This decade is all set to bring in ADAS features in mainstream passenger cars. With surround-view being at the low end of the market paving way for other ADAS features. This brings in for users to ask what is the next in automotive ADAS. In this article, we look at some of the new trends for 2021 in automotive ADAS
1. Sensor fusion
Automotive sensors have come a long way from ultrasonic sensors to stereo cameras and lidar sensors. However, there is a significant gap in what each of these sensors can do as a standalone sensor. As vehicles become more autonomous or L3 and above there is a constant need to fill this gap which helps in surround mapping more accurately. Some of the common applications that employ sensor fusion are Automated parking, Automatic emergency braking, lane change assist, and more. Read on more about sensor fusion for L3 and above here

2. Embedded Vision
Automotive ADAS systems are used for potential hazard identification on the path. Few ADAS features just give out a warning to the driver such as BSD, LDW. However, as we move further up towards full autonomy just a warning won’t suffice, cause the car itself should be able to take the necessary decision. For applications such as automated parking, traffic sign recognition, lane mark detection for automatic speed change, and lane change. This also is the stepping stone for a driver monitoring solution which helps in identifying drunk driver and monitoring driver in-attentive monitoring.
3. Connectivity and 5G
With cars getting smart OTA is picking up a lot of traction, this helps OEMs to push upgrades to their cars and make the best use of existing sensors and hardware setup. This also helps in updating the cars for cybersecurity. With 5G technology, this process is sped up and also helps OEMs to keep their offerings more relevant in the market.
As autonomy level increases driver involvement in driving reduces considerably. To address this issue, one needs an intuitive interface system not only for the infotainment system but also for the driver to interact with the ADAS system. Things like AR and heads-up display are also picking up pace thanks to the way they interact with the users and making driving a more immersive experience.
5. Software Infrastructure and Autosar
The number of electronic/ electric systems and the complexity of these systems are increasing in modern vehicles. Autosar is a development partnership for parties working on automotive software. They provide standardized open software architecture for automotive ECU. Modern vehicles have more than a hundred ECUs each. Every one of them has thousands of functions. Without following the standard, software development is most likely to be rewritten when the ECU hardware design is changed. Autosar facilitates software development independent of hardware, with the standard software is more transferable. This means software can be easily shared between different vehicle systems largely independent of the system’s underlying hardware, which AUTOSAR improved by standardizing component interaction. In the past, and still today, most component software is developed according to the hardware it will be programmed on. AUTOSAR reduces this constraint by implementing a standardized interface between application software and its hardware to allow for hardware-independent component software.

ADAS technology is here to stay, thanks to the quick adoption and advances in semiconductor technology that we have seen in the last decade. A simple feature like surround-view which was available in high-end automobiles is now available in mass-market cars and the same goes for park assist and automated parking. With this accelerated growth one can expect L3+ autonomy and AD cars on the street by end of this decade.
