Abstract:
A hybrid motor vehicle is operated in a front-loaded electrical power mode. The motor vehicle includes a first, electrical based, propulsion system which is powered by electrical energy stored in a rechargeable battery, and a second, fuel-based propulsion system, which is powered by oxidation of a fuel. According to the method, the amount of electrical energy stored in the battery is measured, and a percentage of that measured level is selected. A distance D which the first propulsion system, operating singly, and using that stored energy, can propel the vehicle is determined. A hybrid cruising range, which is greater than the distance D is selected, and a controller controls the operation of the first and second propulsion systems, in accord with a profile, so as to power the vehicle such that when the vehicle has traveled through the hybrid cruising range, the selected percentage of electrical energy is depleted, and when the vehicle has traveled through lithe first 50% of the hybrid cruising range, over 50% of the selected percentage of electrical energy stored in the battery is depleted. Also disclosed is a controller for implementing the method.
