7 results about "Tailgating" patented technology

Tailgating is when a driver drives behind another vehicle while not leaving sufficient distance to stop without causing a collision if the vehicle in front stops suddenly. The safe distance for following another vehicle varies depending on various factors including vehicle speed, weather, visibility and other road conditions. Some jurisdictions may require a minimal gap of a specified distance or time interval. When following heavy vehicles or in less than ideal conditions (e.g. low light or rain), a longer distance is recommended.

Systems and methods for training a model for determining vehicle following distance

Systems, methods, models, and training data for models are discussed, for determining vehicle positioning, and in particular identifying tailgating. Simulated training images showing vehicles following other vehicles, under various conditions, are generated using a virtual environment. Models are trained to determine following distance between two vehicles. Trained models are used to in detection of tailgating, based on determined distance between two vehicles. Results of tailgating are output to warn a driver, or to provide a report on driver behavior.

Video monitoring method and system for barrier gate car following prevention

The invention relates to the technical field of video monitoring processing, and particularly discloses a video monitoring method and system for barrier gate car following prevention, and the method comprises the following steps: extracting a foreground target in a video frame; extracting a target residual area based on the mirror surface highlight area of the foreground target; generating a complete contour model of the foreground target based on the target residual region; determining a position point of the complete contour model in each video frame, and connecting the position points to form a motion track of the foreground target; and sorting the foreground targets according to the sequence of the foreground targets appearing in the monitoring area, obtaining motion tracks A1 and A2 of two adjacent foreground targets in the sorting, and judging whether a car following behavior exists or not based on the motion tracks A1 and A2. According to the invention, the accuracy of car following judgment is improved.

Verification of the origin of abnormal driving

PendingUS20260070561A1External condition input parametersDistracted drivingReckless driving
Systems and methods are provided for programmatically verifying an origin of abnormal driving. Some examples of abnormal driving may include aggressive driving (e.g., tailgating, cut-in lane, etc.), distracted driving (e.g., swerving, delayed reaction, etc.), and reckless driving (e.g., green light running, lane change without signaling, etc.). For example, the systems and methods may receive an identification of a second vehicle performing abnormal driving from an ego vehicle; initiate a verification process of the identification of the abnormal driving; access driving data associated with an origin of the abnormal driving, wherein the driving data includes the ego vehicle and the second vehicle; using the driving data, determine a confirm or deny decision regarding the identification of the second vehicle from the ego vehicle; and provide the confirm or deny decision.
