1, only when the steering motor to provide power, can significantly reduce fuel consumption

The traditional hydraulic power steering system is driven by the engine to the oil pump, whether or not to use the engine to consume some power. And the electric power steering system is only in the direction of the motor to provide power, do not turn when the energy consumption. Therefore, the electric power steering system can reduce the fuel consumption of the vehicle.

Compared with the hydraulic power steering system test shows that: in the non steering, electric power steering can reduce fuel consumption by 2.5%; in the steering, can be reduced by 5.5%.

2, the steering booster size can be adjusted by software, can take into account the low speed when the steering portability and high speed of the steering stability, back to the good performance.

The traditional hydraulic power steering system can not be changed with the increase of the speed. This makes vehicles while at low speed with good steering portability, but in high speed steering wheel too light, to generate a steering floating phenomenon, the driver is missing significant "road feel, reduced the speed driving stability of the vehicle and the driver's sense of security.

Electric power steering system to provide the power of the size can be easily adjusted by software. At low speed, the electric power steering system can provide larger power steering. Provide a vehicle steering portability; with the increase of speed, the electric power steering system provides power steering can be decreased, steering the driver needed to provide steering force will gradually increase, so the driver feel obvious "road feeling and enhance vehicle stability.

Electric power steering system can also be applied to certain additional back to positive torque or damping moment and the low speed steering disc can accurately back to the middle position, and can inhibit the high-speed back is in the process of turning disk oscillation and overshoot, taking into account the high vehicle, low speed back is to.

3, the structure is compact, the quality is light, the production line is good, easy to maintain.

Electric power steering system cancels the hydraulic steering oil pump, an oil cylinder, a hydraulic pipeline, oil tank, etc. component, and the motor and speed reducing mechanism and steering column, a steering gear into a whole, makes the steering system has the advantages of compact structure, light weight, in production line assembly and assembly time saving, easy maintenance.

4, through the program settings, electric power steering system is easy to match with different models, can shorten the cycle of production and development.

Because the electric power steering system has many advantages, it has been widely used in recent years.

The electric power steering system is based on the mechanical steering system, which is equipped with motor and speed reducer, torque angle sensor, speed sensor and ECU electric control unit.
