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.

Abstract: Presented are systems and methods for extracting lane-level information of designated road segments by mining vehicle dynamics data traces. A method for controlling operation of a motor vehicle includes: determining the vehicle's location; identifying a road segment corresponding to the vehicle's location; receiving road-level data associated with this road segment; determining a turning angle and centerline for the road segment; receiving vehicle data indicative of vehicle locations and dynamics for multiple vehicles travelling on the road segment; determining, from this vehicle data, trajectory data indicative of start points, end points, and centerline offset distances for these vehicles; identifying total driving lanes for the road segment by processing the trajectory data with a clustering algorithm given the turning angle and centerline; extracting virtual trajectories for the driving lanes; and commanding a vehicle subsystem to execute a control operation based on an extracted virtual trajectory for at least one driving lane.

Abstract: Methods and apparatus are provided for damage risk indication of a steering system of a vehicle. The apparatus includes a sensor system and a processing device. The sensor system is configured to detect a velocity of a servo unit of a steering system of the vehicle. The processing device is configured to determine an acceleration value of the servo unit and to compare the acceleration value, velocity values and thresholds of the servo unit with an acceleration value threshold, and to generate a warning signal if the acceleration value of the servo unit exceeds the acceleration value threshold. Thus, a damage risk is determined and the vehicle can be subjected to further damage investigation.
