Abstract

A system for providing a set point increase for a vehicle combustion engine includes a control that is operable to control vehicle secondary systems to control the power consumption of the vehicle secondary systems to increase a mechanical load to the vehicle combustion engine. The load increase of the combustion engine may be for increasing the lost heat, which enhances the filtering of exhaust gases of the vehicle combustion engine. The lost heat may be utilized to increase the heat of a carbon particle filter, through which exhaust gases flow.

Claims

1. A system for providing a set point increase for a vehicle combustion engine, said system comprising:

a control operable to control vehicle secondary systems to control the power consumption of said vehicle secondary systems to increase a mechanical load to the vehicle combustion engine.

2. The system of claim 1, wherein said load increase of the vehicle combustion engine is for increasing the lost heat.

3. The system of claim 2, wherein at least one of (i) said lost heat increase enhances the filtering of exhaust gases of the vehicle combustion engine and (ii) said lost heat is principally released to the exhaust gases.

4. The system of claim 2, wherein said lost heat is utilized to increase the heat of a carbon particle filter, and wherein exhaust gases of the vehicle combustion engine flow through the said carbon particle filter.

5. The system of claim 4, wherein said carbon particle filter is heated up to its functional temperature.

6. The system of claim 5, wherein said carbon particle filter functional temperature is between about 250 degrees C. and about 800 degrees C.

7. The system of claim 1, wherein said control is operable to increase power consumption by one of said secondary systems when another of said secondary systems experiences a decrease in power consumption.

8. The system of claim 1, wherein said control uses operation modes in which said secondary systems are controlled in a manner that is substantially not perceptible to the vehicle occupants or bystanders.

9. The system of claim 8, wherein said control controls the combustion engine in a manner such that emitted torque is increased by the same amount as the torque discharged by said secondary systems.

10. The system of claim 8, wherein said control is operable to control said secondary systems in said operation mode to maximize electrical power consumption.

11. The system of claim 10, wherein said control of said secondary systems is supervised by a master control to control the combined torque consumption and to prevent said secondary systems from damaging due to overload.

12. The system of claim 11, wherein said secondary systems comprise electrical commuted current driver stages and driver controls.

13. The system of claim 12, wherein at least one of (i) said electrical commuted current driver stages are controlled in opposite directions in short time duration so that the resulting force or momentum is near zero over time, (ii) said electrical commuted current driver stages are controlled in a short cut mode and (iii) said secondary system comprises one of a starter generator and a hybrid motor generator.

14. The system of claim 8, wherein said control is operable to control said secondary systems in said operation mode to maximize mechanical discharged torque from a drivetrain of the vehicle.

15. The system of claim 14, wherein at least one of (i) said secondary system comprises a brake system of the vehicle and (ii) said secondary system comprises a fly wheel of the vehicle.

16. A system for enhancing filtering of exhaust gases of a vehicle combustion engine, said system comprising:

a control operable to control vehicle secondary systems to control the power consumption of said vehicle secondary systems to increase a mechanical load to the vehicle combustion engine;

wherein said load increase of the vehicle combustion engine is for increasing the lost heat, and wherein said lost heat increase enhances the filtering of exhaust gases of the vehicle combustion engine; and

wherein said control is operable to increase power consumption by one of said secondary systems when another of said secondary systems experiences a decrease in power consumption.

17. The system of claim 16, wherein said control is operable to control said secondary systems to at least one of (i) maximize electrical power consumption and (ii) maximize mechanical discharged torque from a drivetrain of the vehicle.

18. A system for enhancing filtering of exhaust gases of a vehicle combustion engine, said system comprising:

a control operable to control vehicle secondary systems to control the power consumption of said vehicle secondary systems to increase a mechanical load to the vehicle combustion engine;

wherein said load increase of the vehicle combustion engine is for increasing the lost heat, and wherein said lost heat increase enhances the filtering of exhaust gases of the vehicle combustion engine;

wherein said lost heat is utilized to increase the heat of a carbon particle filter, through which the exhaust gases flow; and

wherein said control is operable to increase power consumption by one of said secondary systems when another of said secondary systems experiences a decrease in power consumption.

19. The system of claim 18, wherein said control is operable to control said secondary systems to at least one of (i) maximize electrical power consumption and (ii) maximize mechanical discharged torque from a drivetrain of the vehicle.
