Definitions
- the invention relates to a device for detecting obstacles in the area of movable flaps that close and/or release a volume, in particular in motor vehicles.
- overlaps is to be understood below in particular as electrically closable tailgates of motor vehicles, but also vehicle doors, engine hoods and other movable surfaces for closing or releasing a volume.
- the mentioned device is not only limited to motor vehicles or only suitable, but can be used in all means of transport.
- a generic device for detection is known from DE 10 2014 015 031 B4.
- the optical signals sent by a transmitting device and received by a receiving device ensure a very reliable detection of obstacles in the movement or pivoting range of the flap possible contact of the flap with the obstacle takes place, so that even with a mechanical overrun of the flap there is still sufficient time or distance available to stop the movement of the flap.
- the device is characterized in that the number of transmitting devices is greater than the number of receiving devices, and the transmitting devices and the receiving device/s are arranged in relation to one another in such a way that at least one receiving device can receive the optical signals from more than one of the transmitting devices.
- the device according to the invention has the advantage that fewer receiving devices, in particular sensors or, for example, infrared (IR) sensors, are required than transmitting devices, for example IR LEDs. This reduces the number of sensors and thus the costs for manufacturing the device.
- IR infrared
- a further advantage of the device lies in the possibility that one or more transmitting devices can be placed between the receiving devices and can thus be used jointly by the receiving devices. This increases the efficiency of the transmission devices and reduces the power consumption of a detection device compared to the prior art.
- the number of control devices can be reduced, so that at least one control device is necessary and each sensor-LED pair no longer has to be controlled or supplied with a control device, as is known from the prior art .
- the number of transmitting devices is preferably between one and a half and five times greater, preferably between two and three times greater than the number of receiving devices.
- At least two transmitting devices are arranged between two adjacent receiving devices. This can be the case for one, several or all neighboring receiving devices.
- the transmitting devices and/or the receiving devices are advantageously spaced apart in time and can be activated or controlled in a specific sequence. This can reduce the peak power consumption of the device as well as the peak amount of data produced when registering reflected signals at a time.
- control device is designed to communicate with the transmitting devices and/or the receiving devices via an internal bus system, in particular via a custom bus system or a UART bus system, and to output or receive signals to the transmitting devices and/or the receiving devices. to be received by the transmitting devices and/or the receiving devices.
- control device is preferably designed to communicate with a vehicle-side bus system, in particular a CAN bus system, and to output signals to the vehicle-side bus system or to receive them from the vehicle-side bus system.
- vehicle-side bus system in particular a CAN bus system
- the transmitting devices are designed to emit optical signals, in particular infrared, visible light and/or UV light, which can be received or registered by the receiving devices.
- Visible light has the advantage that it can also be used for lighting.
- a more precise distance determination and obstacle detection can be carried out. Short-wave signals are more accurate when determining position or distance, but have a shorter range due to scattering and attenuation.
- the transmitting devices and the receiving device(s) are preferably arranged on a line, in particular on a straight line. With the help of this arrangement, the device can be made space-saving or thin in its width. At the same time, the device extends the longest in length (compared to another device with the same number of transmitting and receiving devices) and can check a longer frame (of the flap) for obstacles and thus secure it. It has been shown to be advantageous if the transmitting devices are always at a first distance from an adjacent transmitting device and the receiving devices are always at a second distance from an adjacent receiving device. In other words, the distance from neighboring transmitting devices and the distance from neighboring receiving devices of a device is always constant. On the one hand, the regular arrangement can simplify the manufacturing or installation process. Furthermore, a uniform recognition or detection of obstacles over a region of the device is possible.
- the second distance is greater than or equal to the first distance.
- This has the advantage that at least two transmitting devices are available for a receiving device. This can also influence the sensitivity of the device when detecting obstacles.
- two transmitting devices can be placed between two receiving devices.
- the second distance is preferably twice as large as the first distance.
- two transmission devices can be arranged between each two adjacent receiving devices, in particular symmetrically or asymmetrically to the middle of the distance between the receiving devices. Due to the different distances between the transmitting device and the neighboring receiving device, foreign bodies are irradiated with light at different angles and are better able to block them. As a result, foreign bodies are also better detected in the "scissor area" of a flap.
- the device has a switching device that is designed to provide a connection, in particular an electrical connection, between the control device and the receiving devices and to control one or more receiving devices.
- the switching device can receive the signals from the control device and send them selectively to the corresponding receiving device.
