  • Patent number: 10336142
    Abstract: Provided is a device for detecting a low-pressure state of a predetermined tire, comprising an index value calculation unit, a resonance frequency calculation unit and a low-pressure detection unit. The index value calculation unit calculates a low-pressure index value from wheel speed information of front and rear tires, the low-pressure index value being obtained by comparing rotation speeds of the front and rear tires. The resonance frequency calculation unit calculates a resonance frequency from wheel speed information of a tire. The low-pressure detection unit eliminates an influence of an imposed load on a vehicle and detects the low-pressure state of the predetermined tire based on: a predetermined parameter that indicates a linear relationship between the resonance frequency and the low-pressure index value under a low-pressure condition of the predetermined tire; the low-pressure index value thus calculated; and the resonance frequency thus calculated.

    Abstract: A system and method improve guidance system performance. An accuracy improvement module (AIM) can be configured to compare observed and expected inclination compensation factors (ICFs) at a plurality of inclination angles to detect an inaccuracy in antenna height. In response to detecting an inaccuracy, an AIM can determine a revised antenna height that more accurately represents the height of an antenna above ground. A proposed antenna height can be determined using an observed ICF. A fixed vehicle body height can be subtracted from the proposed antenna height to provide a proposed tire radius. The proposed tire radius can be compared to a table of standard tire radii to determine a tire radius value, which can then be added to the fixed vehicle body height to provide a revised antenna height. The revised antenna height can improve the accuracy or calculated ground positions, thereby improving guidance system performance.

  • Patent number: 8547238
    Abstract: A system for confirming the detection of a fire using a plurality of radiation or flame sensors each equipped with a radiation detector and an optical filter having a spectral transmission characteristic in which at least one optical filter is redundant to at least one other optical filter. The result is a system having operationally redundant sensors. In use, if a fire is detected by one of the redundant sensors without including the other redundant radiation sensor in the fire detection calculation, then a fire detection algorithm can switch to the other operationally redundant sensor to check for confirmation of a fire. Due to the spatial separation and if the object is small and close, a different result will be obtained with the redundant detector being used in the calculation compared to the primary detector that is associated with the redundant detector.

  • Patent number: 8508354
    Abstract: An accelerator-off, fuel-cut traveling determining unit determines whether the number of engine revolutions of a vehicle is equal to or higher than a predetermined value, whether an accelerator opening rate is equal to or lower than a predetermined value, and whether a traveling state is an accelerator-off, fuel-cut traveling state where a quantity of fuel injection to an engine is 0. When it is determined that the traveling state is the accelerator-off, fuel-cut traveling state, the traveling distance adding-up unit adds up accelerator-off, fuel-cut traveling distances. A fuel-saving driving rating unit rates driving by a driver based on each of the added-up values which were added up by the traveling distance adding-up unit. A fuel-saving driving advice generating unit notifies the driver of a fuel-saving driving advice together with a rating result in accordance with the rating result.

  • Patent number: 8497771
    Abstract: A vehicle entry/tire pressure management 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. Some antennas can also be configured to transmit a SMART entry LF search field to wake up a portable transmission/reception unit for keyless entry of the vehicle. 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.

  • Patent number: 8473113
    Abstract: An on-line compensation apparatus for feedback positions of an encoder and method for operating the same are applied to a motor driven to rotate at a constant speed by a driver, thus compensating the errors of feedback positions of the encoder. First, a compensation quantity calculation unit is used to calculate the compensation quantity of feedback positions of the encoder. Afterward, a position interval judgment unit is used to determine the position interval of the compensation quantity. Finally, a compensation quantity modification unit is used to modify the compensation quantity by using different weightings. Therefore, the compensation quantity is modified by an iteration calculation to achieve that an error between the feedback position and an ideal position is in an acceptable region, thus increasing accuracy of the feedback position compensation of the encoder.

  • Patent number: 8452477
    Abstract: Wireless transmission from sensor devices included in tires is coordinated by a receiving unit associated with the tire, or transmission coordinator. In more detail, every sensor device is made aware of an overall time window available for transmission, and based on at least this information, it calculates a dedicated timeslot for the transmission of its data within such time window. This coordinated transmission makes possible a strong reduction of the probability of collisions and transmission errors, and reduces the number of transmissions, so as to comply with the limited power resources available at each sensor device.
