摘要： A system for monitoring a condition such as tire air pressure where the monitor at each tire is remotely energized by radio waves, there being two embodiments disclosed for effecting this. A loop antenna concentrically mounted with respect to each tire receiver and/or transmits electrical energy to the remote location which is typically at the operator's console. Each pressure sensitive device is mounted away from the valve stem and may include a strain gauge mounted on the tire side wall or between the wall and rim. An infra-red detector may also be employed as a pressure monitoring device.

摘要： The disclosure relates to systems, methods and computer program products for detecting tire pressure loss in tires of a vehicle. The system comprises a sensor, which is arranged at the vehicle remotely from the tires, mechanically coupled at least indirectly to a chassis of the 5 vehicle, and configured to detect a property indicative of tilting spatial movement of the chassis. The system further comprises a processing unit, which is communicatively coupled with the sensor, configured to receive sensor signals from the sensor, the sensor signals being indicative of tilting spatial movement of the chassis, and configured to detect a tire pressure based on the sensor signals. The processing unit is configured to detect a tire pressure loss responsive to the 10 sensor signals indicating a tilting spatial movement of the chassis towards the at least one tire.

摘要： The invention provides a method and apparatus for monitoring tires on a vehicle to detect adverse tire operating states, by continuously measuring the distance between the associated vehicle axle (or a vehicle body part rigidly connected thereto) and the road while the vehicle is in operation. From this measurement, the tire deflection is determined, which represents a comparatively exact measure of the respective tire load. When the tire deflection determined leaves a predetermined desired range, a warning signal is transmitted.

摘要： A tire proposal system that proposes a tire of a vehicle to a user includes a processing unit that proposes an appropriate tire that is a tire appropriate for the vehicle based on a mileage and a driving time of each trip of the vehicle. With such processing, the appropriate tire is proposed to the user considering a traveling pattern (usage tendency) of the vehicle, which can be grasped from the mileage and the driving time of the each trip of the vehicle, thereby a tire appropriate for the traveling pattern of the vehicle can be proposed to the user as the appropriate tire.

摘要： A method and system for evaluating the reliability of data supplied by multi-function WFC sensors of tires of wheels of a vehicle for targeted applications, on the basis of the irregularities of the road, which use displacement data sent from the road handling adaptation equipment of the vehicle, enabling the variations in the road condition to be reflected. The system includes equipment for monitoring the wheel displacement data for adapting it to the variations of profile of the road on which it is traveling, in order to maintain a stable body position. The monitoring equipment is linked to the WFC sensors via a central processing unit which is capable of correlating data supplied by the WFC sensors and values of wheel displacement data supplied by the monitoring equipment for the purpose of weighting the values of at least one parameter obtained from the data delivered by the WFC sensors.

摘要： A vehicle tire load sensing system includes distance sensors mounted on the vehicle near each tire. The distance sensors generate distance signals representing a distance from the sensor to a track that is left in the soil during forward vehicle travel. Pressure sensors generate tire pressure signals. A temperature sensor senses the ambient temperature. A control unit receives the distance signals, the pressure signals and the temperature signals. The control unit compensates the distance signals as a function of the sensed temperature. The control unit generates filtered distance signals, and determines a tire deflection value from the filtered distance signal. The control unit determines the tire load as a function of the tire deflection value, the pressure signal and stored information relating tire load to tire deflection and tire pressure.

摘要： A device for detecting an abnormal state of a tire includes a wireless transceiver spaced apart from the tire and coupled to a vehicle, where the wireless transceiver transmits a radio signal to a ground surface and acquires delay information required to receive a reflected wave from the ground surface, and a control module that calculates a reference distance between the wireless transceiver and the ground surface based on the delay information, and detects an abnormal state of the tire, based on a reference distance change.
