Embodiment Construction
[0101] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0102] One of the core concepts of the embodiments of the present invention is that adjusting one or more sets of acquired triaxial accelerations can eliminate the influence of gravity on the triaxial accelerations, and eliminate the influence of road bumps on the triaxial accelerations in the direction of gravity. According to the actual acceleration, one or more sets of direction vectors and one or more sets of turning vectors are calculated, and it is judged whether the ratio of the direction vectors to the turning vectors exceeds the preset threshold, and it can be determined whether the vehicle is Whether it is in a forward state or a turning state, one or more sets of actual acceleration direction vectors are accumulated to f...
