The invention discloses an electric vehicle low-speed alarm control system, a control method and a medium, and relates to the technical field of vehicles. The control system comprises a data acquisition unit configured to be used for acquiring vehicle speed information, vehicle surrounding environment information and vehicle surrounding sound information; the information processing module is configured to be used for converting the sound information around the vehicle into a frequency-sound pressure curve graph when it is judged that the low-speed alarm needs to play the prompt tone; when it is judged that the frequency peak value is within the preset frequency interval and the sound pressure level corresponding to the frequency peak value is larger than or equal to the sound pressure level of any frequency of the preset prompt tone, a characteristic frequency band is calculated; obtaining a characteristic frequency band range according to the characteristic frequency band and the frequency peak value; and the audio control module is configured to adjust and play the preset prompt tone when judging that the frequency of the preset prompt tone is within the characteristic frequency band range. The sound pressure level and frequency of the prompt tone are adjusted in real time according to different conditions, the masking effect of ambient noise around the vehicle is avoided, and the safety risk is effectively reduced.
本发明公开一种电动汽车低速报警器控制系统、控制方法及介质,涉及车辆技术领域。该控制系统包括:数据采集单元,配置用于采集车辆车速信息、车辆周围环境信息和车辆周围声音信息;信息处理模块,配置用于判定低速报警器需要播放提示音时,将车辆周围声音信息转换为频率‑声压曲线图;判断频率峰值处于预设频率区间内且频率峰值对应的声压级大于或者等于预设提示音任一频率的声压级时,计算特征频带;根据特征频带和频率峰值,得到特征频带范围;音频控制模块,配置用于判断预设提示音的频率处于特征频带范围内时,调整预设提示音并播放。针对不同情况实时调整提示音的声压级和频率,避开车辆周围的环境噪声的掩蔽效应,有效降低安全风险。
