In July 2014, in a closed highway in Florida, Governor Rick Scott, in a automatic driving Audi A7, a speed of 40km / h. In just a year, Audi announced that it will use a higher-level Tegra X1 chip. This chip has machine learning characteristics, which will make the car truly "think". This is in 2012, Audi applies Tegra 2 to the mass production vehicle, only for the past three years. In the same year, Tesla's Model S began to mass production. The car also equipped two Tegra series chips.
Yingda: Car intelligent division three steps
In the era of intelligent, Ying Weida found a new business growth point. This process will take three steps in general:
The first step is to enter the dashboard and the center control screen. In particular, the instrument panel is gradually transition from the mechanical dial to the liquid crystal dial. More and more models, replace the dashboard directly for an alien TFT screen. Similar to the transition from the mechanical watch to the electronic watch. Due to the key information such as speed, speed, gear, the instrument panel is highly required to ensure that the frame rate is first ensured, followed by ensuring the rendering.
In the second step, it is a bus system that enters the car. The bus system has the most popular CAN protocol, as well as MOST, FLEXRAY, LIN, etc., which constitute a local area network in the car, and connect hundreds of ECUs together. In this LAN, there will be a large amount of data operation needs, the simplest example is the shift logic problem of the automatic gear gearbox.
The conventional gearbox is determined based on the accelerator pedal and the brake pedal, to determine the rise and downship. However, GPS applications, as well as the intervention of big data principles, which can be transmissively shifted more intelligence, which requires an in-vehicle CPU to complete the operation.
The third step is to enter the automatic driving system. For example, Audi A7 automatically drives prototypes, which is equipped with a Tegra K1 chip to operate the huge data generated by automatic driving. This chip is located on the ZFAS motherboard at the trunk of the vehicle trunk, which is responsible for operations from the camera and various sensors, and the output tells the car what to do.
TEGRA X1 chip, computational performance is more powerful, will apply Audi future automatic driving models
The TEGRA K1 chip has a quad-core ARM Cortex CPU, and a 192 core Kepler architecture GPU. Audi A7 is the application case of the first time in the car. In addition, K1 is mainly used in consumer electronics, such as Yingda Shield tablet, millet Mipad, Acer's Chromebook 13, etc.
It is not ignored, and the car will become another new mainland of the Tegra chip. According to IHS predict, the global passenger car sales will reach 88.6 million in 2015. In addition, according to Statista's included, 2015 tablet shipments will be 332 million. There is no doubt that the car will become another mobile platform for huge growth rates and protective number after the mobile phone, tablet, PC, and TV.
Qualcomm: Wireless charging prospects are wider
On the first season of Formula e, BMW I8 used to do safety vehicles has won a lot of attention. This car is equipped with HALO wireless charging technology provided by Qualcomm. Next, this technology will also be applied to the F1 car of Formula E.
Qualcomm is known for its semiconductor equipment such as mobile communications, microprocessors. But you have to know that Qualcomm is in the field of wireless charging, especially electric vehicles, and is in the world's leading level. In 2012, Qualcomm jointly established A4WP Radio Energy League. At present, Qualcomm's HALO wireless charging technology has signed cooperation with Renault, BMW, Formula E.
Wireless charging technology, the basic principle is electromagnetic induction. At present, there is a qui standard, which is developed by the WPC Alliance. Qualcomm's HALO technology, including WiPower technology, wireless charging, is based on a Rezence standard. Rezene is customized by the above A4WP alliance. For electric vehicles wireless charging, the biggest problem is the energy conversion efficiency. Compared with the cable charging, a large amount of electrical energy is converted into the passage of the BCU (base) and the VCU (vehicle end) in the BCU (base) and the VCU (vehicle end). Efficiency is big and discount, about 40%.
Qualcomm Electric Vehicle Wireless Charging System (WEVC)
For example, take the LEAF electric vehicle as an example of Nissan. The car battery pack has 24KWH, if used in wireless charging, it takes up to 20KW to take up to 1 hour. This is ok, but there will be many energy in the middle. In fact, wireless charging has no intermediate medium, theoretically under ideal conditions, the charging efficiency should be comparable to the line. Line accommodation efficiency is generally 70% -80%. At present, there have been companies to showcase wireless charging of up to 98% efficiency.
Back to Qualcomm Halo. For the study of wireless charging, it will undoubtedly let Qualcomm have cooperative chips in the car factory. BMW i8 security car is the result of the "case" BMW executives in Qualcomm executives. Although there is still a certain period of time from a wide range of civilians, wireless charging in a particular occasion has been able to play. For example, Formula E, the bottom of its track can be fully laid a wireless charging base. This will not be used to change the car. Because a electric F1 is only 20 minutes.
BlackBerry: carplay is actually standing on our shoulders
When Apple's carplay came out, the media exposed its cooperation with BlackBerry. Because CarPlay signed a car enterprise, it is basically a customer of BlackBerry QNX system. So Apple and BlackBerry, jointly developed Carplay. BMW, Audi, Volvo, Modern, Ferrari, etc., most of the car brands are based on the QNX system.
Audi's TFT dashboard is based on QNX-based Car Platform architecture.
QNX has more than 70% of the market share of the in-vehicle system. Leading Microsoft Windows Embedded Automotive, as well as Linux. In addition, the main customer of Microsoft's WEA platform is also turned to the QNX platform. This Car Platform is a car entertainment information system program for QNX. It includes QNX Neutrino real-time system, mobile communication module, noise reduction system, can support Qt and HTML5 HMI (Man Up) scheme. Audi's new TFT dashboard, made a good ad for QNX this platform. , Reading the full text, the technology area
