IPC: B60Q1/02
Filed: 2002-04-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide a device reducing uncomfortability by glaring by automatically controlling a headlamp and preventing forgetting of lighting at the time of starting although a driver feels glaring and a fatigue of eyes by reflecting the headlamp of the own car by a rear surface of a forwarding car in the case of stopping following the forwarding car such as waiting at the traffic signal and ultra-low speed driving during traffic jam.  <P>SOLUTION: A means for automatically controlling lighting-on or lighting-off of the headlamp of the vehicle by detecting an intensity of light at a front side of the vehicle, a speed of the vehicle and a distance from an obstacle at a front side of the vehicle and by a combination of three results of detection is adopted. Since it is considered that a difference of an individual exists in a standard for feeling the light glaring, a means that the driver himself can set a standard value is adopted. Thereby, it is reduced that the driver feels uncomfortability and fatigue of eyes caused by glaring of the light reflected by the back surface of the forwarding car and forgetting of the light-on is prevented. Confusion cannot be imparted to surrounding vehicles by unnecessary lighting-off in the case of temporary stopping or the like.  <P>COPYRIGHT: (C)2004,JPO
