Driving force control device

A driving force control device configured to causing a vehicle to travel by switching between a manual driving mode for controlling a driving force of the vehicle based on a manual-driving-mode driving force characteristic specifying a vehicle speed, an accelerator pedal position, and a longitudinal acceleration of the vehicle to be generated according to the accelerator pedal position as a target acceleration and an automated driving mode for controlling the driving force by automatic control without depending on an accelerator pedal operation by a driver, and configured to change, when the automated driving mode is shifted to the manual driving mode, the driving force from a driving force generated in the automated driving mode to a driving force generated in the manual driving mode, wherein

• when the automated driving mode is shifted to the manual driving mode,
• the driving force is controlled based on an override driving force characteristic specifying the target acceleration according to the vehicle speed, the accelerator pedal position, and a traveling resistance to the vehicle,
• the longitudinal acceleration at a fully closed accelerator pedal position is higher in the override driving force characteristic than in the manual-driving-mode driving force characteristic, and
• a graph representing a relation between the accelerator pedal position and the longitudinal acceleration in the override driving force characteristic and a graph representing a relation between the accelerator pedal position and the longitudinal acceleration in the manual-driving-mode driving force characteristic intersect at a specific accelerator pedal position different from a fully closed position and a fully opened position.
