Abstract

Abstract The invention is directed to a system for electronically open-loop controlling or closed-loop controlling the power of an internal combustion engine of a motor vehicle with an electrically actuable actuator influencing the engine power. The adjustment of this actuator is undertaken in dependence on a predetermined and an actual value for producing a match between pregiven and actual values. With the disappearance of a previously detected electrical disturbance of the system, the function is again taken up in a delayed manner.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 113 words
A system for electronically controlling the power of an internal combustion engine of a motor vehicle, the system comprising: an electrically actuable actuator for influencing the power of the engine; adjusting means for adjusting said actuator in dependence upon a pregiven value and an actual value for producing a match between said values; checking means for checking a change of the pregiven value and the actual value of the position of the actuator; derivation means for deriving the presence and discontinuance of an electrical fault from said change; and, means for resuming the function of said system in a delayed manner after the discontinuance of a previously detected electrical fault of the system.
Claim 2
Independent Claim 113 words
A system for electronically controlling the power of an internal combustion engine of a motor vehicle, the system comprising: an electrically actuable actuator for influencing the power of the engine; adjusting means for adjusting said actuator in dependence upon a pregiven value and an actual value for producing a match between said values; checking means for checking a change of the pregiven value and the actual value of the position of the actuator; derivation means for deriving the presence and discontinuance of an electrical fault from said change; and, means for resuming the function of said system in a delayed manner after the discontinuance of a previously detected electrical fault of the system.
Claim 3
Dependent Claim 43 words
The system of claim 1, wherein an electrical interruption in the drive circuit is detected from an actuator moving in the direction of its closed position and from a desired value which undergoes a change in a manner which is not the same.
Claim 4
Dependent Claim 42 words
The system of claim 1, wherein the control is established in such a manner, after discontinuance of a previously detected fault condition, that the actuator position is controlled to a position pregiven by the control system pursuant to a pregiven time function.
Claim 5
Dependent Claim 51 words
The system of claim 1, wherein with the discontinuance of a previously detected electrical fault, when the position of the actuator begins to follow the pregiven value, the drive signal for the actuator is pregiven such that the position of the actuator approaches the pregiven desired value in a time-delayed manner.
Claim 6
Independent Claim 111 words
A system for electronically controlling the power of an internal combustion engine of a motor vehicle, the system comprising: an electrically actuable actuator for influencing the power of the engine; adjusting means for adjusting said actuator in dependence upon a pregiven value and an actual value for producing a match between said values; checking means for checking a change of the pregiven value and the actual value of the position of the actuator; derivation means for deriving the presence of an electrical fault from said change; and, means for resuming the function of said system in a delayed manner after the discontinuance of a previously detected electrical fault of the system.
Claim 7
Independent Claim 111 words
A system for electronically controlling the power of an internal combustion engine of a motor vehicle, the system comprising: an electrically actuable actuator for influencing the power of the engine; adjusting means for adjusting said actuator in dependence upon a pregiven value and an actual value for producing a match between said values; checking means for checking a change of the pregiven value and the actual value of the position of the actuator; derivation means for deriving the presence of an electrical fault from said change; and, means for resuming the function of said system in a delayed manner after the discontinuance of a previously detected electrical fault of the system.
Claim 8
Dependent Claim 43 words
The system of claim 5, wherein an electrical interruption in the drive circuit is detected from an actuator moving in the direction of its closed position and from a desired value which undergoes a change in a manner which is not the same.
Claim 9
Dependent Claim 42 words
The system of claim 5, wherein the control is established in such a manner, after discontinuance of a previously detected fault condition, that the actuator position is controlled to a position pregiven by the control system pursuant to a pregiven time function.
Claim 10
Dependent Claim 51 words
The system of claim 5, wherein with the discontinuance of a previously detected electrical fault, when the position of the actuator begins to follow the pregiven value, the drive signal for the actuator is pregiven such that the position of the actuator approaches the pregiven desired value in a time-delayed manner.
Claim 11
Independent Claim 111 words
A system for electronically controlling the power of an internal combustion engine of a motor vehicle, the system comprising: an electrically actuable actuator for influencing the power of the engine; adjusting means for adjusting said actuator in dependence upon a pregiven value and an actual value for producing a match between said values; checking means for checking a change of the pregiven value and the actual value of the position of the actuator; derivation means for deriving the presence of an electrical fault from said change; and, means for resuming the function of said system in a delayed manner after the discontinuance of a previously detected electrical fault of the system.
Claim 12
Independent Claim 111 words
A system for electronically controlling the power of an internal combustion engine of a motor vehicle, the system comprising: an electrically actuable actuator for influencing the power of the engine; adjusting means for adjusting said actuator in dependence upon a pregiven value and an actual value for producing a match between said values; checking means for checking a change of the pregiven value and the actual value of the position of the actuator; derivation means for deriving the presence of an electrical fault from said change; and, means for resuming the function of said system in a delayed manner after the discontinuance of a previously detected electrical fault of the system.
Claim 13
Dependent Claim 43 words
The system of claim 9, wherein an electrical interruption in the drive circuit is detected from an actuator moving in the direction of its closed position and from a desired value which undergoes a change in a manner which is not the same.
Claim 14
Dependent Claim 42 words
The system of claim 9, wherein the control is established in such a manner, after discontinuance of a previously detected fault condition, that the actuator position is controlled to a position pregiven by the control system pursuant to a pregiven time function.
Claim 15
Dependent Claim 50 words
The system of claim 9, wherein the discontinuance of a previously detected electrical fault, when the position of the actuator begins to follow the pregiven value, the drive signal for the actuator is pregiven such that the position of the actuator approaches the pregiven desired value in a time-delayed manner.
