Navigation information display method and device, storage medium and program product

Abstract

The embodiment of the invention discloses a navigation information display method and device, a storage medium and a program product. The method comprises the following steps: calculating the curvature of each road section on a ramp; determining the road section with the curvature greater than a preset curvature value as an effective road section; determining effective ramps in the ramps based on the starting point of the first effective road section and the terminal point of the last effective road section on the ramps; the method comprises the following steps: when entering an effective ramp, controlling a navigation terminal to perform full-view display of a corresponding scale on the effective ramp, the full-view display comprising displaying a route from a starting point to an end point of the effective ramp, and the corresponding scale being the maximum scale when the effective ramp is subjected to full-view display. According to the technical scheme, the overall route of the curved road section can be automatically displayed to the maximum degree for a user, the user can conveniently know the turning route on the ramp in detail, user operation is not needed, and the driving safety of the user is guaranteed.

Description

technical field [0001] The embodiments of the present disclosure relate to the technical field of navigation, and in particular, to a method, device, storage medium, and program product for displaying navigation information. Background technique [0002] In the T-type (Y-type) interchange, the main road that intersects is usually defined as the main line, the intersecting secondary road is defined as the lead, and the line connecting the lead and the main line is called the ramp. Usually, the part connecting the main line and the lead at both ends of the ramp is a curved section, and the middle part of the ramp is mostly a straight section. At present, when displaying the navigation information of the ramp, the navigation terminal will only display the road sections on the ramp according to a fixed scale. However, when the user drives the vehicle on the ramp, he will pay more attention to the bending directions of both ends of the ramp for subsequent driving actions. If the...

Problems solved by technology

At present, when the navigation terminal displays the navigation information of the ramp, it will only display the road section on the ramp according to a fixed scale. However, when the user drives the vehicle on the ramp, he will pay more attention to the bending direction at both ends of the ramp for subsequent driving actions. If the subsequent turning direction cannot be seen in the displayed road section, the user needs to drag the navigation map to view the detailed map information at both ends of the ramp. This method is complicated to operate, easily distracts the user's driving attention, and affects driving safety.
