Procedure for the control of a pollutant control equipment

Abstract

It is suggested to use a procedure for the control of the regeneration of a pollutant control equipment arranged in the planned internal combustion engine used for powering a motor vehicle. It will be regenerated in periodical intervals by at least one stored component and a device for the execution of the process. A calculation of a route takes place due to an entry by the operator. A required regeneration of the pollutant control equipment impacts the calculation of a route. Besides protection from the pollutant control equipment the invention based procedure enables a protection against contaminant loads of the air on specific routes and beyond that an energy efficient regeneration of the pollutant control equipment.

1 . A method of controlling a regeneration in an exhaust gas system of an internal combustion engine with attached pollutant control equipment for the powering of a motor vehicle, the method comprising regenerating in periodic intervals by at least one stored exhaust component and calculating a route based upon a specification and based on a required regeneration of the pollutant control equipment.  
   
   
       2 . A method according to  claim 1 , wherein calculating includes calculating by a stored or calculated evaluation criteria for its suitability for the regeneration.  
   
   
       3 . A method according to  claim 1 , wherein calculating includes calculating a route based on a suggested route.  
   
   
       4 . A method according to  claim 1 , wherein calculating a route includes considering an anticipated drive time, distance topology, known traffic obstructions, or anticipated fuel use.  
   
   
       5 . A method according to  claim 1 , wherein calculating includes calculating a route to avoid operating conditions with a marginal exhaust gas volume flow or a high oxygen content of an exhaust gas.  
   
   
       6 . A method according to  claim 1 , wherein calculating a route includes causing a sufficient remaining drive time for an execution of a regeneration.  
   
   
       7 . A method according to  claim 1 , wherein calculating includes considering an appearance of an increased contaminant load in an exhaust gas during regeneration.  
   
   
       8 . A method according to  claim 1 , further comprising determining if a started regeneration will be retained or cancelled based on evaluation criteria.  
   
   
       9 . A device that controls a regeneration of pollutant control equipment arranged in an internal combustion engine for powering a motor vehicle, the device causing regeneration by at least one stored component by which a calculation of a route is planned due to a specification that has a planned specifically arranged internal combustion engine and a specifically arranged driving computer.
