Abstract
A throttle controller having a throttle control section is provided so as to eliminate any inconsistency in the degree of opening of the throttle at the time of mode switching, and to obtain a superior driving efficiency. In the driving mode, the throttle control section calculates the degree of opening of the throttle for generating a target driving force calculated based on a plurality of parameters including the degree of depression of the accelerator, and performs a driving-force control. In the manual mode, the throttle control section performs a control for driving the engine using a degree of opening of the throttle which one-to-one-corresponds to the degree of depression of the accelerator. When the mode is switched between the driving and manual modes, the throttle control section performs switching between the two control modes if the degree of depression of the accelerator is minimum or maximum.
