CONTROL SYSTEM OF HYBRID VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a control system of a hybrid vehicle capable of initiating shift control without occurrence of a delay time.SOLUTION: A control system of a hybrid vehicle in accordance with the present invention includes a continuously variable transmission coupled to an output shaft of an engine, clutches interposed between the continuously variable transmission and driving wheels, an electric motor coupled to the driving wheels, and an oil pump that is driven by the engine and feeds a hydraulic pressure to the continuously variable transmission and clutches. If the clutches are changed from an engaged state to a disengaged state during deceleration and regeneration during which a regenerative torque is applied to the driving wheels by the electric motor, the gear ratio of the continuously variable transmission is shifted to a minimum gear ratio or maximum gear ratio.
