A long commute is often stressful and tiring, so comfortable seating becomes increasingly important for drivers as well as passengers. In order to efficiently evaluate seats in terms of vibration ride, an objective algorithm that can predict the subjective perception of seat vibration is required.

Vibration induced by powertrain, ancillaries and road can dramatically affect how passengers judge the quality of the ride. If you continue to browse the site, you will accept our use of cookies. While the on-road subjective assessment provides more realistic ratings of seat vibration quality, it is not cost-effective and does not provide the subjects with the possibility of back-to-back comparisons, that is, comparing two or more different seats, one after another, within the same experimental session.

Vibration Roughness explained our subjective data better than the traditional measuting using only vibration energy, and the predicted results were less affected by the sensor locations and directions.

Many studies have been done to predict the subjective perception of riding vibration comfort. A comfortable and pleasant ride is an important factor for drivers and passengers alike when they decide which vehicle to buy.

ISO is the most often used standard for this purpose.
