Output control apparatus of internal combustion engine and clutch control device

An output control apparatus of an internal combustion engine (11) is provided in a vehicle (1) including a clutch (13) that permits and inhibits transmission of torque from the engine to a transmission (12) and an actuator (13a) for engaging the clutch when a driver's request for starting or creeping of the vehicle is detected. The apparatus controls the output torque of the engine so that the engine speed is kept lower than a permissible upper limit value and is kept equal to or higher than a permissible lower limit value over a predetermined period during engagement of the clutch. A clutch control device is also provided which determines an operation amount of the clutch based on clutch torque calculated based on the engine speed. The device includes a map that defines the relationship between the engine speed and the clutch torque, such that the clutch torque shifts from a torque region associated with a creeping operation of the vehicle to a torque region associated with a starting operation of the vehicle as the engine speed increases.
