Electronic Suspension System Control Utilizing ABS System Wheel Speed Sensors 1999-01-3079

This paper describes a semi-active damping control system that responds in real-time to road and driving conditions based on body motions as determined through ABS wheel speed sensors. The use of these existing sensors for vehicle information eliminates the need for the additional sensors (e.g. accelerometers and body-to-wheel position/velocity sensors) that are commonly part of semi-active suspension systems. This technology also allows for further cost and part count reductions through the combination of the suspension and brake controls into a single electronic control unit.
This paper has been previously presented in 1998 at the SAE Controlled Suspension System Toptec.
