Abstract: This document describes techniques and systems for vehicle localization based on radar detections in garages and other GNSS denial environments. In some examples, a system includes a processor and computer-readable storage media comprising instructions that, when executed, cause the system to obtain structure data regarding a GNSS denial environment and generate, from the structure data, radar localization landmarks. The radar localization landmarks include edges or corners of the GNSS denial environment. The instructions also cause the processor to generate polylines along or between the radar localization landmarks to generate a radar occupancy grid. The instructions further cause the processor to receive radar detections from one or more radar sensors and obtain a vehicle pose within the radar occupancy grid to localize the vehicle within the GNSS denial environment. In this way, the system can provide highly accurate vehicle localization in GNSS denial environments in a cost-effective manner.

Abstract: The electrical connector comprises at least one contact terminal, a printed circuit board on which at least one thermal sensor is mounted to monitor the temperature of the at least one contact terminal, at least one thermal conductive pad that includes at least one first thermal contact surface in direct engagement with the at least one contact terminal, and a second thermal contact surface in direct engagement with the at least one thermal sensor, to transfer heat from the at least one contact terminal to the at least one thermal sensor, and a support device for the at least one thermal conductive pad. The at least one thermal conductive pad is compressed between the support device and the printed circuit board by a force of compression causing the at least one first thermal contact surface to press against the at least one contact terminal and the second thermal contact surface to deform on the thermal sensor covering the thermal sensor.

Abstract: Electrical connector comprising a detection device for detecting potential overheating, which comprises an electrically conductive element and an electrically insulating element inserted between the electrically conductive element and a low-voltage line. The electrically conductive element exerts an elastic force on the insulating element. For example, the electrically conductive element is a spring. In the event of overheating, the insulating element deforms under the pressure of the electrically conductive element and enables an electrical connection between two low-voltage lines. The overheating is detected as a consequence of the electrical design of this connection between the low-voltage lines.

Abstract: The techniques and systems herein enable interior vehicle alerting based on an object of interest and an environment of a host vehicle. Specifically, an object of interest and an environment proximate a host vehicle is determined. It is then determined that an alert level of the environment in relation to the object of interest meets a notification threshold. Responsive to determining that the alert level meets the notification threshold, a notification based on the alert level is then output that causes a vehicle system of the host vehicle to provide an interior alert to a driver of the host vehicle. By doing so, the system can effectively notify the driver that appropriate action may be applicable (e.g., stopping, accelerating, or steering the host vehicle), which may improve safety, improve traffic flow, and/or mitigate vexation of persons proximate the host vehicle.

Abstract: A computer implemented method for determining a representative input data set for post-training quantization of artificial neural networks comprises: acquiring an input data set; processing the input data set to extract one or more parameters associated with the input data set; setting clipping limits comprising a lower clipping limit and an upper clipping limit; adapting the upper and lower clipping limits by computing (656) a quantization error based on a numerical difference between the input data set and a quantized and a dequantized input data set, wherein the error is computed based on an error metric which is based on user input; and determining a representative input data set as a subset of the input data set whose elements fit within the clipping limits; wherein the representative input data set is to be used for quantization calibration of the post-training quantization.

Abstract: This document describes techniques and systems for asymmetrical frequency-division multiplexing (FDM) for radar systems. In some examples, a radar system includes multiple transmitters, multiple receivers, multiple polyphase shifters, and a processor. The transmitters can transmit electromagnetic (EM) signals in an FDM scheme. The receivers can receive EM signals reflected by one or more objects that include multiple channels. The polyphase shifters can introduce at least four potential phase shifts. The processor can control the polyphase shifters to introduce phase shifts asymmetrically spaced in a frequency spectrum. The processor can determine, using residue estimation and subtraction, potential detections of the objects. In this way, the described asymmetrical FDM for radar systems can support many simultaneous MIMO channels, increase the dynamic range of the radar system, resolve Doppler ambiguities, and provide an efficient processing scheme.
