Problems solved by technology

[0003] 1. The CAN system is relatively busy, which will increase the load of the navigation system and have a greater impact on the stability of the system
[0004] 2. The information on the active driving display screen is updated too frequently, which will cause interference to the driver; if the update frequency of the navigation guidance information is low, it will have little effect on the driver's guidance reminder

Embodiment Construction

[0022] Such as figure 1 As shown, a specific embodiment of the present invention, a method for updating and optimizing navigation guidance information of an active driving display screen, is characterized in that it includes the following steps:

[0023] S1. After the navigation has planned the route, the navigation will inform the instrument that the active driving display will display the current guidance action and the distance from the current guidance point according to the defined protocol;

[0024] S2. According to the current actual vehicle speed, the navigation system judges the distance traveled by the vehicle, and updates and displays the guidance information according to the distance;

[0025] S3. When the distance from the current parking space to the current guidance point is greater than or equal to 1000 meters, the distance from the current guidance point is updated every time the vehicle travels forward for 1000 meters;

[0026] S4. When the distance from the...

Abstract

The invention discloses an active driving display screen navigation guidance information updating optimizing method. The active driving display screen navigation guidance information updating optimizing method comprises following steps: S1, navigation route planning is carried out; S2, guidance information is updated and displayed by a navigation system; S3, when the distance from an automobile to a present guide point is larger than or equal to 1000m, the distance from the automobile to the present guide point is updated every time the automobile moves 1000m forward; S4 when the distance from the automobile to the present guide point is smaller than 1000m but larger than 100m, the distance from the automobile to the present guide point is updated every time the automobile moves 100m forward; S5, when the distance from the automobile to the present guide point is smaller than or equal to 100m, the distance to a present guide action is updated every time the automobile moves 10m forward; and S6, when the automobile is drove away from the present guide point, the action and distance of a nearest guide point are updated and displayed. The active driving display screen navigation guidance information updating optimizing method is capable of reducing automobile parts loss, prolonging automobile service life, is flexible to control, and is excellent in application effect.

Description

technical field [0001] The invention relates to the technical field of car navigation technology, in particular to a method for updating and optimizing navigation guidance information of an active driving display screen. Background technique [0002] The functions of modern car navigation all have the display and prompt of guidance information. In order to make the driver obtain guidance information more safely, the vehicle is equipped with an instrument with an active driving display, and the navigation guidance information is displayed on the active driving display. The source of the navigation guidance information displayed on the active driving display is the navigation, and the two communicate through the CAN bus. If the guidance information sent by the navigation is too frequent, it will cause two problems: [0003] 1. The CAN system is relatively busy, which will increase the load of the navigation system and have a greater impact on the stability of the system. [0...
