A kind of vehicle collision alarm detection procedure of the present invention is mainly to vehicle by using the collision detection algorithm of innovation
No crash is detected；Usual vehicle is in normal driving process, the either acceleration of acceleration or deceleration vehicle
Value is general all in a fixed scope, certain different types of vehicle as quality is different and scope is different, but together
Whether the vehicle of one type is nearly all in a fixed scope, therefore, first by judging the acceleration magnitude of vehicle in fixation
In the range of, so as to judge vehicle whether in normally travel；But vehicle can also occur once in a while after the braking that emergency occurs
Safety continues situation about travelling again, therefore whether the present invention program continues to examine in the acceleration of detection vehicle after normal variation, again
Whether the velocity amplitude of measuring car drastically reduces, and whether exceedes a certain setting value, therefore energy in a period of time after reduction
It is enough to ensure further to detect that vehicle produces the situation of hard brake stop because crashing, reduce rate of false alarm.
The first heretofore described preset time T1, the second preset time T 2, the 3rd preset time T3, predetermined acceleration
Value K, pre-set velocity value V are the value ranges for being occurred according to multiple accident experience and being set, and different vehicles can basis
Situation is finely adjusted.

Preset time T1, the second preset time T2, the 3rd preset time T3, predetermined acceleration value K, pre-set velocity value V；In vehicle traveling
During, the real time acceleration value M received is compared by described control unit with acceleration preset value K, if pre- first
If time T1The real time acceleration value M of interior vehicle is above predetermined acceleration value K, then control unit is determined as occurring doubtful touch
Hit, and will continue real-time speed value N being compared with speed preset value V, if in the second preset time T2Interior vehicle it is real-time
Velocity amplitude N is reduced to below pre-set velocity value V, and in ensuing 3rd preset time T3Interior, vehicle real-time speed value N is
No more than pre-set velocity value V, then control unit judgement collides；Collision information is sent to communication unit simultaneously.
Real time acceleration and velocity amplitude and system acceleration magnitude set in advance and speed that said system passes through collection vehicle
Angle value is compared within the default time, determines whether occur vehicle collision accident, can be in time by car if occurring accident
Present position information, the acceleration magnitude and velocity amplitude for colliding vehicle in front are sent to third party Surveillance center.Wherein third party supervises
Control center can be the third parties such as governmental transportation body, 4S shops or service center, be collided information when receiving vehicle
Afterwards, can be according to the acceleration magnitude of vehicle, the grade of speed preliminary judgement accident, and then rescue method is arranged, realize rescue
Promptness and reasonability.Wherein communication unit can be real with third party Surveillance center using any communication mode of the prior art
Existing data communication, for example with modes such as GPRS communications, Internet.
In the present invention, control unit can realize that acceleration collecting unit uses acceleration transducer using dsp chip
The collection to vehicle real time acceleration value is realized, speed acquisition unit is realized to the real-time speed value of vehicle using GPS chip
Collection, at the same GPS chip can also collection vehicle positional information, acceleration transducer, GPS chip will collect vehicle acceleration
Value and velocity amplitude are uploaded to control unit in real time, are judged by control unit.
In order to skilled artisans appreciate that and implement technical solution of the present invention, the present patent application scheme will be combined
Instantiation is illustrated.
Setting scheme background is that vehicle should possess control unit, acceleration and speed acquisition device, can use microprocessor
Device, acceleration transducer, GPS chip are realized；Setting vehicle has set collision parameter, the first preset time T before traveling1If
It is set to 0.2s, the second preset time T2It is set as 10s, the 3rd preset time T3It is set as that 90s, predetermined acceleration value K are set as
3000mg, pre-set velocity value V is set as 3 km/h；After vehicle enters normally travel, acceleration transducer, GPS chip collection
The real time acceleration value and velocity amplitude of vehicle, microprocessor realize monitoring function；When monitoring vehicle within 0.2s time, plus
Velocity amplitude is above 3000mg, then shows that vehicle is in improper acceleration mode, in fact it could happen that doubtful collision；Microprocessor after
Continuous monitoring, if speed drops to 3 below km/h within 10s time, then it represents that confirm that vehicle occurs in that doubtful collision accident；
Microprocessor continues to monitor, if within 90s time, car speed is all in 3 below km/h, then it represents that occur vehicle collision, together
When microprocessor the vehicle maximum acceleration value collected, maximum speed value, vehicle position information can be uploaded to Surveillance center,
Rescue method can be arranged in time after Surveillance center receives alarm signal, and accurately finds accident spot.
One of ordinary skill in the art will be appreciated that embodiment described here is to aid in reader and understands this hair
Bright principle, it should be understood that protection scope of the present invention is not limited to such especially statement and embodiment.This area
Those of ordinary skill can make according to these technical inspirations disclosed by the invention various does not depart from the other each of essence of the invention
Plant specific deformation and combine, these deformations and combination are still within the scope of the present invention.
