Vehicle alarm device, vehicle alarming method, and vehicle alarm generation program
First Claim
1. An alarm device for a vehicle comprising:
- an object detection unit for detecting an object existing ahead of the vehicle, and measuring a distance to the object;
a speed measurement unit for measuring a speed of the vehicle;
an alarm speed database for holding alarm speed data expressing a nonlinear deceleration operation, substantially matching the individual driving characteristics of the driver, with respect to the distance from the vehicle to the object, and the speed of the vehicle;
an alarm determination unit for obtaining a speed corresponding to a distance to the object at a current time by referring to the alarm speed data and setting it as an alarm speed value at the current time, and if the speed of the vehicle at the current time exceeds the alarm speed value, determining a state as abnormal; and
alarm output unit for outputting an alarm when the alarm determination unit determines the state as abnormal.

Abstract
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”.

10. An alarming method for a vehicle comprising the steps of:
-
detecting an object existing ahead of the vehicle, and measuring a distance to the object; measuring a speed of the vehicle; and setting a speed corresponding to the distance to the object as an alarm speed value at a current time by referring to an alarm speed database including alarm speed data expressing a nonlinear deceleration operation, substantially matching the individual driving characteristics of the driver, with respect to a distance to the object and the speed of the vehicle, and if the speed of the vehicle at the current time exceeds the alarm speed value, determining a state as abnormal; and outputting an alarm when the state is abnormal. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. An alarm generation program for a vehicle for prompting a computer to perform:
-
a function of an object detection unit for detecting an object existing ahead of the vehicle and measuring a distance to the object; a function of a speed measurement unit for measuring a speed of the vehicle; a function of an alarm determination unit for extracting a speed corresponding to the distance to the object and setting it as an alarm speed value at a current time by referring to an alarm speed database including alarm speed data expressing a nonlinear deceleration operation, substantially matching the individual driving characteristics of the driver, with respect to a distance to the object and the speed of the vehicle, and when the speed of the vehicle at the current time exceeds the alarm speed value determining a state as abnormal; and a function of an alarm output unit for outputting an alarm when the alarm determination unit determines the state as abnormal. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
