Patent number: 12038503Abstract: A fast ramp frequency modulated continuous wave (FMCW) radar system is described herein, where the fast ramp FMCW radar system is configured to employ velocity labeled multiplexing (VLM) in connection with generating detections for objects in a scene. Transmitters in the radar system are assigned different velocity labels that corresponds to different phase rates of change of consecutive chirps in signals emitted by the transmitters. Approaches for generating detections based upon echo signals that correspond to the emitted signals are also described herein.Type: GrantFiled: August 4, 2021Date of Patent: July 16, 2024Assignee: GM CRUISE HOLDINGS LLCInventors: Andre Giere, Özlem Karaca, Johanna Gütlein-Holzer, Richard Johann Körber

Patent number: 12039868Abstract: A cross-traffic warning system for a motor vehicle includes first and second input devices transmitting associated first and second input signals for first and second detected objects positioned on the roadway. The system further includes a computer having one or more processors and a computer readable medium storing instructions. The processor is programmed to determine that the first object is a Vulnerable Road User (“VRU”) travelling on a first path based on the first input signal. The processor is further programmed to determine that the second object is a third party vehicle and further that the VRU and the third party vehicle are travelling on an associated one of first and second paths to imminently collide with one another based on the first and second input signals.

Publication number: 20240230866Abstract: Misalignment of camera and light detection and ranging (LIDAR) sensors can impact operations performed by an autonomous vehicle (AV) stack. Misalignment, or deviation from initial alignment over time, can occur in pitch, yaw, and roll dimensions. To address alignment issues, AV sensors may be calibrated before the AV drives on roadways. Additionally, AV sensors may be routinely calibrated at a maintenance facility to detect deviations from initial alignment of the sensors. Offline calibration of AV sensors in maintenance facilities can be inefficient and can significantly increase overhead. Therefore, online calibration of AV sensor misalignment may alleviate some of these concerns. Additionally, online calibration of AV sensors enables efficient monitoring and effective calibration of AV sensor alignment for a whole fleet of AVs while the fleet is on the road.Type: ApplicationFiled: January 5, 2023Publication date: July 11, 2024Applicant: GM Cruise Holdings LLCInventors: Zhonghua Ma, Xiaoyu Zhou, Himil Narayan Sheth
