ABSTRACT:
Reactive force control apparatus for a pedal comprises: a movement detection section that detects movement of the pedal; a solenoid that produces a reactive force in response to operation of the pedal; a reference reactive force impartment table defining intensities of the reactive force corresponding to amounts of the operation of the pedal; a setting value input section operable to input a setting value for changing the reactive force responsive to the operation of the pedal; and a control section that controls the reactive force to the pedal by changing content of the table, on the basis of the input setting value, to thereby create a changed reactive force impartment table, so that the reactive force to the pedal is controlled on the basis of the changed table and detected movement of the pedal.
