Abstract

The invention relates, in particular, to a method for operating a first alarm system in a first operating mode of an at least partially electrically operated motor vehicle, which has a rechargeable battery for the electrical operation thereof, in particular a two- or four-wheel motor vehicle. In order to provide an improved method for operating an alarm system for an at least partially electrically operated motor vehicle, the following steps are proposed. In a first step, a monitoring is carried out via the motor vehicle to determine whether the motor vehicle is being electrically charged via a charging socket provided on the motor vehicle, and preferably accessible from outside for charging the rechargeable batter, even when the motor vehicle is closed. If the monitoring in the first step demonstrates that the motor vehicle is being electrically charged, in a third step, the first alarm system is operated in a second operating mode that is different from the first operating mode.

Description

Alarmanlage für ein zumindest teilweise elektrisch angetriebenes Kraftfahrzeug  Alarm system for an at least partially electrically powered motor vehicle
Die Erfindung betrifft insbesondere ein Verfahren zum Betrieb einer ersten Alarmanlage in einem ersten Betriebsmodus eines zumindest teilweise elektrisch angetriebenen Kraftfahrzeugs, das für seinen elektrischen Antrieb eine wieder aufladbare Batterie aufweist, insbesondere ein zwei- oder vierrädriges Kraftfahrzeug, gemäß dem Oberbegriff des Anspruchs 1 . The invention particularly relates to a method for operating a first alarm system in a first operating mode of an at least partially electrically driven motor vehicle having a rechargeable battery for its electric drive, in particular a two- or four-wheeled motor vehicle, according to the preamble of claim 1.
Unter einem zumindest teilweise elektrisch angetriebenen Kraftfahrzeug wird ein Kraftfahrzeug verstanden, das eine wieder aufladbare Batterie, z.B. eine Lithium-Ionen- Batterie, aufweist. Die wieder aufladbare Batterie treibt das Kraftfahrzeug im Fahrbetrieb bei seiner Fahrt über öffentliche Straßen über einen im Kraftfahrzeug vorgesehenen Elektromotor zumindest teilweise an, z.B. alternativ oder ergänzend zu einem Verbrennungsmotor oder einer Brennstoffzelle. Neben einem solchen Hybrid-Kraftfahr- zeug kann es sich bei einem erfindungsgemäßen Kraftfahrzeug auch um ein vollelektrisch angetriebenes Kraftfahrzeug handeln. By an at least partially electrically powered motor vehicle is meant a motor vehicle having a rechargeable battery, e.g. a lithium ion battery. The rechargeable battery at least partially drives the motor vehicle when driving on public roads via an electric motor provided in the motor vehicle, for example when driving. alternatively or in addition to an internal combustion engine or a fuel cell. In addition to such a hybrid motor vehicle, a motor vehicle according to the invention may also be a fully electrically driven motor vehicle.
Bekannte Verfahren zum Betrieb einer Alarmanlage für ein zumindest teilweise elektrisch angetriebenes Kraftfahrzeug sind unbefriedigend. Known methods for operating an alarm system for an at least partially electrically driven motor vehicle are unsatisfactory.
Aufgabe der Erfindung ist insbesondere die Bereitstellung eines verbesserten Verfahrens zum Betrieb einer Alarmanlage für ein zumindest teilweise elektrisch angetriebenes Kraftfahrzeug. The object of the invention is in particular the provision of an improved method for operating an alarm system for an at least partially electrically powered motor vehicle.
Diese Aufgabe wird insbesondere durch ein Verfahren nach dem unabhängigen Patentanspruch gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der abhängigen Patentansprüche. Die Erfindung geht aus von einem Verfahren zum Betrieb einer ersten Alarmanlage in einem ersten Betriebsmodus eines zumindest teilweise elektrisch angetriebenen Kraftfahrzeugs, das für seinen elektrischen Antrieb eine wieder aufladbare Batterie aufweist, insbesondere ein zwei- oder vierrädriges Kraftfahrzeug. This object is achieved in particular by a method according to the independent claim. Advantageous embodiments of the invention are the subject of the dependent claims. The invention relates to a method for operating a first alarm system in a first operating mode of an at least partially electrically driven motor vehicle, which has a rechargeable battery for its electric drive, in particular a two- or vierrädriges motor vehicle.
