Actively controlled suspension system for suppressing attitude change of vehicular body

摘要

A suspension control system detects acceleration exerted on the vehicular body and close to a predetermined critical value. When the acceleration greater than the predetermined critical value, total stiffness of the suspension system is adjusted to be smaller value to allow attitude change of the vehicle body in a predetermined magnitude. Therefore, rolling or pitching is caused as a sign that traction of the suspension tends to break. This makes a driver to recognize that the vehicular driving condition is near the critical condition.
