In the distant past, the “eye in the sky” was a radio report on local traffic, especially during rush hour, provided by a reporter/observer and based on their observations from a helicopter or low-flying aircraft. For real-time radio reports, sensing was not necessary. Evolving into TV reporting and planning before departing for work (long before […]

What are the types and uses of position and angle sensors in an EV?
Position and angle sensors are used in several electric vehicle (EV) components, including the traction motor and drivetrain, heating, ventilation, air-conditioning (HVAC) compressor, steer-by-wire, brake-by-wire, regenerative braking, accelerator position, active headlight aiming, active suspension systems, and more. This FAQ reviews some position and angle sensing technologies and how the use cases differ between internal combustion […]
Automotive airflow analysis reveals virtues & limits of sensors, models, and simulations
Design verification requires both sophisticated models and the simulation they offer, as well as real-world validation of their results. Sensors and sensing for real-world physical parameters form a large part of the electronics scene, but it’s easy to confuse the two. A senior project leader I once worked with always reminded us that “sensors are […]
Pressure regulator maximizes hydrogen-powered vehicles fuel efficiency
Emerson has launched the TESCOMTM HV-7000 Series two-stage pressure-reducing regulator, which is designed to maximize fuel efficiency and improve reliability in hydrogen-powered vehicles. Easy to install, HV-7000 Series regulators provide stable pressure delivery, high reliability, and long service life for heavy-duty vehicles powered by fuel cells or hydrogen combustion engines. The HV-7000 features two-stage pressure […]
New stereo vision product for high-accuracy robotics
Teledyne FLIR IIS announced the Bumblebee X series – an advanced stereo vision solution built on our best-in-class stereo vision portfolio. Their legacy of stereo vision solutions started over 25 years ago with Point Grey Research’s Triclops and Digiclops. Now, they have actualized a new industrial stereo camera Bumblebee X, and a software Spinnaker 3D […]
Position-sensing switch for enhanced automotive safety
Melexis has introduced the MLX92442 Induxis switch, which offers a contactless and magnet-free monolithic design to directly detect conductive targets, facilitating small module designs with reduced component count for various applications such as high voltage interlocks, charging flaps, seatbelts, hood/trunk, gear tooth sensing, or brake-by-wire systems. Traditional safety automotive latches and switches typically rely on […]
How current sensing impacts electric vehicles: part 2
Part 1 of this blog addressed current shunts and Hall-effect sensor designs. This part discusses current transformers and new technology options, such as magnetoresistance and diamond quantum sensors. One of the significant issues in today’s electric vehicles (EVs) is the ongoing evolution of technology, with the standards evolving as well. In the 100+ years that […]
How current sensing impacts electric vehicles: part 1
The need to transition from gasoline and diesel (fossil fuels) powered vehicles to electric vehicles (EVs) to reduce carbon dioxide levels has revealed many controversial issues. Common issues include implementation timing, required infrastructure (including fast-charging multi-vehicle systems), legislated rather than consumer-based adoption, ongoing system enhancements, and new critical raw materials sources. Current sensing technology is […]
3MP SoC image sensor for LED flicker-free, high dynamic range automotive cameras
OMNIVISION debuted the first OX03J10 3-megapixel (MP) CMOS system-on-chip (SoC) image sensor with 140dB high dynamic range (HDR) and LED flicker mitigation (LFM) for superior image quality regardless of lighting condition. The OX03J10 SoC is ideal for surround-view systems (SVS), rear-view cameras (RVC), and camera-monitoring systems (CMS). By integrating the image sensor with a dedicated image signal processor (ISP) […]
mmWave radar sensor chip and diagnostics-integrated driver chips address functional safety
Texas Instruments has introduced new semiconductors designed to improve automotive safety and intelligence. The AWR2544 77GHz millimeter-wave radar sensor chip is the industry’s first for satellite radar architectures, enabling higher levels of autonomy by improving sensor fusion and decision-making in ADAS. TI’s new software-programmable driver chips, the DRV3946-Q1 integrated contactor driver and DRV3901-Q1 integrated squib […]
