Description
The DCT Controller block implements a dual clutch transmission (DCT) 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.
Examples
Build Conventional Vehicle Model
Build a vehicle with an internal combustion engine using the conventional vehicle reference application.
Ports
Inputs
Gear number request, Greq.
Output
Bus signal containing these block calculations.
Signal | Description | Variable |
---|---|---|
GearReq | Gear number request | Greq |
GearEngd | Nominal gear commanded by the controller | Go |
GearEffct | Effective gear | NA |
CltchACmd | Clutch pressure command for odd-numbered gears, between | NA |
CltchBCmd | Clutch pressure command for even-numbered gears, between | NA |
Nominal gear for shifting. The Dual Clutch Transmission block uses this signal for the smooth application of inertial, efficiency, gear ratio, and damping parameters.
Clutch pressure command for odd-numbered gears, between
0
and 1
.
Clutch pressure command for even-numbered gears, between
0
and 1
.
Parameters
Time required to engage and disengage the clutch during shift events, tc, in s.
Programmatic Use
To set the block parameter value programmatically, use
the set_param
