Problems solved by technology

The body axis usually deviates by an angle relative to the driving axis of the car, which is mostly less than 0.5 degrees, and in individual cases even reaches several degrees, because when using distance sensors, the sensitivity depends on correct calibration, so the way to adjust the body axis There will always be measurement errors

Embodiment Construction

[0015] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0016] The drawing shows a control device arranged at the front of the motor vehicle, including a regulator SEG for the headlights of the vehicle. The regulator SEG is constructed in a known manner, the optical system of which can basically receive the headlight light completely, it is mainly aligned with the direction of the driving axis by means of a calibration device, and the driving direction is first determined by means of the calibration device and a calculation device installed in it. The direction of the axis, but also when the vehicle is started on the test stand, for example, when the wheels have only turned one revolution.

[0017] The calibration device has a marking part, including several reference marks R on the reference mark device RA, which device is fixedly arranged relative to the detection table during the measurement proces...

Abstract

The invention relates to an adjusting device with a regulator (SEG) for a headlight or a distance sensor of a motor vehicle, comprising an optical alignment device (K1, K2, F , R, E), it is characterized in that, described optical calibration device (K1, K2, F, R, E) has a computing device, and this computing device is for measuring the direction of the driving axis during the start of the car, and also There is a marking (E) for aligning the regulator (SEG) with respect to the direction of the driving axis.

Description

technical field [0001] The invention relates to an adjusting device with an actuator for a headlight or a distance sensor of a motor vehicle, comprising an optical alignment device for aligning the actuator relative to the motor vehicle. Background technique [0002] Such an adjusting device is disclosed in German patent document DE 197 07 590 A1. In this known device, an adjuster for a radar distance sensor adjusts the vehicle body to the axis of symmetry via a direction-finding unit. The axis of the body is usually deviated by an angle relative to the axis of travel of the car, which is mostly less than 0.5 degrees, and in individual cases even reaches several degrees, because when using distance sensors, the sensitivity depends on the correct calibration, so the way to adjust the axis of the body Measurement errors always occur. To calibrate the regulator, the sensor signal is transmitted in the form of a radar signal to a flat reflector placed at a distance in front of...
