Roadway drivability assessment for mapping and navigation

Abstract:

Described herein are techniques for generating and utilizing drivability maps. The techniques including a method comprising receiving a set of vehicle performance records including a first vehicle performance record comprising a vehicle location, a vehicle configuration, and traction control system information. The method further includes determining, from the set of vehicle performance records, a respective Coefficient of Friction (CoF) value for respective road segments including a first CoF value for a first road segment. The method further includes determining, from the set of vehicle performance records and the respective CoF values, a first CoF threshold for a first vehicle configuration. The method further includes generating a drivability map for the first vehicle configuration indicating different levels of drivability for different road segments based on the respective CoF values for respective road segments and the first CoF threshold for the first vehicle configuration.
