Abstract

The invention discloses a sound output control system. Provided is a technique capable of suppressing missing provision of information during a silence period and suppressing delay in provision of the information. The control device performs output state control for controlling the output state of the sound signal output from the sound source device and the output state of the buzzing sound output from the buzzing device according to the driving environment information. In the output state control, according to the driving environment information, whether the output condition of the chirp sound is satisfied is determined. When it is determined that the output condition is satisfied, a muting signal that mutes the output of the sound signal is output to the sound source device, and a sounding signal including the muting information is output to the sounding device. The muting information comprises information of starting timing of output of the chirp sound. The start timing is variably set according to a degree of importance of information provided to an occupant of the vehicle.

Description

technical field [0001] The present invention relates to a sound output control system mounted on a vehicle. Background technique [0002] Japanese Unexamined Patent Publication No. 9-73588 discloses a vehicle sound processing device having a mute function. This conventional device mutes the output of other sound signals when outputting the alarm sound. The main purpose of outputting the alarm sound is to provide information to the driver of the vehicle. In this regard, according to the mute function, the warning sound can be output while the output of other sound signals is muted, and the driver can be made aware of the warning sound. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Application Laid-Open No. 9-73588 Contents of the invention [0006] However, there is a certain interval between the start of silence and the output of the alarm sound. If the reliable provision of information is important, the interval ...
