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.

Abstract: A control device of an automatic transmission includes a motor control portion to control an output of a motor that executes a control operation on a clutch control portion. The motor control portion includes a target motor current computation portion that computes a target motor current according to a desired driving state, a motor current detection portion that detects plural motor currents respectively corresponding to plural detection timings, a selection portion that selects a motor current corresponding to the desired driving state among the detected plural motor currents, and a motor driving portion that applies feedback control on an output of the motor according to a difference between the target motor current and the selected motor current. Hence, not only can the most suitable clutch control be applied for each gear-change interval at gear change, but also the comfortable feeling during the driving and the fuel efficiency can be enhanced.

Abstract: In a transmission type screen structured to have at least two layers, namely, a first layer having a lenticular lens and having black stripes on the viewer's side relative to the lenticular lens and a second layer adjacent to the first layer, which are disposed sequentially as viewed from the viewer's side, the focal distance of the lenticular lens of the first layer is so set that external light having been skewly incident from the viewer's side and having passed through the gaps between the black stripes of the first layer is reflected on the lens surface of the lenticular lens of the first layer to impinge on the black stripes, whereby the “waviness” due to the light reflected by the second layer can be suppressed more effectively.
