Patent ID: 11874136
Assignee: HYUNDAI MOTOR COMPANY
Field: Measurement (Instruments)
Classification: CPC G  B | IPC B  G

Claim 16:
17. A computer readable non-transitory recording medium configured to store programs for executing operations of:
detecting an impact to a vehicle;
calculating an impulse for the detected impact;
estimating a bump shape based on the calculated impulse;
matching first bump information that represents the estimated bump shape and second bump information acquired from a database;
updating bump information of the database based on a matching result; and
causing a driving speed of the vehicle to be reduced in response to detecting the impact to the vehicle and based on the estimated bump shape
wherein estimating the bump shape based on the calculated impulse comprises:
classifying the bump shape into a specific form;
loading a dynamic model of the vehicle;
calculating prediction data based on the dynamic model of the vehicle;
analyzing an error of the prediction data based on the calculated impulse and the bump shape classified as the specific form;
analyzing the error of the prediction data after the prediction data is changed based on the error when the error does not satisfy an error reference; and
determining the bump shape based on the prediction data when the error satisfies the error reference.
