Abstract
In a 'steer-by-wire' vehicle steering control system which steers steerable wheels with a powered actuator according to an input signal obtained from a sensor associated with a steering wheel, to the end of achieving an optimum vehicle response to a steering input, a compensatory transfer function is introduced between the steering wheel and the powered steering actuator. The compensatory transfer function can be obtained by suitable manipulation of the transfer functions of the hardware involved and a desired overall transfer function. The frequency domain compensatory transfer function is transformed into a time-domain input-output relationship, and the steering mechanism is actuated accordingly as a real time operation. By suitable selection of the desired overall transfer function, it is possible to achieve a vehicle response both stable and favorable.
