Abstract
A clutch control unit includes a clutch motor controller that controls a clutch motor. The clutch motor controller has a target clutch motor current computing unit that computes a target clutch motor current for adjusting torque of the clutch motor to be torque corresponding to an operating state of the vehicle, and a motor driving and braking selection unit that selects a motor driving mode in which the clutch motor is driven by applying feedback control on an output of the clutch motor or a motor braking mode in which the clutch motor is braked by short-circuiting the clutch motor according to a difference between the target clutch motor current and an actually detected clutch motor current. It thus becomes possible to provide a control system of a transmission that engages a clutch by a motor braking force in a manner that suits the running state of the vehicle.
