Sumitomo develops tyre wear detection technology


Sumitomo Rubber Industries (SRI) has added a new tyre wear detection technology to its Sensing Core tyre sensing technology. SRI hopes that this new function, which adds to the system’s existing tyre pressure, tyre load and road conditions detection capabilities, will help drive the progression of CASE (connected, autonomous, shared, electric), MaaS (mobility as a service ) and other new innovations for the automotive industry.

Sensing Core technology is able to detect various conditions related to tyres and the road, and was developed using SRI’s knowledge relating to the dynamic behaviour of tyres, as well as specialised digital-filtering technology that can analyse and interpret wheel-speed signals (which are transmitted as tyres rotate).

A unique feature of this technology, according to SRI, is that it uses the tyres as its sensors, meaning that it requires no additional sensor installation and is completely maintenance-free. Further, by sharing wheel-speed signal data and other relevant information over the Cloud, Sensing Core also allows for Cloud-based detection of potential issues at the regional level.

With this latest advancement, Sensing Core technology is able to detect tyre wear levels by calculating tread rigidity based on wheel-speed signals, engine data and other vehicle information. This technology not only alerts drivers about the wear condition of the vehicle’s tyres, but also allows for centralised management of tyre conditions over the Cloud. As such, Sensing Core holds potential for future applications among mobility service and transport service providers, helping ensure the overall safety of their operations while reducing maintenance costs.
