The invention discloses a vehicle control system based on auditory perception of road conditions. The vehicle control system comprises a sound sensor array, a preprocessing module, a signal buffer module, a signal processing module, a function implementation module and a control unit, the sound sensor array comprises a plurality of sound sensors arranged at different positions of a vehicle in an array mode and is used for collecting sound signals generated when vehicle tires roll on the road surface. The preprocessing module is used for preprocessing the sound signal; the signal buffer module is used for aligning multiple paths of sound signals according to a time sequence and setting a storage threshold value to prevent data in a memory from overflowing; the signal processing module is used for performing signal segmentation processing on the sound signals to output frame information, and then performing feature extraction processing on the frame information to extract different frequency band feature quantities to obtain feature parameters reflecting sound signal features; and the function realization module is used for realizing sensing of a driving road surface state and tire pressure.

    本发明的一种基于道路状况听觉感知的车辆控制系统,包括声音传感器阵列、预处理模块、信号缓冲模块、信号处理模块、功能实现模块和控制单元;声音传感器阵列包括阵列布置在车辆不同位置的多个声音传感器,用于采集车辆轮胎在路面上滚动产生的声音信号;预处理模块用于对声音信号进行预处理;信号缓冲模块用于将多路声音信号按时序对齐,设置存储阈值以防止内存中的数据溢出;信号处理模块用于对声音信号进行信号分段处理以输出帧信息,然后对帧信息进行特征提取处理以提取不同频段特征量,得到反映声音信号特征的特征参数;功能实现模块用于实现行驶路面状态和轮胎气压的感知。
