DREAMS: Replacing rear-view mirrors in trucks with integrated digital systems to improve safety

Digital systems replacing conventional rear-view mirrors on trucks are expected to improve traffic safety. The purpose of this project was to create a scientific basis about usability and safety benefits of such systems. 

In the project, Stoneridge’s prototype of a digital rear-view mirror system mounted on a Scania truck served as a use case. The prototype includes cameras mounted close to the front corners of the truck cabin and in-vehicle monitors mounted in A-pillars showing livestream videos of the surroundings to truck drivers, corresponding to the conventional truck mirrors of Class II and IV.

The project has developed knowledge on how digital rear-view camera systems operate, if truck drivers find them useful and appealing, and to what extent they can improve traffic safety. It has further developed Stoneridge's prototype and increased its technical maturity as well as generated requirements that a rear-view mirror replacemnet system needs to fullfil. A novel methodology for evaluating safety and usability aspects has been developed and applied. It consists of three parts: controlled experiments at the test track AstaZero, field tests on public roads and real-life applications. The project has also identified how to expand the functionality of the prototype regarding driver support and automated driving. 

The project was funded by Fordonsstrategisk Forskning och Innovation (FFI) and carried out by Stoneridge Electronics, in cooperation with RISE Viktoria (former Viktoria Swedish ICT) and Scania. It ran from Jan 1, 2015 to Sep 30, 2017.
