Abstract
A method for controlling a mild hybrid starter & generator (MHSG) for a torque assist and an air conditioner of a mild hybrid electric vehicle according to an exemplary embodiment of the present disclosure includes setting a minimum charge amount of a first battery of the mild hybrid electric vehicle based on an outdoor temperature of the vehicle, repeating charging and discharging of the first battery by operating the MHSG so that the charge amount of the first battery is maintained at the set minimum charge amount or more, and operating the MHSG to convert power from the first battery to a second battery.
Claims18
A method for controlling a mild hybrid starter and generator (MHSG) for a torque assist and an air conditioner of a mild hybrid electric vehicle, comprising:
- setting, by a controller, a minimum charge amount of a first battery of the mild hybrid electric vehicle based on an outdoor temperature of the vehicle;
- repeating, by the controller, charging and discharging of the first battery by operating the MHSG so that the charge amount of the first battery is maintained at the set minimum charge amount or more;
- and
- operating, by the controller, the MHSG to convert power from the first battery to a second battery.
An apparatus for controlling a mild hybrid starter & generator (MHSG) for a torque assist and an air conditioner of a mild hybrid electric vehicle, comprising:
- a first battery charge amount detecting sensor for detecting a charge amount of a first battery;
- an outdoor temperature sensor for detecting an outdoor temperature of the vehicle;
- and
- a controller for controlling the charge amount of the first battery and assisting an engine torque of the vehicle,
- wherein the controller is configured to:
- set a minimum charge amount of the first battery based on the outdoor temperature of the vehicle;
- operate the MHSG to repeatedly perform charging and discharging of the first battery so that the charge amount of the first battery is maintained at the set minimum charge amount or more;
- and
- operate the MHSG to convert power from the first battery to the second battery.
