  • Patent number: 11760322
    Abstract: An on-vehicle control device includes: a control unit that controls an attitude of a vehicle based on a value of a behavior sensor that detects a behavior of the vehicle, and prohibits control based on the behavior sensor when the value of the behavior sensor exceeds a threshold; and a travel environment determination unit that determines a travel environment of the vehicle based on image information captured by a camera, and in which the control unit changes the threshold to a lower value based on the travel environment determined by the travel environment determination unit.

  • Publication number: 20230090474
    Abstract: A vehicle control device causes an automatic brake to function even for an obstacle suddenly appearing from outside a sensor detection range in a place estimated to be dangerous such as an intersection. A vehicle control device calculates time-to-collision TTC based on a detection result of an obstacle sensor, and controls a brake, which is an actuator of a vehicle, based on the calculated time-to-collision TTC. The vehicle control device includes a determination unit that determines right turn or left turn of the vehicle, and a command unit that sends a command according to a determination result of the determination unit to the brake. When determining that the vehicle is turning right or left, the determination unit changes the time-to-collision TTC to a longer value by extending more than that at the time of traveling straight.

  • Publication number: 20210179123
    Abstract: Fail-safe is performed appropriately when an automatic driving ECU has a failure. Provided is an in-vehicle electronic control system including a recognition device that recognizes a situation outside a vehicle, a track calculation unit that calculates a track on which the vehicle travels, a failure diagnosis unit that diagnoses a failure of the track calculation unit, and an output unit that outputs a control signal used to control the vehicle, in which a control signal generated based on a brake control instruction generated by the recognition device and a control signal generated based on a track control instruction generated by the track calculation unit are input to the output unit, and when the failure diagnosis unit diagnoses that the track calculation unit has a failure, the output unit outputs a control signal generated based on the brake control instruction generated by the recognition device.

  • Patent number: 11023750
    Abstract: A video output system provided with a camera and an interface device, wherein the interface device is provided with a condition storage unit which specifies conditions under which a video is to be selected by the camera, and a video output unit which outputs a captured video received from the camera, and wherein the camera is provided with: an image sensor; a video generation unit which generates captured videos on the basis of the output of the image sensor; a condition acquisition unit which acquires said conditions from the interface device; a recognition/comparison unit which determines whether or not each captured video generated by the video generation unit meets the acquired conditions, and if it is determined that a captured video meets the conditions, generates identification information on the basis of recognition results of a subject to be recognized that is included in the captured image determined to meet the conditions, and that is associated with the conditions; and a camera calculation unit wh

  • Patent number: 9136566
    Abstract: A battery pack (21A) according to embodiments of the present invention comprises a plurality of battery modules (11A-11D) connected to each other in either one or both of a series connection mode and a parallel connection mode. An identifying information setting section (25) sets identifying information on each of the plurality of battery elements (11A-11D). A connection mode managing section (47) manages the connection mode between the plurality of battery elements (11A-11D) by using the identifying information set by the identifying information setting section (25). The identifying information on each of the plurality of battery elements (11A-11D) is made up of a combination of first identifying information on the potential of the one of the plurality of battery elements (11A-11D) and second identifying information on the battery pack (21A) serving as a superordinate battery element to which the one of the plurality of battery elements (11A-11D) belongs.
