The present invention relates to methods, systems and devices for integration of tire pressure monitoring sensors with a tire pressure monitoring system utilizing a telecommunication device.
Commercial and non-commercial vehicles now have tire pressure monitoring systems (TPMS) which include a central module, integrated or in communication with an electronic control unit of the vehicle, and tire pressure monitoring sensors (TPM sensors) for each vehicle wheel unit. In general, the TPM sensors monitor tire pressure within a respective tire and transmits a wireless signal to the central module which is indicative of tire pressure. Should the sensed pressure be outside of an acceptable range or a substantial change in tire pressure occur, an alarm is generated and transmitted to the user of the vehicle.
Over time, TPM sensors require replacement by service technicians due to damage, depleted battery or otherwise. This requires installation and integration of new TPM sensors with a TPMS of a vehicle. During this process, in one configuration, the technician places the vehicle in a learning mode requiring each TPM sensor to be triggered for identification purposes. The technician then sequentially triggers each sensor of a wheel unit, utilizing a TPMS tool, causing each sensor, new or existing, to transmit a wireless signal to a control module of the TPMS. These tools communicate with a sensor through low frequency signals which communicate with the TPMS through a higher frequency radio signal. The control module records the identification number of each signal so as to interpret the location of TPM sensor data during operation thereof.
More recently, certain manufacturers have offered TPM sensors that can be configured, through flash programming or program selection, by a service technician with suitable operating software for a particular make, model and year of a vehicle. Unfortunately, this requires the purchase and maintenance of expensive tools, such as the TECH400SD, sold by Bartec USA at www.bartecusa.com, or otherwise. The purchase and maintenance of TPM sensor configuration tools can be considerable as service stations should maintain one configuration tool for a certain amount of vehicles anticipated to be serviced. Accordingly, the greater number of anticipated clientele, the more configuration tools must be on hand and maintained. Furthermore, the substantial cost of configuration tools effectively eliminates individuals from servicing their own TPMS.
In another aspect, with the continual expansion of the TPMS market, due to increasing numbers of vehicles being sold with TPMS, TPM sensor tools must be continually updated to include not only new TPMS models introduced every year, but also improved software for existing TPM sensors. Accordingly, existing configuration tools must have new memory modules purchased and installed to include the new TPMS data. Alternatively, each configuration tool must be connected to a computer in order to download program software updates, via the internet, or otherwise. In either instance, time must be dedicated for the accessing and installation of updated program software for each sensor tool.
The present invention provides improved methods, systems and devices for generating communication between new or existing TPM sensors with existing TPMS of a vehicle. The present invention further provides improved methods, systems and devices for integrating new TPM sensors with existing TPMS. The present invention further provides improved methods, systems and devices for configuring or programming replacement TPM sensors so as to communicate and be integrated with an existing TPMS.
The features of the present invention are predicated, in part, through the utilization of everyday electronic devices to cause communication, configuration and/or programming of TPM sensors with existing TPMS. More specifically, the features of the present invention are predicated, in part, through the use of telecommunication devices, such as smart phones or otherwise, for the integration of TPM sensors with existing TPMS. The features of the present invention are further predicated, in part, upon the use of a low frequency transmission device that is operable to communicate with an existing telecommunication device and for communication with TPM sensors so as to cause communication between the TPM sensor and a TPMS, configure or program a TPM sensor to function with a TPMS, or combinations thereof. In one configuration, the low frequency transmission device is further configured for communication with a TPMS control unit, electronic control unit of a vehicle or both, for transmitting and receiving information pertaining to one or more TPM sensors. Through the features of the present invention, the use and cost of additional TPMS components and downtime for maintaining the same are greatly reduced.
In view of the foregoing, in a first aspect, the present invention provides a method of integrating a tire pressure monitoring sensor with a tire pressure monitoring system of a vehicle. The method includes the step of establishing a communication link between a telecommunication device and a tire pressure monitoring sensor, the communication link including a low frequency transmission device. The method further includes transmitting a signal through the communication link to cause the tire pressure monitoring sensor to communicate with a tire pressure monitoring system of a vehicle.
In another aspect, the present invention provides a system for integrating a tire pressure monitoring sensor with a tire pressure monitoring system of a vehicle The system includes a telecommunication device having a memory device with suitable software for communicating with a tire pressure monitoring sensor. The system further includes a low frequency transmission device in communication with the telecommunication device through a first communication link. The low frequency transmission device is configured to form a second communication link with a tire pressure monitoring sensor, wherein through the low frequency transmission device the telecommunication device is configured to cause the tire pressure monitoring sensor to communicate with a tire pressure monitoring system of a vehicle.
In another aspect, the present invention provides a hand-held tool configured to integrate a tire pressure monitoring sensor with a tire pressure monitoring system of a vehicle. The tool includes a telecommunication device and a low frequency transmission device. The tool further includes a memory device having software instructions for generating a communication link between the low frequency transmission device and a tire pressure monitoring sensor. The software instructions are configured to cause the tire pressure monitoring sensor to communicate with a tire pressure monitoring system of a vehicle.
In another aspect, the present invention provides a computer-readable memory device storing computer program instructions which when executed by a computer comprising at least one processor results in: i) generating a communication link between a telecommunication device and a low frequency transmission device; and ii) transmitting a signal through the communication link to cause the tire pressure monitoring sensor to communicate with a tire pressure monitoring system of a vehicle.
