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

Claim 0:
1. A vehicle control system for use in a vehicle, the vehicle control system comprising:
a communication circuit to be located within a vehicle body of the vehicle;
an internal sensor to be located in a forward facing direction of the vehicle; and
a controller connected to the communication circuit and the internal sensor, wherein the controller is configured to:
detect an impact to the vehicle through the internal sensor;
calculate an impulse for the detected impact;
determine an initially estimated bump shape based on the calculated impulse;
classify the initially estimated bump shape into a specific form;
load a dynamic model of the vehicle;
calculate prediction data based on the dynamic model of the vehicle;
analyze an error of the prediction data based on the calculated impulse and the initially estimated bump shape classified as the specific form;
repeat analyzing of 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;
determine an estimated bump shape based on the prediction data when the error satisfies the error reference;
match first bump information that represents the estimated bump shape and second bump information acquired from a database by using the communication circuit;
update bump information of the database based on a matching result; and
cause 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.
