Abstract

The invention discloses a vehicle collision detection method and system. The corresponding collision trigger threshold is obtained by matching from a database according to the car model, the installation position and the installation method of the gravity sensor; The collision trigger threshold corresponding to the installation position and different installation methods; read the acceleration value of the car and the data information of the car machine; judge whether the car has collided according to the acceleration value, the data information of the car machine and the collision trigger threshold; improve the detection of collision events Accuracy avoids the problem of misjudgment or missed judgment in the prior art as much as possible, and realizes fast and accurate vehicle collision detection.

Description

technical field [0001] The invention relates to the technical field of automobile collision detection, in particular to an automobile collision detection method and system. Background technique [0002] With the continuous development of the automobile industry, the number of vehicles is increasing, and various accidents are also increasing. The demand for collision alarms and timely preservation of evidence is stronger. Many devices currently have these functions. [0003] The existing collision alarm equipment mainly detects collisions by triggering the threshold of the gravitational acceleration sensor (G_sensor) as the judgment condition for detecting collisions. The acceleration of the G-sensor is generally composed of three vectors X, Y, and Z. X: Acceleration The left and right change axis during acceleration; Y: the front and rear change axis during acceleration; Z: the up and down change axis during acceleration. At present, many detection methods adopt the method ...
