Definitions
- the invention relates to a method with the features of the preamble of Claim 1.
- US-A-5 111 686 describes an apparatus provided in a vehicle Fault diagnosis. This device diagnoses and stores illegal states of a Electronic control device used to control the vehicle. The device for Fault diagnosis also compares the current operating conditions of the vehicle with the Operating conditions that existed at the time of the irregular conditions.
- DE-A-38 29 949 describes a method for operating an electrical pressure medium service brake device and a control device for performing the method known.
- the control device includes several in parallel and independently of each other Acting safety functions that prevent the brakes from operating incorrectly do. Test results affecting safety are in a non-volatile Semiconductor memory writable. Any that have occurred can also be found in the memory Error states with operating parameters and date and time can be written.
- US-A-5 491 631 is concerned with a fault diagnosis system for vehicles manufactured by different, vehicle equipment-specific fault diagnosis programs makes.
- ECU electronice control devices
- a memory is provided to make vehicles with different equipment the same electronic control devices (ECU) differentiate and use one to be able to analyze the respective equipment adapted to the fault diagnosis system a memory.
- the relevant vehicle is stored in this memory individualizing code stored on the basis of that for the vehicle in question suitable fault diagnosis program can be determined.
- the invention has for its object to a method of the type mentioned create, with the help of changing the target performance data in a simple manner is noticeable.
- the vehicle user By saving the actual performance data when this is from the target performance data deviate, the proof of a change in the target performance data without further possible.
- the vehicle user also has the opportunity to use the Proof that, for example, its target performance data has not changed and can then give his justified vis-à-vis the vehicle manufacturer or the insurance company Evidence of claims.
- the possibility of a change that cannot be completely ruled out the performance data without the influence and intervention of the vehicle user, for example when exchanging the control device and a workshop error can be for the vehicle user also lead easily. If there is a change of ownership, it will the subsequent owner possible, a possible excessive stress to recognize the internal combustion engine on the basis of the stored actual performance data. He can then refrain from buying the vehicle, for example.
- the previous user can use non-saved actual performance data proof of the proper operation of the internal combustion engine to lead. To a certain extent, the buyer of a vehicle therefore has the security purchase an internal combustion engine with a normal service life.
- the information about the temporal effectiveness delivers in particular day, Month and / or year is a good measure of the extent to which the internal combustion engine was overburdened. More ways to do this deliver consist of recording the mileage with which the vehicle with the changed actual performance data was operated.
- the storage of the actual performance data within the control unit enables the comparison of target and actual performance data using the control device perform yourself.
- the redundant storage at a point outside the Control device makes it possible to replace the control device a possible misuse or a change in the target performance data to be able to determine beyond any doubt.
- target performance data with the associated actual data can also be saved. If the manipulation is not carried out by a changed software program, but by "greasing", i.e. by changing the intake air temperature sensor resistance value, this can be done by comparing the intake air and the outside temperature in a stable condition of the vehicle, e.g. at a vehicle speed above 20km / h. Both temperature signals are available via an internal data bus. An implausibility can in addition Memory are documented.
- the possibility of documenting any manipulations can be documented and to be recognized later, can be further improved.
- the Control device with a vehicle-specific identifier, for example in the form the chassis number.
- This identifier can also be used in an additional Memory, for example the memory of another control unit become.
- the control unit is used, for example, in the context of an electronic Immobilizer used. Every time the vehicle is started, it is saved there Identifier compared with the current value of the identifier in the control device. If there is no match, the vehicle can be started, for example can be prevented or the discrepancy documented become.
- this identifier can also be an additional one times in another memory. This increases the Protection against improper simultaneous replacement of the control device and the control unit contained in the additional memory.
