Accelerator reaction force control apparatus

An accelerator reaction force control apparatus comprising:

• an accelerator position detecting device that detects an accelerator position;
• a reaction force varying device that varies a reaction force of the accelerator so as to increase a reaction force of the accelerator by a prescribed increase amount with respect to a base reaction force when the accelerator position is equal to or larger than an accelerator position threshold value;
• and
• a threshold value setting device that sets the accelerator position threshold value based on at least one of a vehicle operating state and an engine operating state related to a fuel consumption rate,
• the reaction force varying device being further configured to vary a reaction force increase rate at which the reaction force of the accelerator is increased by the prescribed increase amount beyond the base reaction force, the reaction force increase rate including a first increase rate that is used during a first reaction force increase period of the increase of the reaction force and a second increase rate that is used during a second reaction force increase period of the increase of the reaction force, with the second reaction force increase period being subsequent to the first reaction force increase period, the second increase rate being larger during the second reaction force increase period than during the first reaction force increase period.
