摘要： A method and system for controlling a vehicle suspension system comprise determining a relative velocity between a wheel and a corresponding corner of the vehicle, and determining responsive to the relative velocity a raw wheel demand force. The method and system also comprise determining a relative position between the wheel and the corresponding corner of a vehicle body, determining a scale factor responsive to the relative position of the wheel, 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.

摘要： A method, system and computer readable medium storing a computer program is provided for independent control of a variable force damper system. The variable force damper system can be applied to control a vehicle suspension system. The system provides individual wheel control independent of vehicle body forces. In operation, at least one relative velocity signal and at least one body demand force is received. At least one body damper command is determined based on the body demand force. At least one wheel motion indicating parameter is determined based on the relative velocity signal. At least one wheel damper command is determined based on the wheel motion indicating parameter and a damper command is determined based on the larger of the body damper command and the wheel damper command.
