Abstract
A tire wear detection apparatus includes a tire side device and a vehicle body side system. The tire side device includes a vibration detection unit, a vehicle speed estimation unit, a signal processing unit, and a first data communication unit. The vibration detection unit is configured to output a detection signal. The vehicle speed estimation unit is configured to estimate the vehicle speed. The signal processing unit is configured to generate wear data. The vehicle body side system includes a second data communication unit and a controller. The controller has a wear determination unit configured to determine a tire wear state based on the wear data. The signal processing unit is configured to acquire the detection signal within a detection signal acquiring range, and calculate a level value of a vibration level of the acquired detection signal within a predetermined frequency range based on a natural frequency of the tire.
