Description

The method and system of vehicle operating monitoring, parameter measurement, overload monitoring and supervision

Technical field

The present invention relates to technical field of vehicle, in particular, relate to the method and system of a kind of vehicle operating monitoring, parameter measurement, overload monitoring and supervision.

Background technology

The vehicle run on land is one of most important on our times, most basic transport facility; Because the life security of the safe in operation of vehicle and driver, occupant is closely related, improves the security monitoring performance of vehicle operating, be always the core emphasis of vehicle technology;

From textural division, vehicle has the generation power system of power, the machine driven system of transferring power usually; Power system has power supply device, power control unit, engine installation usually;

Divide from power system kind, vehicle has fuels and energy, electric driving force, hybrid power system etc.; Because fuel-powered vehicle easily causes serious environmental pollution, so for the research of electric driving force vehicle or motor vehicle driven by mixed power, there is even more important green, environment protection significance.

Existing electric driving force vehicle, comprises plug-in electric vehicle, fuel cell formula elec. vehicle etc.;

Existing motor vehicle driven by mixed power, then comprise two or more power system, as fuel powered systems and electric power system etc. simultaneously;

Existing elec. vehicle, has electric power system, machine driven system usually; Described electric power system generally includes supply unit, motor driver, motor; In the rotor of elec. vehicle, motor output shaft, drive wheel and the intermediate mechanical drive disk assembly between motor output shaft and drive wheel, any one or more parts also can be described as rotary work type power or the drive disk assembly of electric driving force vehicle; Power system, machine driven system also can be integrated by some wheel hub motor vehicle;

Because the rotary work type power of vehicle or drive disk assembly, unlike fixed working part or linear running type working part, various strain gauges can be installed easily and be convenient to detect each components interior stress state; As stress or torque sensor being installed on, fixed pedestal assembly is then not easy to detect the true stress situation of turning unit; As being installed on turning unit inside, then signal be not easy to transmission/or sensor electrical source supply device be not easy to arrange; So cause existing can be used for vehicle rotary work type power or the torque sensor of drive disk assembly with high costs; Low cost for the rotary work type power of vehicle or the operation conditions (especially early fault) of drive disk assembly is monitored, and is a professional difficult problem;

In order to solve the problem, prior art is divided into two large class solutions:

A, local device type monitoring scheme: existing tire pressure monitoring system can monitor tire pressure, to certain forewarning function of having blown out; But it only can monitor airtyred tire pressure, and usually can only could monitor when tire flat causes tire pressure or wheel speed marked change, respond partially slow; And the deformation (losing round) of tire, without monitoring capacity, is run without monitoring capacity for other rigid rotating parts (even to the wearing and tearing of air-inflation tyre self drive bearing); For adopting the vehicle (as high ferro, motor-car, ordinary train, electric locomotive, tracklaying vehicle) of rigidity drive wheel more without monitoring effect.

The maximum safe limit threshold values of B, universal vehicle operating parameters transfinites and compares type technical scheme:

In prior art, there is the technology of the join operation value of multiple acquisition vehicle mass; To carry out various variable speed control, braking and stability control, adaptive learning algorithms (ACC) system or certainly to move (LCX) system, ABS control etc.;

In prior art, more there is the technical scheme of multiple detection turning unit rotating speed, vehicular longitudinal velocity, longitudinal acceleration; Detected by sensor, analyzed by gps data, or carry out join operation etc. by other parameters, to realize the functions such as hypervelocity speed limit;

Because running conditions of vehicle has hundreds and thousands of kinds of possibilities, vehicle is in the switching of the states such as low speed/at a high speed, underloading/heavy duty, acceleration/deceleration, upward slope/descending at any time, so significantly changing also may appear in vehicle operating parameters (as longitudinal velocity, longitudinal acceleration, vehicle mass, vehicle drive force, torque, power, electric current etc.) in normal operational condition; So existing category-B technical scheme, all simply can only exceed maximum safe limit threshold values (as Maximum speed limit, peak acceleration limits value, maximum safety load amount, maximum power, maximum torque, maximum current etc.) in vehicle operating parameters and respond; Before vehicle operating parameters does not exceed default maximum safe limit threshold values, be not easy to realize the monitoring to vehicle operating safety case, be more not easy to realize highly sensitive early stage monitoring; Usually can only be passive, transmission main shaft fracture, the transmission gear explosion of delayed wait vehicle, be included in and blow out without during tire pressure monitoring system, just can warn after may causing the generation of the event of severe safety accident, deal with problems arising from an accident.

A kind of vehicle provided by the present invention is by the beneficial effect of method for supervising during engine installation controlling run and system:

By carrying out deep study and analysis to the transmission of power situation of vehicle: the operation essence of vehicle is exactly transformation of energy and power transmission process; Transmission of power situation of the present invention is also rotary work type power or drive disk assembly operation conditions; When vehicle is run by engine installation driving, first from power supply device (fuel supply device or supply unit), the energy is sent to engine installation (motor), energy conversion is power by engine installation, then transmits step by step through machine driven system, and then drives vehicle to move; The power supply device of vehicle and engine installation represent the supplier of power, and machine driven system represents the transmitter of power, and driven vehicle (together with the personnel loaded and article) represents the acceptor of power;

Comprise step in the steps A of method for supervising provided by the invention: obtain the measuring and calculating object of described vehicle with vehicle movement balance for principle calculates gained join operation value, described vehicle movement equilibrium principle essence is the combination of energy conservation principle and Newton's law and vehicle operating feature; In vehicle movement EQUILIBRIUM CALCULATION FOR PROCESS, vehicle driving source parameter represents the information provision of power (and energy), vehicle mass represents the most inherence of driving force receptor, and the system operational parameters of vehicle represents the motion result (as longitudinal velocity, longitudinal acceleration etc.) that the basic condition of transmission of power and vehicle produce under dynamic action;

If when there is inordinate wear or distortion/running resistance increase/efficiency step-down in the rotary work type power of vehicle or drive disk assembly in high-speed cruising: if monitored control system is using driving source parameter as measuring and calculating object, then when other relevant vehicle operating condition (as vehicle mass, road gradient, windage, longitudinal velocity, longitudinal acceleration etc.) are constant, more power must be expended and cause the deviate of the actual value of driving source parameter and vehicle movement EQUILIBRIUM CALCULATION FOR PROCESS gained join operation value to increase; If monitored control system is using longitudinal velocity in mechanical operating parameters as measuring and calculating object, power as vehicle output is also when the actual value of driving source parameter is constant and other relevant vehicle operating condition (as vehicle mass, road gradient, windage, longitudinal acceleration etc.) are constant, then the deviate of the actual value of the longitudinal velocity of vehicle and vehicle movement EQUILIBRIUM CALCULATION FOR PROCESS gained join operation value may be caused to increase; If using vehicle mass as measuring and calculating object and other relevant vehicle operating condition (as road gradient, windage, longitudinal acceleration etc.) constant time, then namely when also the actual value of driving source parameter increases power/or the actual value of longitudinal velocity of vehicle reduces time, then vehicle movement EQUILIBRIUM CALCULATION FOR PROCESS gained vehicle mass join operation value will be caused to change; So by by the measuring and calculating join operation value of object and reference value, (it sets according to actual value, and comprise transmission of power situation identification data) compare, just can judge that whether the transmission of power situation in described vehicle operating is abnormal, and start transmission of power exception handling in time;

Because reference value sets according to the actual value (and not according to maximum safe limit threshold values) calculating object, allow it much smaller than maximum safe limit threshold values; So when vehicle operating parameters does not exceed maximum safe limit threshold values, also be convenient to realize monitor and early warning the rotary work type power of vehicle or drive disk assembly operation conditions (also i.e. transmission of power situation), be convenient to avoid to occur more serious, uncertain safety misadventure (comprising off-axis, car crash etc.) as far as possible; As the cancer diagnosis of human medical, if just find late period usually to mean that life terminates, if life survive is meaned in early detection usually; So the technical program has important practical significance for the safe operation of vehicle.

