1. A vehicle computing device comprising:
- a data storage medium; and
a processing circuit programmed to receive from the data storage medium, a vehicle characteristic associated with an autonomous host vehicle, receive historical data associated with the vehicle characteristic at a first road segment, determine a correction factor to apply to the vehicle characteristic based at least in part on the historical data, and apply the correction factor to the vehicle characteristic to operate the autonomous host vehicle in accordance with the historical data,wherein the correction factor is an amount of correction applied to adjust the vehicle characteristic to a nominal value and wherein the nominal value is crowd-sourced from vehicles other than the autonomous host vehicle, andwherein the correction factor is a non-linear function of a variance factor, wherein the variance factor is a difference between a magnitude of the vehicle characteristic and the nominal value.

Abstract
A vehicle computing device includes a data storage medium and a processing circuit. The processing circuit is programmed to receive from the data storage medium, a vehicle characteristic associated with an autonomous vehicle, receive historical data associated with the vehicle characteristic at a first road segment, determine a correction factor for the autonomous vehicle based at least in part on the historical data, and apply the correction factor to the vehicle characteristic to operate the autonomous vehicle in accordance with the historical data.

10. A method comprising:
-
receiving a vehicle characteristic associated with an autonomous host vehicle; receiving historical data of distributed vehicle characteristics; determining a nominal value from the historical data, wherein the nominal value is collected from other vehicles and is associated with a first road segment; determining a correction factor to apply to the vehicle characteristic based at least in part on the historical data, wherein the correction factor is a non-linear function of a variance factor, wherein the variance factor is a difference between a magnitude of the vehicle characteristic and the nominal value; and applying the correction factor to the vehicle characteristic to autonomously operate the autonomous vehicle in accordance with the historical data, wherein the correction factor is an amount of correction applied to adjust the vehicle characteristic to the nominal value. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
