ADC 2 is said to combine lateral and body control to deliver enhanced performance and safety and TRW already has three development contracts for this technology, working with vehicle manufacturers in Europe, North America and Asia Pacific.


A spokesman said TRW’s Active Dynamic Control Systems (ADC) help to resolve the conflict between ride comfort and handling by replacing the rigid drop links of one stabiliser bar end with a hydraulic actuator controlled by an electro-hydraulic-control-unit (EHCU) with information about driving conditions fed in via sensors.


“We have developed the EHCU from proven braking technology and the actuator based on a system used for hydraulic steering.  We have, naturally, modified these components to meet the additional functionality requirements. With the interaction of these components we have achieved a cost effective, high quality and robust product.”


The portfolio of active control systems products now includes ADC 1, a lateral dynamic control system; Active Roll Control — designed for body roll control; and the more sophisticated product ADC2.

The new system combines the lateral dynamic control capabilities of the ADC1 system with the body roll control function of the ARC system. ADC2 has two degrees of freedom by controlling two hydraulic circuits (front and rear) independently.


ADC2 is designed for sporty luxury cars, sedan cars and SUVs from the mid-size to premium segment.
