Latest Patents
One of Moriyama's latest patents is a control device designed for vehicles. This device includes an electronic control unit that performs lock-up engagement pressure control for acceleration. It manages the engagement pressure of the lock-up clutch when the vehicle's speed increases by raising the rotational speed of the internal combustion engine. The electronic control unit initiates engagement pressure increase control once the actual rotational speed meets or exceeds a reference rotational speed, which is lower than the target rotational speed of the engine.
Another significant patent is a control device and method for a speed change device. This invention involves two clutches engaged concurrently to establish various speeds. In the event of an abnormality, one clutch is designated as the abnormal-time engagement element, while the other is the abnormal-time slipping element. The hydraulic pressure supplied to the engagement element is set higher than that for the slipping element during concurrent engagement.
