This light-emitting element drive control device (100) comprises: a drive logic unit (113) which performs a drive control of a switch output stage (N1, D1, L1) for dropping an input voltage (VIN) to an output voltage (VOUT) and supplying a light-emitting element therewith; a charge-pump power supply unit (a) which generates a step-up voltage (CP) higher than the input voltage (VIN); and a current detecting comparator (114) which receives a supply of the step-up voltage (CP) and the output voltage (VOUT) as power supply voltages, and generates control signals (SET, RST) for the drive logic unit (113) by directly comparing a current detection signal (Vsns) corresponding to an inductor current (IL) of the switch output stage with a peak detection value (Vsns_pk) and a bottom detection value (Vsns_bt).

A method is provided for storing light distributions of a matrix headlight system. The method includes loading, from a memory, first control data for lighting means of a first matrix light module for generating a first light distribution; feeding the first control data to a comparison module; loading, from the memory, second control data for the lighting means of the first matrix light module or for lighting means of a second matrix light module for generating a second light distribution and feeding the second control data to a comparison module. The method compares the first and second control data; stores the first control data for the first light distribution if there is a similarity or equality between the first and second control data; and linking the second control data for the second light distribution by means of a link to the control data for the first light distribution.

To realize an apparatus and a method for receiving a recognition level of an own vehicle from another vehicle and/or an infrastructure facility and performing control to improve a recognition level. A recognition level of the own vehicle calculated by another vehicle or the infrastructure facility is received, and control for improvement of a recognition level of the own vehicle is executed in accordance with the received recognition level. As the control for improvement of a recognition level of the own vehicle, any process is executed among: (a) a process of reducing a traveling speed or stopping; (b) a process of turning on a light; and (c) a process of changing transmission information from the own vehicle. As the process of changing transmission information, a process of adding, to the transmission information, vehicle location information, vehicle speed information, vehicle size information, or reference marker position information is executed.
