Claim 11:
12. A hybrid electric vehicle comprising:
an engine;
a transmission coupled to the engine;
a drive motor and an engine clutch mounted between the engine and the transmission, the engine clutch including a battery;
a vehicle computer system that includes a hybrid control unit; and
a non-transitory computer readable recording medium storing programs that, when executed by the vehicle computer system, causes the vehicle computer system to:
correct a virtual vehicle speed to a target limit speed when a vehicle speed is higher than the target limit speed, wherein the virtual vehicle speed is transmitted to the hybrid control unit;
correct a virtual APS value to a first APS value when the first APS value is smaller than a second APS value, wherein the first APS value corresponds to a constant-speed driving load set to achieve the target limit speed based on load conditions and the second APS value corresponds to the target limit speed;
determine to operate the vehicle in a first mode when an actual APS value and the virtual APS value are substantially the same and transition to a second mode when the actual APS value and the virtual APS value become different, wherein the first mode is a mode configured to sustain a state of charge (SOC) of the battery at the target limit speed and the second mode is a mode configured to deplete the SOC; and
determine a transmission gear position by applying the virtual vehicle speed and the virtual APS value to one of a first shifting pattern and a second shifting pattern, wherein the first shifting pattern corresponds to the first mode and the second shifting pattern corresponds to the second mode.
