mass-produced passenger cars appeared on the Suzuki Cervo in 1988. However, this simple method was not widely adopted by other automakers in the initial years due to the unnatural steering feel of the motor caused by the inertia at the time of rapid steering for danger avoidance in slower speed driving, as well as at the time of faster speed driving in which the electromagnetic clutch makes the steering force smaller, returning to the manual steering mode. In the year 1990, a direct full control system of a rack assist without a clutch was put into practical use in the Honda NSX (initially installed in automatics only). Since then, there has been a transition of trend from brush-attached motors to brushless motors in the rack type for ordinary vehicles and this method has become the mainstream.

response to variable-rate and variable-damping suspension systems, optimizing ride, handling, and steering for each vehicle. This new technological feature also gave engineers the ability to add new driver assistance features. This includes features such as lane assist, wind drift correction, etc. On Fiat group cars the amount of assistance can be regulated using a button named "CITY" that switches between two different assist curves, while most other EPS systems have variable assist. These give more assistance as the vehicle slows down, and less at faster speeds.

artificial steering feel, there is a separate hydraulically operated system that tries to turn the steering wheel back to centre position.

required to steer. This heavy effort is similar to that of an inoperative hydraulic steering assist system. Depending on the driving situation, driving skill and strength of the driver, steering assist loss may or may not lead to a crash. The difficulty of steering with inoperative power steering is compounded by the choice of

In this power steering system, the force steering the wheels comes from the car's high pressure hydraulic system and is always the same no matter what the road speed is. Turning the steering wheel moves the wheels simultaneously to a corresponding angle via a hydraulic cylinder. In order to give some

This system should not be confused with variable assist power steering, which varies steering assist torque, not steering ratios, nor with systems where the gear ratio is only varied as a function of steering angle. These last are more accurately called non-linear types (e.g. Direct-Steer offered by

Other electric power steering systems (including 4WS) later appeared on the Honda NSX after 1990, the Honda

A mechanical linkage between the steering wheel and the steering gear is retained in EPS. In the event of component failure or power failure that causes a failure to provide assistance, the mechanical linkage serves as a back-up. If EPS fails, the driver encounters a situation where heavy effort is

The steering booster is arranged so that should the booster fail, the steering will continue to work (although the wheel will feel heavier). Loss of power steering can significantly affect the handling of a vehicle. Each vehicle owner's manual gives instructions for inspection of fluid levels and

Since the hydraulic pumps are positive-displacement type, the flow rate they deliver is directly proportional to the speed of the engine. This means that at high engine speeds the steering would naturally operate faster than at low engine speeds. Because this would be undesirable, a restricting

A study in 1999 on the perceptual fidelity of steering force feedback, found that ordinary real-world truck and car drivers naturally expect an increase in feedback torque as speed increases, and for this reason early forms of power steering, which lacked such effect, were met with disapproval.

Other power steering systems (such as those in the largest off-road construction vehicles) have no direct mechanical connection to the steering linkage; they require electrical power. Systems of this kind, with no mechanical connection, are sometimes called

The first power steering system on a vehicle was apparently installed in 1876 by a man with the surname of Fitts, but little else is known about him. The next power steering system was put on a
Columbia 5-ton truck in 1903 where a separate