Erfindungsgemäß sind die folgenden Schritte vorgesehen: According to the invention, the following steps are provided:
In einem ersten Schritt wird eine Überwachung durch das Kraftfahrzeug vorgenommen, ob das Kraftfahrzeug über eine am Kraftfahrzeug vorgesehene Ladesteckdose, die vorzugsweise auch bei verschlossenem Kraftfahrzeug bzw. bei einem verschlossenen Innenraum, verschlossener Motorhaube und verschlossenem Kofferraum des Kraftfahrzeugs, von außen zur Aufladung der wieder aufladbaren Batterie zugänglich ist, elektrisch geladen wird. In a first step, a monitoring is performed by the motor vehicle, whether the motor vehicle via a charging socket provided on the motor vehicle, preferably also with a closed motor vehicle or a sealed interior, closed hood and locked trunk of the motor vehicle, from the outside to recharge the rechargeable Battery is accessible, is electrically charged.
Zeigt die Überwachung in dem ersten Schritt, dass das Kraftfahrzeug elektrisch geladen wird, wird die erste Alarmanlage in einem dritten Schritt in einem zweiten sich von dem ersten Betriebsmodus unterscheidenden Betriebsmodus betrieben. If the monitoring in the first step shows that the motor vehicle is being electrically charged, the first alarm system is operated in a third step in a second operating mode different from the first operating mode.
Bei einer Weiterbildung des erfindungsgemäßen Verfahrens ist vorgesehen, dass der zweite Betriebsmodus der ersten Alarmanlage gegenüber dem ersten Betriebsmodus der ersten Alarmanlage ergänzende und/oder alternative Überwachungsmaßnahmen für das Kraftfahrzeug aufweist. In a development of the method according to the invention, provision is made for the second operating mode of the first alarm system to have supplementary and / or alternative monitoring measures for the motor vehicle compared to the first operating mode of the first alarm system.
Bei einer Ausgestaltung des erfindungsgemäßen Verfahrens wird im Rahmen des zweiten Betriebsmodus der ersten Alarmanlage eine in dem Kraftfahrzeug vorgesehene erste Einparkhilfe aktiviert, die die Annäherung einer Person und/oder eines Gegenstands an das Kraftfahrzeug detektiert. In one embodiment of the method according to the invention, a first parking aid provided in the motor vehicle is activated as part of the second operating mode of the first alarm system, which detects the approach of a person and / or an object to the motor vehicle.
Bei einer Weiterbildung des erfindungsgemäßen Verfahrens ist vorgesehen, dass die erste Einparkhilfe mit einem ersten und einem zweiten Betriebsmodus versehen wird und der zweite Betriebsmodus der Einparkhilfe im Rahmen des zweiten Betriebsmodus der ersten Alarmanlage anstelle des ersten Betriebsmodus der ersten Einparkhilfe aktiviert wird. Entsprechend einer Ausführungsform des erfindungsgemäßen Verfahrens ist vorgesehen, dass der zweite Betriebsmodus der ersten Einparkhilfe einen ersten Schwellenwert für den Abstand einer sich nähernden Person und/oder eines sich nähernden Gegenstands aufweist, bei dessen Unterschreiten die erste Alarmanlage des Kraftfahrzeugs betätigt wird. In a development of the method according to the invention, it is provided that the first parking aid is provided with a first and a second operating mode and the second operating mode of the parking aid is activated in the second operating mode of the first alarm system instead of the first operating mode of the first parking aid. According to one embodiment of the method according to the invention, it is provided that the second operating mode of the first parking aid has a first threshold for the distance of an approaching person and / or an approaching object, below which the first alarm system of the motor vehicle is actuated.
