METHOD FOR PREVENTING MOTOR REVERSE ROTATION, DURING REGENERATIVE BRAKING OF HEV

摘要

PURPOSE: A method for preventing back-rotation of a motor in the regenerative braking of a hybrid vehicle is provided to stably execute the shift in by preventing back-rotation of a motor in the regenerative braking. CONSTITUTION: A method for preventing back-rotation of a motor in the regenerative braking of a hybrid vehicle comprises the steps for executing the regenerative braking of a hybrid vehicle, sensing whether or not the shift to the low stage is executed in the regenerative braking, and supplementing the hydraulic pressure supplied to a clutch of an auto transmission. The hydraulic pressure supplementing step is executed by driving an external motor driven oil pump at 1000RPM or more.
