The Real Time Damping (RTD) system independently controls
a solenoid in each of the four shock absorbers in order to control the vehicle
ride characteristics. The RTD system is capable of making these
changes within milliseconds. The RTD system consists of the following
major components:
| • | The front/rear adjustable shock absorbers |
| • | The shock absorber electrical solenoids (integrated within the
shock absorbers). |
| • | The front/rear position sensors |
| • | The ride control switch |
| • | The electronic suspension (ESC) module |
The RTD system has the following three shock damping control settings:
| • | TOUR -- a smooth, soft ride |
| • | SPORT -- provides more feel/response to road conditions |
| • | PERF -- Provides tight, firm ride and precise response to
road conditions. |
The ESC controls the damping mode selection according to the following
factors:
| • | The chassis pitch input |
| • | The body to wheel displacement |
| • | The ride control switch position |
The ESC module evaluates these inputs in order to separately control
the solenoid valve position in each of the shock absorbers, providing an enhanced
ride and comfort level over the widest possible range of operating
conditions.
