  • Patent number: 12246690
    Abstract: An apparatus for estimating brake judder of a vehicle and a method thereof includes a communication device that receives sensor data from a plurality of vehicles, and a controller that extracts learning data by pre-processing the sensor data, trains a clustering model to group characteristic data corresponding to the learning data into a preset number of clusters, and estimates brake judder of a target vehicle based on the learned clustering model.

  • Publication number: 20240416876
    Abstract: An embodiment emergency braking apparatus for a vehicle includes a memory storing a required control amount determination algorithm for non-occurrence of a judder and a required control amount determination algorithm for occurrence of the judder and an emergency braking controller that determines whether the judder occurs based on judder prediction information, determines whether a current situation is a dangerous situation based on vehicle forward detection information and a dangerous situation determination criterion for the occurrence of the judder, operates based on the required control amount determination algorithm for the occurrence of the judder, determines a primary required control amount based on the required control amount determination algorithm for the non-occurrence of the judder, selects a compensation coefficient corresponding to a judder magnitude, determines a compensation value based on the compensation coefficient, and determines a final required control amount by applying the compensatio
