DCT Controller

Dual clutch transmission controller

  • Library:
  • Powertrain Blockset / Transmission / Transmission Controllers

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.

NA
CltchACmd

Clutch pressure command for odd-numbered gears, between 0 and 1

NA
CltchBCmd

Clutch pressure command for even-numbered gears, between 0 and 1

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

expand all

Initial gear to engage, Go.

Time required to engage and disengage the clutch during shift events, tc, in s.

Time required for gear selection and synchronization, ts, in s.

Sample period, dt, in s.

Selecting this parameter initially locks the clutch.

Selecting this parameter initially locks the synchronizer.
