Publication number: 20240092190Abstract: Techniques control a utility vehicle. Such techniques involve storing electric power in a lithium battery of the utility vehicle. Such techniques further involve operating a motor controller of the utility vehicle in a normal mode in which the motor controller provides electric power from a lithium battery of the utility vehicle to an electric motor of the utility vehicle to turn one or more ground engaging members of the utility vehicle. Such techniques further involve, after operating the motor controller in the normal operating mode, operating the motor controller in a walkaway mode in which the motor controller configures the electric motor to provide braking torque.Type: ApplicationFiled: November 27, 2023Publication date: March 21, 2024Inventors: Arthur James Harvey, Norman R. Padgett, John Ledden, Robert Charles Bradley, Patrick Dwaine Warden
