Definitions
- the invention relates to a method of calculating a cumulative driving time interruption by means of a Kontrollgerä ⁇ tes recording activities of the driver, the cumulative driving time interruption of a particular driver is calculated as the respective accumulated time from steering time interruptions of at least 15 minutes duration since the end the last accumulated driving time interruption of at least 45 minutes calculated in this way.
- the new generation of tachographs records the activities of a vehicle driver, namely steering, readiness, interruption or rest or work, no longer, like a conventional tachograph, by means of a paper chart disc, but stores activities and the associated functions Time intervals digitally on a data carrier.
- each driver is assigned a data card which has an internal memory in which driver-related data and the recorded data are stored.
- a digital tachograph referred to in this document as a control device must be able to calculate a cumulative driving time interruption also defined there, so that certain minimum values and maximum values for rest periods and driving times are complied with can.
- the invention has set itself the task of providing a method for calculating the cumulative driving time interruption by means of a control device, which is accompanied by a reduced computing time and simultaneously meets the high safety requirements.
- a first step of the calculation method previous records be checked from the present time point in negative time sequence for the presence of an uninterrupted last period of at least 45 minutes duration of the steering time interruption
- the accumulated driving time interruption is set to 0, in a third step from the time reference mark, starting in positive time sequence, the accumulated time from driving time interruption of at least 15 Minutes, until a time total of at least 45 minutes duration is reached, in a 4th step, the time limit ending in the third step, which is the final time period of the summation, is set as a new reference mark and steps 2 ., 3., 4. be repeated in succession until the present time is reached.
- the method according to the invention sets a reference mark at a certain point in the past, which marks the start of the time period to be evaluated. In this way, the invention circumvents the actual requirement to evaluate the entire recording period of previous activities in the calculation of the cumulative driving time interruption. Only then an acceptable access time and a feasible power fail concept are made possible.
- the advantages of the method according to the invention are greater, the longer the Period of previous activity records.
- the constant shift of the reference mark minimizes the time interval to be evaluated with respect to the length, whereby the shortest calculation times can be realized. At the same time, all requirements of the EC Regulation are met without compromise.
- An advantageous development of the invention provides that in a first step of the method, the time of the beginning of the calculation is set as the present time.
- this present time point can be assumed to be a constant value for the duration of the calculation.
- a further possibility is to add a mean time constant representative of the calculation duration during the program run before reaching the end of the program to the counter instant, so that the entire evaluation also includes the running time of the calculation method.
- the most precise variant is to define the present time even during the course of the calculation process as the time progresses, so that the most accurate result can always be obtained with the evaluation.
- the reference mark is first set to the beginning of the recording of the activities.
- This embodiment of the invention expediently takes into account the rarer case that during the operating time of the control device, possibly in association with an identity of a vehicle driver, there has not yet been a steering time interruption of 45 minutes duration. In In realistic operating situations, this case should also be handled with acceptable computing times.
- control device has a first memory in which reference marks are respectively assigned to an identity and the control unit is stored before the first step or between the first and second steps
- the method of the calculation first checks the presence of a reference mark assigned to the identity for which the calculation is to be carried out and, if an associated reference mark of the calculation is present, bases the stored assigned reference mark on the calculation.
- the vehicle driver does not initiate a calculation by means of a data card which is assigned to him, but rather by means of another external data memory which in some way enters into a connection suitable for data transmission with the control unit.
- control unit For precise recording of the operational data of the vehicle, it makes sense if the control unit is connected to a transmitter which communicates a variable correlated with the speed of the vehicle to the control unit for recording.
- the control device has an external interface, in particular a data card interface. recording with contact elements for data transmission, to which an external data carrier with a second memory, in particular a special data card, can be connected.
- the data card serves not only to identify the vehicle driver but also to transmit the records of previous activities that are associated with the identity of the vehicle driver.
- the external data carrier in the second memory contains information on the identity of the vehicle driver.
- control device has controls by means of which the driver can enter information to be recorded activities in the control device.
- control device it is expedient to define standard assignments which the control device determines for the activities to be recorded, although the input is expected but not made.
- FIG. 1 shows a simplified, schematic representation of records associated with an identity of a vehicle driver, which are recorded by means of a control device according to the invention
- FIG. 2 shows a schematic illustration of a sequence of the calculation of the cumulative steering time interruption.
- a vehicle driver 7 communicates his identity 10 to a control device 8 by means of a data card 9 and, on the basis of this action, initiates, inter alia, the calculation of the cumulative steering time interruption ⁇ tj.
- the control device 8 is connected to a sensor 11, which communicates with the sensor Control unit 8 transmits a measured value f (v) correlated to the speed.
- the activity 1 changes after a longer duration of "work” to a 73-minute activity “sleep" (tu), which ends at the time or the time reference mark trefi.
- This is followed by a sequence of "steer” alternating with "readiness”.
- the cumulative driving time interruption ⁇ ti (ti 2 + ti4 + ti ⁇ ) is 79 minutes at the time t Re f2.
- the ab ⁇ closing interruption of tis 35 minutes results in ⁇ ti> 45 minutes, so that a new reference mark according to the invention (t Re f2) is set according to the inventive method to the end of the last summed period.
- the control unit 8 checks whether the determination of a reference mark t Re f (ID) has already taken place for the identity 10 in the past. For this purpose, the control device 8 accesses an internal first memory 20 in which an assignment 21 of identities ID to reference marks t Re f is stored. If this check has the result that no reference mark t Ref is present for the identity ID, the method according to the invention according to the exemplary embodiment proceeds to a step designated by 1. If a reference mark t Re f had previously been determined for the identity ID, which element is the assignment 21, the method is continued with the 2nd be ⁇ recorded step. The step denoted by 0. is basically not a prerequisite for the calculation of a cumulative driving time interruption ⁇ t t according to the invention pelg.
- step 1 of the method in ne ⁇ -t gativer time sequence starting from the present time t N examined whether a ununterbro ⁇ chene driving period interruption ti X is present within previous records, which lasted longer than 45 minutes. If such a period of 45 minutes or more, the inventive method according to the embodiment sets a timestamp t Re fi on the end ti xe , which limits this steering time interruption in a positive time sequence. If there is no period of uninterrupted driving time interruption of at least 45 minutes duration in the previous recordings, the reference mark t Ref i is set to the chronological beginning of the recordings to.
