ABS의 PEDAL FEELING 개선

Despite short history, ABS is wide-spread even to small cars, which brought us a new concept in ABS. While ABS price is being lowered to enable car makers to install one without considerable up-cost, we meet another tendancy to develop pedal feeling improved version of ABS modulator especially for luxury cars. In this study, kick-back mechanism was investigated and with the result of which new hydraulic circuit was proposed to improve pedal feeling based on current ABS modulator being produced by Mando. New ABS modulator was developed, followed by design of parts and packaging needed accordingly. Evaluation of new modulator via rig test and vehicle test shows that the pedal feeling is successfully enhanced.
