Claims (1)

[Scope of Claim for Utility Model Registration] (1) Discrimination means that measures the distance between the vehicle in front and the vehicle in front, compares the distance between the vehicles with a predetermined distance set in advance, and outputs a binary discrimination signal; A case in which a change from the second value of the discrimination signal to the first value occurs after a first predetermined period has elapsed from the time when the latest change from the first value to the second value of the discrimination signal occurs; , a change from the first value of the discrimination signal to the second value occurs after a second predetermined period has elapsed from the time of occurrence of the latest change from the second value of the discrimination signal to the first value. What is claimed is: 1. An inter-vehicle distance warning device comprising: warning generating means for generating a warning in at least one of the following cases. (2) Discrimination means for measuring the distance between the vehicle in front of the vehicle in front, comparing the distance between the vehicles and a predetermined distance set in advance, and outputting a binary discrimination signal; When a change in the discrimination signal from the second value to the first value occurs after a predetermined period of time has elapsed since the latest change to the second value, an alarm is generated to give a warning to the driver of the following vehicle. An inter-vehicle distance warning device comprising: means.
