Driver Initiated Remote Engine Start for Vehicle Preconditioning Having Battery Charge Maintenance Priority

Abstract

A method includes remotely starting an engine of a vehicle in response to a command, from a remote user of the vehicle, to start the engine for preconditioning the vehicle. The method assesses a charge level of a battery of the vehicle following engine start and adjusts engine-on time and vehicle settings to prioritize battery charge maintenance versus preconditioning based on the charge level. Another method for remotely starting the engine includes notifying, from the vehicle, the user that the battery has a charge level below a predetermined threshold. This method includes remotely starting the engine to charge the battery with energy from the engine upon receiving from the user a confirmation to start the engine.
