System, method, and storage medium for controlling a hybrid electric vehicle

A system for controlling a hybrid electric vehicle, the system comprising:

• a first motor configured to provide torque to a rear wheel of a hybrid electric vehicle;
• a second motor configured to provide torque to a front wheel of the hybrid electric vehicle;
• an engine configured to provide torque to the front wheel of the hybrid electric vehicle;
• a battery configured to provide energy to the second motor;
• and
• a controller configured to:
• control the hybrid electric vehicle to four-wheel driving or front-wheel driving when a speed of the hybrid electric vehicle is greater than a predetermined speed value or a state of charge (SOC) of the battery is greater than a predetermined SOC value;
• and
• control the hybrid electric vehicle to rear-wheel driving when the speed of the hybrid electric vehicle is equal to or less than the predetermined speed value and the SOC of the battery is equal to or less than the predetermined SOC value.

A method for controlling a hybrid electric vehicle including a pair of front wheels and a pair of rear wheels, the method comprising:

• obtaining a speed of the hybrid electric vehicle and a state of charge (SOC) of a battery of the hybrid electric vehicle;
• determining whether a plurality of conditions is satisfied;
• controlling, based on a determination that a first condition among the plurality of conditions is satisfied, a first motor of the hybrid electric vehicle to provide torque to one of the pair of front wheels and the pair of rear wheels of the hybrid electric vehicle according to the first condition to charge the battery through a second motor of the hybrid electric vehicle;
• controlling, based on a determination that a second condition among the plurality of conditions is satisfied, the second motor to provide torque to the remaining pair of wheels, among the pair of front wheels and the pair of rear wheels, of the hybrid electric vehicle according to the second condition;
• and
• controlling, based on a determination that a third condition among the plurality of conditions is satisfied, an engine of the hybrid electric vehicle to provide torque to the remaining pair of wheels of the hybrid electric vehicle according to the third condition,
• wherein the first condition is that the speed of the hybrid electric vehicle is equal to or less than a predetermined speed value and the SOC of the battery is equal to or less than a predetermined SOC value,
• wherein the second condition is that the speed of the hybrid electric vehicle is equal to or less than the predetermined speed value and the SOC of the battery is greater than the predetermined SOC value, and
• wherein the third condition is that the speed of the hybrid electric vehicle is greater than the predetermined speed value.
