Abstract
The invention discloses a kind of automobile with fault self-diagnosis, including the controller respectively running part for controlling automobile, it is characterised in that: also include that diagnostor and operation part ruuning situation each to automobile carry out the data acquisition unit of data acquisition；Described diagnostor obtains controller simultaneously and is sent to parameter and the data of data acquisition unit collection of each operation part, and contrast two data the fault of each operation part is judged, it is set up data acquisition unit and is acquired each service data situation running part of automobile, qualitative data and the actual operating data of each operation part that diagnostor sends according to controller are compared, and realize autodiagnosis to judge fault.
Description
Technical field
The present invention relates to automotive field, in particular it relates to a kind of automobile with fault self-diagnosis.
Background technology
Along with the development of auto technology, automatization's electronic control technology is made in maintenance process in the manufacture of new automobile
With, novel automobile have employed substantial amounts of electronic control unit, and maintenance and the maintenance of automobile are no longer simple mechanically actuateds, and
It is increasingly to rely on professional tool electronic, computerized for counsel.The auto repair in past is based on repair of machine and part reparation,
Modern Vehicle Repair is then driven in the diagnostic techniques being diagnosed as core with Mechatronic Systems.In order in response to new trend, how realize vapour
The self-diagnosis of trouble of car has Research Significance and is necessary very much.
Summary of the invention
The present invention is to solve that above-mentioned technical problem provides a kind of automobile with fault self-diagnosis.
The present invention solves the problems referred to above and be the technical scheme is that
A kind of automobile with fault self-diagnosis, including the controller respectively running part for controlling automobile, it is characterised in that: also
The data acquisition unit of data acquisition is carried out including diagnostor and operation part ruuning situation each to automobile；
Described diagnostor obtains controller simultaneously and is sent to parameter and the data of data acquisition unit collection of each operation part, and
Contrast two data the fault of each operation part is judged.
Automobile is when normally travelling, and controller can send operational order to each operation part, and data acquisition unit is to respectively
Run part actual operating data be acquired after feed back to controller, the qualitative data that diagnostor sends according to controller and
Each actual operating data running part is compared, to judge fault, to remind the automobile of fault to arrive repairing in time
Factory keeps in repair.This programme uses two microcontrollers, due to automobile in the process of moving, the controller data amount of automobile self
Greatly, and breakdown judge relates to multilevel iudge process, and this process needs to expend substantial amounts of internal memory and running space, if directly using vapour
The controller of car self, then big to the load that controller brings so that automobile self-operating is affected safely, therefore arrange two
Microcontroller, utilizes diagnostor individually to judge vehicle failure, strengthens the safety of automobilism.
As preferably, described diagnostor is also associated with wireless receiving module, display device and alarm device.
As preferably, described data acquisition unit includes engine speed harvester.
As preferably, described data acquisition unit includes speed data collection device.
As preferably, described data acquisition unit includes device for monitoring tyre pressure.
To sum up, the invention has the beneficial effects as follows:
1, the present invention sets up the data acquisition unit each service data feelings running part to automobile on the basis of existing technology
Condition is acquired, and qualitative data and the actual operating data of each operation part that diagnostor sends according to controller are compared,
Autodiagnosis is realized so that fault to be judged.
2, the present invention uses diagnostor to judge fault, is conducive to strengthening the safety of running car.
Detailed description of the invention
Below in conjunction with embodiment, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that institute
The embodiment described is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, this
The every other embodiment that field those of ordinary skill is obtained under not making creative work premise, broadly falls into the present invention
The scope of protection.
Embodiment 1:
A kind of automobile with fault self-diagnosis, including the controller respectively running part for controlling automobile, it is characterised in that: also
The data acquisition unit of data acquisition is carried out including diagnostor and operation part ruuning situation each to automobile；
Described diagnostor obtains controller simultaneously and is sent to parameter and the data of data acquisition unit collection of each operation part, and
Contrast two data the fault of each operation part is judged.Automobile is when normally travelling, and controller can be to each operation part
Sending operational order, data acquisition unit feeds back to controller to after being acquired the actual operating data of each operation part,
Qualitative data and the actual operating data of each operation part that diagnostor sends according to controller are compared, to carry out fault
Judge, to remind the automobile of fault to keep in repair to repair shop in time.
Wireless receiving module, display device and alarm device it is also associated with on described diagnostor.
Described data acquisition unit includes engine speed harvester.
Described data acquisition unit includes speed data collection device.
Described data acquisition unit includes device for monitoring tyre pressure.
As it has been described above, the present invention can preferably be realized.
