Abstract:
A method of controlling a vehicle suspension system comprising:determining a relative velocity between a wheel and a corresponding corner of the vehicle; determining, responsive to the relative velocity, a raw wheel demand force; determining a relative position between the wheel and the corresponding corner of a vehicle body; determining, responsive to the relative position of the wheel, a scale factor, said scale factor comprising a bumpstop scale factor and a rebound scale factor, said scale factor to be the bumpstop scale factor when the relative position between the wheel and the corresponding corner of a vehicle body is in a compression region and the relative velocity is toward said compression region, said scale factor to be the rebound scale factor when the relative position between the wheel and the corresponding corner of a vehicle body is in a rebound region and the relative velocity is toward said rebound region, modifying the raw wheel demand force as a function of the scale factor to determine a scaled wheel demand force; and controlling the vehicle suspension system responsive to the scaled wheel demand force.
