  • Publication number: 20180099671
    Abstract: A 4 wheel drive vehicle removes sense of shift difference through an acceleration shift control mode, and the acceleration shift control mode transfers an independent other drive shaft input torque to a drive shaft not connected to a transmission with respect to a transmission input torque transferred to a drive shaft connected with the transmission, so that a vehicle acceleration in an actual shift section connecting between a fore-section and post-section of the shift can be maintained to be equal to the vehicle acceleration of the fore-section and post-section of the, thereby overcoming the transfer torque change, which is not overcome in a conventional slip control method, speed control method and time control method, when transferring a torque to the drive wheels in the actual shift section and realizing the shift quality without the sense of shift difference.

  • Patent number: 9709167
    Abstract: 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.
