A/C Energy Management and Vehicle Cabin Thermal Comfort Control

This is the authors' abstract. We don't add key points for this paper.

This correspondence paper introduces a novel multi-objective controller, which regulates A/C system operation in a tradeoff between vehicle cabin comfort and fuel consumption for a conventional vehicle with internal combustion engine. The controller has been developed and tested in a simulated environment, where an energy-based model of the A/C system is combined with a thermal dynamic model of the cabin, which considers heat transfer to the environment. The control algorithm proposed herein is compared with two widely used control techniques in the industry, respectively the thermostat and PI control, under different driving cycles. This novel method is implementable in real-time, and simulation results show a reduction of up to 2% in A/C system fuel consumption compared to existing methods with similar thermal performance.
