Title:
車両用警告システム
Document Type and Number:
Japanese Patent JP7172876
Kind Code:
B2
Abstract:
To provide a vehicle warning system capable of reliably notifying a passenger of warning.SOLUTION: A vehicle warning system includes an ultrasonic generation element array 10, a head position measurement device 11, and a control device 12. The head position measurement device 11 measures a position and shape of a head H of a driver, and transmits the measured data to the control device 12. When a signal to issue warning to the driver is received, the control device 12 controls driving timing of each ultrasonic generation element 13 so as to allow an ultrasonic wave to be emitted by the ultrasonic generation element array 10 to be converged at a position of an area where pressure of the head H of the driver is applied. The ultrasonic generation element array 10 emits an ultrasonic wave by control by the control device 12. An ultrasonic wave is converged on an area where pressure of the head H of the driver is applied, and the driver receives acoustic radiation pressure. Thus, the driver can be warned by pressure.SELECTED DRAWING: Figure 1
