Yokohama Rubber Company the 8th largest tire manufacturing company in the World has announced that it has begun practical testing of its newly developed “Tire Air Pressure Remote Access System” (TPRS) system which enables the monitoring of tire conditions remotely.
The Testing began in May and is being conducted together with the Company’s tire sales subsidiary Yokohama Tire Japan and with the cooperation of Kyoto Taxi and Koshin Taxi.
The system, developed by Yokohama, involves an air pressure sensor attached to the inner surface of tires and will be tested in taxis operated by the two companies in Kyoto Prefecture, the tire maker announced on 20 June. The system aims to reduce significantly the time spent checking tires at the start of each day and records air-pressure data. Using TPRS, Yokohama Rubber aims to establish a new business model that contributes to driver safety and enhances the economic efficiency of vehicle operation.
It also enables early detection of slow punctures that cause gradual air leakage. It also contributes to proper tire maintenance, helps prevent inspection irregularities, and improves fuel efficiency by maintaining proper air pressure. In addition, the system’s ability to detect tire abnormalities in real-time can help prevent accidents.
The system transmits detection data to a cloud server, enabling the taxi company’s fleet managers and Yokohama Rubber’s sales offices to monitor tire air pressure. An alarm device installed in the taxi operator’s office will notify the fleet manager when air pressure falls to a level that will reduce fuel efficiency or indicates a possible slow puncture.
Unlike the conventional valve-type TPMS (tire pressure monitoring system), an air-pressure sensor attached to tires’ inner surface can be used on a wide variety of vehicles and wheels as an aftermarket part that can be used with any wheel type.
Yokohama Rubber has previously conducted practical testing of its TPRS for corporate cars and car-sharing companies, but the current test is being conducted with taxi companies who require strict tire management with the aim of establishing a business model that contributes to the improved safety and economical operation of taxi fleets.
