Embodiment Construction
[0066] The present invention will be further described below in conjunction with specific examples.
[0067] Such as figure 1 As shown, the intelligent vehicle lane change early warning method based on instantaneous risk identification provided by this embodiment includes the following steps:
[0068] 1) Obtain basic data, including vehicle motion data, vehicle relative position information, vehicle geometric parameters, road geometric conditions and road surface friction coefficient, etc.
[0069] The vehicle motion data includes the speed and acceleration of the target vehicle and surrounding vehicles, real-time vehicle motion data can be obtained through the target vehicle sensor or roadside monitoring equipment; The distance between vehicles can be obtained from the sensor of the target vehicle or the vehicle-road collaboration platform; the vehicle geometric parameters include vehicle length and vehicle width, which can be obtained by reading the body electronic tag info...
