Abstract:
1. A method of increasing readiness of a crossover gear shift in an automatic transmission, the method comprising the steps of: attaining at least one of a snatch operation of a disengaging switching element and an increase of the transmission rotational speed gradient by: issuing a crossover gear shift switching command to the transmission; transmitting a set transmission rotational speed and a set motor torque from a transmission controller to a motor controller; actuating a motor fueling to increase fuel supplied to an engine and to increase motor output torque to the automatic transmission immediately after issuing the crossover gear shift switching command depending upon one of the set transmission rotational speed and the set motor torque; and adjusting engagement and disengagement of transmission clutches depending on the increase in fuel supplied to the engine or a resultant increase in the motor output torque to the transmission during the gear shift.
