  • Patent number: 12119764
    Abstract: Systems and methods for estimating input current are provided, particularly when input currents are applied to an electric motor of a motor system. An Electric Control Unit (ECU), according to one implementation, is configured to control the motor system. The ECU is configured to store computer logic having instructions that, when executed, cause one or more processing devices to obtain a duty cycle parameter at an output of the ECU. The duty cycle parameter, for example, relates to control actions enforced on one or more switches of a power electronics circuit of the motor system. Based on the duty cycle parameter, the instructions further cause the one or more processing devices to estimate an input current provided to the electric motor of the motor system. A more accurate input current estimation may thereby be used to better estimate torque.

  • Publication number: 20240297607
    Abstract: Systems and methods for controlling one or more inverters in response to detecting a desaturation (DESAT) fault are disclosed herein. A DESAT fault of an inverter coupled to a motor is detected. In response to detecting the DESAT fault, all driving switches of the inverter are instructed to open. The driving switch that failed and a type of failure are determined based on current of the motor during a predetermined time period after instructing all of the driving switches to open, and the remaining driving switches are controlled based on which switch failed and the type of failure.

  • Patent number: 12057732
    Abstract: High voltage discharge is provided. A system can include an electric motor of an electric vehicle electrically connected to a capacitor. A switching component can be connected with and intermediary to the electric motor and the capacitor. A controller can cause the switching component to enter a first state to cause the electric motor to convert electrical power of the capacitor to mechanical power to propel the electric vehicle, or convert mechanical power from a drive system of the electric vehicle to electrical power to charge the capacitor. The controller can cause the switching component to enter, in response to detection by the controller of an indication to discharge the capacitor, a second state to isolate the electric motor from the capacitor.

  • Patent number: 11958364
    Abstract: A torque security system for a vehicle is provided. The system receives a signal from a sensor coupled to a motor shaft of an electric motor and determines an acceleration of the electric motor, based on the signal from the sensor that indicates an amount of rotation of the motor shaft. The system determines an internal torque between the motor shaft and an input gear coupled to the motor shaft, based on the acceleration of the electric motor and an inertia of the electric motor and a gearbox. The powertrain of the vehicle comprises the gearbox and the electric motor, and the input gear couples the electric motor to the gearbox. The system determines whether the internal torque exceeds a threshold torque, and in response to determining that the internal torque exceeds the threshold torque, the system reduces power output to the electric motor. The system also diagnoses the health of the gearbox.

  • Patent number: 11870352
    Abstract: Systems and methods for controlling a dual active bridge converter are disclosed herein. An output voltage of a dual active bridge converter is sensed. Based at least in part on the output voltage, a target intra-bridge phase shift amount between two bridges of the dual active bridge converter is computed.

  • Patent number: 11707992
    Abstract: A system is configured to manage motor engagement in a vehicle by determining to engage a disengaged motor shaft with a drivetrain, and in response, activating a feedback controller based on a speed of the motor shaft and activating a feedforward controller. The system determines at least one metric for modifying an output of the feedforward controller. The at least one metric is based on the speed of the motor shaft and the desired speed, and may be applied as a gain to the output of the feedforward controller. The system generates a command based on the feedback controller, the feedforward controller, and the at least one metric, and causes the motor shaft and the drivetrain to be engaged based on the speed of the motor shaft and the desired speed. The system nulls output of the feedforward controller as the speed of the motor shaft approaches the desired speed.
