Problems solved by technology

[0006] Second, when the car tilts to one side while driving, under the action of gravity, the inclination angle of the carriage is greater than that of the chassis, causing the carriage to swing too fast. When the inclination is large, the electronic gyroscope has not The vehicle has rolled over after the signal is collected or the vehicle has not been compensated
Because there are many compensations that cannot effectively compensate for large-angle inclinations, only by informing the driver of the warning signal and letting the driver slow down or stop the car can the potential safety hazard be eliminated
[0008] In addition, some domestic research and development institutions place the mechanical early warning device at the highest position of the car to collect the rollover signal, which also has limitations: because the signal it collects is not accurate, and it is prone to false alarms and false alarms
Because its working principle is a simple switch circuit, it cannot be identified by a computer to achieve a real early warning effect

Embodiment 1

[0030] figure 1 It is a schematic diagram of a specific embodiment of the automobile anti-rollover early warning device of the present invention, figure 2 Is its electrical schematic diagram.

[0031] In this example, if figure 1 As shown, the vehicle anti-rollover early warning device includes a side angle detection device 1 placed on the body part. The side angle detection device 1 consists of a weight swing device 101 , a permanent magnet 102 and a magnetic sensor 103 . In this embodiment, the permanent magnet 102 is installed at the end of the weight of the weight swing device, with S pole on the top and N pole on the bottom, and swings with the swing of the weight, and a magnetic sensitive element 103 is installed on the opposite side of the permanent magnet 102 , in this embodiment, the magnetic sensitive element 103 is installed on the opposite side of the permanent magnet 102 when the weight does not swing.

[0032] In this example, if image 3 As shown, the magne...

Embodiment 2

[0036] Because the variation of the resistance value of the magnetoresistor is only related to the magnetic flux passing through it, in embodiment 1, the direction of the side of the automobile cannot be known, and when the permanent magnet 102 is far away from the magnetoresistor 103, the change of the magnetic flux slows down, The resolution and accuracy of detection will decrease.

[0037] In this example, if Figure 4 As shown, the deflection angle detection device 1 is different from Embodiment 1. The permanent magnet 102 is installed on the top of the weight of the weight swing device, with the N pole on the top and the S pole on the bottom, and swings with the swing of the weight. The magnetic sensitive element 103 is installed on the opposite side of the magnet 102. In this embodiment, the magnetic sensitive element 103 is installed on the opposite side of the permanent magnet 102 when the weight does not swing, that is, directly above.

Abstract

The invention discloses an anti-rollover early warning device for an automobile. According to an electromagnetic induction principle, a magneto sensor is adopted for detecting the slip angle of the automobile, effectively detecting the oscillating dynamic information of an automobile carriage in real time and performing prevention and early warning on excessive oscillation of the automobile; and when the large-angle inclination abnormity of the automobile occurs, the slip angle of the automobile surpasses a preset threshold value to start an alarm, information is transmitted to a driver immediately, the driver slows down or stops the automobile, and the potential safety hazard is eliminated. The anti-rollover early warning device for the automobile has the characteristics of high instantaneity, high accuracy, low manufacturing cost and the like, overcomes the defects of a mechanical early warning device, is suitable for various types of automobiles, and is easy to popularize. By adopting the anti-rollover early warning device for the automobile, the using safety of the automobile is greatly enhanced, rollover accidents of the automobile are reduced, and the life and the property safety of the driver are effectively protected.

Description

technical field [0001] The invention belongs to the technical field of automobile safety, and more specifically relates to an anti-rollover early warning device for automobiles. Background technique [0002] With the growth of the economy and the increase of people's income, the number of automobiles has also increased significantly, and automobile traffic accidents have also continued to increase. The safe driving of automobiles has also become a topic of great concern to people. [0003] Various devices and equipment aimed at automobile safety emerge in an endless stream, such as airbags, anti-lock braking systems, reversing sensors, etc., which have played a certain role in reducing automobile traffic accident injuries. However, as the driving speed of the vehicle is getting higher and higher, the problem of vehicle lateral stability in driving safety becomes more and more prominent, and has not been effectively solved. Show according to relevant data: among all traffic ...
