Automated driving and HMI design for city bus and truck with professional drivers

When vehicles are getting more and more automated driving functions, it is essential that a driver understands what the vehicle can and cannot do. HMI design for automated driving has lacked general guidelines until t he National Highway Traffic Safety Administration released their guidance for Level 2 and Level 3 Automated Driving concepts in August 2018. Once automated driving functions are started to be introduced to heavy vehicles such as city buses or trucks with professional drivers the role between the driver and the automated systems must be clear. This paper provides early results of the HMI design for a city bus and truck scenario s from TrustVehicle project . The shared autonomy approach and driver monitoring are utilised and HMI design support to keep the driver in the loop. Trust building with open feedback about automated driving performance including possible limitations are studied in the project.
