TDK Corporation has introduced a new line of automotive high-accuracy devices from InvenSense, a TDK group company. The line includes the IAM-20680, IAM-20680HP, IAM-20380 and IAM-20381.

According to the company, its family of automotive solutions can help enhance the absolute position of a vehicle in GNSS- and GPS-denied environments. They also can be interchanged without the need to redesign hardware or software.

The IAM-20680 is a 6-axis qualified sensor that features 16-bit accelerometers and 16-bit gyroscopes. The IAM-20680HP is a high-performance version of the IAM-20680 that features high gyroscope and offset thermal stability. The IAM-20380 is an automotive-qualified gyroscope fully compatible with a 3-axis automotive accelerometer and an automotive-qualified 6-axis device. The IAM-20381 is an automotive-qualified 3-axis accelerometer fully compatible with a 3-axis automotive gyroscope and an automotive-qualified 6-axis device.

The IAM-20680HP and IAM-20680 can be used to improve estimates 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 company said. Customers can design with the IAM-20680 and can use the IAM-20680HP when navigating in high temperature environments or for systems where cooling is weak or unavailable.

If cost efficiency is an important consideration, the company recommends the IAM-20380 or IAM-20381.

“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 of the 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, an inertial-aided positioning software solution for autonomous vehicle platform developers.
