ABSTRACT:
A steering characteristic controller for a power steering system of the type that an actuator operable in response to an electric current thereto varies the characteristic of a assisting power generated by a power steering gear. The controller includes a signal converter responsive to a signal from a vehicle speed sensor for converting the vehicle speed signal into a voltage signal corresponding thereto and a drive circuit connected to the actuator for driving the same in response to the voltage signal from the signal converter. The controller further includes a gain adjuster, which varies the output gain of the voltage signal from the signal converter in correspondence to the magnitude of a signal from a vehicle load sensor.
