ERL

Occuzone comfort scores are generated by ERL, LLC, which is a software and engineering services firm that provides seat design and evaluation services to the automotive industry. These services were developed over the past 18 years, working in conjunction with a global OEM and based upon research at Michigan State University. ERL seat designs are developed in CAD-integrated software, using an optimization algorithm and patented human body models to calculate seat patches at loaded and contact points on the STO surface. Seat evaluation uses the same software, but adds a measurement of seat stiffness and the scanned surface of the seat to constrain the optimization algorithm. The result, in both cases, is a Comfort Score that correlates highly (r=0.8) with ride data from drivers. ERL's proprietary software is the only seat design software in the world and represents a major advance in the state of the art in seat design and evaluation.

ERL replaces the current physical iterations in the seat development process with virtual iterations in the optimization software. Thus, ERL minimizes development costs at the OEM and supplier through a closed-loop design and development process that develops the design or evaluates the design with a comparison protocol, using a benchmark as a competitive baseline.
