1. A method comprising:

  • determining, by a processor of a mobile device, a first activity state indicative of a possible parking event associated with a vehicle, the first activity state based on a combination of a wireless communication disconnect event between the mobile device and the vehicle and an activity estimate from an activity classifier;

    determining, by the processor, a first confidence level associated with the first activity state;

    responsive to the first confidence level being a low confidence level based on the first activity state;

    obtaining, by the processor, a speed of the mobile device from at least one of a global navigation satellite system (GNSS) receiver or wireless access point (AP) signals;

    obtaining, by the processor, pedometer data from a digital pedometer of the mobile device;

    determining, by the processor, a second activity state indicative of a possible parking event associated with the vehicle, the second activity state based at least in part on the speed obtained from at least one of the GNSS receiver or wireless AP signals, the activity estimate and the pedometer data;

    determining, by the processor, a second confidence level associated with the second activity state; and

    responsive to the second confidence level being higher than the first confidence level, estimating, by the processor, a location of the vehicle using position data obtained from at least one of the GNSS receiver or the wireless AP signals.
