Power Steering Systems

Electric Power Steering System Sensors and Power ICs Power Steering Systems Electronic Power Steering (EPS) systems are becoming prevalent in automotive systems and are quickly replacing hydraulic assist power steering. The move to EPS systems is driven by the necessity for improving overall fuel efficiency and reducing system cost in automobiles. EPS systems [...]

Ring Magnet Speed Sensing for Electronic Power Steering

figure 1 Typical EPS System Proper control of Electric Power Steering (EPS) systems requires both speed and direction information from the steering input shaft. This control will typically come from both high-resolution speed information and fairly coarse position information. A dual multi-pole ring magnet can be used with a matrix of Hall [...]
