Description
Technical field
The present invention relates to wheel steering system technical field, particularly relate to a kind of automobile electric power-assisted steering system
System.
Background technology
Electric boosting steering system (Electric Power Steering System, EPS) is a kind of straight
Connect the steering relying on motor to provide booster torquemoment.This system is different from traditional hydraulic power steering
System, it need not the mechanically and hydraulically control of complexity, but gathers the speed of automobile according to microprocessor
With the size and Orientation that the size of pilot control moment controls assist motor electric current, with realize to automobile
The purpose of steering wheel power-assisted.This method can be that arranging of steering characteristic provides sufficient degree of freedom, can essence
Power steering required for the different speeds that the most now people pre-set, different turning, can make driver
Obtain stronger road feel, lighter steering force, make vehicle have preferably and return stable stability, higher resisting
Interference and capability of fast response.Particularly it can solve the problem that pure hydraulic power steering is at galloping
Time steering wheel unstable problem, but also have efficient, energy-conservation, high-performance, low cost etc. are a series of has
Point.Therefore, electric boosting steering system replacement hydraulic power-assist steering system has become as Hyundai Motor development
Inexorable trend.
The effect of sensor is: moment of torsion that during detection Driver Steering Attention, steering wheel produces or corner big
Little and direction, and this information is converted to the signal of telecommunication is sent to electronic control unit (ECU), ECU is according to this
Individual signal produces corresponding power-assisted electric current together with signals such as speeds, drives motor to produce power-assisted, assists to drive
The person of sailing turns to.The research of state's outer sensor presents two development trends, and one is from providing single moment of torsion letter
Number to provide composite signal direction develop；Two is to develop to contactless direction from contact.Domestic for
EPS sensor has been also carried out certain research, but majority is also difficult to meet the requirement of auxiliary products.State at present
Interior for a EPS product, the sensor type that can select mainly has two kinds, a class Japan NSK
The torque sensor filled in prosperous river the Big Dipper EPS, two be BI company of the U.S. be that Delphi company is supporting
Moment of torsion, position compound sensor, some domestic manufacturer is at the base of foreign related sensor the most in recent years
On plinth, develop non-contact type inductance type torque sensor or Hall-type torque sensor, but do not have
Steering wheel angle sensor function.
The sensor that existing supporting EPS uses is the compound transducer of contact, the sensor of contact
The noise causing EPS is big；The sensor accuracy of existing structure is low, and the deviation of signal of collection is big, causes EPS
Low-response, the handling comfort of driver can be low；The sensor construction of existing structure is complicated, and volume is relatively
Greatly, the restriction ratio being subject to when the vehicle body layout of EPS is more；The sensor of existing structure based on contact,
In the use of EPS, producing spot corrosion abrasion, make reduce the service life of EPS assembly, follow-up maintenance is protected
Support difficulty.
