Title: Coil component
Inventor: YOSHINO HANAKO
IPC: H01F27/29
Filed: 2020-03-09
Abstract: To suppress changes in characteristics due to wire misalignment.SOLUTION: A coil component 1 includes a wire W wound around a core 13. A winding core portion 13 includes a winding region A1 located on the flange portion 11 side, a winding region A2 located on the flange portion 12 side, and a winding region A3 located between the winding regions A1 and A2.

Title: Vehicular control apparatus
Inventor: ITO KOHEI
IPC: B60W10/10
Filed: 2020-03-09
Abstract: To provide a vehicular control apparatus for appropriately suppressing a change in vehicular behavior and a change in load to an automatic transmission in the case of the internal combustion engine misfiring.SOLUTION: In a case where a misfire determination part 116 determines an engine 12 misfiring, an at-misfire shift control part 114a causes a shift ratio γ of an automatic transmission 24 to be down-shifted to a low-speed-side shift ratio that is lower than a lower-limit shift ratio, and therefore, when the engine 12 misfires, a damper spring is not elastically deformed as to fail an elastic deformation. This appropriately suppresses a large load change exerted to the automatic transmission 24 due to the misfire by the damper. Further, the at-misfire shift control part 114a suppresses a large load change exerted to the automatic transmission 24, eliminating a need to release a clutch when the engine 12 misfires, thus appropriately suppressing a change in vehicular behavior when the engine 12 misfires.SELECTED DRAWING: Figure 1
