Problems solved by technology

[0002] The navigation system plays a key role in the driving process and can plan the path from the starting position to the target position. However, traditional path planning often considers factors such as high speed, congestion level, and driving time, but ignores the turning radius of the vehicle. Does it match the radius of the curve in the route? Therefore, after driving on the route planned by the navigation, a curve is found, and the vehicle cannot turn smoothly, resulting in a dilemma

Embodiment 1

[0026] Such as figure 1 As shown, embodiment 1 provides a kind of navigation system, comprises: processor module, the Beidou navigation positioning module that is connected with this processor module, data storage module; Described data storage module is stored with map data, vehicle type turning radius data; The processor module is adapted to plan a navigation route according to the current location of the vehicle and the input target location, as well as the turning radius data of the current vehicle.

[0027] The processor module, for example, adopts an embedded chip, and the processor module is also connected with a touch screen, so as to perform corresponding input operation and display.

[0028] Specifically, the vehicle type turning radius data includes but not limited to the length, width, wheelbase, vehicle turning radius and other data of various types of vehicles; Find the turning radius data that matches the vehicle type, and use the turning radius data as an impo...

Embodiment 2

[0042] On the basis of embodiment 1, present embodiment 2 provides a kind of working method of navigation system, and described navigation system comprises: processor module, the Beidou navigation positioning module that links to each other with this processor module, data storage module; The storage module stores map data and vehicle type turning radius data; the working method includes: the processor module is adapted to plan a navigation route according to the current location of the vehicle and the input target location, and combined with the turning radius data of the current vehicle. .

[0043] The processor module is adapted to pre-calculate several preliminary planning navigation paths between the vehicle's current location and the input target location; and search for corresponding curved road sections in each preliminary planning navigation path, and turn The radius data filters each curved road section, that is, obtains the planned navigation path corresponding to t...

Embodiment 3

[0050] Such as Figure 3a , Figure 3b with Figure 3c As shown, on Embodiment 1, Embodiment 3 provides a vehicle.

[0051] The front of the vehicle is provided with multiple rows of front wheels, and each row of front wheels corresponds to an independent steering device and a driving device, and each steering device and driving device are connected to a vehicle-mounted electronic ECU system, and the vehicle-mounted electronic ECU system is connected to the vehicle-mounted electronic ECU system. connected to the navigation system.

[0052] The vehicle-mounted electronic ECU system is connected with the vehicle-mounted panoramic camera device, and photographs the turning posture of the vehicle, specifically detects whether the vehicle is in the current lane, and feeds back the detection result to the vehicle-mounted electronic ECU system.

[0053] When the vehicle enters a curve, it first uses the first row of front wheels as the main steering wheel to make a turning action,...

Abstract

The invention relates to a navigation system based on a Beidou, a work method of the navigation system and a vehicle equipped with the navigation system. The navigation system comprises a processor module, and a Beidou navigation positioning module and a data storage module which are connected with the processor module, wherein the data storage module is stored with map data and vehicle model turning radius data, and the processor module is suitable for planning navigation paths according to the present position of the vehicle and an inputted target place in combination with the vehicle model turning radius data of the present vehicle. The navigation system is advantaged in that a minimum turning radius r in matching with a model of the vehicle can be searched according to the vehicle model turning radius data, corresponding winding road segments can be searched from the navigation paths preliminarily planned based on the map, the winding road segments can be screened according to the turning radius data corresponding to the vehicle model, a planned navigation path corresponding to the winding road segments suitable for the vehicle model can be acquired, and the vehicle is guaranteed to arrive the destination smoothly.

Description

technical field [0001] The invention relates to the field of navigation, in particular to a Beidou-based navigation system, a working method and a vehicle installed with the navigation system. Background technique [0002] The navigation system plays a key role in the driving process and can plan the path from the starting position to the target position. However, traditional path planning often considers factors such as high speed, congestion level, and driving time, but ignores the turning radius of the vehicle. Whether it matches the radius of the curve in the path, so after driving the route planned by the navigation, it will find that there is a curve, and the vehicle cannot turn smoothly, resulting in a dilemma. [0003] Therefore, how to avoid the above technical problems and improve the intelligence of navigation for path planning is a technical problem in this field. Contents of the invention [0004] The purpose of the present invention is to provide a navigatio...