4.1.3, road surface gradient theta: vehicle running surface or track and horizontal angle; When vehicle runs toward upward slope direction: 90 ° of > θ >0 °; Sin θ be on the occasion of, represent kinetic transformation become potential energy, than level run need consume more power;

When vehicle level run: θ=0, cos θ=1, sin θ=0;

When vehicle runs toward direction of fall: 360 ° of > θ >270 °; Sin θ is negative value, represents that potential energy becomes kinetic energy, less than level run consumed power, even may enter braking mode;

For the gradient θ of the track of electric power locomotive driving, also can represent with road surface gradient theta is equivalent;

θ value obtain manner 2: obtain concrete circuit, the θ value of track on particular location by GPS information or other pre-stored data storehouse, network system etc.; Especially for the rail cars such as high ferro, motor-car, because stock rail track is relatively fixing, can by preset location information and road surface gradient theta value (and/or together with bend coefficient δ and/or roll hinder coefficient f) corresponding data bank, when vehicle operating, table look-up according to location information and directly can read θ value (or together with δ and/or f); For automobile, if this path is the path of having passed by, having learnt, also this mode can be adopted;

4.1.4, the acquisition of windage fw, have following various ways:

Fw value obtain manner 1: the longitudinal velocity V first obtaining vehicle _xagain by calculating fw value; Calculating formula for reference is as follows: fw=(1/2) * C _d* (p0*A ₀* (V _x) ²); Wherein C _dfor the air resistance coefficient of vehicle, p0 is density of air, A ₀for the wind area of vehicle; C _d, p0, A ₀all belong to the intrinsic parameter of system, all obtain by reading system preset value; By measuring longitudinal velocity V _xand obtain windage fw, there is low, the easy advantage of cost; Survey precision is not high;

Fw value obtain manner 2: independently wind speed and direction testing tool is set on vehicle, when first measuring vehicle is run front windward speed V2 again by calculating fw value; Calculating formula for reference is as follows: fw=(1/2) * C _d* (p0*A ₀* (V2) ²); C _d, p0, A ₀all belong to the intrinsic parameter of system, all obtain by reading system preset value;

Because vehicle is in operation, if ambient wind velocity air-flow V0 direction is contrary with vehicle operating direction, actual V2 will be vehicular longitudinal velocity V _xwith V0 and, now vehicle operating windage fw increases; If ambient wind velocity air-flow V0 and vehicle operating direction are in the same way, actual V2 will be vehicular longitudinal velocity V _xwith the difference of V0, now vehicle operating windage fw reduces; So by obtaining front speed V2 and then acquisition windage fw value windward, adding cost but there is the high advantage of survey precision.

Fw value obtain manner 3: independently blast or windage sensor are set on vehicle, unit area blast or windage when direct measuring vehicle is run, and then go out windage fw value by Calculation of correlation factor;

Fw value obtain manner 4: the association table pre-setting a vehicular longitudinal velocity and windage fw value, when vehicle operating, is tabled look-up by the value of longitudinal velocity and draws corresponding windage fw value;

The windage fw when low cruise is less for vehicle, and when car speed is higher, windage is larger, so the measuring and calculating of windage fw has key role when monitor vehicle high-speed cruising.

4.1.5, bend coefficient δ: refer to turn round in the current operation of vehicle coefficient; When the vehicle is turning, the size of vehicle drive force will be affected; In general, camber is larger, and propulsive effort also increases;

The obtain manner 1 of bend coefficient δ: by running orbit or the acceleration pick-up of vehicle, measure and turn round angle [alpha] and then obtain δ value, calculating formula for reference is as follows: δ=K (α);

The obtain manner 2 of bend coefficient δ: by being arranged at the rotary angle transmitter of bearing circle, measure and turn round angle [alpha] and then obtain δ value, calculating formula for reference is as follows: δ=K (α);

The vehicle δ of different model may be different, the concrete numerical value of δ, the concrete functional relation of α angle and δ value, can be learnt by vehicle producer or professional testing agency or user turning test of in person driving; Easy in order to calculate, opposing straight or degree of turning round be less than the road surface of set angle (as 30 °), bend coefficient δ value can be set to 1 usually, or directly ignores δ, do not participate in computing;

Being described in detail as follows of the intrinsic parameter of system:

4.2.2, the efficiency factor Kea of electric power system, the efficiency factor Km of machine driven system:

4.2.2.1, the efficiency factor Kea of electric power system comprises and is not limited to following parameter:

The efficiency factor Ke of motor: the conversion efficiency of electric power to motor shaft output mechanical power referring to motor;

Motor driver is to the efficiency factor k21 (also can represent with k13) of motor: when referring to that motor operating condition is motoring condition, the horsepower input of this motor driver is to the conversion efficiency of the electric power of motor; Also the conversion efficiency of the horsepower output of power supply to the electric power of motor can be referred to;

Power supply is to the efficiency factor k31 of motor: when referring to that motor operating condition is motoring condition, the horsepower input of this power supply is to the conversion efficiency of the electric power of motor;

Motor braking power is to the efficiency factor k14 of power supply: from motor braking power to the efficiency factor feeding back to supply unit power when referring to motor braking state;

The efficiency factor Kem that Mechanical & Electrical Transmission is comprehensive, also can be described as Mechanical & Electrical Transmission combined efficiency Kem; Kem comprises the efficiency factor Ke of motor, contains the efficiency factor Km of machine driven system; Kem=Ke*Km.

4.2.2.3, associated efficiency coefficient k 31, k21, k14, Ke, Km, Kfa value is substantially constant in certain speed, load zones;

The change of k31, k21, k14 value means the inner rectifier bridge of power supply or motor driver, IGBT may exist short circuit or the abnormal condition such as open circuit, parameter variation; The change of Ke value means that motor internal rotating field parameter variation or motor short circuit in winding or open circuit etc. may cause the variation of serious consequence;

The Current Voltage rotational speed and torque of vehicle can become, but basic k31, k21, k14, Ke value can not become; So above-mentioned k31, k21, k14, Ke value is not only as the efficiency factor of electric power system, also can be used as the important evidence of the safety case of electric power system;

The change of the efficiency factor Km value of machine driven system may represent comprising in the machine driven system of power plant output shaft, drive wheel and the intermediate transmission parts between power plant output shaft and drive wheel of vehicle, occurs that severe wear or distortion or gear embrittlement etc. may cause the variation of serious consequence;

4.2.3 resistance coefficient f, is rolled: the scroll wheel and the road surface coefficient of rolling resistance that refer to vehicle;

4.2.3.1, the vehicle that travels on average highway, can use inflatable rubber tire, it rolls resistance coefficient f, primarily of air pressure p1, the wear condition kt of tire, the flat condition kr decision on road surface of tire, with mathematical functional expression, its value can be described: f (k0, p1, kt, kr); K0 is coefficient of correction, and p1 is tire pressure, and kt is wear on tyres state, and kr is condition of road surface.F a reference value under standard Attrition situation kt and standard pressure p1 and standard road conditions kr, can be set by vehicle manufacturers or professional testing agency.The f a reference value of vehicle, speed, load, even the gradient significantly changes time may occur to change by a small margin, by interval at different speed, load, road gradient, different coefficient of correction k0 can be set, revise the change of f benchmark.

Evenness of road surface situation kr changes, or the change of wear condition kt value, all can cause the change of f value; But kt change is individual process slowly can not cause the sudden change of f value; The change of evenness of road surface situation kr and cause the change of f, can pass through driver, the visual simple identification of passenger and resolution.

So when ignoring the change of kt, kr value, f value will determine primarily of tire pressure p1; Under equal road conditions, under equal load carrying ability, when tire pressure p1 is not enough, squeegee action larger (losing circularity larger), then f value is understood larger, and vehicle operating resistance can larger (more easily generate heat during high-speed cruising and blow out); Its principle is: circular object rolls easily, and then not easily, it is more difficult that polygon rhombogen, square, triangular form object roll ellipse;

F parameter is directly monitored as measuring and calculating object, or comprise f parameter in the join operation value calculating of other measuring and calculating objects and carry out indirect control and supervision, deformations of tyre (mistake circularity) can be monitored in vehicle operating, whether wear on tyres situation kt is abnormal, thus the risk of blowing out that can give warning in advance.In the vehicle high-speed operating period, if blow out suddenly accident, Leakage Gas causes deformations of tyre (mistake circularity) to increase rapidly, tire pressure p1 reduces rapidly, the join operation value calculating object can be caused to occur significantly to suddenly change, so utilize technical method provided by the invention, valuable early warning signal can be sent fast in the moment of blowing out.

From the principle Analysis of inflatable tire, the pressure that the deadweight due to vehicle produces, gas significantly reveal before internal pressure change be also slowly, wheel speed change be also slowly; As long as but tire leaks gas by a small margin, the weight because of vehicle causes deformations of tyre (losing circle) at once to produce; So abnormal by the monitoring deformation of the drive wheel (cause) running resistance change monitoring transmission of power, compared to relying on air pressure or relying on the prior art of wheel speed monitoring tire pressure, likely faster, effective.

4.2.3.2 the rail electric locomotive (as high ferro, motor-car, ordinary train, subway, tracklaying vehicle), travelled on trapped orbit, usual use rigidity scroll wheel, it rolls resistance coefficient f, primarily of scroll wheel self-deformation or and track between friction coefficient and wear condition determine; Rigidity scroll wheel cannot adopt the tire pressure monitoring technology of inflatable tire completely, usually can only carry out supersonic sounding that is artificial, sampling observation formula after a stop of the vehicle; So more need technical scheme provided by the present invention.

