To provide an apparatus for learning of clutch transmission torque, capable of obtaining a learning value of a relationship between a clutch stroke and clutch transmission torque for producing a clutch torque map, with high accuracy.
In a vehicle stop state, torque produced in a drive wheel according to a gradient of a road surface is calculated. If an automatic clutch assumes a semi-connection state due to start operation of the vehicle, clutch transmission torque caused by engine torque is obtained from torque calculated on the basis of an output value of an acceleration sensor and torque produced in the drive wheel according to the gradient of the road surface, and a relationship between a clutch stroke position and the clutch transmission torque is acquired as a learning value. This operation is executed over an entire region of the clutch stroke of the automatic clutch, and the clutch torque map is produced from the acquired learning value.
