Bilstein DampTronic SYSTEM

Bilstein DampTronic

System Diagram

Description

The Bilstein DampTronic system mainly consists of the components such as the E-SUS control unit, front vertical G sensor, rear vertical G sensor, and shock absorber actuators on each wheel.
It calculates the command values to be transmitted the shock absorber actuator on each wheel based on the information from ECM, ABS actuator and electric unit (control unit) and steering angle sensor and information from the front vertical G sensor and rear vertical G sensor via CAN communication.
The shock absorber actuator on each wheel controls the damping force based on the command values calculated by E-SUS control unit.
Can perform the self-diagnosis with CONSULT-III.

Communicates the signal from each control unit via CAN communication.

Control unit	Signal status
Steering angle sensor	Transmits mainly the following signals to E-SUS control unit via CAN communication. Steering angle speed signal
ABS actuator and electric unit (control unit)	Transmits mainly the following signals to E-SUS control unit via CAN communication. Vehicle speed signal Brake pressure control signal Stop lamp switch signal ABS operation signal Side G sensor signal
ECM	Transmits mainly the following signals to E-SUS control unit via CAN communication. Engine speed signal

Operation principle

When the shutter is closedBecause the shutter (2) is closed (A) by the solenoid core (1), the maximum oil channel resistance and high damping force are obtained.

: Oil passage

When the shutter is openBecause the shutter (2) is opened (A) by the activated solenoid core (1) and the oil flows through 2 different passages, the minimum oil flow rate and low damping force are obtained.

: Shutter moving direction

: Oil passage

Operation characteristics

Changes the damping force range image of the shock absorber by switching the switch.

Changes the damping force depending on the output current to the shock absorber actuators.
