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

Claim 9:
10. A method for controlling a vehicle, the method comprising:
detecting an impact to the 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 using a communication circuit;
updating bump information of the database based on a matching result; and
reducing a driving speed of the vehicle in response to detecting the impact to the vehicle and based on the estimated bump shape;
wherein estimating the bump shape 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.
