[0002] A rolling chassis generally refers to a chassis or a frame that includes a drive motor and a transmission system, so that the rolling chassis can travel with its own driving force.

[0003] Typically, the vehicle body is arranged on such a rolling chassis.

[0004] The advantage of using a rolling chassis is in particular that a wide variety of possible bodywork can be provided for the rolling chassis, so that different motor vehicles can be produced efficiently.

[0005] After the body has been arranged on the rolling chassis, it must be ensured that the motor vehicle having the arrangement consisting of rolling chassis and body functions properly. Summary of the invention

[0006] The object of the present invention is to provide a design for efficiently testing a motor vehicle, wherein the motor vehicle comprises a device having a rolling chassis and a body arranged on the rolling chassis, wherein the rolling chassis comprises a plurality of first interfaces and the body comprises a plurality of second interfaces assigned to the first interfaces.

[0007] This object is achieved by means of the respective subject matter of the independent claims. Advantageous embodiments of the invention are the subject matter of the respective dependent claims.

[0008] According to a first aspect, a method for testing a motor vehicle is provided, wherein the motor vehicle comprises a device having a rolling chassis and a body arranged on the rolling chassis, wherein the rolling chassis comprises a plurality of first interfaces and the body comprises a plurality of second interfaces assigned to the first interfaces, so that in a state where the body is arranged on the rolling chassis, a corresponding connection between the rolling chassis and the body can be formed via the corresponding first and second interfaces, the method comprising the following steps:

[0009] generating first check request signals, the first check request signals representing a request for a first check on whether the corresponding first and second interfaces are correctly connected to each other so as to form a corresponding connection between the rolling chassis and the vehicle body;

[0010] outputting the generated first inspection request signal;

[0011] receiving first inspection result signals, wherein the first inspection result signals represent first inspection results of the first inspection;

[0012] Based on the first checking result, determining which connections to form;

[0013] generating second check request signals which represent a request for a second check whether components of the rolling chassis and / or the vehicle body can be correctly addressed via the determined formed connections;

[0014] outputting the generated second inspection request signal;

[0015] receiving second inspection result signals, the second inspection result signals indicating second inspection results of the second inspection; and

[0016] Based on the second check result, it is determined which components can be addressed correctly or incorrectly via the determined formed connections.

[0017] According to a second aspect, an apparatus is provided, which is configured to carry out all the steps of the method according to the first aspect.

[0018] According to a third aspect, there is provided a computer program comprising instructions which, when executed by a computer, for example by an apparatus according to the second aspect, cause the computer to carry out the method according to the first aspect.

[0019] According to a fourth aspect, there is provided a machine-readable storage medium having stored therein a computer program according to the third aspect.

[0020] According to a fifth aspect, there is provided a rolling chassis comprising the apparatus according to the second aspect.

[0021] According to a sixth aspect, there is provided a vehicle body comprising the apparatus according to the second aspect.

[0022] According to a seventh aspect, a motor vehicle is provided, comprising a rolling chassis and a body arranged on the rolling chassis and an apparatus according to the second aspect.

[0023] The invention is based on and includes the recognition that the above-mentioned object can be achieved by checking whether all connections between the rolling chassis and the vehicle body are correctly connected or formed. The invention also includes the idea of ​​checking whether all components and / or functions can be addressed via the formed connections. Here, "can be addressed" means in particular that the components or functions can be contacted or communicated with via the formed connections.

[0024] In order to check whether all connections are correctly connected, in particular a first check request signal is generated and outputted in order to perform a corresponding first check. Here, the result of the first check is described following the first check result. Based on the first check result, it is proposed to determine which connections are formed between the corresponding first interface and the corresponding second interface. In order to check whether all components or functions can be addressed, it is proposed to provide a corresponding second check. For this purpose, a second check request signal is generated and outputted in order to check the correct addressability.

[0025] The result of this second check is a second check result which indicates which components can be addressed correctly or incorrectly via the formed connection.

[0026] The testing of the motor vehicle here therefore includes checking whether all connections are correctly connected and whether all components or functions can be addressed.

[0027] This results in, inter alia, the following technical advantage: a concept for efficient testing of motor vehicles is provided.

[0028] According to one embodiment, the method according to the first aspect is a computer-implemented method.

