Abstract:
1. A reaction force apparatus comprising: a reaction force applying unit for applying a reaction force to an accelerator pedal; an amount-of-depression determining unit for determining an amount of depression of the accelerator pedal; a reaction force controller for controlling the reaction force applied by the reaction force applying unit depending on the amount of depression; and a rate-of-depression determining unit for determining a rate of depression of the accelerator pedal, wherein the reaction force controller sets an acceleration intention boundary threshold value, which comprises a threshold value with respect to the rate of depression, for determining whether a driver intends to accelerate quickly or gradually, and wherein the reaction force controller reduces the reaction force when the rate of depression exceeds the acceleration intention boundary threshold value, and maintains the reaction force when the rate of depression is less than the acceleration intention boundary threshold value.
