The invention discloses a system for achieving low-speed warning tone AVAS and active sound enhancement ASE on an automobile, low-speed warning tone and active sound enhancement processing is carried out through cooperation of two processing units, and a low-speed warning tone and active sound enhancement function is achieved in cooperation with a rear-end AVAS module. When the system realizes the low-speed warning tone function, an additional analog audio channel specially used for a low-speed warning tone loudspeaker does not need to be configured in the same vehicle machine system device, and the rear-end AVAS module realizes the low-speed warning tone function in a mode of sharing a certain in-vehicle analog audio channel and using an independent PWM (Pulse Width Modulation) transmission channel. And the system has the functions of judging and switching working modes. The sound generated by the system can be changed and matched along with the change of the vehicle state and the driving style of the user, so that information is effectively transmitted to other road users, and the sound perception in the driving process is enhanced or changed.
本发明公开一种用于在汽车上实现低速提示音AVAS和主动声增强ASE的系统,通过两个处理单元协同进行低速提示音和主动声增强处理,并配合后端AVAS模块实现低速提示音和主动声增强功能。该系统实现低速提示音功能时无需在同一车机系统装置中配置额外的专供低速提示音扬声器使用的模拟音频通道,后端AVAS模块采用共用某一路车内模拟音频通道和使用单独的PWM脉宽调制传输通道相结合的形式实现低速提示音功能,并具备工作模式判断与切换功能。采用该系统生成的声音可随车辆状态及用户驾驶风格的变化而改变和匹配,从而有效地传递信息给其他道路使用者并增强或改变驾乘过程中声音感知。
