Abstract: A steering wheel is determined to be under a counter steering state when the following two conditions are both satisfied: (I) a steering angle measured with a steering angle sensor is equal to or greater than a predetermined angle; and (II) a steering direction does not coincide with a turning direction of the vehicle. The vehicle is determined to be under a slipping state when the following two conditions are both satisfied: (I) the steering angle is equal to or greater than the predetermined angle; (II) an absolute value of a change per unit time of a difference between a left wheel speed and a right wheel speed is equal to or greater than a predetermined value. Under both the counter steering state and the slipping state, adjustment of the optical axes of the swivel lights is stopped or modified.

Abstract: In a headlight optical axis adjusting apparatus and method for a vehicle, the shape of a road in front of the vehicle is detected by a CCD camera based on a change in lane marking line which indicates the lane width on the road, before the steering angle of a vehicle steering wheel is detected by a steering angle sensor. Left and right swivel lights of the vehicle are swiveled and adjusted based on the change in the lane marking line or the steering angle. The optical axis of the left or right swivel light is first swiveled and adjusted based on the change in the lane marking line. The driver's forward visibility can thus be improved before the driver turns the steering wheel.

Abstract: The present invention changes the headlight optical axis of a vehicle in relation to an inclination angle during normal control and to properly adjust the optical axis according to information including front information about a car ahead. The headlight optical axis is adjusted based on the inclination angle of a vehicle, road information in the direction of travel, presence of a car ahead, a distance between vehicles, and the center optical axis angle corrected according to changes in horizontal and vertical behavior of the car ahead.

Abstract: A forward condition detecting apparatus for vehicles has a laser radar device mounted on a vehicle. A front height sensor and a rear height sensor detect a front height and a rear height of the vehicle, respectively. An electronic control unit calculates an angle of inclination of the vehicle relative to a reference plane based, on a difference between the detected front height and rear height. The electronic control unit then calculates a laser beam radiation angle based on the calculated angle of inclination. The electronic control unit controls an angular position of the laser radar device based on the calculated radiation angle so that the laser beam may be maintained leveled generally in parallel with the reference plane irrespective of the inclination of the vehicle. The laser radar device is preferably mounted in a vehicle front headlight unit to be driven together with a headlight lamp.

Abstract: The rear vehicle height HR is detected by the vehicle height sensor as vehicle inclination information by a CPU. Based on the rear vehicle height HR, the inclination angle of the headlight optical axis direction is computed with an inherent control constant corresponding to vehicle specifications preset by a specification discrimination signal. Then, the headlight optical axis direction is adjusted with reference to the pitch angle.

Abstract: In a vehicle headlight optical axis automatic adjusting system, a pitch angle in the longitudinal direction of a vehicle is calculated from a signal of a height sensor. Filtering corresponding to a control mode according to the acceleration is fixed and is not frequently switched unless the constant speed state of the vehicle continues for a predetermined time. The pitch angle may be calculated on the basis of the vehicle rear height value by using a prediction expression which is divided into a plurality of regions of vehicle postures according to loading conditions of an occupant load and a trunk load in correspondence with the vehicle type. The pitch angle may be updated when the vehicle enters a constant speed driving mode, i.e., stable driving mode, so that even when one trip is not finished the error is cancelled.

Abstract: A pitch angle in the back-and-forth direction of the vehicle body is calculated based on output signals of height sensors disposed at front and rear wheels of the vehicle. A vehicle traveling speed is obtained. A vehicle acceleration is obtained from the vehicle traveling speed. Using the vehicle traveling speed and the vehicle acceleration, a judgement is made to determine the control mode corresponding to the vehicle traveling condition, by selecting one from the group consisting of a stopping mode, an acceleration mode, a deceleration mode and a constant-speed mode. An actuator target value (i.e., target aiming adjustment angle) is calculated in accordance with the determined control mode. To obtain this actuator target value, a filter is used to process the pitch angle so that the headlights do not dazzle an oncoming vehicle's driver. Then, the aiming adjustment for the headlights is performed by actuating actuators in accordance with the actuator target value.

Abstract: An apparatus according to which a sample and a reagent are mixed together at a given temperature in a colorimetric cell to enable a property of the sample to be determined in an instrument such as a photoelectric colorimeter or a spectrophotometer. The sample and reagent are initially situated in a pair of containers one of which can be enclosed entirely within the other with the inner container extending above the level of the contents in the outer container. A colorimetric cell is connected in a fluid-tight manner at its open end to an upper open top of the outer container, and then after the entire assembly and the contents of the containers are brought to a given temperature, this assembly is inverted to discharge the contents of both containers into the colorimetric cell.
