ElEctric PowEr StEEring control ModulE (EPS)

HELLA has developed a steering control module for Electric Power Steering (EPS) which allows a demand-driven operation of the EPS to increase the fuel-efficiency of the vehicle. Thereby, the customer benefits from:

→ Compact design and easy integration → Readiness for ASIL D

HELLA provides an ECU for all types of Electronic Power Steering Systems that controls the electric motor power supply, supporting comfortable and fuel efficient driving. The ECU calculates the required steering torque necessary, based on incoming steering sensor signals, achieving a demand driven operation.

Apart from EPS ECUs the steering competence of HELLA is based on steering sensors, motor position sensors and DC/DC converters as well.

ADvAnTAgES → Demand-driven operation of the EPS electrical

motor improves fuel efficiency up to 0.4 l/100 km → Adaptive for a variety of OEM requirements → Flexibility with build-to-print manufacturing service → Maintenance-free and lightweight

(For example: no pump needed compared to hydraulic EPS)
