With a total of 3 patents to his name, Maruyama's work is recognized for its innovative approach to enhancing vehicle efficiency.
Latest Patents
One of Maruyama's latest patents is a vehicle regenerative speed control device designed to suppress undershooting. This device ensures that the actual transmission input rotational speed does not fall below a lower-limit rotational speed when there is a request to decrease the regeneration amount during regenerative speed control. The device includes a controller that facilitates regenerative speed control by downshifting a continuously variable transmission to a low gear ratio, thereby increasing the rotational speed of the transmission input shaft connected to a motor generator during deceleration.
Another patent by Maruyama also focuses on a vehicle regenerative speed control device. This invention includes a controller that performs regenerative speed control for downshifting a belt-type continuously variable transmission to the low gear ratio side. It increases the rotational speed of the transmission input shaft connected to a motor generator when there is a request for an increase in the regeneration amount while decelerating. The controller imposes limitations on the Pri end command rotational speed change rate during the transition from regenerative braking to hydraulic braking.
