Automated manual transmission controller with clutch open, close, and synchronization timing
Powertrain Blockset / Transmission / Transmission Controllers
The AMT Controller block implements an automated manual transmission (AMT) controller. You can specify the clutch open, close, and synchronization timing parameters. The block determines the clutch commands using integrator-based timers and latching logic that is based on the specified timing parameters and gear request.
GearReq— Gear number to engage
Gear number request, Greq.
Info— Bus signal
Bus signal containing these block calculations.
Gear number request
Nominal gear commanded by the controller
Clutch pressure command for gears, between
GearEffct— Effective gear for shifting
Effective gear for shifting. The block uses this signal for the smooth application of inertial, efficiency, gear ratio, and damping parameters.
Cltch— Command for clutch pressure
Clutch pressure command, between
Initial gear, G_o— Engaged gear
Initial gear to engage, Go.
Clutch actuation time, tc— Time
Time required to engage and disengage the clutch during shift events, tc, in s.
Synchronizer time, ts— Time
Time required for gear selection and synchronization, ts, in s.
Sample period, dt— Time
Sample period, dt, in s.
Clutch initially locked— Select to initially lock clutch
Selecting this parameter initially locks the clutch.
Synchronizer initially locked— Select to initially lock synchronizer
Selecting this parameter initially locks the synchronizer.
