Detailed description of preferred embodiments

The validation system for a vehicle in the present application is used to perform a validation process on a new vehicle or one or more new parts of interest. The new part may be hardware or software. The application may validate the operating conditions of the new vehicle in the validation process, or check whether the new part is exploiting its characteristics in different modes of operation of the vehicle, or promptly detecting a potential failure.

The validation system for a vehicle in the application relates to the establishment of communication between the vehicle that is subjected to the validation process (hereinafter referred to as validating vehicle) and a background control station, whereby a developer of the vehicle can receive, by the background control station, the data collected on the vehicle. In addition, the developer may send a control command from the control station to the vehicle to be validated to regulate the operation of the vehicle or the part of interest at all times.

The validation system for a vehicle in the application comprises a data collection unit and a data transfer unit, which are data-transmitting connected to each other. The data collection unit receives, through an associated sensor, the desired data of the vehicle, and the data transmission unit wirelessly transmits the data available from the data collection unit to the background control station (such as a background control station server) to provide an interconnected service to the control station enable. The data collection unit and / or the data transfer unit can be designed as software modules or means of MEMS (Micro Electro-Mechanical System).

In a preferred embodiment, the validation system for a vehicle in the application includes a connectivity control unit (CCU) of the vehicle into which the data collection unit and the data transfer unit are integrated. For example, the data collection unit and the data transfer unit are each a module in the connectivity control unit of the vehicle.

The vehicle's connectivity control unit is connected via a vehicle data bus to other functional elements, detectors, and controls of the vehicle to effectively monitor the various parts of the vehicle, wirelessly transmitting the monitoring data to the background control station (eg, a server of the Background control station), and thus at the control station to achieve an interconnected service for the vehicle. For example, for the user-driven vehicle, the connectivity control unit of the vehicle may provide calling emergency services, managing the fleet, predictive navigation, fault diagnosis, suggesting maintenance and notification of violations, and so on. Therefore, the vehicle's connectivity control unit can significantly increase safety and comfort for the vehicle.

In the present application, the "connectivity control unit of the vehicle" is understood to mean any control unit installed in the vehicle and capable of transmitting data between the vehicle and the background control station without being limited to a particular, existing connectivity control unit of the vehicle be.

In the embodiment of the application in which real-time data transmission is achieved by a connectivity control unit in the validation process, the validation system for a vehicle in the application may be referred to as an interconnected validation system for a vehicle.

The vehicle to be validated may be a road vehicle or off-highway vehicle, each having different operating characteristics that can be measured with the measuring means in the application.

For a road vehicle, its historical journey data is recorded. The data collection unit or the connectivity control unit tracks the position and movement of the vehicle (eg, the speed and acceleration of the vehicle) through a vehicle positioning system using a mobile communication system (eg, GSM) or satellite positioning system (eg, GPS). etc. may include.

However, for an off-road vehicle (eg, excavator), the positioning information that can be provided by the vehicle positioning system is likely to be insufficient, since its range of motion is very low during normal work. Therefore, an additional motion sensor must be installed in the off-road vehicle to obtain the information about the actual historical driving data of the off-road vehicle.

In addition, after logging in, the historical vibration data of a road vehicle or off-road vehicle may also be detected. For some evaluation (eg, fatigue test), vibration of a part of the vehicle, such as the exhaust system or the suspension, is very important. In the prior art (including the existing connectivity control unit of the vehicle), in a validation process for a vehicle, the real-time transmission of the measurement data of the vibration has not yet been achieved. In the application, it is proposed that the vibration sensor be arranged on the vehicle part on which the measurement of the vibration is required in order to obtain additional information about the current operating conditions.

Of course, it is necessary for certain vehicles to monitor their movement and vibration at the same time. For this, both a motion sensor and a vibration sensor must be mounted, so that the size of the movement (translation and / or rotation), speed, frequency, acceleration (vibration / impact), period, total number of movements, etc., of the part be recorded.

It should be understood that historical data can also be measured from other parameters of the vehicle.

Hereinafter, some concrete examples of the application will be described with reference to the embodiments shown in the figures.

1 shows a Erdaushubmaschine, which serves as an example of the off-road vehicle according to the invention and is combined with the validation system for a vehicle according to the invention. The excavator includes a body, which is mainly a driver's cab 1 and a power plant 2 includes and on a track device 3 mounted such that the body is rotatable about a vertical axis, and the track device 3 the back and forth movement of the vehicle allows. A big arm 4 is pivotally mounted on the body. A small arm 5 is on the big arm 4 swivel mounted. A shovel 6 is on the little arm 5 swivel mounted. The movements that the individual parts of the excavator can reach are in 1 denoted by arrows.

