- monitoring the vehicle it is also possible to monitor any external To reliably identify and characterize influences, acting events or influences on the vehicle in order to be able to record, for example, vehicle abuse or improper use of the vehicle, e.g. in the form of very light to severe impact or impact events. Accordingly, the
- Invention also a reliable accident detection of the vehicle.
- An acceleration sensor and / or a gyro sensor and / or an acoustic sensor that detects noise can be provided as the sensor element.
- Known triaxial acceleration and / or angle sensors can preferably be used.
- the sensor device can be a sensor for determining the position or location of the vehicle, e.g. a GPS or GNSS receiver, by means of which position data of the vehicle provided by a "Global Positioning System” (GPS) or “Global Navigation Satellite System” (GNSS) can be received.

- the communication element enables wireless communication of the
- Sensor device with the external computer, e.g. as a cellular network module through a radio link over a cellular network.
- the recorded sensor data can be temporarily, regularly or continuously transferred to the external computer, regardless of the vehicle position.
- the recorded sensor data can not only be comprehensively evaluated with a high computing power, but also the results of the evaluation can be made available to third parties, for example an owner, user, lessor or insurance provider of the vehicle.
- the sensor data recorded or transmitted by the sensor device enables an essentially complete picture or a complete history of the respective driver's handling of the vehicle or of events which act on the vehicle from the outside.
- anomalies i.e. for the
- Vehicle status as events to be critically assessed are those events which lead to premature wear of one or more Can guide vehicle components, such as chassis components such as dampers or springs.
- Critical events that do not directly impair functionality or are not visible from the outside can also be identified
- the sensor device is preferably designed as an independent of the respective vehicle electronics, e.g. to a chassis, chassis or body component of the
- the sensor device therefore does not have to use vehicle-internal communication systems, but generates the driving data via its own sensor system.
- the sensor device is therefore largely independent of its actual installation position or position in the respective vehicle
- the device can independently determine or find its position or spatial orientation in the vehicle or the position or orientation of an existing vehicle coordinate system based on its own initialization algorithm and an empirically predeterminable starting pattern.
- the raw sensor data are read out continuously and regularly and buffered.
- the raw data recorded within an empirically predeterminable time window are preprocessed, it being checked whether an also empirically predeterminable threshold value is exceeded and thus a possible event influencing the determination of the state of the vehicle component is present.
- the threshold value can be determined on the basis of an empirical, specially parameterized data model, wherein the data model can be based on physical parameters or other vehicle parameters.
- a sleep mode is activated and the process is carried out again. If a possible event is recognized, a possibly
- the present sleep mode is deactivated and a check is made to determine whether a relevant event has occurred. If this is the case, the temporarily stored raw data of the affected time window are called up and transmitted to an external computer. If no relevant event is recognized, then so-called zero data is generated for the affected time window and transmitted to the external computer. This null data can e.g. with a brief information "No event", together with a time window corresponding to the time slot concerned
- Timestamp. Zero data generated in this way is characterized in particular by a relatively small data size or data volume compared to the originally recorded sensor data.
- sensor data read out during an active sleep mode are first temporarily stored in a buffer memory and that the sensor data stored in the buffer memory is used to ensure that the predetermined threshold value is not exceeded of a relevant event to restore the previous time interval.
- the proposed method thus represents a continuous, closed process, which ensures that the raw data supplied by the sensor system at least in every operating phase of the vehicle, i.e. in particular also in a resting phase of the vehicle, are recorded and transmitted to the external computer.
- the proposed procedure thus enables the incoming and thus
- Computationally intensive data analysis does not have to take place in the sensor device, but can be carried out on an external computer.
- the sensor device merely preprocesses the acquired sensor data in order to filter out irrelevant or redundant data components for the subsequent, externally carried out data analysis and thus to minimize the data traffic via the mostly existing mobile radio network.
- the method is carried out continuously or continuously, i.e. also during standstill or parking phases of the vehicle, and not only when the vehicle is in operation or when it is being driven.
