The invention discloses an electric vehicle and a low-speed prompt sound system. The system comprises a loudspeaker, a multimedia assembly and a bass prompt unit, the multimedia assembly comprises a multimedia host, the multimedia host is connected with a whole vehicle CAN network through a CAN bus to obtain whole vehicle gear information and vehicle speed information, and the whole vehicle gear information and the vehicle speed information are sent to the bass prompt unit; and the bass prompt unit sends a sound source calling instruction to the multimedia host when judging that the electric vehicle currently meets a sound production condition, so that the multimedia host returns audio data, generates an audio driving signal according to the audio data, and sends the audio driving signal to the multimedia host, so that the multimedia host drives the loudspeaker to give out a low-speed prompt sound, and the software part of the bass prompt unit and the software part of the multimedia host are mutually independent. Therefore, a bass prompt controller does not need to be additionally arranged, the integration level is high, the software part of the bass prompt unit is independently designed, and the universality is high.

    本发明公开了一种电动车及低速提示音系统,其中,系统包括扬声器、多媒体总成和低音提醒单元,其中,多媒体总成包括多媒体主机,多媒体主机通过CAN总线连接到整车CAN网络,以获取整车档位信息和车速信息,并发送给低音提醒单元;以及,低音提醒单元在判断电动车当前满足发声条件时向多媒体主机发送音源调用指令,以便多媒体主机返回音频数据,以及根据音频数据生成音频驱动信号,并发送给多媒体主机,以便多媒体主机驱动扬声器发出低速提示音,其中,低音提醒单元的软件部分与多媒体主机的软件部分之间相互独立。由此,无需额外设置低音提醒控制器,集成度高,且低音提醒单元软件部分独立设计,通用性强。
