Example Embodiment
[0020] Example one
[0021] This embodiment provides a method for acquiring vehicle acceleration data. The execution subject is a device for acquiring vehicle acceleration data. The device can be installed in a car or separately, for example, in a server or a mobile terminal, which can be set according to actual needs. set up. Such as figure 1 As shown, it is a schematic flowchart of a method for acquiring vehicle acceleration data according to this embodiment. The method for obtaining vehicle acceleration includes:
[0022] Step 101: Acquire first detection data of the three-axis accelerometer when the car is stationary, and second detection data corresponding to the three-axis accelerometer when the vehicle is accelerating in a straight line.
[0023] Among them, the three-axis accelerometer is a tool used to measure the acceleration of three axes in three-dimensional space.
[0024] There are many ways to judge that the car is stationary. For example, when the three-axis accelero...
Example Embodiment
[0038] Example two
[0039] This embodiment further exemplifies the method of obtaining vehicle acceleration data in the first embodiment.
[0040] First, obtain multiple sets of first sampling data of the three-axis accelerometer when the continuous speed of the car is 0. The first sampling data includes: first X-axis sampling data, first Y-axis sampling data, and first Z-axis sampling data, and Acquire first detection data according to multiple first X-axis sampling data, multiple first Y-axis sampling data, and multiple Z-axis sampling data. The first detection data includes: X-axis target data, Y-axis target data, and Z-axis target data.
[0041] Specifically, after receiving a user-triggered instruction to acquire vehicle acceleration data, the step of acquiring multiple sets of first sampling data of the three-axis accelerometer when the speed of the vehicle is 0 can be executed, that is, collecting data on each axis of the three-axis accelerometer Multiple sets of sampled da...
Example Embodiment
[0085] Example three
[0086] This embodiment provides a device for acquiring automobile acceleration data, which is used to implement the method for automobile acceleration data of the first embodiment. The device can be installed in a car or separately, for example, in a server or a mobile terminal. Set according to actual needs. Such as Figure 4 Shown is a schematic diagram of the structure of the device according to this embodiment. The device includes a first acquisition module 401, a second acquisition module 402, and a correction module 403.
[0087] Among them, the first acquisition module 401 is used to acquire the first detection data of the three-axis accelerometer when the car is stationary, and the second detection data corresponding to the three-axis accelerometer when the car is accelerating in a straight line; Data and the second detection data to obtain a correction matrix, which is used to correct the coordinate system direction of the three-axis accelerometer...
