Embodiment Construction

[0043] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 It is a schematic diagram of an important part of a motor vehicle to which the system of the present invention is applied. Headlamps HL are respectively arranged on the left and right of the front part of the automobile, and these headlamps HL are each equipped with a plurality of control mechanisms for changing and controlling light irradiation patterns such as light irradiation directions. In this embodiment, as the control mechanism, a horizontal adjustment device for controlling the vertical deflection of the light axis of the headlamp HL, a rotating device for controlling the horizontal deflection of the optical axis of the headlamp, and It is a cleaning device for removing sludge and dust adhering to the front lens of the headlamp. which is, figure 1 A schematic cross-sectional structure of the left headlamp HL is shown. A lamp body 11 and a transparent fron...

Abstract

According to an example embodiment of the invention, a vehicle headlamp system includes a headlamp having multiple control devices, and an ECU configured to control the control devices respectively. Each of the control devices is configured to control and change a light irradiation condition of the headlamp. The ECU (100) stores vehicle constants, error code information and initialization information corresponding to different types of vehicle respectively, and controls the control devices with a plurality of control mechanisms such as a leveling device (5) and a rotating mechanism (4). When a vehicle type is changed, the ECU selects at least one of the vehicle constants that corresponds to the changed vehicle type, clears the stored error code information and the initialization information after selecting the one or more vehicle constants, stores initialization information that corresponds to the changed vehicle type in accordance with the selected vehicle constant(s), and initializes the control devices in accordance with the stored initialization information. The ECU is configured to recognize dependencies between the control devices and, if the control devices include a first control device that is independent, the ECU executes a normal control by the first control device directly after initializing the first control device.

Description

Technical field [0001] The present invention relates to a headlight of a vehicle such as a motor vehicle, and more particularly, to a headlight system for a vehicle having a function of automatically changing and controlling the light irradiation pattern of the light irradiation direction of the headlight. Background technique [0002] In recent years, as one of the purposes of improving the driving safety of motor vehicles, a headlamp system capable of appropriately automatically controlling the light irradiation direction of the headlamp has been proposed. For example, there is a system that includes: a level adjustment device having a change in the inclination angle of the motor vehicle (the inclination angle in the front-rear direction of the motor vehicle) caused by the change of the occupant of the motor vehicle and the loaded cargo. The function of controlling the light irradiation direction to change in the vertical direction; the rotating device has the function of track...
