Definitions
- the invention relates to a sensor arrangement according to the preamble of claim 1
- DE 43 43 474 A1 discloses a sensor device for detecting the degree of wetting and / or contamination of panes.
- a transmitter emits radiation to the inside of a pane. The rays are between the outer surface and the inside surface of the pane Multiple total reflections and finally recorded by a radiation measuring device.
- a heating device is used which heats the pane to a certain temperature. Snowflakes which are deposited on the pane can also be thawed by heating the pane and the resulting water can then be detected
- the object of the present invention is to ensure the functional reliability in the case of a sensor arrangement of the type mentioned at the outset, even in the case of adverse external environmental conditions This object is achieved by the features mentioned in claim 1
- a central idea of the invention is then to provide a heating device on or in the outer sensor surface, which is arranged on the outside of a vehicle.
- deposits such as ice, frost, snow or slush on the outer sensor surface can be removed Heating the sensor surface makes it possible either to prevent such deposits to prevent build-up in adverse environmental conditions or to melt existing coverings or to cause them to slip by melting away on the surface
- the heating device is connected to a control device which acts on the heating device in dependence on input signals. act a temperature signal on the sensor or the sensor outer surfaces or a signal which indicates the degree of contamination or covering of the sensor or the sensor outer surface.
- a control device which acts on the heating device in dependence on input signals. act a temperature signal on the sensor or the sensor outer surfaces or a signal which indicates the degree of contamination or covering of the sensor or the sensor outer surface.
- other or additional input parameters can also be used to control the heating device
- the sensor outer surface has a sensor-specific function and is therefore part of the sensor in the narrower sense.
- the sensor-specific part can be a heated radar lens
- the heating device can be switched on permanently while driving or from a "ignition on” signal, depending on the driving speed, depending on the outside temperature or depending on an am Sensor measured temperature take place.
- the selected operation will depend on the function of the sensor.
- a switch-on and switch-off hysteresis can be stored be, so that the heating device is switched on, for example, from a certain first temperature signal and off a second defined temperature signal
- the operation of the heating device while driving can also be selected differently depending on the application.
- the heating device can be operated, for example, with constant power or else variably. With a variable control, the heating power can depend, for example, on the driving speed or a temperature signal
- the heating can also be operated as a function of a contamination or coating signal.
- a contamination or coating signal can be obtained either from the sensor signal from the sensor itself or from an additional sensor that senses the state of the transmission and / or reception surfaces
- the sensor arrangement comprises, in addition to the receiver, a transmitter for emitting signals, the reflections of which are received again by the receiver.
- the signals in each case pass completely through one or more sensor surfaces
- the arrangement of a heating device is expedient in the case of sensor arrangements which have sensor outer surfaces on the outside of the vehicle.
- Such systems represent, for example, the parking aid, a distance control system or other driver assistance systems or a pre-crash detection system.
- the type of signals used is also not restricted in the case of the present invention emitted and received signals can be, for example, ultrasound, infrared or radar signals. Depending on the type of signals used, it is only necessary to ensure that the emitted and received signals are not falsified by the heating device
- the heating device can be designed in the form of a heating foil, integrated heating wires, a resistance layer, printed heating conductors or simply applied heating wires
- the present invention is explained in more detail below with reference to an exemplary embodiment and with reference to the only accompanying drawing.
- the single drawing shows a sensor arrangement according to the invention of a distance control system in a vehicle
- the distance control system which is not shown in full, comprises a sensor arrangement 10 with a transmitter 12 and a receiver 14, each of which is connected to a control and evaluation unit 16.
- the transmitter 12 is designed to emit radar signals.
- the receiver 14 detects the radar signals and reflected from a preceding object outputs correspondingly generated signals to the control and evaluation unit 16, which determines a distance value from the radiated and received radar signals and outputs this via an output line 17 to further (not shown) units of the distance control system
- a component of the sensor arrangement is a sensor outer surface 18, which acts as a cover for transmitter 12 and receiver 14, which acts (not visible) as a radar lens and is arranged on the front outside of the vehicle.
- the sensor outer surface 18 is arranged in a recess in vehicle body 21 and held and suitable for radiation with and bundling radar beams.
- the sensor outer surface 18 can also be designed as a component of the body
- 18 heating wires 20 are attached to the outer side of the sensor outer surface, which are connected to a control device 24 via conductors 22.
- the control device 24 receives input signals, in this case a signal terminal 15 (terminal 15), the vehicle speed signal v and an outside temperature signal T Alternatively, other input signals can also be used
- heating wires 20 are energized when the vehicle is in operation (Kl 15 signal) and a certain combination of vehicle speed v and outside temperature T is present Power controlled as a function of the driving speed v and the outside temperature T.
- the algorithm stored in the control device 24 is empirically determined in such a way that ice, frost or snow or slush on the sensor surface 18 is reliably prevented in all driving and environmental situations
- one or more tables can be stored in the control device 24, which output an associated electrical power in accordance with the input signals
- a signal about contamination or an already existing coating on the sensor surface 18 can also be provided as an input signal for the control device 24.
- a signal can come from the sensor arrangement, in particular via the control and evaluation device 16 itself, or via an additional sensor be determined
- the present invention ensures the functional reliability of a sensor arrangement with a sensor surface, which is arranged on the outside of a vehicle, in a simple manner even under adverse environmental conditions and thus contributes to increased comfort and safety
