    Abstract: Methods and system are provided for controlling a vehicle. The methods and systems read sensors and estimate pneumatic trail for a tire of the vehicle based on the sensor readings. The methods and systems determine presence or absence of a tire lateral saturation condition based on a comparison of the estimated pneumatic trail for the tire of the vehicle with a pneumatic trail threshold indicative of a tire lateral saturation condition. When the tire lateral saturation condition is present, the methods and systems determine a control value and use the control value as an input to a vehicle control module. The vehicle control module is responsive to the tire lateral saturation condition based on the control value.

The circuit includes a sensor interface, connected to a sensor for supplying an analogue measurement signal (Vm) which is then filtered, an analogue-digital converter for digitally converting the filtered signal (Sm), and a digital signal control and processing unit for receiving a converted signal from the converter and supplying a digital measurement signal (SD). The sensor interface, the analogue-digital converter, and the processing unit are powered by a voltage regulator. The analogue and digital measurement signals are thus independent of any variation in the supply voltage (VCC) of the electronic circuit. A ratiometric unit, which may be an analogue multiplier or an analogue-digital converter, is powered by the supply voltage source (Bat) to recreate ratiometry on SA on the basis of Sm or SD.

    Abstract: A method and a device for recording angular velocity using a digital angular position transducer, for controlling an electric motor, for example. Instead of taking into account time-discrete changes directly in the form of step changes in the output signal, the recorded angular velocity change is taken into account only with an (increasing) proportion in the output. This permits a smoother curve in the case of not completely precise transducer wheels, whose imprecisions would otherwise lead to unnecessary reactions by the regulation. Large angular velocity changes, on the other hand, are reproduced directly, so as to take into account accelerations going along with them in an unaffected manner in the regulation.

  • Patent number: 7408447
    Abstract: A wireless, passive wheel-speed and detection system is provided for measuring the rate of rotation of a rotating component of a bicycle. The detection system includes a sensor arrangement having a first portion mounted on the bicycle and a second portion mounted on the rotating component. The sensor arrangement generates an input signal representative of a revolution of the rotating component. A transmitter circuit is operatively connected to the sensor arrangement for converting the input signal to a radio frequency signal and for transmitting the radio frequency signal. A controller receives the radio frequency signal and translates the radio frequency signal to a value indicative of a rate of rotation of the rotating component.

  • Patent number: 7301721
    Abstract: A falling sensor is provided, which detects a falling of a magnetic disk drive or an information processing device installed with said magnetic disk drive and which is effective for avoiding physical damages of magnetic heads and magnetic disk media. The magnetic disk drive or the information processing device, include an unload mechanism moving or evacuating said magnetic head from a surface of said magnetic disk media, and a falling sensor comprising a conductive flexible beams 9 or members having a compatible function, a conductive weight 10 supported by these beams and a conductive wall 11 arranged to be made contact or non-contact with said weight 10. The sensor can detect a falling of the magnetic disk drive or the information processing device which is typically a notebook personal computer installing with the magnetic disk drive, and evacuate the magnetic head by the unload mechanism. The conductive wall 11 can be formed as a tubular member.

  • Patent number: 7039507
    Abstract: An apparatus is provided for diagnosing the state of health of a vehicle and for providing the operator of the vehicle with a substantially real-time indication of the efficiency of the vehicle in performing an assigned task with respect to a predetermined goal. A processor on-board the vehicle monitors sensors that provide information regarding the state of health of the vehicle and the amount of work the vehicle has done. In response to anomalies in the data from the sensors, the processor records information that describes events leading up to the occurrence of the anomaly for later analysis that can be used to diagnose the cause of the anomaly. The sensors are also used to prompt the operator of the vehicle to operate the vehicle at optimum efficiency.

  • Patent number: 6966223
    Abstract: A vehicle speed display apparatus capable of displaying an accurate vehicle speed in either 2WD mode or in 4WD mode. A vehicle speed calculating unit 51 calculates the vehicle speed, according to the output from a wheel rotational speed sensor 22. A 2WD/4WD detecting unit 52 switches the destination of the vehicle speed calculated by the vehicle speed-calculating unit 51 between a 2WD correcting unit 53 and a 4WD correcting unit 54, depending whether the vehicle is traveling in 2WD mode or in 4WD mode. The 2WD correcting unit 53 corrects the vehicle speed in the 2WD mode using a first correction coefficient for the 2WD mode, and the 4WD correcting unit 54 corrects the vehicle speed in the 4WD mode using a second correction coefficient for the 4WD mode. The corrected vehicle speed is displayed by a vehicle speed display unit 55.
