  • Publication number: 20240101149
    Abstract: A method of automatically detecting a dynamic object recognition error in an autonomous vehicle is provided. The method includes parsing sensor data obtained by frame units from a sensor device equipped in an autonomous vehicle to generate raw data by using a parser, analyzing the raw data to output a dynamic object detection result by using a dynamic object recognition model, determining that detection of a dynamic object recognition error succeeds by using an error detector when the dynamic object detection result satisfies an error detection condition, and storing the raw data and the dynamic object detection result by using a non-volatile memory when the detection of the dynamic object recognition error succeeds.

  • Publication number: 20210284145
    Abstract: A driver assist device and a method for operating the device are provided. The driver assist device includes a processor and a non-transitory storage medium containing program instructions executed by the processor. When a vehicle changes a lane from a traveling lane to a target lane, the processor determines a possibility of collision between the vehicle and another vehicle in the target lane and calculates an expected amount of deceleration of the vehicle with respect to a target vehicle in the target lane when there is no possibility of collision between the vehicle and the another vehicle. The processor compares the calculated expected amount of deceleration of the vehicle with a deceleration criterion, and determines whether to perform lane change assist control based on the comparison result.
