  • Patent number: 11939015
    Abstract: By an offset amount being calculated based on a lateral position deviation from a target travel path at a forward point-of-gaze of a host vehicle at a time of a driver steering state, a series of vehicle control operations until switching back from the driver steering state to an automatic steering control, and traveling along an offset travel path, becomes smoother, whereby comfort when riding in a vehicle is increased.

  • Publication number: 20230307513
    Abstract: A semiconductor device includes a semiconductor layer, a conductive film, a first insulating film, and a second insulating film. The semiconductor layer has an element region where a semiconductor element is provided and a termination region surrounding the element region. The conductive film is provided on the element region and the termination region. The first insulating film is provided on the conductive film on the termination region and a portion of the element region adjacent to the termination region. The second insulating film that is lower in resistivity than the first insulating film, and higher in resistivity than the conductive film, is provided on the first insulating film.

  • Publication number: 20230071612
    Abstract: In order to generate an improved travel path with sufficient accuracy, a vehicle travel path generation device includes a first travel path generation part (60) which approximates a lane on which a host vehicle (1) travels to output first travel path information, a second travel path generation part (70) which approximates a road division line ahead of the host vehicle (1) to output second travel path information, a travel path weight setting part (90) which sets a weight between the first travel path information and the second travel path information, and an integrated path generation part (100) which generates an integrated path information using the first travel path information, the second travel path information, and the weight by the travel path weight setting part (90), wherein the travel path weight setting part (90) sets the weight, on the basis of at least one of outputs from a bird's-eye view detection travel path weight setting part (91), a vehicle state weight setting part (92), a path distance w

  • Publication number: 20210347359
    Abstract: A lane information detection unit detects the shape and the road width of a traveling lane of a vehicle. A present transverse position detection unit detects a present transverse position indicating a present traveling position of the vehicle in the width direction of the traveling lane. A driver-corresponding transverse position setting unit sets a driver-corresponding transverse position corresponding to a driving tendency of a driver. An upper/lower limit value setting unit sets upper/lower limit values that the driver-corresponding transverse position can take, in accordance with the road width. Then, when change in the road width is detected, a transverse position control amount calculation unit sets, as a target transverse position, the driver-corresponding transverse position within the upper/lower limit values in which the change is reflected, and calculates a transverse position control amount for the vehicle from the present transverse position of the vehicle.

  • Patent number: 11025165
    Abstract: With respect to a failure in voltage sensors each for detecting a high-voltage-side voltage in a DC/DC converter, it is so arranged that a circuit failure of the DC/DC converter is prevented, and that the DC/DC converter is continuingly controlled. Two voltage sensors are included therein each for detecting a high-voltage-side voltage, so that, even when a first voltage sensor for detecting a high-voltage-side voltage on one side fails to work properly, a control device turns on a second switching device, and detects a voltage by a second voltage sensor for detecting the high-voltage-side voltage on the other side, whereby a failure of the voltage sensor for detecting the high-voltage-side voltage is detected.

  • Patent number: 9321598
    Abstract: It is an object of the present invention to provide a conveyor which estimates weight of a transport object while it is carried without using devices such as a load cell which directly measures weight. The conveyor has a plurality of zones forming a series of carriage ways. An approach-run zone and a weight-measurement zone are arranged adjacently in the conveying direction and are provided with different drive motors. The drive motor of the approach-run zone and the drive motor of the weight-measurement zone are controlled with respectively different predetermined rotation speeds as their target rotation speeds. A rotation speed sensing means obtains the change of rotation speed of the drive motor in the weight-measurement zone when a transport object is conveyed into the weight-measurement zone from the approach-run zone, and a weight sensing means then calculates the weight of the transport object based on the change of the rotation speed.
