Suspension: Description and Operation

System Outline

Electric modulated suspension system is the damping force control system using several signals which restrains the vehicle movement (Such as rolling, diving, and squad) by a driver's operation together with restraining and absorbing the vehicle movement change and vibration against the unevenness of the road.

1. Steering sensor signal
To input the rotation angle of the steering wheel into the TERMINALS SS2+ and SS2- of the absorber control ECU.

2. Speed sensor signal
To detect the vehicle speed at ABS speed sensor front RH, and input to the TERMINAL FRO of the absorber control ECU from skid control ECU with actuator.

3. Stop light SW signal
To detect the signal of the brake in operation and input it into the TERMINAL STP of the absorber control ECU.

4. Engine rotation signal
To detect the engine speed and input it into the TERMINAL TACH of the absorber control ECU.

5. Absorber control SW signal
To detect the switch condition and input it into the TERMINALS SW1 and SW2 of the absorber control ECU.
