Description
Affiliated technical field
The present invention relates to a kind of can be as required, the various faults of automobile artificially are set and remove the method and apparatus of set fault.Particularly can be implemented on each electronics assembly system experimental of real car or automobile, artificially control various faults and occur repeatedly or disappear, reaching can reusable education experiment purpose.
Background technology
Vehicle failure is meant automobile assembly or component assembly, has partially or even wholly lost the phenomenon of former design function.Vehicle failure is from being formed into development, be an extremely complicated process, particularly present employed automobile, great majority have all adopted electron controls technology, mechanical fault and electronic failure be weave in often, has more increased the difficulty of vehicle failure being carried out quantitative and qualitative analysis.Current, in Automobile Design manufacturing and automotive performance research field, most security performances of paying close attention to automobile that all concentrate on, as collision experiment etc., less Test to Failure relevant for automobile electronic system sensor, actuator and controller, after comprising that certain sensor or actuator break down, to the influence of whole automobile electronic system, even Effect on Performance research and experiment such as car load dynamic property, travelling, economy.
On the other hand, continuous increase along with automobile pollution, auto repair service industry has also obtained unprecedented development opportunity and development space, but the industry technology talent but lacks in a large number, and the sector just was defined as one of four talent in demand's industries by country before 3 years.In auto repair service industry, grasp is very rare at the advanced techniques talent of fault diagnosis, check and analysis and the maintaining of Auto Electronic Controlled System and sensor, actuator and ECU (automobile electronic controller) comprehensively, work is organized grade of skill evaluation and technical examination with traffic department, also is difficult to relate to this field.
The 3rd, at aspects such as automotive operation and service engineering vocational education, the trainings of industry professional technique, also lack a kind of can be on material object, make the recurrent device of fault of the various sensors of automobile electronic system, actuator and ECU, so that carry out the education activities of fault detect, fault diagnosis, fault eliminating repeatedly, by the mode of " recurrence of failure, process are recurred ", carry out the diagnostic method at vehicle failure, the exercise that repeats of overhauling flow process, maintenance process and working specification truly.We can not wait until that vehicle failure has really occurred, and organize and how remove to learn diagnostic analysis before everybody.
Summary of the invention
At the problems referred to above, the invention provides the method and apparatus of a kind of vehicle failure setting and fault clearance, it is to go up relay group of connection or light lotus root group (Fig. 1-5) at automobile or each assembly experiment table of automobile (Fig. 1-1), the circuit of automobile or each assembly of automobile (Fig. 1-4) is connected on this relay group or the light lotus root group (Fig. 1-5), it in fact also is a control module (Fig. 1-5), can be installed in automobile, different positions such as each assembly experiment table of automobile (Fig. 1-1) and switch board, use connector to be connected with automobile or each automobile assembly controller (Fig. 1-2) connector, also can directly be connected with the control wire harness (Fig. 1-3) of automobile or each assembly experiment table of automobile, very convenient quick.Connect finish after, failure button, telepilot (Fig. 1-7) or computing machine (Fig. 1-8) mouse that operational failure is provided with in the case (Fig. 1-6) are handled, and just can realize dissimilar faults such as the opening circuit of each assembly control circuit of automobile or automobile, short circuit, overlap joint.Another kind of mode is to revise the normal signal of automobile electric control system: one of its method is the sensor and actuator at linear resistor type, mode by the variable resistor (Fig. 2-4) of a band of series connection gauge outfit on circuit, revise the signal (Fig. 2-3) of feedback ECU, make ECU produce erroneous calculations, and then the action that makes a mistake of control actuator, it is not in place that actuator is moved.The third mode is to disturb the normal signal of automobile electric control system: one of its method is that vehicle-mounted CAN bus and multistation information transmission system are applied an interference source (Fig. 3-6), influence the data transmission quality (Fig. 3-4) of network system, also can disturb the pulse signal (Fig. 3-5) of speed probe, realize the actual generation of fault.The single number of defects can also be provided with combined failure more than 40, i.e. the out of order while of firing system, oil supply system also has fault, and the electronics gas handling system also has fault.The realization of above-mentioned all kinds fault all is real, can make the different failure code of ECU (Fig. 1-2) storage according to the difference of vehicle, and cause the change of dynamic dataflow parameter.Bad from seeing each assembly system works of automobile or automobile in appearance, as engine can't starting, starting difficulty, idling speed is higher or on the low side, to quicken sluggishness, idling tourist bus, exhaust emissions abominable etc.Use automobile fault diagnostic apparatus can read these fault datas and failure message.Scope letter lid all the sensors, actuator and ECU that fault occurs; The character that fault takes place comprises and opening circuit, short circuit, overlap joint, bonding, signal are too high, signal is crossed low etc.; Fault relates to type and mainly contains feedback signal fault, supply voltage fault, reference voltage fault, correction signal fault, control circuit fault and data transmission quality fault etc.Use automotive service equipements such as multimeter, automobile oscillograph, engine multi-tester, exhaust analyzer can collect relevant fault data and failure message.
By above-mentioned design, beneficial effect of the present invention is: the appearance of above-mentioned all kinds fault can take place at any time with removing, and all is controlled in the safe scope, can not cause any infringement to automobile or each assembly of automobile.The method and apparatus of fault setting and removing is applicable to various ways: both be applicable to automobile, also be applicable to each assembly experiment table of automobile; Both be applicable to each assembly experiment table of static automobile or automobile, also be applicable to dynamic traveling automobile.Its structure and with being connected as shown in drawings of automobile or each assembly experiment table of automobile:
