摘要： PROBLEM TO BE SOLVED: To change a light distribution pattern of a vehicle lamp in such a manner that a mental strain more than necessity may not be applied to a driver while running a vehicle of which the vehicle lamp is lit, for a light distribution- controlling system for the vehicle lamp. SOLUTION: When the light distribution pattern for a lamp group is changed while the vehicle of which the lamp group is lit runs, the main control circuit of the light distribution-controlling system for the vehicle lamp notifies the change of the light distribution pattern (a step 116) prior to performing the illumination by the light distribution pattern determined by the step 112 (a step 118). Therefore, the driver can grasp when and how the light distribution pattern for the lamp group 10 is changed beforehand, and does not need to always keep the change of the light distribution pattern for the lamp group 10 in mind. Thus, the mental strain more then necessity can be avoided from being applied to the driver. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To reliably and easily prevent giving glare to a preceding car and favorably secure a visual field of a driver by a system for controlling light distribution of a lighting fixture for a vehicle. SOLUTION: A main control circuit of this system calculates first a reference lower limit speed Vmin according to a type of a road where the vehicle travels at a step 114. If an average speed V of the vehicle is at the reference lower limit speed Vmin or higher, distribution of lamps is determined by a standard mode (step 118). If the average speed V is below the reference lower limit speed Vmin, distribution of the lamps is determined such that the lamps give little glare to the preceding car comparing with the standard mode (step 120). After determining whichever distribution, the main control circuit outputs a signal indicating the determined distribution to a distribution control circuit (step 122) which controls light distribution of the lamps on the basis of the distribution indicating signal.

摘要： PROBLEM TO BE SOLVED: To change light distribution for a light distribution control system of a lighting fixture for a vehicle without giving a driver a sense of incongruity even when the vehicle is running on a climbing road and a sloped road. SOLUTION: A main control circuit of the light distribution control system of the lighting fixture for the vehicle calculates an inclination of a traveling road at a step 112 while the vehicle is running and controls light distribution by selecting either mode based on the calculated inclination. When the traveling road is a plain road, light distribution control by a normal mode is practiced at a step 116. When the traveling road is a climbing road, light distribution control by a climbing road mode is practiced at a step 118 and light distribution of a group of lamps is switched at timing which is later than that of practice of light distribution control by a normal mode. When the traveling road is a sloped road, light distribution control by a sloped road mode is practiced at a step 120 and light distribution of a group of lamps is switched at timing which is earlier than that of practice of light distribution control by a normal mode.

摘要： PROBLEM TO BE SOLVED: To avoid continuity of unsuitable light distribution control as much as possible by detecting abnormality by a normal control circuit in the case that the abnormality occurs in a light distribution determination control circuit or a lighting fixture control circuit in a light distribution control system of a lighting fixture for a vehicle. SOLUTION: A main control circuit of the light distribution control system of the lighting system for the vehicle determines light distribution of a lamp group when the vehicle reaches a required light distribution control area, and transmits previously announcing data displaying contents of the determined light distribution control to a lamp control circuit. When the vehicle travels on the required light distribution control area, control data displaying the determined light distribution pattern or the like are repeatedly transmitted to the lamp control circuit. The lamp control circuit stores them when the previously announcing data are received (step 214), and when the control data are received, the abnormality of the main control circuit is detected by collating the contents of the previously announcing data with light distribution control instructed by the control data.
