Method and device for recommending planned routes

A technology for planning routes and recommending methods. It is applied to measurement devices, traffic control systems of road vehicles, road network navigators, etc. It can solve problems such as affecting driving speed, invalidation of regulatory information, and time changes, so as to avoid violations of traffic laws and regulations. The effect of detouring, reducing storage and computing space, and reducing the possibility of changes

Problems solved by technology

[0002] In the existing car navigation, the route planning function considers the factors such as road restrictions and traffic lights. The general method is to create a time zone for the user based on the current time at the beginning of the route calculation. When the time regulation is in Within this time zone, the route will avoid this road section, but the time zone obtained from this is general and the accuracy is poor, so it is easy to cause the user to drive to this road section at an unregulated time point, and the route calculation process However, it avoids driving on this section of the road, causing the user to take the wrong driving route or detour; and during the driving process of the sel

Embodiment 1

[0062] The present invention provides a calculation method and device for a planned route. Firstly, according to the location of the departure place and the destination, the relevant road and intersection information within a certain range is acquired; the speed information stored in the navigation is used to estimate and calculate the time to reach each intersection , calculate the route by obtaining the corresponding restriction information at the corresponding time, and provide an initial planned route; after the user walks according to the initial planned route, reacquire the relevant road and intersection information within the range determined by the current location and destination, Combined with the actual walking speed and real-time information at that time, recalculate the arrival time at each intersection, and compare the arrival time stored in the first calculation with the arrival time obtained by the current calculation to determine whether they belong to the same ...

Embodiment 2

[0146] This embodiment provides a method for recommending route planning, the method including:

[0147] S301 Receive a route calculation instruction and determine an initial route area;

[0148] S302 Calculate the first time to arrive at the intersection in the initial route area, and determine at least one original recommended route in combination with the restriction rules corresponding to the intersection;

[0149] S303 acquires the current location of the terminal, and determines the unpassed intersections on the original recommended route;

[0150] S304 Judging the consistency between the second time of arriving at an unpassed intersection on the original recommended route and the first time, and determining whether to calculate at least one alternative recommended route.

[0151] Further, determine the initial route area, including:

[0152] The locations of the origin and the destination are respectively determined, and the first closed area is set with the distance ...

Abstract

The invention discloses a method and device for recommending planned routes. The method includes the following steps that: a route calculation instruction is received, an initial route area is determined; first time to arrive at intersections in the initial route area is calculated, and at least one original recommendation route is determined according to restriction rules corresponding to the intersections; the current position of a terminal is obtained, intersections that the original recommendation routes do not pass are determined; and the consistency of second time to arrive at the intersections that the original recommendation routes do not pass and the first time is judged, and whether at least one alternative recommendation route is to be calculated is determined. According to themethod and device for recommending the planned routes of the invention, the planned routes are calculated effectively on the basis of the make full use of the traffic restriction information of roads,so that more accurate planned routes can be provided for users, and behaviors such as violating traffic regulations and detouring caused by navigation guidance errors can be effectively avoided.

Description

technical field [0001] The invention relates to a method and device for recommending planned routes. Background technique [0002] In the existing car navigation, the route planning function considers the factors such as road restrictions and traffic lights. The general method is to create a time zone for the user based on the current time at the beginning of the route calculation. When the time regulation is in Within this time zone, the route will avoid this road section, but the time zone obtained from this is general and the accuracy is poor, so it is easy to cause the user to drive to this road section at an unregulated time point, and the route calculation process However, it avoids driving on this section of the road, causing the user to take the wrong driving route or detour; and during the driving process of the self-vehicle, due to many factors that will affect the driving speed, it may also cause the arrival time of the self-vehicle to change, or The previous reg...
