Vehicle lamp system

A vehicle lamp system comprising:

• an illuminance variable lamp capable of performing adjustment such that illuminance of any region of an angle of view of a vehicle camera mounted on a vehicle is different from illuminance of another region;
• and
• a lamp control unit capable of controlling the illuminance variable lamp,
• wherein after acquiring, from a vehicle control unit configured to control the vehicle, position information of a low accuracy region where a recognition accuracy of the angle of view of the vehicle camera is equal to or less than a predetermined value, and first recognition accuracy which is the recognition accuracy of the low accuracy region at that time, the lamp control unit is configured to execute the following (1) and/or (2):
• (1) controlling the illuminance variable lamp so as to increase the illuminance of the low accuracy region, and acquiring, from the vehicle control unit, second recognition accuracy which is the recognition accuracy of the low accuracy region in this state,
• in a case where the first recognition accuracy is higher than the second recognition accuracy, controlling the illuminance variable lamp so as to decrease illuminance of the low accuracy region with respect to illuminance when the first recognition accuracy is acquired, and
• in a case where the second recognition accuracy is higher than the first recognition accuracy, controlling the illuminance variable lamp so as to increase the illuminance of the low accuracy region with respect to the illuminance when the first recognition accuracy is acquired,
• (2) controlling the illuminance variable lamp so as to decrease the illuminance of the low accuracy region, and acquiring, from the vehicle control unit, second recognition accuracy which is the recognition accuracy of the low accuracy region in this state,
• in a case where the first recognition accuracy is higher than the second recognition accuracy, controlling the illuminance variable lamp so as to increase illuminance of the low accuracy region with respect to illuminance when the first recognition accuracy is acquired, and
• in a case where the second recognition accuracy is higher than the first recognition accuracy, controlling the illuminance variable lamp so as to decrease the illuminance of the low accuracy region with respect to the illuminance when the first recognition accuracy is acquired.

A vehicle lamp system comprising:

• an illuminance variable lamp capable of performing adjustment such that illuminance of any region of an angle of view of a vehicle camera mounted on a vehicle is different from illuminance of another region;
• an illuminance fixing lamp capable of emitting light with a specific illuminance toward a region including the angle of view of the vehicle camera;
• and
• a lamp control unit capable of controlling the illuminance variable lamp and the illuminance fixing lamp,
• wherein after acquiring, from a vehicle control unit configured to control the vehicle, position information of a low accuracy region where a recognition accuracy of the angle of view of the vehicle camera is equal to or less than a predetermined value, and first recognition accuracy which is the recognition accuracy of the low accuracy region at that time, the lamp control unit is configured to execute the following (3) and/or (4):
• (3) controlling at least one of the illuminance variable lamp and the illuminance fixing lamp so as to increase illuminance of the low accuracy region, and acquiring, from the vehicle control unit, second recognition accuracy which is the recognition accuracy of the low accuracy region in this state,
• in a case where the first recognition accuracy is higher than the second recognition accuracy, turning off the illuminance fixing lamp and/or controlling the illuminance variable lamp so as to decrease illuminance of the low accuracy region with respect to illuminance when the first recognition accuracy is acquired, and/or
• in a case where the second recognition accuracy is higher than the first recognition accuracy, turning on the illuminance fixing lamp and/or controlling the illuminance variable lamp so as to increase illuminance of the low accuracy region with respect to illuminance when the first recognition accuracy is acquired,
• (4) controlling the illuminance variable lamp so as to decrease the illuminance of the low accuracy region, and acquiring, from the vehicle control unit, second recognition accuracy which is the recognition accuracy of the low accuracy region in this state,
• in a case where the first recognition accuracy is higher than the second recognition accuracy, turning on the illuminance fixing lamp and/or controlling the illuminance variable lamp so as to increase illuminance of the low accuracy region with respect to illuminance when the first recognition accuracy is acquired, and/or
• in a case where the second recognition accuracy is higher than the first recognition accuracy, turning off the illuminance fixing lamp and/or controlling the illuminance variable lamp so as to decrease illuminance of the low accuracy region with respect to illuminance when the first recognition accuracy is acquired.
