  • Patent number: 11506273
    Abstract: The present disclosure provides a cooling system including a decelerator and a cooling line provided in a gear housing to cool at least one of a gear and a lubricant. The cooling system is configured to control the temperature of the lubricant inside the decelerator by circulating a coolant through the cooling line. The decelerator includes a gear set including the gear and the lubricant for accommodating a backlash and a gear housing configured to surround the gear set for transmitting a torque output from an electric motor through the decelerator to a drive shaft and vehicle wheels.

  • Patent number: 9463800
    Abstract: A control method for a motor-driven vehicle includes comparing a motor output with a hill holding condition on an inclined road. A hill holding fail safe is performed through a brake cooperation control when the motor output is less than the hill holding condition. Since the brake cooperation control for the hill holding fail safe is implemented by an electronic parking brake (EPB) motor control on a hill holding condition, convenience is provided without difficulty of control according to an oil pressure.

  • Patent number: 9337756
    Abstract: The present disclosure provides an apparatus and a method for controlling a vibration of a driving motor in a vehicle by generating a vibration reduction torque using gains that correspond to a torque variation and an RPM of a driving motor. The method includes storing a gain table in which gain values that correspond to a torque variation and a revolution per minute (RPM) of a driving motor in a vehicle are recorded. The torque variation of the driving motor and the RPM of the driving motor are detected. The gain values are determined using the detected torque variation and RPM of the driving motor based on the gain table and reducing. In addition, a vibration of the driving motor is reduced based on the determined gain values.
