A system and method for resetting or reprogramming tire pressure monitoring system (TPMS) tire sensor data in a vehicle control system or electronic control unit (ECU). The system and method uses a single TPMS relearning tool which (a) receives a first TPMS tire sensor data signals from the TPMS tire sensors, (b) initiates the vehicle control system to enter into a relearning or resetting mode, and (c) re-emits the first TPMS tire sensor data signal as a second TPMS tire sensor data signal to the vehicle control system to reset the vehicle control system to the present TPMS tire sensor data. In one example, the TPMS relearning tool decodes, stores in memory, encodes and transmits a second TPMS tire sensor data signal which simulates the first TPMS tire sensor data signal.

Methods, systems, and computer program products for a wireless portable tire monitoring system are provided. According to one aspect, wireless portable tire monitoring system includes a portable monitor that receives sensor information from one or more tire-mounted sensors, each sensor being associated with a tire, and each tire being associated with a vehicle, and monitors tire status. Multiple vehicles may be monitored from the same portable monitor, and tires can be dynamically associated with or disassociated from a particular vehicle. Tire status may be displayed to the user in a manner that provides a graphic association between the tire status and the vehicle to which the tire is associated, including showing the location of the tire on the vehicle. The system may asynchronously alert the user if threshold conditions, such as low tire pressure, are detected.

An ECU is used to a tire pressure monitoring system of a vehicle. The ECU includes a contact storage portion and a post-replacement ID reporting section. The contact storage portion stores previously a contact of a management computer of a facility that the vehicle uses. The post-replacement ID reporting section transmits a post-replacement tire ID of a tire, which is substituted in the tire replacement, to the contact in the contact storage portion via a communication network when the tire replacement is detected by a tire replacement detection section. The management computer includes a registration change section that registers the post-replacement tire ID in a registration portion upon receiving the post-replacement tire ID.

A tire pressure monitor system tool that stores information regarding a plurality of tire pressure monitor systems. The information may include procedures for resetting and diagnosing the tire pressure monitor system. The tool may include a storing module that stores the information and a displaying module that causes the information to be displayed on a display of the tool. The tool may enable a user to input data regarding a vehicle. Based on the vehicle data input by the user, the tool may determine a tire pressure monitor system installed on the vehicle using the information stored. Based on the tire pressure monitoring system installed on the vehicle, the tool may determine one or more reset or diagnostic procedures that may be performed by the tool. The tool may also reference the owner's manual of the vehicle. The tool may also include an updating module that updates the information stored by the tool. The tool may also include an update interface that may be, for example, an RS232 port. The tool may interface with an electronic control unit of a vehicle.

A tire maintenance support program includes computer-implemented modules including: an information addition module, a graphic arrangement module, a user operation reception module, and a graphic movement module. The information addition module adds, to a tire graphic representing a tire, identification information on the tire, and adds, to a sensor graphic representing a sensor provided in the tire, identification information on the sensor. The graphic arrangement module arranges the tire graphic and the sensor graphic in the display screen based on axle arrangement information. The user operation reception module receives a user operation to move at least one of the tire graphic or the sensor graphic arranged by the graphic arrangement module. The graphic movement module moves at least one of the tire graphic or the sensor graphic according to a mounting position on an axle based on a user operation received by the user operation reception module.

Methods, system, apparatuses, and computer program products for securely pairing a vehicle-mounted wireless sensor with a central device are disclosed. In a particular embodiment, securely pairing a vehicle-mounted wireless sensor with a central device in accordance with the present disclosure includes a vehicle sensor device pairing with a vehicle control system (VCS) using a pre-shared passkey. The pre-shared passkey is shared between the vehicle sensor device and the VCS via an out-of-band exchange. This embodiment also includes the vehicle sensor device transmitting an identifier for a resolvable private address (RPA) to the VCS. In addition, the vehicle sensor device communicates with the VCS using the RPA. In this example embodiment, the RPA is periodically regenerated by the vehicle sensor device.

The method is for transmitting data identifying a valve of a wheel to a receiver on board a vehicle. The method includes, excitation of the valve, transmission by the valve of a frame including at least a code identifying the valve, and reception of the frame by the on-board receiver. The reception includes a refreshing of a memory range contained in the receiver by the data from the frame received. The method the includes a reading operation, by a diagnostic instrument, of the most recent data contained in the memory range, and an operation of writing to an area of memory dedicated to storing identifier codes, by a diagnostic instrument, of at least part of the data read including an identifier code. The writing operation is carried out after validation by an operator.

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 relates to a programming method for pressure sensors of vehicle tires, comprising: an activation of at least one programmable pressure sensor; a reception of at least one emitted signal; a determination of an identifier of said at least one pressure sensor activated on the basis of said at least one received signal and a determination of its current position in the vehicle; a research in a database of a pair stored identifier-stored position, in which the stored position is the current position of said pressure sensor; a comparison of said identifier with the stored identifier of said pair; and if the comparison is negative, a reprogramming of said at least one pressure sensor with the stored identifier.

The present invention relates to a programming method for pressure sensors of vehicle tires, comprising: an activation of at least one programmable pressure sensor; a reception of at least one signal from said at least one pressure sensor after said activation; a determination of a current position in the vehicle of said at least one activated pressure sensor; a research in a database of a pair stored identifier-stored position, in which the stored position is the current position of said pressure sensor; and a programming of said at least one pressure sensor with the stored identifier.
