POLYN Neuromorphic Tire Monitoring Evaluation Kit

POLYN has recently made a significant announcement by releasing the VibroSense Tire Monitoring Evaluation Kit for general availability. This evaluation kit is designed to assist automotive, ADAS, and tire vendors in initiating the integration and design processes for intelligent tire monitoring systems even before the commencement of product manufacturing.

The VibroSense-TMS is a groundbreaking neuromorphic chip that is capable of processing tire vibration data to detect real-time changes in tire-road friction. By extracting crucial information for driving safety from within the tire using only microwatts of power, this tire monitoring technology enables the instant transmission of friction change alerts to the vehicle’s ADAS.

One of the key features of the VibroSense TMS is its provision of always-on, continuous friction monitoring. This functionality allows vehicles to adjust braking, traction control, and autopilot systems more precisely to all driving conditions, ultimately enhancing overall safety on the road.

Within the Tire Monitoring Evaluation Kit, users will find a standard TPMS sensor node for data collection and a Neuromorphic Analog Signal Processing (NASP) model for monitoring friction. Additionally, an SDK is included to facilitate the flexible calibration of the model for different types of tires. The kit operates with a live tire vibration signal, enabling the neural cores to be tested in real-time under various road conditions.

The Data Acquisition Unit (DAU) within the kit is equipped with an Infineon SP-49 sensor SoC and BLE for data transmission to a dedicated tablet (PAD) unit. This PAD unit provides live visualization of the peak friction coefficient (PFC) estimation and displays real-time PFC monitoring for two tires, such as the front left and right tires.

According to Aleksandr Timofeev, the CEO of POLYN, “VibroSense transforms existing TPMS into real-time tire-road friction monitors, enabling next-generation tire intelligence and seamless integration with ADAS braking technology. The challenge of transmitting vibration data from tires to the vehicle is addressed by our ultra-low-power neuromorphic processing solution. VibroSense extracts the PFC values directly within the tire and communicates with the vehicle’s ADAS only in the event of friction changes.”

Timofeev further added, “The intelligence embedded in the VibroSense Tire Monitoring Solution Evaluation Kit is derived from the real-world collection of PFC labeled data, obtained from various cars, tires, and surfaces, covering ten PFC levels of road friction ranging from 0.1 to 0.9. Vendors from different industries related to automotive are encouraged to evaluate this innovative solution.” POLYN NASP stands out by providing cloudless AI on IoT devices, supporting sustainability and enabling the deployment of Edge AI computing across real-world IoT applications like connected cars, industrial IoT, wearables, and consumer electronics.
