Abstract
A method of aligning an ACC-sensor on a vehicle includes the following steps: (a) arranging a reflection surface in front of the vehicle for reflecting emitted ACC-sensor rays; (b) aligning the horizontal axis of the reflection surface parallel to the rear axle of the vehicle; (c) aligning the vertical axis of the reflection surface essentially perpendicular to the longitudinal axis of the vehicle which is defined by the alignment of the front and rear axle; and (d) adjusting the ACC-sensor such that a defined or maximal fraction of the emitted rays is reflected.
Claims6
A method of aligning an ACC-sensor on a vehicle, comprising:
- arranging a reflection surface in front of the vehicle for reflecting emitted ACC-sensor rays;
- aligning a horizontal axis of the reflection surface parallel to a rear axle of the vehicle;
- aligning a vertical axis of the reflection surface substantially perpendicular to a longitudinal axis of the vehicle defined by alignment of front and rear axles of the vehicle;
- and
- adjusting the ACC-sensor so that a defined or maximal fraction of the emitted rays is reflected;
- wherein said step of aligning the horizontal axis of the reflection surface is performed by setting a distance between the rear axle and the horizontal axis of the reflection surface to be the same on both sides of the vehicle.
A method of aligning an ACC-sensor on a vehicle, comprising:
- arranging a reflection surface in front of the vehicle for reflecting emitted ACC-sensor rays;
- aligning a horizontal axis of the reflection surface parallel to a rear axle of the vehicle;
- aligning a vertical axis of the reflection surface substantially perpendicular to a longitudinal axis of the vehicle defined by alignment of front and rear axles of the vehicle;
- and
- adjusting the ACC-sensor so that a defined or maximal fraction of the emitted rays is reflected;
- wherein
- the position of the longitudinal axis of the vehicle is determined using a laser pointer, which has a leveling device and which is aligned with the rear and front axle;
- and
- the vertical axis of the reflection surface is adjusted relative to the position of the longitudinal axis.
A method of aligning a vehicle sensor relative to a travel direction of the vehicle, comprising:
- arranging a reflection surface in front of the vehicle for reflecting radiation emitted by said sensor;
- providing adapters mounted on rear wheels of the vehicle and disposed at a fixed longitudinal position relative to the longitudinal position of a rear axle of the vehicle;
- aligning the reflection surface so that the distance from the reflection surface to the adapters is the same on both sides of the vehicle;
- and
- adjusting said sensor to maximize reflected radiation detected by it.
