Detailed description of the invention
Below the present invention is described further:
In the present invention, our object is only the variation tendency needing user to know 4 wheel driven front and back wheel moment of torsion intuitively, and trailing wheel moment of torsion involvement level roughly, does not need the accurate size of front and back wheel moment of torsion.Realize the program, replace formula 1 and formula 2 with relevant signal, front wheel torque " engine output torque T
tq" approximate representation, trailing wheel moment of torsion " torque management device output torque expected value T
e" approximate representation, the variation tendency of these two signals is consistent with the variation tendency of formula 1 and formula 2, can realize the program.
Concrete improvement project is:
Cancel the 4 wheel driven background warning light in instrument, avoid showing with the moment of torsion on instrument panel 8 repeating.Use " engine output torque Ttq " that engine controller 6 sends and " torque management device output torque expected value Te " two signals that 4 wheel driven controller 5 sends, by CAN platform, these two signals are sent to instrument signal processing module 7, drive the dynamic column scale map on instrument liquid crystal display 4, dynamic column scale map changes accordingly along with the change of " engine output torque Ttq " and " torque management device output torque expected value Te " signal, also just achieve in real time, dynamically show the roughly allocation proportion of front and back wheel moment of torsion, and the involvement level of four-wheel drive system.
