Definitions

  • the invention relates to a low-noise motor vehicle with features corresponding to the preambles of claims 1 to 3.
  • the operation of the engine via its injection pump is regulated by engine electronics, on the basis of data which are associated with a full-load line and a reduction line and are stored in a data memory.
  • engine electronics on the basis of data which are associated with a full-load line and a reduction line and are stored in a data memory.
  • engine operation occurs in various driving operating conditions, which causes sound radiation that is inherently higher than that of the legislative requirements, but is insulated accordingly by the upstream engine encapsulation.
  • the inventions take a different path.
  • the values of power and speed-reducing full-load lines and cut-off lines which values are at least partially different from those of the standard full-load line and cut-off line, are stored in free and / or additionally available data storage locations of the engine electronics.
  • the engine electronics are generally assigned an electronic control unit with a microprocessor, data and program memory, input and output peripherals, which is used to control the engine electronics in the sense of a noise-reducing operation of the engine.
  • this control unit calculates the vehicle acceleration in certain speed ranges in connection with the transmission setting from correspondingly signaled operating data and compares it with predetermined acceleration limit values stored in its data memory. If this is exceeded, the control unit then issues a command to a data storage selection circuit, which then causes a change to a correspondingly different data record (full load line and / or cut-off line), the values of which subsequently determine the setting of the injection pump in the sense of noise-reduced operation of engine 1 are.
  • a data storage selection circuit which then causes a change to a correspondingly different data record (full load line and / or cut-off line), the values of which subsequently determine the setting of the injection pump in the sense of noise-reduced operation of engine 1 are.
  • the path is followed in that the legally prescribed sound radiation limit values are to be specified immediately as setpoints and are used according to the invention in such a way that the engine can in principle never be operated in such a way that these sound limit values are exceeded.
  • control measures according to claims 1 and 2 are quasi linked, in the sense that the noise-reducing engine control measures are initiated when the predetermined limit values for acceleration and / or sound are exceeded.
  • the gear shifts so as not to throttle the driving operation in a noise-reducing engine operating mode, are carried out automatically by the engine electronics or a transmission electronics communicating with them.
  • the driver receives a visual and / or acoustic indication that he has to change gear and which gear when the control unit calls up a power and speed-reducing line to be able to continue driving the vehicle at the previously given speed or acceleration.
  • the measures according to the invention ensure in any case that the expensive engine encapsulations that were previously necessary can either be dispensed with entirely or at least replaced by comparatively inexpensive partial partitions.
  • the drive device of the motor vehicle consists of an engine 1, in particular a diesel engine, which acts on an axle drive train 3 via a transmission 2.
  • the engine 1 is supplied with fuel via an injection pump (not shown).
  • the operation of engine 1 and its power control via a corresponding setting of the injection pump can be controlled by engine electronics 4.
  • This has a microprocessor uP, a program memory PS, at least one data memory DS (FIG. 1) or DS 0, DS 1, DS 2 (FIGS. 2 and 3) and an input peripheral 5 and output peripheral 6.
  • the individual components of the motor electronics are linked to one another via a data bus system 7.
  • the engine electronics 4 works on the basis of a large number of current driving operation data or values reported by sensors / sensors, such as charge air pressure, charge air temperature, cooling water temperature, fuel temperature, accelerator pedal position, injection pump speed, injection pump control setting, engine speed, generator speed, axle drive train speed and the like.
  • sensors / sensors such as charge air pressure, charge air temperature, cooling water temperature, fuel temperature, accelerator pedal position, injection pump speed, injection pump control setting, engine speed, generator speed, axle drive train speed and the like.
  • the corresponding sensor system is largely summarized in a box labeled 8 to avoid confusion in the drawing in FIGS. 1 and 2. It goes without saying that the individual sensors in the motor vehicle are arranged at the corresponding signal pick-up locations on the relevant units / components.
  • the motor electronics 4 has a data storage capacity which either has enough free storage spaces for storing the data / values required for the control control according to the invention or is considerably expanded compared to that previously used to control the same drive unit, which - as can be seen in FIG. 1 by replacing the previously used data memory with a data memory DS designed for a higher storage capacity or - as can be seen from FIGS. 2 and 3 - by supplementing the previously used data memory DS 0 by at least one further data memory DS 1, DS 2 of the same or higher storage capacity can.
