Abstract: A vehicle headlight (1) includes a first lamp unit (10) that includes a light distribution pattern forming unit (12) which forms a predetermined light distribution pattern (P1) according to the light amount of the light emitted from a plurality of light emitting elements (13), and a second lamp unit (20), in which a light distribution pattern (PL) of a low beam is formed by light emitted from the first lamp unit (10) and light emitted from the second lamp unit (20), and in the light distribution pattern (PL) of the low beam, the elbow point (EP) is included in a predetermined region (CA) formed by light including the light from the first lamp unit (10), and a first side region (SA1) and a second side region (SA2) sandwiching the predetermined region (CA) are formed by the light emitted from the second lamp unit (20).

Abstract: An event management apparatus includes an event queue register which associates each of a plurality of triggers with one of a plurality of task starting pointers, and a task execution controller that executes, when one of the plurality of triggers is generated, a task based on a task starting pointer associated with the generated trigger. The plurality of triggers includes an external trigger and a self-generated trigger which is generated in the event management apparatus.

Abstract: According to one embodiment, a method for detecting a periodic error, the method detecting a periodic processing error of a module controlled by a processor, the processor controlling a periodic processing by booting a peripheral module, the peripheral module outputting periodic triggers with a predetermined interval includes storing a first count value acquired from a counter, a second count value when the processing is started, and a third count value when the processing is completed, calculating a processing time on a basis of the three count values, and comparing the processing time with the predetermined interval to determine whether the periodic processing error occurs.
