Claims

[Scope of utility model registration request]

A device that uses ultrasonic waves or radio waves to detect the distance between vehicles in front while driving, and issues an alert when the detected distance falls below the braking distance calculated based on the vehicle speed of your own vehicle. A vehicle alarm system comprising a setting means for individually setting each of the braking range speed of the own vehicle, the minimum inter-vehicle distance when the own vehicle is stopped by braking, and the response time of brake operation. .
