January 8, 2019
-
Only automotive-qualified inertial measurement unit (IMU) that is
fully compatible (pin, package, register, and software) with a 3-axis
automotive accelerometer, and a 3-axis automotive gyroscope -
Smallest 6-axis automotive-qualified device with high-rate, 100 Hz
position updates supplied to autonomous vehicle (AV) systems - Automotive-qualified IMU capable of 105°C
LAS VEGAS–(BUSINESS WIRE)–TDK Corporation (TSE:6762) announces today the availability of a new
line of automotive high-accuracy devices from InvenSense, a TDK group
company.
-
IAM-20680: With operating range of -40°C to 85°C, the smallest
6-axis automotive-qualified sensor is the industry’s only device
featuring 16-bit accelerometers and 16-bit gyroscopes in a series
production car today -
IAM-20680HP: High-performance version of the IAM-20680 with an
operating range of -40°C to 105°C, high gyroscope and offset
thermal stability, as well as pin, package, and register
compatible with the IAM-20680 -
IAM-20380: With operating range of -40°C to 85°C, the only
automotive-qualified gyroscope fully compatible (pin, package,
register, and software) with a 3-axis automotive accelerometer
(IAM-20381) and an automotive-qualified 6-axis device (IAM-20680) -
IAM-20381: With operating range of -40°C to 85°C, the only
automotive-qualified 3-axis accelerometer fully compatible (pin,
package, register, and software) with a 3-axis automotive gyroscope
(IAM-20380) and an automotive-qualified 6-axis device (IAM-20680)
TDK’s family of automotive solutions can help enhance the absolute
position of a vehicle in GNSS- and GPS-denied environments, such as
tunnels, parking garages, and urban canyons. A vehicle’s navigation
system can use the output of the 6-axis automotive-qualified IAM-20680HP
or of the IAM-20680 to improve estimate of the position, direction, and
speed of a vehicle when the satellite signal is deteriorated or
non-existent as well as to improve the quality of the position
estimation when the satellite signal is strong. The product family
measures up to 16g acceleration and up to 2000dps (degrees per second).
The low noise helps the car navigate in a straight line while low
sensitivity error keeps the car turning correctly. The solutions
superior temperature stability also enables navigational driving through
the most challenging environments.
The extreme flexibility of the family of TDK automotive sensors allows
customers to design with the IAM-20680; or, if navigating in very high
temperature environments and for systems where cooling is weak or not
available, the IAM-20680HP may be used. If cost efficiency is the most
important consideration, the IAM-20380 or IAM-20381 is the suitable
choice. TDK’s new family of automotive-qualified sensors can be
interchanged without the need to redesign hardware or software.
“With the increased usage of location services for turn-by-turn
navigation, the importance of not losing your GPS or GNSS signal due to
environments like tunnels, parking garages, and urban canyons is
paramount,” said Amir Panush, Vice President and General Manager, Motion
and Pressure Business Unit at TDK. “With a full family of InvenSense
product offerings that are automotive qualified, OEMs have a plethora of
options to differentiate the user experience and supply consumers with
more reliable navigation solutions.”
The IAM-20680
and IAM-20680HP are also designed into the new InvenSense Coursa
Drive software solution, the world’s first inertial-aided positioning
software solution for autonomous vehicle platform developers. Coursa
Drive enhances inertial-only vehicle positioning to <0.2% of distance
traveled, such levels are critical to maintaining decimeter lane-level
vehicle positioning in challenging environments and delivers a
cost-effective, vehicle-dead-reckoning accuracy software solution
equivalent to high-end systems costing tens of thousands of dollars.
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 TDK automotive sensor solutions, along with
additional innovative sensor solutions in Booth #30306, Las Vegas
Convention Center, South Hall 3, January 8-11, Las Vegas, Nev. For
