PROBLEM TO BE SOLVED: To perform notification which can be identified/recognized by only a driver.SOLUTION: A vehicular notification device 1 includes: vibration means 4 provided in a seat in a cabin; signal generation means 3 for generating a first sweep signal which has a frequency changed in a prescribed frequency range; vibration pickup means 5 for picking up vibration in the cabin; a frequency analysis means 6 which determines a frequency characteristic of the vibration in the cabin in a state that the first sweep signal is input in the vibration means 4 during a vehicle stopping time and a vehicle traveling time and detects the frequency range in which a signal level during the vehicle traveling time is higher than a signal level during the vehicle stopping time by prescribed level amount or more; and frequency variable means 7 which generates a filter for limiting the signal level in the detected frequency range, applies the filter to the first sweep signal, and generates a second sweep signal.SELECTED DRAWING: Figure 1
【課題】運転者のみに識別・認識させることが可能な報知を行う。【解決手段】車両用報知装置1は、車室内のシートに設けられた振動手段4と、所定の周波数範囲で周波数を変化させた第1スイープ信号を生成する信号生成手段3と、車室内の振動を収振する収振手段5と、車両停止時および車両走行時に、第1スイープ信号を振動手段4へ入力させた状態で、車室内の振動の周波数特性とを求めて、車両停止時の信号レベルよりも、車両走行時の信号レベルの方が所定レベル量以上高い周波数範囲を検出する周波数解析手段6と、検出された周波数範囲の信号レベルを制限させるフィルタを生成して第1スイープ信号に適用し、第2スイープ信号を生成する周波数可変手段7とを有する。【選択図】図1
