SHIFT CONTROL METHOD AND SYSTEM FOR HYBRID VEHICLE

摘要

A shift control method and system for a hybrid vehicle are provided to increase the recovery rate of regenerative energy, improve the fuel efficiency, and minimize the loss of the fuel efficiency upon reaccelerating after braking. The method include: acquiring in real-time information regarding a transmission input speed during driving and sensing a brake pedal operation. In addition, whether a road driving situation or a driver tendency corresponds to a skip shift allowable condition is detected when the brake pedal operation is sensed. A target shift stage to which a skip shift of two or more stages is performed is selected from a current shift stage based on the transmission input speed in real-time, when the road driving situation or the driver tendency corresponds to the skip shift allowable condition. Then a transmission is operated to shift to the selected target shift stage.

1. A shift control method for a hybrid vehicle, comprising:
acquiring, by a controller, in real-time information regarding a transmission input speed while the vehicle is being driven, and sensing a brake pedal operation; detecting, by the controller, whether a road driving situation or a driver tendency corresponds to a skip shift allowable condition when the brake pedal operation is sensed; selecting, by the controller, a target shift stage to which a skip shift of two or more stages is performed from a current shift stage based on the transmission input speed in real-time, when the road driving situation or the driver tendency corresponds to the skip shift allowable condition; and operating, by the controller, a transmission to shift to the selected target shift stage.
