の駆動力制御装置。 A signal output means that includes a second throttle valve in the engine intake passage in addition to a normal first throttle valve that is interlocked with an accelerator pedal, and outputs a traction control request signal under predetermined operating conditions of the vehicle;
and a traction control means for controlling a second throttle valve in the fully closed direction in response to a traction control request signal, wherein when there is no traction control request signal, the second throttle valve is operated in the fully closed direction. Driving force control for a vehicle, characterized in that an initial opening control means is provided for controlling the opening and closing of the first throttle valve to follow the opening and closing of the first throttle valve within a range that does not affect the control of the intake air flow rate by the first throttle valve. Device.
