Kinetic Dynamic Suspension System -- System Description



DESCRIPTION

  1. System description
    In the KDSS (Kinetic Dynamic Suspension System), a cylinder is installed to each of the front and rear stabilizer bars. The front and rear cylinder upper chambers and the front and rear lower chambers are each connected by a pipe. The hydraulic circuit is filled with high-pressure suspension fluid. The ECU controls the stabilizer control solenoid valves according to input signals from sensor.


FUNCTION OF COMPONENTS

Part Name
Function
Stabilizer Control ECU
  1. Closes the stabilizer control valves according to input signals from the sensor to cut the fluid flow to the accumulators.
  2. Turns on the KDSS indicator light in the combination meter to inform the driver when an abnormality is detected in the KDSS. When this happens, a DTC is stored.
Stabilizer Control with Accumulator Housing Assembly
Accumulator Pressure Sensor
Detects the pressure in the hydraulic circuit.
Stabilizer Control Solenoid Valve
Cuts the fluid flow to the accumulator.
Speed Sensor (Skid Control ECU)
Detects the wheel speed of each wheel.
Steering Angle Sensor
Detects the steering wheel's steering angle and amount of movement, and then sends signals to the stabilizer control ECU.
Yaw Rate and Acceleration Sensor
Detects vehicle's the yaw rate and acceleration and sends signals to the stabilizer control ECU.
