DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, specific embodiments of the present invention will be described below with reference to the accompanying drawings. It is obvious that the drawings in the following description are only some embodiments of the invention, and that for a person skilled in the art, other drawings and embodiments can be obtained from them without inventive effort.
An embodiment of the utility model provides an automobile rear blind spot monitoring system, as shown in fig. 1, include in this monitoring system 100:
a millimeter wave radar 110 provided on the rear bumper of the automobile for detecting toward the rear and the side of the automobile;
the TPMS120 is arranged in the tire and is used for monitoring the running speed of the automobile in real time;
a TPMS wireless receiver 130 communicatively connected to the TPMS120, configured to receive monitoring data sent by the TPMS 120;
a radar control box 140 connected to the millimeter wave radar 110 and the TPMS wireless receiver 130, respectively, for receiving the detection signal of the millimeter wave radar 110 and the running speed of the automobile, determining whether a moving object is approaching, and determining an approaching direction when it is determined that a moving object is approaching;
and the alarm device 150 is connected with the radar control box 140 and used for giving corresponding alarms according to the judgment result of the radar control box 140.
In this embodiment, the millimeter-wave radar 110 is installed on the rear bumper of the vehicle, and two sides of the millimeter-wave radar are respectively installed, wherein the millimeter-wave radar comprises a left radar and a right radar. The TPMS120 is installed in at least one tire, the running speed of the automobile is monitored in real time in the running process of the automobile, the tire pressure and the temperature of the tire are monitored, monitoring data are sent to the radar control box 140 through the TPMS wireless receiver 130, then the radar control box 140 analyzes and displays the received monitoring data, whether the tire works normally or not is judged, and whether the tire needs to be replaced or not is judged (the monitoring data and the prediction on whether the tire needs to be replaced or not are displayed through a display screen). In one example, a TPMS is provided in each tire of an automobile and monitored. The monitoring frequency of the tire pressure and the temperature in the TPMS tire is set according to the actual situation, such as monitoring once every 5 minutes, monitoring once every 1 hour and the like.
In the working process, after the millimeter wave radar 110 is started, the rear and the side of the automobile are detected, and the detected detection signals are sent to the radar control box 140 in real time; meanwhile, the TPMS120 detects the running speed of the car in real time and transmits it to the radar control box 140. The radar control box 140 receives the detection signal and the vehicle running speed and then starts data processing to judge whether a moving object which can cause a security threat to the vehicle is close to the rear. When the mobile object is judged to be close to the vehicle, the vehicle gives an alarm to prompt a driver to drive carefully, so that traffic accidents are avoided. In the automobile rear blind spot monitoring system 100, the detection of the millimeter wave radar 110 and the monitoring of the TPMS120 are combined, the alarm of the conditions of the coming automobile and the like at the rear is realized, and the purpose of automobile rear monitoring can be realized without dismounting a center console and an instrument panel and cracking a can bus.
The embodiment is improved, and in the embodiment, in the radar control box 140, whether the vehicle is in a moving state is judged according to the detected distance of the object and the running speed of the vehicle; and when the detected object is judged to be in a moving state and the relative distance is gradually reduced, judging that the moving object is in a close state, and further judging the close direction of the moving object in the close state.
In the working process, after the millimeter wave radar 110 is started, the rear and the side of the automobile are detected, and the detected detection signals are sent to the radar control box 140 in real time; meanwhile, the TPMS120 detects the running speed of the car in real time and transmits it to the radar control box 140. The radar control box 140 receives the detection signal and the vehicle running speed, and then starts to process data, respectively filters the detection signal and the speed signal, and filters an obvious noise signal. Then, whether the detected object threatens the automobile is analyzed, specifically, whether the object is in a moving state is judged according to the detection information and the automobile running speed, and if the object is in a static state, subsequent processing is not carried out; if the mobile object is in the motion state, whether the mobile object is in the approaching state or not is further judged according to the relative distance between the mobile object and the automobile, and if the mobile object is farther away from the automobile, the mobile object is judged not to cause danger to the automobile and is not subjected to subsequent processing; if the automobile is closer to the automobile, the automobile is judged to be in a close state, danger is possibly caused to the automobile, then the mobile object is continuously monitored, and when the relative distance between the mobile object and the automobile reaches a preset distance threshold value, a warning is given out to remind a driver. The distance threshold is preset according to the position of the moving object relative to the automobile, for example, the distance threshold is set to be 1 meter when the moving object and the automobile are behind; when the moving object is on the side of the automobile (including the left side and the right side), the distance threshold value is set to 0.5 m or the like, and can be adjusted according to the actual situation.
In the process of judging whether the detected object is in a moving state, the judgment is carried out according to the distance between the detected object and the running speed of the automobile, and specifically, the moving speed, the angle and the distance information of the detected object are obtained through direct test and check calculation of millimeter waves sent and received by a radar (Doppler principle). In this example, whether the moving object is in the approaching state is judged according to the distance of the moving object detected in real time. In other examples, the judgment can also be carried out through the moving speed of the moving object, and when the speed of the moving object is greater than the driving speed of the automobile, the judgment can cause danger to the automobile; when the speed of the moving object is judged to be not much different from the speed of the automobile or even smaller than the speed of the automobile, the automobile is judged not to be dangerous and is not subjected to subsequent treatment. For example, in one example, when the current speed of the automobile is 60 yards and the speed of the mobile object is 80 yards, it is determined that the mobile object may cause a danger to the automobile, and a warning is issued to remind the driver.
The above embodiment is modified to obtain the present embodiment, in which the alarm device 150 includes a left alarm lamp mounted on the left side mirror of the automobile, a right alarm lamp mounted on the right side mirror of the automobile, and a buzzer, and the left alarm lamp, the right alarm lamp, and the buzzer are respectively connected to the radar control box 140.
