Abstract: A system for crowdsourcing reporting of road conditions from abnormal vehicle events. Abnormal vehicle events (such as sudden braking, sharp turns, evasive actions, pothole impact, etc.) can be detected and reported to a road condition monitoring system (RCMS). The RCMS can identify patterns in reported road conditions to generate advisory information or instructions for vehicles and users of vehicles. For example, suspected obstacles can be identified and used to instruct a driver or a vehicle to slow down gradually to avoid sudden braking and sharp turns. In some examples, a vehicle can have a camera that can upload an image of a suspected obstacle (e.g., a pothole) to allow the positive identification of a road problem. This provides the RCMS with more confidence to take a corrective action, such as an automated call to a road repair service.
