  • Publication number: 20230093177
    Abstract: An operation device includes a first displacement portion that is displaceable by being operated by an occupant of a vehicle, a second displacement portion supported at the first displacement portion, and an extension/retraction locking portion. The second displacement portion is displaceable with respect to the first displacement portion by being operated by an occupant of the vehicle. In a state in which the first displacement portion is positioned at a first position, the extension/retraction locking portion restricts displacement of the second displacement portion with respect to the first displacement portion. In a state in which the first displacement portion is positioned at a second position, the extension/retraction locking portion permits displacement of the second displacement portion with respect to the first displacement portion.

  • Patent number: 11565635
    Abstract: A vehicle control device includes an actuation unit that actuates an anomaly control switch that acknowledges execution of safety control, which improves safety during driving of a vehicle, upon detection of an occupant in an anomalous state from a monitoring result of a state of the occupant of the vehicle. The actuation unit causes the anomaly control switch to be actuated to allow the occupant to recognize a control content of the safety control. The vehicle control device further includes an operation acknowledgement unit that acknowledges operation of the anomaly control switch and a controller that executes the safety control when the operation acknowledgement unit acknowledges the operation of the anomaly control switch.

  • Patent number: 10487546
    Abstract: This door locking device for a vehicle includes: an electronic key and an in-vehicle device. The electronic key stores a first threshold defining an extension of a first region in which an electric field intensity of a response request signal is strong and a second threshold for defining an extension of a second region in which an electric field intensity is weaker than the first region around the first region. The electronic key outputs, based on the electric field intensity of the response request signal and the first and second thresholds, a response signal including position information indicating whether the electronic key is in the first region, or is outside the first region but in the second region, or is outside the second region. Based on the received response signal, the in-vehicle device switches the door to an unlocked state or a locked state.
