  • Publication number: 20240162835
    Abstract: A system includes a battery configured for providing electrical energy in direct current and a drive unit configured for utilizing electrical energy in alternating current to provide an output torque. The system includes a power inverter configured for receiving the electrical energy in direct current, transforming the electrical energy to alternating current, and providing the electrical energy in alternating current to the drive unit. The power inverter includes a direct current bus bar. The system includes a computerized controller. The controller monitors an environmental temperature of the inverter and monitors a current flow of the electrical energy received by the inverter. The controller determines an estimated temperature of the bus bar based upon the environmental temperature and the current flow and determining an inverter percent available capability based upon the estimated temperature.

  • Publication number: 20240157911
    Abstract: A method of controlling access into a vehicle interior from a vehicle exterior using an access door includes generating a digital key signal via a mobile device in possession of a vehicle user. The method also includes receiving, via a virtual key control module (VKCM), the digital key signal from the mobile device and communicating a signal indicative of the received digital key signal to a vehicle controller. The method additionally includes detecting a presence of the vehicle user external to the vehicle within a predetermined proximity of the access door via an ultrasonic sensing arrangement. The method also includes communicating, via the ultrasonic sensing arrangement, the detected presence of the vehicle user to the vehicle controller. Furthermore, the method includes commanding, via the vehicle controller, a mechanism to release the access door in response to the received digital key signal and the detected presence of the vehicle user.

  • Publication number: 20240162518
    Abstract: In some aspects, a battery module includes a plurality of high energy density-based cells sandwiched between low energy density-based cells provides for a relatively thinner cell barrier between groups of cells, which reduces space required for mitigation solution for thermal runaway propagation (TRP) while maintaining a relatively high range of miles in an electric vehicle per individual charge. In some embodiments, the module includes bus bar and tab configurations on the front and rear portions which enables an efficient connection of components using the above-referenced combination of high and low energy density-based cells for optimal performance.

  • Publication number: 20240157791
    Abstract: A method of controlling a color display screen aboard a motor vehicle includes performing, via a host computer, a color calibration test of a user of the motor vehicle in which the user is subjected to a calibrated set of color-coded test information. The method includes receiving a color perception response of the user to the calibrated set of color-coded test information via the host computer. Additionally, the method includes mapping a reduced visual gamut of the user via the host computer using the color perception response, and then commanding adjustment of user-specific color settings of the motor vehicle using the reduced visual gamut to thereby accommodate a color perception deficiency of the user.

  • Publication number: 20240162796
    Abstract: Aspects of a synchronous electric motor, including a synchronous interior permanent magnet or a synchronous reluctance motor, are disclosed. The outer edges of pockets and magnet pockets, including flux barriers, selectively include one or more notches at the front of the pockets. The use of these notches may redirect flow of the magnetic flux such that overall torque ripple may be reduced without significantly adversely affecting the average torque output of the motor. In some embodiments, various characteristics of the notches may be changed to achieve optimal performance including number, geometry, and location of the notches on select outer edges of the pockets. Another characteristic includes symmetry of the notches or asymmetry, whether in the radial and longitudinal directions of the rotor.

  • Publication number: 20240159197
    Abstract: The concepts described herein relate to a system, method, and/or apparatus for monitoring a NOx sensor that is arranged in an exhaust gas feedstream of an internal combustion engine downstream of an exhaust aftertreatment system to detect a fault related to the NOx sensor. This includes utilizing a catalyst efficiency model to detect occurrence of a fault that may indicate an in-range biased or stuck NOx sensor.

  • Publication number: 20240161339
    Abstract: A method and system for correcting alignment of images received from cameras by estimating camera alignment parameters based on perturbative correction such that corrected alignment parameters satisfy pairwise epipolar constraints as well as global loop closure constraints. The corrected alignment parameters are estimated as a Least-Mean-Square solution to a system of linear equations and an estimation algorithm may be implemented as a part of a Random Sample Consensus criterion estimation for improved robustness. The method and system is fast and efficient and may be implemented in a real-time system.

  • Publication number: 20240157426
    Abstract: A forming tool has an upper portion composed of an upper forming die arranged between a first clamping element and a second clamping element, and a lower portion composed of a lower forming die arranged between a third clamping element and a fourth clamping element. The first clamping element and the third clamping element cooperate to exert a first clamping force on a workpiece; and the second clamping element and the fourth clamping element cooperate to exert a second clamping force on the workpiece. The upper forming die cooperates with the first and second clamping elements and the lower forming die cooperates with the third and fourth clamping elements to exert a lateral force on the workpiece when the first and second clamping forces are being exerted on the workpiece and when a vertical compressive force is being exerted upon the upper forming die and the lower forming die.

  • Publication number: 20240157463
    Abstract: Methods and systems for joining multiple workpieces are provided. In one example, the method includes dispensing adhesive on a first workpiece. A second workpiece is contacted with the adhesive such that the adhesive is disposed between the first and second workpieces. Resistance heating is produced in the first and second workpieces at first processing conditions to partially cure the adhesive and affix the first and second workpieces together to form a partially cured, adhesive-joined workpiece assembly. The partially cured, adhesive-joined workpiece assembly is exposed to heat at second processing conditions to substantially fully cure the adhesive.

  • Patent number: 11984834
    Abstract: A power control system comprises a battery system including N battery packs. A plurality of contactors selectively connects N battery packs of a battery system in a first configuration supplying a first voltage level, a second configuration supplying a second voltage level, and a disconnected configuration. M power inverters connect the battery system to M electric machines, respectively. A controller is configured to determine when to transition between the first configuration and the second configuration. The controller is configured to transition between the first configuration and the second configuration by causing one of a positive torque transient and a negative torque transient to be generated by at least one of the M electric machines, transitioning the battery system from one of the first configuration and the second configuration to the disconnected configuration, and transitioning from the disconnected configuration to the other one of the first configuration and the second configuration.

  • Patent number: 11981207
    Abstract: A method for presenting one or more images to an observer on a reconfigurable electronic display includes prompting the observer to select a portion of the display that is visible to the observer and, if the observer has selected a portion of the display, presenting the images to fit within the selected portion of the display. Subsequent to presenting the images to fit within the selected portion of the display and in response to at least partial obstruction of the observer's view of the images by a visual obstruction, the images are reconfigured to be fully visible to the observer notwithstanding the visual obstruction.
