PACCAR

Positive / Negative Torque Control

The E-Truck Challenge began in late 2023 through a partnership with PACCAR to retrofit a Class 7 Peterbilt truck into an all-electric vehicle over four years. The effort grew to include a broader UW student engagement through a Registered Student Organization (RSO) focused on giving participants hands-on experience with industry components, software, and engineering practices while advancing cleaner transportation. This team contributed to the electrification of the donated truck chassis by developing torque logic using Simulink, CANalyzer, and Raptor, for deployment on the electronic control unit. Prioritizing safety and efficiency, the developed software ensures precise and reliable power delivery to the wheels all while using SAE J1939 standards for easy integration and seamless adaptation.
