Vehicle location in weak location signal scenarios

A computer readable storage medium having program code stored thereon, the program code including instructions that, when executed by a processor in a mobile device, cause the processor to execute a method comprising:

• detecting, with a mobile device in the vehicle while the vehicle is moving, an unavailability of a first location technology;
• subsequent to detecting the unavailability of the first location technology, measuring sensor data from one or more sensors of the mobile device;
• determining, while the first location technology is unavailable, that the vehicle is in a parked state;
• and
• subsequent to determining the vehicle is in the parked state, calculating the location of the mobile device using the sensor data, the location being a location of the mobile device at a first time corresponding to when the vehicle is identified as being parked.

A method of identifying a location of a vehicle, the method comprising:

• detecting, with a mobile device, an unavailability of a first location technology;
• determining that the vehicle is in a parked state, the first location technology being unavailable when the vehicle enters the parked state;
• subsequent to determining the vehicle is in the parked state, measuring sensor data from one or more sensors of the mobile device;
• detecting, with the mobile device, the availability of the first location technology after the first location technology is unavailable;
• determining a next known location after the first location technology became available;
• and
• calculating the location that the vehicle is parked by combining the sensor data with a next known location, the location being a location of the mobile device at a first time corresponding to when the vehicle is identified as being parked.

• determining that the vehicle is in a parked state, the first location technology being unavailable when the vehicle enters the parked state;
• calculating a first location estimate, the first location estimate based on a last known location before detecting the unavailability of the first location technology and first sensor data measured after the first location technology became unavailable;
• detecting, with the mobile device, the availability of the first location technology after determining that the vehicle is in a parked state;
• and
• calculating a second location estimate, the second location estimate based on a next known location after detecting the availability of the first location technology and second sensor data measured after the parked state determination.
