Embodiment Construction

[0054] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0055] The prior art path planning algorithm does not consider the processing of intersections, and lacks the combination of the traffic light switching cycle of each intersection, the waiting time to pass the intersection, the driving speed of the owner, and the traffic flow to comprehensively calculate the planned path and the time to reach the destination. There is no real-time reminder to the owner or a navigation method to remind the vehicle to drive at the optimal speed to avoid waiting or reduce the waiting time to pass through the intersection with signal lights. And the current unmanned driving technology is becoming more and more mature, but there is no relevant content for the design method of vehicle speed adjustment based on the navigation path of traffic lights.

[0056] Such as figure 1 As shown, the present invention provides a method f...

Abstract

The invention discloses a method, an apparatus and a system of route planning based on autonomous driving. The method comprises the following steps: S1: vehicle parameter information is obtained; S2: navigation road information between a starting point and a destination is obtained, and the navigation road information comprises a navigation path, traffic light signals, and road condition information; S3: current driving state of a vehicle is obtained, and the current driving state of the vehicle comprises current positional information of the vehicle and driving speed of the vehicle; S4: a floating set of vehicle speed is obtained according to the current driving state and navigation road information of the vehicle; S5: according each speed of the floating set of vehicle speed, the driving time required for a whole journey is obtained, and the speed corresponding to the shortest driving time is used as an optimized vehicle speed; S6: whether driving speed of the vehicle and the optimized vehicle speed are adapted is judged, if not, the vehicle speed is adjusted to the optimized vehicle speed. The method is used for fine adjustment of the vehicle speed, in order to avoid long waiting time for traffic lights, and realize the purposes of optimization of driving experience and green low carbon transportation.

Description

technical field [0001] The invention belongs to the technical field of unmanned driving, and in particular relates to a method, device and system for path planning based on unmanned driving. Background technique [0002] With the continuous development and in-depth research of unmanned driving technology, people travel by car, and the comprehensive demand for using unmanned driving technology to improve the travel experience of vehicles has gradually become possible; vehicles will inevitably encounter intersections with signal lights during driving , the signal light transition waiting time when turning left, turning right, and going straight at the intersection. How to reduce carbon emissions, reduce energy consumption, and achieve energy saving and emission reduction by avoiding frequent braking, acceleration and long-term parking has also become an important technical link that we need to consider. In the prior art, there is no vehicle navigation and control method that ...
