New Sensor With Artificial Intelligence, Car Auto-driving Technology Ushers In New Development

- Oct 16, 2018-

From the recent European MEMS & Sensors Summit in Grenoble, France, it is clear that sensors are becoming more complex, sophisticated and extremely intelligent, and continue to be popularized in modern times. Various areas of life. As sensors continue to collect vast amounts of data to automate vehicles, cities and factories become smarter, we see many requirements for sensor fusion, edge artificial intelligence (AI) and data privacy issues, and more and more Medical applications for biosensors.

The keynote speakers and participants who participated in the event enthusiastically discussed the powerful sensor ecosystem currently under development in Europe. For example, we recently reported that a consortium is developing mid-infrared photonic ICs for detecting gas leaks; British researchers have designed devices that can be paired with handheld CMOS sensors and Android mobile apps to easily measure chronic heart disease or prostate cancer at low cost. Earlier this year, we also reported on Oura Health, which encapsulates PPG sensors in the ring to measure various heart rate parameters; Oticon integrates sensors and processing capabilities into its hearing aid products to extend capabilities beyond hearing aids.

At this year's summit, industry leaders such as Bosch Sensortec, Infineon, NXP and STMicroelectronics (ST) have emphasized that their diverse sensor solutions are suitable for From technology to autonomous vehicles and other applications, the technology demonstrates and provides a platform for innovative or emerging companies developing sensor technologies such as MirSense, IRLYNX, Xenomatix and Tusk IC.

This annual conference is actually divided into two parts: one to discuss MEMS and sensors, and the other to focus on image sensors. But from the final intent and goal, it is a meeting about sensors, and the key to sensor fusion is to emphasize that the system depends not only on one sensor, but on multiple sensor inputs. Whether it's autonomous vehicles, smart cities, future factories, or healthcare, sensor subsystems typically include multiple sensor types from different sources—measuring parameters such as temperature, pressure, proximity, and position, as well as a variety of chemicals and gases. To implement a closed circuit system for tracking, interpreting and feeding back relevant information.

This is most evident in the automotive industry, where it must deploy a combination of vision, radar and other sensors to help developers ensure that the vehicle is safe to drive in autopilot mode.

Lars Reger, senior vice president and chief technology officer of NXP, said that sensors account for the most important semiconductor value in autonomous vehicles, and that in order to ensure absolute safety, the combination of visual and radar imaging sensors provides drivers with more Great confidence.

Luc Bourgeois, head of Renault's Advanced Driver Assistance Systems (ADAS) and Automated Driving (AD) Systems Engineering, also talked about the need to use complementary sensor technologies including car-to-X, radar, light mines, cameras and sonar. He emphasized the role of sensor fusion in constructing a digital representation of the world, not only helping to master, but also making decisions and analyzing risks, especially big data and artificial intelligence (AI). The role.

Despite the promotion of the development of fully automated vehicles, the reality must also be considered. In a briefing on the smart city, Claus Habfast, vice president of the Grenoble Municipal Council, said that vehicles in many cities in Europe have been unable to achieve full automatic driving for many years. He said that smart mobility is a key element of every smart city strategy. A driverless car or a networked autonomous vehicle (CAV) must rely on seamless communication with other vehicles, as well as sensors and external infrastructure for data processing.

However, he said: "This trusted CAV infrastructure is not yet in place. Someone must deploy and operate and get investment compensation from the owner and/or user of CAV. No one can point out who will be in the city yet. I am responsible for this problem, and I don’t know how to generate income and distribution.” He added: “When CAV must coexist with ordinary vehicles, if it does not develop into a luxury vehicle, it will only worsen traffic and traffic jams.” Nevertheless, he believes that due to the extensive public transport customer base in Europe, the city authorities are ready to play a leading role in the development of CAV infrastructure.
