Embodiment Construction

[0045] As mentioned in the background technology, in the actual driving process of the vehicle, there will be restrictions on the passage time, traffic flow, vehicle height, etc. of special vehicles. In this case, the existing topological map-based planning Global routing cannot be executed, reducing the user's experience with vehicle navigation.

[0046]In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0047] In the embodiment of the present invention, the vehicle information of the vehicle is collected by using a map including road attributes, and a global path from the starting point to the destination is planned according to the vehicle information and the road attributes. When the intelligent vehicle is driving, the generated optimal global path improves the feasibility of vehicle path plan...

Abstract

The invention discloses a vehicle path scheduling method and a vehicle path scheduling device. The vehicle path scheduling method comprises the following steps: acquiring a starting point and a destination of a vehicle, and positioning the starting point in a map, wherein the map comprises a road attribute; acquiring vehicle information of the vehicle; scheduling the global path from the startingpoint to the destination according to the vehicle information and the road attribute. According to the vehicle path scheduling method and the vehicle path scheduling device, the vehicle path scheduling enforceability is improved by the generated optimal global path when an intelligent vehicle travels.

Description

technical field [0001] The invention relates to the technical field of vehicle intelligent transportation, in particular to a vehicle path planning method and device. Background technique [0002] With the development of navigation technology, the application of navigation in the field of vehicles has become more and more extensive. The vehicle navigation system can receive the data information transmitted by GPS satellites through the built-in Global Positioning System (GPS) antenna, thereby determining the current position of the vehicle; it can also use the Inertial Navigation System (Inertial Navigation System, INS) for vehicle navigation. Inertial navigation system is an autonomous navigation system that does not rely on external information and does not radiate energy to the outside, such as radio navigation. The inertial navigation system is based on Newton's laws of mechanics. By measuring the acceleration of the vehicle in the inertial reference system, integratin...
