## Abstract

A vehicle system, in a vehicle that travels around a corner by tilting a vehicle body toward a turning direction, includes a light source, an optical member configured to form a predetermined light distribution pattern including a plurality of regions formed in parallel in one direction by irradiating a front side of a lamp with light from the light source, a sensor configured to detect a lamp position of an object outside the vehicle, and a control unit configured to determine an upper end position of the object based on the lamp position, and to adjust the predetermined light distribution pattern such that among the plurality of regions, a first region including the upper end position is not irradiated with the light.

## Claims

### Claim 1

A vehicle system provided in a vehicle that travels around a corner by tilting a vehicle body toward a turning direction, the vehicle system comprising:
a light source;
an optical member configured to form a predetermined light distribution pattern including a plurality of regions formed in parallel in one direction by irradiating a front side of a lamp with light from the light source;
a sensor configured to detect a lamp position of an object outside the vehicle; and
a control unit configured to determine an upper end position of the object based on the lamp position, and to adjust the predetermined light distribution pattern such that among the plurality of regions, a first region including the upper end position is not irradiated with the light.

### Claim 2 (depends on 1)

The vehicle system according to claim 1, wherein
the object is a vehicle mounted with a pair of lamps arranged at both left and right sides at a certain distance, and
the control unit is configured to:
calculate an interval between the pair of lamps based on the lamp position, and
calculate the upper end position by multiplying the interval by a predetermined constant.

### Claim 3 (depends on 1)

The vehicle system according to claim 1, wherein
the plurality of regions are vertically elongated regions arranged in parallel in a left-right direction.

### Claim 4 (depends on 1)

The vehicle system according to claim 1, wherein
the light source includes a plurality of light emitting elements arranged in parallel,
the plurality of regions are formed in parallel along a horizontal direction by light from the plurality of light emitting elements, and
the control unit turns off the light emitting element forming the first region among the plurality of light emitting elements based on the upper end position.

### Claim 5 (depends on 1)

The vehicle system according to claim 1, wherein
the optical member includes at least one of a rotation reflector, a galvanometer mirror, and a polygon mirror, and
the control unit controls a scanning direction of the light determined by at least one of the rotation reflector, the galvanometer mirror, and the polygon mirror, and an emission timing of the light from the light source, based on the upper end position, and then forms the predetermined light distribution pattern such that the first region is not irradiated with the light.

### Claim 6

A vehicle lamp provided in a vehicle capable of travelling around a corner by tilting a vehicle body toward a turning direction, the vehicle lamp comprising:
a light source;
an optical member configured to form a predetermined light distribution pattern including a plurality of regions formed in parallel in a horizontal direction by irradiating a front side of the lamp with light from the light source; and
a control unit configured to, when an object is present outside the vehicle, determine an upper end position of the object based on a lamp position of the object, and to adjust the predetermined light distribution pattern such that among the plurality of regions, the region including the upper end position is not irradiated with the light.

### Claim 7

A vehicle lamp provided in a vehicle capable of travelling around a corner by tilting a vehicle body toward a turning direction, the vehicle lamp comprising:
a light source;
an optical member configured to form a predetermined light distribution pattern including a plurality of regions formed in parallel in a horizontal direction by irradiating a front side of the lamp with light from the light source;
and
a control unit configured to adjust the predetermined light distribution,
wherein the control unit is configured to, when an object is present outside the vehicle, reduce an illuminance of light for a first region of the plurality of the regions including a lamp position of the object and a second region adjacent to the first region and closer to the vehicle to an illuminance lower than an illuminance of light for regions other than the first region and the second region.

### Claim 8 (depends on 7)

The vehicle lamp according to claim 7, wherein the control unit is configured to increase width of the second region as tilting of the vehicle increases.

### Claim 9 (depends on 7)

The vehicle lamp according to claim 7, wherein the control unit is configured to, when the object is present, adjust the predetermined light distribution such that the first region and the second region are not irradiated with the light.

### Claim 10 (depends on 7)

The vehicle lamp according to claim 7, wherein the control unit is configured to, when the object is present, adjust the predetermined light distribution such that the first region and the second region are irradiated with the light.
