Realization of superior steering feel and high output. Automotive Products DPA-EPS Dual Pinion Assist EPS

Objective of development

We have strived and had developed an EPS system which has, as compared to the conventional system, a superior steering feel with high efficiency and higher output.

Technical feature、superiority

Compared to the conventional EPS system, the DPA-EPS® system has one pinion on each side (steering side / assist side) and has the power assist mechanism placed away from the steering axis to damp vibrations from the motor or unpleasant inputs from road surfaces, which contributed to the realization of crisp steering feel.
The speed reducer can be set independently of the steering axis, making it possible to set the optimum reduction gear ratio and obtain efficient and high outputs.
