    Abstract: The present disclosure is applied to a variable group calculation apparatus for calculating an undetermined variable group that simultaneously minimizes a difference value and a data value. The difference value is a difference between an added composite value, which is obtained by adding and combining the undetermined variable group and a dictionary data group, and an observation data group. The data value includes the difference value and a regularization term of the undetermined variable group. The variable group calculation apparatus of the present disclosure includes a convolution unit configured to convert the regularization term to a convolution value for an L1 norm using the undetermined variable group and a mollifier function, and a calculation unit configured to perform the calculation using the regularization term, which is converted to the convolution value by the convolution unit.

    Abstract: A steering control device includes a driving support ECU. When white line recognition loss, which is a state in which white lines are not properly recognizable, has occurred during execution of an LCA, the driving support ECU calculates a target trajectory for returning a yaw angle to a state immediately before the start of the LCA.

The control device alternately switches the air-fuel ratio between a rich air-fuel ratio and a lean air-fuel ratio, and controls the air-fuel ratio so that the air-fuel ratio is switched from the lean air-fuel ratio to the rich air-fuel ratio when the oxygen storage amount of the catalyst is greater, when the calculated EGR rate is relatively high, compared to when it is relatively low.

  • Publication number: 20180347431
    Abstract: A heat exchanger includes an introduction path and a discharge path. The introduction path introduces the heating medium to upstream portions of heating medium passages. A length of the introduction path along a third direction is reduced gradually from an upstream end portion of the introduction path towards a downstream end portion of the introduction path. The discharge path discharges the heating medium to an outlet portion. A length of the discharge path along the third direction increases gradually from a first portion towards a second portion. The first portion is disposed downstream of the upstream end portion of the introduction path in the flow direction, and the second portion is disposed downstream of the downstream end portion of the introduction path in the flow direction.

    Abstract: In the plasma spraying according to the present embodiment, the zircon powders are excessively heated to raise the average temperature of the molten particles to a temperature range of 2820 to 4200° C. As a result, SiO2 in the zircon powders is vaporized, and the component ratio of ZrO2 in the molten particles is relatively increased. Such zircon powders land on the surface of the base material, and the deposit coagulates, the coagulum forms a thermal sprayed coating with a high composition ratio Zr/Si.
