摘要:
An apparatus is provided to control an angle of a light axis of light from headlights mounted on a vehicle. In the apparatus, images of a field of view in front of the vehicle are captured, and the captured images are used to detect taillights of a preceding vehicle. A illumination target position is set by using, as a positional reference, a position of the detected taillights in the captured images, and the angle of the light axis so that the light axis is directed to the illumination target position. The command is provided to an angle changing device, where the provided command depends on the angle calculated. The angle changing device changes the direction of the light axis of the light at an angle commanded by the command.

A vehicle headlight apparatus receives road data from a navigation system. The apparatus has a first and a second swivel devices for adjusting an optical axis directions of a main light and a sub-light corresponding to one and the other headlights of a right and a left headlights, respectively. The apparatus also has a control unit, which separately controls the first and the second swivel devices, so that a one-eye navigation-cooperated control operation can be carried out which adjusts only the optical axis direction of the main light to be coincident with a road direction calculated based upon the road data.

In a method of phase adjustment for the demodulator 1 of the present invention, the phase adjustment is performed by driving any one of the heaters on the two waveguides 10 and 11 in the Mach-Zehnder interferometer (MZI) 6 and on the two waveguides 14 and 15 in the MZI 7. In case that an initial phase difference between the MZIs 6 and 7 smaller than a required phase difference as π/2 therebetween, the heaters C and D are driven, that are formed on the first waveguide 10 in the MZI 6, and the heaters G and H are driven, that are formed on the second waveguide 15 in the MZI 7. In case that the initial phase difference is larger than the required phase difference (π/2) therebetween, the heaters A and B formed on the second waveguide 11 in the MZI 6, and the heaters E and F formed on the first waveguide 14 in the MZI 7 are driven.

A discharge lamp ballast. Its starting means comprises a second inductor connected between a first end of a discharge lamp and the positive voltage side of a first capacitor; a second capacitor forming a resonance circuit together with the second inductor; a second switching element connected between the positive terminal of a DC power source and the second end of the lamp; a third switching element connected between the second end of the lamp and the negative voltage side of the first capacitor; and a starting control means that controls both switching elements. The starting control means alternately turns both switching elements on and off so as to contribute resonance voltage of the resonance circuit for starting of the lamp in case of the starting mode. According to the invention, noise from the starting means can be reduced.

A control unit of a vehicular headlamp apparatus can selectively perform steering angle control and navigation-cooperative control. The steering angle control operates a drive mechanism based on a steering angle and a speed of a vehicle to control a headlamp's swivel angle. The navigation-cooperative control operates the drive mechanism using a navigation unit to control the swivel angle. When a current position of the vehicle reaches an entry control start point, the control unit starts navigation-cooperative control at the entry into a curved road. The control unit finds a target swivel angle based on a curvature radius and curved road direction information about the curved road. While the vehicle moves from the entry control start point to a curved road start point, the control unit operates the drive mechanism to gradually change the headlamp's swivel angle to the target swivel angle.

An automatic vehicle headlight beam direction adjustment system, able to learn early of errors in front road information from a navigation system and eliminate continued adjustment of the beam directions of headlights in a mistaken direction, which makes the beam directions of the left and right headlights swivel for adjustment in the left-right directions parallel to a horizontal direction based on an estimated swivel control angle calculated in accordance with a speed and front road information, determines that there is an error in the estimated swivel control angle and cancels swivel advance control when the beam directions are not the direction of advance of the vehicle regardless of the vehicle running straight after the swivel advance control has continued for a predetermined time after operation of the steering wheel, and can therefore prevent swivel advance control from continuing over a predetermined time due to error of the front road information and quickly restore advance visibility of the driver.

A member communication system which includes a radio base station connected to an exchange for establishing a communication interface with a mobile terminal such as a car telephone set where the number of output carriers of a modulation apparatus to be inputted to an amplification apparatus is controlled so as to be decreased in response to failure of an amplification circuit or circuits so that an increase in intermodulation distortion is eliminated and the necessity for each amplification circuit to have a superfluous saturation output is eliminated, thereby reducing power consumption. In the mobile communication system, the radio base station includes a modulation apparatus including a plurality of modulation circuits for outputting carriers different from each other, an amplification apparatus including a plurality of amplification circuits connected in parallel to each other, failure supervision apparatus for supervising a failed condition of the amplification circuits of the amplification apparatus, and an output carrier number control apparatus, for controlling the number of output carriers of the modulation apparatus in response to amplification circuit failure information detected by the failure supervision apparatus.

In a parking lock control device of a vehicle of the present invention, when a parking lock activation command is outputted, either one of parking lock mechanisms is activated. In this state, a movement of the vehicle is estimated or detected, and when the vehicle movement is a predetermined amount or more, the parking lock control device generates a torque that suppresses the vehicle movement by the motor connected to the other parking lock mechanism. Power consumption associated with the parking lock is then suppressed.

In a parking lock control device of a vehicle of the present invention, when a parking lock activation compound is outputted, either one of the parking lock mechanisms is activated. When the steering wheel is steered to a right hand side, the left side parking lock mechanism is activated. When the steering wheel is steered to a left hand side, the right side parking lock mechanism is activated. Thus, power consumption is suppressed. In a case where the vehicle moves when only the one parking lock mechanism is activated, the other parking lock mechanism is also activated.
摘要:
In order to suppress power consumption, in a parking lock control device of a vehicle of the present invention, when a parking lock activation command is outputted, either one of right or left parking lock mechanism is activated. When it is estimated or detected that the vehicle moves in a state in which only the one parking lock mechanism is activated, the other parking lock mechanism is activated.
