DEVICE FOR THE VEHICLE SPEED RECUPERATIVE CONTROL Russian patent published in 2018 - IPC F16H61/04 

FIELD: transportation.

SUBSTANCE: present invention is equipped with motor generator (4) and belt type continuously variable transmission (6). This FF hybrid vehicle is equipped with a hybrid control module (81), which, when there is a request to increase the recovery amount during the deceleration, performs regenerative speed control to reduce the continuously variable transmission (6) gear towards the low transmission ratio and increases the transmission input shaft rotation speed, to which the motor-generator (4) is connected. Hybrid control module (81) also imposes a constraint to remain within the command speed change rate Pri end for the command rotation speed Pri end when performing regenerative speed control to increase the command rotation speed Pri end based on the braking operation in the brake switching area to switch from regenerative braking to hydraulic braking due to vehicle speed reduction.

EFFECT: enabling prevention of the driver discomfort occurrence, which supports the constant inquiry operation after request of increase, when performing the regenerative speed control based on the request to increase the recovery value in the brake switching area due to the vehicle speed decrease during deceleration.
