Abstract: A detection system includes a radar-unit and a controller-circuit. The radar-unit is configured to detect objects proximate a host-vehicle. The controller-circuit is in communication with the radar-unit and is configured to determine a detection-distribution based on the radar-unit. The detection-distribution is characterized by a longitudinal-distribution of zero-range-rate detections associated with a trailer towed by the host-vehicle. The controller-circuit is further configured to determine a trailer-classification based on a comparison of the detection-distribution and longitudinal-distribution-models stored in the controller-circuit. The trailer-classification is indicative of a dimension of the trailer. The controller-circuit determines a trailer-length of the trailer based on the detection-distribution and the trailer-classification.

Abstract: This document describes change detection criteria for updating sensor-based maps. Based on an indication that a registered object is detected near a vehicle, a processor determines differences between features of the registered object and features of a sensor-based reference map. A machine-learned model is trained using self-supervised learning to identify change detections from inputs. This model is executed to determine whether the differences satisfy change detection criteria for updating the sensor-based reference map. If the change detection criteria is satisfied, the processor causes the sensor-based reference map to be updated to reduce the differences, which enables the vehicle to safely operate in an autonomous mode using the updated reference map for navigating the vehicle in proximity to the coordinate location of the registered object.

Abstract: Techniques and apparatuses are described that implement height-estimation of objects using radar. In particular, a radar system, which is mounted to a moving platform, receives reflection signals that represent versions of a radar signal that are reflected off of objects. The radar system generates a range-elevation map based on raw data from the reflection signals, identifies an elevation bin and a range bin in the range-elevation map that corresponds to a selected object, and calculates a height for the selected object based on the range and elevation bins. The radar system then calculates a de-noised height for the selected object based on one or more previously calculated heights for the selected object. In this way, the radar system can determine accurate heights of objects at sufficiently long ranges for evasive action.

Abstract: This document describes techniques and systems for a road-perception system to estimate a belief and plausibility of lanes in a road model. The road-perception system models lanes of a road using basis bands to represent lane sections. The basis bands comprise points representing a polyline with a width at each point. The use of basis bands results in lower-computational requirements and a more stable road model than grid-based representations of a driving environment. The road-perception system also determines a belief mass associated with the lane sections. The road-perception system then computes, using the belief masses, a belief parameter and a plausibility parameter associated with proposed lanes of the road model. In this way, the described techniques and systems can provide an accurate and reliable road model and quantify uncertainty therein.

Abstract: A switching circuit has a primary MOSFET switch connected between first and second terminals that are connected to a power line and a load represented as a resistance and inductance. The primary switch is operable by primary control commands to assume a conductive or non-conductive state. Four protection branches are connected in parallel with the primary switch, each having a series connected resistive element and a secondary MOSFET switch operable by branch control commands received at branch command terminals to assume a conductive or non-conductive state. A timing circuit applies branch turn off control commands in sequence to the branch command terminals, each delayed by a different predetermined time interval relative to when a primary turn off control command is applied to the primary switch.

Abstract: Waveguide assemblies are described that utilize a surface-mount waveguide for vertical transitions of a printed circuit board (PCB). The surface-mount waveguide enables low transmission-loss (e.g., increased return-loss bandwidth) by utilizing a waveguide cavity positioned over a plated slot to efficiently transfer electromagnetic energy from one side of the PCB to another side. The waveguide cavity is designed to excite two resonant peaks of the EM energy to reduce a return-loss of power and increase power delivered to an antenna while supporting a high bandwidth of EM energy. Furthermore, the surface-mount waveguide does not require precise fabrication often required for vertical transitions, allowing the surface-mount waveguide to be compatible with low-cost PCB materials (e.g., hybrid PCB stack-ups).