Judging that whether the transmission of power situation of described vehicle is abnormal according to the join operation value of described acquisition and the reference value of described measuring and calculating object, is one of core procedure of the present invention program; Transmission of power situation of the present invention is also rotary work type power or drive disk assembly operation conditions; Transmission of power situation extremely can be abnormal referred to as transmission of power;

Transmission of power of the present invention is abnormal to comprise in following 1A1,1A2,1A3 any one or multiple situation:

The difference of join operation initial value and described actual value described in 1A1. exceeds the first tolerance band (being also transmission of power situation identification difference);

Join operation initial value described in 1A2. exceeds the second tolerance band (being also transmission of power situation discre value);

As a rule, the setting principle of transmission of power situation identification data judged as transmission of power situation, set-up mode are identical; Second tolerance band (being also transmission of power situation discre value) sets according to the actual value of measuring and calculating object, be exactly try one's best close to this actual value to improve the sensitivity of monitoring, but the difference of certain quantity must be kept to reduce the false triggering rate monitored with this actual value; The difference of certain quantity described is the first tolerance band (being also transmission of power situation identification difference);

Second tolerance band (being also transmission of power situation discre value) can calculate according to described actual value and described first tolerance band (being also transmission of power situation identification difference) and obtain thus, first tolerance band (being also transmission of power situation identification difference) can obtain according to the second tolerance band (being also transmission of power situation discre value) and calculated with actual values in other words, and join operation difference carries out mathematic interpolation according to join operation initial value and described actual value; Three kinds of situations in abnormal 1A1,1A2, the 1A3 comprised of transmission of power, from practical solutions and effect, 1A1 is equal to 1A2 and is equal to 1A3, and just parameters input value is different, and describing mode is different;

Core concept of the present invention is exactly the reference value comprising transmission of power situation identification data that the join operation value of a certain measuring and calculating object sets with the actual value according to this measuring and calculating object compared in real time, process judged result in real time; Change a kind of implementation: the reference value 2 (also can be described as the second reference value) comprising transmission of power situation identification data according to the setting of join operation value, this reference value 2 (being also the second reference value) being compared in real time with the actual value (comprising measured value) of measuring and calculating object, process judged result in real time again, is also feasible; It is different that these two kinds of modes are only external expressive form, and in fact technical scheme, effect are equal to;

Wherein, described transmission of power situation identification difference (being also the first tolerance band) comprises any one or more data in transmission of power situation identification upper limit difference, transmission of power situation identification lower limit difference; Described transmission of power situation discre value (being also the second tolerance band) comprises any one or more data in transmission of power situation identification higher limit, transmission of power situation identification lower limit; Of the present invention exceed to comprise be greater than certain higher limit, be less than any one or the multiple situation such as certain lower limit;

Easy in order to describe, transmission of power situation identification upper limit difference also can be described as the first permissible upper value herein, transmission of power situation identification lower limit difference also can be described as the first permissible lower limit value, transmission of power situation identification higher limit also can be described as the second permissible upper value, and transmission of power situation identification lower limit also can be described as the second permissible lower limit value;

Herein, transmission of power situation identification difference (being also the first tolerance band) is generally certain numerical value positive and negative (as+10 and-10 etc.); Easy in order to what describe, when not distinguishing transmission of power situation identification difference positive and negative in while statement, can " transmission of power situation identification difference " representative " absolute value of transmission of power situation identification difference " be used;

Herein, two values that transmission of power situation discre value (being also the second tolerance band) is divided into transmission of power situation identification higher limit (being also the second permissible upper value) usually, transmission of power situation identification lower limit (being also the second permissible lower limit value) varies in size; Easy in order to what describe, when not distinguishing two values varied in size in while statement, " transmission of power situation discre value " representative " transmission of power situation identification higher limit (being also the second permissible upper value) " can be used;

Described 1A1 situation, specifically can to comprise in following 1A11,1A12 any one or two kinds of situations;

The difference of join operation initial value and actual value described in 1A11. is greater than transmission of power situation identification upper limit difference (being also the first permissible upper value);

The difference of join operation initial value and actual value described in 1A12. is less than transmission of power situation identification lower limit difference (being also the first permissible lower limit value);

Described 1A2 situation, specifically can to comprise in following 1A21,1A22 any one or two kinds of situations;

Join operation initial value described in 1A21. is greater than transmission of power situation identification higher limit (being also the second permissible upper value);

Join operation difference described in 1A32. is less than transmission of power situation identification lower limit difference (being also the first permissible lower limit value);

As a rule, allow the maximum safe limit threshold values of transmission of power situation discre value lower than measuring and calculating object of measuring and calculating object completely, also namely allow the second tolerance band of measuring and calculating object completely within the scope of the maximum safe limit threshold values of measuring and calculating object; Can break through existing known technology is not easy to carry out security monitoring limitation when vehicle operating parameters does not exceed maximum safe limit threshold values, details are shown in following example 1, example 2:

Example 1: as taken vehicular longitudinal velocity as measuring and calculating object, suppose that its (upper limit) maximum safe limit threshold values is 200KM/H, when supposing that vehicle runs with longitudinal velocity 60KM/H, then actual value is set to 60KM/H usually, then transmission of power situation identification difference can be set between 10-20KM/H usually, then transmission of power situation identification higher limit (being also the second permissible upper value) can be set between 70-80KM/H usually, then transmission of power situation identification lower limit (being also the second permissible lower limit value) can be set between 40-50KM/H usually; As long as then the join operation value of longitudinal direction of car running velocity is greater than transmission of power situation identification higher limit (being also the second permissible upper value) or is less than transmission of power situation identification lower limit (being also the second permissible lower limit value), described transmission of power situation judged result for abnormal, thus will can realize monitoring and protection; And now calculate object and exceed far away maximum safe limit threshold values (200KM/H);

Example 2: as with vehicle mass carried for measuring and calculating object, suppose that the maximum safe limit threshold values of its upper limit is limit for tonnage 7 people/560KG, when supposing that vehicle actual load 4 people/320KG runs, then actual value is set to 320KG usually, then transmission of power situation identification difference (being also the first tolerance band) can be set between 80-160KG usually, then transmission of power situation identification higher limit (being also the second permissible upper value) can be set to 480KG usually, then transmission of power situation identification lower limit (being also the second permissible lower limit value) can be set to 160KG usually; As long as then the join operation value of vehicle mass carried is greater than transmission of power situation identification higher limit (being also the second permissible upper value) or is less than transmission of power situation identification lower limit (being also the second permissible lower limit value), described transmission of power situation judged result for abnormal, thus will can realize monitoring and protection; And namely the transmission of power situation identification higher limit (also the second permissible upper value) now calculating object is far below maximum safe limit threshold values (560KG), the transmission of power situation identification lower limit of measuring and calculating object (also i.e. the second permissible lower limit value) is far above the minimum value (0KG) of threshold values under maximum safe limit;

Above-mentioned example 1, example 2 is apparent shows; The better setting value of reference value is:

As a rule, transmission of power situation identification upper limit difference (being also the first permissible upper value) is less than maximum safe limit threshold values maxim with actual value with value, and also namely transmission of power situation identification upper limit difference (being also the first permissible upper value) is less than the difference of maximum safe limit threshold values maxim and actual value;

Preferably, the absolute value of transmission of power situation identification upper limit difference is the smaller the better; Can improve the sensitivity of monitoring, but this absolute value can not be too small with the false triggering rate reducing monitoring;

As a rule, transmission of power situation identification lower limit difference (being also the first permissible lower limit value) is greater than maximum safe limit threshold values minimum value with actual value with value, and also namely transmission of power situation identification lower limit difference (being also the first permissible lower limit value) is greater than the difference of maximum safe limit threshold values minimum value and actual value;

Preferably, the absolute value of transmission of power situation identification lower limit difference is the smaller the better; Can improve the sensitivity of monitoring, but this absolute value can not be too small with the false triggering rate reducing monitoring;

As a rule, transmission of power situation identification higher limit (being also the second permissible upper value) is greater than actual value;

Preferably, transmission of power situation identification higher limit (being also the second permissible upper value) is less than maximum safe limit threshold values maxim;

As a rule, transmission of power situation identification lower limit (being also the second permissible lower limit value) is less than actual value;

Preferably, transmission of power situation identification lower limit (being also the second permissible lower limit value) is greater than maximum safe limit threshold values minimum value;

Further, transmission of power situation identification higher limit (being also the second permissible upper value) and/or transmission of power situation identification lower limit (being also the second permissible lower limit value) are more close to actual value, the sensitivity of monitoring can be improved, but the difference of certain quantity must be kept to reduce the false triggering rate monitored with this actual value;

In existing known solution, only maxim (560KG) or be less than minimum value (0) in maximum safe limit threshold values and just may respond in join operation value is higher than maximum safe limit threshold values; As long as vehicle mass is among maximum safe limit threshold values (maxim, minimum value), (even if the periproct compartment that in automobile 4 people, 3 people fall car or high ferro comes off) all can make the normal false judgment of safety case;

This programme step B is also one of important step of transmission of power abnormal monitoring scheme of the present invention; Transmission of power in vehicle operating is abnormal likely causes severe safety accident, needs to respond process in time;

B1 scheme: as described in judged result to comprise be then start the transmission of power exception handling of setting;

Steps A 3: after reference value sets, carries out in following 4 transmission of power situation Rule of judgment any one or more: Rule of judgment 1:((m1-m1_org) >m1_def1); Rule of judgment 2:((m1-m1_org) < (-m1_def2)); Rule of judgment 3:(m1>m1_ref1); Rule of judgment 4:(m1<m1_ref2);

Step B:

When reference value does not set or when vehicle is in astable driving condition (when Te is less than pre-set threshold value 1 (as rated value 5%)), directly perform step C; Can using engine installation braking mode, critical switch area all as astable driving condition in the present embodiment;

When reference value has set and engine installation operating condition is not in astable driving condition, perform following B1, B2, B3, B4 step side by side, then performed step C;

B1. if arbitrary judged result in 4 transmission of power situation Rule of judgment in steps A is yes, then transmission of power exception handling (as audio alert, light warning, startup transmission of power failure monitoring mechanism etc.) is started;

