A common type of single-vehicle accident involves a vehicle entering a passageway with insufficient clearance. Variable vehicle dimensions, e.g., oversized trucks, automobiles with roof-mounted bicycles, etc. pose a special challenge since the dimensions of the vehicle are non-standard for just the duration of the trip. Little is done today to alert drivers of impending overhead collisions. Vehicles today utilize no more than clearance lights to signal their oversize dimensions to other vehicles. Navigation tools that account for low-ceiling passageways do not account for non-standard dimensions. This disclosure describes the use of cameras and LiDAR sensors to determine both the dimensions of the vehicle as well as oncoming passageways to warn the driver of potential overhead collisions. The dimensions of the vehicle are utilized along with dynamically updated maps to chart a route that is free of overhead obstacles.
