Head lamp device for vehicle
First Claim
1. A head lamp device for a vehicle in which a lighting region in front of the vehicle can be adjusted in rightward and leftward directions,said device comprises:
- direction indicating signal outputting means for detecting an operation of a winker device and outputting a direction indicating signal;
steering signal outputting means for detecting a steering angle of a steering device and outputting a steering angle signal;
map information outputting means for outputting map information including road data;
present position detecting means for detecting a present position of a proper vehicle on the map; and
control means for inputting said direction indicating signal, steering angle signal, map information and information of the present position and adjusting the lighting region of said head lamp based thereon, andsaid control means selects a first control mode when said direction indicating signal is inputted;
a second control mode for adjusting the lighting region in response to said steering angle when said first mode is not selected and said present position is not found on the road data of said map information or a steering angle of said steering angle exceeds a predetermined range; and
a third control mode for adjusting the lighting region in compliance with an expectation of a forward road shape in a traveling direction of the vehicle in reference to said map information and the present position when said first and second control modes are not selected.

Abstract
A head lamp device for a vehicle in which a lighting region in front of the vehicle in a traveling direction can be adjusted in rightward and leftward directions comprises: a direction indicating signal outputting mechanism 11 for detecting an operation of a winker device and outputting a direction indicating signal; a steering signal outputting mechanism 12 for detecting a steering angle of a steering device and outputting a steering angle signal; a map information outputting mechanism 30 for outputting map information including road data; a present position detecting mechanism 32 for detecting a present position of proper vehicle on the map; and a control mechanism 10 for inputting the said direction indicating signal, steering angle, map information and information of the present position and adjusting the lighting region of the head lamp. The control mechanism 10 selects a first control mode when the direction indicating signal is outputted; a second control mode for adjusting the lighting region in response to the steering angle when the first mode is not selected and the present position is not found on the road data of the map information or a steering angle of the steering angle signal exceeds a predetermined range; and a third control mode for adjusting the lighting region in compliance with an expectation of forward road shape in a vehicle traveling direction in reference to the map information and the present position when the first and second control modes are not selected.
