Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A method for estimating a location of a vehicle, the method comprising:
for a first trip of the vehicle along a first route:
receiving a first sensor dataset from a first sensor of a mobile user device;
receiving a second sensor dataset from a second sensor of the mobile user device;
determining a first set of vertical vehicular data based on the second sensor dataset, wherein determining the first set of vertical vehicular data comprises scaling the second sensor dataset based on a vehicular speed;
generating a mapping between the first sensor dataset and the first set of vertical vehicular data;

for a second trip of the vehicle along a second route;
collecting a third sensor dataset from the first sensor of the mobile user device;
collecting a fourth sensor dataset from the second sensor of the mobile user device;
detecting that the second route is the same as the first route;
in response to detecting that the second route is the same as the first route, adjusting a sampling rate of the first sensor; and
determining an estimated location of the vehicle based on the fourth sensor dataset and the mapping.
