Case Study: Land Rover achieves EPA emissions certification and cuts development time by 75% with MathWorks

Land Rover Vehicles Achieve EPA Certification with Embedded Code Generation and add2 Target Hardware

Land Rover faced a certification problem: emissions testing on a two‑wheel dynamometer requires two wheels to remain motionless, but its four‑wheel‑drive vehicles and electronic transfer case controller would not operate correctly when a prop shaft was removed. To avoid a costly, 12‑week custom controller build, Land Rover (with Jaguar and add2) turned to MathWorks tools — including Simulink, Embedded Coder (Simulink Coder/MATLAB Coder), and target support — and add2’s MICROGen hardware to emulate the transfer case controller and present valid CAN signals to the vehicle.

Using MathWorks software, the team modeled and simulated the transfer case in Simulink, generated production code with Embedded Coder, and deployed it to add2’s MICROGen target for on‑vehicle emulation and rapid iterations (some updates done in under 10 minutes). MathWorks’ solution enabled EPA and other emissions certifications, cut development time by about 75% (from roughly 12 weeks to under three), prevented control‑system faults during testing, and produced a reusable approach now applied across multiple Land Rover models.
