Embodiment Construction

[0040] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment:

[0041] The warning method that the present invention proposes to prevent automobile rear-end collision specifically adopts following technical scheme, see figure 1 The flowchart shown includes the following steps:

[0042] ⑩System startup;

[0043] System self-test;

[0044] Whether the system fails, if there is a failure, turn on the manual control switch, manually select the corresponding alarm voice file according to the failure, and transmit it to the voice circuit; if there is no failure, continue to the next step;

[0045] Each sensor collects the vehicle status signal according to the set order;

[0046] Convert the state information into digital signal, input it to the central processing unit, and compare it with the set threshold;

[0047] Judging whether the preset threshold is exceeded, if the threshold is not exceeded, ret...

Abstract

The invention relates to the technical field of vehicle safety, in particular to a warning method and system for avoiding vehicle rear-end collision. The method provided by the invention comprises thesteps of collecting vehicle state information according to sensor signals and converting state information into digital signals to be input into a central processing unit, judging whether the digitalsignal value exceeds a preset threshold value; if not, returning to step 2, and if yes, performing the next step; selecting a corresponding warning signal from a voice file, outputting to a voice circuit and giving out the warning signal. The system provided by the invention is composed of an acceleration transducer, a speed sensor, other sensors, a voice file, a voice module, a power amplifier circuit, a loudspeaker, a central processing unit and the like. When faults, such as tire burst, collision, roll over, secondary rear-end collision and the like, occur to a vehicle, the invention can notice a rear vehicle of the state of the vehicle with voice, can effectively prevent rear-end collision from occuring in severe weather and ensures the life safety of a driver.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to an alarm method and system for preventing automobile rear-end collision. Background technique [0002] The current method to prevent rear-end collisions is usually to monitor the distance between vehicles in front to prevent your own vehicle from colliding with the vehicle in front, but this method cannot solve the secondary damage to the vehicle, especially in foggy weather conditions. Vehicles only have minor faults, and these minor faults may be fatal. Due to the insufficient perspective of the fog, when these faults break down, they will cause fatal rear-end collisions, which will cause greater casualties and property damage. [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides an alarm method and system for preventing rear-end collisions of vehicles after an accident occurs, so as to prevent other vehicles from posing...