  • the data memory DS (FIG. 1) or DS 0 (FIGS. 2 and 3)
  • the limit values specifying the maximum engine power and maximum engine speed are stored, which are defined in FIG.
  • the values of power and speed-reducing full-load lines and cut-off lines which are different from those of the standard full-load line 9 and cut-off line, are stored in the additional memory locations of the data memory DS (FIG. 1) or the data memory DS 1, DS 2 (FIGS. 2 and 3) 10 are at least partially different and are used according to the invention for less noise-causing operation of the drive unit.
  • a number of such lines can be seen from the diagram in FIG. 4.
  • the values of the dotted first additional full load line 11 partially correspond to those of the full load line 9, but this is followed by a different stop line 12 compared to the stop line 10 with the same degree of reduction but a lower final stop speed.
  • This engine electronics 4 which is given in this way and is equipped with stored data / values, is assigned, according to the invention, an electronic control unit 19 which is used for recording and processing sound-relevant data / values and for controlling the engine electronics 4 in the sense of noise-reducing operation of the engine 1.
  • This control unit 19 comprises a microprocessor uP, a data memory DS, a program memory PS and an input periphery 20 and an output periphery 21. These components of the control unit 19 are linked to one another via an internal data bus system 22.
  • This control device 19 is used according to the invention for three different control versions.
  • the control unit 19 receives the actual values n M of the engine speed and v of the driving speed as well as a signal (gear) representative of the setting of the transmission or the gear engaged.
  • the control device 19 also receives from sensors 23, 24, which are arranged on the engine 1, possibly also on the transmission 2 and other locations in the engine compartment, the values representative of the noise development / sound radiation.
  • the control device 19 receives only the sound values detected by the said sensors 23 and 24.
  • the control unit 19 uses the program in the case of FIG. 1 to calculate the instantaneous vehicle acceleration given in certain speed ranges in connection with the transmission setting and compares these with predetermined acceleration limit values stored in its data memory DS and inputs them when they are exceeded Command to a data memory selection circuit 25, which then causes a change to a correspondingly different data record stored in the engine electronics 4, that is to say a full load line that was previously effective and / or a different than previously effective reduction line.
  • a data memory selection circuit 25 which then causes a change to a correspondingly different data record stored in the engine electronics 4, that is to say a full load line that was previously effective and / or a different than previously effective reduction line.
  • the control unit 19 compares the sound values detected and reported by the sesors 23, 24 with sound limit values stored in the data memory DS and, when exceeded, issues a command to the data memory selection circuit 25, which then changes accordingly another data record stored in the engine electronics 4, that is to say a full-load line other than that previously effective and / or a different regulating line than previously effective.
  • the control unit 19 calculates the current vehicle acceleration per program in the same way as in the case of FIG. 1 and compares it with predetermined acceleration limit values stored in its data memory DS.
  • control unit 19 in this case also compares the sound values (with 23, 24) recorded with the sound limit values stored in its data memory DS and, if the limit values for acceleration and / or sound are exceeded, gives one just as in the case according to FIGS. 1 and 2 Command to the data memory selection circuit 25, which then also here causes a change to a correspondingly different data record stored in the motor electronics 4, there in the data memory DS or DS1, DS2, that is to say a different full-load line and / or cut-off line that was effective before .
  • the data storage selection circuit 25 can, for example, as can be seen in FIG. 1, be integrated into the input periphery 5 of the motor electronics 4, or - as can be seen in FIG. 2 - can be attached to the input periphery 5 as a separate component outside the motor electronics 4, or - as from 3 can also be integrated into the output periphery 21 of the control device 19.
  • control unit 19 For the detection of which full-load line and / or de-regulation line is to take effect, control unit 19 emits signals with different voltage levels, which are interpreted accordingly by data storage selection circuit 25. Each of the differently high voltage levels is assigned a data set consisting of a full load line and a cut-off line, which is then called up and released by the data memory selection circuit 25 for processing in the engine electronics 4. With reference to the diagram according to FIG. 4, this means that either the full load line 9 with the cutoff line 10 or the full load line 11 with the cutoff line 12 or the full load line 13 with the cutoff line 14 or the full load line 15 with the cutoff line 16 or the full load line 17 with the Stop line 18 is retrieved.
