Abstract
System and methods are provided for improving fuel economy of a hybrid vehicle. A hybrid vehicle may include an EV driving mode, where the motor alone powers the hybrid vehicle. However, use of such a driving mode may be limited to conditions involving low drive force and power requests due to motor and battery power specifications. In some circumstances, the conditions during which the motor can be used to power the hybrid vehicle can be expanded. Such conditions may include instances where the driver only seeks light accelerations for a short period of time. Such an expanded EV mode may be triggered when the hybrid vehicle is travelling a downhill grade.
