receiving (201) measured values of a set of parameters from one or more sensors provided in the SCR module (100);

comparing (202) the received values with a set of pre-determined data points stored in the ECU (104);

indicating (203) value of degree of filter (102) clogging in DEF filter (102) to the vehicle user.
2. The method of detecting a degree of clogging in a diesel exhaust fluid (DEF) filter (102) as claimed in claim 1, where the set of parameters include at least a value of current intake for the DEF pump (103) to reach mechanical stop point.
3. The method of detecting a degree of clogging in a diesel exhaust fluid (DEF) filter (102) as claimed in claim 1, where the set of parameters include at least a time duration taken by the DEF pump (103) to reach mechanical stop point.
4. The method of detecting a degree of clogging in a diesel exhaust fluid (DEF) filter (102) as claimed in claim 1, where the pre-determined data points comprise calculated values of the set of parameters.
5. The method of detecting a degree of clogging in a diesel exhaust fluid (DEF) filter (102) as claimed in claim 1, where indicating the value of degree of filter (102) clogging can be through audio or visual means.
6. An Electronic control unit (ECU (104)) of a vehicle adapted to detect a degree of clogging in a diesel exhaust fluid (DEF) filter (102) of an Selective Catalytic Reduction (SCR) module, the ECU (104) configured to:
receive (201) measured values of a set of parameters from one or more sensors provided in the SCR module (100) from one or more sensors provided in the SCR module (100), the set of
parameters include a value of current intake for the DEF pump (103) to reach the mechanical stop point and at least a time duration taken by the DEF pump (103) to reach the mechanical stop point;

compare (202) the received values with a set of pre-determined data points stored in the ECU (104), the pre-determined data points comprise calculated values of the set of parameters;

indicate (203) value of degree of filter (102) clogging in DEF filter (102) to the vehicle user.
7. The ECU (104) of a vehicle adapted to detect a degree of clogging in a diesel exhaust fluid (DEF) filter (102) of an Selective Catalytic Reduction (SCR) module as claimed in claim 6, where indicating the value of degree of filter (102) clogging can be through audio or visual means.

, Description:The present disclosure proposes a method for detecting a degree of filter (102) clogging in a diesel exhaust fluid (DEF) filter (102) of a Selective Catalytic Reduction (SCR) module. An Electronic control unit (ECU (104)) of a vehicle is adapted to detect a degree of clogging in a diesel exhaust fluid (DEF) filter (102). In step 201 the ECU (104) receives measured values of a set of parameters from one or more sensors provided in the SCR module (100). In step 202, the ECU (104) compares the received values with a set of pre-determined data points stored in the ECU (104). In step 203, the ECU (104) indicates the value of degree of filter (102) clogging in DEF filter (102) to the vehicle user.
