1. A motion-sensing in-vehicle alerting method, applied to a vehicle with an excitation oscillator fixed to a seat of the vehicle, comprising:
obtaining, by a controller, an audio signal from an in-vehicle audio bus;
performing an acoustic characteristics analysis on the audio signal, and extracting an acoustic waveform of the audio signal in a time domain waveform;
performing an amplitude modulation on a sinusoidal signal of the acoustic waveform to obtain a modulated sinusoidal signal after amplitude modulation;
obtaining, by the controller, a control signal indicating operational behavior information from an in-vehicle control bus, matching the control signal with the modulated sinusoidal signal according to a predetermined rule to generate a vibration signal, and transmitting the vibration signal to the excitation oscillator to achieve a vibration alert.
