Description
Technical field
The invention belongs to power assembly technical field of measurement and test, more particularly to the power train in vehicle application assembly based on virtual car load are comprehensive
Close the structure and working principle of test system.
Background technology
As the whole world reduces discharging require increasingly strict to automobile energy-saving, the power assembly of vehicle also by traditional start motor-driven
Power assembly develops to the method for new pure electric power assembly, hybrid power assembly.The development of power assembly, is meeting energy-conservation
While reduction of discharging is required, also so that the structure of power assembly is increasingly complicated, power assembly test is thus brought, demarcated, mated work
What work was measured steeply rises.In traditional power assembly test system (as shown in Figure 1), only the base frame module 18 of bag and it is based on
The host computer collection of industrial computer 19, record, control software, the design of experiment flow rely primarily on the artificial of experimenter with control
Control, automaticity are low；The control of experimental stand is confined to the directly controlled quentity controlled variable such as assembly throttle, dynamometer machine loading；Power is total
The test that carries out part, assembly rank is merely able to into test, it is impossible to carry out the test under car load environment, cannot also consider people-car-
Coordination control and the test on road；Experimental record is limited only to the record of experimental data, to experiment flow no record, it is impossible to complete
Reproduce whole experiment process.In this case, traditional power assembly test bench automaticity is low, single function scarce
Point increasingly manifests, it is difficult to the test of competent complicated new type power assembly, demarcation, the requirement of coupling.
Power train in vehicle application assembly practitioner both domestic and external throws attention in the improvement of power assembly technology, and for
The research of power assembly test experimental bed is less, and existing research has carried out less changing on the basis of conventional measurement laboratory table
Dynamic, such as patent of invention CN201210162174.9, CN200610063746.2, CN200410012522.X is to stand itself
Less change is carried out, for traditional stand automaticity is low, single function shortcoming has no significant improvement.
Patent CN101916519A discloses a kind of driving simulation test method for power system of electric automobile field, should
Method is by the setting to target vehicle speed-time parameter, different vehicle technical parameter etc., by car load Cable Power Computation and coupling
The different commands such as rotating speed under different speeds are obtained, allows each part of electric powered motor test-bed to carry out corresponding actions, so as to
The drive simulation experiment under predetermined different road conditions, different vehicle model is completed, can be according to collection note after off-test
The related data that records is analyzed, and so as to obtain the correlated performance analysis report of dynamical system, completes electric powered motor system
Driver simulation experiment of the system on test-bed.In that patent, it is achieved that carry out the test of automobile dynamic system on stand
Function, but for how to realize Cable Power Computation machine coupling there is no detailed elaboration, not to consider driver driving behavior to car load
The impact that causes of test, to experimentation in data record, analysis journey only lack related elaboration and the analysis of experimental data
Can carry out offline, additionally, this experimental technique has also abandoned part that traditional experiment stand can carry out (such as electromotor, motor
Deng) test function, utilization rate of equipment and installations is not high enough.

Operation drive simulation unit, according to the traffic information stored in drive simulation unit, simulates the work of various operating mode lower transmission systems
Make situation, and by operator process of the test data Cun Chudao data memory module, in driver to various operating modes all moulds
After having intended, non-driver operator scheme is initially entered, by control system according to the data stored in data memory module to quilt
Survey drive system to be controlled, by, under non-driver operator scheme, simulating repeatedly various operating modes, completing correlation test.Should
Patent solves the intrinsic Operation mode cycle system of conventional truck Approach for Vehicle Transmission System Test Bench and is unable to accurate response automobile actual moving process
In dynamic property, the problem of the related performance indicators such as economy.The patent is carried out to power assembly by introducing true driver
Control, overcomes intrinsic state of cyclic operation to be unable to the shortcoming of vehicle actual operating mode, but how anti-this patent is to vehicle, traffic information
The driver that feeds is not illustrated；Reproduction to driving cycle, employs the method for directly recording its behavioral data, the method
Defect is that the behavioral data of record is suitable only for corresponding state of cyclic operation, and is not suitable for new operating mode, from another
Individual aspect says that the method cannot depart from the operation of true driver when in the face of new operating mode；Additionally, this laboratory table and patent
CN101916519A has equally abandoned part (the such as electromotor, motor etc.) test function that traditional experiment stand can be carried out, if
Standby utilization rate is not high enough.
