PROBLEM TO BE SOLVED: To provide a vehicular notification system that can suppress occurrence of acoustic echo even if a condition set by an occupant is varied.SOLUTION: The vehicular notification system is an emergency notification device 10 for communication with a vehicle exterior notification device, which comprises: a sound processing portion 30 that receives transmission signals picked up by a microphone 16 and generates audio output by outputting reception signals received from the vehicle exterior notification device to a speaker 17; and a control portion 11 that controls the sound processing portion 30. The sound processing portion 30 has an echo canceller circuit 31 and an echo suppressor circuit 35 which have acoustic echo removal characteristics which can be set according to predetermined control parameters (G, D and K), which remove at lest acoustic echo components included in the transmission signals. The control portion 11 sets the acoustic echo removal characteristics by correcting the control parameters, according to states of a vehicle including at least a position of an occupant 6 on a driver seat 60 with respect to the microphone 16 and the speaker 17.SELECTED DRAWING: Figure 4

    【課題】乗員に起因する条件が変化しても音響エコーの発生を抑制することが可能な車両用通報システムを提供する。【解決手段】車外通話装置と通話するための緊急通報装置10であって、マイク16により収音された送話信号を受け取ると共に、車外通話装置から受け取った受話信号をスピーカ17へ出力して音声出力を発生させる音処理部30と、音処理部30を制御する制御部11とを備え、音処理部30は、所定の制御パラメータ(G,D,K)によって設定可能な音響エコー除去特性を有するエコーキャンセラ回路31,エコーサプレッサ回路35を有し、これらにより少なくとも送話信号に含まれる音響エコー成分を除去するように構成されており、制御部11は、少なくともマイク16及びスピーカ17に対する運転席60の乗員6の位置を含む車両状態に応じて制御パラメータを補正することにより、音響エコー除去特性を設定する。【選択図】図4
