DE102004060796A1 - Motor vehicle e.g. car, has controller so that tank cover lid is opened by disconnecting internal combustion engine for automatically closing windows, where lid is opened until deactivation of electrical load is stopped - Google Patents

Abstract

The vehicle has a controller for controlling a locking and unlocking device for doors, windows and a tank cover lid. The controller is designed such that the tank cover lid is opened by disconnecting an internal combustion engine for automatically closing the windows. Electrical load of the vehicle is deactivated and the tank cover lid is opened until the deactivation of the electrical load is stopped. The tank cover locks a tank neck, and the tank cover lid covers the tank that is connected with the internal combustion engine for supplying fuel to the engine.

Description

The The invention relates to a motor vehicle with fuel cap flap, in particular with remotely-lockable fuel cap flap, according to the preamble of the claim 1.

Around a danger to prevent the refueling of motor vehicles it is known that at gas stations signs are attached to it draw attention to that during of the refueling process the engine is to be turned off.

Furthermore, from the DE 196 20 873 A1 a central locking device with a plurality of locking and unlocking devices (VEE's) for flaps and doors of the motor vehicle, which has a VEE's independently switchable VEE for the fuel filler flap. This ensures that the VEE of the fuel filler flap automatically locks the fuel filler flap during operation of the vehicle and refueling of the motor vehicle is possible only as a function of the operating state of the internal combustion engine.

The DE 102 40 328 A1 describes a heater or heater for a motor vehicle, which automatically shuts off when unlocking or opening the fuel filler flap.

Of the Invention is the object of a motor vehicle with a To create gas cap door, which ensures increased safety when refueling is.

According to the invention Problem solved by the entirety of the features of claim 1. Thereby, that on the one hand, the fuel cap flap (the tank lid itself body covering) only open when the engine is switched off lets and to the other that through the opening or the initiation of the opening process the fuel filler cap or the gas cap itself all automatically closable window be closed automatically and / or in the open position of a lockable Window a warning signal is generated and then electrical Disabled consumer (preferably all electrical consumers) of the motor vehicle and remain disabled until at least the fuel cap is locked again, the safety when refueling the motor vehicle clearly increased. This ensures that while the refueling process neither from a running engine nor from electric operated or activated consumers can pose a risk. Prefers are the electrical consumers only by opening the gas cap itself deactivated. In a particularly preferred embodiment of Invention are the means for deactivating the electrical consumers designed such that the unlocking of the fuel cap flap automatically takes place and the release due to a Entriegelungsbefehls only occurs when all vehicle doors (including tailgate or trunk lid) and all vehicle windows (including sunroof) are closed. Preferably, all the flaps of the ventilation system in a closed position (Circulating air) transferred.

In a further preferred embodiment of Invention are also electrical consumers that are not compulsory are directly connected to the electrical system or from but also via a device-own energy supply feature, by opening the filler cap or by opening of the fuel cap deactivated. In particular, mobile phones over a Radio link are coupled to the motor vehicle (for example, to the Handsfree) are in accordance with the preferred execution by the initiation of the opening process or the opening process the fuel filler cap or fuel cap is deactivated. For this is the Control device for controlling locking and unlocking devices and the electrical consumers operatively connected to the motor vehicle designed such that a shutdown of the device's own Energy supply takes place. Car phones that are stuck with the anyway Motor vehicle are connected like other electrical consumers only from the electrical energy supply of the electrical system separated.

In first line are by opening the fuel filler cap or the gas cap, in particular the auxiliary heater and / or the auxiliary ventilation and / or the fuel pump and / or the starter and / or the electric Sunroof and / or the power windows and / or the cigarette lighter and / or the horn and / or the driving light device and / or the Interior light device can be deactivated or from the electrical system formed separable.

Of the The invention is not on motor vehicles with conventional Gasoline or diesel fuel internal combustion engines limited, but also includes motor vehicles with fuel cell operation.

Claims (5)

Motor vehicle comprising an internal combustion engine, one with the internal combustion engine for the purpose of supplying the internal combustion engine with fuel associated tank with a tank lid for sealing the filler neck and a filler cap to cover the closable with the tank filler neck filler neck and a control device for controlling the internal combustion engine and a further control device for controlling locking and unlocking devices for doors, windows and flaps and the like, the further Control device is designed such that the filler cap can be opened only when the engine is switched off, characterized in that means are provided which ensure that automatically closed by the initiation of the opening process or by opening the filler cap or the gas cap all automatically closed windows and / or in the open position of a closable window, a warning signal is generated and then electrical consumers of the motor vehicle are forcibly disabled and that as long as the filler cap or the fuel cap is open, activation of the previously deactivated electrical consumers is prevented. Motor vehicle according to claim 1, characterized in that in that the means for deactivating the electrical consumers are such are formed so that the unlocking of the fuel cap flap automatically takes place and the release due to a Entriegelungsbefehls only occurs when all vehicle doors and all vehicle windows are closed. Motor vehicle according to one of the preceding claims, characterized characterized in that electrical consumers with own device Energy supply, which are operatively connected to the motor vehicle - in particular via a Radio connection with the car operatively connected mobile phones - through opening the Tank lid are deactivated. Motor vehicle according to the preceding claim, characterized in that the control device is used to control interlocking and unlocking devices and those operatively connected to the motor vehicle electrical loads are designed such that a shutdown the device's own energy supply he follows. Motor vehicle according to one of the preceding claims, characterized characterized in that by opening the fuel filler cap or the gas cap the auxiliary heater and / or the auxiliary ventilation and / or the fuel pump and / or the starter and / or the electric Sunroof and / or the cigarette lighter and / or the firmly integrated Car phone and / or the windows and / or the horn deactivated is / are.
