Abstract: Light from a headlight is prevented from being diffusely reflected on a road surface and reaching an oncoming vehicle. Provided is a lamp control method of controlling a lamp including a lamp unit that projects light over a predetermined range and a driver that turns on and turns off or dims a light projection range of the lamp unit in predetermined units. The lamp control method includes a step of obtaining a reflection region on a road surface where the light projected from the lamp unit is regularly and diffusely reflected by the road surface and reaches a driver of an oncoming vehicle or a preceding vehicle, and a step of controlling the driver so that the light projected onto the reflection region from the lamp unit is turned off or dimmed.

Abstract: To provide light distribution control technology for a vehicle lamp capable of improving driver visibility.
A vehicle lamp control apparatus that controls light irradiation state of a vehicle lamp capable of irradiating light forward of a vehicle, where the light irradiation state is controlled such that, when a vehicle speed is lower than a reference value, a road surface illuminance due to light from the vehicle lamp at a first forward distance which is close to the vehicle becomes a first value; when the vehicle speed is greater than the reference value, the road surface illuminance due to light from the vehicle lamp at the first forward distance becomes a second value which is smaller than the first value; and the road surface illuminance due to light from the vehicle lamp at a second forward distance which is far from the vehicle becomes substantially constant regardless of the vehicle speed.

Abstract: 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.
