The invention discloses an active control system and method for automobile road noise and a vehicle, and the system comprises a passenger recognition system which is configured to recognize an internal environment signal of the vehicle; the vibration pickup system is configured to collect vehicle body vibration signals in real time; a CAN input system configured to output a signal for a vehicle state; the noise pickup system is configured to collect environment noise signals in the vehicle in real time; a controller system configured to generate a noise control signal by applying the convergence coefficient to an active road noise control unit according to the passenger head information, according to the vibration signal, according to the noise reduction system function signal, and according to the in-vehicle noise signal; and a noise output system configured to output the noise control signal. According to the method, the noise of the target position can be accurately reduced, the noise reduction performance is improved, the adaptability of the noise reduction performance and the system convergence speed are improved, and the stability of a road noise active control system is improved.

    本发明公开了一种针对汽车路噪主动控制的系统、方法及车辆,包括乘客识别系统,其配置为识别车辆内部环境信号;振动拾取系统,其配置为实时采集车体振动信号;CAN输入系统,其配置为车辆状态输出信号;噪声拾取系统,其配置为实时采集车辆内部环境噪声信号;控制器系统,其配置为根据所述乘客头部信息、根据所述振动信号、根据所述降噪系统功能信号、根据所述车内噪声信号、通过将所述收敛系数应用于主动路噪控制单元生成噪声控制信号;以及噪声输出系统,其配置为输出所述噪声控制信号。本发明可精准降低目标位置噪声,提高了降噪性能,提高了降噪性能的适应性和系统收敛速度,提高了路噪主动控制系统的稳定性。
