摘要： An embodiment method of controlling traveling of an electrified vehicle equipped with an electric motor as a power source includes determining whether it is possible to enter a variable control function. The variable control function includes a function of variably controlling a coasting torque level using a regenerative braking force. In response to a determination that it is not possible to enter the variable control function, a cause of an inability to enter the variable control function is determined and control is performed in a manner that corresponds to a determination that it is possible to enter the variable control function or the determination of the cause of the inability to enter the variable control function in response to the determination that it is not possible to enter the variable control function.

摘要： A hybrid vehicle and a control method are provided. The method of controlling a hybrid vehicle including a motor, an engine, and an engine clutch disposed between the motor and the engine includes determining whether to enter a first mode in which both the engine and the motor operate without engagement of the engine clutch, based on at least a first condition related to an accelerator pedal and a second condition related to a required torque condition, determining torque of the motor in consideration of at least required torque upon determining entry into the first mode, and determining an operating point of the engine based on engine generation power to be supplied to the motor with power of the engine.

摘要： A method of controlling a brake lamp of a vehicle including an electric motor as a power source includes determining whether gear shifting is required and whether there is a forward section with a suddenly changing slope when regenerative braking is performed through the electric motor without manipulation of an accelerator pedal or a brake pedal, delaying the gear shifting until the gear shifting exceeds a gear-shifting limit when the gear shifting is required and when there is the forward section with the suddenly changing slope, calculating acceleration based on regenerative braking torque while the gear shifting is delayed, and controlling the brake lamp based on the calculated acceleration.

摘要： A hybrid electric vehicle and a driving mode control method are provided to prevent overheating of an electric motor. The hybrid electric vehicle is chargeable using external power. The method includes collecting forward driving information when a state of charge of a battery is equal to or greater than a first value and calculating a driving load for each section based on the forward driving information. A risk of overheating of an electric motor is predicted using the calculated driving load. The vehicle is driven in a first mode using drive power of an engine in a section in which the predicted risk of overheating is greater than a second value and in a second mode using drive power of the electric motor in a section in which the predicted risk of overheating is equal to or less than a preset value.

摘要： A hybrid electric vehicle and a braking control method thereof are provided. The method includes determining, by a first controller, a total braking amount corresponding to a brake pedal manipulation amount and transmitting a regenerative braking request corresponding to at least a portion of the total braking amount to a second controller. A state of a regenerative braking system having a motor and a battery is determined and a regenerative braking execution amount is calculated by selectively using a first torque corresponding to a torque command transmitted to a third controller to operate the motor based on the regenerative braking request or a second torque measured by the third controller based on the determined state. A braking force of a frictional brake is determined based on the calculated regenerative braking execution amount and the total braking amount.

摘要： A hybrid electric vehicle is capable of maximizing energy efficiency during platooning, and a platooning control method is carried out on the hybrid electric vehicle. The method includes acquiring acceleration information and deceleration information of each of a plurality of vehicles traveling in a platoon form for platooning so as to realize a pulse-and-gliding traveling mode, determining a traveling order of the vehicles during the platooning based on the acceleration information, and determining a time at which to start a glide phase of a following vehicle in the determined traveling order based on a time at which a glide phase of a preceding vehicle starts using the acceleration information and the deceleration information.