B2. to export in described judged result to network system, car in man-machine interface;

The alternate embodiment 1 of embodiment 41: in steps A, the setting of reference value is also feasible by external system; Only need read the outside reference value set in this step, then join operation value and reference value directly be judged;

The alternate embodiment 2 of embodiment 41: when the computation process of the join operation value of vehicle mass in steps A is not inner at this monitored control system, directly can read the result of the join operation initial value m1 that external device (ED) (as vehicle central controller etc.) inputs with alternative steps A1;

The alternate embodiment 3 of embodiment 41: when the computation process of the join operation value of vehicle mass in steps A is not inner at this monitored control system, directly can read the result of the join operation difference m1_def0 that external device (ED) (as vehicle central controller etc.) inputs with alternative steps A1, m1_def0=(m1-m1_org); Need not actual value m1_org be set in steps A 2, only need set transmission of power situation identification upper limit difference m1_def1, transmission of power situation identification lower limit difference m1_def2; In steps A 3, available m1_def0 directly substitutes the transmission of power situation that the value of (m1-m1_org) carries out Rule of judgment 1 or Rule of judgment 2 and judges;

The alternate embodiment 4 of embodiment 41: in steps A 3 when results any one or more in 4 transmission of power situation Rule of judgment is for being, obtain the running environment information with vehicle in same default time range during the value of join operation initial value m2, when judging that vehicle operating environment is normal according to the running environment information obtained, then generate transmission of power Reflector actv. information, trigger transmission of power failure handling mechanisms and carry out associated monitoring protection; When judging vehicle operating environmental abnormality, then still only trigger transmission of power exception handling;

The alternate embodiment 5 of embodiment 41: transmit situation identification upper limit difference m1_def1 and transmission of power situation identification lower limit difference m1_def2 according to fuzzy algorithm (when running as automatically selected the last time reference value) preset power in steps A 2.

The alternate embodiment 6 of embodiment 41: the electric driving force parameter related operation that in formula 41-2, expression formula (Ke*Km1*Te*im1) is front end, this expression formula also can substitute with (Km3_1*Tr3_1*im3_1), Tr3_1 is driving torque in the electric driving force parameter of rear end (available torque sensor collection signal), im3_1 is the transmitting ratio of the rear end of electric power system, and Km3_1 is the efficiency factor of the rear end of electric power system;

In method for supervising provided by the present invention, preferred version is the value of all parameters is Real-time Obtaining, and steps A, B are real-time execution, and performs with the circulation of the time cycle of setting, and this repetition period set is as more short better, the shorter sensitivity that more can improve monitoring and ageing.

Embodiment 1 to embodiment 33 and formula 13.1 to 13.6 herein, emphasis is for providing the embodiment calculating the join operation value of measuring and calculating object with vehicle movement balance for principle under numerous conditions; Embodiment 34 to 41 herein, emphasis is for providing the set-up mode of multiple reference value and judging the embodiment of transmission of power situation;

The present invention allows any one vehicle operating parameters as measuring and calculating object, arbitrary computing formula in REFERENCE TO RELATED file is allowed to be out of shape the account form as the join operation value of new measuring and calculating object, allow the acquisition join operation value of the join operation value of any one acquisition measuring and calculating object in REFERENCE TO RELATED file, the set-up mode of any one reference value in REFERENCE TO RELATED file is allowed to obtain reference value, any one transmission of power situation judgment mode in REFERENCE TO RELATED file is allowed to judge, any one subsequent treatment mode in REFERENCE TO RELATED file is allowed to process, new method for supervising can be built arbitrarily.

Such as can by longitudinal velocity V _xas measuring and calculating object, computing formula (m2=((Ke*Km) * (P2o/V in reference example 12 _x) – fw)/(g*f*cos θ+g*sin θ+a)), and then distortion, set up new account form: V _x=(Ke*Km) * P2o/ (m2* (g*f*cos θ+g*sin θ+a)+fw), and then other partial contents in REFERENCE TO RELATED file, using the measured value of longitudinal velocity as actual value and set reference value further, and then carry out the judgement of transmission of power situation, and then carry out the judgement post-processing of step B;

Such as can using the electromagnetic torque of the motor of vehicle as measuring and calculating object, computing formula (Te_cal=(m2* (g*f*cos θ+g*sin θ+a)+fw)/((Ke*Km) * im/R)) in reference example 28, the join operation value of reference example 41 or its alternative embodiment or its extension embodiment acquisition measuring and calculating object; And then its elsewhere content in reference example 40 or present specification, according to the measured value Te of electromagnetic torque as actual value and setting reference value, and then carry out the judgement of transmission of power situation, and then carry out the judgement post-processing of step B, as described in judged result comprise and be, start the transmission of power exception handling of setting and/or preserve judged result and/or export judged result;

The Selecting time of the value of parameter (as join operation value, reference value, calculating join operation are worth the value of required input parameter) and the explanation of acquisition time; Selecting time of the present invention, time when referring to that parameter generates, refers to the time calculated corresponding to the value of the required input parameter of this parameter; Because obtain and have various ways (reading, measurement etc.); As read in first 100 milliseconds of time1 time the parameter value that generates, then the acquisition time of this parameter is time1, but time of first 100 milliseconds when the Selecting time of this parameter is time1;

In the present invention, when described measuring and calculating object is arbitrary parameter in driving source parameter, mechanical operating parameters, mass change type article quality, more excellent scheme be all parameters (as join operation value, reference value, calculating join operation are worth the value of required input parameter) all in the time range preset value (as far as possible synchronous), calculate in real time, Real-time Obtaining (read or measure) join operation value and reference value, real-time judge, dispose judged result in real time, at this moment, the Selecting time of parameter can be equal to acquisition time;

When described measuring and calculating object is any one parameter in vehicle mass, the intrinsic parameter of system, the more excellent mode of Selecting time of join operation value (being worth the value of required parameter together with calculating join operation) be all in the time range preset value (as far as possible synchronous), calculate in real time, Real-time Obtaining (read or measure), carry out that transmission of power is abnormal judges/monitoring in real time; But the Selecting time of reference value (setting-up time) do not need with the Selecting time of join operation value at one time; The acquisition time (only needing to read) then carrying out the reference value before the abnormal judgement of transmission of power allows different from the Selecting time of reference value;

The mode 1 of the Selecting time of parameter value: value stricti jurise obtaining at one time multiple parameter, may be inconvenient to realize; In actual mechanical process, after having before the Selecting time of the value of each parameter group may have, only need the Selecting time of the value of each parameter to control at this moment in a default time range, this time range preset can according to the software processing speed of reality, Hardware Response Delay speed and determining; As desirable 100 milliseconds, or 10 milliseconds, or 1 millimeter, or 0.1 millisecond; This time range time of presetting is shorter, then calculate/monitor precision higher, but system cost also increases;

The mode 2 of the Selecting time of parameter value: if vehicle operating condition is substantially constant, the longitudinal velocity of such as vehicle travels at the uniform speed all maintaining 60KM within an hour, then get the currency of longitudinal velocity, and get the value of longitudinal velocity before 1 hour, effect is the same; So the time range preset of the Selecting time of each parameter value can adjust according to vehicle operating condition, also namely when vehicle operating condition is constant, the value of this parameter when condition of service is constant on any time point can be obtained.

The Selecting time of above-mentioned parameter value, the explanation of acquisition time are applicable to any embodiment of the present invention.

2. further, described method for supervising (#1) also to comprise in following 2A1,2A2,2A3,2A4 any one or plurality of step:

The implementation of the technical program: the object of this programme, is undertaken exporting and preserving by several data, exactly in order to automatic learning, generates the historic records value being convenient to transmission of power condition monitoring; Both directly (after also can adding the process such as deviate) can export and preserve each data; Historic records initial value is generated according to described join operation initial value, historic records actual value is generated according to described actual value, generate historic records difference according to join operation difference in described join operation value, generate historic records association factor value according to the value of described transmission of power situation association factor; Preferably scheme is, sets up the historical record data storehouse of comprehensive association according to the historic records association factor value of gained, historic records difference, historic records initial value, historic records actual value; Even the historic records value (this value can think relatively correct data) of a certain parameter can be drawn by table look-at according to the relevant parameter of this historical record data storehouse input when the judgement of follow-up transmission of power situation, transmission of power abnormal monitoring;

3. further, join operation value described in described method for supervising (#1) calculates and comprises the steps:

The implementation detail of this programme:

The join operation value of the described measuring and calculating object of described acquisition has various ways, a kind of is the join operation value reading the measuring and calculating object that other equipment exports, as the OBD system by vehicle, or motor driver reads the join operation value calculated, what only need this join operation value is for principle calculates gained with vehicle movement balance;

Also has a kind of mode, by with this monitored control system integrated design system, in monitored control system provided by the present invention, preset one vehicle movement balance computation rule (comprise Form Handle model, or formula of mathematical), obtain the value of the input parameter of described vehicle; Described input parameter is worth required parameter for calculating described join operation; Described join operation value is calculated according to the value of the input parameter of described acquisition; The Selecting time of the value of described input parameter is all in the time range preset;

