Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.
Embodiment one
Please refer to Fig. 1,3-6, in the embodiment of the present invention, a method of judging vehicle collision and bring to a halt, including step S1-S5, specific as follows:
In step sl, initial X, Y, Z tri- is determined according to the data in the 3-axis acceleration sensor of vehicle stabilization state The acceleration component values of axis direction, wherein the component of acceleration of tri- axis direction of X, Y, Z is respectively ax, ay, az;
The installation site of above-mentioned 3-axis acceleration sensor can be placed arbitrarily, not emphasize the judgement of its corresponding direction, preferably It is mountable on cigarette lighter socket.
In step s 2, the acceleration component values according to 3-axis acceleration sensor in tri- axis direction of X, Y, Z determine synthesis Acceleration, resultant acceleration is a herein, in conjunction with ax, ay, the az determined in step S1, using calculation formula
A=(ax2+ay2+az2)0.5
Obtain resultant acceleration a;
In step s3, acceleration when bringing to a halt, suddenly accelerating and collide is determined according to resultant acceleration, and then is determined Fainting for resultant acceleration is worth range when vehicle is caused danger;
It can be obtained according to the calculation formula of a in step S2, static or when driving at a constant speed, the value of resultant acceleration is vertically downward Acceleration of gravity, in the presence of having the acceleration or deceleration of any direction, the value of resultant acceleration can change, public according to calculating This value of formula can embody the situation of change of vehicle acceleration, and vehicle brings to a halt acceleration in 0.9G or so, anxious acceleration acceleration In 0.5G or so, and the acceleration of product collision is in 10G or more, therefore the acceleration of vehicle collision and normal operating have significantly The foundation that detection threshold is caused danger as vehicle can be arranged, because normal driving can not produce in difference between 1.5-10G Raw such high acceleration;
The judgement that automobile emergency brake is carried out using resultant acceleration, due to not emphasizing the installation appearance of 3-axis acceleration sensor State, therefore the value of resultant acceleration can not embody the direction of acceleration only embodies the value of resultant acceleration, both horizontally and vertically plus Speed be it is indistinguishable, have 0.9G or so acceleration due to bringing to a halt in the horizontal direction, vehicle is by deceleration strip or crossing a pit When can also generate 0.9G or acceleration larger, finally can all be embodied in close accelerate value in, cause the erroneous judgement brought to a halt, It is therefore proposed that step S4, as follows:
In step s 4, the maximum axis of acceleration value in three axis is taken to seek conjunction under stationary state as reference axis and add Speed, as reference data, then reads at any time and closes with reference to axle acceleration and with reference to the ratio of axle acceleration and resultant acceleration Acceleration, with reference to axle acceleration, both calculate ratio, eliminate and judged by accident caused by normal acceleration variation, determine final synthesis plus Fainting for speed is worth range.
Using the method in step S4, when generating the acceleration of vertical direction, with reference to axle acceleration and resultant acceleration Ratio is basically unchanged, and when generating the acceleration with certain level component, the ratio of the two can change, in different sensings Device posture, ratio variation is non-constant, but the variable quantity of ratio is capable of the variation of a degree of reaction acceleration level component Amount, therefore certain threshold value is reached by resultant acceleration variation, surpass simultaneously with reference to axle acceleration and the ratio of resultant acceleration Certain threshold value is crossed to judge bringing to a halt for vehicle, can effectively avoid vehicle by deceleration strip and crosses a pit the anxious acceleration mistake of generation Sentence.
In step s 5, according to the acceleration value that acquires in real time and the value of initially fainting determined, determine whether to collide or Emergency brake.
In one embodiment of the application, when determining whether to occur vehicle collision, set according to the acquisition of default frequency acquisition is vehicle-mounted Acceleration component values in standby each reference axis of coordinate system, it is later determined that resultant acceleration;Judging resultant acceleration collected is The threshold value of the no resultant acceleration for being greater than setting, if so, it is judged to occurring vehicle collision, thus, using the judgement of the application The mode of vehicle collision can be realized no matter mobile unit is arbitrarily installed, and can accurately judge that vehicle actually occurred touches It hits.
