Real-time torque corresponding to the pressure of device.
Specifically, the actual pressure for acting on clutch follows order pressure, the pressure for acting on clutch is monitored
Power changing value is in setting range, that is, the actual pressure for acting on the clutch follows order pressure to reach stable state, pressure
Power changing value is in setting range, and pressure determines the real-time torque of driving motor again after no longer floating.Optionally, increase every time
After the pressure for adding preset step-length, the first preset duration is waited to calculate real-time torque again later；Increase the pressure of preset step-length every time
Afterwards, it waits the second preset duration to carry out pressure next time again later to be incremented by.Wherein, the second preset duration is greater than or equal to described the
One preset duration, the first preset duration need to guarantee that actual pressure follows order pressure to reach stable state, to reserve abundance
Time measure stable and accurate actual pressure.
Whether S250, the real-time torque meet the preset condition, if so, S260 is thened follow the steps, if it is not, then returning
Step S230 continues the pressure for increasing preset step-length to the clutch.
S260, the pressure value of clutch is acted on as half hitch chalaza information when real-time torque is met preset condition.
Specifically, when change in torque value reaches preset threshold, using the pressure value for acting on clutch at this time as half
Binding site.For example, when change in torque value reaches 10NM, using pressure value at this time as half hitch chalaza.
The following are the specific descriptions of the realization process to automatic transmission half hitch chalaza test method:
