Abstract
The invention discloses a control method for auxiliary braking of a heavy truck. According to the control method, the auxiliary braking process is divided into five gears, namely, the B gear, the first gear, the second gear, the third gear and the fourth gear, the five gears are controlled through a handle, the gears provide different auxiliary braking forces according to different requirement levels, and therefore the braking requirements of different road conditions are met, wherein the B gear and the fourth gear judge whether engine braking needs to be started or not according to the retarder intervention proportion, and when the retarder intervention proportion reaches 100%, engine braking intervenes; the control method is in linkage with ABS control, when an ABS detects that a wheel is about to be locked, or a rear wheel slips too much, auxiliary braking is out of work; after locking is removed, auxiliary braking works continuously. According to the control method, a proper, safe, convenient, rapid and effective auxiliary braking method can be provided according to various actual running working conditions, the use frequency of main braking is effectively reduced, and the economical efficiency and safety of vehicle running are promoted.
Description
Technical field
The present invention relates to automobile brake technical field, especially relate to a kind of control method for heavy truck auxiliary braking.
Background technology
In recent years, along with the development of truck technology, safety, the convenience of use and comfortableness that vehicle is run by people required also more and more higher.Current domestic Ge great main engine plants are all in the exploitation carrying out the coupling auxiliary brake vehicles such as retarder, but due to the hysteresis quality of technology with arrange the limitation of coupling, major part producer auxiliary braking control method can not realize effective grading control；Or auxiliary braking can not link with engine braking, it is provided that additional braking force limited, it is impossible to meet the part limiting condition demand to additional braking force；Some even can not control linkage with ABS, causes the various unstable situation brought under Part load because of wheel lock up.One heavy truck being equipped with the auxiliary brakings such as retarder, if it can not be realized safely, conveniently, effectively be controlled, not only can cause the very big complaint of user, more likely bring bigger potential safety hazard.
Summary of the invention
The technical problem to be solved is to provide a kind of control method for heavy truck auxiliary braking for problems of the prior art, its objective is to make auxiliary braking all adequately and reasonably be applied under various operating modes, promote safety and the convenience of use simultaneously.
The technical scheme is that this kind control method for heavy truck auxiliary braking, auxiliary braking is divided into five shelves by described control method, i.e. B, 1,2,3,4 grade, five gears are controlled by a handle, each shelves provide different additional braking force according to different demand classification, meet the braking requirement of various different road conditions；Wherein, B shelves and 4 grades are got involved ratio according to retarder and are judged that engine braking is the need of opening, and when retarder intervention ratio reaches 100%, namely engine braking gets involved work；Described control method controls linkage with ABS, and when ABS detects certain wheel by locking, or when multiple slip occurred in certain trailing wheel, namely auxiliary braking deactivates, and after locking releases, auxiliary braking works on.
Described auxiliary braking and the mutual communication of ABS, the testing result according to ABS, auxiliary braking completes to deactivate or work on.
This kind can not only provide suitably according to the various operating modes of actual motion for the control method of heavy truck auxiliary braking, safely, conveniently, effective auxiliary braking method, effectively reduce the frequency of usage of main brake, promote economy and safety that vehicle runs.The present invention is simple to operate simultaneously, dependable performance, it is easy to realize and less costly.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is the present invention flow chart for the control method of auxiliary braking system.
Detailed description of the invention
Fig. 1 is the present invention flow chart for the control method of heavy truck auxiliary braking.Flow process is known as shown in Figure 1, auxiliary braking is divided into five shelves for heavy truck auxiliary braking, control method by this kind, i.e. B, 1,2,3,4 grade, five gears are controlled by a handle, each shelves provide different additional braking force according to different demand classification, meet the braking requirement of various different road conditions；User, according to different road conditions, different demands, is allocated to different gears, to provide different additional braking force.Wherein, B shelves and 4 grades are got involved ratio according to retarder and are judged that engine braking is the need of opening, and when retarder intervention ratio reaches 100%, namely engine braking gets involved work, to provide sufficiently large additional braking force；Described control method controls linkage with ABS, and when ABS detects certain wheel by locking, or when multiple slip occurred in certain trailing wheel, namely auxiliary braking deactivates, and after locking releases, auxiliary braking works on.
Auxiliary braking and the mutual communication of ABS, when ABS detects that certain wheel multiple slip occurred by locking or certain trailing wheel, namely auxiliary braking deactivates, and after locking releases, auxiliary braking works on.
This kind can not only provide suitably according to the various operating modes of actual motion for the control method of heavy truck auxiliary braking, safely, conveniently, effective auxiliary braking method, effectively reduce the frequency of usage of main brake, promote economy and safety that vehicle runs.The present invention is simple to operate simultaneously, dependable performance, it is easy to realize and less costly.