As in previous embodiment 9, obtain the value of driving source parameter (electromagnetic torque Te), and obtain the value of vehicle mass (m2) and the value of system operational parameters (g, μ 1, θ, a, fw, im, R1) in the time range preset, then calculated the value of join operation value Kem_cal of the comprehensive efficiency factor of Mechanical & Electrical Transmission by the vehicle movement balance model that embodiment 9 provides;

As in previous embodiment 12, obtain the value of driving source parameter (motor exports electric power P2o), and obtain system operational parameters (Ke, Km, V in default time range _x, fw, g, f, θ, value a), then by vehicle movement balance model (m2=((Ke*Km) * (P2o/V that embodiment 12 provides _x) – fw)/(g*f*cos θ+g*sin θ+a)) calculate the value of m2;

4. further, in described method for supervising (#1) when described measuring and calculating object is arbitrary parameter in driving source parameter, mechanical operating parameters, mass change type article quality, described method for supervising comprises either a program in following 4A1,4A2:

The implementation detail of this 4A1 scheme: when measuring and calculating object is arbitrary parameter in driving source parameter, mechanical operating parameters, mass change type article quality, because the actual value in reference value or transmission of power situation discre value be possibility Rapid Variable Design all, so data in the measuring and calculating measured value of object, command value, measured projection value can be obtained, and according to the actual value in its setting reference value or transmission of power situation discre value; And need be limited in default time range with reference to the Selecting time of value and join operation value; This time range is the smaller the better; When the speed of a motor vehicle is standard value 120KM/H, per minute is 2KM, is per secondly about 33 meters, within 1 second, can differ 33 meters, 10 milliseconds of differences 0.33 meter; 1 millisecond differs 0.033 meter; The size of a Typical obstacles (as deceleration strip, stone) may at about 0.1 meter; The setting of this time range can adopt vehicle power to transmit the utmost dispatch of exception handling CPU as far as possible, can carry out 100,000 monocyclic ordering calculations in during 100M dominant frequency 1 millisecond;

The implementation detail of this 4A2 scheme:

Set described reference value according to historic records value and have two kinds of situations, one is according to historic records difference setting transmission of power situation identification difference; This is preferred version;

As for according to actual value in historic records initial value or historic records actual value setting reference value or/and transmission of power situation discre value time, must as far as possible ensure that vehicle operating condition is consistent; Such as when measuring and calculating object is driving source parameter, when the value of join operation value and the value of certain historic records value time vehicle operating condition close time (value of the transmission of power situation association factor of multiple core is close; As all close in vehicle mass value, road gradient, longitudinal velocity, the isoparametric value of longitudinal acceleration), then now the driving source parameter value of two different Selecting times may be also close; Concrete vehicle operating condition (threshold values as the weight of the number of the transmission of power situation association factor of core, each data, the diversity factor of each transmission of power situation association factor) is by user's sets itself, adjustment; Correlation parameter is more, weight setting is more reasonable, diversity factor threshold values is less, calculates/monitor precision higher;

5. further, in described method for supervising (#1) when described measuring and calculating object is arbitrary parameter in vehicle mass, the intrinsic parameter of system, described method for supervising to comprise in following 5A1,5A2,5A3,5A4,5A5 any one or kinds of schemes;

5A4. sets described reference value according to artificial setting value;

5A5. sets described reference value according to fuzzy algorithm.

The implementation detail of scheme 5A1: the setting principle of transmission of power situation discre value is under normal circumstances: be exactly as far as possible close to the actual value of measuring and calculating object to improve the sensitivity monitored, but suitable difference must be kept to reduce the false triggering rate monitored with actual value; As transmission of power situation identification higher limit being set to 1.2 ~ 1.5 times of actual value, or transmission of power situation identification lower limit is set to 0.7 ~ 0.9 times of actual value, or transmission of power situation identification upper limit difference is set to 0.1 ~ 0.3 times of actual value, or transmission of power situation identification lower limit difference is set to-0.3 ~ 0.1 times of actual value; But the accurate setting of this transmission of power situation identification data, as leaned on artificial try and cut method, or empirical method goes slowly to grope, and goes slowly to verify, transmission of power situation identification data Adjusting accuracy is low, efficiency is low; And the road conditions of different vehicle when running, carry condition, vehicle condition and change all the time, more increase the difficulty of the accurate setting of transmission of power situation identification data.

Setting described reference value (highest priority is transmission of power situation identification difference wherein or transmission of power situation discre value) according to the historic records value of described measuring and calculating object, is one of method for optimizing;

Before transmission of power situation judges, schemes generation historic records value in previously described 2A1,2A2,2A3,2A4 can be adopted; When described historic records value generates, described reference value (as to carry out in following 5B1,5B2,5B3,5B4 any one or plurality of step) can be set according to historic records value;

Historic records value described in 5B1. comprises historic records initial value and historic records actual value, and the difference according to described historic records initial value and described historic records actual value sets described transmission of power situation identification difference;

Described in 5B2., historic records value comprises historic records difference, sets described transmission of power situation identification difference according to described historic records difference;

5B3. described historic records value comprises historic records initial value, set described transmission of power situation discre value according to described historic records initial value;

In above-mentioned 5B1,5B2,5B3, common law is according to certain value 2 of certain value 1 setting; Certain can be worth 1 depending on feelings increase/or to reduce/or additional bias amount reset as certain value 2, can sweetly disposition;

The more excellent mode of reference value setting for: according to meet impose a condition time the join operation value that obtains set actual value in described reference value; According to the transmission of power situation identification difference in the historic records value setting reference value preset, both combine and can obtain desirable reference value, can improve the sensitivity of transmission of power abnormal monitoring to greatest extent, reduce the rate of false alarm of monitoring;

The implementation detail of scheme 5A2: when calculating the join operation value/of object or actual value may significantly change (especially the join operation value/of vehicle mass or actual value), or when the actual value of this measuring and calculating object is not easy to obtain, according to meet impose a condition time the join operation value that obtains to set described reference value be preferably mode; The visible previous embodiment 34,35 of specific embodiment etc.;

The implementation detail of scheme 5A3: by reference value described in systemic presupposition, comprises multiple predetermined manner: according to historic records value, fuzzy algorithm value, system default value preset reference value etc.; System default value is the simplest a kind of mode;

The implementation detail of scheme 5A4: set described reference value according to artificial setting value, comprises transmission of power situation identification data or together with actual value etc.;

The implementation detail of scheme 5A5: according to system default value setting reference value, lack alerting ability; Set described reference value according to artificial setting value, owe intelligence; Presetting described reference value through fuzzy algorithm is more excellent mode; Described fuzzy algorithm comprises following any one or multi-Fuzzy algorithmic rule: can according to the statistical analysis reference value that once access times are maximum in certain number of run; Or the reference value automatically selecting several recently to select number of times maximum in running; Or reference value when automatically selecting the last time to run; Or the different weighted index (as user preset most worthy, having the reference value of Protection significance most) arranging each reference value sets reference value; Or comprehensive number of times statistical analysis and weighted index and set reference value etc.;

6. further, also comprise the steps: the value of the transmission of power situation association factor obtaining described vehicle in described method for supervising (#1), adjust any one or more data in described reference value, described join operation value, described judged result according to the value of different transmission of power situation association factors.

The implementation detail of this programme:

During vehicle operating, the value of different transmission of power situation association factors, the change that the value generation amplitude of the vehicle operating parameters participating in vehicle movement EQUILIBRIUM CALCULATION FOR PROCESS is different may be caused, and then the join operation value calculating gained may be caused or/and reference value changes, and then the judged result of transmission of power exception may be caused to change; Set up the transmission of power situation association factor data bank with one or more transmission of power situation association factor, and how many parameters of this data bank can be set arbitrarily by user, cut randomly, be expanded arbitrarily by user;

Adjustment motivation of adjustment transmission of the present invention is abnormal judges data, comprises direct motivation of adjustment transmission and extremely judges data, as the judged result etc. of reference value, join operation value, transmission of power exception; Also comprise and judge data by the value Indirect method transmission of power of the vehicle operating parameters of adjustment participation vehicle movement EQUILIBRIUM CALCULATION FOR PROCESS is abnormal;

Such as different road gradients, different longitudinal velocitys, different vehicle conditions all may cause the resistance coefficient that rolls of vehicle to change, and then cause comprising roll the resistance vehicle movement EQUILIBRIUM CALCULATION FOR PROCESS gained join operation value of coefficient, reference value changes, and then causes the judged result of transmission of power exception to change; Such as, when car speed is higher, vehicle may be unstable, also may produce air lift force thus cause rolling resistance coefficient value (or vehicle mass bear gravity) change as aircraft principle vehicle; So can by setting up road gradient, longitudinal velocity, vehicle condition index and rolling the association table hindering coefficient (or gravity acceleration g value), participate in vehicle movement EQUILIBRIUM CALCULATION FOR PROCESS with the parameter value after adjustment, thus the transmission of indirect motivation of adjustment judges data extremely;

Such as, during the good index height of vehicle condition, or during the good index height of road conditions, or when carrying the good index height of condition, the absolute amplitude that can reduce transmission of power situation identification difference monitors sensitivity to improve; Otherwise when index as good in vehicle condition is low, or when the good index of road conditions is low, or when year good index of condition is low, the absolute amplitude of transmission of power situation identification difference can be increased to reduce rate of false alarm; Longitudinal acceleration as negative sense exceed certain threshold values (as vehicle be a significant slowdown time), the judged result of transmission of power exception directly can be set to not occur transmission of power abnormal;

7. further, also comprise following proposal in described method for supervising (#1): described join operation value carries out calculating gained respectively according to different engine installation operating conditions; Also namely first engine installation operating condition is obtained, by engine installation operating condition and described compute associations.

