In-vehicle response indicating system for vehicle whistling

Abstract

The invention relates to an in-vehicle response indicating system for vehicle whistling. The in-vehicle response indicating system mainly consists of four vehicle whistling sound detecting sensors, a host vehicle whistling sound shielding circuit, a host vehicle whistling detecting circuit, a vehicle position judging circuit, an audio frequency processing circuit, a user-defined whistling sound selector, an audio frequency magnifying circuit, and a four-track earphone or four-loudspeaker system, wherein the four vehicle whistling sound detecting sensors are distributed at four corners of a vehicle, are connected with the host vehicle whistling sound shielding circuit so as to prevent the condition that host vehicle whistling sound is detected; when whistling of other vehicles is detected, the vehicle position judging circuit judges the position where the other vehicles whistle; the audio frequency processing circuit is connected with the user-defined whistling sound selector, so that the type of the broadcasted audio frequency can be selected and synthetized; and the audio frequency magnifying circuit magnifies a prompting sound which needs to be broadcasted, the prompting audio frequency is broadcasted in the vehicle through the four-track earphone or four-loudspeaker system, so that prompting and position restoring in an auditory system of a driver for the whistling of the other vehicles are realized.

Description

technical field [0001] The invention relates to an automobile safety indicating device, which can ensure that the driver of a car can hear the sound of the whistle of the coming car in the car when the car coming from the rear whistles to overtake or the car coming from the front whistles to remind attention, so as to reduce the occurrence of accidents. Background technique [0002] With the improvement of people's living standards, cars are constantly entering the family, and the number of cars is increasing. The roads in some cities are becoming more and more congested, and there are more and more cars on the highway. Due to the continuous improvement of the manufacturing level of modern cars, people The requirements for the mute effect in the car are getting higher and higher, and it is often one-sided to pursue that the driving noise cannot be heard in the car, which makes the car whistle sound that can be heard in the car smaller and smaller. Especially when driving at ...
