of conditions, impacts and sensations of the driver and passengers when traveling in vehicles. Over the years, there have been many studies and scientific developments aimed at measuring, evaluating and analysing the various factors that affect ride comfort . This paper presents a review on the research studies that have been done on dynamic factors that affect the ride comfort in road vehicles and methods used for measurement and its evaluation were discussed. Finally, some existing suggestions for improving the ride comfort in road vehicle are presented.
