Abstract

The invention discloses a vehicle navigation system with the high safety and a guiding method thereof. The vehicle navigation system comprises a real-time data collection unit, a data processing unit, a navigation map storage unit and an output reminding unit; the data processing unit receives real-time data collected by the real-time data collection unit, the real-time data is matched with map data provided by the navigation map storage unit after being processed, and then guiding information is output by the output reminding unit. Accordingly, the driving safety is promoted through sensor recognition results, sensors comprise a high-precision map, a binocular camera and a radar, the characteristics of all the sensors are combined, targeted screening and filtering are conducted, and after the results are integrated, the safety guiding information is output.

Description

technical field [0001] The invention relates to the technical field of car navigation, in particular to a car navigation system with high safety and a guiding method thereof. Background technique [0002] The car navigation system is installed on the vehicle to provide drivers with navigation and guidance services. It can locate in real time, retrieve destinations, route planning, screen and voice guidance, and help drivers reach their destinations accurately and quickly. [0003] Existing guidance services can only help drivers avoid detours, point to the correct turning direction at intersections, and prompt simple safety warnings at high-speed entrances and exits. There are few other auxiliary information that can improve safety and practicality. It is impossible to detect and analyze the surrounding environment in real time, combined with the current lane information and intersection information, to give reasonable guidance and prompts to avoid dangerous situations when ...
