摘要： An auto leveling apparatus which drives a motor only in case that a posture that has changed during stoppage becomes stable and the stable posture is different from the posture controlled at the last time thereby to reduce the number of operations of the motor. In an auto leveling apparatus of vehicle headlamp including a headlamp of which a light axis tilts up and down in relation to a car body by drive of a motor, a control unit for controlling the drive of the motor, a speed sensor for detecting speed, a pitch angle sensor for detecting pitch angle, and a memory for storing the pitch angle data detected by the pitch angle sensor, in which the control unit controls the drive of the motor, on the basis of the pitch angle data detected by the pitch angle sensor, so that the light axis of the headlamp has the constant inclination in relation to a road surface, the control unit controls the drive of the motor only in case that a posture (pitch angle data) that has changed once during stoppage becomes stable and the difference between its posture and a reference posture (reference pitch angle data) exceeds the predetermined value. Therefore, according to reduction of the number of operations of the motor, durability of the motor itself is improved.

摘要： An autoleveling device comprises a pair of left and right headlamps in which optical axes L are tilted in a vertical direction with respect to a body by driving operations of respective motors 10 (10L, 10R), single control means 16 for controlling the driving operations of the left and right motors 10 at the same time, a vehicle speed sensor 12, a height sensor 14 and a storage section 20 for storing pitch angle data detected by the height sensor 14, the control means 16 controlling the respective motors 10 such that the respective optical axes L have a predetermined inclination with respect to a road based on the pitch angle data thus detected, wherein the motors are driven only if a difference between the detected pitch angle and the pitch angle used for the last driving control of the motor is equal to or more than a predetermined reference value which is more than a pitch angle equivalent to a hysteresis width of each of the left and right motor driving circuits (|&thgr;2−&thgr;1|>&thgr;0). Consequently, there is no drawback that only one of the motors is driven, and both motors are always driven at the same time. Therefore, the optical axes of the left and right headlamps are always held in the same positions in a vertical direction so that a constant visibility can be guaranteed.

摘要： An automatic leveling apparatus includes a headlamp whose light axis is pivoted in a vertical direction relative to a vehicle body by an actuator 10; a control unit 16 for controlling the operation of the actuator 10; vehicle speed detection device 12 for detection of the speed of the vehicle; and pitch angle detection device 14 for detecting a pitch angle of the vehicle. When the pitch angle detection device 14 detects a pitch angle &thgr;2 while the vehicle is in a stable traveling state, the control unit 16 controls the operation of the actuator 10 in consideration of the pitch angle &thgr;2. Consequently, the actuator is prevented from being controlled on the basis of a pitch angle obtained when the vehicle stops facing downhill or in an unnatural position such as in which the wheels on one side of the vehicle are on the curb.

摘要： An automatic leveling device for automotive vehicle headlamps is described. The device automatically stops driving an actuator if the actuator is determined to be failing, while the other normally operating actuator is used to perform a leveling of the optical axis of the headlamp as close to a proper leveling as possible. In an implementation, a pair of left and right headlamps 1L, 1R have optical axes L that are tilted individually by driving left and right actuators 10L, 10R, respectively. A single control unit 16 simultaneously controls the driving of the left and right actuators 10L, 10R. A vehicle speed detection means 12, a pitch angle detection means 14, and failure detection means 20L, 20R are included. The control unit 16 controls the driving of the actuators 10L, 10R based on a detected pitch angle such that the optical axes of the headlamps stay in a certain inclined state with respect to the surface of a road, and when an actuator is determined to be failing, the CPU unit 16 stops driving the failing actuator, while driving the normally operating actuator, thereby performing a leveling of the optical axis of the headlamp as close to a proper leveling as possible.

摘要： A device for aligning an optical axis of a light source according to the change of attitude of a vehicle is described. The device is of simple construction and is positionally accurate. In an embodiment, a controller 18 performs an alignment operation according to an output signal from a vehicle height sensor 10 and an alignment command signal (PWM signal). The PWM signal has a pulse duration that has been modulated according to this operation, and the result is input to a D/A converter 20. A transistor Q of a D/A converter 20 responds to the PWM signal and performs a switching operation, and a signal accompanying this switching operation is smoothed by a charge and discharge circuit comprising resistance R1 and R2, and a condenser C. The smoothed signal is output from both ends of the condenser C to an actuator 14, and a motor 26 is driven to rotate according to the deviation between the output of a potentiometer 24 and the voltages at both ends of the condenser C.

摘要： A head lamp auto-leveling system can be used inexpensively and for a long term by reducing the frequency in the drive of actuators, and which does not arouse an unpleasant feeling in the driver. An implementation of the auto-leveling system includes head lamps whose optical axis L is tilted vertically with respect to a vehicle body by a drive of an actuator 10, a control portion 16 for controlling the drive of actuators 10, a speed sensor 12, a height sensor 14, and a memory portion 20 for storing pitch angle data detected by the height sensor 14. The control portion 16 controls the actuators 10 based on the detected pitch angle data such that optical axes L are brought into a predetermined tilted state with respect to a road surface. The control portion 16 also decides a stable vehicle posture to control (level) the drive of the actuators 10 during both stop and running states if the difference between a plurality of moving average pitch angle data (e.g., 1-second average and 3-second average) exceeds a reference value &thgr;a once, and then a state below the reference value &thgr;a is continued for a predetermined time.
