In today's society, technology that does not have integrated app control or digital control is considered outdated. In fact, the technological growth of new features and innovations has grown exponentially over the past 100 years. This rapid development makes it difficult for manufacturers of larger products and machinery to keep up, both due to time constraints and economic reasons.

The purpose of the thesis was to evaluate the benefits of digitalizing the electrical system in a vehicle, as well as developing a demorig with accompanying electrical architecture that demonstrates its feasibility. During the course of the work, it became clear that the major benefits of digitalizationwere a reduction in errors and malfunctions, while increasing flexibility and communication capabilities.

Finally, a fully functional solution was presented that was tailored to meet the requirements of Volvo Trucks, with the goal of being implemented in the next version of their Crew Cab. The logic behind the system was functionally tested in a demo rig that included all components from the cab. The project demonstrated a significant reduction in cabling with the ability to control components with high precision through pulse width modulation signals and transistors.
