Definitions
- the invention relates to an object control and/or regulation system, comprising an object, a target direction detection device for detecting at least one target movement variable, an evaluation unit and an alignment unit for the object. It also relates to a device for illuminating the roadway, as well as a two-wheeler or three-wheeler and a method for object control and/or object regulation.
- Cornering lights that depend on the driving situation have become standard in motor vehicles and ensure increased safety.
- the cornering light can be controlled as a function of a curve radius being driven, a yaw rate or a lateral acceleration of the vehicle, or it can be coupled to a navigation system which allows predictions to be made about the type of road being traveled on.
- a headlight mounted on the driver's helmet can illuminate the target direction well, but small head movements disturb the constantly rapidly changing headlight direction and other road users are strongly dazzled.
- the weight of the headlight and the rechargeable battery supplying the headlight with electrical energy must be carried on the driver's head.
- DE 10 2005 036 002 A1 discloses a headlight system for a vehicle driven by an operator with at least one controllable and adjustable headlight for emitting a light beam dependent on the viewing direction, with at least one adjustment device connected to the adjustable headlight, by means of which the adjustable headlight can be adjusted, and with a detection device that detects the direction in which the operator is looking.
- the invention is based on the object of specifying a robust, reliable and precise system for controlling and/or regulating, in particular alignment, of an object. Furthermore, a device for illuminating the roadway, a two-wheeler or three-wheeler and a corresponding method are to be provided.
- a reference detection device for detecting at least one reference movement variable, the evaluation unit being configured in such a way that, based on the at least one detected target movement variable and the at least one detected reference movement variable, it generates at least one signal for controlling and/or regulating the object and transmits it to the alignment unit, the alignment unit being configured to align the object on the basis of this at least one signal.
- the invention is based on the idea that the illumination of the roadway, especially when turning, is also very important for cyclists and e-bike riders. Cycle paths are often in poor condition, curve radii are much tighter than can be anticipated, and the paths are poorly lit. tet. In comparison to country roads, there is usually no white line at the edge of the road. Signposts on cycle paths (white signs with green writing) are placed at a height that makes it impossible for the driver to read them with a conventional bicycle headlight. There is also a need in other areas of application to align an object in a targeted manner.
- motion variables are determined both from an object and from a reference and the difference between these variables is used to control and/or regulate the object.
- the target direction detection device and the reference detection device each have a transmitting and/or receiving unit for wireless communication, in particular by means of BLE (Bluetooth Low Energy).
- BLE Bluetooth Low Energy
- ANT(+), ZigBee/RF4CE, RFM, WiFi or a comparable wireless transmission standard can also be used instead of BLE.
- These forms of communication have the necessary range and at the same time consume little energy, so that the battery or rechargeable battery rarely has to be changed.
- a transmission standard for longer ranges at the expense of the energy requirement is also conceivable.
- An object direction and/or object acceleration and/or object speed is preferably recorded as a target movement variable, with a reference direction and/or a reference acceleration and/or a reference speed advantageously being recorded as the reference movement variable. If, in addition to the directions, the accelerations, in particular also the acceleration due to gravity, are also recorded, the inclination of the object and/or the reference frame can also be taken into account, for example when using the system for aligning a headlight.
- an object direction and a reference direction are detected, with the evaluation unit generating a signal for controlling and/or regulating the object from the difference between the two detected directions. In this way, errors caused by the Movement acceleration of the target direction detection device arise to be compensated.
- the target direction detection device advantageously has a sensor for the earth's magnetic field
- the reference detection device advantageously having a sensor for the earth's magnetic field to detect the reference direction.
- any sensor that can detect and process translational and rotational movement signals is suitable.
- the consideration of the earth's magnetic field serves in particular to correct the possible deviations in the movement acceleration.
- the system is configured as a headlight system for a vehicle driven by an operator, with an object configured as a controllable and adjustable headlight for emitting a light beam dependent on the viewing direction, with an alignment unit configured as an adjustment device connected to the adjustable headlight, by means of which the adjustable headlight can be adjusted, with a target direction detection device configured as a gaze detection device, which detects the operator's line of sight, and with a reference detection device configured as a position detection device, which the position of the vehicle and/or the target direction detection device and/or the headlight is detected.
- a target direction detection device configured as a gaze detection device, which detects the operator's line of sight
- a reference detection device configured as a position detection device, which the position of the vehicle and/or the target direction detection device and/or the headlight is detected.

- the absolute or relative angle of the head movement is preferably determined from the two sensor signals, from which the signal for controlling and/or regulating the object is then generated.
- the headlamp system includes two sensors on the helmet in order to also record the direction of view and head movement. These sensors are located on the helmet on the sides above the ears. The angle of the head movement is determined from these two sensor signals. Since the sensors move in opposite directions when the head moves, the absolute or relative angle of the head movement or the absolute or relative position of the head can be determined from the two sensor signals in order to adjust the vehicle lamp with this value.
- no sensor is then required on the bicycle or the lamp, ie the difference between the sensors on the helmet and the bicycle is not determined, only between the sensors on the helmet.
