ST introduces AI-enabled automotive inertial measurement unit for always-aware applications up to 125°C

Tue, Dec 05, 2023

ST’s ASM330LHHXG1 inertial measurement unit (IMU) for automotive applications combines in-sensor AI with enhanced low-power operation and 125°C operating temperature range for reliability in harsh environments.

ST’s new automotive IMU contains a 3-axis accelerometer and 3-axis gyroscope and draws less than 800µA with both sensors running, cutting the system power budget and encouraging use in always-aware applications. In-sensor AI leverages the built-in machine-learning core (MLC) and finite state machine (FSM), offloading the host processor and enabling low-latency, energy-efficient event detection and classification. The extended temperature range gives flexibility to deploy smart sensors containing the ASM330LHHXG1 in harsh locations including near engine components, in direct sunlight, or whenever on-board power dissipation might increase the temperature above standard operating levels.

With the integrated MLC and FSM, the ASM330LHHXG1 handles applications that need fast and deterministic response with minimal power demand. These include navigation assistance and telematics, theft prevention, impact detection, and motion-activated functions.

ST’s MEMS ecosystem helps accelerate evaluation, prototyping and development with the ASM330LHHXG1, leveraging Unico-GUI and AlgoBuilder tools and MEMS-sensor adapter boards (STEVAL-MKI243A). Also, engineers can find ready-to-use application examples at ST’s GitHub repository area. The MLC repository contains use cases such as tilt, towing, and vehicle-status detection. The FSM repository has further inspiration including motion/stationary detection and shake detection.

While the IMU has dual operating modes that let designers optimise the data-update rate and power consumption, the accelerometer and gyroscope maintain high stability over time and temperature. The accelerometer has a selectable full-scale range of ±2/±4/±8/±16g, while the gyroscope’s angular rate can be set to ±125, ±250, ±500, ±1000, ±2000, or ±4000 degrees per second.

The ASM330LHHXG1 is AEC-Q100 qualified and in production now. It is available in an over-molded 14-lead plastic land grid array (LGA) package.

Experience the most complete In-Cabin Monitoring Solution at CES

Mon, Dec 04, 2023

Melexis and emotion3D are launching a revolutionary automotive in-cabin monitoring solution based on 3D time-of-flight technology (ToF). It overcomes limitations of established driver monitoring systems (DMS).

Legislative momentum for advanced driver distraction warning (ADDW) is growing worldwide. Driver Monitoring Systems (DMS) strive to detect driver inattentiveness, fatigue, and distraction. Occupant Monitoring Systems (OMS) aim to provide occupant detection, classification and body tracking to enhance passive safety through smart restraint control (RCS) & dynamic automatic suppression systems (DASS). 3D ToF technology uniquely offers the best performance to merge both DMS & OMS applications into a single camera solution.

3D ToF cameras utilising Melexis’ automotive-qualified MLX75027, true VGA ToF sensor, and emotion3D’s CABIN EYE software simultaneously generate IR and distance images, thereby mapping a full scene in three dimensions. This essential information is used to accurately assess driver fitness to drive, whilst indicating the location of other occupants in the vehicle, detect limb position, track movements and body or hand gestures. Direct access to measured distance data greatly improves image segmentation options, reduces the computational load and thus lowers system cost.

“The combination of Melexis’ automotive track record in 3D sensing with easily accessible application software from emotion3D helps customers to overcome the challenges to create improved safety systems ”, says Kristof Lieben, Product Manager at Melexis. “Overall, this joint offering significantly simplifies and accelerates the development of camera monitoring systems. It enables competitively priced solutions that will enhance safety for everyone on the road and can increase comfort & convenience for its users.”

“This Driver & Occupant Monitoring System (DOMS) solution in partnership with Melexis showcases the latest technology in the field to combine three important concerns in the in-cabin environment: active safety, passive safety and user experience” said Florian Seitner, CEO of emotion3D. “We hope to welcome many visitors from the automotive industry to come see the demonstrator in action at CES this January.”

Rohm’s new high power 120w laser diode for LiDAR

Fri, Dec 01, 2023

Rohm has developed a high-power laser diode – the RLD90QZW8. It is ideal for industrial equipment and consumer applications requiring distance measurement and spatial recognition.

In recent years, LiDAR is being increasingly adopted in a wide range of applications that require automation – including AGVs (Automated Guided Vehicles), robot vacuums, and autonomous vehicles – where it is necessary to accurately measure distance and recognise space. In this context, there is a need to improve the performance and output of laser diodes when used as light sources to increase detection distance and accuracy.

To meet this demand, Rohm established original patented technology to achieve a narrower emission width that contributes to longer range and higher accuracy in LiDAR applications. In 2019, Rohm released the 25W laser diode RLD90QZW5 followed by the 75W laser diode RLD90QZW3 in 2021. In response to the growing market demand for even higher output, Rohm developed the new 120W laser diode.

The RLD90QZW8 is a 120W infrared high output laser diode developed for LiDAR used in distance measurement and spatial recognition in 3D ToF systems. Original device development technology allows Rohm to reduce the temperature dependence of the laser wavelength by 66% over general products, to just Δ11.6nm (Ave. 0.10nm/°C). This makes it possible to narrow the bandpass filter while extending the detection range of LiDAR. At the same time, a uniform light intensity of 97% is achieved over the industry’s smallest class* of emission width of 270µm, representing a range of 264µm that contributes to higher resolution. Additional features that include high power-to-light conversion efficiency (PCE) enables efficient optical output that contributes to lower power consumption in LiDAR applications.

A variety of design support materials necessary for integrating and evaluating the new product is available free of charge on Rohm’s website that facilitate market introduction. In order to drive laser diodes with high nano-second order speed required for LiDAR applications, ROHM developed a reference design available now that combines ROHM’s 150V EcoGaN™ HEMT and gate drivers.

Rohm has also acquired certification under the IATF 16949 automotive quality management standard for both front-end and back-end processes at its manufacturing facilities. As a result, product development of laser diodes for automotive applications (AEC-Q102 compliant) is underway, with commercialisation planned by the end of 2024.
