ABSTRACT:
A control method for suppressing a blow-up phenomenon during a power-on 2-3 upshift is provided. Disclosed steps include determining whether a predetermined shift compensation control entrance condition exists, determining whether a blow-up occurs if it is determined that the predetermined shift compensation control entrance condition exists, calculating an amount of the blow-up if it is determined that the blow-up occurs, performing a hydraulic duty compensation for an off-going friction element based on the amount of the blow-up, and performing an engine torque compensation based on a transmission output shaft rpm and a turbine torque. A system employing the method is also disclosed.
