Introduction
Modern chassis and suspensions must offer drivers optimum driving comfort, high driving safety, a high degree of agility and simple handling. Furthermore, it must also be able to adapt to changed conditions (road and traffic conditions, ice, snow etc.). The following movements of the vehicle body can occur as a result of the acting forces:
-About the transversal axis: pitching
-Around the longitudinal axis: rolling
-About the vertical axis: yawing
The task of the chassis and suspension is to suppress the effects of these forces as much as possible. Active driving-dynamics systems are integrated in the E65 which support the driver both actively and passively.
The driving-dynamics systems record the driving conditions using the sensors. These are transmitted to the control units which then convert the input signals and send output signals to the relevant actuators.
The driving-dynamics systems include:
-The Dynamic Stability Control (DSC) with subsystems
-The continually adjustable Electronic Damping Control system (EDC-K)

ABS/ASC/DSC
通用自动驾驶汽车Introduction
Bosch DSC 5.7 has been improved in detail and expanded to include new functions in order to achieve improved system operation.
The system is connected to the PT-CAN.
Functions (overview)
The DSC module controls by means of brake intervention or for individual situations by means of engine-load control.It consists of the following subsystems:
-ABS Anti-lock Braking System
-ASC Automatic Stability Control
-MSR Engine drag-torque control
-DSC Dynamic Stability Control
-DBC Dynamic Brake Control
-CBC Cornering Brake Control
-ECD Electronically Controlled Deceleration (with ACC only) -FBS Fading Brake Support
-FLR Driving-performance control
-DTC Dynamic Traction Control
-Parking brake (hydraulic section)
In addition, the evaluation of the 2-stage brake-lining wear sensors has been integrated in the DSC control unit.
The setup and mode of operation of the brake-lining wear sensors is described in the Background Material "Brakes."
