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

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.

STMicroelectronics adds Zigbee 3.0 support for wireless microcontrollers

Based on Zigbee PRO protocol stacks, Zigbee 3.0 has been added to the STM32WB55 wireless microcontrollers. The company says that STM32 developers can leverage the interoperability and power-saving features of Zigbee to enhance networking for projects such as home automation, smart lighting, smart building, and broader IoT connectivity.

Zigbee 3.0 unifies the features of Zigbee specifications for consumer and industrial applications. Consumer and internet brands have elected to choose Zigbee connectivity for smart home products.

ST’s Zigbee 3.0 software for STM32WB55 includes the Exegin Zigbee PRO protocol stack, which is provided free of charge, and delivered and fully supported by ST. The stack is used in Exegin products certified as Zigbee Golden Units and is approved as a reference stack for use by test laboratories. ST supports 46 Zigbee 3.0 clusters to establish the capabilities of devices. Another21 clusters support legacy products.

STM32WB55 microcontrollers also support Thread and Bluetooth 5.0, with over the air (OTA) update capability. There are 10 STM32WB55 variants, in a choice of package styles and flash density from 256kbyte to 1Mbyte. The company has announced that it will introduce further variants in Q3.

Devices feature the Arm Cortex-M4 with floating point unit, DSP instructions and a memory protection unit (MPU) that enhances application security. Arm Cortex-M0+ co-processor is dedicated to managing the integrated IEEE 805.15.4 radio. The microcontroller’s cyber protection features ensures real time, low layer operations run smoothly without compromising application execution. The RF transceiver has a link budget of 106dB, to ensure reliable connections over distance.

The STM32WB55 devices are based on patented low power microcontroller technologies and integrate features such as radio balun circuitry. These characteristics are designed to help designers meet tight power and size constraints in a range of IoT and wearable devices. There are rich analogue and system peripherals, as well as cyber-protection, adds ST, and ID features including secure firmware installation (SFI), customer key storage, hardware public key authority (PKA), and cryptographic accelerators. Capacitive touch and LCD controllers simplify user-interface integration.

The Zigbee 3.0 software is now included in the STM32CubeWB MCU package, which provides embedded software including low-layer (LL) application programming interfaces (APIs) and hardware abstraction layer (HAL) drivers for STM32WB microcontrollers, as well as Bluetooth 5.0, Mesh V1.0, and Thread libraries, FreeRTOS kernel, FatFS file system and the STMTouch capacitive-sensing library.

The STM32Cube ecosystem includes the STM32CubeMonitor-RF for RF testing and STM32CubeMX for device configuration and code generation.

Toshiba eliminates mechanical components from solid state lidar

Autonomous vehicles increasing rely on lidar systems but the mechanical components in lidar systems can add cost and occupy valuable space. Toshiba has developed a high resolution, long range light receiving technology for use in solid state lidar systems which does not rely on mechanical components and which is compact, low-cost and simple to install, says the company.

The technology is based on Toshiba’s proprietary compact, high-efficiency silicon photo-multiplier (SiPM). The company says that by removing the need for bulky mechanical components, the technology realises cost and space savings and enhances operational reliability.

In general, SiPM are suitable for long range measurement as they are highly light sensitive. SiPM’s light-receiving cells however, require recovery time after being triggered, and in strong ambient light condition they also need a large number of cells, as reserve cells are needed to react to reflected laser light.

Toshiba’s SiPM applies a transistor circuit that reboots the cells to reduce the recovery time. The cells function more efficiently and fewer are needed. The higher resolution SiPM array maintains high sensitivity, reports Toshiba.

Conventional lidar systems require mechanical components to continuously rotate the laser emitters and their accompanying optical detection devices. Field trials show that the solid state lidar, using commercially available lenses, from wide-angle to telephoto lenses, have demonstrated the system’s effectiveness over a maximum distance of 200m. This range effectively quadruples the capabilities of currently available solid state lidar systems without sacrificing high resolution, says the company.

Toshiba’s lidar system can be built with commercial lenses, which eliminates complex customisation, for application in a variety of self driving vehicles. The compact nature of the technology allows it to be placed in multiple locations on vehicles that had previously presented a major challenge and will also broaden the appeal and feasibility of lidar outside of the automotive sector.

Toshiba says it will continue R&D to further extend lidar measuring range, raise resolution and advance miniaturisation, and is aiming for a practical use of the SiPM to be available in 2022.
