Problems solved by technology
This kind of product has a simple structure and can be a self-contained system, which can complete the monitoring and alarm functions independently. The signal range emitted by this kind of product is fixed, and its function and work control have nothing to do with the state of the vehicle. Therefore, the real-time and Security is insufficient

Embodiment Construction
[0023] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0024] Such as figure 1 and figure 2 As shown, the vehicle blind spot dynamic monitoring system of the present invention is divided into a two-layer control management framework, wherein, the BCM body controller 1, the driving sensor and the blind spot monitoring sound and light alarm device 2 are the main control layer, the signal preprocessing unit 3 and the blind spot probe 4 It is the sub-control layer, and the data exchange and control management between the main control layer and the sub-control layer are completed through the body CAN / LIN communication network.
[0025] The blind spot probe 4 is arranged on both sides of the vehicle body. In the present embodiment, the blind spot probe 4 includes a left blind spot ultrasonic probe and a rig...

The invention discloses a dynamic monitoring system and method for a dead zone of a vehicle. According to the dynamic monitoring system for the dead zone of the vehicle, real-time monitoring, dynamic analysis and sound-light alarming are carried out on adjacent lanes and the vehicles in the adjacent lanes according to vehicle operation parameters, driving states, road conditions and driving purposes of drivers; the monitoring system is used for dynamically adjusting excitation signals of ultrasonic probes on the two sides of a vehicle body so that different detection regions can be obtained; a signal preprocessing unit is used for carrying out signal to noise ratio evaluation on weak obstacle reflection wave signals received by the probes, and carrying out gain adjustment on signal amplification circuit in the probes so as to obtain echo signals with higher signal to noise ratios. According to the dynamic monitoring system and method for the dead zone of the vehicle, a main control framework and a secondary control framework of the system can be used for processing related signals of sensors on the vehicle body respectively so that blind zone rapid detection, dynamic adjustment, target tracking, zone alarming and dead zone safe warning functions under different road conditions, different weathers and different driving conditions can be realized.
Description
technical field [0001] The invention relates to the field of safe driving of automobiles, in particular to a dynamic monitoring system and method for vehicle blind spots. Background technique [0002] When the vehicle is running, the driver observes the road and vehicle conditions on both sides and behind the vehicle through the rearview mirrors on both sides of the front window. Due to the insufficient field of view of the rearview mirror of the vehicle, there are always blind spots for visual observation on both sides of the vehicle window when the driver is driving, and the driver cannot observe whether there are vehicles or pedestrians in the area through the rearview mirror. Therefore, there are potential safety hazards in driving links such as vehicle lane changing and merging. [0003] For a long time, people have made various technical improvements to eliminate blind spots of vehicles, for example, double-curvature rearview mirrors, side-view camera image technology...
