Chassis layout of an autonomous truck : A transportation concept for the mining industry

University essay from KTH/Fordonsdynamik

Abstract: Autonomous driving might increase safety and profitability of trucks in many applications. The mining industry, with its enclosed and controlled areas, is ideal for early implementation of autonomous solutions. The possibility of increased productivity, profitability and safety for the mining industry and the mining area as a ground for development could, through collaboration, result in many benefits for both mining companies and truck manufactures. Scania must investigate how these autonomous vehicles should be constructed. The project goal is thereby to develop a chassis layout concept for an autonomous truck. The concept should improve profitability and safety for transportation of materials within the mining industry while minimizing the introduction of new components to Scania. The chosen approach is based on the Ulrich & Eppinger method for product development including generation and selection of concepts. Product requirements were specified from identified customer needs. The generated concepts were evaluated against these requirements and comparisons were performed with weighted matrices. Some benefits of the final chassis layout concept are a higher load carrying capacity, more robust component placement and higher ground clearance. The vehicle concept would also be able to operate in underground mines with low roof clearance which could open new market segments for Scania. However, the concept requires development to gain higher performance on load carrying components in the chassis front. The suggested concept shows that Scania could build and deliver autonomous mining vehicles with optimized chassis layouts based on Scania’s existing components within a near future.
