  • Patent number: 11422044
    Abstract: A bridge driver circuit applies a bias voltage across first and second input nodes of a resistive bridge circuit configured to measure a physical property such as pressure or movement. A sensing circuit senses drive current, bias current and common mode current for the bridge driver and sums the sensed currents to generate a source current. The source current is processed to determine a normalized resistance and temperature of the resistive bridge circuit and from which a temperature dependent sensitivity of the resistive bridge circuit is determined. A voltage output at first and second output nodes of the resistive bridge circuit is processed to determine a value of the physical property. This processing further involves applying a temperature correction in response to the determined temperature dependent sensitivity.

  • Patent number: 9139054
    Abstract: Various embodiments of an apparatus and method for configuring a tire pressure monitoring system are disclosed. One method comprises rotating a first tire of a plurality of tires on a vehicle and receiving a signal indicative of the speed of rotation of the first tire from a wheel speed sensor associated with the first tire. A controller associates the first tire with a wheel location in response to receiving the signal from the wheel speed sensor. A tire pressure sensor in the first tire generates a tire characteristic signal in response to the rotation of the first tire. The controller receives the tire characteristic signal and associates the tire characteristic signal with the wheel location in response to receiving the tire characteristic signal within a predetermined time period from receiving the signal indicative of the speed of rotation of the first wheel.

  • Patent number: 9019094
    Abstract: A method is provided for real-time monitoring of tire pressure, wherein the pressure value determined by use of a pressure sensor in the tire is transmitted by an electronic wheel device, without the use of a trigger transmitter fixed on the vehicle, by radio, in short transmission intervals, to a monitoring device installed in the vehicle, only if, at least when the vehicle is not moving, the value is outside a prespecified normal range. When the vehicle is not moving, the electronic wheel device transmits a signal suitable for a system monitoring function, at certain time intervals and, using the same time frame or a whole-number fraction or multiple thereof, carries out a measurement of the tire pressure. The signal has a short transmission duration on the order of 25 ?s to 500 ?s.

  • Patent number: 9008903
    Abstract: The present disclosure presents a wheel diameter variation-detecting device capable of properly detecting relative variation in diameter between a plurality of wheels of a vehicle. The wheel diameter variation-detecting device can detect variation in diameter between a plurality of wheels of a vehicle, can detect rotational speeds of the respective wheels, and can calculate a variation parameter indicative of variation in diameter between the wheels using one of the wheels as a reference wheel, based on a result of comparison between the rotational speed of the reference wheel and that of one of the wheels other than the reference wheel. Further, the wheel diameter variation-detecting device can learn the variation parameter based on a value obtained by averaging a plurality of values of the variation parameter obtained before the detected travelled distance reaches a predetermined distance.

  • Patent number: 8941463
    Abstract: A system for an electric vehicle for authorizing the utilization of a reserve charge portion of a battery of the electric vehicle for powering the electric vehicle. The authorization system may include a remote device that communicates with the electric vehicle via a telematic link. Upon receipt of one or more data from the electric vehicle (e.g., reserve charge amount of the battery, recharge locations, warranty waiver information, billing information, previous authorization information, etc.) the remote device transmits an authorization signal to the electric vehicle for using at least part of the reserve charge portion of the battery based upon the data. The authorization system may incorporate live personnel for determining whether to authorize the electric vehicle or such authorization may be determined automatically by a processor of the remote device. The authorization system may be entirely local to the electric vehicle such that no remote device is needed.

  • Patent number: 8820154
    Abstract: A transmission device of a tire condition monitoring system comprises a sensor which detects, as tire information, the condition of gas filled into a tire cavity region, a transmitter which transmits the detected tire information by radio, and a housing which covers the sensor and the transmitter. A surface of the housing defines an opening that connects an internal space within the housing and the tire cavity region. The opening extends on the surface of the housing while forming the shape of a straight line, a curved line, or a combination of a straight line and a curved line. The maximum value of the opening width orthogonal to the direction in which the opening extends is 0.8 mm or less. Even if a flat tire is fixed using a puncture sealant, tire information such as tire pressure information can be appropriately measured and acquired by this transmission device.

  • Patent number: 8810386
    Abstract: A collision avoidance method for transmitting data from multiple wireless tire condition sensors on a vehicle is executed by each wireless tire condition sensor having a unique ID and multiple different wake-up times. After the sensor is operated to sense data, the method has steps of reading the ID and computing a determination value with the ID and a variable, selecting one of the wake-up times according to the determination result, and after the selected wake-up time expires, transmitting the sensed data. As the selected wake-up times of the sensors differ from one another, data collision at the receiving end arising from data transmission from the sensors can be avoided. Additionally, besides the wake-up time, a time gap between data transmitted twice consecutively from each sensor can be employed to achieve data collision avoidance.
