Abstract

A method for sensing a wind and controlling a vehicle using a parking assist system (PAS) including a plurality of ultrasonic sensors and output devices is provided. The method includes controlling, by a controller, a first ultrasonic sensor disposed at a front side of a vehicle to transmit an ultrasonic signal. Respective primary indirect signals received from the ultrasonic sensors at the front side other than the first ultrasonic sensor are received by the controller. A second ultrasonic sensor adjacent to the first ultrasonic sensor to transmit the ultrasonic signal is controlled by the controller. Respective primary indirect signals received from the ultrasonic sensors at the front side other than the second ultrasonic sensor are received by the controller. The direction of the wind is sensed by the controller through a comparison of relative sizes of waveforms of each primary indirect signal and each secondary indirect signal.

Claims

1. A method for sensing a wind and controlling a vehicle using a parking assist system (PAS) including a plurality of ultrasonic sensors and output devices, comprising:

controlling, by a controller, a first ultrasonic sensor disposed at a front side of the vehicle to transmit an ultrasonic signal;

receiving, by the controller, respective primary indirect signals received from the ultrasonic sensors at the front side other than the first ultrasonic sensor;

controlling, by the controller, a second ultrasonic sensor adjacent to the first ultrasonic sensor to transmit the ultrasonic signal;

receiving, by the controller, respective primary indirect signals received from the ultrasonic sensors at the front side other than the second ultrasonic sensor; and

sensing, by the controller, the direction of the wind through a comparison of relative sizes of waveforms of each primary indirect signal and each secondary indirect signal.

2. The method of claim 1, further comprising:

sensing, by the controller, that a strong wind moves toward the second ultrasonic sensor from the first ultrasonic sensor when the waveform of each primary indirect signal is larger than the waveform of each secondary indirect signal; and

sensing, by the controller, that the strong wind moves toward the first ultrasonic sensor from the second ultrasonic sensor when the waveform of each primary indirect signal is smaller than the waveform of each secondary indirect signal.

3. The method of claim 1, further comprising:

comparing, by the controller, a waveform of each primary indirect signal or a secondary interference signal newly received with the waveform of each primary indirect signal or each secondary indirect signal.

4. The method of claim 3, further comprising:

transmitting, by the controller, a warning message to an output when the sensed intensity of the wind is a first intensity.

5. The method of claim 3, further comprising:

providing, by the controller, steering assistance force from a steering controller when the sensed intensity of the wind is a second intensity and the steering assistance force to correspond to the sensed direction of the wind.

6. The method of claim 1, further comprising:

controlling, by the controller, a third ultrasonic sensor disposed at a rear side of the vehicle to transmit the ultrasonic signal;

receiving, by the controller, respective primary indirect signals received from rear ultrasonic sensors other than the third ultrasonic sensor;

controlling, by the controller, a fourth ultrasonic sensor adjacent to the third ultrasonic sensor to transmit the ultrasonic signal; and

further receiving, by the controller, respective secondary indirect signals received from the rear ultrasonic sensors other than the fourth ultrasonic sensor.

7. The method of claim 3, further comprising:

comparing, by the controller, a waveform of a primary indirect signal or a secondary indirect signal newly received with the waveform of each primary indirect signal or each secondary indirect signal; and

changing the intensity of the wind in proportion to the waveform of the primary indirect signal or the secondary indirect signal newly received with the waveform of each primary indirect signal or each secondary indirect signal.
