Description
Technical field
The present invention relates to vehicle electric field, especially a kind of novel automobile electrically-controlled controller and detection method thereof.
Background technology
At present the automobile electronic information product has on average accounted for 1/3rd of automobile total cost, and this ratio also improves continuing, scholarly forecast, and in following 10 years, this ratio will reach 40 percent.Middle-grade car has tens vehicle electronic control unit ECU (Electronic Control Unit) at least, so-called vehicle electronic control unit ECU, in fact be exactly the embedded system of a band single-chip microcomputer, processor, I/O equipment and storer that oneself is arranged, the a certain system of the independent Control of Automobile of energy, for example engine management system EMS (EngineManagement System) controller, anti-lock braking system ABS (Ant-ilock BrakeSystem) controller etc.As for high-grade car, often have tens even up to a hundred vehicle electronic control unit ECU, these vehicle electronic control units ECU links together by the number bus structure, forms the LAN (Local Area Network) of a complexity.Such as, engine management system EMS is made up of microprocessor, various sensor, actuator, by various duties of sensor and parameter, finish exercises for each actuator by microprocessor through sending instruction after calculating, analyze, judging then, make the engine can both be under various working conditions with optimum condition work.
As seen, along with the widespread use of large scale integrated circuit at automotive field, automobile electric control system is huge day by day, complicated, and giving data storing and extracting increases difficulty.When especially testing and keeping in repair, need carry the on-the-spot line of computer, extract the relevant data of electric-control system one to one, as diagnosis sign indicating number and scalar quantity etc., when vehicle fleet size more for a long time, traditional connection mode complicated operation, labour intensity is big, efficient is low.
Summary of the invention
Primary and foremost purpose of the present invention provides a kind of novel automobile electrically-controlled controller, and this controller architecture is simple, is convenient to test and maintenance, has improved work efficiency greatly.
For achieving the above object, the present invention has adopted following technical scheme: a kind of novel automobile electrically-controlled controller, comprise controller, and mobile memory is set in the controller, offering on the controller can be for the slot of mobile memory insertion.
Another object of the present invention is to provide a kind of detection method of novel automobile electrically-controlled controller, this method comprises the step of following order:
(1) will store gauged mobile memory inserts in the slot of offering on the controller;
(2) in test or when maintenance, mobile memory taken out and read the information of mobile memory by PC, if controller breaks down, then store diagnostic message in the mobile memory, otherwise, no diagnostic message.
As shown from the above technical solution, the present invention stores in the mobile memory by the partial information with controller, like this when test or maintenance, directly extract in the slot with the mobile memory slave controller, and read diagnostic message or other information in the mobile memory by PC, and need not to carry the on-the-spot line of computer, extract the relevant data of electric-control system one to one, operating process is simple, efficient is high, greatly reduces labour intensity.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a process flow diagram of the present invention.
Embodiment
A kind of novel automobile electrically-controlled controller, comprise controller, mobile memory 10 is set in the controller, offering on the controller can be for the slot 20 of mobile memory 10 insertions, storer inserts in the slot 20 of controller, matching of the shape of the shape of mobile memory 10, size and slot 20, size, as shown in Figure 1.
In conjunction with Fig. 1, described mobile memory 10 adopts SD card, MiniSD card or USB flash disk etc., the information that stores in the mobile memory 10 is scalar quantity and diagnosis sign indicating number etc., described controller is vehicle electronic control unit ECU, for example engine management system EMS controller, electric booster steering controller ESP, car body controller BCM, anti-lock braking system abs controller, hybrid power electric control system controls device or the like.According to present technology, need be the controller of different engine coupling different models, and these controllers often have only the scalar quantity of software different, software algorithm and hardware components are similar substantially, therefore, correlation parameter data storage such as data that the present invention will change with engine system such as scalar quantity, diagnosis sign indicating number are in mobile memory 10, controller is made general part, be matched with different engines, both reduced the expense expense of design, manufacturing, mould, save cost, also be convenient to maintenance simultaneously.The present invention can not only be applied in the structure of engine control system, also can be applied in automobile other control system such as hybrid power, the power assembly of electric automobile controller.
In conjunction with Fig. 1,2, the present invention is divided into two classes with the program that all vehicle electronic control unit ECU on the vehicle use: a class is every kind of car unique control of each platform program, be called the bottom program, control strategy determines that back bottom program will need not to revise, and programming once gets final product; Another part is the application program that is complementary with the bottom program, comprise diagnosis sign indicating number and scalar quantity etc., these data need be debugged and check repeatedly, and on a mobile memory 10, this mobile memory 10 can be connected on the PC as USB flash disk these data programmings.The present invention can move easily, revise, extracts the data in the electric-control system, need not to carry computer to on-the-spot just can burning program, especially easy to operate in debug phase and batch burning, the efficient height.
Below in conjunction with Fig. 1,2 the present invention is described further.
Insert in the slot of offering on the controller 20 storing gauged mobile memory 10, when test or maintenance, mobile memory 10 is taken out, and read the information of mobile memory 10 by PC, need not to carry PC and connect image data,, then store diagnostic messages such as diagnosis sign indicating number in the mobile memory 10 if controller breaks down to on-the-spot plug wire, otherwise, no diagnostic message.
In sum, core of the present invention is to store in the mobile memory 10 by the partial information with controller, like this when test or maintenance, directly extract in the slot 20 with mobile memory 10 slave controllers, and read diagnostic message or other information in the mobile memory 10 by PC, and need not to carry the on-the-spot line of computer, extract the relevant data of electric-control system one to one, operating process is simple, efficient is high, greatly reduces labour intensity.
