  • Patent number: 12122248
    Abstract: Presented are control systems for operating dual-independent drive unit (DIDU) powertrains, methods for making/operating such systems, and electric-drive vehicles with fault management and mitigation for DIDU axles. A method of operating a motor vehicle with a DIDU axle includes monitoring first and second drive units (DU) that are independently operable to drive respective road wheels via respective axle shafts of the DIDU axle. A vehicle controller receives an indication of a fault condition in the first DU from a fault sensing module and responsively determines a fault type for the fault condition. The controller ascertains the vehicle's current speed and determines a respective torque limit for each of the DIDU drive units based on the fault type and current vehicle speed. Torque output of the first DU is concomitantly constrained to a first torque limit while torque output of the second DU is constrained to a second torque limit.

  • Patent number: 12122425
    Abstract: Vehicles and related systems and methods are provided for controlling a vehicle in an autonomous operating mode. One method involves identifying one or more avoidance zones in a vicinity of the vehicle, determining a deadline for completing a lateral maneuver to avoid a priority avoidance zone of the one or more avoidance zones, obtaining an initial reference lateral trajectory for the lateral maneuver based at least in part on the deadline, autonomously operating one or more actuators onboard the vehicle in accordance with the initial reference lateral trajectory, and thereafter obtaining one or more updated reference lateral trajectories for the vehicle, wherein the one or more actuators onboard the vehicle are autonomously operated in accordance with the one or more updated reference lateral trajectories in lieu of the initial reference lateral trajectory.

  • Patent number: 12126293
    Abstract: A control system for a rotary electric machine includes an inverter including a plurality of power switches, a heat exchanger, first temperature sensors arranged to monitor the power switches, a second temperature sensor arranged to monitor the heat exchanger, and a controller. An expected power loss is determined based upon electric current, switching functions, and electrical characteristics of the power switches. A plurality of power capacity terms are determined based upon the expected power loss in the inverter, the temperatures of the power switches, and the temperature of the heat exchanger. The inverter is controlled based upon the aforementioned power capacities.

  • Patent number: 12126897
    Abstract: A system for bandwidth saving for wireless cameras using motion vectors includes wireless cameras disposed within the vehicle, and capturing input image data. A control module, having a processor, memory, and input/output (I/O) ports, executes control logic stored in memory. A first control logic receives, real-time input image data from the cameras. A second control logic processes the input image data to maintain (Wi-Fi) bandwidth utilization within the vehicle below a predetermined threshold and maintains and maximizes real-time image data streaming quality through semantic segmentation and background memorization. A third control logic generates an output including background and foreground image portions. The output is transmitted to a human-machine interface (HMI) within the vehicle and periodically replaces the background portion with a cached background scene that is transmitted to the HMI.

  • Patent number: 12124335
    Abstract: A fault tolerant distributed computing system includes a communication link and a plurality of nodes in electronic communication with one another by the communication link. Each node executes at least one node-specific application, includes a standby database that stores a standby copy corresponding to one of the node-specific applications executed by one of the remaining nodes that are part of the distributed computing system, and includes a spare computational capacity sufficient to execute at least one standby copy of one of the node-specific applications stored in the standby database. In response to determining a specific node is non-operational, the remaining nodes execute all the standby copies of the one or more node-specific applications that were previously executed by the specific node that is now non-operational.
