  • Patent number: 10254374
    Abstract: A method for estimating torque control error at an electric machine considers the effects of current sensor error characteristics. Systems and methods can be practiced to determine the maximum sensor error that can be tolerated without causing unacceptable torque error. An example method uses sensor characteristics and machine characteristics to determine current sensing error, current control error, and torque control error. Determining the lowest sensor accuracy required for a desired torque control accuracy can facilitate the use of lower cost sensors in current-feedback controlled electric drive systems without compromising performance. Other applications can include vehicle diagnostics and torque error compensation.

  • Patent number: 10020761
    Abstract: An embedded controller in a vehicle electronics subsystem includes a signal processing circuit used to communicate with an electric machine. The signal processing circuit may be configured to receive an input signal from the electric machine and provide digital output signals to the embedded controller. The digital output signals may include Hall position and rotor position signals. Once the digital output signals are processed by a processor embedded within the controller, the processor may issue a control command to the electric machine. The processor may have memory containing software to make the processor execute the computation of the control command of the electric machine in accordance with a torque command.

  • Patent number: 9372234
    Abstract: Systems, apparatus, and methods detect a current sensor error in an FOC electric machine system. A voltage command is monitored to detect the presence of an ac component that indicates that an error has occurred at a current sensor. For example, a sensor fault detection module can be configured to determine the deviation between an actual voltage command and an ideal voltage command to provide a complex deviation vector. By transforming the deviation vector to a reference frame rotating at the fundamental frequency of the command voltage, a dc component of the positive and negative sequences can be filtered, and their amplitudes determined. Error detection can be based on the total amplitude of the fundamental component, determined by positive and negative component amplitudes. Sensor error detection enables an FOC system to operate with two current sensors, rather than three, and provides a dedicated fault diagnostic for a current sensor.

  • Patent number: 9369071
    Abstract: A discontinuous pulse width modulation technique is used in a controller to control an inverter that converts DC battery power to AC power to operate an electric motor, e.g., in a hybrid electric vehicle. The discontinuous pulse width modulation technique uses only one of the two zero state voltage vectors in its calculations whereas traditional pulse width modulation uses both zero state voltage vectors. The use of a single zero state voltage vector can result in one of a group of switches in the inverter remaining in a constant state during a complete duty cycle while still providing the commanded voltage vector to the electrical motor. As a result losses due to switching can be reduced.

  • Patent number: 9150108
    Abstract: Systems, methods and apparatus are presented to determine high voltage cable connectivity between an inverter module and a remote electric machine. A high frequency (HF) interlock module can be configured to inject a high frequency excitation signal that can be superimposed on inverter drive signals. High frequency current components can be determined and used to determine connectivity status. The sum and difference of positive and negative sequence component values can be compared to predetermined limitations to detect one or more open phases. An example method can include enabling a HF detection strategy under predetermined conditions. In response to an open phase detection a fault flag can be set.

  • Publication number: 20150105651
    Abstract: A method for improving health may include the steps of receiving patient input from a first patient regarding at least one parameter, scanning the first patient for a biomarker using an internal imaging machine, receiving a health plan for the first patient, accessing a database and searching the database for other patients having patient input similar to the first patient, predicting changes in the biomarker based on a patient having input similar to the first patient, and presenting the first patient with the predicted results. Follow-up monitoring may include the steps of receiving internal imaging data as a baseline for a patient undergoing a health plan to improve one or more biomarkers, measuring the patient for one or more biomarkers, estimating the patient's progress by comparing the measurement taken with the baseline internal imaging data, and presenting the patient with the estimated progress.
