DEVICE, A TIRE PRESSURE MEASUREMENT DEVICE, A TIRE, A METHOD AND A COMPUTER PROGRAM TO OBTAIN INFORMATION INDICATING A TREAD DEPTH

摘要

Embodiments provide a device, a tire pressure measurement system, a tire, a method and a computer program to obtain information indicating a tread depth of the tire. The device to obtain information indicating a tread depth of a tire of a vehicle comprises a transducer to provide acoustical signals based on electrical signals and vice versa. The device further comprises a control unit, which is coupled to the transducer. The control unit is configured to provide the transducer with a first electrical signal based on which the transducer provides an acoustical transmit signal. The control unit is further configured to obtain a second electrical signal from the transducer. The second electrical signal is based on a reflected version of the acoustical transmit signal. The control unit is further configured to process the second electrical signal to obtain information indicating the tread depth of the tire.
