Abstract: In a vehicle headlamp control apparatus, a light distribution control section controls light distribution of a headlamp based on a detected light control target object ahead of a vehicle and a detected behavior of the vehicle or an expected change thereof. When the behavior is in a first behavior state in which a change in the headlamp irradiation area becomes equal to or less than a predetermined amount or the behavior is expected not to change from the first behavior state, the light distribution control section causes the headlamp to project light in a standard pattern. When the behavior is in a second behavior state in which the change in the headlamp irradiation area exceeds the predetermined amount or the behavior is expected to change to the second behavior state, the light distribution control section causes the headlamp to project light in a pattern different from the standard pattern.

Abstract: Main cells that constitute a semiconductor element having a trench gate structure include first cells, and second cells having a structure in which gate insulating films are more easily broken by energization than those in the first cells, and the number of which is smaller than that of the first cells. At a time of driving the semiconductor element, a common gate drive voltage is applied to gate electrodes of the first cells and the second cells. An electrical characteristic is measured to detect failure of the second cells due to energization at the time of driving. The gate electrodes of the failed second cells are electrically isolated from the gate electrodes of the first cells so that the gate drive voltage is not applied to the failed second cells. The failure of the first cells is predicted based on the failure of the second cells.
