Abstract

A method of operating a vehicle having an electric drive is provided. The method includes defining a first zone and a second zone. The first zone has an associated first characteristic and the second zone has an associated second characteristic that differs from the first characteristic. The method further includes switching an operating mode of a vehicle from a first operating mode in the first zone to a second operating mode in the second zone in response to the vehicle translating from the first zone to the second zone. Associated vehicles and systems are provided also.

Claims

1. A system having information correlating an amount of energy used by a vehicle to an amount of fuel consumed by the vehicle or an amount of emissions emitted by the vehicle, comprising:

a controller operable to determine at least one of a saved amount of fuel or a reduced amount of emissions; and

a sensor operable to measure an amount of energy supplied by an energy storage device and to communicate information about that amount to the controller, wherein

the controller determines the saved amount of fuel or the reduced amount of emissions based on the amount of the energy supplied by the energy storage device.

2. The system as defined in claim 1, wherein at least a portion of the energy supplied by the energy storage device was provided to the energy storage device by regenerative braking of the vehicle.

3. The system as defined in claim 1, wherein the correlating information refers to an engine only propelled vehicle that consumes fuel and emits emissions, so that the amount of fuel saved or emissions reduced is an amount referring to the instant vehicle relative to the engine only propelled vehicle.

4. The system as defined in claim 1, wherein comprising a display screen secured to the vehicle that displays the amount of fuel consumed by the vehicle or an amount of emissions emitted by the vehicle.
