Problems solved by technology

[0002] In the actual navigation process of the navigator, due to the untimely update of the map and the low accuracy of the navigation signal, the vehicle travels to a complex intersection (referring to a roundabout with multiple intersections, a cross-shaped fork, a rice-shaped intersection, and an urban elevated road). When going up the crossing, etc.), the instructions of the navigator or the navigation instruction image often lag behind, or even make mistakes, or the navigation image is difficult to accurately match the actual road conditions, which easily causes the driver to drive into the wrong driving route

Embodiment 1

[0034] figure 1 A functional block diagram of the real scene navigation system of the present invention is shown.

[0035] Such as figure 1 As shown, the real-scene navigation system of the present invention includes: a navigation device and a camera; the navigation device includes: a gyroscope for obtaining the attitude of the vehicle, a GPS module for locating the position of the vehicle on a map, a display module, and a gyroscope A processor module connected to the GPS module; when the vehicle is traveling on a preset navigation route, the camera is adapted to follow the vehicle to take real-time pictures of roadside street scenes corresponding to the current vehicle attitude; the processor module is adapted to The vehicle driving direction matching the navigation path is marked on the roadside street view through the display module.

[0036] Wherein, the roadside street scene specifically refers to fixed scenes such as roadside buildings, billboards, trees, etc., excludi...

Embodiment 2

[0042] On the basis of Embodiment 1, the present invention also provides a vehicle with a real scene navigation system.

[0043] The vehicle is an electric vehicle; the vehicle is equipped with a braking electric energy recovery subsystem, and the braking electric energy recovery subsystem is connected to a navigation device, and the navigation device is also suitable for calculating The passing speed of the replanned route is obtained to obtain the remaining mileage of the battery in the braking electric energy recovery subsystem.

[0044] figure 2 A schematic structural diagram of the braking electric energy recovery subsystem of the present invention is shown.

[0045] Such as figure 2 As shown, the brake electric energy recovery subsystem includes a hydraulic brake mechanism 2 and a brake coordinating assembly 4 that cooperates with the hydraulic brake mechanism 2; when braking, the brake coordinating assembly 4 is suitable for generating The force acting opposite to ...

Embodiment approach

[0058] Specific implementation manner: the charging circuit includes a diode VD; the positive pole of the battery E is connected to one end of the electromagnetic coil 46, the other end of the battery coil is connected to the cathode of the diode VD, and the anode of the diode VD is connected to the boost voltage The output end of the module is connected, the input end of the boost module is connected to one end of the wheel drive motor M, the negative pole of the battery E is connected to the other end of the wheel drive motor M; the auxiliary switch is a normally closed switch, and the normally closed Both ends of the switch are respectively connected to the input end of the boost module and the positive pole of the storage battery E.

[0059] The unidirectional characteristic of the diode VD can effectively prevent the battery E from continuing to discharge the wheel drive motor M through the electromagnetic coil 46 after the normally closed switch is turned on; and the char...

Abstract

The present invention discloses a working method of a real scene navigation system. The navigation system comprises a navigation device and an imaging device. The working method comprises that when a vehicle drives according to a preset navigation path, the imaging device follows the vehicle and real-timely shoots the real-time image around the current vehicle; if a complex intersection exists in front of the vehicle, a processor module matches the real-time image and the street scene image of corresponding position and pre-stored in a data memory, combines the preset navigation path, and determines the position, the road and the right driving direction of the current vehicle; and a display module is controlled to display the corresponding navigation images, wherein the real-time image in front of the current vehicle, and the vehicle driving direction matched with the navigation path and labeled by the arrow are contained in the navigation image.

Description

technical field [0001] The invention relates to the field of navigation, in particular to a working method of a real-scene navigation system. Background technique [0002] In the actual navigation process of the navigator, due to the untimely update of the map and the low accuracy of the navigation signal, the vehicle travels to a complex intersection (referring to a roundabout with multiple intersections, a cross-shaped fork, a rice-shaped intersection, and an urban elevated road). When going up the crossing, etc.), the command or navigation instruction image of the navigator often lags behind, or even makes mistakes, or the navigation image is difficult to accurately match the actual road conditions, which easily causes the driver to drive into the wrong driving route. How to avoid the above-mentioned technical problems is a technical problem in the navigation field. Contents of the invention [0003] The purpose of the present invention is to provide a working method o...
