六轴驾驶行为分析算法

什么是驾驶行为分析

指的是分析车辆驾驶人员的驾驶习惯，比如统计急加速急减速急转弯等行为频次。

基于GSENSOR的驾驶行为分析

由于不能保证GSENSOR的安装是水平的,同时也无法保证GSENSOR的X轴一定沿着车头向前，所以通常算法是在静止时采集三轴数据与水平向前加速直行的三轴数据进行综合运算，以求解得出GSENSOR实际三轴与标准三轴的夹角，通过此夹算换算得出车头方向和左右方向的加速度值，再通过此加速度值与门限值作比较，得出急加速急减速和急转弯的判定。
Extensive testing has revealed that the different classes of vehicles react to G-forces differently. We therefore offer customized settings to guide the monitoring of aggressive driving in each vehicle class. Passenger Car is self-explanatory; Truck/Cube Van refers to the typical delivery type box trucks or other stepside vans; Heavy-Duty refers to larger box trucks and tractor trailers