The implementation detail of this programme:

Vehicle is in acceleration or flat road surface or go up a slope in operation, is usually in engine installation driving condition; Vehicle, when slowing down or descending runs, is easy to enter engine installation braking mode; When driving source parameter can be easy measure positive-negative polarity time (as motor drive parameter or other measure the driving source parameter of gained by torque sensor) also allow to carry out calculating in engine installation braking mode join operation or the transmission of power abnormal monitoring of object;

As in embodiment 17 or shown in the alternate embodiment 9 of embodiment 41, first can use the engine installation operating condition of vehicle described in the supplying method identification of foregoing description institute, then carry out following calculating respectively; Also namely first engine installation operating condition is obtained, by engine installation operating condition and described compute associations:

When engine installation operating condition is engine installation driving condition, energy/power direction of transfer is generally and is delivered to car body from engine installation again through machine driven system, when calculating the join operation value of measuring and calculating object needs the value of driving source parameter to be multiplied by the efficiency factor being less than 1;

As in embodiment 17, when engine installation operating condition is engine installation braking mode, energy/power direction of transfer is generally and is delivered to engine installation from car body again through machine driven system, and the join operation value calculating measuring and calculating object needs the value of driving source parameter divided by the efficiency factor being less than 1;

The useful meaning of this programme: because vehicle is inevitable often enter deceleration or descending process, often enter engine installation braking mode; The research of existing known technology when carrying out the join operation calculating object for engine installation braking mode is also in blind area, existing known technology adopts same computing formula when driving and when braking, thus reduces the calculating/of join operation value and the accuracy of transmission of power abnormal monitoring of measuring and calculating object; This technical scheme provided by the present invention, obtain engine installation operating condition, by engine installation operating condition and described compute associations, relative to the calculating/of the join operation value that prior art significantly can calculate object and accuracy, the reduction rate of false alarm of transmission of power abnormal monitoring.

The implementation of this programme:

Mass change type article quality of the present invention mainly comprises fuel mass; Embodiment 1 provided by the invention is to embodiment 33, and all have ignored fuel mass, vehicular gross combined weight m2 adopts following computing formula: m2=m0+m1; Can apply well at plug-in pure electric vehicle and external power source formula elec. vehicle (as high ferro, motor-car, electric locomotive, tramway train);

In feulcell prototype elec. vehicle, when calculating measuring and calculating Object associates operation values as considered fuel mass, then will provide parameter measurement precision/transmission of power abnormal monitoring sensitivity further;

The acquisition methods of residual fuel quality mf0: scales remeasurement mf0 value; Or by level and capacity etc., first measure residual fuel volume, then go out mf0 value by Calculation of correlation factor;

The acquisition methods of consume fuel quality mf1: by flowmeter survey or read OBD data or read the fuel electric-control injection system data acquisition flow of consume fuel or volume, then the value of mf1 is gone out by Calculation of correlation factor;

The predication method of fuel mass: the value calculating mf1 or residual fuel quality mf0 with preceding method;

When measuring and calculating object is load quality m1, is first obtained the join operation value of vehicular gross combined weight m2 by vehicle movement EQUILIBRIUM CALCULATION FOR PROCESS, and then calculate m1 value (m1=m2-m0) by m2; Value as the value or acquisition (mf2-mf1) that obtain mf0 also passes through following formulae discovery m1 value; M1=m2-m0-mf0, or m1=m2-m0-(mf2-mf1), thus thus calculate gained m1 value more can improve transmission of power situation accuracy of judgement degree than not comprising fuel mass;

When measuring and calculating object is vehicular gross combined weight m2, obtained the join operation value of m2 by vehicle movement EQUILIBRIUM CALCULATION FOR PROCESS; Because fuel mass is in continuous consumption in vehicle operating, mf1 constantly increases/and mf0 constantly diminishes, and actual value m2_org is also constantly diminishing; As the value or acquisition (mf2-mf1) that obtain mf0 value and by following formulae discovery actual value m2_org:m2_org=m1+m0+mf0, or m2_org=m1+m0+mf2-mf1; Thus calculate gained actual value m2_org (this actual value is generally used for setting reference value) than not comprising fuel mass, more can improve the accuracy that transmission of power situation judges;

When calculate object be driving source parameter or system operational parameters (on-fuel quality) time, the value (being generally the actual value of vehicular gross combined weight m2) of required vehicle mass is worth by the join operation of vehicle movement EQUILIBRIUM CALCULATION FOR PROCESS measuring and calculating object, the value of the value or acquisition (mf2-mf1) that also can obtain mf0 adjusts (as: m2=m1+m0+mf0, or m2=m1+m0+mf2-mf1) in real time; Thus indirectly the join operation value accuracy in computation of object is calculated in adjustment, thus improve the abnormal accuracy judged of transmission of power;

When measuring and calculating object is residual fuel quality, is first obtained the join operation value of vehicular gross combined weight m2 by vehicle movement EQUILIBRIUM CALCULATION FOR PROCESS, and then obtain the join operation value mf0_cal:mf0_cal=m2-m0-m1 of residual fuel quality; Obtain (measuring gained by the LOAD CELLS of hydrogen fuel or level sensor) the measured value mf0 with the residual fuel quality in same time range during join operation value mf0_cal value, and using this measured value as with reference to the actual value in value, set transmission of power situation identification difference as mf0/5 simultaneously; Judge (| mf0_cal-mf0|> (mf0/5)) whether set up, if (| mf0_cal-mf0|> (mf0/5)), judge that transmission of power is abnormal;

When described mass change type article quality is except fuel mass, also comprise the quality of other article time, also can refer to said method calculate obtain;

The useful meaning of this programme: by obtaining, processing the mass change type article quality of described vehicle, can improve the design accuracy of parameter, improve sensitivity, the accuracy of monitoring in fuel quality fluctuations situation; Especially for fuel cell formula elec. vehicle, this technical scheme can follow the tracks of the change of fuel mass in fuel cell, significant.

9. further, the parameter participating in described calculating in described method for supervising (#1) comprises to roll in resistance coefficient, road gradient any one or two kinds of parameters.

The implementation of this programme: vehicle movement balance has multiple implementation:

Computing formula as embodiment 3: m1=(fq2-fq1)/(a2-a1)-m0; (formula A3-4-3)

Computing formula as embodiment 15: m2=((P2o_2/V _x2)-(P2o_1/V _x1))/(a2-a1)

Can be summarized by above-described embodiment 3 or embodiment 15: twice speed change difference formula vehicle movement EQUILIBRIUM CALCULATION FOR PROCESS formula: (m2=Δ F/ Δ a); Such computing formula, because taking twice speed change difference formula vehicle movement EQUILIBRIUM CALCULATION FOR PROCESS formula join operation vehicle mass value, eliminate in formula and roll resistance coefficient f, road surface gradient theta parameter, calculate simple, but must ensure that rolling in twice variable-speed operation hinders coefficient f, road surface gradient theta value calculates just accurately time equal, when θ or f in twice operation not etc. time, which result of calculation is forbidden; And such company also has a significant deficiency, must could run when running speed change twice, cannot run during Δ a=0.

And comprise in vehicle movement EQUILIBRIUM CALCULATION FOR PROCESS formula in embodiment 7,11,12 or embodiment 41 and roll resistance coefficient, road gradient, vehicle is at the uniform velocity with during speed change all can calculating, and result is relatively accurate, so there is higher accuracy, practicality relative to embodiment 3 or 15.

10. further, calculating object described in described method for supervising (#1) is any one parameter in vehicle mass, the intrinsic parameter of system, mass change type article quality.

The useful meaning of this programme:

Next is measuring and calculating object is mass change type article quality (fuel mass), because the change of fuel mass is relatively slow, effect is than good as measuring and calculating object using driving source parameter or mechanical operating parameters, but also need tracking measurement current actual value and set reference value at any time, there is the second inducement measured error; And join operation value and reference value all may be approached null value (during as low on fuel) and accurately cannot be calculated/monitor, there is error and the inefficacy of the 3rd inducement.

11. further, also comprise any one or more scheme in following 11A1,11A2,11A3 in described method for supervising (#1):

11A2. exports the numerical value of described vehicle mass;

11A3. preserves the numerical value of described vehicle mass.

