A vehicle regenerative speed control device is provided for suppressing undershooting, in which an actual transmission input rotational speed falls below a lower-limit rotational speed, when decreasing a transmission input rotational speed based on a request for a decrease in the regeneration amount during regenerative speed control. The vehicle regenerative speed control device includes a controller which performs a regenerative speed control for downshifting a continuously variable transmission to a low gear ratio side and increasing a rotational speed of a transmission input shaft to which a motor generator is connected when there is a request for an increase in the regeneration amount while decelerating.

Vehicle regenerative speed control device

A vehicle regenerative speed control device is provided that includes a controller which performs a regenerative speed control for downshifting a belt-type continuously variable transmission to the low gear ratio side and increasing a rotational speed of a transmission input shaft to which a motor generator is connected when there is a request for an increase in the regeneration amount while decelerating. The controller also imposes the limitation of staying within a Pri end command rotational speed change rate for the Pri end command rotational speed when performing a regenerative speed control for increasing the Pri end command rotational speed based on a braking operation in a brake switching region for switching from regenerative braking to hydraulic braking due to a decrease in vehicle speed.

A flow outlet structure for an automotive air conditioner which is equipped with a louver having a plurality of movable slats and a fluidic element to cyclically change the direction of flow laterally of the automobile as long as the angle of the slats of the louver are below a predetermined angle. When the slats of the louver takes an angular position greater than the predetermined angle, the flow of cool air in three diversified directions is provided.
