Latest Patents

Stefan Grubic holds a patent for the "Mitigation of vehicle vibrations induced by drive-line oscillations." This invention involves an electric motor controller designed to reduce vehicle vibrations caused by drive-line oscillations. The motor speed is measured at the output of the motor, separate from any measurements of drive shaft or wheel speed. Bandpass filtering is applied to the measured motor speed, based on the natural frequency of the drive shaft. This filtering detects drive-line induced oscillations of the motor speed. A controller utilizes the detected oscillations to generate an oscillation control output, which is subject to limiting. An oscillation mitigation torque signal corresponding to the control output is added to a torque command for the desired motor speed, effectively adjusting for the oscillations. The adjusted torque command is then used to control the motor, resulting in a significant reduction in the oscillation of the motor's speed. Stefan has 1 patent to his name.
