Definitions
- the invention relates to sensor devices which for optically supported detection of operating gestures or
- Operating actions can be used on motor vehicles and a method for operating the sensor device.
- the invention relates to sensor devices, which record and evaluate temporally and spatially resolved information to detect the user's request to operate.
- pixels which receive optical information in parallel, for example in the form of a CCD array.
- DE 10 2008 025 669 A1 discloses an optical sensor which detects a gesture, whereupon a closing element of a vehicle is automatically moved.
- WO 2008/116699 A2 relates to an optical sensor chip and relates to an optical anti-pinch device for monitoring a windowpane, sliding door or tailgate in a motor vehicle.
- WO 2012/084222 A1 discloses an optical sensor for actuating and monitoring a closing element.
- gesture control in various technical areas is becoming increasingly accepted, attempts have also been made to use such purely optical systems for detecting the desire to operate in motor vehicles. However, these systems continue to have control over capacitive systems.
- Invention is used.
- the invention relates to a sensor device which uses the time of flight (TOF) method, so that this will be briefly explained here.
- TOF time of flight
- the TOF method is a space area with a
- Illuminated light source and the duration of the reflected back from an object in the space area reflected light from the light source back to a surface sensor This should be
- Light source and sensor to be arranged as close to each other.
- the required duration of the light is directly proportional to the distance. From the linear relationship between the time of light and the speed of light, the distance between
- the light source is pulsed in this concept.
- the detection unit that is to say the pixel array, is switched pulsed sensitive, ie the
- Integration window of the individual pixels is synchronized with the time of the light source and in the integration period
- this collection method is not a purely image-based acquisition method. It is determined at each pixel distance information, which by the temporal Light detection takes place. Finally, when using a pixel array, there is a matrix of distance values that allows for cyclic detection interpretation and tracking of object motion.
- a contact with a terminal outside the motor vehicle can for example by doing
- control circuit is designed according to the invention
- Receive data from a Bluetooth terminal and provide the control circuit, the control circuit to do so is configured to process the received data and to adjust the firmware and / or settings in the memory based on the data.
- Control circuit is adapted to receive data from the Bluetooth interface. Finally, it must be ensured that the received data can also be processed, i. the control circuitry must be configured to process the received data and to adjust the firmware and / or settings in the memory based on the data. Just one
- the Bluetooth interface constantly tries to communicate with further in-vehicle Bluetooth interfaces
- Bluetooth interfaces are provided and one
- Wiring harness is provided.
- the sensor device has a uniform circuit board for the pulse light source
- the detection area 3 of a 3D camera in the sensor device is directed downwards, away from the vehicle. This 3D camera is intended to be the
- a gesture with his foot which is recognized as an operator gesture and triggers an opening or closing of the tailgate of the vehicle 1.
- the sensor device 1 which includes, inter alia, a Bluetooth interface
- a Bluetooth terminal 4 is indicated, with which data can be transmitted to the sensor device or received from this.
- the Bluetooth terminal may be a smart phone, a tablet or similar Bluetooth enabled devices ⁇ act.
- the tailgate is opened or closed.
- the driver circuit 14 in turn is coupled to a control circuit 15, which also includes the
- the light-sensitive detection chip 16 drives.
- the detection chip has a pixel array of 30x30 pixels in this embodiment. Such a pixel matrix is for observations of
- Control circuit 15 based on these data settings and / or adjust the firmware of the control circuit, which is stored in a memory 15b. Based on the adjusted firmware and / or adjustments, the control circuitry may process the data received from the light-sensitive detection chip and determine if there is an operator gesture.
- the Bluetooth interface 17 may also be wholly or at least partially formed on the board 11. Furthermore, the sensor device may include an auxiliary control circuit 18. Using this auxiliary control circuit, or with the help of the control circuit of the 3D camera, the
- Communication authorization of the Bluetooth terminal 4 are determined. This can be done, for example, via the wiring harness Information can be provided by means of which it can be determined whether the Bluetooth terminal is authorized to send data to the control circuit. Only if this is confirmed, the data can be sent and, if necessary, an adjustment of
- Control device of the motor vehicle of the control circuit communicates the MAC addresses of such Bluetooth terminals, which may communicate with the sensor device and / or those that are not allowed to communicate with the sensor device or should (for example, further in-vehicle Bluetooth interfaces,
- Bluetooth terminal a predetermined or programmed Bluetooth PIN code is entered. If the code is entered correctly for both interfaces (the
- Interface of the sensor device can be coupled. If the link key is lost, a new authentication is necessary.
- the pulsed light source 13 together with the acquisition chip 16 defines an optical axis 20.
- a marker light source 21 is formed in the embodiment shown in FIG.
- the marker light source 21 is a powerful light emitting diode.
- the marking light source 21, the detection chip 16 and the pulse light source 13 thus lie within a unitary housing 10 and on a common board 11 along an optical axis 20.
- the marker light source 21 is also arranged adjacent to the terminals 12.
- Lead plates 22a, 22b supply the operating voltage of the marker light source 21.
- An associated driver circuit 23 is coupled to the leads 22a, 22b and to the circuit 15, which also coordinates the switching on of the marker light source.
- the proposed arrangement is a compact, uniform sensor device with a 3D detection and marking of an operating area. Since the components are housed together with a housing and are permanently aligned with each other, installation on the vehicle is particularly simple and reliable.
