The present disclosure provides a vehicle control system. The vehicle control system includes a transceiver operating in a sub-GHz frequency band configured to transmit and receive data from a RKE user terminal of the vehicle, a set of TPMS sensors and at least one remote control terminal located outside the vehicle; and an ECU connected to the transceiver and configured to: perform lock or unlock and engine start functions in responding to data from the RKE user terminal, receive tire pressure data from the TPMS sensors and control the remote control terminal in responding to a user action.

A tire pressure monitor includes a printed circuit board (PCB) and a sealed pressure chamber mounted to the PCB. The tire pressure monitor also includes a piston mounted adjacent to the sealed pressure chamber. The piston is configured to contact the sealed pressure chamber in response to an applied pressure. The tire pressure monitor also includes a liquid within the sealed pressure chamber. Translation of the piston causes the liquid to apply pressure to a pressure sensor. The pressure sensor is mounted within the sealed pressure chamber, and is configured to detect the applied pressure.

A tire operation service system includes a tire information monitoring device to monitor information on a tire and detect position information and unique identifying information, a tire operation server including a user information database stored with user information corresponding to the identifying information and a shop information database stored with position information on each shop and connected to the tire information monitoring device via a communication network, and a shop terminal and a user terminal connected to the tire operation server via a communication network, wherein the tire operation server includes a user information extraction unit, a nearby shop extraction unit, a shop-with-handling-ability extraction unit, and a shop information transmission unit.

A method of operating a Tire Pressure Monitoring System (TPMS) includes executing tire pressure monitoring of at least one tire installed on a vehicle in a first mode, and transmitting frequency signal loss information to a center if a loss of a frequency signal in the first mode occurs in a designated time period.

A system for locating a vehicle utilizing a zone posts in known locations that when the vehicle comes within a proximity of the zone post receives an identification signal from the vehicle and sends that identification signal on to a central command center. The identification signal may be provided by a dongle or a tire pressure monitoring system tire pressure sensor. The central command center may be queried with vehicle identifying information, and the location of the zone post that last sent the identification signal is provided as an indication of the location of the vehicle.

A method for monitoring a tire condition includes the following steps: sense a rotational speed of a tire of a moving vehicle via at least one monitoring device of a wireless monitoring system disposed in the vehicle; when the sensed rotational speed reaches a predetermined rotational speed range, obtain a condition of the rotating tire through at least one monitoring device to generate first condition data; compare the first condition data with a plurality of pavement feature data to obtain the corresponding pavement feature data; process with the obtained pavement feature data and the first condition data to filter a pavement feature out of the first condition data, generating second condition data; determine whether the condition of the tire is abnormal based on the second condition data; and send out a warning message when the condition of the tire is determined as being abnormal.

A system includes sensor modules, each associated with a wheel on a vehicle, and a receiver unit. Each sensor module calculates a rotation period associated with the wheel during turn mode vehicular motion and determines rotation direction of the associated wheel during straight vehicular motion. A data packet that includes a unique identifier for the sensor module, the rotation period, and the rotation direction are transmitted from each sensor module for receipt at the receiver unit. The receiver unit determines the steered wheels and non-steered wheels based on the rotation period, and the receiver unit can determine which wheels are on the right side or the left side of the vehicle based on the rotation direction. Knowledge of the steered and non-steered wheels and the rotation direction of the wheels, enables the receiver unit to assign locations of the sensor modules, and hence positions of the wheels of the vehicle.
