Cohda and u-blox partner for V2X to progress vehicle safety

Fri, Jul 10, 2020

Partners u-blox and Cohda Wireless have announced a vehicle to everything (V2X) solution based on the former’s UBX-P3 DSRC/802.11p V2X chip and the latter’s V2X software stack.

The u-blox UBX-P3 chip enables wireless vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication. It has now been enhanced with Cohda’s hardware-agnostic software applications, providing 360 degree awareness and detecting hidden threats beyond anything a driver or on-board sensors can see, says Cohda. Its V2X software is used in GM and VW production vehicles.

The partnership is expected to be of interest to tier ones, OEMs and road authority suppliers.

According to Cohda’s chief engineer, Fabien Cure, to progress vehicle safety, OEMs need to produce vehicles that have embedded V2X wireless communication technology as standard. “Likewise, cities around the world are preparing for the introduction of wide scale co-operative intelligent transport systems,” he said.

Porting Cohda’s V2X software stack onto the UBX-P3 chip enables a swift integration into automotive platforms, said Herbert Blaser, senior director, Product Center Short Range Radio at u-blox.

Cohda’s software products are applied in more than 60 per cent of all V2X field trials in the world today in compliance with US Federal Communications Commission and European Telecommunications Standards Institute (ETSI) standards.

“When we connect vehicles to each other and to roadside infrastructure, we are creating an intelligent and integrated road transport system that has the potential to reduce road accidents simply because the technology is capable of things humans aren’t,” added Cure.     

u‑blox provides positioning and wireless communication in automotive, industrial, and consumer markets to allow people, vehicles and machines determine their precise position and communicate wirelessly over cellular and short range networks. The company has a broad portfolio of chips, modules and secure data services and connectivity.

Cohda Wireless develops connected vehicles and connected autonomous vehicle software. Its technology connects vehicles with infrastructure and pedestrians to make streets, cities and working environments safer, smarter and greener.

Its software enables autonomous vehicles to connect with other vehicles and with smart city infrastructure, from vehicle-to-vehicle, vehicle-to-infrastructure and vehicle-to-pedestrian to avoid accidents, reduce congestion and be more efficient.

Cohda is headquartered in Australia and has offices in Europe, China and the USA.

GPU IP advances ADAS with safety-critical graphics, says Imagination

Fri, Jul 10, 2020

Claimed to be the most advanced automotive GPU IP created to date and the industry’s first licensable IP that is ISO 26262-capable, XS has been announced by Imagination Technologies.

The XS GPU for automotive will enable ADAS acceleration and – being ISO 26262-capable – safety-critical graphics workloads, says the company.

Safety critical graphics and compute capabilities are required for surround view, digital dashboards and ADAS. The XS design employs a new safety architecture with mechanisms for compute and graphics delivering up to two times higher performance for critical workloads. The result is rich, high-performance graphics that are functionally safe, says Imagination.

According to the company, the XS class is the industry’s first GPU class designed for safety-critical graphics applications (i.e., where the GPU is responsible for critical tasks such as digital dashboards, surround view and camera systems).

As the industry’s first ISO 26262-capable GPU IP, OEMs, Tier 1s and semiconductor vendors can integrate the IP confident that ISO 26262 is achieved, adds Imagination.

The safety architecture contains patent pending technology that enables Imagination to secure and verify the correct execution and delivery of data from the GPU to meet functional safety requirements. XS includes hardware mechanisms that carry out safety-critical workloads across compute and graphics.

 The architecture incorporates new capabilities and safety mechanisms, such as Tile Region Protection, in addition to existing features such as virtualisation. These hardware features mean they can be employed without a performance penalty.

This a significant step forward for automotive GPUs and autonomous vehicles.”

Imagination supplies GPUs for automotive SoCs for use in digital dashboards, surround view and infotainment systems. The UK-based company creates silicon and software IP based on graphics, compute, vision and AI and connectivity technologies.

In 2017, Imagination Technologies was acquired by Canyon Bridge, a global private equity investment fund.

Wafer level automotive camera module boasts lowest power consumption

Mon, Jun 15, 2020

For driver monitoring systems in vehicles, OmniVision offers what is claimed to be the first automotive wafer level camera module. The reflowable OVM9284 CameraCubeChip is a 1Mpixel module which measures 6.5 x 6.5mm. It is claimed to provide maximum flexibility regarding placement within the cabin while remaining hidden from view. It also has, says OmniVision, the lowest power consumption among automotive camera modules; over 50 per cent lower than the nearest competitor.

The OVM9284 is built on OmniVision’s OmniPixel 3-GS global-shutter pixel architecture, which provides best quantum efficiency at the 940nm wavelength for high quality driver images in near or total darkness. The integrated OmniVision image sensor has a three micron pixel and a ¼ inch optical format, along with

1280 x 800 resolution.

Driver monitoring systems (DMS) is expected to be the next growth area for ADAS cameras to address driver distraction.

“Most existing DMS cameras use glass lenses, which are large and difficult to hide from drivers to avoid distraction, and are too expensive for most car models,” said Aaron Chiang, marketing director at OmniVision. “Our OVM9284 CameraCubeChip module is the world’s first to provide automotive designers with the small size, low power consumption and reflowable form factor of wafer-level optics,” he added.

The OVM9284’s integration of OmniVision’s image sensor, signal processor and wafer-level optics in a single compact package reduces the complexity of dealing with multiple vendors, and increases supply reliability while speeding development time. Furthermore, unlike traditional cameras, CameraCubeChip modules are reflowable. This means they can be mounted to a PCB simultaneously with other components using automated surface mount assembly equipment, which increases quality while reducing assembly costs.

OVM9284 module samples are available now, and mass production is expected in Q4 of 2020.

OmniVision Technologies develops digital imaging based on its award-winning CMOS imaging technology for consumer and commercial applications, including mobile phones, security and surveillance, automotive, tablets, notebooks, webcams and entertainment devices, medical and AR, VR, drones and robotics imaging systems.
