Safe driving warning system for vehicle and corresponding warning method

Abstract

The invention discloses a safe driving warning system for a vehicle and a corresponding warning method. The warning method includes the steps of information acquisition, information processing, safe driving warning for the vehicle and the like. Driving state information of the vehicle is acquired in real time through a driving state information acquisition module and transmitted to a master control unit in real time, and the master control unit transmits the driving state information of the vehicle to other vehicles through an information transmitting and receiving module and receives vehicle driving state information transmitted by master control units of other vehicles; according to the vehicle driving state information, time required when the vehicle reaches an impact point is predicted and analyzed, the predicted time is compared with a reference value of safe driving of the vehicle, corresponding judgment is output according to the detection and comparison result, and then an alarm can be given in time for warning. The safety driving warning system for the vehicle is the carrier of the warning method. The warning system is simple in structure and easy to implement and can provide detailed driving information of other vehicles for a driver, so that safe driving of the vehicle is guaranteed. The safe driving warning system for the vehicle and the corresponding warning method are applicable to various vehicles.

Description

technical field [0001] The invention belongs to the transportation safety technology and relates to safe running of vehicles, in particular to a warning system for safe running of vehicles and a corresponding warning method. Background technique [0002] With the increase in the number of motor vehicles, the traffic flow on urban roads and expressways has shown a significant increase trend, making driving safety more severe. Especially in the process of vehicle turning, if the front of the vehicle is blocked by large vehicles such as large trucks, the driver will not be able to clearly understand the traffic conditions ahead, and thus cannot accurately grasp the relative position and relative speed of the surrounding vehicles, resulting in continuous collisions danger. In addition, when the vehicle is overtaking at high speed, the driver may not be able to detect some vehicles approaching at high speed due to the blind spot of the rearview mirror; . In the above situatio...

AI Technical Summary

Problems solved by technology

Especially in the process of vehicle turning, if the front of the vehicle is blocked by large vehicles such as large trucks, the driver will not be able to clearly understand the traffic conditions ahead, and thus cannot accurately grasp the relative position and relative speed of the surrounding vehicles, resulting in continuous collisions danger

In addition, when the vehicle is overtaking at high speed, the driver may not be able to detect some vehicles approaching at high speed due to the blind spot of the rearview mirror;

Under the above circumstances, the vehicle in front may suddenly brake or decelerate, and the vehicle behind may cause continuous collision accidents due to unclear vision, which will bring hidden dangers to safe driving.

[0003] In order to solve the above problems, some existing vehicles are equipped with external vehicle detection systems, but these detection systems generally adopt the form of cameras installed outside the vehicle body, which can only monitor the visible vehicles around the vehicle. Blocking vehicles cannot be effectively detected, and the above-mentioned dangerous situations are still prone to occur
