摘要： To accurately identify a vehicle state. An apparatus identifies a vehicle state and includes a controller connected with an angular velocity sensor and an acceleration sensor, where the controller acquires acceleration per unit time along a vehicle's longitudinal direction axis from the acceleration sensor, determines acceleration variation over a certain period of time, acquires angular velocity per unit time around vehicle's roll axis from the angular velocity sensor, determines the angular velocity variation during the certain period of time, and identifies the vehicle as a first state when the acceleration variation is greater than a first threshold value and the angular velocity variation is greater than a second threshold value, and identifies the vehicle as a second state when the acceleration variation is less than the first threshold value and the angular velocity variation is less than the second threshold value, and outputs the identified result.

摘要： The present disclosure provides a vehicle light fixture system capable of controlling an optical axis of a vehicle light fixture, without preparing a dedicated light source. A vehicle light fixture system including: circuitry configured to detect a position of a masking target object present in front of a vehicle; set, based on the position of the masking target object, a non-illumination area in which the masking target object is not illuminated; control the vehicle light fixture unit to illuminate an illumination area other than the non-illumination area; store in advance a position of a reference spot pattern that is formed, on a screen disposed ahead of the vehicle, by light emitted from the vehicle light fixture unit installed on the vehicle, in a state in which an optical axis is aligned with a designed optical axis; calculate a misalignment amount; and store the misalignment amount.