[0029] This results in, for example, the technical advantage that the method can be carried out efficiently using a computer.

[0030] The chassis is the chassis of a motor vehicle. This means that the rolling chassis is the rolling chassis of a motor vehicle.

[0031] Carbody means the body of a motor vehicle.

[0032] In English, the term “body” or the term “top hat” can be used for the term “car body”. Therefore, instead of the term “car body”, the term “Aufbau” can also be used in German.

[0033] According to one embodiment, the term "body" or "motor vehicle body" may be interpreted broadly. Thus, according to one embodiment, the body may include, for example, one or more of the following components: motor vehicle seats, dashboards, joysticks, motor vehicle windows, motor vehicle doors, motor vehicle interior, airbags, assistance systems, cameras, human-machine interfaces.

[0034] For the purposes of this description, the upper part of the motor vehicle arranged on the chassis ("top hat") can therefore be referred to as the body. The body can thus be a component that is manufactured to such an extent that after the body has been arranged on the rolling chassis, it forms a finished motor vehicle, i.e., in particular a motor vehicle that is ready to drive, similar to a prefabricated part of a prefabricated house.

[0035] According to one embodiment, the rolling chassis includes one or more of the following components: wheels, axles, drive motors, steering gears, brakes, frames, thermal components, batteries, battery housings, sensors, in particular environmental sensors (e.g. radar sensors, lidar sensors, ultrasonic sensors, magnetic field sensors, infrared sensors, video sensors), controllers (referred to in English as “ECU” (“Electronic control unit”)), PCs (Personal Computers).

[0036] According to one embodiment, the rolling chassis can thus already be a component which is manufactured, similar to a prefabricated part of a prefabricated house, to such an extent that after the body has been arranged on the rolling chassis, a finished motor vehicle, ie in particular a motor vehicle which is ready to drive, is formed.

[0037] The rolling chassis is therefore particularly a lower component relative to an upper component (body). Thus, according to one embodiment, a finished motor vehicle, particularly a motor vehicle ready for driving, is formed by the arrangement of the upper component (body) and the lower component (rolling chassis), wherein the upper component is arranged on the lower component.

[0038] According to one specific embodiment, it is provided that body identification signals are received which indicate a body identification of the body, wherein in the third check and / or in the first check it is checked based on the body identification whether the body is admissible for the rolling chassis.

[0039] This results in, for example, the following technical advantage: it is possible to efficiently check whether the vehicle body is permissible for a rolling chassis. Permissible vehicle body for a rolling chassis means, in particular, that the vehicle body can be used together with the rolling chassis as a corresponding device in a motor vehicle.

[0040] The vehicle body identification can be used, for example, to read the vehicle body specification belonging to the vehicle body from a database in which vehicle body specifications are respectively stored for a plurality of different vehicle bodies.

[0041] Next, the third check and / or the first check is performed, for example, based on the vehicle body specifications.

[0042] Therefore, according to one embodiment, in addition to checking whether the respective first and second interfaces are correctly connected to each other, the first check also includes a further check whether the vehicle body is permitted to be used for the rolling chassis.

[0043] According to one specific embodiment, it is provided that self-test request signals are generated and output, which self-test request signals represent a request for a corresponding self-test to be carried out by components and / or functions of the rolling chassis and / or the vehicle body.

[0044] This results in, for example, the technical advantage that the motor vehicle can be tested efficiently. In particular, this results in the technical advantage that the components and / or functions can be tested efficiently.

[0045] According to one specific embodiment, it is proposed that third inspection results are generated and output, which represent third inspection results of a third inspection.

[0046] According to one embodiment, it is proposed that self-test result signals are received, which represent the results of the respective self-tests.

[0047] According to one specific embodiment, it is provided that cooperative test request signals are generated and output, which express a request for a cooperative test of components and / or functions of the rolling chassis and / or the vehicle body.

[0048] This results in, for example, the technical advantage that the motor vehicle can be tested efficiently. In particular, this results in the technical advantage that the interaction of components and / or functions of the rolling chassis and / or the body can be tested efficiently.

