The invention discloses a control system and method integrating pedestrian warning sound and engine sound functions. The control system comprises an MCU1, a CAN signal transceiver 2, an audio processing device, a CPU and an audio playing device, wherein the CAN signal transceiver 2 and the audio processing device are connected with the MCU1. According to the technical scheme, vehicle speed, gear information and accelerator pedal position information are read from the CAN bus through the MCU module, signals are output to the loudspeaker after calculation of the audio processor, and the purpose of combining sound of engines inside and outside the vehicle and warning sound of pedestrians outside the vehicle is achieved. The control of engine sound inside and outside the vehicle and pedestrian warning sound outside the vehicle is realized through one control module, the upgrading and maintenance are convenient, the real-time performance of control is met, and the cost of the system is reduced.
本发明公开了一种集成行人警示音与引擎声浪功能的控制系统及方法,包括MCU1和分别与MCU1相连的CAN信号收发器2、音频处理装置,以及CPU与音频播放装置。上述技术方案通过MCU模块从CAN总线读取车速、档位信息和油门踏板位置信息,在音频处理器通过计算后输出信号到扬声器,实现将车内外引擎声浪和车外行人警示音结合起来的目的,通过一个控制模块实现车内外引擎声浪和车外行人警示音的控制,同时达到升级和维护方便,满足控制的实时性同时降低系统的成本。
