Claim 0:
1. A method for controlling a speed limit of a hybrid electric vehicle, the method comprising:
determining a virtual vehicle speed as being a lower one of an actual vehicle speed and a target limit speed, wherein the virtual vehicle speed is transmitted to a hybrid control unit;
determining a virtual accelerator position sensor (APS) value as being a larger one of a first APS value and 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;
operating the vehicle in a first mode when an actual APS value and the virtual APS value are substantially the same and transitioning to a second mode when the actual APS value and the virtual APS value become different, wherein the first mode is a mode for sustaining a state of charge (SOC) of a battery at the target limit speed and the second mode is a mode for depleting the SOC; and
determining a transmission gear position by applying the determined virtual vehicle speed and the determined 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.