The implementation of this programme:

If measuring and calculating object be driving source parameter or system operational parameters time, join operation value calculate needed for vehicle mass have multiple obtain manner, comprise artificial input, systemic presupposition etc.; But the value obtaining vehicle mass by vehicle movement EQUILIBRIUM CALCULATION FOR PROCESS is more preferably selected, because scheme can follow the significantly change of load quality automatically for this reason, improve transmission of power abnormal monitoring accuracy;

The implementation detail of the program illustrates:

Transmission of power is abnormal generally includes vehicle operating environmental abnormality, transmission of power fault (comprising monitored control system faults itself) etc.; Vehicle operating environmental abnormality comprises road conditions exception, carries condition exception, vehicle slip, inclination etc.; So the abnormal condition such as road conditions are abnormal, year condition can be got rid of by the running environment information obtaining described vehicle;

Typical case's road conditions are abnormal: the deceleration driven in flat road surface, the stone exceeding certain volume, fragment of brick, trees etc.; It is abnormal that typical case carries condition: the rolling of vehicle carrying individuals/article exception/beat;

Running environment information have multiple obtain manner: measure by relevant vibration sensor, acceleration pick-up the degree of jolting relative to road surface that vehicle is in operation, can identification road conditions abnormal condition initiatively; Measure by facilities such as optics, super sonic, infrared pickoff, radars and identify road conditions abnormal (accurately can identify height, the distance of foreign matter as Reverse Sensor); By the sliding humidity on rain propagated sensation sensor identification road surface; By the obliquity sensor of horizontally set or the inclination of acceleration pick-up identification vehicle; The skidding of vehicle by the rotary speed data of Vehicle Rotating Parts and the longitudinal velocity of actual measurement comparison and know; Also can by operating personal by visual, with sensation identify distinguish above-mentioned situation; The Selecting time of described join operation value and the Selecting time of described running environment information are all in the time range preset.

As measured external environmental information all normally there occurs transmission of power extremely, then directly can judge that vehicle is in transmission of power faulty condition; Transmission of power fault mainly comprises: the inordinate wear of vehicle revolving part, aging, explosion, and fracture, rotor seize, engine scuffing, drive wheel be locked, blow out; When the transmission of power failure monitoring mechanism of vehicle confirms transmission of power fault occurs, usually need at once to start the emergency treatment schemes such as deceleration, parking, fault warning;

External environmental information as measured has abnormal condition and to there occurs transmission of power abnormal, then can judge that the current transmission of power of vehicle may be cause because of external environment condition extremely; Vehicle can continue to send the abnormal information warning of transmission of power but not transmission of power failure message; Simultaneously vehicle can proceed monitoring and runs and judge whether transmission of power exception is eliminated with the elimination of running environment exception, if can not synchronously to eliminate or transmission of power aberrant continuation exceedes setting-up time, then still can judge transmission of power fault;

16. further, and transmission of power exception handling described in described method for supervising (#1) comprises startup transmission of power failure monitoring mechanism.

The implementation detail of the program illustrates: described transmission of power failure monitoring mechanism comprises according to running environment information identification transmission of power fault, according to any one or multiple processing mode in time filtering processing mode identification transmission of power fault; After seizure transmission of power is abnormal, restart transmission of power failure monitoring mechanism is also allow;

17. further, and calculating described in described method for supervising (#1) is that basis calculates with the model that vehicle movement balance is principle.

The implementation of this programme:

The join operation value of measuring and calculating object has multiple account form, and one is computation of table lookup; As the association table of the vehicle mass of first preset vehicle, driving source parameter, system operational parameters; When input wherein any two kinds of parameters time, computation of table lookup can go out the value of another parameter; Such as obtain the driving source parameter of vehicle, the value of system operational parameters; The join operation value of vehicle mass is gone out according to the value computation of table lookup of this driving source parameter, system operational parameters;

One calculates with model (also can be described as mathematical formulae); The aforesaid embodiment 1 ~ 33 of the present invention, embodiment 41 are and calculate join operation value by model;

18. further, and historic records value described in aforementioned 4A2 or 5A1 scheme is generated by any one or kinds of schemes in following 18A1,18A2;

18A1. is operationally generated by described vehicle;

18A2. when described historic records value comprises any one or several data in historic records initial value, historic records difference; In described historic records initial value, historic records difference, any one or several data are for principle calculates gained with vehicle movement balance;

The implementation of this programme: historic records value has multiple generating mode, can generate historic records value by manufacturer by unified for the vehicle of same model, even if but same model vehicle also will face parameter consistency problem, and especially longer problem is more serious the time of making the product; Historic records paper and reference value also can by computer or network system simulates/virtual reckonings of emulation vehicle operating, but virtual estimated value has departed from vehicle real working conditions, poor accuracy;

According to the description of the combined parameter of aforementioned driving source, electric power may be combined with out electrical energy; The present invention also allows to use the combined parameter of driving source of kind of energy (as the power consumption of section sometime or the summation of section acting sometime) as measuring and calculating object, to become energy transferring abnormal monitoring from transmission of power abnormal monitoring; Power and energy are easily obscured from physical conception, but for vehicle operating, both meanings are completely different; Power is energy time differential, has moment-fast speed concept, and energy is power in time accumulative, has the concept of time-lag-at a slow speed; Even if in seconds, using the energy of consumption per second as measuring and calculating object/directly monitored object, as previous analysis content, when vehicle runs with the speed per hour of 120KM may 1 second 33 meters, in the steep cliff that the distance of 33 meters is enough to cross highway barrier, be enough to crash into highway limit or rivers,lakes and seas, within 1 second, be enough to produce serious safety misadventure; From value, the design accuracy of vehicle operating parameters, 33 meters are also enough to cross peak, slope and become descending from upward slope, θ value is by just becoming negative, because the existence of typical calculation formula mesoslope resistance component (m2*g*sin θ) of vehicle movement equilibrium principle, during vehicle driving up and descending time driving source parameter generation is significantly changed, driving source parameter during upward slope is meaningless for transmission of power abnormal monitoring during descending, even draws judgement that is contrary, mistake; In like manner, because the existence of speed change component (m2*a), when the driving source parameter before the change of longitudinal acceleration a value is used for after the change of a value, transmission of power abnormal monitoring is meaningless; So carry out transmission of power abnormal monitoring by scheme provided by the invention, instant value driving source parameter (as instantaneous power, instantaneously torque, immediate current etc.) is preferably used to carry out real-time transmission of power abnormal monitoring; If use the combined parameter of driving source of kind of energy to carry out transmission of power abnormal monitoring effect, then need the time controling of energy accumulation to be obtained the smaller the better (as 100 millimeters, 10 milliseconds, 1 millisecond, 0.1 millimeter), if use the parameter such as the electric energy of 100KM, the average power of 100KM, vital transient dynamics is run for vehicle safety and transmits abnormal monitoring, early warning meaning will be had no, postmortem can only be played at most, deal with problems arising from an accident analyze function.

If carry out transmission of power extremely by the combined parameter of the driving source of kind of energy as measuring and calculating object, also need to possess step in core bracket (obtain join operation value and the reference value of measuring and calculating object, judge that whether transmission of power situation is abnormal, have clear and definite processing scheme to the judged result of transmission of power situation according to join operation value and reference value) and can refer to following embodiment 42:

Embodiment 42: this method for supervising comprises steps A, B, C;

Steps A: this step comprises steps A 1, steps A 2, steps A 3;

Steps A 1: first obtain each parameter (m1, m0, the mf0 in (read or measure) same time range, g, μ 1, θ, a, fw, V1, Km, Ke) value (if vehicle is plug-in pure electric vehicle, mf0 can be established zero or directly cancel this), and according to obtained each parameter value, calculate the join operation value Pm_cal of the electric power of motor, computing formula is as follows:

m2＝m1+m0+mf0，

Pm_cal＝(m2*g*μ1*cosθ+m2*g*sinθ+m2*a+fw)*V1/(Km*Ke)

And then join operation value Pm_cal (carrying out integral operation) is obtained the electrical energy value EM1_cal within 2 seconds, EM1_cal is indirect join operation value;

Steps A 2: above-mentioned acquisition Pm_cal and EM1_cal value while; Obtain (read power control unit measuring and calculating the data obtained or with power meter measures) electric power actual value Pm_r, and then obtain the measured value EM2 with the electrical energy in 2 seconds of the same period of EM1 by Pm_r integral operation, or directly measure with power electric meter and obtain EM2 value; EM2 is as actual value in reference value; Setting transmission of power situation identification difference EM_def3:EM_def3=EM2/10; Setting transmission of power situation identification higher limit EM_ref1:EM_ref1=EM2+EM_def3; Setting transmission of power situation identification lower limit EM_ref2:EM_ref2=EM2-EM_def3;

Steps A 3: carry out in following 4 transmission of power situation Rule of judgment any one or more: Rule of judgment 1:((EM1_cal-EM2) >EM_def3), Rule of judgment 2:((EM1_cal-EM2) < (-EM_def3)), Rule of judgment 3:(EM1_cal>EM_ref1), Rule of judgment 4:(EM1_cal<EM_ref2)

Step B: as in 4 transmission of power situation Rule of judgment in steps A 4, arbitrary judged result is yes, then start transmission of power exception handling (as audio alert etc.);

The replacement scheme 1 of embodiment 42: because carry out to driving source parameter the data that accumulated time or Integral Processing can obtain energy ezpenditure, the Selecting time of driving source parameter to be set within one day or with within an hour or 30 minutes or within 10 minutes or within one minute or within 30 seconds or within 20 seconds or within 10 seconds or within 5 seconds or within 2 seconds or within 1 second or within 0.1 second; Time is longer, and as more than 5 seconds 10 seconds etc., then the meaning of transmission of power abnormal monitoring is more weak; Time is shorter, and the response of transmission of power abnormal monitoring is faster, but (four inducements caused by) of join operation value, measured value, reference value measured error will be larger/effect is poorer/and cost also raises; As can be seen here, by driving source parameter or using the transmission of power abnormal monitoring effect of combined for driving source parameter (as energy) as measuring and calculating object, can not show a candle to vehicle mass or the intrinsic parameter of system as measuring and calculating object.

