Abstract
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.
Claims7
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.
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.
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.
