Embodiment
[0059] Such as figure 2 Shown is a schematic diagram of the overtaking situation of vehicles in automatic mode on the two-way 2-lane inner road that allows borrowing. 2201 is the overtaking behavior of the inner road on the dedicated 2-lane road. 2202 is the vehicle in automatic driving mode. The specific overtaking steps are as follows:
[0060] 1) With the support of vehicle-road coordination technology, obtain the position and speed information of associated vehicles within the range in real time and make real-time predictions;
[0061] 2) Control the speed of the vehicle until the safe lane change condition is reached, and then start to drive on the inner road;
[0062] 3) Adjust the speed of the vehicle to achieve overtaking on the inner road, and after reaching the safe lane change distance, the vehicle returns to the original driving lane to complete the overtaking process.
[0063] Such as image 3 Shown is a schematic diagram of a vehicle in automatic mode overtaki...

The invention discloses an overtaking method of automatic driving in an overtaking lane. The overtaking method comprises the steps that with the support of a vehicle-road cooperation technology, an automatic driving vehicle obtains the position and speed information of related vehicles within a range in real time and performs real-time prediction, if an extended overtaking specific lane exists infront of the automatic driving vehicle, the vehicle speed is controlled, a safe distance is maintained, when the automatic driving vehicle drives to the extended overtaking specific lane, the vehicleis controlled to drive into, the vehicle speed is adjusted to ensure that the vehicle achieves overtaking in the extended overtaking specific lane, and when the safe distance at which a lane is capable of being changed is reached, the vehicle returns to an original driving lane, and the overtaking process is completed. According to the overtaking method of automatic driving in the overtaking lane,overtaking of the automatic driving vehicle in different driving scenarios is achieved under the vehicle-road cooperative environment.
Description
technical field [0001] The invention relates to the technical field of automatic driving, in particular to an overtaking method for automatic driving overtaking lanes in different lane scenarios. Background technique [0002] With the application of more and more autonomous driving technologies, more and more unmanned autonomous vehicles will inevitably appear on the road in the future. However, based on the current statistical data, the accident rate of self-driving vehicles is still significantly higher than that of human driving, which leads to the fact that the actual driving ability of self-driving technology cannot be fully trusted by people. In other words, safety is one of the core issues that autonomous driving needs to solve, and it is also the main obstacle to the rapid development of its related technologies. [0003] In the field of autonomous driving safety, in addition to accurately calculating and maintaining the distance between front and rear vehicles, a m...
