Alarm device, alarm method and non-transitory recording medium

An alarm method comprising:

• determining whether a state of a driver is an inappropriate state to generate vibration of a predetermined intensity in a seat belt or to apply tension of a predetermined intensity to the seat belt, based on an in-vehicle sensor signal, the in-vehicle sensor signal being a driver image;
• determining whether a situation requiring notification of a predetermined warning to the driver occurs, based on at least one of an out-of-vehicle sensor signal, a behavior sensor signal, the in-vehicle sensor signal, and a current location of a vehicle, the vehicle having a user interface configured to receive an input of the driver;
• notifying the driver of the predetermined warning by generating the vibration of the predetermined intensity in the seat belt or by applying the tension of the predetermined intensity to the seat belt when the situation requiring the notification of the predetermined warning occurs and when the state of the driver is not an inappropriate one;
• notifying the driver of the predetermined warning by one of generating the vibration of an intensity weaker than the predetermined intensity in the seat belt, applying the tension of an intensity weaker than the predetermined intensity to the seat belt, and using a notification unit other than the seat belt when the situation requiring the notification of the predetermined warning occurs and when the state of the driver is an inappropriate one, or stopping the notification of the predetermined warning when the situation requiring the notification of the predetermined warning occurs and when the state of the driver is an inappropriate one;
• and
• executing processing according to a request of the driver when the situation requiring the notification of the predetermined warning occurs, when the state of the driver may be an inappropriate one, and when the user interface receives the request of the driver,
• wherein the user interface is configured to receive the input of the driver requesting that the predetermined warning is notified to the driver by one of generating the vibration of the intensity weaker than the predetermined intensity in the seat belt, applying the tension of the intensity weaker than the predetermined intensity to the seat belt, and using the notification unit other than the seat belt or that the notification of the predetermined warning is stopped, when the situation requiring the notification of the predetermined warning occurs and when a state determination unit determines that the state of the driver may be an inappropriate one based on the driver image.

A non-transitory recording medium having recorded thereon a computer program for causing a processor to execute a process comprising:

• determining whether a state of a driver is an inappropriate state to generate vibration of a predetermined intensity in a seat belt or to apply tension of a predetermined intensity to the seat belt, based on an in-vehicle sensor signal, the in-vehicle sensor signal being a driver image;
• determining whether a situation requiring notification of a predetermined warning to the driver occurs, based on at least one of an out-of-vehicle sensor signal, a behavior sensor signal, the in-vehicle sensor signal, and a current location of a vehicle, the vehicle having a user interface configured to receive an input of the driver;
• notifying the driver of the predetermined warning by generating the vibration of the predetermined intensity in the seat belt or by applying the tension of the predetermined intensity to the seat belt when the situation requiring the notification of the predetermined warning occurs and when the state of the driver is not an inappropriate one;
• notifying the driver of the predetermined warning by one of generating the vibration of an intensity weaker than the predetermined intensity in the seat belt, applying the tension of an intensity weaker than the predetermined intensity to the seat belt, and using a notification unit other than the seat belt when the situation requiring the notification of the predetermined warning occurs and when the state of the driver is an inappropriate one, or stopping the notification of the predetermined warning when the situation requiring the notification of the predetermined warning occurs and when the state of the driver is an inappropriate one;
• and
• execute processing according to a request of the driver when the situation requiring the notification of the predetermined warning occurs, when the state of the driver may be an inappropriate one, and when the user interface receives the request of the driver,
• wherein the user interface is configured to receive the input of the driver requesting that the predetermined warning is notified to the driver by one of generating the vibration of the intensity weaker than the predetermined intensity in the seat belt, applying the tension of the intensity weaker than the predetermined intensity to the seat belt, and using the notification unit other than the seat belt or that the notification of the predetermined warning is stopped, when the situation requiring the notification of the predetermined warning occurs and when a state determination unit determines that the state of the driver may be an inappropriate one based on the driver image.
