Abstract
An electronically controlled air-suspension system is described
that uses sensors to detect vehicle speed, throttle position, steering
angle, height, and other factors related to vehicle attitude. Its
electronic control unit (ECU) drives the actuators to control spring
rate, damping force, and height. As a result, the system reduces changes
in vehicle attitude such as rolls, dives, squats, etc., and also
provides stable maneuverability in high-speed cruising and improved
drive characteristics on rough roads. A newly developed single-chip
microcomputer is used in the ECU. The actuators for the sporting rate
and damping force use DC motors. The system also allows drivers to
select preferred suspension characteristics from four modes, and
displays on a CRT the suspension status
