Ride Control

DUAL ACTION SYSTEM
^ The semi-active ride control system reads the height sensor travel every 5 milliseconds. That equals once every 152 mm (6 inches) when the vehicle is traveling at 100 km/h (60 mph).
^ The height sensors lengthen and shorten to respond to changes in the road surface. The rougher the road, the greater the change in height sensor length in short time periods. This causes large height sensor signal changes in short time periods to the vehicle dynamics module.
^ Each shock absorber is adjusted in response to the signal from the height sensor located at the nearest corner.
^ The shock absorbers will switch to the hard valving required by a rough road surface when the suspension is traveling from expansion to compression (from rebound to jounce).
^ The shock absorbers will switch to a soft valving when the vehicle dynamics module does not see a height sensor signal showing high rates of change. Like the switch to hard valving, the switch takes place during the chance from rebound to jounce.
