Maybe two or three years ago,Jiangmen vehicle navigatorIt's a very high-tech product. Actually, for us road addicts, the significance of navigation is appropriate and serious. It seems cool to set up navigation when we get on the bus. However, after one or two years of development, most driver friends, including our team, have begun to abandon car navigation and use mobile navigation. By comparison, Mobile navigation is more accurate, and the speed of real-time update is also very fast. Therefore, whether we test drive tens of thousands of domestic cars or millions of luxury cars, and the mobile phone support is always standard, then our problem also comes. Is it necessary for mobile navigation to carry out car navigation today?

When it comes to car navigation, the principle is appropriate and simple, that is, put the preset map device on the storage card, and then contact the GPS module in the car with wechat, so that the movement of the passing vehicle will not stop at the fixed point of the storage card, and then connect it to be a driving road. At present, the vast majority of on-board navigation is not connected to the Internet, which leads to a problem. That is, the reality of the road situation cannot be displayed on the car navigation screen to prompt the driver to change lanes and detour, which is also one of the biggest disadvantages of car navigation. To obtain the latest map, you can only unplug the memory card and download and update the latest map, However, with the changing speed of China's road conditions and the almost non-stop construction of roads, this update is obviously difficult to keep up with the speed of road conditions.

Another drawback is that in my opinion, navigation and music must use the same set of sound, which disturb each other. Especially when we are listening to some good songs, the navigation sound often comes out to make trouble. For example, when we hear "the boundless horizon is my love", when we first arrive at "me", the sound of "turn left at the intersection ahead" is announced by the stereo, followed by "my love". It may affect people's interest in listening to music or crying and howling in the car. For drivers who listen to music every time they drive like me, such frequent interruptions are obviously unacceptable.

After talking about the disadvantages of vehicle navigation, we have to talk about the advantages of mobile navigation, which is now very obvious. Mobile phones are connected to the Internet, and the background of many mobile navigation software itself is a big data analysis center. In addition to providing the most basic navigation services, it can also be based on the mobile speed of mobile phones equipped with this software on the same road The frequency of stop and go is used to judge the congestion on the road and prompt the driver to respond.

In fact, compared with vehicle navigation, the biggest advantage of mobile map is the realistic update of road conditions. It's almost a little slow ahead. We can get a prompt immediately. If the vehicle equipped with the same software in front moves in the same direction or turns around, the software can also respond through data collection, prompt the vehicle to pay attention and change direction or turn around. We can drive closer and have a look, There must have been an incident, maybe a road closure. At the same time, these software can also prompt the driver whether to go uphill or downhill and which lane to take when presenting the road fork, which is really very heart-to-heart for the driver friends driving on the more complex overpass road conditions (such as Xizhimen overpass). In this way, a mobile phone software can almost help us deal with all the traffic problems on a strange road, whether it is road planning or speed limit capture and so on. These are difficult for off-line vehicle navigation.

The most important point is that mobile navigation does not have to pull out the card to upgrade like car navigation, but directly upgrade and update online. For drivers, it undoubtedly saves a lot of things. The condition is that they need to spend some traffic costs, but it is more convenient. This cost is really not worth mentioning.

Of course, mobile navigation also has disadvantages. In places with poor signals, there is nothing we can do, and maps and road planning are delayed. In these places, the advantages of vehicle navigation are reflected. The maps are prepared in advance, and the mobile phone models are not good. Ordinary roads are rarely diverted. It is likely that these local residents are particularly sparsely populated. This is one of the disadvantages of mobile navigation, but if mobile navigation makes an early offline map, this disadvantage will be easily made up for.

It's obviously wrong to kill the on-board navigation. After all, many manufacturers are also pushing the so-called Internet cars. One of the biggest advantages is the Internet of vehicles. To put it bluntly, the problem that the on-board navigation can't be connected has been eliminated, but more manufacturers are beginning to carry systems that directly map the hands to the vehicle's big screen, One of the intentions is to use mobile navigation instead of vehicle navigation. We think this is also a development direction of navigation products in the future. Of course, if driverless cars become the mainstream, it is another matter. For ordinary cars, vehicle navigation has no advantages.
