  • Patent number: 12128924
    Abstract: A method for efficient autonomous driving planning includes receiving a current driving-scene data and a predicted driving-scene data. The current driving-scene data is indicative of a current driving scene around a host vehicle. The predicted driving-scene data is indicative of a predicted driving scene around the host vehicle. The predicted driving scene around the host vehicle is different from the current driving scene around the host vehicle. The method further includes converting the current driving-scene data and the predicted driving-scene data into a first scene-graph and a second scene-graph, respectively. The method further includes determining a plurality of scene change metrics using the first scene-graph and the second scene-graph. The method further includes selecting between a first trajectory planning process and a second trajectory planning process based on the plurality of scene change metrics.

  • Patent number: 12132010
    Abstract: Presented are metal-coated, polymer-encapsulated power semiconductor modules, methods for making/using such power modules, and vehicles with traction power inverters containing such power modules. A power electronics assembly includes one or more power semiconductor modules packaged inside an assembly housing. Each power module includes a substrate, a semiconductor device mounted on the substrate, a polymeric encapsulant encasing therein the substrate and semiconductor device, and an electrical lead connected to the semiconductor device and projecting from the polymeric encapsulant. A metallic or ceramic coating is applied to select sections of the polymeric encapsulant's exposed exterior surface. The metallic/ceramic coating may be a single metallic layer that covers substantially all of the exposed surface area of the polymeric encapsulant's exterior surface. An optional hydrophobic polymer layer, passivated layer, and/or oxidized layer may cover the exterior surface of this metallic layer.

  • Patent number: 12128975
    Abstract: A partially assembled vehicle that autonomously completes its own assembly, including a chassis, wheels that are rotationally coupled to the chassis, a drive system mounted on the chassis and in operational communication with the wheels, a navigation system, a central platform controller, and a position determining system. Added thereto is a safety sensor guidance system and a controller circuit programmed to begin a temporary takeover of the central platform controller, responsive to an external fleet control. The temporary takeover including the steps of identifying a plurality of assembly stations that the partially assembled vehicle must visit to complete its own assembly; constructing a sequence in which to visit each of the plurality of assembly stations; and commanding the drive system to propel and steer the partially assembled vehicle through the sequence of the plurality of assembly stations, responsive to sensor input from the safety sensor guidance system.

  • Patent number: 12130390
    Abstract: A LIDAR-to-vehicle alignment system includes a memory and alignment and autonomous driving modules. The memory stores points of data provided based on an output of one or more LIDAR sensors and localization data. The alignment module performs an alignment process including: based on the localization data; determining whether a host vehicle is turning; in response to the host vehicle turning; selecting a portion of the points of data; aggregating the selected portion to provide aggregated data; selecting targets based on the aggregated data; and based on the selected targets, iteratively reducing a loss value of a loss function to provide a resultant LIDAR-to-vehicle transformation matrix. The autonomous driving module: based on the resultant LIDAR-to-vehicle transformation matrix, converts at least the selected portion to at least one of vehicle coordinates or world coordinates to provide resultant data; and performs one or more autonomous driving operations based on the resultant data.

  • Patent number: 12128735
    Abstract: A system for detecting external leaks in a cabin of a vehicle includes sensors and onboard vehicle controls disposed on the vehicle. Control modules of the system have processors, memory, and input/output (I/O) ports. The I/O ports communicate with the sensors and onboard vehicle controls. The control modules execute program code portions stored memory. The program code portions include first and second algorithm portions. The first algorithm portion receives data from the sensors and controls and determines that the data from the sensors and controls meets initialization threshold values. When the data from the sensors and controls meets the threshold values, the second algorithm portion generates a cabin leak detection output including: a first output, a second output, or a third output. The first output indicates a large leak, the second output indicates no leak, and the third output indicates that a small leak has been detected.

  • Patent number: 12128826
    Abstract: A multi-directional viewing camera system for a motor vehicle including a vehicle body defining an interior compartment and a body panel having an exterior surface and an interior surface facing the interior compartment. The camera system includes a mirror module for mounting to the body panel exterior surface. The mirror module is configured to capture and transmit incident light from at least one field of view (FOV) and has a polarizing beam splitter configured to reflect an s-polarized component and transmit a p-polarized component of the incident light in a visible spectral range. The camera system also includes a camera module having a video camera for mounting to the body panel interior surface. The camera module is configured to receive from the mirror module the s-polarized or the p-polarized component of the incident light and selectively display at least one FOV within the interior compartment.

  • Patent number: 12128762
    Abstract: A chassis control system of a vehicle includes: a first torque source providing torque to a first axle of the vehicle; a second torque source providing torque to a second axle of the vehicle independently of the first torque source; and a vehicle control module controlling the first and second torque sources to transition between a torque redistribution and torque limit control modes based on a wheel torque redistribution threshold, a wheel torque limit of the first axle and/or second axle, and a torque limit of one of the first and second torque sources. The torque redistribution mode refers to when torque is being selectively provided to the first axle by the first torque source and to the second axle by the second torque source. The torque limit control mode refers to when torque to at least one of first axle and the second axle is limited.
