Vehicles can end up in unplanned visits to workshops due to the driver not checking the vehicle status before using it in traffic. There are many factors not only caused by the environment but also due to the lack of tools that simplify or reminds about beforehand inspections. The purpose of this project was to introduce a smart-phone application that can display the health state (or related parameters) of a vehicle in a brief way and indicate if a part or function of the truck is not working properly. There are six functions in the application. Function status and function fault codes can display information about vehicles by giving two-dimensional plots about vehicle data, while function VSR displays some information in the form of text. Also, the user can submit their feedback through function comment. Function position is designed to give the users specific perspectives on an imported map based on their different user identity. Function check reminds about inspections that must be made before setting out on a driving mission. The application allows bus drivers and managers to continuously monitor different vehicle parameters with a statistical summary over time, as well as providing a method for following-up that drivers perform basic checks on the vehicle before it is taken into traffic.
