For solving this technical matters, the invention provides a kind of heavy motor vehicle retarder integrated control method, comprising following steps:
A), after car load retarder function is opened, first detect the slow switch of intelligence and whether activate, enter the slow function of intelligence if activated; If un-activation enters b;
B) detection judges whether retarder handle exists fault, and if there is no fault then enters handle controlling functions; If there is fault to enter d;
C) detect that retarder brake intelligence condition subsequent meets, enter d;
D) car load retarder function is closed.
Step a) described in the slow function of intelligence be a kind of control method based on brake pedal aperture Intelligent adjustment retarder B.P., its process does not need driver to regulate retarder handle.
Step b) described in handle controlling functions comprise conventional five grades of negative torque controlling functions and fixed speed control function, activate fixed speed control function when handle is positioned at 1 grade, activate conventional five grades of negative torque controlling functions when handle is positioned at 2 ~ 6 grades.
Step c) described in retarder brake intelligence condition subsequent comprise retarder handle and push 0 grade or pedal of stepping on the throttle.
Beneficial effect: the present invention from the management of car load dynamic assembly, the integrated angularly integrating control of brake system to be to expand the intellectuality, safety, convenience etc. of retarder function.Enforcement of the present invention, make heavy motor vehicle retarder can more effectively, more convenient, more intelligent, safer mode runs.
Accompanying drawing explanation
Fig. 1 is the diagram of circuit of control method of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is specifically described.
Fig. 1 is the diagram of circuit of control method of the present invention.
The present invention includes conventional five grades of negative torque controlling functions; Adjustable fixed speed control function; Intelligence retarder brake function; Retarder brake intelligence removing function; Retarder brake-applying handle self-diagnostic functions etc., specifically comprise following functions and step:
1. detect the slow switch of intelligence whether to activate: after car load retarder function is opened, first detect the slow switch of intelligence and whether activate.When after the slow switch activator of intelligence, system enters intelligent brake pattern.
Described intelligent brake pattern refers to by intelligent brake switch, realize Vehicular intelligent braking function, driver is not needed to regulate retarder handle gear in the process, the aperture Intelligent adjustment retarder B.P. of brake pedal is stepped on by means of only driver, assisting vehicle carries out brake snub, when driver's loosen the brake or the slow switch of intelligence are closed, intelligent brake pattern stops immediately.System software is by sending rotating speed/moment of torsion control command (TSC1 controls message) to retarder actr, control when brake pedal aperture realizes retarder 0% ~-100% moment of torsion in 0% ~ 25% scope, when brake pedal aperture is greater than 25%, now retarder performs maximum brake power i.e.-100% moment of torsion control, and the drag of vehicle routine starts to work simultaneously.Intelligent brake does not need driver to regulate retarder brake-applying handle just can realize retarder brake, reduces driver's labour intensity.
If the slow switch of intelligence is not activated, system can detect retarder missing handle state.
2. detect retarder missing handle state:, whether the voltage signal exported by monitoring retarder brake-applying handle is within the scope of the 0.80V ~ 3.80V of setting, detect and judge whether retarder handle exists fault, if there is no fault, then enter retarder handle controlling functions.
Described handle controlling functions comprises conventional five grades of negative torque controlling functions and fixed speed control function, fixed speed control function is activated when handle is positioned at 1 grade, activate conventional five grades of negative torque controlling functions when handle is positioned at 2 ~ 6 grades, exit handle controlling functions when handle is positioned at 0 grade.
Described conventional five grades of negative torque controlling functions are basic function of retarder, select to realize 0% to-100% moment of torsion controlling functions by the gear of 2 ~ 6 grades, retarder handle, system software, by sending rotating speed/moment of torsion control command (TSC1 controls message) to retarder actr, realizes 2 grades of correspondence-25% moments of torsion, 3 grades of correspondence-50% moments of torsion, 4 grades of correspondence-70% moments of torsion, 5 grades of correspondence-85% moments of torsion, 6 grades of correspondence-100% moments of torsion controls.
Under described fixed speed control function is applied to vehicle lower long slope operating mode, when retarder handle is positioned at 1 grade, constant speed descending function is realized by Vehicular multifunction handle plus/minus key assignments vehicle speed value, control program setting often clicks plus/minus key, the setting speed of a motor vehicle increases or reduces 1Km/h, and speed of a motor vehicle setting range is 20 ~ 80Km/h.The vehicle speed value that driver sets by system software sends to retarder actr by self-defining regulation speed message (CUS2), realizes descending fixed speed control.
If systems axiol-ogy retarder handle exists fault, then exit retarder handle controlling functions, but intelligent retarder brake function is unaffected.
If systems axiol-ogy retarder handle exists fault, and intelligent brake pattern is not also activated, then system can enter car load retarder function " shut " mode".
3. detect retarder brake intelligence condition subsequent: for avoiding safety misadventure, under any mode of operation of retarder, as long as systems axiol-ogy pushes 0 grade or pedal of stepping on the throttle to fast device handle, namely condition subsequent meets, then retarder brake intelligence removing function activates, control program exits retarder and controls, and guarantees security of system.
The present invention from the management of car load dynamic assembly, the integrated angularly integrating control of brake system to be to expand the intellectuality, safety, convenience etc. of retarder function.Enforcement of the present invention, make heavy motor vehicle retarder can more effectively, more convenient, more intelligent, safer mode runs.
The above-mentioned embodiment of the present invention, just casehistory, is not only, and the change within the scope of the present invention all or equivalent scope of the present invention is all surrounded by the present invention.
