Patent number: 8682525Abstract: In telematics device mounted to a vehicle, an auxiliary processor detects an interrupt from an accelerometer and forwards the interrupt to a main processor—the interrupt wakes up the processor from a sleep mode. The main processor may then compare vehicle voltage and/or a value for a speed parameter to predetermined criteria to determine whether the interrupt was a false positive or if the accelerometer missed a detection of a user cranking up the vehicle. The main processor may also enter a conditional state if monitored information meets a minimum threshold. During the conditional state, the processor may operate according to rules for a current operational state and also according to rules for a changed state. The threshold for deeming a changed operational state is higher than for entering a conditional state to evaluate whether a change of operational state (i.e., on to off, or off to on) occurred.Type: GrantFiled: August 18, 2010Date of Patent: March 25, 2014Assignee: HTI IP, L.L.C.Inventors: Deep Kalinadhabhotla, Ivan Neflali Cardenas Perez, Bruce D.

Publication number: 20130278406Abstract: Systems and methods of determining tire load from measured tire parameters include using a piezoelectric based sensor to obtain one or more contact patch parameters (e.g., contact patch entry time, contact patch exit time total contact patch time and contact patch angle) and one or more additional sensors to obtain tire pressure. Selected contact patch parameter measurements and pressure values are then compared with known combinations of contact patch parameter values and pressure values stored in a look-up table. A corresponding determined tire load value is then provided as electronic output.Type: ApplicationFiled: December 30, 2010Publication date: October 24, 2013Applicants: MICHELIN RECHERCHE et TECHNIQUE S.A., COMPAGNIE GENERALE DES ETABLISSEMENTS MICHELINInventor: David Alan Weston

Patent number: 8565959Abstract: Multiple leak rate methodologies are combined and operate in parallel in a system for providing optimal results under different tire conditions. The methodologies may operate continuously or alternatively. Tandem large leak rate and low leak rate algorithms and methodology, for example, may deployed in a system in which, for large leak rates, a large leak rate methodology is employed and used to trigger a warning. At some pre-designated low leak rate threshold value, the system employs a low leak rate methodology either as an exclusive diagnostic monitor or in parallel with the companion large leak rate methodology. In the low leak rate analytical system, a change in tire pressure is correlated to a change in energy within a vehicle system pursuant to the algorithm W=??P*dx and derivative algorithms are used to calculate a final time and pressure drop at the final time as a basis for issuing a low pressure warning.Type: GrantFiled: December 3, 2004Date of Patent: October 22, 2013Assignee: The Goodyear Tire & Rubber CompanyInventor: Jack Edward Brown, Jr.

Patent number: 8564427Abstract: An apparatus to be attached to a rotary portion includes a substrate and a flat-shaped battery buried in resin. The substrate and the flat-shaped battery are connected to each other via a terminal in such a manner that one of a positive electrode can and a negative electrode can constituting the flat-shaped battery, the can having a smaller amount of deformation caused by bulging at a time of the expansion of the flat-shaped battery, is opposed to the substrate. A surface of the flat-shaped battery having a smaller amount of deformation is opposed to the substrate, and hence, adverse effects on the apparatus, such as the displacement of the terminal and the deformation of the substrate, can be reduced even when the flat-shaped battery expands.Type: GrantFiled: July 2, 2010Date of Patent: October 22, 2013Assignee: Hitachi Maxell, Ltd.Inventors: Noriyuki Yabushita, Toshikazu Yoshiba

Patent number: 8564428Abstract: A vehicle system includes a plurality of tire sensors, a plurality of low frequency (“LF”) antennas and an ECU. Each tire sensor is mounted in a respective tire of the vehicle. Each LF antenna is mounted on the vehicle and is configured to transmit an LF field to wake up two tire sensors. The ECU is in communication with the tire sensors, via a receiver, and the LF antennas. The ECU is configured to receive identification signals from the respective tire sensors and to determine locations of the respective tire sensors based on which antenna woke up the tire sensor transmitting the respective identification signal and whether the respective identification signal matches other received identification signals. The ECU is further configured to store the identification signals in the memory with the identification signals being associated with the respective tire sensors that transmitted the identification signal.Type: GrantFiled: August 5, 2010Date of Patent: October 22, 2013Assignee: Honda Motor Co., Ltd.Inventors: Brian K.

Patent number: 8532872Abstract: A tire pressure adjustment method and system is provided. The method includes receiving from a plurality of sensors in a vehicle, tread depth data associated with tread depths at multiple points on a tire tread comprised by a tire on the vehicle. The tread depth data is analyzed. A tire pressure value for an internal portion of the tire is determined based on results of the analysis. The tire pressure value is associated with modifying a group of tread depths during operation of the vehicle. In response, a command signal is generated. The command signal is configured to command a tire pressure modification device to adjust a current tire pressure value of the internal portion of the tire to the determined tire pressure value. The command signal is transmitted to the tire pressure modification device resulting in the current tire pressure value being adjusted to determined tire pressure value.Type: GrantFiled: January 13, 2012Date of Patent: September 10, 2013Assignee: International Business Machines CorporationInventors: Gregory J.
