Abstract: A method is provided for assigning a bounding box to an object in an environment of a vehicle. Data related to objects located in the environment of the vehicle are acquired via a sensor. Based on the data, a respective spatial location and a respective size of a plurality of preliminary bounding boxes are determined such that each preliminary bounding box covers one of the objects at least partly. A respective velocity of each preliminary bounding box is estimated based on the data. A subset of the plurality of preliminary bounding boxes being related to a respective one of the objects is selected, where the subset is selected based on the respective velocity of each of the preliminary bounding boxes. A final bounding box is assigned to the respective one of the objects by merging the preliminary bounding boxes of the corresponding subset.

Abstract: A method is provided for estimating an angle of an object with respect to a vehicle. A transformation of reflected radar signals is calculated, wherein the result of the transformation depends on a range with respect to the vehicle. A long beam vector is generated for respective range bins provided by the transformation by rearranging the result of the transformation such that the respective long beam vector comprises elements of the transformation from radar all receiver elements for each range bin. A reference vector is calculated for each range bin based on a signal model which depends on the motion of the target object relative to the vehicle and which is parameterized regarding the angle of the target object. The long beam vector and the reference vector are correlated, and the angle of the target object is determined based on the correlation result.

Abstract: This document describes techniques and systems for vehicle localization based on pose corrections from remote vehicles in parking garages and other GNSS denial environments. A system can include a processor and computer-readable storage media comprising instructions that, when executed by the processor, cause the system to autonomously operate a host vehicle and determine an estimated pose of the host vehicle within the GNSS denial environment. The instructions also cause the processor to transmit a pose request to a remote vehicle in the GNSS denial environment. In response to the pose request, the system can receive a corrected pose of the host vehicle from the remote vehicle. The instructions further cause the processor to use the corrected pose to determine an updated pose for the host vehicle. In this way, the system can provide highly accurate vehicle localization in GNSS denial environments in a cost-effective manner.

Abstract: A method is provided for determining a pitch angle of a perception system of a vehicle with respect to a road surface on which the vehicle is located. Via the perception system, road perception information is detected from the road surface, and object perception information is detected from objects being different from the road surface. A primary pitch angle is determined by using the road perception information, and a relative pitch angle is determined by using the object perception information. The primary pitch angle and the relative pitch angle are combined in order to determine a final pitch angle of the perception system.

Abstract: A method is provided for determining radar transmission and reflection characteristics of a vehicle component in proximity to a radar system. A parameter sweep array including input data sets is defined, each input data set including array elements which cover a range of a respective predefined parameter associated with the vehicle component. A reflection coefficient is calculated for radar waves transmitted by the radar system for each array element of the input data sets and for predefined angles with respect to a surface of the vehicle component. For each input data set and for each predefined angle, a respective worst-case element is determined having a maximum value of the reflection coefficient. A worst-case data set including the worst-case elements is generated for each input data set and for the predefined angles in order to provide a validation of the transmission and reflection characteristics of the vehicle component.

Abstract: Perception systems and methods include use of occlusion constraints for resolving tracks from multiple types of sensors. An occlusion constraint is applied to an association between a radar track and vision track to indicate a probability of occlusion. The perception systems and methods refrain from evaluating occluded and collected radar tracks and vision tracks. The probability of occlusion is utilized for deemphasizing pairs of radar tracks and vision tracks with a high likelihood of occlusion and therefore, not useful for tracking. Improved perception data is provided and more closely represents multiple complex data sets for a vehicle to prevent a collision with an occluded object as the vehicle operates in an environment.

Abstract: The techniques and systems herein enable ESA modification based on manual steering inputs. Specifically, a score is determined for a manual steering input to a host vehicle while an ESA is actively applying an ESA steering input to the host vehicle. The score quantifies an amount of additional steering input relative to the ESA steering input (e.g. additional steering angle, steering wheel torque). The ESA steering input is maintained, modified, or canceled based on the score. By doing so, the system is able to effectively adapt the ESA to the manual steering inputs thereby allowing for effective collision mitigation while ensuring that the vehicles operate as intended by the drivers.

Abstract: This document describes techniques and systems for accurate and efficient electromagnetic response for a sensor simulator. Target information and sensor parameters for an electromagnetic sensor are simulated in an environment that includes a ground plane. Electromagnetic rays that may be detected by the sensor or an image of the sensor are launched from the simulated sensor toward the target and an image of the target about the ground plane to determine a complex electromagnetic response of the target. A ray-tracing algorithm is applied to trace the forward wave propagation of electromagnetic rays in the environment that considers rays bouncing between the target and the image of the target. An electromagnetic response can be modeled based on the congregation of the electromagnetic response of all backward paths of all bounces of all rays. In this manner, an efficient and accurate electromagnetic response model may be approximated.
