Development of a prototype dashboard for wheeled passenger transport

Abstract

The development of wheeled passenger transport is associated with the need to use many components from various manufacturers. All these components have parameters that should be displayed on the dashboard. In the modern world, the dashboard is the "face" of the vehicle. It should give the driver a complete picture of the vehicle condition. The information shown on the screen should be understandable and not misleading for the user, regardless of the level of his training. World trends show that the analog dashboard is being replaced by fully digital (graphical) ones. When the graphics is added, the software becomes considerably more complicated. In order to reduce the complexity of its development and to design it in parallel, a modular approach is used. For the dashboard, four software modules can be distinguished: drivers for working with the hardware, operating system, top layer software, and a graphical user interface. Modern dashboards use processors with operating systems based on Embedded Linux due to the fact that there are many ready-made drivers for the hardware for this operating system. To accelerate software development, Europian manufacturers use ready-made frameworks for working with graphics, for example, the cross-platform Qt framework. The article presents the results of the development of a prototype dashboard for wheeled passenger vehicles. The device components and necessary functionality of the product for mass production is determined.
