|Electric Power Steering System with Variable Gear Ratio Development Objectives|
|Tokyo, July 2, 1997 --- The steering wheel is one of the most important tools in driving and as such should be little affected by external forces, yet faithfully respond to driver intentions.
In 1990 Honda introduced on the NSX its first electric power steering (EPS). This EPS system was developed to offer a steering feel worthy of a high performance mid-engined sports car.
The new electric power steering system we are introducing today is the culmination of our efforts in developing a high performance steering system meeting the particular demands of front wheel drive cars. This electric power system has a variable gear ratio, making it the first steering system of its type in the Japanese ordinary passenger car category.
This new steering system faithfully responds to driver expectations by providing just the necessary amount of steering assistance at all times. Being electrically powered, it also contributes toward reduced fuel consumption.
Construction and Technical Achievements* Description of the Electric Power Steering (EPS) System
The EPS provides steering assistance through a co-axial electric motor. A micro-processor determines according to vehicle speed and driving conditions the amount of steering assistance required at any given moment. The system provides a linear steering response proportional to steering wheel rotational speed, allowing for a very smooth and responsive steering feel.
