Purpose Of The Systems: Notes
The E65 chassis offers the driver optimum ride comfort, driving safety, good agility and excellent handling. The chassis also adapts to changes in road conditions: traffic, ice, snow etc. Vehicle speed and changes in the direction of travel generate forces that have an effect on the chassis which requires the driver to react correctly to maintain safe driving.
The following forces occur while driving:
- Vertical forces - uneven road surfaces, bumps and potholes
- Lateral forces - centrifugal forces during cornering and crosswinds
- Longitudinal forces - acceleration, deceleration and braking
The following vehicle structure movements occur as a result of these forces:
- Around the transverse axis: pitch
- Around the longitudinal axis: roll
- Around the vertical axis: yaw
Active Driving Dynamics Systems are integrated in the E65 chassis which support the driver both actively and passively by suppressing the effects of these forces as much as possible. The Driving Dynamics Systems include:
- Dynamic Stability Control (DSC) with subsystems
- Electronic Damping Control (EDC-K) continually adjustable system
- Dynamic Drive active roll stabilizer bar (ARS)
The Driving Dynamics Systems monitor the driving conditions using sensors. The sensor signals are transmitted to the control modules that interpret and evaluate the driving conditions. The control modules send output signals to actuators that will counter these forces providing adaptation for the road and driving situations.
