Abstract
The invention belongs to the field of automobile automatic control technology and specifically relates to an AMT system's main control panel serial port communication detection method, including first serial port communication detection of a main control panel and second serial port communication detection of the main control panel. By the automobile AMT system's main control panel serial port communication detection method, the main control panel serial port communication function of an automobile AMT system can be detected, the possibility that the main control panel breaks down is minimized, and reliability of the main control panel is raised. Furthermore, possibility of the whole AMT system is higher, security of a car equipped with the AMT system is raised, and car accidents caused by failures of the AMT system are reduced.
Description
Technical field
The invention belongs to automobile automatic control technology field, be specifically related to a kind of AMT systematic master control board serial communication detection method.
Background technology
Automobile electric control mechanical type automatic speed variator (AMT) is to install micro-processor controlled automatic speed-changing system additional on dry clutch and gear-shift mechanism basis.It can be according to the speed of a motor vehicle, throttle, the parameter such as driver-commanded, determine best gear, control clutch separation that former cause driver manually completes and engage, the plucking gear and put into gear and the operating process such as adjusted in concert of the accelerator open degree of engine of shift handle, finally realize the manipulation robotization of shift process.
Existing a lot of car is manual transmission (MT) system, if repack automatic transmission system (AT) into, expense is relatively expensive, and not every car is all applicable to repacking, the automobile of small displacement particularly, and inherited the AMT of MT gear type mechanical speed change feature, and have seemingly strong strong mechanical arm, power is transported to wheel.It is not only suitable for engine and the sports type sport car of large discharge capacity, also can be on automobile with small output volume, adopt AMT system to reequip the automobile of manual transmission (MT) system, there is good prospect, but the detection of AMT system remains a large problem, security of AMT system cannot be verified for this.
Summary of the invention
The object of this invention is to provide AMT systematic master control board serial communication detection method, comprise master control borad first serial communication check and master control borad second serial communication check;
Master control borad first serial communication check, comprises the steps:

(4) computer PC issues the instruction of first serial communication check to check-out console;
(5) check-out console receives instruction, according to instruction, sends detection signal to tested drafting board;
(6) tested drafting board receives instruction, and link order executable operations reply instruction;
(7) check-out console receives and replys instruction, and result is uploaded to computer PC;
(8) repeating step 4～7;
(9) computer PC analysis result, generates examining report;
Master control borad second serial communication check, comprises the steps:
(1) computer PC issues the instruction of second serial communication check to check-out console;
(2) check-out console receives instruction, according to instruction, sends detection signal to tested drafting board;
(3) tested drafting board receives instruction, is placed in automatic control pattern;
(4) checker moves handle, and tested drafting board receives handle position signal by tested drafting board host CPU COM2 mouth;
(5) tested drafting board is uploaded to check-out console by position signalling;
(6) check-out console reception result, and be uploaded to computer PC;
(7) computer PC shows result, and checker and handle position contrast, judge whether normal;
(8) repeating step 1～7;
(9) computer PC analysis result, generates examining report.
Above-mentioned master control borad second serial communication check must be carried out in the situation that master control borad first serial communication check is normal.
Above-mentioned first serial is tested drafting board host CPU COM port or COM device or COM1; Second serial is tested drafting board host CPU COM2 mouth.
Beneficial effect of the present invention: the detection system of this automobile AMT systematic master control board provided by the invention, can detect the master control borad serial communication function of automobile AMT system, reduce the possibility of main control board occurs fault, improve the reliability of master control borad, and then make the possibility of whole AMT system higher, improve the security that AMT system is housed, reduce automobile and occur because the AMT system failure causes the situation that accident occurs
