Advantages
· electric power provided by the engine power, the engine power is not directly occupy, also eliminates the pulley mounted on the engine and other components, the relative energy saving.
· Light compact mass, arrangement and facilitate assembly. No pumps and other components, the latter do not need to replace oil power, peace of mind save money.
· manufacturers are increasingly popular, is the power steering system trends.

Technology Principle
The electric power steering system, that EPS, Electric Power Steering is the English abbreviation. The system provided by the electric power steering unit directly, eliminating the need for hydraulic power steering systems necessary power steering pump, hoses, hydraulic fluid, and a belt pulley mounted on the engine. The steering wheel steering
When a driver steering the steering wheel, torque sensor detects rotation andThe size of the moment, the voltage signal is supplied to the electronic control unit, an electronic torque control voltage signal, a vehicle speed signal means and the rotational direction detected by the torque sensor, the motor controller issues a command to the motor output corresponding to the magnitude and direction steering torque to generate assisting power. When the vehicle is not turning, the electronic control unit does not issue an instruction to the motor controller, the motor does not operate.
The electric power steering system has three ways, namely a steering shaft assist type, gear assist type, rack-assist type.
