The Future Development and Analysis of an Electric Active Suspension System

The driver's response is an important consideration for developing an advanced vehicle control system. Drivers' response to vehicle motion was investigated here using a rotary type electric active suspension system that could control roll, pitch, and bounce. The system allowed control of vehicle attitude and ride comfort based on an inertial input and road input with sky-hook logic. Drivers' reaction differences when subjected to both smaller and larger roll angles produced by the active suspension were examined.
