摘要： Method and system for determining a route for a vehicle. The method associates a navigation module to a vehicle fitted with tires and a tire monitoring unit to at least one tire fitted to the vehicle. The monitoring unit has a sensing element to generate a sensing signal descriptive of deformations undergone by the tire. The deformations form a contact area between the tire and a rolling surface on which the tire rotates. During rotation of the tire, the sensing signal, including the sensing signal generated in correspondence of passages of the sensing element through the contact area, is undersampled for a number of passages sufficient to obtain an estimated length of the contact area. The weight of the vehicle is then estimated based on such estimated length, and at least one route among two or more routes is selected, based on such estimated weight of the vehicle.

摘要： Methods and apparatus forming part of a vehicle sensor system (100) comprising a plurality of sensor units (104a-f) and a controller (102). A sensor unit comprises: a motion sensor (417) configured to determine a first speed of the sensor unit; and a transmitter (402) configured to transmit first identification data to the controller if the first speed of the sensor unit exceeds a first threshold. The motion sensor is further configured to determine a second speed of the sensor unit a period of time after determination of the first speed of the sensor unit, and the transmitter is configured to transmit to the controller second identification data if the second speed of the sensor unit exceeds a second threshold. The controller comprises: a receiver (304) configured to receive the first identification data, and further configured to receive the second identification data a period of time later; and a sensor unit assigner (320) configured to assign the sensor unit to the controller if the first identification data and the second identification data are received.

摘要： A method for obtaining the deformation of a tire casing subjected to a load, rotating at a rotational speed W, comprises the following steps: acquiring a signal comprising the amplitude of the acceleration in the direction normal to the crown when running at the rotational speed W; delimiting the signal over a number of wheel revolutions, so as to construct a wheel revolution signal; determining a reference acceleration; defining a first energy density S which is a function of the wheel revolution signal, and of the reference acceleration, and which is denoted S+ when the wheel revolution signal is above a threshold value A, or is denoted S− when the wheel revolution signal is below or equal to said threshold value A; and identifying the deformation generated by the load as a function of the reference acceleration and of the first energy density S.

摘要： In an embodiment, a system for wear monitoring, includes a wear surface, a metallic reflector embedded in the wear surface, a radio-wave transmitter, and a radio-wave receiver. The metallic reflector reflects radio waves transmitted by the radio-wave transmitter for detection by the radio wave receiver. Attenuation of the radio waves between transmission by the radio-wave transmitter and detection by the radio-wave receiver indicates a degree of wear of the wear surface.
