Abstract

See full text

Provided are a system for correcting a signal of an ultrasonic sensor according to a current weather condition, and a method of operating the same. The system for correcting a signal of an ultrasonic sensor according to a weather condition includes: a user terminal configured to externally acquire information about an ambient condition at a current position of a vehicle (for example, current temperature, and current humidity, and current atmospheric pressure) from an external server; and a vehicle terminal configured to calculate a current sound absorption coefficient based on the current ambient condition, determine whether a signal correction of the ultrasonic sensor mounted in the vehicle is needed by comparing the calculated current sound absorption coefficient with a preset standard sound absorption coefficient, and correct a received ultrasonic signal transmitted by the ultrasonic sensor and reflected from an obstacle based on a result determined by the vehicle terminal.
