Nexteer Automotive’s Rack Assist EPS (REPS) is designed for heavier vehicles to handle higher front-axle loads and optimize packaging space. These systems are capable of steering midsized vehicles, all the way up to Heavy Duty Trucks. System electronics are integrated with the steering rack.
The electronics for both systems are designed to withstand the high temperatures and environmental exposure, typical outside the driver compartment. In addition to saving valuable space inside the content-rich engine compartments, the unitized motor controllers for both PEPS and REPS are easily fitted to different vehicle platforms, reduce assembly costs, and increase performance integrity compared to systems employing remote electronic controls. Nexteer has been in production with Rack EPS since 2010.
