Electromechanical Active Body Control

The development of an active electromechanical suspension system is discussed which aims to reduce energy consumption and assembly costs whilst meeting ride comfort and driving dynamics requirements. This paper covers the part of the project dealing with the development of the modules, measurements at the test rig, integration into a prototype vehicle and the results from driving tests. The principle of the system is outlined and comparisons made with hydraulic actuators. Key factors in the conceptual design process are listed. The use of object-oriented simulation in a number of aspects of the design of the spring strut module is described. The integration of the system into the vehicle is described and details given of the operation of the lateral dynamics, vertical dynamics and spindle position controllers. Test results are presented graphically and show a reduction in roll angle and higher roll damping. A reduction in fuel consumption is also demonstrated which compares favourably with hydraulic systems.
