Embodiment 1
[0095] Embodiment 1: The safety discrimination and disposal method during the driving process of the intelligent network-linked self-driving car is used for Figure 4 A highway section shown. Vehicles are driving on the carriageway, with one vehicle at the front and the rear, the overtaking lane on the left and the emergency lane on the right. After data detection and extraction, the speed of the vehicle is 90km / h, the relative speed to the vehicle in front is 30km / h, the relative distance to the vehicle in front is 100m, and the deceleration limit of the vehicle itself is 7m / s 2 ; Vehicle braking lag time is 0.3s; the current road traffic management speed is 100km / h, and the safety distance is 160m. After obtaining the above data, start the safety status of the vehicle operation.
[0096] The distance between two vehicles is 100m less than the safety distance of 160m, and the relative speed is 30km / h>0, calculate the deceleration a required for deceleration - 1 =1.46m / s ...
Embodiment 2
[0099] Embodiment 2: The safety discrimination and disposal method during the driving process of the intelligent networked automatic driving vehicle is used for Figure 5 A highway section shown. The vehicle is driving on the roadway, and there are 8 vehicles around, numbered 2 to 9. After data detection and extraction, the speed of the vehicle is 75km / h, and the maximum deceleration of the vehicle itself is 7m / s 2 , vehicle acceleration and braking lag time 0.3s. The weight of the vehicle is 1800kg, there is no one in the vehicle and no cargo. The traffic management speed of the current road is 100km / h, and the safety distance is 160m. The relevant information of the surrounding vehicles is shown in the table below. After obtaining the above data, the safety status of the vehicle operation is started, and the required data and results are summarized in the table below.
