The invention relates to the technical field of vehicles, in particular to a vehicle driving warning sound generation method and device, equipment and a storage medium. Environment bottom noise data is obtained through real-time collection and analysis, and a frequency band possibly generating a masking effect on the generated warning sound is judged according to the data; in particular, the system recognizes the frequency bands influenced by the masking effect according to the spectral characteristics of the environmental noise, and increases the volume of the frequency bands in a targeted manner to ensure that the warning sound can be effectively transmitted to pedestrians, and in addition, the system also can give the warning sound to the pedestrians according to the actual driving scene of the vehicle. According to the method, the most appropriate warning sound frequency band and gain parameters can be intelligently selected to adapt to different acoustic environments, such as an underground garage or an open parking lot, so that the pedestrian warning effect when the electric vehicle runs at a low speed is remarkably improved.
本发明涉及车辆技术领域,尤其涉及车辆行驶警示音生成方法、装置、设备及存储介质,本申请通过实时采集并分析得到环境底噪数据,并依据此数据判断可能对生成的警示音产生掩蔽效应的频段,然后针对性的对这些频段的警示音进行增益,具体来说,系统会根据环境噪声的频谱特性,识别出受掩蔽效应影响的频段,并针对性地增加这些频段的音量,以确保警示音能够有效传达给行人,此外,系统还会根据车辆的实际行驶场景,如地下车库或露天停车场,智能选择最合适的警示音频段和增益参数,以适应不同的声学环境,从而显著提高了电动汽车在低速行驶时的行人警示效果。
