Abstract

A hostless automobile reverse radar warning system installed to an automobile includes a reverse signal light power module for supplying an electric power required by the system, a plurality of distance sensing modules installed to an external periphery of the automobile for performing a distance detection to detect external environment conditions of the automobile, producing a distance detection result, and generating a warning signal based on the distance detection result, and a warning module for receiving the warning signal and producing a sound to alert a driver based on the warning signal.

Claims

1. A hostless automobile reverse radar warning system, installed to an automobile, and comprising:

a reverse signal light power module, for supplying an electric power required by the system;

a plurality of distance sensing modules, installed to an external periphery of the automobile by a parallel connection of circuits, for receiving the electric power, performing a distance detection to detect external environment conditions of the automobile and produce a distance detection result, and generating a warning signal based on the distance detection result; and

a warning module, for receiving the warning signal, and producing a sound to alert a driver based on the warning signal.

2. The hostless automobile reverse radar warning system of claim 1, wherein each distance sensing module comprises an ultrasonic unit and a processing unit, and the ultrasonic unit is provided for performing the distance detection to detect the external environment conditions of the automobile, produce the distance detection result, and transmit the distance detection result to the processing unit for processing, so as to generate the warning signal and output the warning signal.

3. The hostless automobile reverse radar warning system of claim 1, wherein the distance sensing modules are installed equidistantly along the external periphery of the automobile.

4. The hostless automobile reverse radar warning system of claim 1, wherein the warning module is a buzzer.
