PROBLEM TO BE SOLVED: To provide an accelerator pedal control device of a vehicle capable of reducing a burden and a discomfort of an occupant, by setting an accelerator pedal reaction characteristic of taking into consideration a joint viscoelastic characteristic of a human being.SOLUTION: An accelerator pedal control device comprises a reaction setting part 22 for setting reaction F corresponding to a stepping-in quantity S of an accelerator pedal 3 and a stepping-in speed sensor 5 for detecting a stepping-in speed V of the accelerator pedal 3, and the reaction setting part 22 comprises a stepping-in quantity shaft of the accelerator pedal 3, a stepping-in speed shaft of the accelerator pedal 3 and a three-dimensional map M regulated by three axes with a reaction shaft, and this three-dimensional map M sets a reaction characteristic so that the reaction F becomes smaller than when the stepping-in speed V is slow when the stepping-in speed V detected by the stepping-in speed sensor 5 is fast. Thus, the reaction characteristic corresponding to the stepping-in speed V of the accelerator pedal can be set in the same tendency as a joint viscoelastic characteristic of the human being, and a perception reaction characteristic of an occupant can be improved.
【課題】人間の関節粘弾性特性を考慮したアクセルペダル反力特性を設定することにより、乗員の負担と違和感を軽減することができる車両のアクセルペダル制御装置を提供する。【解決手段】アクセルペダル3の踏込量Sに応じた反力Fを設定する反力設定部22と、アクセルペダル3の踏込速度Vを検出する踏込速度センサ5とを備え、反力設定部22が、アクセルペダル3の踏込量軸と、アクセルペダル3の踏込速度軸と、反力軸との3軸によって規定される三次元マップMを有し、この三次元マップMは、踏込速度センサ5によって検出された踏込速度Vが速いとき、踏込速度Vが遅いときに比べて反力Fが小さくなるように反力特性を設定している。これにより、アクセルペダルの踏込速度Vに応じた反力特性を人間の関節粘弾性特性と同様の傾向に設定することができ、乗員の知覚反力特性を改善することができる。【選択図】 図1
