Offenbarung der Erfindung Disclosure of the invention
Vorteile der Erfindung Advantages of the invention
Der Fahrer kann die Ausstattung seines Fahrzeugs nach dem Fahrzeugkauf selbst anpassen, beispielsweise kann der Fahrer nachträglich Ausstattungen kaufen, die er zum Zeitpunkt des Fahrzeugkaufs noch nicht brauchte oder die er sich nicht leisten konnte. The driver can customize the equipment of his vehicle after the purchase of the vehicle itself, for example, the driver can subsequently buy equipment that he did not need at the time of the purchase of the vehicle or he could not afford.
Der Fahrer muss sich beim Kauf nicht für eine bestimmte Ausstattung entscheiden. Er kann die zusätzliche Ausstattung nachträglich dazu kaufen ohne in die Werkstatt fahren zu müssen.
Wenn der Fahrer nachträglich seine Ausstattung ändert, kann der Fahrzeughersteller gleichzeitig den Fehlerspeicher auslesen und Fehlerkorrekturen mit einspielen. Dies kann beispielsweise auch ohne das Wissen des Fahrers durchgeführt werden. Vorteilhafterweise wird die Anzahl der Werkstattaufenthalte durch das Einspielen der Fehlerkorrekturen verringert. The driver does not have to decide on a particular equipment when purchasing. He can buy the additional equipment at a later date without having to drive to the workshop. If the driver subsequently changes his equipment, the vehicle manufacturer can simultaneously read the fault memory and import error corrections. This can be done, for example, without the knowledge of the driver. Advantageously, the number of workshop visits is reduced by the introduction of the error corrections.
Detaillierte Beschreibung der Ausführungsbeispiele Detailed description of the embodiments
Der Fahrer kann die Ausstattung seines Fahrzeugs nach dem Fahrzeugkauf selbst anpassen, wobei eine Anpassung insbesondere nach folgendem Verfahren abläuft. The driver can adjust the equipment of his vehicle after the purchase of the vehicle itself, with an adjustment in particular runs according to the following procedure.
In einem ersten Schritt stellt der Fahrer sein Fahrzeug ab und stellt die Zündung auf einen Zustand„ein". In a first step, the driver turns off his vehicle and sets the ignition to a state.
In einem zweiten Schritt kauft der Fahrer Softwareteile in Form einer elektronischen Datei, im beispielsweise in Form einer sogenannten„App"- Vorteilhafterweise kauft der Fahrer die App im Internet, beispielsweise über ein Mobiltelefon, und/oder der Fahrer kauft die App auf einem Speichermedium. Diese App ist auf einem Datenspeicher gespeichert, beispielsweise auf einer SD-Karte, wobei vorteilhafterweise die App vor Manipulation geschützt ist. In a second step, the driver buys software parts in the form of an electronic file, for example in the form of a so-called "app" - Advantageously, the driver buys the app on the Internet, for example via a mobile phone, and / or the driver buys the app on a storage medium. This app is stored on a data memory, for example on an SD card, wherein advantageously the app is protected against manipulation.
In einem weiteren Schritt überträgt der Fahrer die App über eine Kommunikationsschnittstelle eines Steuergeräts auf mindestens einen Datenspeicher des Steuergeräts, beispielsweise über eine Funkverbindung. Der Fahrer installiert beispielsweise eine Kommunikationssoftware auf seinem Smartphone. Mit dieser Kommunikationssoftware baut er eine Datenverbindung über die Kommunikationsschnittstelle des Steuergeräts zu dem Steuergerät des Fahrzeugs auf. Das Fahrzeug selbst hat bereits Zugriff auf das Internet, beispielsweise über eine Funkverbindung mittels der Kommunikationsschnittstelle, oder kann die entsprechenden Speichermedien und damit die App einlesen. Der Fahrer bedient sich in diesem Fall einer Funktion des Fahrzeugs um die App auf den Datenspeicher des Steuergeräts zu spielen. Es ist auch denkbar, dass das Steuergerät auf dem mindestens
einen Datenspeicher mehrere Apps speichert und der Fahrer die einzelnen Apps wahlweise aktiviert. In a further step, the driver transmits the app via a communication interface of a control device to at least one data memory of the control device, for example via a radio link. For example, the driver installs a communication software on his smartphone. With this communication software, he sets up a data connection via the communication interface of the control unit to the control unit of the vehicle. The vehicle itself already has access to the Internet, for example via a radio connection by means of the communication interface, or can read in the corresponding storage media and thus the app. The driver uses in this case a function of the vehicle to play the app on the data memory of the controller. It is also conceivable that the control unit on the at least a data store stores multiple apps and the driver selectively activates the individual apps.
In einem nächsten Schritt prüft das mindestens eine Steuergerät, beispielsweise durch eine Prüfsumme, die App auf Manipulation und/oder Fehler bei der Datenübertragung. Ergibt die Prüfung, dass die App gültig ist, also beispielsweise keine erkannte Manipulation stattgefunden hat, dann wird die neue Ausstattung aktiv, steht dem Fahrer also zur Verfügung. Ergibt die Prüfung jedoch, dass die App ungültig ist, also beispielsweise eine Manipulation durchgeführt wurde, dann setzt sich das mindestens eine Steuergeräte in den Ausgangszustand oder den Zustand mit der zuletzt verwendeten Parametrierung zurück. In a next step, the at least one control unit checks, for example by means of a checksum, the app for manipulation and / or errors in the data transmission. If the check indicates that the app is valid, that is, for example, no detected manipulation has taken place, then the new equipment is active, so the driver is available. If, however, the check reveals that the app is invalid, that is to say if, for example, a manipulation has been carried out, then the at least one control unit returns to the initial state or the state with the last used parameterization.
Eine mögliche Ausführungsform für eine App ist beispielsweise eine Änderung des Fahrzeugsounds, insbesondere bei Fahrzeugen mit Active Sound Design. One possible embodiment for an app is, for example, a change of the vehicle sound, especially in vehicles with Active Sound Design.
Weitere mögliche Ausführungsformen sind beispielsweise eine Änderung der Leistungsdaten des Fahrzeugs, eine Aktivierung eines Sportmodus bei Fahrzeugen mit Automatikschaltung, eine Änderung eines Fahrzeugverbrauchs, eine Änderung einer Schadstoffklasse, eine Aktivierung einer Sitzheizung und/oder eine Aktivierung einer Außenspiegelheizung. Further possible embodiments are, for example, a change of the performance data of the vehicle, activation of a sport mode in vehicles with automatic transmission, a change of a vehicle consumption, a change of a pollutant class, an activation of a seat heater and / or an activation of an exterior mirror heater.
Das Fahrzeug kann in einer weiteren Ausführungsform mehrere Steuergeräte mit jeweils mindestens einem Datenspeicher und mindestens einer Kommunikationsschnittstelle umfassen, wobei die Apps auf verschiedenen Datenspeichern gespeichert sind.
