This document describes motion planning with variable grid resolution for graph-search-based planning. An example system includes a processor that obtains an initial pose, a goal pose, and an obstacle map for an environment. The processor uses a motion-planning algorithm to determine a path or trajectory using two or more grid resolutions for a graph-based search.

This document describes trajectory planning in a three-dimensional (3D) search space with a space-time artificial potential field. An example system includes a processor that obtains an initial pose, a goal pose, and an obstacle map for an environment. The processor uses a parking trajectory algorithm to determine a trajectory by searching in a space-time artificial potential field.

This allows motion planning for autonomous parking, especially with static and dynamic objects present, to determine an optimal trajectory in a single iteration.
Described herein is NLS using a bounded linear initial search space and a fixed grid with pre-calculated variables. Specifically, first and second signals with unknown first and second elevation angles, respectively, are received that have been reflected by an object, with the second signal also having been reflected off the ground. A line of second angles is then established as a function of first angles, a sensor height, and a range to the object. The first angles being bound by a function of the sensor height and the range and a function of the sensor height, the range, and the maximum height. A search algorithm is then used to search for an initial elevation angle pair along the line. The initial elevation angle pair may then be fed into a refinement algorithm (e.g., non-linear least squares) to determine the elevation angles associated with the first and second signals.

External Sensing for Monitoring Health of Vehicle Electric Energy Storage
This document describes external sensing for passively monitoring health of vehicle electric energy storage. Techniques for relying on measurements reported from sensors arranged external to an energy storage device (ESD) are described. Overall health of the ESD is inferred without relying on charging circuits or self-diagnosing on the ESD. External measurements (e.g., capacitive, inductance, temperature) are used to identify potential physical deformations or other signs of physical failure of an ESD. These measurements provide early warnings of impending ESD failure. Other ESD monitors may fail to detect these conditions and/or be too slow to prevent damage from thermal runaways or other catastrophic failures when they occur. A described unintrusive ESD health monitoring is described to enhance ESD safety; dangerous surface temperatures, physical swelling, or other unsafe conditions are detected early to intervene and cease operations before it is too late.

This document describes techniques and systems for fusion of object classes. Sensor data, related to an object, can be obtained from different types of sensor systems. Using techniques based on a Dempster Shafer framework, masses of each potential object class based on data from a respective sensor can be calculated. The respective masses of each potential object class, based on the different sensor systems, can be combined to generate a fused mass for each potential object class. Probabilities for each potential object class can be calculated based on the respective fused masses. An assigned object class for the object can be selected based on a probability exceeding some decision threshold. This assigned object class may then be available for an object tracker, an object fusion system, or other vehicle system resulting in a safer driving experience.

This document describes techniques and systems for electromagnetic response simulation for arbitrary road surface profiles. An electromagnetic response simulator receives a position and an orientation of both an electromagnetic sensor (e.g., radar sensor) and a target, and a geometric profile of a road surface. The road surface may vary in elevation in the lateral and/or longitudinal directions. The electromagnetic response simulator estimates reflection points of electromagnetic rays along the geometric profile of the road surface and translates the positions and the orientations of the electromagnetic sensor and the target into respective local coordinates corresponding to each reflection point. The electromagnetic responses can then be calculated, corresponding simulated rays can be output to a sensor simulator. In this manner, the variance in elevation of a road surface can be included in generating simulated rays, and the electromagnetic response simulator may more accurately simulate real-world electromagnetic responses.

Target Testing Based on Raw Uncalibrated Radar Data
This document describes techniques and systems for target testing based on raw uncalibrated radar data. Channel responses (e.g., Raw radar data) are obtained from a sensor having a Multiple-input multiple-output (MIMO) antenna array. The channel responses, based on target detections, are arranged in a MIMO measurement matrix. The dominant singular values of the observation matrix are determined, and the quantity of dominant singular values is compared to the number of targets, either from prior information or estimated after calibration, in the FOV of the sensor. If the number of dominant singular values is different than the number of targets, either from prior information or estimated after calibration, then further analysis may be used to determine the cause of the difference. In this manner, potential damaged sensors or degradation from cover reflections may be identified, sensor status independent of calibration may be monitored, and calibration may be improved.
This document describes techniques and systems for autonomous parking in locations without cellular coverage. A system can include a processor that obtains a request to autonomously park in a parking environment. The system can then determine whether parking space information indicating an available space was obtained. In response to determining that parking space information was obtained, the system can autonomously operate the host vehicle to navigate to and park in the available space. The system determines whether a communication system of the host vehicle has a cellular connection available to aid in the navigation. In response to a determination that the cellular connection is not available, the system communicates the location of the host vehicle to the processor via a proxy vehicle with an operable cellular connection. By utilizing a mesh network among vehicles to share their cellular connections, autonomous parking features may remain available in locations without cellular coverage.

Capacitive Sensing for Detecting Battery Deformations
This document describes techniques for capacitive sensing to detect battery deformations during wireless charging of rechargeable batteries. An example system includes a processor that detects the placement of a mobile device with a rechargeable battery on a wireless charger. Before or during the charging session, the processor obtains capacitance values from multiple capacitive sensors integrated into or on the wireless charger. The processor analyzes the capacitance values and determines whether they indicate the deformation of the rechargeable battery, which may be caused by swelling or enlargement. In response to determining that the capacitance values indicate the deformation of the rechargeable battery, the processor does not initiate or terminates the charging session. In this way, the described techniques and systems can monitor for battery swelling and protect consumers and their mobile devices from the effects of battery swelling.

This document describes techniques for implementing active steering assistance for vehicle turns and parking maneuvers. A host vehicle may move on a vehicle path and detect a road barrier (e.g., a curb) with a shorter height relative a driving surface than the height of a vehicle wheel. When a collision is predicted between the road barrier and the host vehicle, a steering correction is determined for changing a vehicle direction on the vehicle path to prevent the collision. When the steering correction is within a safety threshold (e.g., safe for driving at slow speed), a steering assistance function is activated. The steering assistance function causes an adjustment to steering controls, which change the vehicle direction based on the steering correction determined to avoid the road barrier in the driving surface in time to prevent the predicted collision.
