Abstract
Optimized control algorithms for a vehicle automatic climate control system (ACCS) are developed using math-based models of the vehicle, the ACCS and a vehicle occupant. The models are cross-coupled in closed-loop fashion with feedback from both vehicle systems and occupant. A first feedback loop including the vehicle and the ACCS, simulates how the ACCS interacts with the cabin environment; and a second feedback loop including the vehicle, the ACCS and the occupant, simulates how the occupant will adjust the ACCS to optimize comfort. When the system arrives at a control algorithm that satisfies control objectives and optimizes occupant comfort, an auto-code generation tool is used to create program code directly from the control model, which may be downloaded into a test vehicle for final system confirmation and calibration.
