ADAS & Autonomous Vehicle Engineering - January 2023 - 21

New Tools & Technologies
Pedestrian target
Messering (Ingolstadt, Germany) released its articulated pedestrian
adult target, which replicates a 50% male adult in terms of size, shape,
realistic sensor signature and leg articulation. The target complies with
all specifications of the NCAP and ACEA guidelines as well as the ISO
19206-2 standard. Messering states that the target was developed to
meet the exact requirements and test protocols for active safety tests
such as lane-assist and AEB. The sensor signature reportedly can be
reproduced for radar, lidar, camera, infrared and ultrasonic sensors
simultaneously. The target is designed for collisions up to 60 km/h (37
mph) and activation of the leg motion is controlled via an IP-based
interface and offers a selection of walking speeds.

Collision-avoidance sensors
Toposens (Munich, Germany) unveiled its 3D collision-avoidance
system for mobile robots. The system
is intended for use with automated forklifts,
AMRs and AGVs. According to the company, the
system uses sound-based triangulation in combination
with noise-filtering software to deliver 3D
data output for each obstacle detected within the fully adjustable warning and stop
zones. Zones can be set to dynamically follow a mobile robot taking a left or right
turns and adjust to the speed of the vehicle. The sensor sends the obtained data
(echo reflections perceived by three microphones) in a 3D point-cloud format to the
processing unit, which is equipped with 3D collision-avoidance software.

Oscillators
SiTime Corporation (Santa Clara, California), introduced
their new automotive oscillator family, based
on SiTime's MEMS technology. The new differential
oscillators are reportedly much more resilient and
ensure reliable operation of ADAS across extreme
road conditions and temperatures. The oscillators
feature an operational temperature range of -40°
to 125° C (-40° to 257° F). The new oscillators also
reportedly feature reduced vibration sensitivity and flexible programmable features
from 1 MHz to 920 MHz and 1.8 V to 3.63 V. Differential output drivers include
LVPECL, LVDS, HCSL and low-power HCSL and FlexSwing, giving developers a wide
range of output options for their system designs.

Camera PMICs
Renesas (Tokyo, Japan) unveiled its
power management IC (PMIC) for
next-generation automotive camera
applications. The RAA271082 is a versatile
ISO-26262 compliant multi-rail
power IC with a primary high-voltage
synchronous buck regulator, two secondary
low-voltage synchronous buck
regulators, and a low voltage LDO regulator.
It offers four overvoltage and
undervoltage (OV/UV) monitors, I2C
communications, a configurable general-purpose
I/O pin and a dedicated
reset output/fault indicator. To meet
stringent ASIL B metrics, the
RAA271082 includes a second independent
reference for OV/UV monitors,
built-in self-test at power-up, independent
OV/UV monitoring and continuous
CRC error checking on internal registers
and I2C communications.
