Electric Power Steering

Electric power steering (EPS) is a key technology for highly automated driving. The EPS has an electric motor which controls the vehicle steering. With an electric motor the EPS controls and assists vehicle steering and provides an optimal and enjoying steering feel. 

An Electronic Power Steering (EPS) system’s advantage over a hydraulic system is if the engine stalls, you will still have steering assist. This advantage can also be a disadvantage if the system should shut down while the engine is running you lose steering assist.


Electronic power steering systems eliminate the need for a pump, hoses and a drive belt connected to the engine using variable amounts of power. The configuration of an EPS system can allow the entire power assist system to be packaged on the rack and pinion steering gear or in the steering column.

The system does not drag on the engine from either a power steering pump or alternator because it will not provide assist until required by driver input. Also, there is no hydraulic fluid.
