ADAPTIVE VARIABLE SUSPENSION SYSTEM SYSTEM DESCRIPTION


  1. ADAPTIVE VARIABLE SUSPENSION SYSTEM DESCRIPTION


    1. The absorber control ECU (front acceleration sensor RH) receives signals from the sensors and switches to control the absorber control actuator (shock absorber assembly). It uses these signals to optimally control the damping force in accordance with the driving conditions and road conditions.

    Function of Components:
    Component Function
    Shock absorber assembly Absorber control actuator Changes the damping force.
    Front acceleration sensor LH Detects the vertical acceleration of the left front area of the vehicle body.
    Rear acceleration sensor Detects the rear vehicle body vertical acceleration.
    Absorber control ECU Front acceleration sensor RH

    • Controls the damping force.

    • When changed to diagnostic mode, indicates any malfunction by outputting DTCs (Diagnostic Trouble Codes).

    • Detects the vertical acceleration of the right front area of the vehicle body.
    Yaw rate and acceleration sensor Detects the vehicle's longitudinal and lateral acceleration and deceleration.
    Spiral cable with sensor sub-assembly Steering angle sensor Detects the steering direction and the angle of the steering wheel.
    Brake actuator assembly Skid control ECU

    • Sends the vehicle speed signal to the absorber control ECU (front acceleration sensor RH).

    • Sends the brake pedal depressed signal to the absorber control ECU (front acceleration sensor RH).

    • Makes a request for damping force control to the absorber control ECU (front acceleration sensor RH).
    ECM

    • Sends the drive torque signal to the absorber control ECU (front acceleration sensor RH).

    • Sends the driving mode selected using the drive mode select switch (combination switch assembly) to the absorber control ECU (front acceleration sensor RH).
    Driving support ECU assembly* Sends the damping force cooperative control signal to the absorber control ECU (front acceleration sensor RH).
    Combination switch assembly Drive mode select switch Switches the driving mode.
    Combination meter assembly Indicates the selected condition of the drive mode select switch (combination switch assembly).
