The invention relates to a method for initializing a motor vehicle. The invention furthermore relates to a device, a rolling chassis, a vehicle body, a computer program and a machine-readable memory medium.
A rolling chassis generally refers to a chassis or a running gear comprising a drive motor and a drivetrain, such that a rolling chassis can travel under its own drive power.
A vehicle body is commonly arranged on such a rolling chassis.
An advantage in the use of a rolling chassis lies in particular in the fact that several possible vehicle bodies can be provided for one rolling chassis, such that different motor vehicles can be produced efficiently.
The rolling chassis here may have or provide other functionalities and/or components than the vehicle body.
As a result, for example, functionalities which are not available by means of the vehicle body cannot be operated by the rolling chassis. For example, functionalities cannot be operated and executed in the rolling chassis because, for example, data are not available from the vehicle body.
This circumstance needs to be taken into consideration in the initialization of a motor vehicle.
The object on which the invention is based can be seen in providing a concept for efficiently initializing a motor vehicle, wherein the motor vehicle comprises an arrangement having a rolling chassis and a vehicle body arranged on the rolling chassis.
Said object is achieved by means of the respective subject matter of the independent claims. Respectively dependent subclaims relate to advantageous refinements of the invention.
According to a first aspect, a method is provided for initializing a motor vehicle, wherein the motor vehicle comprises an arrangement having a rolling chassis and a vehicle body arranged on the rolling chassis comprising the following steps:
receiving first specification signals which represent a first specification of the rolling chassis, wherein the first specification indicates which components and/or which functionalities can be provided solely by means of the rolling chassis, wherein the first specification furthermore indicates parameters for parameterizing the indicated components and/or functionalities of the rolling chassis,
receiving second specification signals which represent a second specification of the vehicle body, wherein the second specification indicates which components and/or which functionalities can be provided solely by means of the vehicle body, wherein the second specification furthermore indicates parameters for parameterizing the indicated components and/or functionalities of the vehicle body,
determining on the basis of the first and second specification which of the components and/or which of the functionalities of the rolling chassis and of the vehicle body can be provided by means of the arrangement consisting of rolling chassis and vehicle body,
generating initialization signals, which represent initialization data for initializing the motor vehicle, on the basis of the first and second specification, and
outputting the generated initialization signals in order to initialize the motor vehicle.
According to a second aspect, a device is provided which is configured to execute all of the steps of the method according to the first aspect.
According to a third aspect, a rolling chassis is provided which comprises the device according to the second aspect.
According to a fourth aspect, a vehicle body is provided which comprises the device according to the second aspect.
According to a fifth aspect, a motor vehicle is provided comprising an arrangement consisting of a rolling chassis and a vehicle body arranged on the rolling chassis, and the device according to the second aspect.
According to a sixth aspect, a computer program is provided which comprises commands which, when the computer program is executed by a computer, for example by the device according to the second aspect, cause said computer or said device to execute a method according to the first aspect.
According to a seventh aspect, a machine-readable memory medium is provided on which the computer program according to the sixth aspect is stored.
The invention is based on and includes the knowledge that the above object can be achieved in that, after the vehicle body is arranged on the rolling chassis, the following actions are carried out automatically:
checking which components and/or functionalities are available in the rolling chassis and which components and/or functionalities are available in the vehicle body;
defining which components and/or functionalities are available from the combination of rolling chassis and vehicle body; and
initializing, in particular parameterizing, the components and/or functionalities in the rolling chassis and in the vehicle body in accordance with the combination of rolling chassis and vehicle body.
In other words, this means that the above object can be achieved in that it is determined on the basis of the first and second specification which of the components and/or which of the functionalities of the rolling chassis and of the vehicle body can be provided by means of the arrangement consisting of rolling chassis and vehicle body, wherein, in accordance with a result of this determination, initialization signals are generated, which represent initialization data for initializing the motor vehicle, on the basis of the first and second specification.
The initialization data therefore refer in particular to data which are suitable for initializing the motor vehicle.
An initializing of the motor vehicle comprises in particular defining permissible driving properties, in particular acceleration, speeds, cornering speeds and maximum speeds.
An initializing of the motor vehicle comprises in particular defining whether a trailer may be attached to the motor vehicle.
An initializing of the motor vehicle comprises in particular defining braking properties.
