The tire pressure monitoring system boosts road safety and vehicle efficiency and extends battery life with innovative sensor technology.
TREEL Mobility Solutions, a provider of automotive technologies, focuses on enhancing road safety and boosting efficiency in vehicles, tires, and fuel through its ‘Tire Pressure Monitoring Solution’ (TPMS). This system handles different pressure levels, excessive vibration, and temperature fluctuations. It’s suitable for a wide range of vehicles, including two- and four-wheel vehicles, buses, and both light and heavy commercial vehicles, as well as for off-road use. After over four years of production, the system has evolved to align with the market for tire monitoring.
The TPMS is offered in three models. The first variant consists of sensors fitted to each tire, including the spare, to monitor pressure and temperature. Each sensor utilizes the Nordic Semiconductor nRF52810 SoC, powered by an Arm® Cortex™-M4 processor, to oversee the system.
The second variant integrates these sensors with a Bluetooth device acting as a central and peripheral unit. It features a multiprotocol radio that sends data to an nRF52832 SoC via Bluetooth® LE. This SoC then relays the tire pressure and temperature data directly to the vehicle’s Controller Area Network (CAN) or a mobile app for user notification.
The third variant includes the sensors and a ‘TREEL Mobility Solutions TPMS Receiver’. This receiver uses the nRF52833 SoC to gather data and displays tire status through a separate screen unit.
The ‘Smart Tire’ app, available for iOS and Android, allows users to set alarms that notify them of deviations in tire pressure from set levels. The app lets users adjust transmission frequencies and configure active and sleep modes to enhance battery efficiency. The extended battery life is due in part to the low power consumption of the Nordic SoC. The nRF52810 SoC is designed to minimize power usage, featuring a 2.4 GHz radio with low peak RX/TX currents and an automatic power management system.
