Take you into automotive electronics
A number of new technologies have emerged in automotive applications, including improvements in power systems, very complex telematics, and autonomous driving. Today's cars have more electronics. However, as features such as Advanced Driver Assistance Systems (ADAS) become standard, rather than expensive options, more advanced functional modules will enter the homes of ordinary people.
Some changes are quietly being realized by improving wireless camera sensors, processors and memory, software, and even human-machine interfaces that require real-time integration. Here are some of the latest technologies and how their relationship with other technologies makes them even more important in automotive applications.
Currently, CAN and LIN are still the mainstream control buses used in automobiles, but CAN-FD, FlexRay, MOST and Ethernet are also mixed, some of which are part of the IVI system, and ADAS sensor connections are added to these application combinations.
The RJ-45 jacks and CAT5 and CAT6 are hard to find under the hood, and the OPEN Alliance SIG's 100BASE-T1 and 1000BASE-T1 use a simpler wiring method. The IEEE 802.3 standard includes 100BASE-T1 in IEEE 802.3bw-2015 clause 96, which allows conventional microprocessor wiring with an Ethernet connection.
Currently, time-sensitive networks (TSNs) are being used in cars, at least in terms of IVI for audio and multimedia synchronization. TSN actually turns on audio-video bridging (AVB) support for automotive applications.
However, not all car communications require wiring. Wi-Fi access points, as well as wireless communication functions such as cellular links, can already be set up here, and more communication methods will be adopted. Vehicle-to-vehicle (V2V) and Vehicle-to-Infrastructure (V2I) are part of the V2x portfolio, designed to improve ADAS and provide more environmental information for autonomous driving.
If you have a better display, the IVI and ADAS systems will work better. Many technologies that have been proven and popular in other applications, such as OLEDs, are entering the concept car to provide curved display and a better viewing experience.
Head-mounted displays (HUDs) are becoming more common and complex, providing more information in a larger space.
TI applied its DLP technology to HUD. Its DLP3000-Q1 digital micromirror device (DMD) and chipset have received automotive certification. The platform that provides a 12 degree field of view eliminates the need for a light source and does not require a bias source, which means that the system does not conflict with glasses with polarized lenses.
We have been talking about all the high-tech cars entering the car, however, low-end technology combined with some high-tech support can provide users with an interesting solution. It uses a smartphone to display information and uses the same implementation as other HUDs. The app can display speed based on the sensors in the smartphone. This is different from the car HUD, the cost of 30 dollars is a difficult threshold to pass.
