In an accelerator pedal effort control apparatus which increases a pedal effort of an accelerator pedal 2 when an accelerator opening angle is larger than a predetermined accelerator opening angle threshold value, in a case where a steering angle of a steering wheel when a vehicle driver starts to increase an opening angle of accelerator pedal 2 is small, a pedal effort increment is a reference pedal effort increment (ΔF) and, in a case where the steering angle is large, is a relatively small pedal effort increment (ΔF−β). Thus, when the vehicle turns right or left from a stopped state, pedal effort increment (ΔF−β) is set to relatively be small so that a smooth acceleration becomes possible.
