Automobile and reminding system and method for sounds outside automobile

Abstract

The invention discloses an automobile and a reminding system and method for sounds outside the automobile. The system comprises a sound recognition device, a sound conversion device and a vehicle-mounted reminding device. The sound recognition device is used for receiving and recognizing the sounds outside the automobile, converting the sounds outside the automobile into corresponding sound signals and screening out sound signals meeting preset conditions. The sound conversion device is used for receiving the sound signals meeting the preset conditions and converting the received sound signals into corresponding analytic signals. The vehicle-mounted reminding device is used for receiving the analytic signals and converting the analytic signals into corresponding reminding signals. The automobile, especially, an automobile with good NVH performance can recognize, transmit and convert sounds outside a cab and remind a driver to pay attention to the driving environment, then the driver can make corresponding response according to actual conditions, and accordingly driving safety of the driver is guaranteed.

Description

technical field [0001] The invention relates to the field of automobile information systems, in particular to an automobile and its external sound prompt system and method. Background technique [0002] With the development of science and technology, the performance of automobiles has become more and more complete, and people have paid more and more attention to the comfort of driving and riding. [0003] In the development of automobiles, automobile noise is a problem that people are widely concerned about. During driving, the noise will give the driver and passengers a bad driving experience. Therefore, the research and improvement of NVH performance by automobile research and development institutions are also more in-depth. , where NVH refers to noise, vibration and harshness, which makes the environment inside the car more and more "quiet", but at the same time reduces the recognition of external sounds inside the car, which is beneficial to the sound outside the car ( ...

Problems solved by technology

[0003] In the development of automobiles, automobile noise is a problem that people are widely concerned about. During driving, the noise will give the driver and passengers a bad driving experience. Therefore, the research and improvement of NVH performance by automobile research and development institutions are also more in-depth. , where NVH refers to noise, vibration and harshness, which makes the environment inside the car more and more "quiet", but at the same time reduces the recognition of external sounds inside the car, which is beneficial to the sound outside the car ( Such as vehicle whistle, etc.) are also shut out, so that users cannot pay attention to the environment outside the vehicle in time, which is likely to cause traffic accidents

For example, when the vehicle has a blind spot and cannot observe the situation when the vehicle is turning at a right angle, or the driver is not focused and there are other vehicles overtaking behind, other vehicles or the driver of the vehicle cannot obtain the horn information in time, which may easily lead to traffic accidents
