Abstract
Disclosed are a motion-sensing in-vehicle alerting method, a system, and a related device, which are applied to vehicles. The method includes steps of: 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. The method of the present application not only enhances safety, but also provides the vibration alert, resulting in an improved user experience.
