摘要： A vibration signal generation apparatus (60) and vibration signal generation program aim to output a vibration regardless of frequency characteristics of an acoustic signal. The vibration signal generation apparatus (60) includes an absolute value signal generator (300) configured to generate an absolute value signal by detecting an absolute value of amplitude of an acoustic signal, an envelope signal generator (300) configured to generate an envelope signal by detecting an envelope of the absolute value signal, a differentiator (400) configured to differentiate the envelope signal, an amplitude limiter (400) configured to generate an amplitude-limited signal by limiting amplitude of the envelope signal so that an amplitude value of the differentiated envelope signal becomes zero or greater, and a vibration signal generator (500) configured to generate a vibration signal by multiplying the amplitude-limited signal by a reference signal having a frequency that allows a human to perceive a vibration.

摘要： To allow the driver to identify a notification vibration even in a situation in which the notification vibration may be masked depending on the road conditions. A vehicle notification device (1) randomly extract one of a plurality of pieces of signal data by the number of vibrators (exciters EX1 to EX4), each of the pieces of signal data being different in a combination of an initial frequency and a target frequency and generates a plurality of sweep signals by changing the frequency from the initial frequency to the target frequency of the extracted piece of signal data in cycles. A plurality of notification vibrations whose frequencies change in different frequency ranges are outputted by outputting the generated sweep signals, individually from the vibrators (exciters EX1 to EX4).

摘要： To make a notification to the driver so that the driver can distinguish or recognize the notification. A vehicle notification device (1a) inputs a first sweep signal whose frequency is changed in a predetermined frequency range, to a vibrator (4), calculates frequency characteristics of a vibration in the vehicle interior, detects a frequency range in which the signal level of vehicle-travel-time frequency characteristics is higher than the signal level of vehicle-stop-time frequency characteristics by a predetermined level amount or more, generates a second sweep signal whose frequency is changed in a range obtained by excluding the detected frequency range from the predetermined frequency range of the first sweep signal, and outputs the second sweep signal from the vibrator (4).
