DRIVING FORCE CONTROL DEVICE

To provide a driving force control device that can suppress driving force from changing suddenly.SOLUTION: Provided is a driving force control device of a vehicle which can travel while switching between a manual driving mode in which driving force of the vehicle is controlled on the basis of driving force characteristics for the manual driving mode and an automatic driving mode in which the driving force is controlled by automatic control without depending on operation of an accelerator pedal by a driver. When making a transition from the automatic driving mode to the manual driving mode, the device controls driving force on the basis of driving force characteristics for override that specify target acceleration in accordance with a vehicle speed, an accelerator pedal position and travel resistance against the vehicle, so that longitudinal acceleration at a fully-closed accelerator pedal position becomes higher in the driving force characteristics for override than in the driving force characteristics for the manual driving mode, and so that graphs representing the relations between the respective accelerator pedal positions in the driving force characteristics for override and in the driving force characteristics for the manual driving mode and the longitudinal acceleration cross at a specific accelerator pedal position which is different from accelerator pedal positions which are fully closed and fully opened.SELECTED DRAWING: Figure 4 【課題】駆動力の急変を抑制することができる駆動力制御装置を提供すること。【解決手段】手動運転モード用駆動力特性に基づいて車両の駆動力を制御する手動運転モードと、運転者のアクセルペダル操作に依存せずに自動制御で駆動力を制御する自動運転モードとを切り替えて走行可能な車両の駆動力制御装置であって、自動運転モードから手動運転モードへ移行する場合に、車速、アクセルペダル位置、及び、車両に対する走行抵抗に応じて目標加速度を規定するオーバーライド用駆動力特性に基づいて駆動力を制御し、全閉のアクセルペダル位置における前後加速度が、手動運転モード用駆動力特性よりもオーバーライド用駆動力特性のほうが高く、且つ、オーバーライド用駆動力特性及び手動運転モード用駆動力特性のそれぞれのアクセルペダル位置と前後加速度との関係を表したグラフが、全閉及び全開とは異なる特定のアクセルペダル位置で交差する。【選択図】図４
