A method for carrying out mode calibration and automatic testing in an automatic transmission by using the system comprises the following steps:
step one, making a test plan of the slope mode of the automatic transmission for mapping
(1) Compiling a ramp slope simulation model and an accelerator pedal and a brake pedal of the whole vehicle by using matlab in the upper computer;
(2) and burning the ramp slope simulation model compiled by matlab into hardware-in-the-loop test equipment, and analyzing and simulating the intention of a driver by using an accelerator pedal and a brake pedal of the hardware-in-the-loop test equipment under manual control.
Step two, establishing verification test specifications and plans of ramp modes of the automatic transmission
The whole function can be tested according to the requirements, for example: and (3) simulating downhill upshifting, setting an accelerator pedal to be 0, setting a braking system to be 0-100, and observing the change of gear shifting points of a controller of hardware in the loop test equipment on different slopes.
In the invention, the control ramp mode control benchmarking verification test module can realize different gear shifting rules, which are divided into the conditions of ascending gear, descending gear and descending gear, and realizes interface control in the upper computer 1, and drives the hardware-in-loop test equipment 2 to realize simulation of vehicle environment and road condition, and the hardware-in-loop test equipment 2 is connected with the automatic transmission controller 4 by using the signal converter 3.
According to the invention, the ramp mode is programmed in the upper computer 1 to control the calibration test module, so that the calibration difficulty can be simplified, and the calibration personnel can conveniently observe the gear shifting change condition of the automatic transmission.
In the invention, the hardware-in-loop test device 2 can save the benchmarking cost, has no oil consumption and has no pollution to the development of the benchmarking test.
Example (b):
in this embodiment, the upper computer 1 compiles a ramp mode verification test case of the automatic transmission, tests the working conditions in the ring test device 2 through hardware, inputs test data into the automatic transmission controller 4 through the signal converter 3, generates a test report and a test result, and feeds back the test data to the ring test device 2 through the signal converter 3 again to be displayed in the upper computer 1.
As can be seen from fig. 2, the influence of the gradient on the upshift is as follows: during a downhill upshift, the shift point shifted near 0 throttle is the largest, in order to better utilize the transmission to tow the engine backwards, when the throttle is not near 0, at which time the driver will want to go downhill quickly, seeing that the shift point again moves back to the level shift point. It can be seen that the gradient and the shift point progression are positively correlated.
As can be seen in fig. 3: in a downhill upshift, the shift point also shifts, depending on the gradient, in order to ensure a better driving force of the vehicle on the hill.
As can be seen in fig. 4: in the upslope upshifting process, in order to ensure the dynamic property of the whole vehicle, the upshifting point is delayed along with the rising of the gradient. In the upslope downshifting process, in order to better prepare for next upslope upshifting and provide better power responsiveness in advance, an upslope downshifting point can move along with an upslope upshifting point.
