Method for detecting side wind acting on e.g. car, involves comparing noise signals of left and right sided ultrasonic sensors, and detecting side wind based on variations of noise signals of left and right sided sensors

摘要

The method involves detecting noise signals by a set of ultrasonic sensors (3a, 3b) arranged at a left side of a motor vehicle (1) and another set of ultrasonic sensors (3c, 3d) arranged at a right side of the vehicle. The noise signals of the left and right sided ultrasonic sensors are compared. Side wind (2) is detected based on variations of the noise signal of the left sided ultrasonic sensor from the noise signal of the right sided ultrasonic sensor. Strength of the side wind is detected based on amount of the variations. A warning signal is output based on the strength. An independent claim is also included for a device for detecting side wind acting on a vehicle.
