In recent years, the automotive sector has experienced increasing competition between different manufacturers. It is in this sense that interior comfort represents one of the areas for improvement to meet customer needs. The level of comfort can be assessed at all stages of vehicle use: Whether stationary or moving at low or high speed, whether driver or passenger. Vehicle occupants can always estimate the comfort of their location. The interior comfort of vehicle is related to some phenomena such as: noise, vibration. Vibration is one of the major sources of discomfort. The main goal of this paper is to study vehicle interior vibration. We present experimental study and measurement of vehicle interior vibration by referring to some parameters: Vehicle characteristics, speed and traffic conditions. The experimental procedure has taken place in two different sites: an urban segment and a rural segment using a vehicle type Citroen C4. The vibration acceleration signals were measured in three dimensions (x-axis, y-axis, z-axis). Measurement results demonstrate that engine is the main source of vibration and in the other hand the speed as an important parameter that influence the vehicle interior comfort quality. Also, the vibration level changes with the position of accelerometers in the vehicle.
