January 8, 2019
-
Inertial-only decimeter-precise positions provided during short GNSS
or perception system outages/uncertainties -
High-rate, 100 Hz position and orientation updates supplied to the
autonomous vehicle (AV) system -
GNSS-agnostic software solution offers flexible integration for
full-stack AV solution providers -
Offline mode enhances accuracy for High Definition (HD) map building
and maintenance applications -
Coursa Drive is being integrated with key AV platform partners for
demonstration to OEMs in Q1 2019
LAS VEGAS–(BUSINESS WIRE)–TDK Corporation (TSE:6762) announces today the launch of InvenSense
Coursa Drive software, the world’s first inertial-aided positioning
solution for AV platform developers. A high-performance extension of the
InvenSense Positioning Library (IPL) that has provided sensor-aided
positioning to over 50 million devices worldwide, Coursa Drive enhances
inertial-only vehicle positioning to <0.2% of distance traveled. These
precise levels of accuracy are critical to maintaining decimeter
lane-level vehicle positioning in challenging GNSS/perception system
environments.
Coursa Drive’s inertial navigation system (INS) calibrates using
absolute position inputs from either high accuracy GNSS receivers or
from perception-based systems (camera, radar, lidar) with HD maps. In
real time, Coursa Drive provides high-rate, 100 Hz delta positions and
orientation to the AV system, complementing the lower-rate position
references from GNSS and perception systems. For improved system
fault-tolerance, Coursa Drive can provide decimeter position precision
for short periods when the GNSS or perception systems are uncertain or
unavailable.
For non-real-time applications such as HD map creation and maintenance,
Coursa Drive’s offline mode reprocesses INS data at two to three times
higher accuracy than real-time mode, providing HD map companies
alternative position references to verify HD map accuracy, even without
GNSS, for up to 60 seconds.
“Coursa Drive delivers vehicle dead reckoning accuracy equivalent to
high-end systems costing thousands of dollars,” said Mike Housholder,
Senior Director of the TDK InvenSense Location Software and Services
Business. “Our cost-effective software solution will help AV platform
and Tier 1 vehicle manufacturers scale beyond prototype vehicles to
high-volume mass production.”
Coursa Drive provides AV platform developers with maximum flexibility
for system integration. The solution is platform agnostic and can
operate on Cortex-M4F-class microcontrollers, or higher, and supports
most dual-frequency GNSS receivers. The Coursa Drive API specifications
are available upon request.
Coursa Drive is thoroughly tested and characterized using the InvenSense
line of automotive-grade IMUs, including the IAM-20680
and IAM-20680HP, as well as several industrial grade IMUs. Coursa
Drive is available now for select early partners and customers.
TDK and its group companies offering a comprehensive portfolio of
sensors, electronic components and solutions for mobile, wearables,
AR/VR, automotive, IoT and industrial applications will be at CES
2019, showcasing the Coursa Drive solution, along with additional
innovative sensor solutions, in Booth #30306, Las Vegas Convention
Center, South Hall 3, January 8-11, Las Vegas, Nev. For additional