The definition should be considered with respect to the arrangement of rolling chassis and vehicle body, i.e. for the motor vehicle. This is because it is then possible to differentiate the permissible driving properties and/or whether a trailer may be attached to the motor vehicle and/or the braking properties of a motor vehicle, for example of a sports motor vehicle comprising a sports vehicle body, from a motor vehicle, for example a sprinter motor vehicle comprising a sprinter vehicle body.
Thus, in particular, the technical advantage is therefore brought about that the motor vehicle can be initialized efficiently. That is therefore to say in particular that a concept for efficiently initializing a motor vehicle is thereby provided in an advantageous manner.
Furthermore, different vehicle bodies can be used in an efficient way for a rolling chassis.
According to one embodiment, it is provided that the method is carried out or executed automatically after the vehicle body is arranged on the motor vehicle.
According to one embodiment, it is provided that the method is initiated manually after the vehicle body is arranged on the rolling chassis.
According to one embodiment, the method according to the first aspect is a computer-implemented method.
According to one embodiment, it is provided that chassis specification demand signals are generated and output which represent a demand for the first specification, and therefore the first specification signals are received in response to the outputting of the chassis specification demand signals.
Thus, for example, the technical advantage is achieved that the first specification can be attained or received efficiently.
According to one embodiment, it is provided that chassis identification signals are received which represent a chassis identification of the rolling chassis, wherein the chassis specification demand signals are generated on the basis of the chassis identification, and therefore the demand for the first specification comprises the chassis identification.
Thus, for example, the technical advantage is achieved that the first specification can be requested efficiently. For example, the chassis identification can be used in order to read the first specification from a database comprising a plurality of specifications for a plurality of chassis.
According to one embodiment, it is provided that vehicle body specification demand signals are generated and output which represent a demand for the second specification, and therefore the second specification signals are received in response to the outputting of the vehicle body specification demand signals.
Thus, for example, the technical advantage is achieved that the second specification can be obtained or received efficiently.
According to one embodiment, it is provided that vehicle body identification signals are received which represent a vehicle body identification of the vehicle body, wherein the vehicle body specification demand signals are generated on the basis of the vehicle body identification, and therefore the demand for the second specification comprises the vehicle body identification.
Thus, for example, the technical advantage is achieved that the second specification can be requested efficiently. For example, the vehicle body identification can be used in order to read the second specification from a database comprising a plurality of specifications for a plurality of vehicle bodies.
According to one embodiment, it is provided that the outputting of the demand signals for the corresponding specification comprises sending the demand signals to a local memory and/or sending the demand signals via a communication network to a remote specification server.
Thus, for example, the technical advantage is achieved that the corresponding specification can be obtained or received efficiently.
The demand signals in this embodiment are a generic term for the vehicle body specification demand signals and/or for the chassis specification demand signals.
A communication network within the meaning of the description comprises, for example, a WLAN communication network and/or a mobile network.
A local memory is, for example, integrated in the device or included by the latter.
A local memory is, for example, included by the vehicle body, by the rolling chassis and/or by the motor vehicle.
According to one embodiment, it is provided that the initialization data comprise parameters for a respective parameterizing of the determined components and/or functionalities and/or function state data which indicate which components and/or functionalities may be enabled for use.
Thus, for example, the technical advantage is achieved that the determined components and/or functionalities can be efficiently parameterized. Furthermore, for example, the technical advantage is thereby achieved that it can be efficiently indicated which components and/or functionalities may be enabled for use.
A parameterizing comprises, for example, defining in which position, in particular at which height, a sensor, in particular a surroundings sensor, in particular a video camera comprising a video sensor, is arranged on the vehicle body. This differs, for example, for a sprinter and a convertible. Thus, for example, the fact that sensors can be arranged at different positions in different vehicle bodies can be efficiently taken into consideration.
A parameterizing comprises, for example, defining motor settings of a drive motor of the rolling chassis. That is to say, it is defined in particular which motor settings are expedient and/or necessary and/or prescribed on the basis of the superstructure.
A parameterizing comprises, for example, defining a braking behavior. That is to say, it is determined in particular how the motor vehicle behaves, with it being defined on the basis of the behavior how braking has to take place. For example, a sprinter has a different center of gravity from a passenger vehicle. Braking therefore has to be carried out differently. For example, an electronic stability program (ESP) has to behave differently. That is therefore to say in particular that defining a braking behavior comprises defining ESP parameters.
According to one embodiment, it is provided that one or more method steps and/or at least some, in particular all, initialization data are documented, in particular are documented in a blockchain.
