Originally developed in the smart phone, tablet computer iOS, Android embedded application system, in the automotive intelligent development trend, this type of embedded system has become one of the popular solutions for automotive intelligent platform, especially the end user has passed the smart phone Tablet PCs are familiar with the Eco System of embedded systems, and there are relatively many peripheral application development and integration resources. You can also use abundant resources to accelerate the development of related applications...
The automotive industry follows the global market trend of environmental protection and emission reduction. The development and design of vehicles has been continuously revised to focus on “energy savingâ€. It is no longer the design direction that emphasizes “performance†first. Biomass fuel, hydrogen fuel, fuel cell, solar cell, etc., with multi-power source for product integration, with Hybrid oil/electric hybrid design, gradually become the stage of the pursuit of environmentally-friendly power development, however, Hybrid can not To achieve the goal of complete zero emissions, all electric drive vehicles can be flexibly converted into power solutions for energy storage and reuse through various energy sources. Instead, they can combine the flexibility of use of clean energy with the power demand of actual vehicle operation.
When the power source of the car is converted from fuel to electric drive, the in-vehicle computing and vehicle intelligent entertainment system, which was originally slow to develop, has become another important selling point after the car has been energy-saving issues, from the perspective of vehicle safety. / Passive safety automation mechanism, combined with Netcom's in-vehicle digital entertainment platform, and even the intelligent automatic driving function of integrating IoT IoT applications, has become a major driving force for the development of automotive intelligent computing platforms, attracting such as google, Apple, Baidu, etc. The industry actively participates in the participation, even if these operators first intervene in the car entertainment applications with low threshold and looser verification conditions, they use the habit of observing the car for 5 to 10 years to get the car entertainment in advance. The platform, on the other hand, is the active target of the in-vehicle intelligent system industry.
Apple Carplay has interface and voice recognition advantages
Observing the development trend of the existing car multimedia system, because Apple still has a leading position in the embedded system platform, voice recognition and other interfaces, and its iPhone, iPad mobile device products lead the mobile application market trend in optimizing the use experience. Developed an application ecosystem that is different from the general 3C product design but allows users to enjoy the application. In addition to the popular market for mobile devices, Apple plans to enter the smart car application market through the Carplay embedded platform. Apple is actively attacking. The action of the in-vehicle application platform is quite obvious.
With Apple Carplay's product positioning, it provides a smart application platform that is consistent with each car manufacturer, and can integrate the original Apple's iOS experience optimization results into the smart application platform of the car, because most of the major car manufacturers will still resources. In terms of car R&D and optimization of power performance, bets on the in-vehicle computing platform, in-vehicle entertainment system related technologies and resources are less, and the introduction of Carplay platform is making the car computing platform easier to use, and the car factory is also sustainable. Its model development.
4G Lte strengthens mobile data access capability
The development of intelligent vehicle platform has recently caught up with the development trend of mobile communication network applications. From the 3G/4G Lte high-speed mobile data transmission application, the on-board computing platform can also achieve high-performance transmission performance close to or even beyond the solid line network. It can meet the high-speed network application functions that mobile communication applications cannot support in the past. For example, digital entertainment applications such as music streaming and high-definition video streaming can support digital entertainment applications. Now, the data transmission module can easily support the in-vehicle computing platform. Resolution video/audio playback, this development trend also attracts large network service providers to actively invest in relevant application development. For example, Google, Baidu, etc. launched the Android Auto, Carlife platform to grab the application market of intelligent in-vehicle systems.
The in-vehicle computing platform itself is an excellent Internet O2O application portal. The in-vehicle computing platform screen has also become a strategic position for major network operators to actively seize, especially in IoT applications, 4G Lte high-speed network support, and even a variety of mobile entertainment in application integration trends. Under the circumstance, the system operators who grab the on-board computing platform basically have the ability to lead their users' on-board platforms, and can even further expand the core service influence based on this development of more innovative applications or platform services.
On-board computing platform performance and specifications are high
In the public network service providers actively compete for the vehicle platform, it also promotes the comprehensive upgrade of the car's on-board computer and car performance and functional aspects, in order to meet the operational and value-added functions required for smart car applications, such as traditional car and car. Most entertainment platforms only need CD and DVD playback requirements, and even some additional MP3 digital music playback requirements. However, the new-generation in-vehicle computing platform needs at least a computing platform with the same specifications and performance as smart phones and tablets, and even needs to have a desktop computer. Computing and storage resources, while the vehicle smart platform also needs wireless network communication, data storage, real-time data analysis capabilities, and promotes the specification of on-board computer specifications to expand the more advanced intelligent in-vehicle application functions.
