Abstract
Location determination is facilitated based on motion data accumulated at a vehicle in cases in which a beacon is not available. One method includes receiving, by a first device, first information about a vehicle indicative of a position and a direction of the vehicle. The position is measured by the vehicle based on a measured angular rotation rate and radius of a wheel of the vehicle and the direction of the vehicle is measured by the vehicle based on a measured amount of a turn radius of a steering wheel device of the vehicle. The method also includes determining a previously determined location of the vehicle. The method also includes generating second information about a location of the first device based on the previously determined location of the vehicle and the first information. Error estimates for the location and/or tuning bias for sensors at the vehicle can also be determined.
