In addition, when the automobile runs, the left and right radar modules are started, the condition behind the automobile is monitored, if the automobile is in the rear part, signals are fed back to the control module, when the left radar detects that the distance between the automobile and other objects is within 10 meters, the control module sends out control signals, the left warning lamp is normally on, and the buzzer does not sound. If the lane is to be changed to the left and the left steering lamp is turned on, the system sends out an alarm signal, the left LED flashes and the buzzer alarms. The same is true for the right lane change. When backing a car, the back-up light is bright, and left and right radar module starts, the condition at monitoring rear, and the magic that backs a car simultaneously inputs control module, and control module enters into the magic of backing a car and calculates, if the distance has the car transversely to enter into the detection scope in 3m, the probe gives information feedback to control module, and control module output alarm signal controls the warning light scintillation, and buzzer warning realizes the blind spot monitoring early warning when backing a car.
When the automobile is stopped and flamed out, the power supply can be kept, and the device can be used for monitoring and early warning of radar. When the vehicle door is opened, a signal is fed back to the control module from the left door opening signal end or the right door opening signal end to trigger the door opening signal circuit, the radar is started, when a person or a vehicle is behind, the distance between the left door opening signal end and the right door opening signal end is fed back to the control module, if the distance is within 15m, the left warning lamp/the right warning lamp flickers, and the buzzer gives an alarm (high frequency) to remind the person not to open the door and get off the vehicle; the safety of drivers and passengers is guaranteed.
