A vehicle-mounted monitoring device includes a main body detachably arranged on a vehicle, and the main body is arranged with a circuit board, a display screen, a first communication module and a second communication module, and the display screen, the first communication module and the second communication module are all electrically connected to the circuit board. The first communication module is configured to receive image data wirelessly transmitted from at least one camera and then transmit the image data to the circuit board, the second communication module is configured to receive tire pressure data wirelessly transmitted from at least one tire pressure sensor and then transmit the tire pressure data to the circuit board, and the circuit board transmits both the image data and tire pressure data to the display screen for display.

A wheel assembly of a vehicle (e.g., a forklift or another material-handling vehicle) is monitored to obtain information regarding the vehicle, including information regarding the wheel assembly, which may be indicative of how the vehicle including the wheel assembly is used (e.g., a duty cycle of the vehicle and/or the wheel assembly), a state (e.g., a degree of wear) of the wheel assembly, loading and shocks on the wheel assembly, and/or a state of an environment (e.g., environmental temperature, a profile, compliance, or other condition of an underlying surface beneath the wheel assembly), and which may be, for example, conveyed to a user (e.g., an operator of the vehicle), transmitted to a remote party (e.g., a provider), and/or used to control the vehicle (e.g., a speed of the vehicle). This may improve use, maintenance, safety and/or other aspects of the vehicle, including the wheel assembly.

A method for detecting a foreign object under a vehicle fitted with a tire pressure monitoring system including at least two wheel units and a central unit including a communication device for communicating with each of the wheel units. The method includes a sounding step including a transmission phase which consists in transmitting at least one sounding signal from the first wheel unit to the second wheel unit across a transmission channel, and an analysis step which consists in comparing and in measuring differences in properties between the sounding signal received by the second wheel unit and a previously defined reference signal, and in determining whether the measured differences are characteristic of the presence of a foreign object present on the transmission channel taken by the sounding signal.

A tire sensor pairing system for tire sensors mounted in a tire or on a rim of a wheel for a vehicle is provided. The tire sensor pairing system comprising an Radio Frequency, RF, shielding construction arranged to envelope the wheel and one or more RF signal receivers, thereby shielding the one or more RF signal receivers from RF signals originating from outside of the RF shielding construction and enabling the one or more RF signal receivers to solely receive RF signals from tire sensors mounted in the tire or on the rim of the wheel.

The present invention provides an Active Tire Auto-Location systems for tire pressure monitor sensors and an operating method. The system includes a host, wheel axle rotation detection devices and tire pressure monitor sensors. By allowing the wireless tire pressure detector to receive and compare the rotation information of a toothed ring from the wheel axle rotation detection device and the tire rotation information from the wireless tire pressure detector, each wireless tire pressure detector can identify which wheel axle rotation detection device that corresponds to it. At the same time, the tire position where each wireless tire pressure detector is situated can also be determined. Compared to prior art, it is still possible for the present invention to determine the tire position where each wireless tire pressure detector is situated, without the need for additional modification to the host, thus significantly reducing the inconvenience in replacing tire pressure monitor sensors.

The present disclosure relates to a tire monitoring sensor, a system and a method for controlling the same. The system according to an embodiment of the present disclosure is provided in a vehicle, and may include: a tire monitoring sensor (TMS) comprising a battery and mounted on a tire or wheel of the vehicle, and detecting a condition of the tire; and a main transceiver provided at a position spaced apart from the TMS in the vehicle. The main transceiver comprises a plurality of coils configured to generate first magnetic fields by application of an alternating current. The plurality of coils is disposed such that the first magnetic fields are applied to the TMS sequentially according to a rotation of the tire or the wheel. The alternating current is applied to the plurality of coils such that adjacent first magnetic fields have opposite phases.
