Definitions
- the invention relates to a system for detecting a condition of a vehicle component of a vehicle for monitoring and assessing the integrity and traffic safety of the vehicle.
- the road safety requirements of a vehicle and its systems are usually prescribed by law through regulations and standards. Compliance with these regulations is usually monitored at certain intervals as part of an inspection by authorized personnel from an official inspection body, such as TÜV or DEKRA in Germany. The inspection of the vehicle and its systems is usually carried out on site at the approved test center. The vehicle must therefore be presented to an inspector on a regular basis.
- the system includes a server computer and a vehicle with the vehicle component.
- the vehicle has a control computer for controlling the vehicle component and for acquiring vehicle data that describe the state of the vehicle component. Furthermore, the vehicle has a data transmission device for transmitting the vehicle data to the server computer.
- the server computer is designed to receive the vehicle data and to evaluate the vehicle data. Furthermore, the server computer is designed to determine a state of the vehicle component by evaluating the vehicle data.
- the vehicle data recorded by the control computer can preferably describe states of other vehicle components.
- the vehicle data for these other vehicle components can also be transmitted from the control computer to the server computer for analysis purposes.
- the vehicle components can be active components that can record their own condition and transmit it to the control computer in the form of vehicle data.
- the control computer can query the vehicle data recorded by the active components and transmit it to the server computer.
- the vehicle components can be designed as passive components that cannot detect their status themselves. These include, for example, shafts, wishbones and other components.
- a vehicle can be authenticated by evaluating the vehicle data by the server computer, since the respective vehicle data of the vehicles depict a specific, individual behavior of each vehicle. Manipulation or falsification of the vehicle data is very difficult, since the data would have to be manipulated both on the server computer and in the vehicle itself in order to deceive the system.
- the system thus enables clear and reliable vehicle authentication, which makes falsification of vehicle data and vehicle components almost impossible.
- the server computer can be designed to, after analyzing the vehicle data, depending on the determined state of the vehicle component and/or an assembly of different vehicle components and/or the vehicle To generate command signal that is transmitted to the vehicle.
- the control computer is designed to control the vehicle component and/or assembly as a function of the command signal. In this way, certain functionalities in the vehicle can be changed or deactivated in a targeted manner.
- countermeasures can be taken, initiated by the server computer, depending on the determined state of a vehicle component and/or an assembly of several vehicle components and/or the vehicle, if this is necessary.
- the server computer can generate a status description signal, which is transmitted to the vehicle, depending on the determined status of the vehicle component and/or an assembly of several vehicle components and/or the entire vehicle.
- the state of the vehicle component and/or the assembly and/or the vehicle determined by the server computer can be displayed for a driver on a display device, for example a multimedia system.
- the system includes a data processing device which is arranged outside of the server computer and outside of the vehicle.
- the server computer can transmit the status description signal not only to the vehicle itself, but also to the data processing device.
- the data processing device provides information that characterizes a status of the vehicle component and/or the assembly and/or the vehicle.
- recommendations for necessary maintenance or information on a possible cause of the error can be provided.
- the information can be provided both for a driver or vehicle owner and for service personnel of a vehicle maintenance company or a test center.
- the information can be displayed on a PC, tablet or smartphone, for example.
- the required computing power for determining the status of a vehicle component and/or an assembly of vehicle components and/or the entire vehicle is transmitted to a server computer on a backend side of the system.
- the server computer used in the backend provides higher and usually more cost-effective computing power than if each vehicle were to evaluate the condition of its vehicle components itself.
- the vehicle data is only recorded on a client side of the system by the vehicle's control computer in the vehicle itself can be determined by their analysis distinguishable vehicle system states that can be evaluated by the server computer.
- the system enables intelligent monitoring of the vehicle and its internal systems, i.e. individual vehicle components/parts or more complex assemblies, with regard to road safety and compliance with prescribed regulations. Furthermore, the system enables an online assessment of the condition of individual vehicle components and assemblies. The system thus offers assistance in assessing the condition of a vehicle and, moreover, increases road safety by introducing countermeasures to eliminate errors or by switching off/deactivating vehicle systems.
- Messages or information relating to the condition of individual vehicle components and/or assemblies of multiple vehicle components and/or the entire vehicle or tips and recommendations can be output on a front-end page of the system on devices used by a user of the system outside the vehicle will. These include, for example, smartphones, tablets or desktop PCs.
- the user front end can also be integrated into the vehicle's multimedia system, for example.
- the Information that characterizes the condition of a vehicle component and/or an assembly and/or the entire vehicle, or other information and recommendations is displayed on a screen of the multimedia system in the vehicle.
- the status information transmitted by the server computer can also be used on the front end of the system as a basis for remote testing and acceptance of vehicles by official testers. Based on data analysis by the server computer on the backend of the system, digitized expert knowledge and continuous improvement in remote monitoring and evaluation over the life cycle of a vehicle system, reliable predictions can be made in terms of wear and tear and the likely occurrence of faults.
- the evaluation results determined by the server computer on the backend side can be used for a large number of services. These include, for example, insurance bonus systems for "good vehicle care”.
- the system can also be used by fleet management and leasing systems to assess a vehicle's value by predicting maintenance needs and to evaluate and improve the health of vehicle systems by continuously monitoring vehicles in the field.

- the control computer 220 on the client side of the system may include one or more computer processors located in the vehicle 200 .
- the control computer 220 is designed to capture all of the vehicle data from a large number of vehicle components that are required in order for the server computer on the backend side of the system to determine the roadworthiness, conformity with a requirement profile, the maintenance status, the integrity and ultimately the assess the overall safety of the vehicle.
- the vehicle data is obtained on the client side of the system from time-synchronized signals from measuring or sensor systems, for example acceleration sensors, gyroscopes, wheel speed sensors, pressure sensors, temperature sensors, torque sensors, inside the vehicle.
- the time-synchronous provision of the vehicle data for the server computer 100 can take place by providing the recorded vehicle data with time stamps, so that the server computer 100 on the backend side can correctly classify the vehicle data transmitted to it in chronological order.
- the vehicle data can be sub-filtered as raw data or already pre-processed, for example filtered or changed in some other way, or else are transmitted to the server computer 100 in compressed form for the purpose of bandwidth reduction.
- the vehicle data can be transmitted from the control computer 220 using the data transmission device 230, for example wirelessly via a defined standard (LTE, G5, etc.) to the server computer 100 on the back end of the system.
- the vehicle data can be transmitted from the control computer 220 to the back end of the system either continuously or after a previous query by the server computer 100 .

- the server computer 100 can be designed to store the transmitted vehicle data over a (longer) period of time.
- the server computer 100 can be designed in particular to create data characterizing a vehicle profile of a vehicle by evaluating the vehicle data FD stored over the period of time.
- the data characterizing the vehicle profile can contain vehicle configuration-specific data and/or user-specific data and/or wear-specific data and/or data describing a dynamic behavior of a vehicle component and/or an assembly.
- the server computer 100 thus continuously collects vehicle data transmitted by the vehicle 200, which reflects a vehicle history and from which a vehicle profile can be determined.
- vehicle data transmitted by the vehicle 200 which reflects a vehicle history and from which a vehicle profile can be determined.
- the recorded vehicle data and the vehicle profile characterizing data of a variety of vehicles 200 can be stored and updated by the server computer 100 on the backend side of the system.
