METHOD AND METHOD FOR CONTROLLING QUANTITY INFLUENCING DYNAMIC RUNNING CHARACTERISTIC OR RUNNING CONDITION OF VEHICLE

摘要

PURPOSE: To possibly optimally control in a closed loop a quantity having an influence on the running dynamic characteristic or the running condition of a vehicle. ;CONSTITUTION: A manipulated variable u is obtained through a fuzzy controller 20 from a deviation e between a target value w and an actual value y of a signal concerning a quantity having an influence on the running dynamic characteristic or the running condition of a vehicle, and a time differential of the deviation e. The manipulated variable u is fed to an actuator signal generator 16, e.g. a pulsewidth modulator which outputs a corresponding signal uPWM to an actuator 18, and hence this is suited for control of a steering system, a brake system and the chassis. Such constitution enables the deviation between a target value and an actual value to be possibly kept small under a lot of operating conditions and the control characteristics to be stabilized even in extreme cases.;COPYRIGHT: (C)1994,JPO