Thus, for example, the technical advantage is achieved that, even after the method has been carried out, it can be understood efficiently on the basis of the documentation how the method has proceeded in detail. The use of a blockchain for the documenting has in particular the technical advantage that the steps can be documented in a manipulation-proof manner.
According to one embodiment, it is provided that prior to the outputting of the generated initialization signals in order to initialize the motor vehicle, the initialization data are sent for checking to a remote checking facility via a communication network, wherein, in response to the sending of the initialization data to the remote checking facility, result signals are received which represent a result of the checking by the remote checking facility, wherein, depending on the result, the generated initialization signals are output or the initialization data are revised on the basis of the result, such that revised initialization signals are generated and output which represent the revised initialization data.
Thus, for example, the technical advantage is achieved that efficient checking of the initialization data can be carried out.
A remote checking facility comprises, for example, a manufacturer of the rolling chassis and/or a manufacturer of the vehicle body and/or the TUV (Technischer Überwachungsverein [Technical Inspection Association]).
For example, it is provided that operation of the motor vehicle is disabled before the result is received.
For example, it can therefore be ensured in an efficient and advantageous manner that, prior to the operation of the motor vehicle, the initialization data can be checked.
The result of the remote checking facility can indicate, for example, that the initialization data are free from error.
In this case, it is then provided, for example, that the generated initialization signals are output.
The result of the remote checking facility can indicate, for example, that the initialization data have errors. In this case, it can be provided, for example, that the revision of the initialization signals comprises correcting the errors.
The result of the remote checking facility can indicate, for example, that one or more components and/or one or more functionalities may be made available only to a limited extent, if at all. In this case, the revising of the initialization data comprises, for example, revising the corresponding parameters and/or the functional state data on the basis of this result.
According to one embodiment, it is provided that the method according to the first aspect is executed by means of the device according to the second aspect.
Technical functionalities of the device according to the second aspect emerge in an analogous manner from corresponding technical functionalities of the method according to the first aspect, and vice versa.

A chassis within the meaning of the description is a motor vehicle chassis. That is therefore to say that a rolling chassis is a motor vehicle chassis.
A vehicle body within the meaning of the description is a motor vehicle body.
For the German expression “Karosserie” [“vehicle body”], the terms “body” or “top hat” may be used in English. It follows from this that the expression “Karosserie” [“vehicle body”] in German may also be substituted by the expression “Aufbau” [“superstructure”].
According to one embodiment, the expression “vehicle body” or “motor vehicle body” may be interpreted broadly. For example, according to one embodiment, the vehicle body may comprise one or more of the following components: motor vehicle seat, dashboard, gear shift lever, motor vehicle window, motor vehicle door, motor vehicle interior trim, air bag, assistance system, video camera, human-machine interface, tachometer.
The expression “vehicle body” can thus refer in the context of this description to the upper part (“top hat”) of a motor vehicle, which is arranged on a chassis. The vehicle body may thus, analogously to a prefabricated part of a prefabricated house, be a component that has already been manufactured to such a degree that a finished motor vehicle, that is to say in particular a motor vehicle which is ready to drive, is formed after the vehicle body has been arranged on the rolling chassis.
According to one embodiment, a rolling chassis comprises one or more of the following components: wheel, axle, drive motor, steering system, brake, frame, thermal components, battery, battery housing, sensor, in particular surroundings sensor (for example: radar sensor, lidar sensor, ultrasound sensor, magnetic field sensor, infrared sensor, video sensor), control unit (referred to as “ECU”, “electronic control unit”), PC (personal computer).
According to one embodiment, the rolling chassis may thus, analogously to a prefabricated part of a prefabricated house, be a component that has already been manufactured to such a degree that a finished motor vehicle, that is to say in particular a motor vehicle that is ready to drive, is formed after the vehicle body has been arranged on the rolling chassis.
The rolling chassis thus refers in particular to the lower component in relation to the upper component (vehicle body). Thus, according to one embodiment, a finished motor vehicle, that is to say in particular a motor vehicle that is ready to drive, is formed as a result of the arrangement of the upper component (vehicle body) and lower component (rolling chassis), wherein the upper component is arranged on the lower component.

According to one embodiment, it is provided that the functional states (enable operations) and parameterizations are additionally sent for checking analysis to a checker responsible for this purpose (remote checking facility) (for example OEM; TUV) and only after release by the latter is the rolling chassis with the vehicle body enabled. That is therefore to say in particular that, for example, no journey and/or use of the arrangement consisting of rolling chassis and vehicle body is possible previously.
