ELECTRONICLL MODULTED IR SUSENSION SSTEM OUTLINE THIS SSTEM CONSISTS OF NEUMTIC CLINDER WHICH HS RESSURED IR IN N IR CHMBER, N ECU WHICH UTOMTICLL SWITCHES THE SRING RTE ND VEHICLE HEIGHT BETWEEN TWO RNGES (NORML ND HIGH) CCORDING TO THE DRIVING CONDITIONS ND LSO TWO (2) MODES (NORML ND HIGH) WHICH THE DRIVER CN CHOOSE FROM CCORDING TO REFERENCE. LSO, THE DMING FORCE OF THE SHOCK BSORBER IS UTOMTICLL SWITCHED B THE ECU BETWEEN THREE LEVELS (SOFT, MEDIUM ND HRD) ND THE DRIVER CN CHOOSE ONE OF TWO (2) MODES (NORML, SORT) CCORDING TO REFERENCE. COMBINED CONTROL OF THE SRING RTE, VEHICLE HEIGHT ND DMING FORCE SURESSES CHNGES IN THE VEHICLE S TTITUDE SUCH S ROLL, NOSE DIVE ND SQUT TO ROVIDE OUTSTNDING RIDING COMFORT ND CONTROLLBILIT.. INUT SIGNLS () STEERING SENSOR SIGNL ROTTION NGLE OF THE STEERING WHEEL IS INUT TO TERMINL SS ND SS2 OF IR SUSENSION ECU.

THEN, THE CURRENT FLOWS TO THE HEIGHT CONTROL EXHUST VLVE INSTLLED IN THE HEIGHT CONTROL DRER, CONTROL OF THIS CURRENT B THE IR SUSENSION ECU CUSES THE VLVE TO OEN SO THT THE IR INSIDE THE NEUMTIC CLINDER IS EXELLED ND THE VEHICLE HEIGHT IS LOWERED. 50
3. BSIC OERTION OF SUSENSION CONTROL CTUTOR THE SUSENSION CONTROL CTUTOR CONTROLS THE DMING FORCE OF THE SHOCK BSORBER INSIDE THE NEUMTIC CLINDER IN 9 STES. BSED ON SIGNLS FROM THE CCELERTION SENSORS, VEHICLE SEED SENSOR ND STO LIGHT SWITCH, ETC., THE SUSENSION ECU CONTROLS THE SUSENSION CONTROL CTUTOR TO DJUST THE DMING FORCE OF THE SHOCK BSORBER.
