Definitions
- control deviation results from the actual values and setpoints assigned to the individual cylinders.
- Runtime changes in the vehicle are compensated. As a result, manufacturing costs are kept low and ride comfort is improved. These functions are usually part of the system software and are thus protected by the vehicle manufacturer in vehicle control units
- the correction values of the learning / control and correction functions can be used for workshop-based diagnostics of systems or components of the vehicle.
- the device according to the invention and the method according to the invention with the features of the independent claims have the advantage that an early warning of an unplanned failure of the vehicle can be avoided.
- Extrapolation can be used any method. Preferably, a straight line extrapolation is used.
- Exceeding the threshold control unit in the prior art checked. If the threshold value is exceeded, the driver has so far been signaled an error and suitable measures have been initiated. By checking when the extrapolated correction value exceeds the threshold value, it is possible to detect in advance when the error is likely to occur.
- Threshold this is reported. This means that the driver or the operator a certain period of time A before exceeding the
- Threshold is sent a corresponding message.
- this period of time A is chosen to be longer than a maintenance interval. It can also be provided that this period of time A is dimensioned such that a workshop can still be achieved. Especially for vehicles that drive the same route regularly, this time is such that this one
- a travel distance can be used instead of the time duration. This is especially true at
- Vehicles make sense always cope with the same or a similar route or within a certain distance by one
- the described method can be carried out completely in a control unit in a vehicle. However, it is particularly advantageous for the method to be carried out at least partially outside the vehicle in a "cloud.” This is particularly advantageous when several vehicles are monitored, for example in the case of a vehicle fleet Bus enterprise or a forwarding company the case. Furthermore, this is advantageous if several vehicles of a company are monitored, the one
- the invention relates to program code together with processing instructions for creating a computer program executable on a controller, in particular source code with compiling and / or linking instructions, the program code providing the computer program for performing all the steps of one of the described methods, if according to the processing instructions be converted into an executable computer program, so in particular compiled and / or linked.
- This program code can be given in particular by source code, which are downloadable, for example, from a server on the Internet.
- FIG. 1 is a schematic representation
- Figure 2 shows the time course of the features
- FIG. 1 shows a device for monitoring a vehicle control.
- a first vehicle is designated 100. This usually includes a control unit 110. Furthermore, further vehicles 120 may be provided, which may also include a control unit 130. This vehicle 120 or the control unit 110 transmits the data to a central processing unit 140. This performs various calculations and exchanges data with one
- This central processing unit can also be referred to as a "cloud”, which is a variety of storage devices and various computers that are decentralized or centrally located, such as providing a service provider with that storage space and computing capacity, and the other
- the display means 150 are preferably located at the vehicle owner or at the vehicle operator. For example, it can be provided that in the case of a freight forwarding company these data can be called up centrally via a computer and corresponding persons have access to this data.
- This zero quantity calibration determines the correction activation duration from which fuel is injected at the moment.
- the process according to the invention can be applied to all these processes and others
- the correction values K are plotted over the time t. Furthermore, a threshold value S is indicated. Until a time tO take the
- Correction values K an almost constant value.
- the correction values vary only from measurement to measurement within a certain range
- a time t1 is determined, which is a period of time A before the time t2.
- a warning is issued.
- This period of time A is preferably such that it corresponds to the period of time in which maintenance of the vehicle usually takes place. That is, the duration A corresponds to the maintenance interval of the vehicle.
- the method according to the invention is described below using the example of FIG.
- the correction values are determined.
- the correction values are stored in a memory.
- step 310 the program continues with step 310 and new correction values are determined. If the spread of the correction values is greater than the bandwidth, a dynamic calculation of extrapolation values is performed in step 340. In the simplest case, this is done by means of a straight line extrapolation. But there are also any other mathematical
- step 350 the intersection of the extrapolation function with the allowable limit S is calculated.
- Admissible limit values S can be applied diagnostic limits, physical
- Query 360 checks when the point of intersection is reached. Depending on the result of the query 360, an error message is output in step 370 or it is signaled in step 380 that the vehicle fails in a certain time or driving performance.
- Correction values in step 310 take place in the control unit 110 of the vehicle 100. These correction values are then transmitted via a telematics unit.
- a telematics unit For this purpose, an existing truck telematics box, a connectivity control unit with its own logic or a GSM module in the control unit can be used as a telematics unit.
- the correction values can be preprocessed in the vehicle and / or buffered.
- the correction values are transmitted to a server and preferably in one
- Controller 110 takes place and only the data is transmitted to the central unit when the threshold is exceeded. In a further embodiment, the entire process can be carried out in the control unit.
- Essential for the application of the procedure according to the invention are learning / control and correction functions. If these are not implemented and / or activated in the control unit 130, it is provided in one embodiment that these functions are monitored only at intervals, but not also on the central unit 140, i. in the "cloud", only all of which are necessary for the learning / regulation and correction functions
- Input signals are transmitted to the central unit 140.
