Abstract
Official abstract text for this publication.
A method and system for controlling anti-jerk of a hybrid vehicle reduce shift vibration and shock by reverse phase controlling a drive motor during gear-shifting of a hybrid vehicle without a torque converter. The method includes determining whether a gear-shifting command is outputted from a transmission control unit of the hybrid vehicle; when it is determined that the gear-shifting command is outputted, confirming a gear-shifting range divided into at least three phases in accordance with the gear-shifting command; determining whether the corresponding divided gear-shifting range is an anti-jerk allowed gear-shifting range; and when it is determined that the corresponding gear-shifting range is the anti-jerk allowed gear-shifting range, reverse phase controlling a drive motor of the hybrid vehicle by a predetermined value in order to reduce or attenuate vibration and shock generated in the corresponding gear-shifting range.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of controlling anti-jerk of a hybrid vehicle without a torque converter, comprising: determining whether a gear-shifting command is outputted from a transmission control unit of the hybrid vehicle; confirming a gear-shifting range divided into at least three phases in accordance with the gear-shifting command, when it is determined that the gear-shifting command is outputted; determining whether the corresponding divided gear-shifting range is a…
