Embodiment Construction
[0074] figure 1 A method flow for road surface detection in an embodiment is shown, including the following steps:
[0075] Step S110, collecting acceleration through road driving.
[0076] In this embodiment, the road surface is usually flat, but due to defects in road quality, etc., there are also raised or sunken places, for example, there may be raised places such as speed bumps and soil bumps on the road surface, and also There may be sunken places such as manhole covers and pits, so the collected acceleration can effectively reflect the changes of the road surface. The collected acceleration includes the acceleration in three directions in the three-dimensional space, that is, the acceleration in the vertical direction. During the driving process on the road surface, any acceleration corresponding to various movement changes such as shaking, falling, rising and falling are collected to obtain a series of acceleration sequences.
[0077] Step S130, determining a mixed G...
