  • Patent number: 8742936
    Abstract: A method and a control unit are provided for detecting when the driver of a motor vehicle becomes inattentive. In order to be able to reliably draw conclusions about the presence of inattentiveness of the driver, it is proposed to observe not only a steering inactivity phase but also a steering action which follows the steering inactivity phase. A detected implementation of the steering inactivity phase and of the steering action are logically combined with one another, and the result of this logic combination is then used as a measure of the severity of the inattentiveness of the driver. In addition, the measure of the severity of the inattentiveness of the driver depends on at least one driver-specific parameter which is determined during the execution of the method. The inattentiveness of the driver can also be detected during the time interval in which the at least one driver-specific parameter is determined.

  • Publication number: 20130194099
    Abstract: A driving assistance apparatus detects drowsiness of a driver of a vehicle while having a drowsy driving preventing function for awaking the driver having feeling of drowsiness. When erroneous detection of drowsy driving occurs frequently, the driver may deactivate the drowsy driving preventing function into an off state. The driving assistance apparatus determines a stress of the driver due to driving based on travel states of the vehicle obtained from a navigation apparatus such as traffic around the vehicle, a width and shape of a road traveled, installation states of traffic signals, and a velocity and steering angle of the vehicle. When the stress due to driving changes from a high status to a low status, the driver is regarded as being in a state of tending to be drowsy. The drowsy driving preventing function is thereby activated or turned on into an on state compulsorily.

  • Patent number: 8493220
    Abstract: Intelligent alarm clock arrangement adapted into an electric device and utilizing the microphone, loudspeaker or other alarming device, memory unit, processor and timer feature thereof. The apparatus is located near a sleeping subject so as to sample and analyze the statistical properties of sound signals produced by the movements of the sleeping subject and to classify the sleep states according to the analyzed signals into a peaceful calm deep sleep, a light sleep with arousals and awake periods associated with the movements. An alarm wakes up the subject during a pre-programmed time window, if there are arousals, awake state and movements present at that time to induce the awakening at a biologically advantageous instant. Instead of the local alarm function, the device may perform a remote alarm using a call or sending a message to a pre-programmed phone number when the awakening of the sleeping subject is detected.

  • Patent number: 8487775
    Abstract: A method of analyzing data based on the physiological orientation of a driver is provided. Data is descriptive of a driver's gaze-direction is processing and criteria defining a location of driver interest is determined. Based on the determined criteria, gaze-direction instances are classified as either on-location or off-location. The classified instances can then be used for further analysis, generally relating to times of elevated driver workload and not driver drowsiness. The classified instances are transformed into one of two binary values (e.g., 1 and 0) representative of whether the respective classified instance is on or off location. The uses of a binary value makes processing and analysis of the data faster and more efficient. Furthermore, classification of at least some of the off-location gaze direction instances can be inferred from the failure to meet the determined criteria for being classified as an on-location driver gaze direction instance.
