A Framework for Optimizing Wiring Harness of Automated Electric Vehicles

Abstract:

Autonomous driving， digitalization， and electromobility have greatly increased the number of functions in vehicles in recent years. This trend will continue in the coming years. An extension of functions is often associated with an increase in the quantity of wires. However， for energy-efficient and thus sustainable mobility， developers need to keep the vehicle weight as low as possible. Likewise， the minimization of costs must be strived for. For this purpose， an algorithm is necessary， which designs the wiring under the specification of component positions. We took into account various constraints with regard to packaging， temperature load， and ease of assembly aspects. In addition， the routing can be controlled by desired preferences， e.g. more wires along the center of the vehicle than on the outside in the direction of the vehicle's longitudinal axis. The specification of cable lengths， diameters as well as the exact routing are the results. Previous approaches usually consider only partial aspects， no 3D structure， and only a few number of constraints.
