SUSPENSION OF SEAT FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To improve driving feeling of a driver who sits on a seat by a suspension to control vertical oscillation of the seat in corresponding to the vertical oscillation of the vehicle floor. SOLUTION: A CPU 7 in a controller 6 controls an actuator 8 in corresponding to the vertical oscillation of a vehicle floor 1. The vertical oscillation of a seat 3 is controlled by the vertical oscillation of the seat 3 in opposite direction toward the vehicle floor 1. Then, control gain to the actuator 8 is decreased in comparison with 1/2 power of vehicle speed in corresponding to the increase of vehicle speed to be detected by a vehicle speed sensor 12.
