To provide a vehicle alarm device, a vehicle alarming method and a vehicle alarm generation program, capable of describing driving characteristics of a driver in detail and generating an alarm at appropriate timing, without specifying a deceleration starting operation and the time when a driver is aware of the necessity of deceleration. An alarm determination unit refers to alarm speed data in an alarm speed database and obtains an alarm speed data value corresponding to the distance to an object recognized by an object recognition unit, and then compares the alarm speed data value with a current speed of the own vehicle outputted by a speed measurement unit. If the own vehicle speed exceeds the alarm speed data value, the alarm determination unit determines that it is an abnormal state where the driver is not aware of a "red light" or a "stop sign".
