CAN FD can accelerate AI in 5G V2X and AIoT smart manufacturing applications

Wed, Apr 26, 2023

Capitalising on the growth in the V2X (vehicle to everything) market, Antzer Tech, a subsidiary of Innodisk, has introduced the CAN FD series featuring high speed transmission, large data capacity, and downward compatibility. It is suitable for customers worldwide in the fields of electric vehicle, self-driving cars, and unmanned systems using mass data.

CANbus has been indispensable for traditional telematics, explains Antzer. Not only does it simplify wiring, but it realises highly reliable communication without host computers. As more IoT and V2X applications emerge, however, data loading also increases which could result in latency. The GADN-FD7L0 and FARO-FD700 offer high speed performance, and CAN standard downward compatibility for a painless smart upgrade, said Antzer Tech.

The CAN FD solution by Antzer Tech addresses the limitation of data transmission speeds and increases the data payload capacity by eight times compared with the CANbus network. 

For example, in telematics systems, it collects multiple system data of power management, radar sensing, cameras and GPS non-stop. According to Antzer, the CAN FD can break through the limitations of CANbus and contribute to unmanned smart manufacturing and logistics systems, despite the complexity of data transmission in these sectors. 

In addition, the CAN FD features high fault tolerance and debugging capabilities to enhance data reliability.

For safety requirements, it complies with the industry-level wide-temperature standard and features GNSS (Global Navigation Satellite System) and UDR / ADR  (untethered dead reckoning / automotive dead reckoning) functions to offer accurate positioning in tunnels, mountains, and other environments with unstable signals. This capability helps to increase transportation safety and optimise management as for unmanned telematics systems, said Antzer.

Innodisk provides flash memory, DRAM modules, and embedded peripheral products for industrial and enterprise applications.

Dedicated software library accompanies MEMS inertial sensing module 

Mon, Apr 24, 2023

The ASM330LHB is an automotive-qualified MEMS inertial-sensing module by STMicroelectronics. It provides measurements for a variety of vehicle functions and is provided with dedicated software which addresses functional-safety applications up to ASIL B1.

The module contains a three-axis digital accelerometer and three-axis digital gyroscope and provides a six-channel synchronised output. The inertial measurements can improve the precise positioning of the car in context, said ST. It can support ADAS (advanced driver assistance systems) or vehicle to everything (V2X) communication, help stabilise key sensing systems like radar, lidar and visual cameras, and assist semi-automated driving applications up to L2+. It can also be used to enable a variety of functionalities in the car body, added ST.

Used with the companion software, the ASM330LHB supports automotive systems that require safety integrity up to level B. Using two ASM330LHB sensor modules for fail-safe redundancy delivers resilient contextual data for driver-assistance applications, such as lane centring, emergency braking, cruise assistance and semi-automated driving. The ASIL B -compatible software library has been developed in accordance with the automotive functional-safety standard ISO 26262 and certified independently by TÜV SÜD. The library implements dedicated safety mechanisms, including data integrity and accuracy to ensure compliance with ASIL B automotive systems.

The ASM330LHB has embedded intelligence to add new services about the car status when the driver is away. The integrated machine learning core draws just a few microA of current, said ST and a machine learning algorithm can detect events such as theft attempts, jacking-up or towing, or impacts from other vehicles. 

By monitoring threshold combinations, the integrated finite state machine can detect when the vehicle is in motion or stationary, and for sensing vibrations or instability.

The accelerometer and gyroscope inside the module maintain high stability over time and temperature and have very low noise, achieving an overall bias instability of three degrees per hour. The ASM330LHB operates over the extended temperature range of -40 to +105 degrees C and has multiple operating modes that let designers optimise the data-update rate and power consumption.

The ASM330LHB is AEC-Q100 qualified and in production now in a 2.5 x 3.0mm 14-lead VFLGA package.

GNSS receiver is tailored for automotive applications

Fri, Apr 21, 2023

The u-blox ZED-F9L is an L1/L5 GNSS receiver module, designed for automotive, telematics, V2X (vehicle to everything) and navigation applications.

It has integrated dead reckoning technology, six-axis IMU (inertial measurement unit), multiple outputs and robust automotive grade hardware (AEC-Q104) for  automotive designs that demand top-tier performance and seamless integration, said u-blox.

The ZED-F9L leverages L1/L5 band signals and six satellite constellations simultaneously, including NavIC. The receiver provides continuous sub-meter-level positioning accuracy, using algorithms to combine GNSS measurements, IMU data, wheel ticks, and vehicle dynamics for positioning and attitude data, even when GNSS services are unavailable, u-blox added. The receiver also has a 50Hz output rate with low latency for real-time applications.

Operating temperature is up to 105 degrees C, for use in telematic control units (TCUs) under the roof or smart antennas and motorbike applications. Security features include anti-jamming and sensor-based anti-spoofing techniques.

The ZED-F9L module is pin-to-pin compatible with the ZED-F9K module, offering an upgrade path to RTK (real time kinetic) technology.

u-blox specialises in positioning and wireless communication in automotive, industrial, and consumer markets. The company’s products and services let people, vehicles, and machines determine their precise position and communicate wirelessly over cellular and short range networks. It offers a broad portfolio of chips, modules, and secure data services and connectivity for customers to develop innovative and reliable solutions for the IoT quickly and cost-effectively. The company has headquarters in Thalwil, Switzerland and offices in Europe, Asia, and the USA.

Keysight expands Novus portfolio with compact network test solution for automotive and industrial IoT

Wed, Apr 19, 2023

Keysight Technologies is expanding its Novus portfolio with the Novus mini, a network test platform in a compact form factor that addresses the needs of network engineers as they deploy automotive and industrial internet of things (IoT) devices.

As enterprises transition to Industry 4.0 business models to take advantage of digitalisation, their reliance on connected IoT devices becomes more important to business operations. Industries such as automotive and manufacturing can improve safety and efficiency by connecting IoT machines and sensors to business systems. However, system failures and downtime caused by connectivity and network issues can result in high-risk, life-threatening situations. To mitigate any potential problems, network engineers must fully test the connectivity and performance of network components and IoT devices before deploying them.

Keysight’s Novus mini addresses this need by giving network engineers a compact, quiet, and affordable platform to test the performance and conformance of their industrial networks. The Novus mini supports testing based on time-sensitive networking (TSN) standards, which is a critical safety component in IoT applications such as the advanced driver assistance systems (ADAS) used in autonomous vehicles.

The Novus mini provides network testing value – a combined solution offering both traffic generation and protocol testing in a single platform. It is compact, quiet and affordable. It claims to feature the smallest footprint in the industry, outstanding cost per port, and ultra-quiet, fanless operation. It validates layers 2-3 by covering full performance and conformance testing.

The Novus mini tests critical timing standards for industrial IoT and supports full timing testing and automated time TSN for 802.1AS 2011/2020, 802.1Qbv, 802.1CB and 802.1Qci.

Ram Periakaruppan, vice-president and general manager, Network Test & Security Solutions, Keysight, said that the Novus mini provides real-world validation and automated conformance testing for leading edge technologies. 

As a member of the Avnu Alliance community, Keysight is working with other market leaders to advance Industry 4.0 by crafting essential standards for the next generation of IoT.

Keysight will be at Hannover Messe, 17-21 April 2023, Hall 14, Stand H06.
