In recent years, Apple's mobile phone attracts much attention, which almost become a global benchmark for mobile phones with its elegant appearance and powerful. With Android phone system was also hot as Apple, whixch aslo known for its open source code, custom rolling process and the same powerful features, but it has a more personalized setting and quickly occupied the large country.
Here the reader will certainly have to ask, you say this is not a car navigation it? How are you pulling endless phone? Dear readers, Shaoanwuzao. Let us first look at several software.
Is the spiritual leader Dopod 2008 Dopod Figure Skywalker customized version of its performance overall. Powerful. Highlight is a powerful figure with spiritual support to the user navigation.
This belongs to Google's mobile phone navigation software, will naturally have a "Google Earth" data, and accurate positioning, a large amount of data, if you have enough traffic, it may be anywhere in the world as you navigate.
This is a platform in the Apple and Android are highly popular navigation software. Packets can be downloaded through the network, placed in the phone memory card, not only to save traffic, can also improve speed.
When the smart phone can navigate this work, one can not help asking, car navigation, and survival space and necessary?
Of course, many of my friends to ask, the phone's GPS to car GPS, and compare it true? First of all I should declare here that, in fact, a lot of friends on the phone's built-in GPS are more or less will be misunderstood, in fact, is the need to navigate through the phone in the phone built-in GPS chip, and the general's car GPS navigation systems navigation principle is no different, the only difference is that the phone's screen may be small or GPS navigation device can be added more features (car theater, car music player, etc.). Air principle is no different, the only difference is that the phone's screen may be small or GPS navigation device can be added more features (car theater, car music player.
Car navigation application has been developed as the main navigation device manufacturers in the smart phone is reduced to a supporting role in navigation. This is understandable things. Smart phones and navigation systems can not be the same as car navigation systems, easily priced over one hundred thousand yen. If only because GoogleMapsNavigation price if the application is free. Even in a very low price of competing smart phone navigation market, it is difficult to increase profits. Therefore, most manufacturers navigator smartphone navigation with distance. However, recently there have been many car navigation systems will cooperate with attempts to smart phones. For example, Fujitsu Ten in July 2011 listing of navigation through the "iPhone" is equipped with the developed application can be displayed on the screen in the navigation information obtained by the iPhone. In co-operation this point, further is Denso. The company has developed a smart phone as a car navigation user interface (UI) to use the application "NaviCon". Through the "iPhone" screen for the conversion of the map and destination settings. For example, when conversion map on the iPhone, navigation map screen will also linkage conversion. Navigator smart phones than the simple UI. So they had a Denso take full advantage of the iPhone UI to make up for weaknesses in the idea of navigation.
It can be said that with the rapid popularity of smart phones and smart phones rise navigator, navigator and manufacturers there have been slowly turning to smart phone navigation signs. Of course, these also are not at this stage from the car navigation system is essentially a move.
Transmit CAN messages to smart phones.
Recently, however, there are companies expected to make an attempt to break the line. Toyota recently in the "new generation of automotive industry exhibition 2011" (June 2011 15 - 17, Tokyo Big Sight International Exhibition Center) will be on display route guidance and other core functions of car navigation systems by all the smart phones (and the data center) to take the car navigation prototype machine. The prototype machine will be intelligent through the HDMI cable to connect phones and car navigation, you can transfer to the car navigation device from the smart phones (and the data center) operator to obtain the route navigation screen and voice. But also to send images via wireless LAN, using Bluetooth to send voice. As a result, car navigation systems on display just a simple one.
This product-based navigation, the past can no longer use those expensive car navigation systems. Can even say that is no longer a need for car navigation systems manufacturers. Because of the important functions of car navigation device can be used to implement the smart phone.
Of course, this does not mean that smart phones will be able to replace all the existing car navigation function. The reason is that car still bears the conductivity meter and the suspension and brake control system to send location information and other functions. Maybe the smart phone is still hard to take the relationship with the vehicle safety control system to send information tasks. To achieve this, the development still requires extensive knowledge with the car. This is replaced by phone navigation car navigation systems all feature the biggest barrier.
However, this barrier may be broken in the future. Toyota is developing this system, there are related to try. Because the system can send a car to the smart phone LAN "CAN" in the steering operation signals transmitted control information. This makes quite surprised. Because the emphasis on safety and reliability of the car manufacturers generally control the operation of the information very carefully. In case of malicious intrusion from outside the CAN message, then it may lead to serious accidents. Most manufacturers usually try to take the CAN external network isolation practices. But Toyota is aware of this risk in the case, still to achieve the external network connected with CAN-challenged. It is reported that Toyota's car navigation prototype machine is set on the gateway, the gateway as a security gate, and then to smart phones and CAN information exchange.
In the future, may really be able to smart phones (and data centers) to control the vehicle control information, and send it to the vehicle. By then, the smart phone navigation car navigation systems can completely replace the.
