EHPS
Electric-Hydraulic Power Steering
Introduction

EHPS adopts PMSM & ECU Powerpack to drive the hydraulic recirculating ball.

EHPS can set the power-assisted curve which changes with the vehicle speed, to solve the problem that HPS cannot balance both the lightness at low speed and steering stability in high speed.

Besides, the problem of poor fuel economy is also solved by separating the steering pump from the engine. 

Applied to Vehicle
  • Heavy Duty Truck
