The invention relates to a method for detecting a vibration warning signal of a steering wheel of an automobile, which comprises the following steps of: acquiring a vibration signal of the steering wheel through a sensor fixed on the steering wheel, transmitting the acquired vibration signal to a data processing device through a cable, and identifying the vibration warning signal of the steering wheel in a frequency domain after analytical operation; and the detection device detects the vibration signal of the steering wheel in real time, and accurately detects whether the vibration warning signal of the steering wheel is generated or not and the generation time. The method can directly collect the vibration signal of the steering wheel and process the vibration signal in real time. The characteristic frequency obtained through frequency domain analysis is used as a judgment basis of signal emission, and whether the vibration warning signal of the steering wheel occurs or not and the occurrence time can be directly, accurately and objectively detected. The objectivity and the accuracy of steering wheel vibration signal detection of an intelligent network connection automobile driving assistance function in a related scene are met.

    本发明涉及一种汽车方向盘振动警示信号的检测方法,通过固定在方向盘上的传感器采集方向盘的振动信号,采集的振动信号通过电缆传输给数据处理装置,经过解析运算后在频域上识别方向盘振动警示信号,并由检测装置对方向盘振动信号实时检测,准确地检测方向盘振动警示信号是否发生以及发生的时刻。本方法可以直接采集方向盘振动信号,并实时处理。通过频域分析得到的特征频率作为信号发出的判定依据,可以直接、准确、客观地检测方向盘振动警示信号是否发生,以及发生的时刻。满足智能网联汽车驾驶辅助功能在相关场景下,方向盘振动信号检测的客观性和准确性。
