Abstract

The invention relates to a system and a method of estimating available driving distance.A vehicle includes a powertrain having a battery-powered electric machine. The vehicle also includes a controller programmed to display, on a geographical map, at least one contour line indicating an available driving distance from a current location. The distance of the contour line from the current location is based on energy stored within the battery and predicted energy consumption due to driving along each of a plurality of possible routes originating from the current location. The predicted energy consumption is updated based on energy depletion events that occur during driving.

Description

technical field [0001] The present disclosure relates to a powertrain control system for a battery powered vehicle. Background technique [0002] The vehicle may be propelled by operation of an electric machine configured to receive power from an on-board battery. It is common for batteries to be charged by electricity from the utility grid or other off-board power sources. Where the battery is the only source of propulsion energy, total depletion of the battery can render the powertrain inoperable. The occurrence of such an event may require time consuming battery recharging. Contents of the invention [0003] In at least one embodiment, a vehicle includes a powertrain having a battery-powered electric machine. The vehicle also includes a controller configured to display on the map at least one contour line indicating an available travel distance from the current location. The available driving distance from the contour of the current location is based on the energy s...
