PROBLEM TO BE SOLVED: To provide a horn controller capable of switching between on/off of a security function at an optional timing without change of a body ECU.SOLUTION: A horn controller 11 is provided on a vehicle which comprises a horn device 13 comprising: a high sound area horn 29 and a low sound area horn 35 for outputting a horn sound; a horn relay 17 for supplying drive power to the horns; and a horn harness 15 for connecting electrically, the horn relay and the high sound area horn 29 and the low sound area horn 35. The horn controller comprises: an electric wire 41 for disconnection detection which is provided along the horn harness; a disconnection detection circuit 43 for outputting a disconnection detection signal when detecting disconnection of the disconnection detection electric wire 41; and a microcomputer 45 for turning the horn relay on based on the disconnection detection signal when an ignition signal or an accessory signal is in an off state, so as to make the horn relay supply the drive power to the horn harness.SELECTED DRAWING: Figure 1
【課題】ボデーECU等の変更なしで、任意のタイミングでセキュリティ機能をON/OFFさせることができるホーン制御装置を提供する。【解決手段】警笛音を出力する高音域ホーン29及び低音域ホーン35と、これらホーンへ駆動電力を供給するホーンリレー17と、ホーンリレーと高音域ホーン29及び低音域ホーン35とを電気的に接続するホーンハーネス15とを備えるホーン装置13を有する車両に設けられるホーン制御装置11であって、ホーンハーネスに沿って配索される断線検知用電線41と、断線検知用電線41の断線を検知した場合に断線検知信号を発する断線検知回路43と、イグニッション信号又はアクセサリ信号がOFFの場合には、断線検知信号に基づいてホーンリレーをONさせホーンハーネスに駆動電力を供給させるマイクロコンピュータ45と、を備える。【選択図】図1
