Abnormality reporting device for vehicle and control program
View Patent ↗There are provided an abnormality reporting device that can generate vibration which can be easily perceived by a driver even when the driver is in a vibrating vehicle during running, and a control program therefore. The abnormality reporting device is equipped with a detector 2 for detecting the state of a driver 10 or the state of a vehicle 20 as a prescribed state when the vehicle 20 is moving, a judging unit 4 for judging on the basis of the detection result of the detector 2 whether it is under an abnormal state, and a vibrating unit 8 for applying vibration of a predetermined vibration pattern to the driver 10 when the abnormality state is judged, and the vibrating unit 8 can apply the vibration while varying the vibration pattern when the abnormality state is continued.
1. An abnormality reporting device for a vehicle, comprising:
a detector configured to detect the state of a driver or the running state of a vehicle while the vehicle is running;
a judging unit configured to judge on the basis of a detection result of the detector whether the state of the driver or the state of the vehicle is under an abnormal state; and
a vibrating unit configured to apply vibration having a predetermined vibration pattern to the driver when the abnormal state is judged,
wherein the vibrating unit is configured to apply the vibration while varying the vibration pattern when the abnormal state is continued,
wherein the vibrating unit is configured to apply a vibration on the basis of a plurality of pulses while varying a vibration pattern of the vibration when the abnormal state is continued,
wherein each of the plurality of pulses comprises a pulse wave, and
wherein the vibrating unit configured to apply the vibration while continuously varying the frequency and amplitude of each pulse wave during a period when each pulse occurs.
2. The vehicle abnormality reporting device according to claim 1 , wherein the vibrating unit continuously varies the frequency of the vibration when the vibration pattern is varied.
3. The vehicle abnormality reporting device according to claim 1 , wherein the vibrating unit continuously or stepwise varies the amplitude of the vibration when the vibration pattern is varied.
4. The vehicle abnormality reporting device according to claim 1 , wherein the vibrating unit varies the vibration applying interval when the vibration pattern is varied.
5. The vehicle abnormality reporting device according to claim 1 , wherein the vibration obtained by the vibration pattern is a one-shot vibration.
6. The vehicle abnormality reporting device according to claim 1 , wherein the judging unit judges the abnormal state when the detection result of the detector indicates that the driver is under a nap state.
7. The vehicle abnormality reporting device according to claim 1 , wherein the judging unit judges the abnormal state when the detection result of the detector indicates that the vehicle deviates from a white line.
8. The vehicle abnormality reporting device according to claim 1 , wherein the vibrating unit is disposed at a seat in which the driver sits.
9. The vehicle abnormality reporting device according to claim 1 , wherein the vibrating unit is equipped with a speaker for converting an electrical signal to the vibration.
10. The vehicle abnormality reporting device according to claim 1 , further comprising a vehicle speed detector for detecting the speed of the vehicle, wherein the vibrating unit varies the vibration pattern in accordance with the detected speed.
11. The vehicle abnormality reporting device according to claim 10 , wherein when the vibration pattern is varied, the vibrating unit lengthens an initial driving interval if the detected speed is low, and shortens the initial driving interval if the detected speed is high.
12. The vehicle abnormality reporting device according to claim 10 , wherein the vibrating unit varies initial vibration intensity in accordance with the detected speed when the vibration pattern is varied.
13. The vehicle abnormality reporting device according to claim 1 , wherein the frequency and amplitude of each pulse wave are continuously varied every pulse wave.
