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

摘要

One method for remotely starting an engine of a vehicle includes notifying, from the vehicle, a remote user of the vehicle that a battery of the vehicle 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. Another method includes remotely starting the engine in response to a command, from the user, to start the engine for preconditioning the vehicle. This method assesses charge level of the battery following engine start and adjusts engine-on time and vehicle settings to prioritize battery charge maintenance versus preconditioning based on the charge level.
