Abstract
A method and system for controlling a mild hybrid vehicle are provided. The method includes determining whether a first battery that supplies an electric power to a starter-generator of the mild hybrid vehicle is degraded. The starter-generator and a starter that receives an electric power from the second battery that stores a voltage less than a voltage of the first battery is operated to start an engine within the vehicle when the first battery is degraded and the ambient air temperature of the engine exceeds a temperature reference value.
Claims16
A method for controlling a mild hybrid vehicle, comprising:
- determining, by a controller, whether a first battery that supplies an electric power to a starter-generator of the mild hybrid vehicle is degraded;
- and
- operating, by the controller, the starter-generator and a starter that receives an electric power from a second battery that stores a voltage less than a voltage of the first battery to start an engine within the vehicle when the first battery is degraded and an ambient air temperature of the engine exceeds a temperature reference value.
A system for controlling a mild hybrid vehicle, comprising:
- a memory configured to store program instructions;
- and
- a processor configured to execute the program instructions, the program instructions when executed configured to:
- determine whether a first battery that supplies an electric power to a starter-generator of the mild hybrid vehicle is degraded;
- and
- operate the starter-generator and a starter that receives an electric power from a second battery that stores a voltage less than a voltage of the first battery to start an engine within the vehicle when the first battery is degraded and an ambient air temperature of the engine exceeds a temperature reference value.
