Dummy Shift Logic

A minimal shift logic implementation that provides the required interface without actual shifting behavior. Used for direct-drive vehicles, single-speed EVs, or testing scenarios.

DCT Gearbox Shift Logic

Shift logic module for Dual-Clutch Transmissions (DCT). Pre-selects the next gear on the alternate shaft for near-instantaneous shifts. Manages clutch engagement, pre-selection strategy, and launch control integration.

Electric Motor Shift Logic

Shift logic for electric motor drivetrains. Manages single or multi-speed EV transmissions, regenerative braking integration, and one-pedal driving mode. Handles the unique torque characteristics of electric motors.