In above-mentioned transmission of power method for supervising and system, permission system switches measuring and calculating object as required, enables multiple measuring and calculating object even simultaneously, and multiple transmission of power situations of carrying out multiple difference measuring and calculating object judge; As both allowed to carry out the judgement of transmission of power situation and monitoring using vehicle mass as measuring and calculating object, also allow to roll resistance coefficient simultaneously and carry out the judgement of another transmission of power situation and monitoring as another measuring and calculating object, as long as it is abnormal that any one or more transmission of power situation judged result is transmission of power, then start transmission of power exception handling;

In monitor procedure, also allow systematic evaluation driving source parameter, as vehicle low-speed high-torque runs time, the parameter of torque type can be used as driving source parameter; As vehicle run with high speed low torque time, by the parameter of power type as driving source parameter, to improve the join operation value design accuracy of measuring and calculating object, the sensitivity of transmission of power abnormal monitoring can be improved;

Also allow with same measuring and calculating object, adopt multiple driving source parameter to carry out the measuring and calculating of multiple join operation values of same measuring and calculating object simultaneously, carry out multiple transmission of power situation and judge and monitoring; As in the high ferro of outside mains supply, take vehicle mass as measuring and calculating object, build a transmission of power situation using the electromagnetic torque Te of motor as driving source parameter and judge and monitoring #100 system, then this system can monitor motor and rear robot driving system; Simultaneously input electric power P3i using power supply judge as building another transmission of power situation for driving source parameter and monitor #101 system, then this system can monitor the supply unit of high ferro, motor driver, motor and rear robot driving system simultaneously; Motor and rear robot driving system is monitored iff enabling #100 system (not enabled #101 system), then can directly use the transmission of power situation of the supply unit of the electric power Pm of P3i and motor and efficiency factor k31 checking high ferro, motor driver whether normal, verification method is for judging whether the result of calculation of ((P3i*k31)-Pm) exceedes pre-set threshold value (as P3i/20), as exceeded then supply unit or motor driver operation exception;

By carrying out deep study and analysis to the transmission of power situation of vehicle: the operation essence of vehicle is exactly energy transferring and power transmission process; Transmission of power situation of the present invention is also rotary work type power or drive disk assembly operation conditions; When vehicle is run by engine installation driving, first from power supply device (fuel supply device or supply unit), the energy is sent to engine installation (motor), energy conversion is power by engine installation, then transmits step by step through machine driven system, and then drives vehicle to move; The power supply device of vehicle and engine installation represent the supplier of power, and machine driven system represents the transmitter of power, and driven vehicle (together with the personnel loaded and article) represents the acceptor of power;

Comprise step in the steps A of method for supervising provided by the invention: obtain the measuring and calculating object of described vehicle with vehicle movement balance for principle calculates gained join operation value, described vehicle movement equilibrium principle essence is the combination of energy conservation principle and Newton's law and vehicle operating feature; In vehicle movement EQUILIBRIUM CALCULATION FOR PROCESS, vehicle driving source parameter represents the information provision of power, vehicle mass represents the most inherence of driving force receptor, and the system operational parameters of vehicle represents the motion result (as longitudinal velocity, longitudinal acceleration etc.) that the basic condition of transmission of power and vehicle produce under dynamic action;

If when there is inordinate wear or distortion/running resistance increase/efficiency step-down in the rotary work type power of vehicle or drive disk assembly in high-speed cruising: if monitored control system is using driving source parameter as measuring and calculating object, then when other relevant vehicle operating condition (as vehicle mass, road gradient, windage, longitudinal velocity, longitudinal acceleration etc.) are constant, more power must be expended and cause the deviate of the actual value of driving source parameter and vehicle movement EQUILIBRIUM CALCULATION FOR PROCESS gained join operation value to increase; If monitored control system is using longitudinal velocity in mechanical operating parameters as measuring and calculating object, power as vehicle output is also when the actual value of driving source parameter is constant and other relevant vehicle operating condition (as vehicle mass, road gradient, windage, longitudinal acceleration etc.) are constant, then the deviate of the actual value of the longitudinal velocity of vehicle and vehicle movement EQUILIBRIUM CALCULATION FOR PROCESS gained join operation value may be caused to increase; If using vehicle mass as measuring and calculating object and other relevant vehicle operating condition (as road gradient, windage, longitudinal acceleration etc.) constant time, then namely when also the actual value of driving source parameter increases power/or the actual value of longitudinal velocity of vehicle reduces time, then vehicle movement EQUILIBRIUM CALCULATION FOR PROCESS gained vehicle mass join operation value will be caused to change; So by by the measuring and calculating join operation value of object and reference value, (it sets according to actual value, and comprise transmission of power situation identification data) compare, just can judge that whether the transmission of power situation in described vehicle operating is abnormal, and transmission of power abnormal monitoring and early warning can be realized in time by the treatment step after follow-up transmission of power situation judges;

Because include driving source parameter in the Output rusults of the join operation value of measuring and calculating object or input parameter, and reference value sets according to the actual value (and not according to maximum safe limit threshold values) calculating object, typically also namely allow the second tolerance band of measuring and calculating object completely within the scope of the maximum safe limit threshold values of measuring and calculating object, allow it much smaller than maximum safe limit threshold values; So when vehicle operating parameters does not exceed maximum safe limit threshold values, also be convenient to realize monitor and early warning the rotary work type power of vehicle or drive disk assembly operation conditions (also i.e. transmission of power situation), be convenient to avoid to occur more serious, uncertain safety misadventure (comprising off-axis, car crash etc.) as far as possible; As the cancer diagnosis of human medical, if just find late period usually to mean that life terminates, if life survive is meaned in early detection usually; So the technical program has important practical significance for the safe operation of vehicle.

Because electric driving force parameter, especially the utilization of motor driving parameter belongs to the technology that field of power electronics industry is known usually, is convenient to low cost, high-precision measurement, acquisition; Vehicle movement EQUILIBRIUM CALCULATION FOR PROCESS, belongs to car load vehicle operating control field industry technology; The invention drive parameter to combine with vehicle movement EQUILIBRIUM CALCULATION FOR PROCESS electric driving force parameter, especially motor, and then the creationary transmission of power abnormal monitoring field being applied to a brand-new vehicle, safe significant for vehicle operating.

The implementation of the technical program:

The technical program and aforesaid a kind of vehicle are by method for supervising during engine installation controlling run and system, there is the technical characteristic that part is identical, as the scheme of the join operation value of the measuring and calculating object of vehicle as described in acquisition in preceding solution, contain in the technical program the scheme of the join operation value of the vehicle mass obtaining described vehicle, both join operation values be all for principle calculates gained with vehicle movement balance; Of the present invention invalid, be included in that any position stops measuring and calculating, Stopping parameters obtains, stop to judge or make judged result invalid etc. any one or multiple processing mode.

But in follow-up step, the overload of the technical program judges, judge with the transmission of power situation of preceding solution, both have again essence, significant difference;

The object that overload judges is as follows: judge that whether the contained personnel/article of vehicle are overweight;

The technical scheme that overload judges: the set-up mode of benchmark: according to the legal load carrying ability of vehicle, also namely certain maximum safe limit threshold values arranges judgment standard; Concrete triggering mode: as long as namely vehicle mass starts warning more than 1.0 times of maximum legal load carrying abilities of vehicle;

The output action that overload judges: export overload signal, reminds driver and conductor to reduce carrying individuals/article quality.

The effect for transmission of power situation fault recognition that overload judges: typical situation as shown in background note of the present invention, when there is inordinate wear or distortion/running resistance increase/efficiency step-down in the rotary work type power of vehicle or drive disk assembly in high-speed cruising, transmit situation major failure/continuations and run as vehicle mass join operation value becomes 6 people/480KG/ vehicle power from 4 people and serious, uncertain safety misadventure (comprising off-axis, car crash etc.)/urgent needs may occur warn and process, the overload system of vehicle can be reported: situation normally/do not overload; When 3 people fall car/vehicle mass join operation value become 80KG time, the overload system of vehicle also can be reported: situation is normal/do not overload.So the overload system of routine is nearly unavailable to abnormal (the particularly transmission of power fault) monitoring and protection of vehicle power transmission.

Transmission of power situation of the present invention is abnormal to be judged;

Transmission of power situation judges object: identify the power of vehicle or the operation irregularity of driving system and even fault;

The set-up mode of the reference value that transmission of power situation judges: transmission of power situation discre value requires as far as possible near the actual value of vehicle mass, and this value can follow the drift of vehicle quality actual value flexibility; Transmission of power situation discre value both much smaller than the maximum legal load carrying ability of vehicle, also can be greater than the maximum legal load carrying ability of vehicle; If vehicle short-term is 1.5 times of rated load, nominal load work, then transmission of power situation identification range can be located between 1.4 to 1.6 times of load values; It is diverse for arranging benchmark with the maximum legal load carrying ability of the vehicle of fixed type, limiting equation.
