Delayed purely electrical operation of a hybrid vehicle

摘要

A vehicle and a method of controlling a vehicle include a controller configured to selectively operate an electric machine and an internal combustion engine to drive the vehicle in response to user instruction to delay the vehicle's purely electrical operation a state of charge of a drive battery that is electrically connected to the electric machine is generally kept at a target value within a predefined state of charge state. A vehicle includes a powertrain and control. The controller is designed to (i) operate the powertrain in a charge depleting mode and a charge sustaining mode, and (ii) in response to a user request to operate the powertrain in charge sustaining mode if the state of charge changes when the Request is within a predefined charge state range.
