Tire Pressure Monitoring Systems communicates through Bluetooth LE

New Products |

According to technology company Sensata, the interest in BLE TPMS is on the rise as vehicles become more connected, electrified, and autonomous. While common in consumer applications like speakers and headphones, BLE is relatively new in the TPMS space for vehicle OEMs and is enabled by newer vehicle system architectures that can support BLE functionality.

Sensata’s new BLE TPMS leverages its field proven tire pressure monitoring sensors by replacing the UHF radio with BLE radio. The move enables the product to carry out two-way communications. These BLE TPMS solutions are available in both clamp-in and snap-in configurations, are optimized for long battery life, and deliver the same pressure, temperature and auto-location capabilities as Sensata’s existing UHF TPMS solutions.

BLE TPMS technology helps improve vehicle safety, performance and the driving experience. The technology can enhance advanced driver assist systems (ADAS) and augment remote diagnostics support. With Over-the-Air updates (OTA), drivers can download new tire-related features and software updates, enhancing their driving experience and avoiding a trip to the shop for service. BLE two-way communication also enables cyber security authentication, which is not possible with traditional one-way UHF, and adds a layer of protection from being hacked.

A leading vehicle maker in North America has selected Sensata’s solution for its electric vehicles, Sensata said without however naming this OEM. The production start is scheduled
