System Architecture & Signal Flow
Within the DTCC901B traction control architecture, the DCC2390A-3EST49-116-DTCC901B occupies the drive control layer:
- Upstream: Receives speed/torque setpoints from the Vehicle Control Unit (VCU) via MVB or CAN vehicle bus
- Processing: Executes PWM modulation algorithms, slip control, and regenerative braking logic
- Downstream: Outputs gate drive signals to the IGBT traction inverter power stage
- Feedback Loop: Processes motor current sensors, resolver/encoder feedback, and DC-link voltage for closed-loop vector control
- Diagnostics: Reports fault codes and operational telemetry back to VCU and maintenance terminals
