ACTISEAT: Active vehicle seat for acceleration compensation

Abstract This paper describes an active vehicle seat to isolate the equipment and passengers in a vehicle from vibration and to compensate, to a certain extent, for acceleration in all directions. The main objective of this system is to reduce the negative effects of vibration and acceleration on embarked equipment and passengers. The active seat is composed of three main subsystems: A motion sensor unit installed on the vehicle body, to acquire the main motion parameters of the vehicle: speeds, accelerations, inclinations, etc. A small motion base attached to the seat. This platform moves actively, driven by a set of actuators. A control system for the overall system command. The seat has been extensively tested and the main results are presented.
