What cars are suitable for car navigation universal machines?

The kind of external one, which can be used in all cars.

The universal meaning must be usable.

For an external navigator, just give it a 12V power supply.

It is generally attached to a cigarette lighter.

According to the manufacturer and production process, the target of the car is also different, in general, it will be for the same brand, the same platform or the same model of a type of car. There is also no need to inlay, external navigation, just plug in the power supply.

Car navigation is carried out by using on-board GPS (Global Positioning System) with electronic maps, which can easily and accurately tell the driver the shortest or fastest path to the destination, and is a good helper for the driver. The general car navigation functions have *****, radio reception, Bluetooth hands-free, touch screen, optional functions, intelligent trajectory reversing, tire pressure detection function, virtual six discs, background control and other functions.

Found a very strange place, obviously the car comes with a navigation system, but many drivers will use their mobile phones to check the navigation, is it because the car's built-in navigation system is not easy to use?

The car's own navigation system is fixed in one position, and if you use your mobile phone to check, you may have to find a place for your mobile phone, which sometimes affects the driver's line of sight. If the position is not good enough, the driver may be distracted while looking at the navigation and may cause an accident. The car's built-in navigation is installed in a position with the best line of sight for the driver, so that there will be no accidents.

Moreover, the car's own navigation system is to display the navigation page all the time, but if you use a mobile phone to navigate, you may exit the page and you can no longer navigate, so the car's own navigation system is more easy to use.

Many people don't like to use the car's built-in navigation system, the main reason is that they need to go to the 4S store.

Make an update. Because when I first bought it, the car's own navigation system was not networked, and only after the update could I use this navigation system normally. Many drivers are too lazy to update, so they use their mobile phones to have their own navigation.

In addition, some drivers habitually use mobile phone navigation, so they will also find it very troublesome to use car navigation.

First of all, the car's built-in navigation system will not have no signal in remote areas, and if you use a mobile phone, there may be no signal in some rural areas. Then, the disadvantage of the built-in navigation is that you need to go to the 4S store for updates, and the car's built-in navigation needs to look down, which cannot allow the driver to see the navigation more quickly. The advantage of mobile phone navigation is that it can be placed in the driver's preferred position, so that the navigation can be seen more clearly.

In fact, both have advantages and disadvantages, mainly depending on everyone's habits.

It's very easy to use, and now the navigation system that comes with the car is very easy to use, which is more convenient, don't worry, there is no network.

It's okay, because the automotive industry is very competitive now, so all aspects are trying to improve and improve.

Some cars are not easy to use, so they can be brushed into other systems.

Automotive electronic navigation system is a new technology developed on the basis of the global satellite positioning system (GPS). Its principle GPS is a device that can receive positioning satellite signals, calculate the precise longitude and latitude of the car, as well as the speed and direction of the car through a microprocessor, and display it on the display.

GPS calculates the exact position of a car from any point on the ground (such as a car) and the relative distance of four positioning satellites in the sky. If we know the distance between a certain point and a satellite, we can know that the point must be on a spherical surface with the first satellite as the center of the sphere and the distance as the radius, if we know the distance from the second known satellite, we can confirm that the point is on a circular curve where two spheres intersect, with the third satellite we can intersect the third sphere and the previous circular line at two points, and generally through the distance of the fourth satellite, we can determine the latitude and longitude of the point.

In addition to accurate positioning, GPS also has the following functions:

It can directly enter the place name, latitude and longitude, ** number to retrieve the line, and quickly provide the best route to the destination; When the best route is not feasible due to unexpected circumstances such as road blockage, road section construction or taking the wrong road, a new driving route can be provided after re-retrieval; In order to make the driver understand the changes in the road surface in advance, it can make voice prompts, such as 500 meters before the general road and 1000 meters before the highway to explain the road surface conditions and the direction that can be changed to the driver; Before the car drives at the intersection, it can automatically realize the full-screen map of the intersection, specify the name of the intersection, the name and direction of the road after turning, which is one of the most important functions in the automotive electronic navigation. It can be said that the largest civilian market for GPS is car navigation.

GM's original navigation system is AutoNavi

Car navigation is equipped with GPS global positioning system function, allowing you to know your exact location anytime and anywhere while driving the car. The automatic voice navigation and best path search functions of the car navigation allow you to take a shortcut and travel unimpeded, and the integrated office and entertainment functions allow you to drive easily and efficiently.

Principles of navigation

Twenty-four GPS satellites orbit the Earth at an altitude of 12,000 kilometers above the ground in a 12-hour cycle, so that more than four satellites can be observed at any point on the ground at any time and at any time.

Due to the accurate position of the satellite, in GPS observation, we can obtain the distance from the satellite to the receiver, using the distance formula in the three-dimensional coordinates, using three satellites, we can form three equations to solve the position of the observation point (x, y, z).

Considering the error between the clock of the satellite and the clock of the receiver, there are actually 4 unknowns, x, y, z and clock difference, so it is necessary to introduce the fourth satellite and form 4 equations to solve it, so as to obtain the latitude and longitude and elevation of the observation point.

In fact, the receiver can often lock more than 4 satellites, at this time, the receiver can be divided into several groups according to the constellation distribution of the satellites, each group of 4, and then select the group with the smallest error through the algorithm for positioning, so as to improve the accuracy.

Intelligent vehicle is a set of environmental perception, planning and decision-making, multi-level assisted driving and other functions in one of the integrated system, it focuses on the use of computer, modern sensing, information fusion, communication, artificial intelligence and automatic control and other technologies, is a typical high-tech complex.

1 All 1, car navigation is divided into fixed and portable;

2. The fixed type is installed on different vehicles, because it is divided into many models, called "special car special type", but the functions are almost the same;

3. Portable, that is, the kind that is sucked on the front windshield, is suitable for all models.

4. Some high-end cars are originally equipped with navigation functions, but they also have their shortcomings: the navigation car is expensive (more than 10,000 yuan higher than the navigation car), the map upgrade fee is expensive (1000 yuan), and the use does not necessarily meet your requirements (there may be no handwriting input method, no U disk interface) and so on.

5. Suggestion: Don't buy a navigation version of the car, install a special car (such as Feige and other brands) special navigation, it will be good and cheap

Theoretically, as long as it is a car, then car navigation is suitable for all models. At present, most of the original configuration of the car has a navigation common function, even if the original factory does not have the model, it doesn't matter, now it is very convenient to install the original navigation.

Yes, it's just that some cars need to be installed by themselves.

Yes, some cars come with their own, and some don't have their own medicines.

No, the on-board system does not necessarily have a navigation function, and ordinary navigation must cover the functions of the car subsystem.

Navigation is just a function that people need in their cars. And the system is a platform that we can do with whatever we want to do.

So there must be a concept - the on-board system is not the same as navigation!

When every new thing is born, people will normally compare and classify what already exists. However, in today's rapid development of the information age, the Internet is also gradually penetrating into people's daily life. Represented by desktops, the Internet era has arrived; Represented by mobile phones, the rise of mobile Internet.

The era of the Internet of Vehicles, represented by the car machine, will be a key stage in the transition of human society from the Internet to the Internet of Things.

In the Internet era, Microsoft's Windows system is outstanding, and in the mobile Internet era, Android and Apple systems divide the world. So in the rising era of the Internet of Vehicles, which system will be able to achieve a blockbuster? Whoever does it will be the master of the next era!

This is the dream of Eagle Letter! We're doing things!
