A method of controlling an electrified vehicle may include determining a traveling environment level; determining a regenerative braking continuation range and a regenerative braking retention amount according to the traveling environment level when a preset deceleration condition is satisfied; and determining whether to maintain a regenerative braking amount as the regenerative braking retention amount based on whether a vehicle speed is included in the regenerative braking continuation range when the vehicle speed is lower than or equal to a preset regenerative braking termination vehicle speed.

Electrified vehicle and method for controlling a regenerative braking amount thereof

A control device for a hybrid electric vehicle includes an engine, a drive motor that drives the vehicle by assisting the engine, a battery that provides energy to the drive motor, and a processor. The processor may determine whether there is an attempt to fuel the vehicle. When it is determined that there is the attempt to fuel the vehicle, the processor may enter a refueling mode to maintain a state in which the engine is turned off, and when refueling is completed, the processor may release the refueling mode to turn on the engine according to an engine starting condition.

Control device for a hybrid electric vehicle and a control method thereof

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.

Shift control method for a hybrid vehicle

Proposed is a method of controlling a hybrid electric vehicle. In particular, the method includes: connecting a first motor directly connected with an engine with a second motor directly connected with an input end of a transmission, and determining whether to distribute an amount of error torque for the engine to the first motor or each of the first motor and the second motor on the basis of an efficiency of the first motor and an efficiency of the second motor.
