Damping of the wheel movements as well as body movements

To dampen the wheel movements and body movements, the motion of the vehicle is monitored. Here, the following axes are included:

• Vehicle vertical axis
• Vehicle lateral axis
• Vehicle longitudinal axis

The following signals, e.g., are used for monitoring:

• Pitch rate, roll rate, vertical acceleration
• Wheel acceleration
• Driving speed
• Lateral acceleration and longitudinal acceleration

The signals are used to calculate the required level of damping force.

The Electronic Damper Control dampens the body movements to enhance comfort. Electronic Damper Control dampens the wheel movements to enhance safety. The aim is to prevent the wheels from losing contact wtih the roadway. Depending on the situation, optimized vertical force must be assured.

Electronic Damper Control also takes account of lateral acceleration (e.g. transition from straight-ahead driving into a curve). If a rise in lateral acceleration is detected, the EDC control unit shuts down as the vehicle starts to negotiate a bend in the road. This means that the shock absorbers can be activated accordingly in advance. This means that the Electronic Damper Control contributes to reducing the rolling motion of the vehicle.

Electronic Damper Control also detects braking and driving off. To achieve this, the DSC provides the brake pressure signal. High levels of brake pressure normally lead to a pitching motion of the vehicle. EDC counteracts this pitching motion through targeted control interventions.

Depending on the applicable customer request, the drive dynamic control switch can be used by the EDC control unit to adjust the damping force characteristics. A positive influence on control of driving safety is a feature of every program.
