Design of an Energy-Efficient Climate Control Algorithm for Electric Cars

A climatisation controller for a car with multiple objectives is developed, implemented and tested in simulations. The design focuses on electric cars and their specific characteristics. In this context the goal has been to fulfil common comfort and safety standards while having a low energy consumption. The main idea of the control in order to achieve this is to use a simplified model predictive control scheme to find the best compromise between those objectives. A special evolutionary algorithm and a simplified system model are developed for this purpose. Another feature of the control design is adaption of disturbance terms in this model based on their estimation. As interface to the hardware a second controller is introduced. The approach has been implemented for the electric car MUTE which is currently developed at the TU Munchen. This implementation was verified to work with the available hardware and tested using a thermal car interior simulation model.
