Electric Power Steering FAQs

Electric power steering has become a fixture on many new models of cars.  As with any new technology, particularly one that changes widely from the standard, this power steering technology has been surrounded by some controversy from the start.  Some welcome this change for its benefits, while others point to problems that have been discovered early on.  Here are some frequently asked questions about electric power steering that may help you make a decision on the car you plan on buying next.

How does electric power steering work?

Electric power steering works with an electric motor rather than a hydraulic pump.  When the driver turns the wheel, the motor detects the rate of turn.  A computer takes into consideration other factors such as the vehicle speed in order to determine what feedback the driver should feel in the steering wheel.

Why is electric power steering becoming more popular?

Automotive manufacturers have begun using EPS more and more in late model vehicles.  There are a few simple reasons.  First of all, electric power steering systems are less expensive for auto makers to build.  This means more profit at less cost.  Another reason for EPS popularity is that this system creates better overall fuel efficiency for a vehicle.

In vehicles in which power steering is controlled by a hydraulic pump, the pump constantly runs regardless of whether or not power steering is necessary.  Constant drag on the fuel system by this hydraulic pump harms a vehicle’s fuel performance.  Lastly, EPS systems cut down on the number of hoses and mechanisms under the hood, simplifying the manufacturing process.

Does EPS help me at all?

For many of the same reasons that auto makers have turned to electric power steering, this system has several benefits for a car owner.  Since the EPS vehicle needs no hoses or a hydraulic pump, it also requires no fluid.  You won’t need to worry about the power steering fluid level, or whether or not your vehicle has a leak.

A steering system that is operated by computer also has a benefit for you.  As with any computer system, the EPS system on your vehicle can be adjusted.  If you feel as though the power steering is somehow not working properly for you, an adjustment can be made with a computer, not a risky mechanical procedure.

Finally, the fuel economy of the EPS system makes it ideal for any car buyer.  Innovations that provide higher fuel efficiency are what drive car sales while at the same time making vehicle owners happy.

Are there problems with electric power steering?

There are still issues with EPS that require some ironing out.  Several auto manufacturers have issued recalls of their power steering issues after receiving numerous complaints.  Some drivers report that the power steering causes the car to veer while driving at high speeds.  Others have cited difficulty steering the vehicle and an occasional loss of steering ability.

Auto manufacturers are investigating the source of these problems and working to ensure safety and functionality.  While there are some issues with EPS, there is no arguing that this system is steadily growing to replace the traditional hydraulic power steering.
