Boosting Transportation Efficiency: The effect of lowpass filtering the speed trajectory

As electric vehicles with some level of autonomy begin to take over the automobile market, optimizing the energy consumption of these vehicles is becoming increasingly important. One promising approach is called  “pulse-and-coast,” which involves a steep acceleration, then a coasting deceleration during which the vehicle does not consume energy. This idea has been largely discarded due to passenger discomfort. However, a low-pass-filtered version of this sawtooth-like velocity curve can reduce acceleration, and create a more comfortable ride while maintaining significant energy efficiency. The purpose of this project is to identify the filters and subsequent waveforms that optimize the balance of comfort and efficiency.
