F97/F98￿Complete￿Vehicle
5.￿Chassis￿and￿Suspension
5.4.3.￿Integrated￿actuation￿(longitudinal￿transverse￿dynamics)
What￿is￿known￿as￿integrated￿actuation￿is￿used￿on￿the￿F97/F98.￿The￿integrated￿actuation￿in￿the￿M￿DSC
comprises￿the￿DSC,￿which￿is￿responsible￿for￿the￿longitudinal￿dynamics,￿and￿an￿transverse￿dynamics
management￿control￿unit￿(QDM)￿integrated￿in￿the￿DSC￿control￿unit.￿This￿means￿that￿the￿current
driver's￿choice￿is￿distributed￿to￿the￿appropriate￿actuator￿via￿this￿M￿DSC￿control￿unit.￿That￿results￿in￿the
following￿benefits￿when￿driving￿the￿F97/F98:
• Excellent￿traction,￿especially￿on￿low￿coefficients￿of￿friction
• M-specific￿agility￿and￿playfully￿intuitive￿control￿of￿the￿vehicle
• Superiority￿in￿every￿day￿use
• Variable￿functions￿of￿the￿M￿xDrive￿are￿possible,￿depending￿on￿the￿driver's￿choice.
The￿actuator￿and￿control￿units￿that￿are￿used￿depending￿on￿the￿driver's￿choice￿are:
• M￿Servotronic￿(M￿EPS)
• M￿VDP￿Electronic￿Damper￿Control￿(EDC)
• M￿regulated￿M￿rear￿axle￿differential￿lock￿(M￿GHAS)
• M￿Dynamic￿Stability￿Control￿(M￿DSC)
• M￿transfer￿box￿(M￿VTG)
• Digital￿Motor￿Electronics￿(DME)
The￿transverse￿dynamics￿management￿control￿unit￿QDM￿is￿not￿a￿separate￿control￿unit,￿but￿is
integrated￿in￿the￿M￿DSC.￿It￿therefore￿cannot￿be￿replaced￿separately.
