POWER STEERING SYSTEM


  1. OUTLINE


    1. A vehicle speed sensing type Electric Power Steering (EPS) system is used.

    2. This system generates assist torque using a power steering motor and a reduction mechanism that are mounted on the steering column assembly to assist the driver's steering.

    3. A rack and pinion type steering gear assembly is used.

  3. MAIN FEATURES


    1. The EPS system has the following features:


      1. The EPS system activates the power steering motor only when the driver turns the steering wheel. This reduces the energy consumption in a straight driving situation, resulting in excellent fuel economy.

      2. The torque sensor, power steering motor and reduction mechanism are integrated into the steering column assembly, giving a simple and compact structure.

      3. Unlike the conventional hydraulic power steering system, this system excels in serviceability because it does not require pipes, vane pump, pulley and power steering fluid.
