Active Seat Suspension for Ultra-Compact Electric Vehicle

Fundamental Consideration on Ride Comfort Evaluation Using Myoelectric Potential

Abstract

In recent years, several manufacturers have marketed ultra-compact electric vehicles. We suggest active seat suspension (ASS) to improve the ride comfort by the bad road run as a high value-added product. We used a voice coil motor, which is a kind of linear motor as an actuator of ASS. The ultra-compact electric vehicles are different from a normal car and the frequent riding into to the narrow way and bad road occurs. There are lot of steps and small obstacles on a road surface, and the aggravation of the ride comfort of the vehicle is expected by the comparatively low-speed run. In this study, we focused on the neck electromyogram and seat acceleration when fall from the bump. As a result, we suggested control method of the ASS considering the neck feeling of burden.
