Description

technical field [0001] The invention relates to the technical field of assisted driving of vehicles, in particular to a system and method for assisted driving of vehicles based on road perception of unmanned aerial vehicles. Background technique [0002] With the popularization and application of vehicle assisted driving technology, the UAV assisted driving system with larger coverage and stronger situational awareness has become an important solution in the field of vehicle assisted driving. At present, the vehicle assisted driving system mainly collects road condition information around the vehicle through various sensors installed on the vehicle to assist the driver in completing the driving task of the vehicle. However, a major limitation of this method is that the sensors are often fixedly installed on the vehicle body, and the collected road condition information is limited to the surroundings of the vehicle body, so it is difficult to determine the real-time traffic c...

AI Technical Summary

Problems solved by technology

However, this method has a big limitation that the sensors are often fixedly installed on the vehicle body, and the collected road condition information is limited to the surroundings of the vehicle body, making it difficult to determine the real-time traffic conditions that are far away from the vehicle

At the same time, due to the limited viewing angle of the sensor fixed on the vehicle, it can only realize information collection within a fixed direction range. When there are obstacles or other vehicles blocking it, it is impossible to detect the road conditions in the blind spot of sight, and it is difficult to assist the driver to navigate the route. Planning and Security Alerts

[0003] On the other hand, in the existing UAV-assisted vehicle driving systems, the road condition information obtained by the UAV is rarely fused with the road condition information obtained by the vehicle itself.

[0004] Usually, the energy carried by the UAV itself is limited. How to make the UAV fly in the air for a longer time is a problem that cannot be ignored. In the past UAV-assisted vehicle path planning methods, the energy loss of the UAV was rarely considered, and Most of the existing route planning methods determine the starting point and the ending point, and search from the starting point to the ending point to determine the driving path of the target vehicle. However, when the target vehicle is driving between urban roads, the road condition information often changes rapidly and dynamically with time, so The trajectory change of the target vehicle is often caused by the change of obstacles (such as the sudden deceleration of the vehicle in front), and is not static. Therefore, the existing auxiliary vehicle driving technology lacks UAV-assisted vehicle driving process, which can ensure the quality of road condition information while A solution that can reduce the energy consumption of UAV flight as much as possible
