About six or seven years ago, when I remember to accompany my friends to buy a car, the 4S shop added navigation for the buddy. This offer made him excited for a while and became the main deciding factor in his car purchase. At that time, being able to navigate directly on the car's central control screen was definitely a very high-tech and practical feature.
For those who often go out, car navigation is definitely a must-have function. With it, basically the days of opening and stopping, and asking for directions are basically gone. But as smartphones have become more powerful in the last three or four years, various map navigation apps have followed suit. By the time the 4G network has been basically popularized, not only driving, but also using public transportation, subway, walking, you can use your smartphone to navigate, and in terms of convenience and function, smartphone navigation has far surpassed the traditional car. navigation.
More and more car owners have chosen to turn on their smartphones while driving, using the Map App to navigate, and gradually abandoned the traditional car navigation. The reason why car navigation is slowly being abandoned by everyone is that there are many factors, but in the end, it is caused by many limitations of car navigation itself.
Unable to render live traffic
At present, in first-tier cities such as Beishangguangshen and Shenzhen, traffic jams have become a problem that office workers must face every day. Therefore, the first time to obtain real-time traffic information and choose a relatively less congested route, now it’s actually Has become a driving skill. The importance of real-time road conditions is not only reflected in the avoidance of congested road sections, including road repairs, road closures and various temporary road conditions, which can be reflected by real-time road conditions.
For most of the current car navigation, all the data comes from the offline download to the local "map pack", and such map packs are loaded locally and combined with GPS signals, the owner can only see relatively fixed map data. And it is impossible to get real-time change information of any road conditions. Therefore, when the road conditions are unfamiliar or when driving in the field, there will always be situations where you are forced to “squeeze into†a congested section or rush into a dead end.
This problem can be easily realized by smart phone navigation. The smart phone itself can be networked, and can update the data information of various map apps or suppliers at any time, which can not only display the real-time information of the blocked roads very intuitively, but even where it happens. The sudden occurrence of temporary traffic jams caused by traffic accidents can be notified to the owner at the first time. Therefore, in terms of real-time road condition acquisition, car navigation first lost in front of the smart phone.
Vehicle cannot communicate
The car navigation signal comes from the GPS receiver in the car, but in addition to receiving satellite positioning signals, it seems that most of our cars do not have the ability to accept other signals.
Smartphones are completely different. GPS, Wi-Fi, cellular data signals, various sensors, etc., all provide a basic source of assurance for navigation.
Communication between vehicles also plays an important role in navigation. Not only the real-time traffic information mentioned above, but also the vehicle traffic signal can obtain signals from other vehicles, provide mutual communication between vehicles on the road, can alert the driver to potential dangers and prevent accidents. It uses dedicated short-range communication technology to provide a range of data such as the position, speed, direction of travel, and braking status of the vehicle.
Slow calculation
Another problem with car navigation is that the limitations of hardware configuration have led to problems with slow calculations. Not only is the waiting time for planning a route or selecting a road too long, but some old car navigations may even crash.
Generally speaking, in order to save costs, auto manufacturers or accessory manufacturers will not be equipped with too good processor or hardware configuration for car navigation, and generally only follow the principle of “enough to useâ€. Therefore, this has led to the problem that most car navigation is slow in operation response speed, GPS signal reception and path planning.
Smartphone navigation has a unique advantage in this respect. At present, the hardware configuration of smartphones is updated very fast, and basically the mid-range configuration of smartphones can basically "snap" the configuration of car navigation in speed. . In contrast, for many car owners, smartphones are faster and more convenient to use.
Poor screen interactivity
If you are an old driver like me, driving a lot of different brands and models of cars, then basically change a car to re-familiar with the navigation system. At present, most of the car's central control system is developed by the car manufacturer itself. Therefore, the UI interface design including navigation is unscientific and the interaction is poor. I don't need to say that many people will have a deep understanding.
The screen is poorly interactive, and the most immediate hazard is to increase the risk of operation during driving. After all, if the operation is too complicated, then the driver will give more energy to the operation and selection of the navigation interface, and will not completely focus on the road ahead.
And smartphone navigation here once again puts the car navigation "step on the foot". It’s not just technology giants like Apple and Google who are very professional in the operation of smartphone systems, including engineers and product managers of various navigation apps who are also thinking about how to optimize the replacement of operations and improve the convenience of navigation during driving. . Therefore, various road conditions, intersection reminders, and signal speed warnings do not need to share the driver's energy.
Internet of vehicles and intelligence are trends
In fact, although there are many shortcomings in car navigation, it seems to be "stupid", but it still has certain advantages in many aspects. For example, it can be integrated with other functions of the car, the large screen looks more intuitive, and the GPS signal is stable. It is an advantage when compared with smartphone navigation. Therefore, car navigation cannot be completely replaced by smart phone navigation, and even Learn from the latter a lot of experience.
In order to solve these problems in car navigation, many car manufacturers have begun to cooperate with technology manufacturers to integrate the characteristics of smart phones into car navigation. These include the development of specialized in-vehicle systems and processors, the addition of networking capabilities for cars, the professional automotive operating system of Google Android Auto and Apple CarPlay, and even autopilot technology.
The "smart phone" of the car navigation system will undoubtedly solve all the problems mentioned above, and also enable car navigation to regain its own advantages and become the first way of car navigation.
The best thing to do now is undoubtedly the electric car pioneer Tesla. Tesla not only has a large touch screen for its Model S and Model X models, but also provides a dedicated processor and in-vehicle system, and the in-vehicle system can also be like a smartphone through the built-in LTE network module. Perform an OTA upgrade so that the car can correct any existing deficiencies or add more new features at any time.
Therefore, in order to make car navigation no longer "stupid", intelligent and networked is the most fundamental way to rediscover the "status" in the minds of car owners, and it is also the future trend.
