Body network increasingly complex gateway applications come to the fore

The vehicle gateway (Gateway) will play an important role in connected cars. The design of internal and external communication networks of connected cars is becoming more and more complex. One car may contain several wired/wireless communication centers at the same time. In order to improve the convenience of communication data exchange inside and outside the car, the importance of the car gateway role will be significantly improved, and the car chip maker It has also been competing to offer gateway solutions that cater to a variety of communication interfaces.

Lin Guanhong, senior application engineer at Freescale, said that connected cars are an extension of the Internet of Things (IoT) concept. In addition to the connection of the internal network of the vehicle body, how to make the information and external communication and communication in the car is also an important test; At present, most of the external communication of automobiles must be based on the mobile devices of the vehicles as the intermediary medium. In the future, V2V communication such as V2V and V2R will be popular, making the communication of connected cars more convenient and reliable.

Lin Guanhong further analyzed that different applications in connected cars will be controlled by different communication centers, such as the vehicle engine control system by the control area network bus (CAN Bus), high-speed teletype control (X-by-wire) system. The use of FlexRay, audio and video multimedia networking using Media Oriented System Transport (MOST), and other CAN FD, Ethernet (Ethernet) audio video bridge (AVB) and other communication technologies to enhance the complexity of connected car body network .

At the same time, the design of the body network must also consider the design of increasing network bandwidth, improving data transmission security and body safety warning mechanism, so that the electronic control unit (ECU) in the car is increasing, and the body network and connection The point design is therefore more complicated.

In view of this, chip vendors began to propose a gateway concept that can serve as a communication convergence hub, and released related chip solutions, hoping to consolidate the past decentralized communication control centers into one place for the exchange of communication data; For example, the chip supports a variety of network communication interfaces, such as Ethernet channel AVB, FlexRay, media local bus (MLB), universal serial bus (USB), CAN FD and two-wire regional Internet (LIN) bus, etc., and use a three-core multi-core architecture to ensure efficient data transfer.

Not only that, but in addition to the comprehensive support of the communication interface, the vehicle gateway must also be able to measure the safety and power saving design.

Lin Guanhong pointed out that there are currently about 40 microcontrollers (MCUs) in the car, and the number is expected to increase to 70 to 80 in the future. Therefore, Freescale's communication gateway solution also has Pretending Networking. The MCU, which is responsible for communication functions, can be freely deployed to enter sleep and standby mode to save power. In addition, the solution also provides hardware security module (HSM), AES encryption algorithm, secure memory and secure boot function to protect communication data.
