Abstract

A method for controlling a hybrid vehicle may include detecting, in a controller, a circumstance that a vehicle is rapidly decelerated and then rapidly accelerated; confirming that a transmission clutch slipped in the controller as a result of performing the detecting; reducing a driving torque and a motor speed while minimizing a hydraulic pressure of the transmission clutch in the controller, in the case that the transmission clutch has slipped as a result of performing the confirming; determining when the transmission clutch is available for synchronization in the controller while performing the reducing; and normalizing the hydraulic pressure of the transmission clutch and the driving torque in the controller, in the case that it is determined that the transmission clutch is available for synchronization as a result of performing the determining.

Dependent claims

A method for controlling a hybrid vehicle, comprising:

detecting, by a controller, a circumstance that the vehicle is decelerated and then accelerated;
confirming, by the controller, that a transmission clutch has slipped, in a case of detecting the circumstance that the vehicle is decelerated and then accelerated as a result of performing the detecting;
reducing, by the controller, a driving torque and a motor speed while minimizing a hydraulic pressure of the transmission clutch, when the transmission clutch has slipped as a result of performing the confirming;
determining, by the controller, when the transmission clutch is available for synchronization while performing the reducing;
and
normalizing, by the controller, the hydraulic pressure of the transmission clutch and the driving torque, when the controller determines that the transmission clutch is available for the synchronization as a result of performing the determining.
