METHOD AND SYSTEM FOR EVALUATING TIRE STATE AND TIRE CONFIGURED FOR SAME
The disclosed technology generally relates to tires, and more particularly to a method of and a smart tire system for evaluating a state of a tire, and providing an alarm, and to a smart tire configured for the method and the system. In one aspect, a method includes determining whether an abnormality or a problem exists in a state of a tire, by processing a tire state value from a TPMS sensor. Processing the tire state can be carried out by a sensor processor and/or a sensor information processor. The method additionally includes providing an alarm to a user, e.g., a driver. The method additionally includes verifying the determination of whether there is an abnormality or a problem. Thus, the disclosed method includes determining the state of a tire and providing an alarm, where the alarm has high reliability because it is generated based on examination of various parameters of the tire state, including, e.g., pressure, temperature and/or acceleration. The disclosed technology additionally relates to a system and a smart tire configured to implement the method. The method, the system and the tire according to embodiments may be improvements over existing methods, systems and tires.
CONFIRMATION OF TYRE MONITORING DEVICE STATUS
A method, apparatus and system are disclosed in which an indication given by at least one tyre monitoring device is confirmed by input received from another source is disclosed. The method includes causing, by the control device, at least one tyre monitoring device mounted on a wheel to measure a tyre pressure and to indicate a status using an indicator provided on the tyre monitoring device; receiving, from the at least one tyre monitoring device, data representative of the status of the at least one tyre monitoring device; receiving input representative of the status indicated on the indicator of the at least one tyre monitoring device; comparing the received data representative of the status with the received input representative of the status; and taking action based on the result of the comparing.
INITIALISATION OF TYRE MONITORING DEVICES
A method for initialising a tyre monitoring device including a wireless communication interface and tyre monitoring devices and systems using the method are disclosed. The method includes operating the tyre monitoring device in a first mode, in the first mode the tyre monitoring device is only responsive to an initialisation instruction received over the wireless communication interface from the second device; receiving an initialisation instruction over the wireless communication interface while operating in the first mode; and, responsive to the initialisation instruction, operating the tyre monitoring device in a second mode in which the tyre monitoring device is responsive to instructions received over the wireless communication interface. The first mode draws lower power than the second mode so power draw prior to initialisation, for example while storage awaiting use, is reduced.
