Description
Technical field
The present invention relates to the automobile experiment teaching field, in particular to a kind of control device of teaching vehicle, use the teaching vehicle of this control device and the vehicle teaching system that constitutes by this control device and teaching vehicle.
Background technology
Along with the continuous development of auto industry and improving constantly of people's living standard, automobile has become the walking-replacing tool of popularizing day by day.Meanwhile, the portfolio of auto repair also constantly increases, and the working troop of auto repair also grows stronger day by day.Yet, on the one hand,, more and more higher to Automobile Service personnel's requirement along with the continual renovation and the development of automotive engineering; On the other hand, present Automobile Service personnel amount still can not satisfy the needs of growing auto industry.Therefore, how to cultivate a large amount of high-caliber auto repair personnel apace, become development auto industry inevitable problem.
In the motor vehicle repair process, detect and the diagnosis vehicle failure is a very critical step because diagnostic result accurately whether directly determining quality and the efficient that follow-up work (as fixing a breakdown) is finished.Therefore, raising Automobile Service personnel are very necessary to the ability of vehicle failure detection and diagnosis.
In the prior art, the existing various teaching equipments that are used to train Automobile Service personnel detection and tracing trouble.Particularly, mainly comprise two classes: a class is a teaching demonstration equipment, as disclosed automobile cruise electronic control system demonstrator among the Chinese utility model CN2824190 that announced on October 4th, 2006; Another kind of is to simulate the teaching test vehicle (true car) that fault is set.First kind teaching equipment is owing to breaking away from true car, and is directly perceived inadequately, vivid for the student, thereby often can not reach good teaching efficiency.By contrast, the second class teaching equipment is more directly perceived, helps the student to understand, but bulky usually, cost is higher.And second kind equipment of the prior art, it is very limited to simulate the fault that is provided with, and the teaching equipment (true car) of a cost costliness of this meaning can only be used for the less relatively content of professor, and " cost performance " is not high.For example, the teaching test vehicle of " smart car " has abroad appearred being called in last century end to the beginning of this century, this laboratory vehicle is actually from the input end of motor car engine computer input electricity bundle socket is pulled up, reconfiguration is to the box that is called " BOB " (actual is a switch control enclosure), again from " BOB " box bundle of outputs to automobile computer.Cut off a certain circuit that is input to automobile computer by switch control, make it to produce corresponding phenomenon of the failure " BOB " box.This teaching test vehicle only can be simulated and be produced some partial fault that motor car engine is subjected to computer control, and instructional function is very limited, and therefore cost is higher comparatively speaking; In addition, this teaching test vehicle does not provide the approach that its fault is detected and diagnoses yet.
Again for example, No. 2619389 Chinese utility model patents of CN of announcing on June 9th, 2004 disclose a kind of fault simulation device of automobile ECU complex control system, this device comprises condition indication circuit and organizes by bistable switching circuit more, the gauge tap circuit, the fault simulation circuit that default fault end is formed, wherein the gauge tap circuit comprises triode and relay, the output terminal correspondence of bistable switching circuit connects gauge tap circuit and condition indication circuit, the normally closed contact of relay is serially connected in the controlling computer and the sensor of automobile ECU complex control system, between the executive component, it is often opened to touch and is serially connected between controlling computer and the default fault end.Identical with the teaching test vehicle of " smart car ", the shortcoming that this fault simulation device exists is: the first, and the number of faults that can simulate setting is very limited; The second, only can be used to be provided with fault, and can not be used for detection failure, make the student often can only observe phenomenon of the failure like this from the surface, and can't be to diagnosing malfunction and analysis.Therefore teaching efficiency is not good.
Summary of the invention
One of the technical problem to be solved in the present invention is, a kind of control device of teaching vehicle is provided, and adopts this control device not only to make teaching vehicle can simulate various vehicle failure, but also can detect the fault that is produced with the diagnostic teaching car by this control device.Therefore, not only more directly perceived, vivid when adopting this control device and teaching vehicle to impart knowledge to students, teaching efficiency is good, and the content of courses is extensive, and is multiple functional, and comparatively speaking, cost reduces greatly.
Another technical matters that the present invention will solve is that a kind of teaching vehicle of using above-mentioned control device is provided.
