Electronic Suspension System (ESS)

Continuous control electronic suspension system (CCES) is the suspension system in which damper of each wheel can independently change their resistance continuously during extension and compression. The resistance or damping depends on state of road, speed of vehicle and type of driving.

Working

Types of sensors

1. Three Acceleration sensor, two front and one rear.
2. Bodywork position sensor or height sensor located near each wheel.
3. Steering sensor.

CCES system analyses information from these sensor in every 6 milliseconds and sends information to Electronic Control Unit, decides the amount of resistance to be offered on each damper. The resistance is adjusted independently by use of Electronic valve in the damper.

Electronic valve- Solenoid controlled device actuates electronic cylinder, controlled on will of controller by varying the amount of current. This electronic cylinder allows or prevents the fluids to pass into the damper. The controller varies amount of current of solenoid from 1.6 A (For sporty drive) 2.29 A (For comfort drive).

Advantages

1. Gives chassis maximum stability by controlling the spring movement.
2. Increases the control, stability and ease of handling the vehicle.
3. Gives maximum driver and passengers comfort on all type of road conditions.
4. Adapts all type of driving conditions.
