Tech Focus: Looking Ahead – High Speed In-Vehicle Display and Sensor Connections (Part 2 of 2)

Friday, December 17th, 2021

In this two-part guest commentary, Carrie Browen and Kevin Kershner from Keysight Technologies share their insights into the future of high speed in-vehicle display and sensor connections. You may find Part 1 here.

For this second half of our commentary, we begin with an introduction of SerDes.

In today’s infotainment systems, it is common for in-vehicle cameras and displays to be connected to the image-processing electronic control unit (ECU) via a SerDes (serializer/deserializer) connection.

Today, they are delivered by individual vendors using closed, proprietary standards.

Extending the reach of feature-rich SerDes links can require operating at lower Baud rates and higher order modulations (e.g. PAM-4).

In addition, it will require higher bandwidth Ethernet links as primary interconnects between zones, perhaps with 802.3ch support up to 10 Gbps throughput.

Emerging SerDes standards like mobile industry processor interface (MIPI) A-PHY (MIPI A-PHY is a physical layer specification targeted for ADAS/ADS surround sensor applications and Infotainment display applications in automotive) and Automotive SerDes Alliance (ASA) will be implemented by multiple silicon vendors.

This will create a competitive market that acts to drive down the cost while delivering application specific features.

Tech Focus: C-V2X Certification – Necessary or Just Nice to Have?

Monday, November 22nd, 2021

Fewer accidents and greater road safety are central to the vision for automated vehicles (AVs). Enabling that vision requires greater situational awareness and the ability to inform the car and its drivers what is happening a mile in front of them, foreseeing what’s likely to happen next, and automatically taking preemptive actions.

In this guest commentary, Cheryl Ajluni from Keysight Technologies shares her insights into C-V2X certification.

Cellular vehicle-to-everything (C-V2X) technology provides see-through, 360-degree, non-line-of-sight (NLOS) sensing in good, as well as adverse weather conditions to enhance the functionality and safety of autonomous driving (see the cover illustration).

C-V2X complements line-of-sight (LOS) sensors such as radar, lidar, camera, with information beyond their reach, and allows the vehicle to make more informed and coordinated decisions.

Whereas LOS sensors cannot indicate vehicle or driver intent, C-V2X conveys intent by sharing sensor data – resulting in a higher level of predictability in traffic situations such as lane changes, variable speeds, or road hazards.

Day one use cases include safety features such as emergency electronic brake light and forward collision warning, ‘do not pass’ warning, blind spot and lane change warning, vulnerable road user, road works warning, and intersection movement assistance.

Tech Focus: The Electric Vehicle Race to Market

Friday, October 29th, 2021

Three rapidly advancing technologies are driving this collective race towards zero-emission e-mobility: wide-bandgap (WBG) devices, more power-dense batteries, and faster charging capabilities.

In this guest commentary, Hwee Yng Yeo from Keysight Technologies shares her insights into the great EV race.

Since its inception on a paper napkin more than a decade ago, Formula E has evolved rapidly as a motorsport with a mission.

Entertainment aside, this electric streetcar racing’s founding mission is to showcase sustainable mobility to the world, and it has done pretty well.

It’s the only motorsport to have ISO 20121 certification for net zero carbon footprint since its first race in Shanghai in 2014.

Getting the Formula E car into pole-position entails a lot of hardware and software technology to extract maximum efficiency from the electric vehicle’s (EV) powertrain and battery.

For the key automotive OEMs, it’s not just about getting their car across the checkered flag first.

With billions of R&D dollars poured into developing better EVs, the goal of participating automakers goes beyond the championship trophy.

Learnings from these high-intensity races are applied to improve electromobility technologies back in the R&D labs.

Three rapidly advancing technologies are driving this collective race towards zero-emission e-mobility:

  1. wide-bandgap (WBG) devices
  2. more power-dense batteries
  3. faster charging capabilities

Efficient power conversion with WBG devices

A lot of power conversion takes place in the EV.

A DC-DC converter for example, steps down the power from the high-voltage EV battery to 12 V, with further conversions to run onboard systems like lighting, radio, and air-conditioning (see the diagram above).

The author of this article is Hwee Yng Yeo, the industry solutions manager for Automotive and Energy at Keysight Technologies.

WBG devices such as Silicon carbide (SiC) and Gallium nitride (GaN) semiconductors are used in transistors to facilitate this power conversion throughout the vehicle.

GaN applications are an emerging technology area, and developers find it hard to validate their design for these high-performance power converters.

Increased frequency and higher power affect the reliability of measurements needed to characterise the device’s performance.

It can be hard to distinguish whether the measured signal is the device’s characteristic or caused by the measurement setup.
