STM Launches an Automotive AI Edge for State Classification

Written by Stephen Vicinanza

Just a few days ago, STMicroelectronics launched a new automotive AI Kit on the Edge for car state classification. The AEKD-AICAR1 is based on long-short term memory (LSTM) recurrent neural network (RNN).

The kit provides car state classifications such as a car parked, a car driving on normal road conditions, a car driving on a bumpy road, or the car swerving or skidding. The idea is an innovation that is to define an ECU detection node with embedded artificial intelligence processing.

The AEKD-AICOR1 houses a SPC58EC chorus 4MB microcontroller, which can acquire discrete acceleration variation on a three-axis reference system. The system can represent a reference for the automotive AI on the edge processing.

It is possible to easily replace the sensor with another one that belongs to ST MEMS family. It also offers the ability to modify the neural network and/or retrain the neural network. The new neural system would then be converted into a library that is executable by the MCU using the SPC-STUDI-AI.
