Abstract

A method of controlling a mild hybrid starter & generator (MHSG) of a mild hybrid electric vehicle may include: detecting data for controlling the MHSG; determining a target boost pressure based on the data; comparing a difference value between the target boost pressure and an intake pressure with a predetermined value; determining a target torque of the MHSG when the difference value between thetarget boost pressure and the intake pressure is equal to or greater than the predetermined value; and controlling the MHSG to generate the target torque of the MHSG.

Description

[0001] Cross References to Related Applications [0002] This application is based upon and claims the benefit of priority from Korean Patent Application No. 10-2016-0169853 filed with the Korean Intellectual Property Office on December 13, 2017, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates to methods and apparatus for controlling an MHSG of a mild hybrid electric vehicle. More particularly, the present invention relates to a method and apparatus for controlling an MHSG of a mild hybrid electric vehicle capable of improving acceleration feel. Background technique [0004] As is generally known in the art, hybrid electric vehicles use an engine and battery power together. Hybrid electric vehicles effectively combine the torque of an internal combustion engine and the torque of an electric motor. [0005] According to the power distribution ratio between the engine and the electric motor, ...
