Patent ID: 8082081

Claim:
A vehicle control system disposed within a vehicle, the vehicle control system comprising: a first control unit and a second control unit that respectively store the same vehicle vibration model on a computer readable medium that is separated into a vehicle body vibration model, a chassis vibration model and a tire vibration model to estimate vibration states of various portions of a vehicle; and a first operation device and a second operation device, which are controllable by the first control unit and the second control unit, respectively, to change motion states of the vehicle, wherein the first control unit and the second control unit receive the same input parameters to be input to the vehicle vibration model and calculate estimated vibration states of the various portions of the vehicle, respectively, wherein the first control unit and the second control unit share subject models to be controlled in vibration suppression among the vehicle body vibration model, the chassis vibration model and the tire vibration model, wherein the first control unit and the second control unit calculate control quantities according to the vibration states in the subject models to control the first operation device and the second operation device, respectively, and wherein the first control unit calculates estimated vibration states at a first frequency and the second control unit calculates estimated vibration states at a second frequency, the second frequency being different than the first frequency.
