Abstract: In a driving assistance control apparatus for a vehicle, an acquisition unit is configured to acquire a detected traveling state of the vehicle and a detected traveling environment of the vehicle. A control unit is configured to, when a curvature radius of a travel trajectory of the vehicle is equal to or less than a predetermined radius threshold, cause a driving assistance unit to perform collision avoidance assistance using, as an activation area of the collision avoidance assistance, a reduced activation area obtained by reducing a reference activation area, and when determining that the vehicle is making a constant turn, cause the driving assistance unit to perform the collision avoidance assistance by using the traveling state of the vehicle and the traveling environment of the vehicle and the reference activation area even if the curvature radius of the travel trajectory is equal to or less than the radius threshold.

Abstract: An electric control device includes: a cam having a variable distance between an outer periphery and a center; a control shaft having one end, which contacts the outer periphery of the cam, and displaceable according to a rotation of the cam to adjust a valve lift amount; a motor rotating the cam; an angle detector detecting a rotation angle of the cam; and a controller. The cam includes multiple steps arranged on the outer periphery. The controller controls the rotation of the cam through the motor to match a detection angle of the angle detector with a target angle corresponding to a target valve lift amount. The controller stops rotating the cam through the motor when a difference between the detection angle and the target angle exceeds a first threshold, and the target angle corresponds to one of the steps.

Abstract: An electromagnetic-valve controller includes a control switch, a control portion regulating a supply current supplied to the electromagnetic valve by controlling a drive of the control switch and controlling to open or close the electromagnetic valve, and a current detection portion detecting the supply current. The control portion controls the drive of the control switch based on a detection result of the current detection portion. The control portion controls the drive of the control switch by using a first pulse signal having a duty ratio that is variable, in a closed period. The control portion controls the drive of the control switch by using a second pulse signal maintaining the supply current to be constant so as to maintain the electromagnetic valve to be in the fully closed state, in a closed-state maintaining period.