- the raw sensor data can still be encrypted by the sensor device before said intermediate storage within the sensor device or at least before it is sent to the external computer, in order to ensure sufficient data security for the possibly personal usage data of the vehicle.
- the advantages of the proposed sensor device and the proposed method could lie in the fact that an accurate and comprehensive acquisition, processing and analysis of the acquired sensor data is made possible.
- a complete usage or mechanical load history can be created for a specific vehicle, which can include a wide variety of events in the product life cycle. These events can be of importance for the value of the vehicle, the mechanical state of certain, actually localized vehicle components and the Traceability and the severity of mechanical damage to the vehicle caused by vehicle abuse or vehicle accidents.

- Vehicle outer skin component or vehicle tires are Vehicle outer skin component or vehicle tires.
- the creation or creation of a complete digital vehicle history also enables the owner of a vehicle to track every kilometer driven in the vehicle history with regard to the events experienced, e.g. Track damage cases, driving styles and / or in each case runway surfaces. For these events, the associated position data can also be evaluated and thus a possible correlation with existing conditions, e.g. Road conditions. Based on the resulting information, a relative
- Vehicle wear can be determined.
- this information can e.g. can be statistically evaluated relative to a representative vehicle type or a representative user group.
- relative vehicle wear can also be related to a statistical comparison group of a vehicle fleet. This enables user-group-specific evaluations as well as evaluations of the relative residual value losses of the vehicles under consideration due to the different vehicle wear determined.
- Vehicle damage that is not visually recognizable but can lead to premature wear or failure of components can be recognized. This means that vehicle abuse can also be made transparent, e.g. for a car rental company, a leasing company or an insurance company can be qualified and quantified before the vehicle is inspected. Other advantages could e.g. through improved support from

- the invention can be used in industrial fields, e.g. used in the conveyor technology used in ore mining to monitor the mechanical condition of the transport rollers used there. It should be emphasized that the role monitoring is very time-consuming and therefore costly due to the conveyor belts, which often extend over many kilometers.

- Vehicle electronics can be operated independently and is at most supplied with electrical voltage via the vehicle's on-board electronics.
- chassis components e.g.
- Damper legs or wheel carriers structural body parts arranged in the engine compartment of a vehicle or surrounding structures of a suspension strut bearing, or installation locations near a vehicle battery, an OBD2 interface, in or on a center tunnel or on the vehicle structure in a spare wheel well.
- Sensor device takes place either via the connection to the vehicle battery (via ring cable lugs on battery poles), or via the OBD2 interface or an integrated battery pack. It is also possible to install the sensor device in a control unit of a (semi) active suspension system, steering system or steering actuator (steering gear), a wheel or axle carrier or a braking system.
- a control unit of a (semi) active suspension system, steering system or steering actuator (steering gear), a wheel or axle carrier or a braking system In particular, the two processes shown in FIG. 2 are implemented in the microcontroller 115 to carry out the service routine 140 mentioned. Firstly, the wake / sleep routine 200 shown on the left-hand side of FIG. 2
- Preprocessing process of the initially still raw sensor data 205 In order to operate the wake / sleep routine 200, raw data is continuously read out by the acceleration sensor 120 in every driving state of the vehicle.
- the preprocessing routine 205 divides the raw data acquired in this way into empirically predeterminable time windows At, and in each of these time windows a statistical evaluation is carried out by the preprocessing routine 205, on the basis of which event detection 215, 230 takes place. On the basis of the event recognition, decision logic 220, 235 is used to identify whether a relevant event is present, on the basis of which the wake / sleep routine is switched from a sleep mode to an active mode. On
- the wake / sleep routine is based on the following basic process conditions:
- the sleep mode is always activated when no event has been detected for an empirically predetermined period At id
- An empirically predeterminable threshold value can be used as the basis, an event being recognized only when it is exceeded.
- the sensor element that detects the at least one mechanical variable e.g. an acceleration sensor of the sensor module 120 active.
- the acceleration sensor continuously supplies the microcontroller with measurement data.
- the sleep mode is deactivated and further process routines are started (“active mode”).
