Method for controlling a hybrid vehicle and a recording medium thereof

A non-transitory computer-readable medium storing instructions that, when executed by a computing device including one or more processors, cause the computing device to perform a method of controlling a hybrid vehicle including a first motor powering one of front or rear wheels, and a second motor powering the other of the front or rear wheels, the method comprising:

• initiating a limp home mode based on determining that a failure in the second motor is detected while the hybrid vehicle is operating,
• determining whether a vehicle speed of the hybrid vehicle detected in the limp home mode exceeds a predetermined limit speed based on an engine start maintenance condition,
• controlling the hybrid vehicle in an electric vehicle (EV) mode, in which the hybrid vehicle is driven using only the first motor based on determining that the vehicle speed does not exceed the predetermined limit speed,
• controlling the hybrid vehicle in a hybrid electric vehicle (HEV) mode in which the hybrid vehicle is driven using the engine and the first motor based on determining that the vehicle speed exceeds the predetermined limit speed.

A hybrid vehicle comprising:

• a first motor configured to provide a driving force to one of front or rear wheels;
• a second motor configured to provide a driving force to the other of the front or rear wheels;
• and
• a controller configured to:
• initiate a limp-home mode upon determining that a failure in the second motor is detected while the hybrid vehicle is operating,
• determine whether a vehicle speed of the hybrid vehicle in the limp-home mode is less than or equal to a predetermined low-limit vehicle speed based on a condition for maintaining engine start,
• control the hybrid vehicle in an electric vehicle (EV) mode in which the hybrid vehicle is driven using only the first motor, when it is determined that the vehicle speed is less than or equal to the predetermined low-limit vehicle speed, and
• control the hybrid vehicle in a hybrid electric vehicle (HEV) mode in which the hybrid vehicle is driven using both the engine and the first motor, when it is determined that the vehicle speed exceeds the predetermined low-limit vehicle speed.
