Pinion-Assist Electric Power Steering (PEPS) expands the application range and flexibility compared to Column-Assist 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.
