Power steering - Electric systems

1 'Electric power steering' ('EPS' or 'EPAS') uses an electric motor to

assist the driving|driver of a vehicle



1 By incorporating electronic stability control electric power steering

systems can instantly vary torque assist levels to aid the driver in

corrective maneuvers.



1 The first electric power steering system appeared on the Suzuki

Cervo in 1988. Today a number of manufacturers use electric power

steering.


Steering wheel

1 This can be through direct mechanical contact as in

recirculating ball or rack and pinion steering gears, without or with the

assistance of hydraulic power steering, HPS, or as in some modern production cars with the assistance

of computer controlled motors, known as Electric Power Steering


Steering wheel - Passenger cars

1 Power steering gives the driver an easier means by which the steering of a car can be accomplished. Modern power steering has

almost universally relied on a hydraulic system, although Electric Power Steering|

electrical systems are steadily replacing this technology. Mechanical power steering

systems (e.g., Studebaker, 1952) have been invented, but their weight and complexity

negate the benefits that they provide.
