Description

Technical Field

[0001] The present disclosure relates to a motion recognition system for a motor vehicle and a motor vehicle having the motion recognition system. Background Art

[0002] Sensors and camera systems on vehicles are known from the prior art, which enable the vehicle owner to continuously monitor his vehicle and its surroundings via a smartphone. Thus, a 360° panoramic view around the vehicle can be viewed via a corresponding application.

[0003] In order to find the cause of vehicle damage, such as a parking collision (Parkrempler), the vehicle owner has to accidentally activate the 360° panoramic view at the right point in time, which, however, may not succeed in most cases.

[0004] Even when sensor and camera data are recorded and stored via a 360° panoramic view application, the vehicle owner has to view all the recorded sensor and camera data in order to determine the time point of damage and the cause of damage. This is, however, a very cumbersome process, which is time-consuming and unnecessarily occupies storage capacity.

[0005] In this context, DE 10 2017 215 489 A1 describes a parking collision recognition method for a vehicle being parked, on which at least one motion sensor and an environment recording system are arranged, wherein the parking collision recognition method includes: detecting the motion of the vehicle being parked via the motion sensor; when the motion of the vehicle being parked is detected, activating the environment recording system and recording environment data; performing a plausibility check on the detected motion, wherein the plausibility check includes identifying whether there is an object in the environment of the vehicle and one of the following actions: if no object is identified in the environment of the vehicle, then stopping the recording of environment data; or if an object is identified in the environment of the vehicle, then storing and / or transmitting the recorded environment data. Summary of the Invention

[0006] Against the background of the prior art, the task of the present disclosure is to describe a device suitable for enriching the prior art.

[0007] This task is solved by the features of the independent claims. The dependent claims contain optional improvements of the present invention.

[0008] Subsequently, this task is solved by a motion recognition system for a motor vehicle being parked, wherein the motion recognition system has a motion sensor designed to detect the motion of the motor vehicle being parked and a control device coupled to the motion sensor, the control device being designed to output a control signal when the motion of the motor vehicle being parked has been detected by the motion sensor. The motion sensor can be arranged in or at the roof module of the motor vehicle.

[0009] The motion recognition system can be a parking collision recognition system and / or a tilt monitoring system. A separate control device can be provided for each of the two systems, or two functions, namely the parking collision function and the tilt (sensor) monitoring, can be implemented using a single control device.

[0010] The roof module can be understood as a part of the roof of the motor vehicle or the entire roof.

[0011] For example, the motion sensor can be arranged between the outer skin and the roof lining of the roof module, which limits the roof module inwardly to the passenger compartment.

[0012] The acceleration sensor can be implemented as a 3-axis or 6-axis acceleration sensor. A 6-axis acceleration sensor is also referred to as a gyroscopic sensor.

[0013] The control device can be, for example, an electronic control unit (ECU, electronic control unit). The electronic control unit can be an intelligent processor-controlled unit, which can communicate with other modules of the motor vehicle, for example, via a central gateway (CGW), and, if necessary, form a vehicle network with a telematics device and / or an environmental sensor system via a field bus, such as a CAN bus, LIN bus, MOST bus, and FlexRay and / or via automotive Ethernet.

[0014] A motor vehicle being parked can be understood as a motor vehicle in a stationary state, i.e., its speed is 0 km / h and its engine is continuously or indefinitely shut down. Therefore, parking can be different from stopping, because the motor vehicle is in a non-ready-to-drive state when parking.

[0015] The above-described motion recognition system offers many advantages. The central position of the acceleration sensor is conducive to accurately detecting parking collisions (firstly conducive to determining the location and severity of damage). In addition, the position in the roof module offers the advantage that the deflection of the motor vehicle in the roof area during a parking collision is higher compared to being closer to the ground.

[0016] Subsequently, possible improvements to the above-described motion recognition system are described in detail, and each of these improvements, alone and / or in combination with one, several, or all of the improvements, at least enhances the advantages of the above-described motion recognition system.

[0017] The control device can be arranged in or on the roof module. This offers the advantage that the control device is arranged close to the motion sensor. Thereby, the cabling of the motion recognition system in the motor vehicle installation can be carried out without effort, and the maintenance of the motion recognition system during the operation of the motor vehicle can be carried out without effort.

[0018] The motion recognition system can include an environment recording system coupled to the motion sensor via the control device, and the control device can be designed to output a control signal to the environment recording system such that the environment recording system records environment data corresponding to the environment of the motor vehicle.

[0019] This offers the advantage that, when the motion sensor detects motion, for example in the case of a parking collision and / or triggered by the inclination of the motor vehicle, (sensor) data can be detected and optionally stored by the environment recording system, which allows determination of the cause for triggering the motion recognition system.

[0020] The environment recording system can include a camera for recording image data corresponding to the environment of the motor vehicle.

[0021] This offers the advantage that sensors already installed in the motor vehicle, such as a camera system, can be used together with the motion recognition system.

[0022] The motion recognition system can include an information output unit coupled to the motion sensor via the control device, and the control device can be designed to output a control signal to the information output unit such that the information output unit outputs an alarm signal to the environment of the motor vehicle.

[0023] The information output unit can also be referred to as an alarm system. The information output can include optical and / or acoustic (warning) signals. This offers the advantage, similar to the use of a camera, that components already installed in the motor vehicle can be used together with the motion recognition system.

[0024] The motion recognition system can include an interface coupled to the motion sensor via the control device, and the control device can be designed to output a control signal to the interface such that the interface outputs information wirelessly to an external data processing device.

