Investigation for the development of a new electric control unit for customized trucks

Abstract: Customized truck is a relevant and high-profit part of Scania’s market. Nowadaysdesigners do not have a self-developed electric control unit for introducing non-standardfunctionality. This thesis is intended to investigate the specification of a new system andan approach to implement it in current truck’s electrical system. The adopted methodsin this research are systems analysis, functional specification, HW & SW research andcomparison and validation test of prototype system. The results obtained in this researchinclude the potential functions and corresponding requirement specification, 5 types ofhardware alternatives and 2 recommended software platform. Their feasibility is verifiedby a prototype system with 2 typical functions, control the motor of inward sliding doorand combine the communication of different system. 3 recommended schemes and 2 directionsfor future research are given in the end. Based on investigation results, developersare able to know new system’s specification preliminarily, understand the architectural requirementsand suitable tools and materials for implementation. This research will helpto improve Scania’s truck’s electrical system and product manufacturing in the future.
