HIL Simulation Advantage q Development cost reduction: using HIL simulator for both control hardware and software (strategy) development reduces engine dynamometer usage, and hence reduces control strategy development cost. q Short development cycle: control algorithm can be developed, implemented, and validated efficiently in the HIL simulation environment since it does not involved in actual hardware. Study can be done before the hardware is made. q Flexible development environment: powertrain system model can be reconfigured easily in HIL simulation, allowing to study different powertrain system with different configurations. |
