hydraulic power steering systems for cars augment steering effort via an actuator, a hydraulic cylinder that is part of a servo system. these systems have a direct mechanical connection between the steering wheel and the linkage that steers the wheels. this means that power-steering system failure (to augment effort) still permits the vehicle to be steered using manual effort alone.









































electric power steering systems use electric motors to provide the assistance instead of hydraulic systems. as with hydraulic types, power to the actuator (motor, in this case) is controlled by the rest of the power-steering system.
power steering
a hydraulic power steering (hps) uses hydraulic pressure supplied by an engine-driven pump to assist the motion of turning the steering wheel. electric power steering (eps) is more efficient than hydraulic power steering, since the electric power steering motor only needs to provide assistance when the steering wheel is turned, whereas the hydraulic pump must run constantly. in eps, the amount of assistance is easily tunable to the vehicle type, road speed, and even driver preference. an added benefit is the elimination of environmental hazard posed by leakage and disposal of hydraulic power steering fluid. in addition, electrical assistance is not lost when the engine fails or stalls, whereas hydraulic assistance stops working if the engine stops, making the steering doubly heavy as the driver must now turn not only the very heavy steering—without any help—but also the power-assistance system itself.
