Embodiment Construction
[0048] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.
[0049] see Figure 1-2 , a driving behavior scoring method based on BP neural network, comprising the following steps:
[0050] (1) Collect driving behavior data and determine the driving behavior index system; when using neural networks to evaluate driving behavior, it is necessary to first determine the main characteristics that can correctly reflect the driver’s driving behavior. The driving behavior includes: lane departure, front vehicle collision, Keep distance between vehicles, rapid acceleration, rapid deceleration, sharp turn, speeding;
[0051] First, the on-board ADAS system is used to collect data. The driving behavior data is collected from the road condition information collected by the on-board system ADAS camera, the number of lane departures calculated from the road condition information, the number of collisions with front vehicl...
