- The present work focuses on developing a data-driven forward facing propulsion system model for Chevrolet Bolt 2019 EV vehicle. The model built in the study gives simulated results of the vehicle propulsion system dynamics and latencies when the necessary inputs of the accelerator pedal and brake pedal are known. Vehicle acceleration and braking characteristics are captured and built into the models in the shape of response maps function of vehicle speed and percentage pedal input. With the necessary inputs of APP and BPP, the model predicts the vehicle state in terms of axle torque and speed. The response maps are developed by performing specialized regression testing of the vehicle using New Eagle Drive By Wire system at the American Center of Mobility, (ACM) proving grounds. The model is validated by using track testing data around the ACM proving grounds and using the model to estimate the vehicle speed for various drive cycles containing normal and aggressive drive cycles by giving the inputs of the accelerator pedal and brake pedal recorded from the vehicle CAN channels. The developed model predicted the vehicle velocity within ± 1 m/s for the track test data containing various aggressive and standard driving maneuvers.
