Claims

[Scope of utility model registration request]

A stop and start warning is provided by comparing the output of the following distance sensor, which non-contact measures the distance between the vehicle in front and the vehicle in front, with each standard value set separately for when the vehicle in front is moving and when the vehicle in front is starting. an alarm trigger circuit that outputs a trigger signal;
A vehicle speed sensor that electrically detects the vehicle running speed, a stopped running determination circuit that uses the output of the vehicle speed sensor to determine whether the vehicle is running or stopped, a braking detector that detects a brake operation of the vehicle, and the alarm trigger circuit. Using each output signal of the stop running discrimination circuit and the brake detector, a stop warning signal is output when the distance between the vehicle in front becomes less than a set distance when the brake is released while the vehicle is moving, and when the vehicle is stopped. The vehicle includes an arithmetic circuit that outputs a start warning signal when the vehicle in front starts moving and the following distance exceeds a set distance in a braked state, and an alarm device that issues a warning to the driver based on the alarm signal from the arithmetic circuit. Vehicle forward monitoring device.
