Problems solved by technology

[0005] Problem 1. The real-time performance is not enough. The real-time road conditions are often updated once every 1-2 hours, and it is impossible to respond to road traffic conditions in time.
[0006] Problem 2. The road condition information is not accurate enough. Although some intersections are partially congested, there may still be room for passage.

Embodiment 1

[0038] figure 1 A functional block diagram of the navigation system of the present invention is shown.

[0039] Such as figure 1 As shown, the navigation system of the present invention includes:

[0040] The monitoring device is located at each intersection and is used to capture passing video and / or images of traffic lights and / or vehicles at the intersection, and transmit the passing video and / or images through the wireless sending module.

[0041] Vehicle-mounted navigation device, planning travel route in advance, when the vehicle that is equipped with this vehicle-mounted navigation device is about to travel to the nth crossing of the planned travel route (for example: 30-150 meters away from this n-th crossing, preferably 60 or 50 meters) , receive the passing video and / or image of the n+1th intersection in the travel route for the driver to view, and then the driver judges whether to bypass the n+1th intersection according to the road conditions ahead .

[0042] Th...

Embodiment 2

[0046] On the basis of Embodiment 1, the present invention also provides a vehicle with a navigation system.

[0047] The vehicle is an electric vehicle; the vehicle is equipped with a brake electric energy recovery subsystem, and the brake electric energy recovery subsystem is connected with the vehicle navigation device, and the vehicle navigation device is also suitable for replanning the travel route. , to calculate the passing speed of the replanned route to obtain the remaining mileage of the battery in the braking electric energy recovery subsystem.

[0048] figure 2 A schematic structural diagram of the braking electric energy recovery subsystem of the present invention is shown.

[0049] 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 ...

Embodiment approach

[0062] 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.

[0063] The one-way 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 opened; and the charging effic...

Abstract

The invention discloses a navigation system, a vehicle with the navigation system and a work method thereof. The navigation system includes monitoring systems, which are arranged at crossings and are used for photographing traffic signal lights and passing videos and / or images of vehicles at the crossings, and then send the passing videos and / or images through a wireless sending module; and a vehicle-mounted navigation apparatus, which specifies a travelling route in advance, so that when the vehicle is arriving at the n crossing in the specified travelling route, the system receives the passing videos and / or images at the n+1 crossing, so that a driver can read the information. The navigation system and the work method are suitable for specifying a route according to direct determination on passing capability of the road. The navigation system has good real-time performance and displays the traffic situation more directly.

Description

technical field [0001] The invention relates to the field of navigation, in particular to a route optimization navigation system, a working method and a vehicle using the navigation system. Background technique [0002] With the development of cities, vehicles have also become an indispensable means of transportation; however, due to the substantial increase in the number of cars, road traffic pressure has also increased. [0003] Therefore, when people travel, they often plan traffic routes in advance and choose the nearest route; however, the nearest route may be congested, so the nearest route is not necessarily the optimal route for traffic efficiency. [0004] In order to solve the above problems, Baidu and other companies have also added road condition information to Baidu Maps for travel reference. However, since the above road condition information is uploaded to the service center for each intersection and road intersection, and then displayed on the map, there are ...
