  • Publication number: 20190300013
    Abstract: A vehicle driving assist system includes a steering wheel contact position detector, a steering torque detector, a driving mode setting calculator, and a steering override determiner. The driving mode setting calculator is configured to set a driving mode including a first driving assist mode, a second driving assist mode, and a manual driving mode. The driving mode setting calculator is configured, while traveling in a current driving mode that is the first driving assist mode or the second driving assist mode, to allow the current driving mode to continue in a case where the steering override determiner has determined that a steering torque detected by the steering torque detector is a false detection or to cause the driving mode to make a transition to the manual driving mode in a case where the steering override determiner has determined that the steering torque is a steering override intended by a driver.

  • Publication number: 20190300014
    Abstract: A driving assist system includes a steering wheel contact position detector, a steering torque detector, and a driving mode setting calculator. The steering wheel contact position detector includes a plurality of contact sensors disposed in a segmented state on a circumference of a holding part provided on a steering wheel, and is configured to detect a position on the steering wheel at which a driver makes a contact with the steering wheel. The driving mode setting calculator is configured to set a driving mode on the basis of a driving condition. The driving mode setting calculator is configured to determine whether a steering torque detected by the steering torque detector is a steering override intended by the driver or is a false detection, on the basis of the steering torque detected by the steering torque detector and a position at which the contact is detected by the contact sensors.

  • Patent number: 10360461
    Abstract: A travel control device for a vehicle is configured to execute a self-driving control based on a traveling state and traveling environment information of the vehicle. The travel control device includes a controller. The controller estimates execution of a right turn and a left turn from a traveling lane of the vehicle based on the traveling state and traveling environment information. When execution of either one of the right turn and the left turn from the traveling lane of the vehicle is estimated, the controller varies a traveling path from the traveling lane to a lane after the execution of the estimated turn according to the traveling state and traveling environment information to perform a right or left turn control of the vehicle.

  • Patent number: 10266174
    Abstract: A travel control device for a vehicle executes a self-driving control based on traveling environment information on which the vehicle travels and traveling information on the vehicle. In the device, a traveling environment information acquisition unit acquires the traveling environment information. A traveling information detection unit detects the traveling information. An unstable behavior detector detects an unstable behavior in one or both of a rolling direction and a yaw direction of the vehicle. A steering wheel holding state detector detects a state in which a driver holds a steering wheel. The first unstable behavior reducer reduces the detected unstable behavior by correcting a steering angle. A second unstable behavior reducer reduces the detected unstable behavior by selecting a predetermined wheel and applying a braking force to the wheel. A vehicle behavior controller freely operates the unstable behavior reducers according to detection results.

  • Publication number: 20190031236
    Abstract: A vehicle traveling control system includes: an electric power steering device, a positioning device, a communication device, and a control unit. The communication device receives wind information including information on a wind direction and a detection position of crosswind detected on a course of a host vehicle. The crosswind blows from a side with respect to the host vehicle. The control unit changes an assist force generation map of the electric power steering device such that an assist force that the electric power steering device generates with respect to steering performed up the crosswind becomes stronger than an assist force that the electric power steering device generates with respect to steering performed down the crosswind during traveling of the host vehicle through the detection position of the crosswind.

  • Patent number: 9709473
    Abstract: A method of measuring panel stiffness of an automobile part outer panel by pushing an indenter onto a surface of the panel in a pushing direction intersecting the surface under a load to deform the panel and measuring deformation of the panel includes arranging grids in a lattice form to a surface of a site of the panel; arranging markers previously knowing three-dimensional position information on a periphery of the site; pushing the indenter onto the surface of the site under the load and moving the indenter in a direction perpendicular to the pushing direction, during which the grids on the surface deformed by loading of the indenter are simultaneously and repeatedly shot from plural positions by plural cameras; and calculating position information of the grids corresponding to the markers based on the image data to measure change in deformation of the panel associated with movement of the indenter.

  • Patent number: 9637107
    Abstract: In a travel control apparatus for a vehicle, a travel environment information acquisition unit acquires travel environment information on a travel environment of the vehicle. A travel information detector detects travel information on the vehicle in order to execute automatic driving control based on such information pieces. A lateral force generator generates lateral force to be applied to the vehicle during the automatic driving control. A torsion bar is interposed on a torque transmission path of a steering system. A steering wheel angle detector detects a steering wheel angle. A lateral force detector detects the lateral force acting on the vehicle. An intervening steering operation determination unit determines that a driver has performed an intervening steering operation when a characteristic of the detected steering wheel angle and lateral force differs from a reference characteristic that varies univocally when the steering wheel is in a no load condition.
