Problems solved by technology

However, many navigation systems do not take into account unexpected situations such as road restrictions, congestion, and control
When the user's driving direction is different from the calculated route, the vehicle may have deviated from the course after the vehicle-mounted terminal sends the navigation route, which consumes time and energy. Therefore, it is necessary to develop a navigation method that allows vehicles to reach their destination in time according to real-time road conditions and multiple paths

Embodiment 1

[0027] see figure 1 , a route navigation method for vehicles in this embodiment, comprising the following steps:

[0028] Step S10: The personnel in the vehicle use the vehicle-mounted terminal to send a route guidance request to the processor. After receiving the route guidance request, the processor calculates the route starting from the current real-time position of the vehicle to obtain the first navigation route. The navigation request includes the specific address of the destination, landmark keywords, and road house numbers. The processor is a vehicle-mounted real-time processor, and the vehicle-mounted real-time processor is connected with the vehicle-mounted terminal through a wireless network or bluetooth.

[0029] Step S20: When there is an intersection in the calculated first navigation route, the processor calculates the estimated time to reach the next intersection according to the average driving speed of the vehicle.

[0030] Step S30: When the estimated time...

Abstract

The invention discloses a path navigation method for a vehicle. The navigation method specifically comprises the following steps: a vehicle-mounted terminal sends a path navigation request to a processor; after the processor receives the path navigation request, path calculation is performed by taking the current real-time position of a vehicle as a start point to obtain a first navigation path; when an intersection exists on the calculated first navigation path, the processor calculates pre-estimated time to arrive at the next intersection according to the average running speed of the vehicle; and when the pre-estimated time to arrive at the next intersection is less than a preset threshold, the processor calculates multiple optimal second navigation paths by taking all divergent paths of the intersection as start points, and the processor sends the first navigation path or the second navigation paths to the vehicle-mounted terminal. The navigation method disclosed by the invention can calculate and present navigation of multiple paths in time, thereby greatly increasing the path selection probability, facilitating vehicle path selection, and enabling the vehicle to arrive at the destination in time conveniently.

Description

technical field [0001] The invention relates to the field of navigation, in particular to a route navigation method for vehicles. Background technique [0002] With the development of the automobile industry, people pay more and more attention to the user experience when using a car while owning a car. Existing on-board equipment can already provide users with many services, including music, video, pictures and other multimedia needs [0003] services, as well as real-time traffic information, destination maps and other driving navigation services. In particular, the use of vehicle navigation systems is becoming more and more popular. The voice prompts of the navigation system can guide the user to drive, especially when driving in an unfamiliar city, the navigation system can help the user to reach the destination conveniently and quickly. [0004] The prior art navigation system for vehicle-mounted devices often helps users plan their routes. Before or on the way to a de...
