摘要： A hybrid electric vehicle (HEV) that can perform more efficient regenerative braking and a method of regenerative braking control for the same are disclosed. The method of regenerative braking control includes determining a total braking amount when a braking request is generated in a HEV including a first motor connected to an engine, a second motor directly connected to an input side of a transmission, and an engine clutch having a first end connected to the first motor and a second end connected to the second motor. The method also includes charging a battery using regenerative braking of the first motor when the engine clutch has been engaged in consideration of at least the total braking amount and charge power by regenerative braking of the second motor is less than charge limit power of the battery.

摘要： A shift control method for a hybrid vehicle includes: determining whether a request for a kick-down shift has been made; identifying predetermined input torque increase conditions when the kick-down shift request is made; comparing a predetermined input torque increase amount with a predetermined reference value when all of the input torque increase conditions are satisfied; and controlling a driving motor or an auxiliary motor to additionally output the input torque increase amount, based on the result of comparing the input torque increase amount with the reference value.

摘要： A hybrid electric vehicle and a method of driving control for same, which more effectively increases an amount of regenerative braking during deceleration and allows a rapid restart. A method for controlling a hybrid electric vehicle, including a step-variable transmission according to an embodiment of the present disclosure, may include an operation of prohibiting shifting when a preconfigured deceleration braking condition is satisfied. The method may further include an operation of slip-controlling an engine clutch disposed between an engine and a driving motor when an acceleration pedal is operated before a car stop holding time, in which the deceleration braking condition is maintained, exceeds a preconfigured reference time.
