Abstract
A throttle control apparatus includes an electrical drive unit for electrically driving a throttle of an internal combustion engine and a mechanical drive unit for driving the throttle through the operation of an accelerator by a driver. In the case where an abnormality is generated in the electrical drive unit, the driving of the throttle by the electrical drive unit is interrupted and the throttle is thereinstead driven by the mechanical drive unit. The mechanical drive unit is provided with a throttle opening angle control member. The throttle control apparatus further includes a torque control unit for suppressing an increase in output torque of the internal combustion engine in the case where a throttle opening angle is increased in the direction of an opening angle set by the throttle opening angle control member when the driving of the throttle by the electrical drive unit is interrupted.
