ELECTRICAL POWER STEERING

摘要

It's no secret that vehicle manufacturers are under the gun these days to make their vehicles more fuel efficient. Federal mandates and consumer demand for more fuel-efficient vehicles are changing the way automotive engineers look at vehicle design. One way they are achieving higher miles per gallon is by eliminating accessory loads from the engine. A major contributor to this accessory load is the hydraulic power steering pump. Electrical power steering (EPS) is a result of eliminating the power steering pump and has drastically changed the way we diagnose and repair steering systems. These systems first came about on production hybrid vehicles in the early 2001 Model Year Toyota Prius and have since made their way into many other production vehicles across all manufacturers. Although these systems have been around for more than 10 years, it is important that we know how the system works in order to fix them right the first time.
