  • Publication number: 20230343149
    Abstract: An example computer system includes memory hardware configured to store a machine learning model and historical driving data vector inputs, and processor hardware configured to execute instructions including training the machine learning model with the historical driving data vector inputs to generate a reconstructed driving data output, wherein the reconstructed driving data output includes at least one reconstruction error score indicative of a likelihood that a driving data input corresponds to a desired driving behavior, obtaining a current driving data input, and supplying the current driving data input to the machine learning model to generate a reconstruction error score based on the current driving data input. The instructions may include determining a driving score according to the reconstruction error score, identifying at least one driver notification according to the determined driving score, and transmitting the identified at least one driver notification to a computing device or display.

  • Patent number: 10936890
    Abstract: A vehicle device receives image data transmitted from a compartment camera photographing a driver. The vehicle device analyzes the image data received from the compartment camera, and detects a heart rate of the driver. The vehicle device wirelessly communicates with one or more wearable devices possessed by one or more people who ride on a vehicle. The vehicle device identifies a wearable device possessed by the driver by comparing biometric information transmitted from the one or more wearable devices with the heart rate of the driver.

  • Publication number: 20210001914
    Abstract: A vehicle input device includes a touch sensor provided in a grip portion of a steering wheel, a holding position determiner configured to determine whether a user is holding the grip portion and determine a holding position at which the user is holding the grip portion based on an input signal from the touch sensor, an operation area setting unit configured to set an operation area of the touch sensor at a position adjacent to a thumb and an index finger of a user's hand based on the holding position, and an operation detector configured to detect an operation by a finger of the user to the operation area of the touch sensor.

  • Patent number: 8818459
    Abstract: A hands-free device disposed in a vehicle identifies a speech direction of an outgoing voice when a hands-free call operation is received. The device extracts callee information from the outgoing voice provided by an occupant to identify a portable communication terminal. In particular, the portable communication terminal is identified when the callee information extracted is registered in a telephone book data of the portable communication terminal. When the speech direction of the outgoing voice is identified as a driver side, the portable communication terminal identified is linked to the driver as a driver-linked terminal. Accordingly, a call being received by a portable communication terminal that is linked to the driver is performed as a hands-free call, whereas a call being received by a portable communication terminal not linked to the driver is not performed as a hands-free call.

  • Publication number: 20120244814
    Abstract: When determining that radio waves of a WiFi link are deteriorated during a WiFi handsfree voice call, a handsfree apparatus notifies a user that the radio waves of the WiFi link are deteriorated. When the user selects a switchover from the WiFi link to a Bluetooth link, the handsfree apparatus starts a BT handsfree voice call by connecting the Bluetooth link, and then ends the WiFi handsfree voice call by disconnecting the WiFi link, which is deteriorated. Thus, a handsfree voice call between the handsfree apparatus and a partner communication apparatus can be continued without interruption.

  • Patent number: 8190214
    Abstract: An in-vehicle handsfree apparatus establishes a handsfree profile connection with at least two cellular phones. It may be determined that a first cellular phone and a second cellular phone are receiving incoming calls at the same time, or that while a first cellular phone is calling, a second cellular phone is receiving an incoming call. In such a case, based on attributes (for example, a holder or intended use) of the first and second cellular phones, a notice manner of information on incoming call or information on telephone call is differentiated, for instance, in regard to a background color of a display window.

  • Patent number: 8175657
    Abstract: When an in-vehicle handsfree apparatus establishes concurrent connection with a cellular phone via a Bluetooth interface device with respect to a phone book access profile (PBAP) for realizing a phone book data transfer as well as a handsfree profile (HFP) for realizing a handsfree phone call and a message access profile (MAP) for realizing a mail transfer, the in-vehicle apparatus is configured to start a connection process of PBAP without inserting the connection process of MAP, after the completing of the connection process of HFP.
