A vehicle lane keep control apparatus includes a steering control processor. the steering control processor is configured to, upon detection of a skid of a vehicle during control, switch modes from a lane keeping mode to a slip-handling mode, perform a steering control to allow the vehicle to have a stable attitude, and restart the lane keeping mode. The control includes setting a target route on which the vehicle is to travel, calculating a control amount for an electric power steering motor of the vehicle based on at least an amount of shifting from the target route, and causing the vehicle to travel along the target route.

A multilayer coil component includes an element body having a multilayer structure including a first element body portion formed of a ferrite element body material, and a second element body portion laminated on the first element body portion and formed of a ferrite element body material having a composition different from the ferrite element body material forming the first element body portion, a multilayer coil having an axis parallel to a lamination direction of the element body, and a stress alleviation portion provided in an inner region of the multilayer coil when viewed from the lamination direction. In the multilayer coil component, the stress alleviation portion is provided in the inner region of the multilayer coil in which a stress tends to be concentrated to alleviate the stress in the inner region of the multilayer coil, and thereby occurrence of cracking in the element body can be suppressed.

A vehicle driving support apparatus includes a forward environment recognizing device configured to recognize a traveling environment forward of a vehicle, a control device configured to perform active lane keep centering control based on the traveling environment, an electric power steering device configured to apply an assist torque to control a turning angle of wheels in accordance with a steering angle received from a steering handle, and a driver monitoring system configured to detect biological information of a driver who drives the vehicle. During execution of the active lane keep centering control, the control device is configured to count the number of times a driver's line-of-sight direction in the biological information has deviated from a target route direction of the vehicle and if the counted number of times is greater than or equal to a predetermined threshold count, reduce the assist torque stepwise as the counted number of times increases.

Vehicle driving support apparatus

A driving assistance apparatus for a vehicle includes: an environment information acquisitor that acquires environment information in front of the vehicle; a target route setter that sets a target route; and a controller that causes the vehicle to travel along the target route. The controller includes: an intersection determiner that determines whether there is an intersection in front of the vehicle; a right-left turn determiner that determines whether the vehicle turns right or left; a multiple intersecting road determiner that checks whether there is a second intersecting road; a route generator that generates a correct route and a quasi-correct route; an estimated traveling route setter that sets an estimated traveling route; a lateral position distance calculator that calculates a correct-route-side lateral position distance and a quasi-correct-route-side lateral position distance; a lateral position distance comparator that compares the lateral position distances; and an intervention controller that sets a traveling direction.

A vehicle light distribution control apparatus includes a first surrounding environment recognition device configured to recognize a surrounding environment around a vehicle and detect first object information in the recognized surrounding environment, and a second surrounding environment recognition device configured to acquire map information in a predetermined range based on the positional information of the vehicle, and second object information included in the acquired map information, and an illumination device configured to radiate illumination light. An illumination control unit is configured to compare the first object information and the second object information, identify objects that are detected in the second object information and are not detected in the first object information, set the objects as light distribution candidate objects respectively, set light distribution priority levels of the light distribution candidate objects respectively, and perform the light distribution control based on the light distribution priority levels.

A composite magnetic body includes soft magnetic metal particles and non-magnetic ceramic particles each having a particle size (D50) smaller than that of the soft magnetic metal particles.

Composite magnetic body and electronic component

In a multilayer coil component, a ferrite element body includes a first element body portion and a second element body portion adjacent to each other in an axial direction of the multilayer coil, in which a dielectric constant of the second element body portion is lower than a dielectric constant of the first element body portion, and a magnetic permeability of the second element body portion is higher than a magnetic permeability of the first element body portion. The inventors newly found that the first element body portion and the second element body portion contribute to coil characteristics when a coil winding portion is provided to extend over the first element body portion and the second element body portion. In the multilayer coil component, desired coil characteristics can be obtained by adjusting proportions of the first element body portion and the second element body portion in the ferrite element body.

The inventors have newly found that, even when a composition of a first element body portion and a composition of a second element body portion are different from each other, a high bonding strength at an interface between the first element body portion and the second element body portion can be obtained when both the first element body portion and the second element body portion contain ZnSiOas a constituent component. That is, when the first element body portion and the second element body portion contain ZnSiO, a bonding strength at the interface is improved compared to a case in which the first element body portion and the second element body portion do not contain ZnSiO.
