Electric Power Steering (EPS)

Column type EPS
Outline
  • The power-assist unit, controller and torque sensor are attached to the steering column.
  • This system is compact and easy to install on the vehicle.
  • Application not only on fixed-type steering columns but also on tilt-type columns, etc. is possible.
   
Pinion type EPS
Outline
  • The power-assist unit is attached to the pinion shaft of the steering gear.
  • The power-assist unit is located in the engine compartment, eliminating concern about passenger compartment noise and allowing the use of higher assist forces.
  • This steering system excels in handling characteristics, and application of a variable-ratio steering gear enables the use of compact motors.
   
Rack direct-drive type EPS
Outline
  • The rack and power-assist unit form a single unit.
  • This steering system is compact and easy to install on the vehicle.
  • Power-assist is provided directly to the rack, enabling low friction and inertia and an ideal steering feeling.
   
Electric variable-gear-ratio steering (E-VGR)  
Outline
  • This variable-gear-ratio steering system is able to adapt the steering gear ratio flexibly to vehicle speed.
  • The amount of steering wheel turning at low vehicle speeds is greatly reduced, making low-speed maneuvering easier. At high speeds, this system provides a gentle, stable response.
  • Vehicle response lag during lane changes is reduced, and the gear ratio changes in response to the road surface conditions, allowing easier steering wheel return.
   
Hydraulic-electric type power steering (H-EPS)
Outline
  • This energy-efficient hydraulic power steering system is driven by an electronically controlled electric motor and hydraulic pump.
  • The motor, pump, reservoir and controller compose a single unit, making installation on the vehicle easy and nearly eliminating the need for tube adjustments, etc. after installation.
  • The hydraulic pump, driven by a high-performance brushless motor, is energy efficient and has quick response.
