  • Security-feature-equipped on-vehicle device and security-feature control method of on-vehicle device
    Patent number: 8120475
    Abstract: A security-feature-equipped on-vehicle device includes: a vibration detection unit that detects vibration; an alarm sound output unit that outputs a predetermined alarm sound from a speaker; and an alarm sound control unit that going outs from a sleep mode to move into a warning mode when vibration is detected for the first time by the vibration detection unit, causes the alarm sound output unit to output the alarm sound at a predetermined first volume level, shifts from the warning mode into an alarm mode when vibration is detected for the second time within a predetermined time period, and causes the alarm sound output unit to output the alarm sound at a predetermined second volume level higher than the first volume level.
