In-vehicle location uncertainty management for passive start

摘要

Method and apparatus are disclosed for managing location uncertainty areas for a passive start system of a vehicle. An example vehicle includes antenna modules for determining signal strengths of communication with a mobile device. The example vehicle also includes a wireless module configured to, when the mobile device is in a location uncertainty area (LUA), determine first and second location predictors. The wireless module is also configured to enable passive start when the first and second location predictors both indicate the mobile device is inside the vehicle. The wireless module is further configured to disable passive start if the mobile device is outside the vehicle.
