Abstract
An efficiency information display for a vehicle includes an indicator arrangement having a visual display configured to provide vehicle efficiency information to an operator of the vehicle. The visual display includes a target vehicle efficiency. A control system, including at least one controller, is configured to receive at least one input related to current operating conditions of the vehicle. The control system provides at least one output to the indicator arrangement, such that the visual display indicates to the vehicle operator a current relative operating efficiency of the vehicle. The at least one input includes at least one of: information related to positive vehicle propulsion, information related to vehicle braking, or information related to vehicle creep torque cancellation. The control system is further configured to use the at least one input to determine the current relative operating efficiency of the vehicle independently from a fuel economy calculation for the vehicle.
