Abstract
Values may be tracked from wireless sensors of a vehicle that indicate distances between the mobile device and the sensors. When the signal strength values indicate the mobile device is within the vehicle, the device may be associated with a seating zone of the vehicle corresponding to the one of the sensors that provided signal strength values that peaked earliest in time. The mobile device may be determined to be within the vehicle by using a hypothesis test comparing a threshold signal strength value to the signal strength values.
