Electronic Suspension Control Description and Operation: Notes

The electronic suspension control system individually controls the damping force of each of the 4 shock absorbers in order to keep the vehicle body as calm as possible. Changes of the damping forces can be accomplished within milliseconds. Suspension characteristics can be changed at any time by activating the sport mode or tour mode.

The electronic suspension control system consists of the following major components:

• The suspension control module
• Two front and one rear vertical suspension displacement sensors
• Four shock absorber actuators, which are integrated within the shock absorbers

The suspension control module controls the damping forces according to the following factors:

• Vehicle speed
• Steering wheel position
• Engine torque
• Brake pressure
• Electronic Suspension Position Sensor
• Internal multi-axis acceleration sensor
• Internal multi-axis angular sensor

The suspension control module evaluates these inputs in order to separately control the shock absorbers, providing an enhanced ride and comfort level over the widest possible range of operating conditions.
