direction of play turning, parking, time and effort to turn around more easily.
1. Advantage electric power
* provided by the electric power assist unit, does not directly take up the engine power, but also eliminates the need for a pulley mounted on the engine and other components, the relative energy saving.
· Light compact mass, arrangement and facilitate assembly.
No other pump element, the latter does not need to replace the power oil, money and worry.
· manufacturers are increasingly popular, is the power steering system trends.
2. Principle of Electric Power Technology
The electric power steering system, i.e., EPS, is the abbreviation of ElectricPowerSteering. 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.
When the driver performs steering in the steering wheel, the steering wheel torque sensor detecting a steering torque and the magnitude of the voltage signal is conveyed to the electronic control unit, the electronic control unit detects the rotation torque sensor from the voltage signal, a rotational direction and a vehicle speed signal, etc., sent commands to the motor controller, the motor output corresponding to the magnitude and direction of steering torque, thereby generating auxiliary 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.
