This presentation introduces a model-based approach to developing and calibrating control strategies for hybrid motorcycle powertrains. Using a CAE toolchain combining IGNITE and Simulink, the methodology enables early-stage evaluation of vehicle longitudinal behaviour and powertrain architecture selection. Once the architecture is established a focus is placed on control calibration tasks such as throttle-to-torque mapping and ICE/EM torque blending, which significantly affect drivability under low-speed and transient conditions. Using Model-in-the-Loop (MiL) simulation, the control logic can be iteratively tuned in realistic driving scenarios, allowing engineers to evaluate calibration trade-offs prior to physical testing.
