  • Publication number: 20240100960
    Abstract: A vehicle includes a battery, a first motor configured to provide a first wheel and a second wheel with a driving force, and a second motor configured to provide the first wheel and the second wheel with different rotational forces. The vehicle also includes a controller configured to output a first torque command and a second torque command, a first motor driver and a second motor driver configured to convert power output from the battery in response to, respectively, the first torque command for the first motor and the second torque command for the second motor. The controller is configured to determine a torque limit of the first motor based on a state of charge (SoC) of the battery and a rotational speed of the first motor and a torque limit of the second motor based on the SoC of the battery and a rotational speed of the second motor.

  • Patent number: 11801760
    Abstract: A method for controlling torque vectoring of an xEV includes detecting vehicle speed information using speed sensors mounted in the xEV, and estimating a vehicle speed of the xEV in driving based on the detected vehicle speed information, setting a state of the xEV based on the estimated vehicle speed, determining whether there is an intervention request based on the set state of the xEV, detecting a steering angle of the xEV when the intervention request is rejected, and when the detected steering angle of the xEV is within a predetermined reference angle range, determining the xEV as being in a first slip state in which the xEV slips in a longitudinal direction, and resetting the vehicle speed of the xEV through output of a torque vectoring (TV) motor mounted in the xEV.

  • Publication number: 20230182712
    Abstract: Disclosed herein is a method of controlling a hybrid electric vehicle in which a torque converter is disposed between a motor and a transmission for driving the hybrid electric vehicle comprises, by a control unit, determining a driver demand torque and an output speed of the torque converter based on vehicle driving information, determining a target input speed of the torque converter from the determined output speed of the torque converter based on preset characteristic information of the torque converter and information on the determined driver demand torque, determining the determined target input speed of the torque converter as a target engine starting speed, and performing control to start an engine using torque of the motor when an engine-on mode is determined, and controlling and engine speed to the determined target engine starting speed after startup.

  • Patent number: 11136045
    Abstract: A cooperative control method and apparatus for maintaining driving in response to engine clutch failure are provided. The cooperative control method includes monitoring refill temperature conditions of operating oil of an engine clutch and performing cooperative control between a radiator and an engine cooling water circulation pump based on change in temperature of the operating oil of the engine clutch. Additionally, the method includes determining whether the engine clutch is in a refill dangerous stage and turning off an engine to be turned off when the engine clutch is in the refill dangerous stage. Whether the temperature of the operating oil is mitigated is determined based on the refill temperature conditions, when the engine is turned off and oil refilling is performed when the temperature of the operating oil is not mitigated.
