摘要: A method for controlling a vehicle including a continuously variable transmission includes determining, by a controller, whether a speed difference between a speed of a vehicle according to revolutions per minute (RPM) of a driving wheel of the vehicle and a speed of the vehicle according to revolutions per minute (RPM) of a towed wheel of the vehicle is equal to or greater than a speed reference value and reducing, by the controller, torque of an engine providing a driving force to a driving pulley of the continuously variable transmission when the difference in vehicle speed is equal to or greater than the speed reference value.

摘要: A method of controlling an electric oil pump (EOP) for a vehicle includes, if a current temperature of oil is lower than a reference temperature, determining whether an EOP RPM is lower than a minimum driving RPM, if the EOP RPM is lower than the minimum driving RPM, applying a first reduction rate for a first setting time and reducing a target line pressure and an instruction RPM of the EOP, if the EOP RPM is equal to or higher than the minimum driving RPM, determining whether vibration of the EOP RPM is generated above a reference vibration, and if the vibration is generated above the reference vibration, applying a second reduction rate for a second setting time and reducing the target line pressure or the instruction RPM of the EOP.

摘要: A powertrain for an electric vehicle includes: a planetary gear having a first rotating element, a second rotating element, and a third rotating element, wherein a first rotating element is connected to a first shaft and the second rotating element is connected to a second shaft; a first motor configured to selectively supply power to the first shaft at two or more gear ratios; a first shift assembly configured to transfer power of the first motor to the first shaft through one of two or more external engagement gear trains having different gear ratios; and a second motor configured to selectively supply power to the first shaft and the second shaft. The third shaft is fixedly disposed on a transmission housing, and any two shafts among the first, second and third shafts restrain each other.
