Vehicle electrical systems distribute power and data amongst electrical subsystems and components enabling safe, efficient, and cost-effective vehicle operation. With its myriad of complexities and interdependencies on all connected sub-systems, the electrical system design process poses significant technical and logistical challenges to make it function reliably. SaberES Designer™ enables design teams to address these challenges by providing an integrated process for electrical system design from concept to manufacturing. SaberES Designer minimizes data entry, manages complex, system-wide design variants, enables concurrent engineering, maintains data integrity, and allows efficient exchange with 3D CAD systems.
