Claim 8:
9. A suspension control system for a vehicle comprising:
one or more adaptive suspension components connected to the vehicle, each having one or more adaptive suspension settings;
a suspension control unit (SCU) that is arranged in electronic communication with said adaptive suspension components;
an unsprung mass accelerometer positioned at each wheel of the vehicle, where each unsprung mass accelerometer is arranged in communication with said suspension control unit (SCU) and is configured to provide unsprung mass acceleration data to said suspension control unit (SCU);
at least one forward looking sensor mounted to the vehicle that is arranged in communication with said suspension control unit (SCU) and configured to provide sensor data about approaching road irregularities to said suspension control unit (SCU);
said suspension control unit (SCU) is programmed to determine if a road event is approaching based on said sensor data and provide pre-emptive road event classification information for an approaching road event;
said suspension control unit (SCU) is programmed to set both a threshold based suspension pre-setting and a threshold based pre-trigger based on said pre-emptive road event classification information;
said suspension control unit (SCU) is programmed to monitor said unsprung mass acceleration data and calculate a slope value for said unsprung mass acceleration data;
said suspension control unit (SCU) is programmed to arm an event detection flag if said unsprung mass acceleration data exceeds said threshold based pre-trigger; and
said suspension control unit (SCU) is configured to generate a control signal that changes said adaptive suspension settings of said adaptive suspension components if said unsprung mass acceleration data exceeds said threshold based pre-trigger and said slope value that is calculated by said suspension control unit (SCU) exceeds a maximum slope value.
