Utilizing Time Related Property Of Fault Signal (e.g., Duration, Etc.) Patents (Class 701/33.6)
  • Patent number: 8473142
    Abstract: The present invention concerns a method for determining a conformity between a representation of an environment and said environment, wherein said representation of the environment constitutes a representation in at least two dimensions, where a distance between two points in the representation has a known relation to the corresponding distance in said environment, characterized in that said determination involves the step of determining a first set of parameter values for a first position in said representation of the environment, comparing said first determined set of expected parameter values with a second set of parameter values, where said second set of parameter values has been determined for a second position, where said second position constitutes a position in said environment that essentially corresponds to said first position, and using said comparison to determine a measure of conformity between said environment and said representation of the environment.

  • Patent number: 8467929
    Abstract: A controller for determining whether a previously-detected vehicle wheel speed sensor malfunction still exists. The controller includes an electronic, non-volatile memory, and an electronic processing unit connected to the electronic, non-volatile memory. The electronic processing module includes a malfunction monitoring module, a failure handling module, and a signal checking module. The malfunction monitoring module monitors the operation of at least one wheel speed sensor and generates a fault signal when the at least one sensor malfunctions. The failure handling module causes drive cycle information and the fault information to be stored in the electronic, non-volatile memory. The signal checking module performs a signal check on information from the at least one wheel speed sensor. A tell-tale indicator is deactivated and/or a vehicle control system resumes normal operation if the wheel speed sensor passes the signal check.

  • 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.

  • Patent number: 8442717
    Abstract: In an ECU provided for idle-stop control, when a user start command is outputted from an ECU to start an engine in response to a manual start operation of a driver, transistors are turned on and a solenoid is operated to engage a pinion gear of a starter with a ring gear. After a delay period of a delay circuit, a transistor is turned on by an output of the delay circuit and an electromagnetic switch is turned on to energize a motor of the starter. A microcomputer measures an actual delay time from when the user start command is outputted to turn-on of the transistor and checks whether the measured time corresponds to a normal time of the delay time.

  • Patent number: 8392060
    Abstract: The present invention relates to a method for feedback of states of an electric component to an engine control device of an internal combustion engine using a control unit for the electric component including a detection device configured to detect faults. The method includes configuring the control unit, connecting the control unit to the engine control device via a signal line, receiving a PWM signal generated in the engine control device, tying the signal line to ground for a feedback of data of the electric component to the engine control device; and identifying a fault based on a duration of the connection to ground.

  • Patent number: 8285545
    Abstract: A voice command acquisition method and system for motor vehicles is improved in that noise source information is obtained directly from the vehicle system bus. Upon receiving an input signal with a voice command, the system bus is queried for one or more possible sources of a noise component in the input signal. In addition to vehicle-internal information (e.g., window status, fan blower speed, vehicle speed), the system may acquire external information (e.g., weather status) in order to better classify the noise component in the input signal. If the noise source is found to be a window, for example, the driver may be prompted to close the window. In addition, if the fan blower is at a high speed level, it may be slowed down automatically.

  • Publication number: 20120209471
    Abstract: A method for monitoring the driving behavior of a railway vehicle, wherein at least one measurement variable characterizing the vibrational behavior of at least one wheel set of the railway vehicle, is captured by at least one sensor providing a corresponding measurement signal. The method includes the steps of identifying at least one significant event or a combination of multiple significant events within the time trace of the measurement signal and identifying the event time at which the significant event took place, deriving the frequency from the time trace of the measurement signal starting from the event time, comparing the derived frequency to at least one stored reference frequency, evaluating the vibrational behavior of the wheel set as a function of the deviation of the derived frequency from the at least one stored reference frequency.
