  • Product name: OBU+ TPMS
  • 产品名称:
  • Code:

The product is combination of the OBU and the TPMS (tire pressure monitoring system) to allow for ETC and tire pressure monitoring.

The product has two advantages which are multifunction and convenience.

The product is sensitive so it has high transaction success rate and rule out adjacent lane interference. Furthermore, the product supports Bluetooth connection which have multiple functions such as online activation, online recharging and remote update of programs. Additionally, the product has human voice broadcast and volume is adjustable. Therefore, the product can contribute to safe travel and clear transaction history.


The product has an efficient power management system which can sleep automatically and immediate wake-up function. Furthermore, the product has vehicle storage battery monitoring system which can automatically stop operation to prevent battery exhaustion. Lastly, the product accepts wide range of DC voltage inputs (9-16 V) and cope with the random fluctuation of the vehicle power supply.

Stable and reliable performance

The product is combination of ETC and TPMS. The product is stable and is guaranteed by the TS 16946 quality system.

Broad application

The product supports the urban free flow application and the ETCP parking lot application.


The product has super high monitor precision. The product’s error is ±0.1Bar. The product save power and be durable.


Product is combination of ETC and TPMS