The excavator includes a connectivity control unit 10 and some sensors 20 , The sensors 20 are in different positions on the vehicle, such. B. on the body, the big arm 4 , the little arm 5 and the shovel 6 , The sensors 20 may include motion sensors, the back and forth movement of the entire vehicle, the rotational movement of the track device 3 as well as the swivels of the big arm 4 , the little arm 5 and the shovel 6 detect. In addition, the sensors can 20 Also include vibration sensors, those on the big arm 4 , the little arm 5 , the shovel 6 or even detect shocks or vibrations applied to the bodywork. The sensors are connected to the connectivity control unit 10 data transmitting connected. It should be noted that if the shocks or vibrations of these parts need not be detected, the vibration sensors may be omitted, so that only the motion sensors are used to detect the entire excavator and its parts.

Information about the long haul movements of the excavator (eg, from a warehouse belonging to the excavator owner, to a construction site, or from a construction site to another construction site, etc.) may be obtained by the vehicle positioning system. The daily movements of Erdaushubmaschine at a specific site, z. As the back and forth movements between an excavation point and a transport wagon are achieved by the motion sensors on the body of Erdaushubmaschine.

According to a possible embodiment, the sensor or the sensors comprises 20 on the body of the excavator, a motion sensor and / or vibration sensor incorporated in the connectivity control unit 10 (such as in 1 shown schematically), preferably in the form of a MEMS agent. For yourself within the connectivity control unit 10 The sensor can be the connectivity control unit 10 through a connection line (in the form of hardware or software) the acquired data is received directly from the sensor.

In contrast, the sensors 20 that attach to other parts of the excavator and thus outside the connectivity control unit 10 be commercially available conventional sensors. Of course, the sensors with low cost, eg. As cost-effective MEMS sensors are used, if they only serve this validation process for a vehicle.

The sensors 20 outside the connectivity control unit 10 be with the connectivity control unit 10 wired or wireless, such as. B. connected by Bluetooth or WiFi, so that the parameters detected by the sensors to the connectivity control unit 10 can be transmitted.

In the connectivity control unit 10 becomes a wireless data transmission unit 11 integrated. The detected by the sensors and by the connectivity control unit 10 received parameters are transmitted by the data transmission unit 11 is sent as historical driving data and / or vibration data of the vehicle and / or the vehicle part to the background control station and recorded in the server of the control station, so that the developer of the vehicle at the control station can receive and treat the parameters real time.

For the newly developed part or parts in the vehicle to be validated (ie part / parts of interest) Sensors are specifically designed for the validation process.

For example, it can be assumed that the newly developed part is the blade 6 a digger and the properties of the blade 6 confirmed by the validation process. Thus, motion sensors and / or vibration sensors may be located at appropriate positions of the blade 6 to be ordered. As another example, it may be assumed that the newly developed structure is a pivotal connection structure between the blade 6 and the little arm 5 is a Erdaushubmaschine and the properties of the Schwenkverbindungsstruktur be confirmed by the validation process. Thus, motion sensors and / or vibration sensors may be located at appropriate positions of the blade 6 and / or the little arm 5 to be ordered. The data collected by the sensors specifically intended for the validation process of the newly developed part is provided by the connectivity control unit 10 received and through the data transmission unit 11 sent as historical trip data and / or vibration data of the part of interest to the background control station and recorded in the server of the control station, so that the developer of the vehicle at the control station can receive and handle the parameters of the part of interest in a real time.

For a road vehicle can use a technology similar to that in 1 As shown embodiment, a validation system for a vehicle be designed. Of course, as mentioned above, the road vehicle may obtain the historical running data of the vehicle only by the vehicle positioning system.

It should be noted that for many vehicles (road vehicle and off-road vehicle) vibration could be an important factor in the failure or fatigue of a part. Therefore, in the validation system for a vehicle, vibration sensors are arranged in the application at the part of interest or the neighboring parts.

The background control station is configured to receive the data of the relevant vehicle or vehicle part in real-time from the data transmission unit or connectivity control unit to store, evaluate, and handle the data as a series of continuous historical data. According to a possible embodiment, in the background control station, the data from a vehicle or vehicle part having a same type as the vehicle to be validated or the vehicle part to be validated is compared with each other real-time or regularly. For example, the data from different vehicles (of equal or dissimilar models), users and / or conditions of use may be compared to determine the characteristics of the vehicle or vehicle part more quickly and efficiently.

All sensors in the validation system for a vehicle can be taken after the validation process has been completed. However, only some of the sensors may be removed after the validation process while the others remain in the vehicle for further use. Of course, all sensors can remain in the vehicle for further use after the validation process.
