hile marquee automakers and suppliers ditched CES 2022
due to a COVID surge, more than a dozen lidar suppliers
unveiled their latest products and innovations during the
show. The following is a highlight of sensor companies'
CES announcements and how they fit into the ever-changing automated/autonomous-vehicle
(AV) and mobility landscape.
Blickfeld
This German startup called its Qb2 sensor unveiled at CES " the next
generation of lidar " due to capturing and processing of 3D data being
performed by a single-unit integrated system and requiring no
additional compute, servers, or adaptor boxes - a world first, the
company said. The device combines MEMS (microelectromechanical
systems) hardware with a compute module that runs Blickfield's
Percept software stack, which the company also announced at CES.
Beyond AV and mobility applications, Percept software can be used
for crowd analytics, traffic management, smart industry and security
solutions, with the Frankfurt, Germany, airport already deploying the
software in a people-counting application.
Hesai Technology
This Chinese supplier showed its new AT128 lidar sensor at CES, a
directional long-range hybrid solid-state solution designed for ADAS
applications in mass-production vehicles. Hesai said the AT128 provides
consistent resolution over a full field of view and has a small
form factor for easy integration onto production passenger and commercial
vehicles. The AT128 provides an ultra-high measurement freAUTOMOTIVE

quency of over 1.53 million points per second (single
return) and range of more than 200 meters (656 feet)
with 10% reflectivity and effective object detection as
far as almost 70 meters (230 feet). Hesai said the
AT128 has been subjected to more than 50 validation
tests conducted according to OEM standards such as
electrical, mechanical, environmental, sealing, material
and EMC tests.
The company said the AT128 is developed based on
Hesai's proprietary lidar application-specific integrated
circuits (ASICs), which it said greatly simplify the assembly
process and increases manufacturing efficiency
and consistency for mass production. Hesai's AT128 has
secured contracts for multiple ADAS programs, mainly
from Chinese mobility companies, including Li Auto,
HiPhi and JiDU, an electric vehicle venture between
China tech giant Baidu and Chinese automaker Geely.
Hesai said the contracts call for several million units and
that the sensor begins mass production in 2022.
Innoviz
This Israeli company is considered one of the leaders in
automotive lidar and was one of the first to develop lidar
that uses a MEMS-based sensor. Its first volume commercial
sensor, the InnovizOne, is scheduled to launch on
BMW vehicles later this year and includes four lasers,
detectors and MEMS units. Innoviz also debuted a pair of
