  • Patent number: 11416663
    Abstract: A system for controlling a motor with a plurality of motor control functions including at least a current control loop and a velocity control loop. The system includes one of a hybrid Digital Signal Processor (DSP)-Field Programmable Gate Array (FPGA) architecture having an integral DSP and an integral FPGA or a System on a Chip (SoC) architecture having a Microcontroller Sub-System (MSS) and an FPGA fabric. The current control loop function is assigned to the integral FPGA for the hybrid DSP-FPGA architecture, and at least the velocity control loop function is assigned to the DSP the hybrid DSP-FPGA architecture. Alternatively, the current control loop function is assigned the FPGA fabric of the SoC architecture, and at least the velocity control loop function is assigned to the MSS of the SoC architecture.

  • Patent number: 11087911
    Abstract: Provided are embodiments for operating an autonomous mode change circuit for solenoid drivers. The embodiments include initiating an operation of a solenoid, and receiving a command to control the operation of the solenoid. The embodiments also include controlling, by a drive circuit, a switch coupled to the solenoid based at least in part on the command, and detecting at least one of a current or voltage of the solenoid, and subsequently controlling the operation of the solenoid based at least in part on the detection.

  • Patent number: 10830810
    Abstract: Embodiments herein relate to a sensor fault measurement system. The system includes a sensor having a primary winding, a first secondary winding and a second secondary winding and a wiring harness operably connected to the primary winding, first secondary winding and second secondary winding of the sensor. The system also includes a controller operably connected to the wiring harness. The controller includes a bias network configured to apply a common mode DC voltage bias of opposite sign to the first sensor output and the second sensor output respectively, and a fault sense circuit configured to monitor the DC voltage bias on first sensor output and the DC voltage bias on second sensor output, and identify a sensor fault if at least one of the DC voltage bias on first sensor output and the DC voltage bias second sensor output is impacted beyond a selected threshold.