- the switching device can receive, in particular call up, the signals from the receiving device and send them to the switching device.
- the switching device and its functions mentioned above are particularly advantageous if the control device uses a general broadcast switching technology (or similar) and does not have an explicit receiver for the signals to the receiving device. used. In the event that the control device can selectively control the receiving devices or is designed in such a way that it takes over the aforementioned functions of the switching device, the switching device becomes redundant and can be omitted.
- the control device and/or the switching device are preferably designed to control or activate at least one of the transmitting devices and at least one of the receiving device(s) according to a specific temporal and/or spatial pattern. Activations of the transmitting and/or receiving device, in particular simultaneously and/or one after the other, with different or the same time intervals can be understood under a time pattern.
- a spatial pattern is, for example, the activation of every second, third or nth transmitting and/or receiving device.
- patterns can be used in which only transmitting devices or only receiving devices are activated.
- at least one counterpart of the corresponding device/s should be activated in order to register an obstacle or to determine the freedom of movement of the flap using the device.
- control device and/or the switching device are preferably designed to determine and/or control at least two groups, each of which has one of the receiving devices and at least one of the transmitting devices, in such a way that the groups when sending and receiving optical signals do not or only partially influence each other.
- groups when sending and receiving optical signals do not or only partially influence each other.
- the transmitting devices and the receiving devices are advantageously arranged in relation to one another in such a way that at least two groups, each of which has one of the receiving devices and at least one of the transmitting devices, can be determined and these groups do not or only partially influence each other when transmitting and receiving optical signals.
- the broadcast Devices of the respective groups are spaced apart from receiving devices in other groups in such a way that these receiving devices cannot receive any signals or signals that can be identified by these transmitting devices.
- the or certain transmitting devices which are arranged between two adjacent receiving devices and/or neither fall below nor exceed a certain distance value range from the respective receiving devices belong to two groups at the same time. This makes it possible for one or more receiving devices of the respective group to be able to receive an optical signal from these transmitting devices. This leads to partial mutual interference or crosstalk on the receiving devices when activating the transmitting devices.
- the range of distance values describes the set of different distance values from one or more transmitting devices to the closest receiving device in their own group and in the other groups that can receive the signal.
- the distance between one of the transmitting devices or the respective distance from at least some of the transmitting devices to their group of associated receiving devices is preferably smaller than a distance between two adjacent receiving devices.
- the device according to the invention preferably works on the principle of light reflection, with the light originally radiating out from the transmitting device and the reflection being received or registered by the receiving device.
- the transmitting and receiving devices are not (only) arranged next to one another, but rather face each other in such a way that a receiving device receives the light of a transmitting device directly.
- the comparison of the received optical signals can in particular with a respective position of the flap corresponding optical target signal suc conditions.
- These target signals can, for example, based on the reflection with the Flap frames to be closed are predetermined, with the reflection becoming stronger as the distance between the flap and the frame decreases.
- IR sensors and LEDs In addition to IR sensors and LEDs, other optical sensors and LEDs can also be used that emit visible light and can therefore be used as lighting means.
- the transmitting and receiving devices can each be arranged on their own line or straight line. Likewise, the transmitting devices can be arranged around one or more receiving devices, in addition to or as an alternative to the linear arrangement.
- transmitting and receiving devices By intelligently activating the transmitting and receiving devices, which is to be understood as an example of a temporal and/or spatial pattern, crosstalk between the transmitting devices is avoided. Only one transmitting device is active during the measurement of a receiving device. The distance between two active pairs of transmitting and receiving device/s is selected in such a way that they do not affect each other.
- the switching device of the device can also be designed to provide a particular electrical connection between the control device and the transmission devices and to control one or more transmission devices.
- the switching device can receive the signals from the control device and selectively send them to the corresponding transmission device, in particular activating it.
- the switching device has the advantage that instead of all transmission devices being activated simultaneously and/or always, they can be activated selectively, in particular according to a specific temporal and/or spatial pattern.
- the control device can be designed in such a way that it fulfills this function.
- the control device can have a stored program that is automatically executed after activation by an external bus system and controls the transmitting and receiving devices in a specific way in order to detect an obstacle. If groups of transmitting and receiving devices can be determined and/or controlled in such a way that they partially influence each other, this means that the signals from at least one transmitting device are received or can be received by at least two receiving devices from two different groups.
- the transmission device emits modulated optical signals.
- the modulated optical signals can be pulse width modulated and/or frequency modulated, which enables the optical signals to be detected very easily and reliably.
