When you're driving slower, more power is provided thereby making it easier to turn and steer. Yet, for roughly half a century, this approach worked wonders for drivers around the world - until electric power steering (EPS) brought drivers into the 21st century.Įlectric power steering combines an electric motor with a computer and sensors to determine how much power to apply to the driver’s steering depending on the speed of the vehicle. These hydraulic systems exhibit a couple of unfavorable characteristics: they're complicated and they can negatively impact gas mileage. In hydraulic power steering systems, the steering relies on pressurized hydraulic fluid typically served by a mechanical pump powered by the automobile's engine. Learn what power steering is, how it works, and when to spot issues with your power steering system. Times have changed, though, and today’s drivers are far more likely to steer not with hydraulic power steering but instead with electric power steering. That all changed in 1951 with the debut of the Chrysler Imperial, the model that introduced hydraulic power steering to the world as “the miraculous new Hydraguide power steering.” In automotive history’s earlier days, steering even a fully-operational car required a good deal of effort. It's easy to take for granted but without it, maneuvering a vehicle would take some serious elbow grease. You can maneuver thousands of pounds of metal, rubber, wires, and technology without a second thought, all thanks to power steering.
