Problems solved by technology

[0003] Many existing cars are manual transmission (MT) systems. If you want to convert them to automatic transmission systems (AT), the cost is relatively expensive, and not all cars are suitable for modification, especially small-displacement cars, which inherit MT gears. The AMT with the characteristic of mechanical shifting, seems to have a strong and powerful mechanical arm, which transmits power to the wheels
It is not only suitable for large-displacement engines and sports cars, but also can be used for small-displacement cars. It has a good prospect to use AMT system to modify the car with manual transmission (MT) system, but the detection of AMT system Still a big problem, which leaves the security of the AMT system unproven

Embodiment 1

[0026] A method for detecting the function of the clutch CPU of an AMT system, including the wheel speed of the clutch CPU, the detection function of the engine speed and the braking and reversing signal acquisition functions of the clutch CPU;

[0027] The wheel speed and engine speed detection functions of the clutch CPU include the following steps:

[0028] (1) The computer PC issues an instruction to place the checked motherboard in the self-control mode;

[0029] (2) The computer PC issues instructions to control the signal generator to output the waveform value of the specified frequency;

[0030] (3) The output signal of the receiving signal generator of the detected main board is uploaded to the detection board;

[0031] (4) The detection board transmits the signal to the computer PC;

[0032] (5) Repeat steps 2 to 4;

[0033] (6) The computer PC analyzes the results uploaded by the test board and generates a test report;

[0034] The braking and reversing signal a...

Embodiment 2

[0042] The function detection of the above-mentioned AMT system clutch CPU must be detected on the basis of the normal detection of the main serial port communication function of the main CPU, the SPI communication function between the main CPU and the other three driving CPUs, and the EEPROM storage function of the three driving CPUs.

[0043] The above-mentioned signal generator is used in the detection system of the main control board of the automobile AMT system to simulate and generate the automobile engine speed signal and the wheel speed signal.

[0044] Beneficial effects of the present invention: the function detection method of this AMT system clutch CPU provided by the present invention can detect the wheel speed and engine speed detection function of the clutch CPU of the main control board of the automobile AMT system and the braking and reversing signal acquisition functions of the clutch CPU. Conduct detection to reduce the possibility of failure of the main cont...

Abstract

The invention belongs to the field of automobile automatic control technology and specifically relates to an AMT system clutch CPU function detection method, including detecting wheel speed and engine speed detection function of a clutch CPU and brake and reversing signal acquisition function of the clutch CPU. By the AMT system clutch CPU function detection method, wheel speed and engine speed detection function of the clutch CPU of a main control panel of the AMT system and brake and reversing signal acquisition function of the clutch CPU can be detected. Thus, 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 [0001] The invention belongs to the technical field of automobile automatic control, and in particular relates to a function detection method of a clutch CPU of an AMT system. Background technique [0002] Automotive electromechanical automatic transmission (AMT) is an automatic transmission system controlled by a microcomputer on the basis of a dry clutch and a gear transmission. It can determine the best gear according to parameters such as vehicle speed, accelerator, and driver's command, and control the clutch separation and engagement, the shift handle's removal and engagement of the gear lever, and the synchronous adjustment of the engine's throttle opening that were originally completed manually by the driver. Wait for the operation process, and finally realize the manipulation automation of the shifting process. [0003] Many existing cars are manual transmission (MT) systems. If you want to convert them into automatic transmission systems (AT), the ...