In addition, if the on-board computer platform needs to extend the functions such as 360-degree vehicle-wide photography, lane recognition/vehicle distance sensor, road marking number identification, road marking offset warning, etc., the on-board computer must support the corresponding sensor and application mechanism. The need for device connection, and such applications require more rapid, real-time system processing and feedback, which will require higher performance for on-board computers, not only for music playback, video playback needs for multimedia applications, but also comprehensive The architecture and system performance are improved. At the same time, the system platform must be integrated with various vehicle sensors. The actual integrated design is quite difficult, and the system platform must be verified by the vehicle level.
Third-party vehicle platform needs to strengthen content integration and grab the application market
If the on-board computer itself is only an additional function application, for example, car navigation system, music, multimedia playback system, radio, mobile digital TV and other application functions, it is an easy-to-cut application market for third-party service providers, and it is also a majority of non-depot manufacturers. In the background of network services and software application service providers, such as Carplay, Android Auto, and Carlife, the third-party application integration is mainly used to grab the in-vehicle computer platform application market, while the advanced integration is still in the car factory. Integration is the main factor.
As for the car networking concept attached to the car computer, the integration concept is derived from the Internet and the mobile Internet. The Internet is a network link between PC and PC or various computers, while the mobile Internet is a network link for various mobile phones and mobile devices. The network system formed by interconnecting vehicles as the unit, the network nodes are similar in function from PC, smart phone/tablet computer to automobile application, and can realize automobile data collection, sensor data collection and processing, transfer driving data and even satisfy the terminal through the vehicle network. The roadside monitoring needs of users and road managers reduce traffic costs and improve management efficiency through transparent data transmission and high-performance management mechanisms.
Intelligent vehicle platform optimizes vehicle demand
For example, when the user's car has an engine fault light, in fact, the owner of a traditional car can only worry about what causes the engine to fail. If the vehicle can barely drive, the owner can only drive the vehicle back to the repair shop for maintenance, but if With the vehicle-mounted computer platform and the car networking service connection, the fault status can be transmitted back to the service system in real time in the power system. The back-end service system confirms the current vehicle position and signs of failure, and returns the user's vehicle to inform whether it is suitable. Continue to use the vehicle, or dispatch a towing vehicle to recover the faulty vehicle from the vehicle maintenance system to avoid more safety concerns caused by the faulty vehicle.
The integration of the vehicle networking system and the on-board computer, the application function is not limited to the integration of the vehicle fault prompt and the follow-up professional maintenance system. If the vehicle network can connect to the platform of the intelligent transportation system, it can even provide a safer car-to-car and vehicle. The IoT communication of the facility will enhance the application of intelligent driving, further improve driving safety, increase road control and ease the processing efficiency of traffic.
It is difficult to develop a unified vehicle hardware platform. Indirect use of the car screen has become a development path.
From the perspective of the Internet, the node connecting the network is a PC computer, the processor may be x86, the operating system is Windows/Mac OS/Linux, and the mobile phone, tablet, and processor of the mobile network may have ARM/x86, etc. The operating system may be different embedded system platforms such as iOS/Android/Window Phone. As for the on-board computer, it is more complicated. It can be advanced to the PC computing platform of mobile or vehicle board, or ARM/low with only mobile devices. The x86 computing environment can be supported, and the intelligent on-board computer terminals provided by different car manufacturers may have great hardware structure and specifications. How to achieve interoperability/interconnection is basically not easy and the difficulty is quite high.
The current market is that there is no common standard, and without the standard premise, each manufacturer wants to push for the technical standards that are beneficial to them, and it has become the key to the success or failure of the screen of the vehicle computing platform.
However, the actual situation is that the on-board computer platform is mainly pre-installed by the car factory. For different car platforms such as CarPlay, Android Auto, Cralife, etc., it is necessary to compete for the favor of large-scale car manufacturers. The car factory supports enough brands and can pass a certain degree. The scale of the economy makes the introduction status develop in the positive direction, and then forms the system standard of the on-board computer. However, even if the system is pre-installed, it is still quite difficult. For example, the on-board computer must provide the corresponding hardware platform according to the requirements of the embedded system of the vehicle, but Different embedded platforms have different hardware requirements. On the other hand, the demand for on-board computers of a single model or even a brand may not be able to reach the economic scale of configuring the corresponding hardware platform, forming a limitation of the development of the computing platform for smart vehicles.
Interestingly, after the early encounters were difficult to import, Apple Carplay, Google Android Auto, and Baidu Carlife found another mechanism to provide a connection between smart phones and tablets through the smart car platform. The prepared smartphone and tablet pre-loading the App software for the car, projecting to the screen form of the on-board computer through the operation screen mirror, and let the on-board computer operate like the usual mobile phone and tablet computer operation interface, while Carplay, Android Auto or even It is also necessary to change the vehicle application into a human-machine interface suitable for driving touch operation, which is used to avoid the technical bottleneck of configuring a dedicated vehicle system platform.