[0025] The external data processing device can be, for example, a smartphone that is wirelessly connected to the motor vehicle via the interface. The smartphone can have, for example, an application provided by the manufacturer of the motor vehicle, which is designed to notify the user of the smartphone based on the received information about triggering the motion recognition unit.

[0026] Similar to the use of a camera and an alarm system, the use of an interface of a motor vehicle offers the advantage that components already installed in the motor vehicle can also be used together with the motion recognition system here.

[0027] This information may include environmental data recorded by an environmental recording system.

[0028] For example, it is conceivable that image data recorded by a camera is output to a smartphone. This can optionally be done in real time, or the image data can be streamed to the smartphone. This offers the advantage that the user of the smartphone can assess whether his intervention is required due to the triggering of the motion recognition system.

[0029] The motion sensor can be designed to detect the motion of a motor vehicle being parked as a translational motion of the motor vehicle being parked and / or an inclination of the motor vehicle being parked.

[0030] Since the sensors for tilt sensor monitoring and parking collision function meet similar requirements, especially a low static current, because both functions are active in the parked state and the resolution is similar, the same sensor can be used for both functions. In particular, the control logic or control device for the parking collision function and tilt sensor monitoring can be located in the roof module. This has the advantage that only one sensor is required, which in addition to cost savings also results in weight savings and static current savings.

[0031] The above description of possible improvement options can be implemented exemplarily in practice as follows, where this is described without limiting the present disclosure.

[0032] According to the first example, the elevation of the vehicle can be determined or identified using tilt sensor monitoring, because for example, there is an attempt to steal the wheels of the motor vehicle. As a response, an optical and acoustic alarm can optionally be output together with notifying the vehicle owner through an application installed on the vehicle owner's smartphone.

[0033] According to the second example, the vibration generated by the collision of a motor vehicle with another or other vehicles in the parked state can be determined or identified by means of the parking collision function. As a response, the customer can be notified through the application (see above), and if necessary, a video can be recorded by an external camera of the motor vehicle in order to collect evidence of possible damage occurring on the vehicle.

[0034] Furthermore, a motor vehicle is provided, wherein the motor vehicle has the above-described motion recognition system and roof module.

[0035] The motor vehicle can be a passenger vehicle, especially a car, a two-wheeled motorcycle or a three-wheeled motorcycle, or a commercial vehicle, such as a truck.

[0036] The motion sensor can be arranged in the motor vehicle centered especially with respect to the longitudinal direction of the motor vehicle and the width direction of the motor vehicle.

[0037] The above description of the motion recognition system applies equally to motor vehicles and vice versa. Description of the Drawings

[0038] Subsequently, reference is made to Figure 1 and Figure 2 to describe the embodiments.

[0039] Figure 1 The motion recognition system of the motor vehicle is schematically shown, and

[0040] Figure 2 The motor vehicle with the Figure 1 motion recognition system is schematically shown in a side view. Detailed Description of the Invention

[0041] Figure 1 and Figure 2 respectively show a Cartesian coordinate system, the X-axis of which extends from the front to the rear of the motor vehicle 100 and thus defines the longitudinal direction X of the motor vehicle. The Y-axis perpendicular to the X-axis extends in the width direction Y of the motor vehicle, such that the longitudinal direction X of the motor vehicle and the width direction Y of the motor vehicle span a substantially horizontal plane. The Z-axis perpendicular to the longitudinal direction X of the motor vehicle and the width direction Y of the motor vehicle defines the height direction Z of the motor vehicle extending from bottom to top.

[0042] Figure 1 The motion recognition system 10 is shown in the state of being installed in the motor vehicle 100.

[0043] of the motor vehicle 100 that is being parked Figure 1 The shown motion recognition system 10 includes a motion sensor 2 and a control device 3 coupled to the motion sensor, the motion sensor being designed to detect the motion of the motor vehicle 100 that is being parked.

[0044] The control device 3 is connected to the environmental recording system 4 of the motor vehicle 100, the alarm system 5 of the motor vehicle and is wirelessly connected to the smartphone 7 via the interface 6 of the motor vehicle 100 in the installed state.

[0045] The control device 3 is designed to output control signals to the environmental recording system 4, the alarm system 5 and via the interface 6 to the smartphone 7 respectively when the motion of the motor vehicle 100 that is being parked has been detected by means of the motion sensor. The motion can be a translational motion of the motor vehicle 100 triggered by a parking collision, wherein the motor vehicle 100 moves mainly in the longitudinal direction X of the motor vehicle and / or the width direction Y of the motor vehicle. In addition, the motion can be an inclination of the motor vehicle 100, for example, when one side of the motor vehicle 100 is raised.

[0046] Here, the control device 3 is designed to control an environment recording system 4 including a camera by means of a control signal output to the environment recording system 4, such that the camera records image data corresponding to the environment of the motor vehicle.

[0047] Furthermore, the control device 3 is designed to control the alarm system 5 by means of a control signal output to the alarm system 5, such that the alarm system controls optical and acoustic alarm signals emitted to the interface 6, such that the interface wirelessly outputs information (for example including image data recorded by means of the camera) to a smartphone 7 coupled to the interface 6.

[0048] The control device 3 and the motion sensor 2 are arranged substantially centered in the motor vehicle 100 in the longitudinal direction X of the motor vehicle and in the width direction Y of the motor vehicle in the installed state also in Figure 2 the roof module 1 shown therein.

[0049] The centered and relatively high arrangement of the motion sensor in the motor vehicle 100 furthermore provides the advantage that accelerations caused by parking collisions can be detected relatively simply, since the deflection is greater here compared to a lower arrangement of the acceleration sensor 2. Furthermore, only a single acceleration sensor 3 is required for tilt monitoring and parking collision recognition.
