fig. 2 is a schematic view of the usage flow of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below. It should be understood, however, that the description herein of specific embodiments is only intended to illustrate the invention and not to limit the scope of the invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, and the terms used herein in the specification of the present invention are for the purpose of describing particular embodiments only and are not intended to limit the present invention.
As shown in fig. 1, a rear vehicle collision warning system includes a vehicle body controller (hereinafter referred to as BCM) and a double-side turn signal lamp (hereinafter referred to as hazard warning lamp), and further includes a millimeter wave radar, a warning controller and an instrument buzzer;
the millimeter wave radar is connected with the early warning controller through a wire harness, the early warning controller is connected with the BCM through the wire harness, and the BCM is respectively connected with the danger warning lamp and the instrument buzzer through the wire harness;
the millimeter wave radar is used for monitoring the distance between the vehicle and the rear vehicle when the vehicle is in a running state;
the early warning controller is used for receiving a vehicle distance signal in a running state and judging a vehicle speed signal, and when the rear vehicle speed is greater than the vehicle and the vehicle distance is lower than a set safety value, the early warning controller transmits an alarm signal;
and the BCM is used for receiving the alarm signal and controlling a danger warning lamp and an instrument buzzer to send out alarm information.
The rear vehicle collision early warning system can effectively inform the information of the vehicle distance state to the driver and passengers in time, reduce the accident occurrence probability and reduce the casualties and the economic loss.
As an improvement of the embodiment, the millimeter wave radar adopts a 77GHZ millimeter wave radar, the model can adopt a CTRLRR-320, the monitoring precision is high, and the monitoring real-time performance is improved; in addition, the millimeter wave radar is installed on the rear bumper of the vehicle, and the installation position is concealed, so that the service life can be effectively prolonged, and the millimeter wave radar is not easy to damage.
