Claims

[Scope of utility model registration request]

crosswind detection means for detecting crosswind applied to the vehicle;
a transmitting means for transmitting ultrasonic waves in a forward direction of the vehicle; a receiving means for receiving reflected waves from the ultrasonic waves transmitted from the transmitting means reflected on a road surface; The present invention is characterized by comprising a determining means for determining irregularities in the front direction of the vehicle based on the vehicle traveling direction, and a means for prohibiting determination by the determining means when the crosswind detected by the crosswind detecting means is equal to or higher than a certain value. Road condition prediction sensor.
