Abstract: A global positioning system (GPS)-bias detection and reduction system including a GPS-bias model having GPS statistical data creating a database representing data collected from a vehicle group having thousands or multiple thousands of vehicles saved in a database. At least one newly collected vehicle GPS data point is compared to the GPS statistical data to reduce negative effects of GPS-bias and to update the vehicle GPS-bias correction based on a previous GPS-bias model. A selected road node and a segment of a roadway have a map matching performed using a nearest service from a collection location of the GPS statistical data. A GPS-bias is calculated using a look-up of the database. An estimated horizontal position error (EHPE) defining a quality indicator is applied to distinguish a good quality GPS statistical data from a poor quality GPS statistical data.

Abstract: A charging unit guidance system includes a processor and a memory. The memory includes instructions that upon execution by the processor, cause the processor to receive a sequence of user states associated with a user of a first autonomous vehicle, each user state being one of a walking state and an at-charging-unit state and the sequence of user states being based on a sequence of observed user speeds associated with detected user position data associated with movement of the user from the first autonomous vehicle to a charging unit and at the charging unit, determine a charging unit location of the charging unit based on a correlation between the at-charging-unit states in the sequence of user states and the user position data, and upload the charging unit location associated with the charging unit to an edge computing system, the edge computing system being configured to provide guidance instructions to the charging unit to a second autonomous vehicle based at least in part on the charging unit location.

Abstract: A sequence of images and a vehicle location associated with each of the images is received at a traffic light ROI management system. At least one traffic light is detected in each image. A ECS traffic light ROI is defined for each image. The ECS traffic light ROI encloses the detected traffic lights. A visual feature template is generated for each image. The visual feature template is based on the ECS traffic light ROI for the image. Each visual feature template is mapped to the vehicle location associated with the image to a HD map. The HD map is transmitted to an autonomous vehicle to enable the autonomous vehicle to identify a real-time traffic light ROI in a real-time image based on a match between a first visual feature template and real-time visual features of the real-time image at the vehicle location associated with the first visual feature template.

Abstract: A system to map an outdoor environment includes at least one map including an access point (AP) position map, and a reflector map generated from multiple wireless signals collected by multiple automobile vehicles. A set of crowd-sourced data is collected from individual ones of the multiple automobile vehicles derived from multiple perception sensors when the at least one of the multiple automobile vehicles pass a mapping area. A data package is created from the set of crowd-sourced data including a group of wireless positioning samples and a group of visual features, the data package being forwarded to an On-Cloud database where On-Cloud Mapping is conducted. Multiple range measurements yield circular AP candidate positions within a free-space operating window of vehicle operation of the multiple automobile vehicles. Application of the range measurement plus multiple reflectors defined at multiple planar reflective surfaces improves the AP candidate positions.

Abstract: A system and method for passively and actively monitoring and determining the location of at least one mechanical anomaly for a power steering system of a vehicle is disclosed. The system includes one or more processors and a memory coupled to the processors. The memory stores a baseline waveform and data comprising program code that, when executed by the one or more processors, causes the system to receive at least one excitation signal and at least one response signal. The power steering system creates the response signal in response to receiving the excitation signal. In response to receiving the excitation signal and the response signal, the system is caused to estimate the frequency response between the excitation signal and the response signal based on a fast Fourier transform (FFT) algorithm. The frequency response is represented by an estimated waveform.
