  • A Diagnostic Machine Learning Model for Air Brake Systems in Commercial Vehicles [supporting dataset]
    Darbha, Swaroop ;
    Rajagopal, Kumbakonam
    2023-09-12 | JSON
    Safely introducing autonomy to trucks requires monitoring their brake systems continuously. Out-of-adjustment push rods and leakages in the air brake system are two major reasons for increased braking distances in trucks, resulting in safety violations. Air leakages can occur due to small cracks or loose/improperly fit couplings, which do not affec ...
