Patent ID: 8527171

Claim:
A reaction force imparting system of a vehicle accelerator pedal, comprising: a running circumstance detection apparatus configured to detect two or more running circumstances of a vehicle; a reaction force generation apparatus configured to, depending on the running circumstance detected by the running circumstance detection apparatus, generate reaction force for an accelerator pedal in a returning direction thereof based on a predetermined reaction force target value, wherein the accelerator pedal is operated by tread force of a driver, and the predetermined reaction force target value is differentiated according to each of the running circumstances; and a reaction force correction apparatus configured to make correction to reduce the reaction force currently generated by the reaction force generation apparatus when it is predicted that the predetermined reaction force target value is increased by a change of a running circumstance detected by the running circumstance detection apparatus, and a difference between the predetermined reaction force target value corresponding to the running circumstance after the change and the reaction force currently generated by the reaction force generation apparatus is less than a predetermined difference.
