Abstract

The invention provides an apparatus for controlling coasting operation in a hybrid vehicle, a system including the same and a method thereof. The apparatus includes: a coasting operation control modeentrance time point determination unit to determine a time point at which a subject vehicle enters a coasting operation control mode; a target vehicle speed reach time point calculation unit to calculate a target vehicle speed of the subject vehicle and a time point, at which the subject vehicle reaches the target vehicle speed, when the subject vehicle enters the coasting operation control mode;and a creep torque variation control unit to control creep torque of the subject vehicle using a difference between the target vehicle speed and a present vehicle speed of the subject vehicle.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefits from Korean Patent Application No. 10-2016-0158326 filed on November 25, 2016, which is incorporated herein by reference in its entirety. technical field [0003] The present disclosure relates to an apparatus for controlling a coasting operation of a hybrid vehicle and a method thereof, and more particularly, to a technique for effectively controlling the coasting operation. Background technique [0004] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0005] In order to improve fuel efficiency, vehicle manufacturers have introduced various control techniques for deceleration phases of vehicles based on inputs of road environment and deceleration by drivers, such as regenerative braking control and fuel cut control for deceleration phases of vehicles. Interest in devices and methods ...
