Latest Patents

One of Hase's latest patents is a vehicle transmission device. This device includes an input member coupled to a combustion engine and a rotary electric machine. It also features an output member connected to the wheels and a speed change mechanism with multiple friction engagement elements that provide various shift speeds. A control device is integrated to manage the speed change mechanism. During a regeneration downshift, while the rotary electric machine outputs regenerative torque, the control device sets a target increase capacity for the engagement-side element. This element's transfer torque capacity is increased over a predetermined period, while the disengagement-side element's capacity is decreased during an overlapping period. Another significant patent is a control device designed for managing a transmission. This device executes special speed change control when the speed change mechanism shifts to a lower speed ratio in a negative torque prediction state. The disengagement hydraulic pressure is lowered to allow the disengagement element to slip, maintaining this state throughout the speed change process.
