Power steering in the automotive industry has evolved in the last few years and differs between all manufacturers. The general concept remains the same, which is to make the operation of the vehicle as comfortable and safe as possible. In the early days, the power steering system on cars was simple and made up of a hydraulic power steering pump, which via hydraulic pressures applied to the steering box or steering rack, assisted the driver in his actions. In cars today, electronics have taken over some of the controls, or perhaps even replaced the hydraulic system completely.