[0049] The coordination of components and / or functions can be, for example, as follows: Emergency Brake Assist uses the video data of the camera in order to decide whether to carry out emergency braking. In the event of a decision to carry out emergency braking, Emergency Brake Assist or an Emergency Brake Assist function implemented, for example, in a camera controller of the camera or in another controller of the vehicle body sends a corresponding emergency brake control signal to the brake or to a brake controller of the brake. In this case, the brake and the brake controller are included by the rolling chassis.

[0050] This means that the cooperation of the emergency brake assist (function) or the camera controller or the other controller (component) comprised by the vehicle body with the brake controller or the brake (component) comprised by the rolling chassis is accordingly tested.

[0051] In the exemplary cooperation just described, provision can in particular be made to test the cooperation of the emergency brake assist with a drive and / or a steering gear instead of or in addition to the brakes, wherein both the drive and the steering gear are comprised by the rolling chassis.

[0052] Then, correspondingly, for example, the emergency brake assistant sends a drive control signal to the drive or to a drive controller and / or to a steering gear or to a steering controller, wherein the drive controller and the steering controller are comprised by the rolling chassis.

[0053] According to one specific embodiment, if one of the results indicates the presence of an error, inhibition signals are generated based on this result, which indicate which components and / or functions of the motor vehicle and / or the rolling chassis and / or the body should be inhibited, wherein the generated inhibition signals are output.

[0054] This results in, for example, the following technical advantage: negative effects due to the error can be effectively prevented, at least partially prevented.

[0055] For example, it is proposed that the drive motor of the motor vehicle should be disabled. This results in, for example, the following technical advantage: the motor vehicle can be effectively prevented from being completely put into operation.

[0056] According to one embodiment, it is proposed that if one of the results indicates the presence of an error, then based on this result, restriction signals are generated which indicate which component(s) and / or functions of the motor vehicle and / or the rolling chassis and / or the body should still be used only in a restricted manner, wherein the generated restriction signals are output.

[0057] This results in, for example, the technical advantage that negative effects due to the error can be prevented, in particular at least partially prevented.

[0058] According to one specific embodiment, it is provided that if one of the results indicates the presence of an error, solution signals are generated based on this result, which solution signals represent solution suggestions for solving the problem of the presence of the error, wherein the solution signals are output.

[0059] This brings about, for example, the following technical advantage: the problem can be solved efficiently.

[0060] According to one specific embodiment, it is provided that if one of the results indicates that an error is present, a communication message is sent via the communication network to at least one network address, wherein the communication message includes information that an error is present.

[0061] This brings about, for example, the following technical advantage: the error can be notified efficiently.

[0062] The network address is assigned, for example, to a computer of a user of the rolling chassis or motor vehicle.

[0063] The network address is assigned to, for example, a user's mobile device, such as a mobile phone.

[0064] The network address is assigned, for example, to a server of the manufacturer of the rolling chassis.

[0065] The network address is assigned, for example, to a plant or a server of a plant.

[0066] The network address is assigned, for example, to a remote testing entity or external to the vehicle. Such a testing entity is, for example, the TÜV (Technical Inspection Institute) in Germany.

[0067] For example, it is proposed that the communication message be sent via a communication network to a plurality of network addresses.

[0068] The communication network includes, for example, a wireless communication network, and for example, a WLAN communication network and / or a cellular network.

[0069] According to one specific embodiment, it is provided that if one of the results indicates the presence of an error, control signals are generated for controlling a human-machine interface of the motor vehicle so that when the human-machine interface is controlled based on the control signals, the human-machine interface reports the presence of an error, wherein the generated control signals are output.

[0070] This results in, for example, the technical advantage that the presence of an error can be efficiently reported.

[0071] The human-machine interface includes, for example, one or more signal generators, such as optical signal generators, sound signal generators, or tactile signal generators.

[0072] According to one specific embodiment, the method according to the first aspect comprises controlling a human-machine interface of the motor vehicle based on the output control signal.

[0073] According to one embodiment, it is proposed that one or more method steps are recorded, in particular one or more method steps are recorded in a blockchain.

[0074] This results in, for example, the technical advantage that the execution of the method can also be analyzed afterwards, ie after the execution of the method. In particular, recording in a blockchain results in the technical advantage that the recording can be performed in a forgery-proof and tamper-proof manner.

