In-Vehicle Evaluation of a Rule-based Look Ahead Controller for Mobile Air Conditioning: Impact on Energy Savings

<div class="section abstract"><div class="htmlview paragraph">Energy efficiency in both internal combustion engine (ICE) and electric vehicles (EV) is a strategic advantage of automotive companies. It provides a better user experience that emanates amongst others from the reduction in operation expenses, particularly critical for fleets, and the increase in range. This is especially important in EVs where customers may experience range anxiety.</div><div class="htmlview paragraph">The energetical impact of using the air conditioning system in vehicles is not negligible with power consumptions in the range of kilowatts, even with a stopped vehicle. This becomes particularly important in areas with high temperature and humidity levels where the usage of the air conditioning systems becomes safety factor. In such areas, drivers are effectively forced to use the air conditioning system continuously. Hence, the air conditioning system becomes an ideal choice to deploy control strategies for optimized energy usage.</div><div class="htmlview paragraph">In this paper, we propose and implement a control strategy that allows a significant reduction in energy usage without influencing the comfort or safety of the occupants. This strategy does not rely on complex model predictive controllers and hence it can be easily implemented in production electronic control units minimizing any impact on costs.</div></div>
