LOW-POWER ACCESS AUTHENTICATION

摘要

An authentication-based multi-stage powering scheme is disclosed. An initial authentication stage can include low-power components to sense user initialization signal and authenticate the user. When the user is authenticated the vehicle system can be initialized and one or more subsequent sensing components can be powered up and activated. When the one or more subsequent sensing components receives further user information, such as user proximity to the vehicle, subsequent parts of the vehicle system can be powered up and activated to allow user access to the vehicle.