[0075] According to one specific embodiment, it is provided that operating state signals are received which represent an operating state of the motor vehicle, wherein the check request signal is generated as a function of the operating state of the motor vehicle.

[0076] This provides, for example, the following technical advantage: the inspection can be performed according to the operating state. In particular, this provides the following technical advantage: the inspection can be performed efficiently.

[0077] The operating state may be, for example, one of the following operating states: a starting phase, a stopping phase, a driving phase, a holding phase and a shut-down phase.

[0078] For example, it is provided that one or more checking steps are carried out during a driving phase.

[0079] This means, in particular, that one or more steps of generating a corresponding check request signal can be carried out depending on the operating state.

[0080] This means, for example, that one or more steps of generating and outputting corresponding check request signals are automatically executed during a starting phase of the motor vehicle and / or one or more steps of generating and outputting corresponding check request signals are automatically executed during a driving phase.

[0081] It should be noted that in the above statement "if one of these results indicates that an error exists," the term "result" is used as a general term or as a placeholder for the first check result, the second check result, the third check result, the corresponding self-test result and / or the collaborative test result.

[0082] According to one specific embodiment, it is proposed that the method according to the first aspect is carried out or executed by means of the device according to the second aspect.

[0083] Method features are derived in an analogous manner from corresponding device features and vice versa. This means, in particular, that the technical functions of the method according to the first aspect are derived from the corresponding technical functions of the device according to the second aspect and vice versa.

[0130] In summary, the concept described here is based on the fact that after the body has been arranged on the rolling chassis, the following actions are carried out, in particular automatically:

[0131] Check that all connections (mechanical, electrical, thermal / fluid, ...) are connected correctly.

[0132] Check whether all components (e.g. brakes, steering gear, cameras) can be addressed, i.e. whether communication with them is possible via the connections.

[0133] Check whether the vehicle body is permitted for use.

[0134] The interface, ie in particular the first and / or second interface, is for example: a mechanical interface, an electrical interface, a thermal interface, a fluid interface, a hydraulic interface. These interfaces are in particular different or in particular the same. The interface is for example a communication interface, which can also be referred to as an information interface.

[0136] In one embodiment, it is provided that a self-test of selected components and / or all components is carried out. Preferably, a self-test of those components which are involved due to the arrangement of the vehicle body on the rolling chassis is carried out.

[0137] In one embodiment, selected components or all components are tested for their interaction with each other.

[0138] In one embodiment, the functions of selected components or all components (eg, acceleration, braking, camera object recognition, etc.) are tested or checked.

[0139] In the event of one or more errors, the functions of the motor vehicle are preferably disabled, that is, this means in particular that the motor vehicle cannot be started and used.

[0140] This applies in particular to errors that endanger safety (e.g. brakes or steering that are inoperative or only partially operative).

[0141] If a minor error or an error that does not endanger safety occurs, then according to one embodiment, it is proposed that the use of the motor vehicle is permitted. In particular, it can be proposed that a corresponding prompt is output to the user. For example, the use can be permitted only with functional restrictions.

[0142] In one specific embodiment, it is provided that a user who has assembled the motor vehicle, for example, is informed of the error.

[0143] In one embodiment, it is proposed that: in the event of an error, a prompt for solving the problem in which the error occurred is notified.

This can be performed, for example, offline in a workshop by the rolling chassis manufacturer or (for example automatically) online (for example from a cloud infrastructure) and / or by the end customer himself.

[0149] In one embodiment, it is proposed that, since in this case there may also be violations that endanger security, the results are recorded. For example, it is proposed that an anti-counterfeiting method, such as blockchain, is used for the recording.

[0150] In one embodiment, it is proposed that the results are sent in addition to a test entity external to the motor vehicle that can perform the check analysis. Such an external test entity is, for example, the Technical Inspection Institute (TÜV) in Germany, or it can be the manufacturer of the rolling chassis and / or the body and / or the motor vehicle. For example, the test entity must first activate the use of the device consisting of the rolling chassis and the body arranged thereon. This means that the motor vehicle cannot be driven or cannot be used before this. This means, in particular, that according to one embodiment, the test entity must activate the motor vehicle. This occurs in particular when the check analysis has concluded that there is no error.
