An intended journey is programmed into the navigational system (23,24) which then gathers information relating to the intended journey, the controller (19) receives and stores the information and the gathered information is compared with pre-programmed route information to predict short term future vehicle operating conditions so that the controller (19) can initiate the future regeneration of the device (13) within a predicted future period of suitable vehicle operating conditions.

Description

Regeneration of a Diesel Particulate Filter Field This invention relates
to the regeneration of particulate filters that are utilised in 5 combination with internal combustion engines, particularly but not exclusively automobile diesel engines.
Background of the Invention
Particulate filters and NOx traps or absorbers are vehicle engine exhaust aftertreatment 10 devices which store continuously and regenerate periodically. In the case of the particulate filter the exhaust temperature must be sufficiently raised to burn off the collected particulate to minimize exhaust backpressure. In the case of the NOx trap, the exhaust temperature must be raised, under particular conditions to purge the stored sulphate and maximize the NOx storage which is inhibited by the presence of sulphates.
The temperature of the filter must be raised for a prolonged period of time, dependent upon the quantity of material stored in the filter. The regeneration event causes an increase in fuel consumption due to the need to increase the exhaust temperature without effecting the engine load. The necessary vehicle operating conditions favourable for 20 regeneration will often not be achieved during a car journey, especially where journey times are short or of low speed. Therefore, if the stored quantity of particulate matter of NOx is reaching a critical value, the present regeneration control strategies take the opportunity to initiate the regeneration process when a preferential change in vehicle operating systems is detected, thereby minimizing fuel consumption. However, the 25 present strategies cannot predict how long the favourable conditions will remain in force and a regeneration process may be initiated only to have the process fail due to a return to
engine idling, low speed driving conditions or engine switch off. Repeated incomplete regeneration processes could lead to high fuel consumption and possible loss of control of the exhaust aftertreatment resulting in damage to the regeneration system or emissions which do not conform with the required standards.
s Alternatively, it may be necessary to initiate the regeneration process at low speed and engine load which may result in an unnecessary increase in fuel consumption, since the fuel consumption increase is proportional to the increase in temperature required over the exhaust temperature of the particular current operating condition.
The present invention provides a strategy for the regeneration of a diesel particulate filter or a desulphatation of a NOx trap which will initiate a regeneration process in response to predicted driving conditions.
l S Statement of Invention
According to a first aspect of the present invention there is provided a method of regenerating an internal combustion engine exhaust aftertreatment device of a motor vehicle in which the vehicle is provided with a navigational system having stored information relating to vehicle routes and which is connected to a regeneration controller, 20 wherein an intended journey is programmed into the navigational system, the navigation system gathers information relating to the intended journey, the controller receives and stores information from the navigation system and the gathered information is compared with pre-programmed route information to predict short term future vehicle operating conditions so that the controller can initiate the future regeneration of the device within a 25 predicted future period of suitable vehicle operating conditions.
The method may be applied to vehicles having gasoline injection engines and is particularly useful when applied to vehicles having diesel engines, in particular for the regeneration of particulate filters and NOx traps.
s The information may be received from a GPS based navigational system and /or a traffic management system, e.g. Trafficmaster, which distributes information in relation to traffic conditions along a proposed route..
10 The controller may be programmable to recognise a repeat journey and thereby predict a suitable period of vehicle operating conditions for optimum regeneration based on previously stored information.
The controller may store information relating to the vehicle operating conditions for a 15 plurality of journeys and utilise the information to predict said suitable period.
According to a second aspect of the present invention there is provided a control system for the operation of a regeneration process for an internal combustion engine exhaust aftertreatment device, said control system including a navigational system pre 20 programmed with information relating to vehicle routes and into which an intended journey is programmable, the navigation system being capable of gathering information relating to said intended route, and a controller which receives and stores information from the navigation system, the controller being pre-programmed to process the information relating to the intended vehicle route to predict short term future vehicle
operating conditions for controlling the initiation of the regeneration of the device to occur within a predicted future period of suitable vehicle operating conditions.
The controller may be an integral part of a regeneration supervisor which is connected to S the engine ECU.
Description of the Drawings
The invention will be described by way of example and with reference to the accompanying drawings, in which: 10 Fig.l is a schematic diagram of a regeneration control system according to the present invention.
Detailed Description of the Invention
With reference to Fig.l there is shown an internal combustion engine 11, for example a I S diesel engine, having an exhaust system 12 with an exhaust aftertreatment device 13, such as a particulate filter and/or a NOx trap. The operation of the engine 11 is controlled by an electronic control unit (ECU) 14 which is connected to a plurality of engine condition sensors which may include exhaust temperature sensors IS & 16, exhaust gas pressure sensors 17 & 18 and others not shown such as engine speed sensor, engine temperature 20 sensor, torque demand sensor, air intake volumes and temperatures etc. The temperature sensorslS & 16 monitor the exhaust temperature before and after the aftertreatment device 13. The pressure sensors 17 & 18 monitor the exhaust gas pressure before and after the aftertreatment device 13, respectively.
s The ECU 14 is connected to a regeneration supervisor 19 via cables 21 and 22.. The cable 21 carries signals from the regeneration supervisor to the ECU to start and stop the regeneration process for the aftertreatment device. The cable 22 conducts signals from the ECU to the regeneration supervisor 19 which relate to the vehicle operating conditions 5 and the condition of the aftertreatment device 13 e.g. diesel particulate accumulation, NOx trap condition. All this is previously known technology and is described in detail in EP-A-1205 647 the contents of which are hereby included in the present specification.
The regeneration supervisor 19 is connected to at least one and preferably two 10 navigational systems 23,24. One navigational system 23 is a global positional satellite (GPS) based system and the other system may be traffic management system 24, e.g. Trafficmaster 'I'M. Either or both systems may be pre-programmed with information relating to vehicle routes.
15 The GPS navigational system 23 is programmable and an intended specific route relating to a respective journey can be programmed into its memory. The regeneration supervisor 19 may then access the information relating to vehicle routes to search for known sections of high speed road, e.g. motorway, dual carriageway within the intended route. The regeneration system will then know that regeneration can be initiated during the high 20 speed portion of the route. Since the GPS system is constantly monitoring the location of the vehicle, the supervisor can initiate the regeneration process as soon as that road section is reached provided that other conditions are fulfilled. This will help reduce fuel consumption during the regeneration process.
The traffic management system 24 will gather information about known stoppages or traffic congestion along the intended route the supervisor 19 may compare this information with the GPS information to check if regeneration is possible along the high speed road sections.
s The regeneration supervisor may be programmed to recognise previously used routes when a previously used intended route is programmed into the GPS or Trafficmaster systems 23,24.
10 The supervisor may be configured to act interactively with the navigation system and suggest alternative routes in order to facilitate regeneration.
The supervisor may also learn about the manner in which the vehicle is driven.
