Abstract
Official abstract text for this publication.
In a method for operating a motor vehicle having an internal combustion engine, pre-heating measures (7) for reaching operating temperatures for components of the exhaust-gas post-treatment system and/or for a lambda probe of the motor vehicle are provided prior to the departure (10) of the motor vehicle. The activation of a transducer (1) by a driver of the motor vehicle for explicitly announcing an impending departure of the motor vehicle is provided as the trigger for the pre-heating measures (7), in particular for avoiding an unnecessary initiation of pre-heating measures.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for operating a motor vehicle having an internal combustion engine, wherein pre-heating measures ( 7 ) for reaching operating temperatures for components of the exhaust-gas post-treatment system, for a lambda probe of the motor vehicle, or both are performed prior to the departure ( 10 ) of the motor vehicle, wherein the activation of a transducer ( 1 ) by a driver of the motor vehicle for explicitly announcing an impending departure of the motor vehicle is provided as a trigger of the pre-heating measures ( 7 ), wherein the departure of the motor vehicle is delayed ( 11 ) as long as the operating temperature envisaged for components of the exhaust-gas post-treatment system, for the lambda probe, or for both have not yet been reached by the pre-heating measures. 2. A method for operating a motor vehicle having an internal combustion engine, wherein pre-heating measures ( 7 ) for reaching operating temperatures for components of the exhaust-gas post-treatment system, for a lambda probe of the motor vehicle, or both are performed prior to the departure ( 10 ) of the motor vehicle, wherein the activation of a transducer ( 1 ) by a driver of the motor vehicle for explicitly announcing an impending departure of the motor vehicle is provided as a trigger of the pre-heating measures ( 7 ), wherein the pre-heating measures are terminated in the event that no departure takes place within a predefinable temporal period despite the explicit announcement of an impending departure. 3. An electronic control apparatus configured to control operation of a motor vehicle having an internal combustion engine, wherein pre-heating measures ( 7 ) for reaching operating temperatures for components of the exhaust-gas post-treatment system, for a lambda probe of the motor vehicle, or both are performed prior to the departure ( 10 ) of the motor vehicle, wherein the activation of a transducer ( 1 ) by a driver of the motor vehicle for explicitly announcing an impending departure of the motor vehicle is provided as a trigger of the pre-heating measures ( 7 ), and wherein the departure of the motor vehicle is delayed ( 11 ) as long as the operating temperature envisaged for components of the exhaust-gas post-treatment system, for the lambda probe, or for both have not yet been reached by the pre-heating measures. 4. The electronic control apparatus according to claim 3 , wherein the pre-heating measures are terminated in the event that no departure takes place within a predefinable temporal period despite the explicit announcement of an impending departure. 5. The electronic control apparatus according to claim 3 , wherein, in the event of a requested departure of the motor vehicle without any prior activation of the transducer by the driver, the departure of the motor vehicle, the engine start, or both are delayed and pre-heating measures ( 7 ) are performed. 6. The method according to claim 1 , wherein the pre-heating measures are terminated in the event that no departure takes place within a predefinable temporal period despite the explicit announcement of an impending departure. 7. The method according to claim 1 , wherein, in the event of a requested departure of the motor vehicle without any prior activation of the transducer by the driver, the departure of the motor vehicle, the engine start, or both are delayed and pre-heating measures ( 7 ) are performed.
