Pinion-Assist Electric Power Steering (PEPS) expands the application range and flexibility compared to Column EPS (CEPS). Our PEPS systems position the motor, controller and assist mechanism on the steering gear pinion shaft. Nexteer is currently the global market leader in Single Pinion-Assist EPS (SPEPS).

Single & Dual Pinion-Assist EPS
Single Pinion Assist EPS
SPEPS integrates the electric assist mechanism into the primary steering gear pinion shaft. Our SPEPS has a design range comparable to CEPS, but offers OEMs greater packaging flexibility, reduces OEM crossbeam strength/stiffness requirements and reduces torsional compliance of driving torque through the column and intermediate shaft assemblies.
Capacity: 130Nm assist torque (13.5kN rack load depending on c-factor)
- Typical vehicle applications: A-B-C segments
- Premium steering feel, driver comfort and superior handling rough the column and intermediate shaft assemblies.
- Modular design, scalable for global platforms
Dual Pinion EPS
Dual Pinion-Assist EPS (DPEPS) allows for the primary pinion to be optimized for vehicle dynamics and performance and a secondary pinion to be optimized for assist. It also provides additional design flexibility to locate the motor, controller and assist mechanism opposite the driver side of the vehicle under-hood.
Capacity: 130Nm assist torque (15kN rack load depending on c-factor)- Typical vehicle applications: C and D segments
- Premium steering feel, driver comfort and superior handling
- Modular design, scalable for global platforms
We also offer High Availability and High Output options for our SPEPS and DPEPS systems.
