Abstract
A method for controlling operating mode of a vehicle having the electrically variable transmission includes requesting a shift in the operating mode of the transmission and determining if the shift in operating mode is desirable given vehicle conditions. If a shift is desirable then the system compares a timer value with a predetermined time value. The system instructs a shift in the operating mode of the transmission when the timer value is greater than or equal to the predetermined time value and instructs no shift in operating mode of the transmission when the timer value is less than the predetermined time value.
