Continuous Damping Control SYSTEM

System Description


Description

- The Continuous Damping Control system mainly consists of the components such as the E-SUS control unit, front body vertical G sensor, front wheel vertical G sensor, rear body vertical G sensor, and shock absorber actuators on each wheel.
- It calculates the command values to be transmitted to the shock absorber actuator on each wheel based on the information from ECM, ABS actuator and electric unit (control unit) and steering angle sensor via CAN
communication and information from the front body vertical G sensor, front wheel vertical G sensor and rear body vertical G sensor.
- 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.
- Communicates the signal from each control unit via CAN communication.





Operation principle






Controls damping force by changing the oil passage cross section area through control of orifice by solenoid core activation.

Operation characteristics






- Changes the damping force control by switching the switch (AUTO
mode or SPORT mode).





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