- FIGS. 3a and 3b show two different examples of acquired raw data from the acceleration sensor.
- a predetermined threshold value is used on the basis of a sufficiently high signal strength
- measurements can be made by the sensor module 120
- Acceleration data are not buffered directly in the flash memory 130 of the device 100, but first in a smaller buffer memory (not shown). If an acceleration or an acceleration pattern, e.g. B. due to a
- an initial critical event e.g. a collision with another vehicle or obstacle. This ensures that the information required for data analysis and correct classification of a critical event is not lost even when the sensor module is in sleep mode.
- Sensor data is preferably sent to the cloud 110 only when the sensor module is fully active and the vehicle is in active operation (“active mode”). Therefore, an empirically predeterminable threshold value can also be formed around the sensor device or the microcontroller 1 15 either wake up or put into sleep mode accordingly.
- An empirically predeterminable time threshold value can be formed for switching to sleep mode, which switches the sensor module to sleep mode in the event of events that are not recorded in a defined time interval.
- FIGS. 4a-4c show the preprocessing of raw data from an acceleration sensor and a gyro sensor in greater detail.
- FIG. 4 a in the upper three lines 400 the acceleration data a x , a y and a z continuously supplied in the three spatial directions and in the lower three lines 405 the gyro or position data g x continuously supplied in the three spatial directions.
- g y and g z using the time format "hh: mm: ss"
- the preprocessing process maps defined time windows At onto the signal profiles which overlap in time, the time window At 410 being shown enlarged in FIG. 4b in the example.
- the three signal curves 415 of the raw data highlighted in dashed lines each have relatively large amplitudes, so that an empirically predetermined threshold value is exceeded at least for a short time.
- the data record contained in this time window At 410 which is formed from the six measured variables a x , a y and a z as well as g x , g y and g z , becomes complete and includes the respective time stamp in the preferably non-volatile data memory shown in FIG. 1 130, for example a flash memory, is stored or buffered.
- time windows i.e. Time windows with a signal curve contained therein, which exceeds the empirically predetermined threshold value, must be fundamentally distinguished from the detection of a complete event.
- a time window can now randomly contain a complete event, as shown in FIG. 4b.
- complete events extend e.g. Impact events, over several time intervals At.
- further analysis steps are required.
- Waveforms 420 are not sufficient to exceed said threshold.
- the information “no event” is present in the flash memory 130
- step 510 the raw data is preprocessed, in which step 515 it is checked whether the raw data has exceeded the predetermined threshold value within the predetermined time window At 410 and thus a possible event is recognized. However, if the threshold value is not exceeded in step 515, ie no event is detected, then the sleep mode becomes step 520 activated or continued, if necessary, and jumped back to the beginning of the routine to step 500.
- step 515 If a possible event is recognized in step 515, then the sleep mode is deactivated in the subsequent step 525 and a check is subsequently carried out 530 to determine whether there is a relevant event at all. It should be noted that, alternatively, it can already be recognized in step 515 whether there is also a relevant event. If this is the case, then in the subsequent step 535 the temporarily stored 505 raw data of the affected time window At 410 are called up, written into the internal data memory (flash memory) and transmitted 540 to the external computer from the presence of a predefinable number of stored data packets in step 520, the sleep mode is reactivated and the program jumps back to step 500.
- the internal data memory flash memory
- time ranges than the present time range At 410 can also be called up in which changes have been detected.
- all those time intervals At which have exceeded the threshold value are preferably called up. From these time windows, a subsequent one in the external computer, e.g. in the cloud 110, incoming to be performed
- the overall event can be extracted and characterized or classified.
- step 533 If, however, no relevant event is recognized in step 530, “zero data” called in step 533 is generated, this zero data is stored in the internal data memory and then transmitted to the external computer.
- the entire routine shown in FIG. 5 thus represents a continuous, closed process, which ensures that the at least one of the
- Accelerometer delivered raw data in every operating phase of the vehicle, i.e. especially when the vehicle is at rest, recorded and sent to the external
