EPSElectric Power Steering System
A compact electric steering platform tuned for precise road feel, efficient packaging, and integration with intelligent driving functions.
Standards
- ISO 26262 development path
- ASIL-oriented design
- AUTOSAR compatible
System overview
ATI EPS replaces hydraulic assistance with a software-defined mechatronic platform that reduces parasitic energy loss, frees packaging space, and gives OEM teams a repeatable calibration path. The system connects steering torque, vehicle speed, diagnostics, and ADAS requests so the same platform can serve daily comfort, high-speed stability, lane-centering support, and future steer-by-wire evolution.
Modular steering calibration for each vehicle class and tire package
Lower energy loss and cleaner packaging compared with hydraulic assistance
Native integration with ADAS, lane support, and vehicle motion control
Diagnostic-ready ECU architecture for production and service workflows
Technical profile
Capabilities and technical values are program-dependent and must be confirmed against the applicable OEM requirements, vehicle architecture and validation plan.
Problems it solves
- Solves inconsistent steering feel across trims by separating base hardware from calibration logic.
- Reduces hydraulic maintenance, leakage risk, and idle energy consumption in compact engine bays.
- Improves ADAS readiness by exposing predictable steering actuation, diagnostics, and safety monitoring.
Typical applications
- Passenger vehicles that need light low-speed steering and stable highway feedback.
- EV and hybrid platforms where energy efficiency and compact packaging are critical.
- ADAS-enabled steering programs requiring repeatable lane-support and assist behavior.
Technical profile
