System for introducing sound outside vehicle

摘要

Introduction of sounds outside a vehicle is automatically controlled according to a driving state of the vehicle. In a vehicle, a microphone device that collects sounds outside the vehicle and a speaker device that reproduces the collected sounds are installed. When a gear position for the vehicle is a reverse driving position, and until the vehicle reaches a predetermined speed for the first time after a key position in an ignition key switch is switched from an off position to an accessories position or an on position, the collected sounds are reproduced. The collected sounds are transmitted to a car navigation device or a car audio system via wires or wirelessly. When the sounds outside the vehicle are reproduced, sound reproduction in the car navigation device or the car audio system is stopped and the sounds outside the vehicle are reproduced at a set volume.

1. A system for introducing a sound outside a vehicle, the system comprising:
a microphone device installed outside an interior of the vehicle, the microphone device collecting the sound outside the vehicle; a speaker device installed inside the interior of the vehicle; a sound reproduction system that reproduces the sound collected by the microphone device, via the speaker device; and a sound reproduction control device that receives an input of a signal indicating a gear position currently selected for the vehicle, and controls the sound reproduction system so that if the gear position is a reverse driving position, the sound collected by the microphone device is reproduced via the speaker device, and if the gear position is a forward driving position, the reproduction of the sound collected by the microphone device is stopped or a volume of the sound reproduced is reduced to be smaller than that for reverse driving.
