SUSPENSION Vehicle Dynamic Suspension
The vehicle dynamic suspension system is designed to control excessive body motions in bounce, pitch and roll
while maintaining/improving ride and feel. The system controls the settings of the four vehicle dampers
between firm and soft based on the road conditions and driver inputs.
The system uses the three accelerometers, vehicle speed and the brake switch status to calculate the vehicle
motion. The vehicle speed and brake status information is passed to the module on the SCP network. The
module then calculates the bounce, pitch and roll of the vehicle and adjusts the dampers to change the ride state.
This will only occur at speeds over 3 mph (4 kph).
