Embodiment Construction
[0029] The application scenario of this embodiment is: KIAK5 and HTCDesireG7, HondaAccord and HuaweiHonor3C, VolvoS60L and ZTEU809, MazdaAtenza and HTCEVO3D, AudiA4L and SAMSUNGN Nexus4 are selected as experimental vehicles and mobile phones, wherein: each vehicle is equipped with a driving recorder, so that the shooting content as the calibrated real data. The collected data comes from the natural driving of 5 drivers over a period of 5 months.
[0030] In this embodiment, a smart terminal with a built-in sensor (acceleration sensor and GPS sensor) is used for data collection, the jitter noise in the data is removed through a low-pass filter, and then the coordinate system of the mobile phone is aligned with the coordinate system of the vehicle, and according to the data detected by the smart terminal Acceleration information judges the current lane-changing behavior of the vehicle and the number of lanes crossed when changing lanes, such as figure 1 shown.
[0031] The sin...
