Abstract

Electric Power Steering for automobiles is primarily an energy saving scheme. Steering is the term applied to the collection of components, linkages, etc. which will allow a vehicle like a car Electric power steering offers greater vehicle safety by adapting variable steering ratios to human needs, filtering drive train influences and even adjusting active steering torque in critical situations. This is the latest technology in steering system; this system is work without maintenance, and fast response comparatively mechanical steering system. This paper introduces the basic composition of the electric power steering system, and put forward the reasonable design solutions of the soft hardware and the correction methods of controller, given the main technology index of the controller. It then describes the mechanisms involved, and the nuts and bolts of the all electric power steering systems for automobiles. Actuators, sensors and controllers that make electric power steering a reality in modern automobiles are described subsequently. In addition, it can make cars even lighter and more fuel efficient when compared to those using hydraulic steering systems. The central electronic elements of today's power steering systems are modern 32-bit microcontrollers, ARM controllers (MCUs). Since power steering is a safety-critical function, it also requires new MCU elements that support the functional safety of the overall system.
