Problems solved by technology
[0003] The collision detection technology based on the acceleration sensor is more economical, but when the vehicle is driving on a complex road condition, this detection technology may cause false alarms or no reporting
For example, assuming that there are sewer manhole covers or speed bumps in the road conditions, the vehicle will vibrate greatly when passing these places, and some car owners will have a greater braking force when passing these places, which makes the acceleration sensor installed on the car generate more vibration. A large difference can easily generate false positives
[0004] At the same time, because different types of vehicles have different body parameters, which lead to different collision preset values, it is very difficult to use and maintain collision detection technology on many types of vehicles

Embodiment 1
[0022] Such as figure 1 Shown, a kind of vehicle collision detection system based on vehicle-mounted OBD interface, comprises acceleration sensor 3, vehicle-mounted OBD interface 2, GPS module 4, processor 1, GPRS module 5 and platform server 6, wherein acceleration sensor 3, vehicle-mounted OBD interface 2 , the GPS module 4, and the GPRS module 5 are connected to the processor 1, and the GPRS module 5 and the platform server 6 establish a data connection.
[0023] In the above scheme, the processor 1 collects vehicle features through the vehicle-mounted OBD interface 2, and then uploads the collected vehicle features to the platform server 6 through the GPRS module 5, and the platform server 6 queries the vehicle features to obtain a collision prediction that matches the vehicle features. Set the value, and then send the collision preset value to the processor 1 through the GPRS module 5. Since the platform server 6 is used to realize dynamic management of collision preset ...

Description
technical field [0001] The present invention relates to the field of vehicle collision detection, more specifically, to a vehicle collision detection system and method based on a vehicle-mounted OBD interface. Background technique [0002] The collision detection technology commonly used in the market is mainly realized by the acceleration sensor. This technology reads the values of the three axes of the acceleration sensor X, Y, and Z in a polling manner, and calculates the maximum and minimum values of each axis. The difference, and then calculate the vector of the three axes. By comparing this vector value with a preset value, if the vector value is greater than the preset value, it is considered that a collision has occurred. [0003] The collision detection technology based on the acceleration sensor is relatively economical, but when the vehicle is driving on a complex road condition, this detection technology may cause false alarms or no reporting. For example, ...
