Definitions

  • the invention relates to a device for changing the actuation characteristics a power control device in motor vehicles.
  • actuation force is the actuation characteristic of a Power control element in the form of an accelerator pedal depending on the Vehicle speed and / or depending on the distance to the vehicle in front Vehicle changed. This change in actuation force however, only takes place in a certain operating state, for example if a specified distance to the vehicle in front is signed will, and will also automatically have no influence of the driver from a distance-related speed control system carried out.
  • driver request unit is a power control unit understood that is operated directly by the driver, such as that Accelerator pedal.
  • a performance control unit is defined as a performance adjustment unit understood that is operated indirectly by the driver, for example a throttle valve, the injection valves or electromechanical Valve trains.
  • a power setting unit is usually dependent from the actuation of a driver request unit and / or from operating variables of the motor vehicle through electronic motor vehicle control units operated.
  • a manually operated selection control element can, for example, be a Be a button for the direct selection of a desired actuation characteristic can be operated arbitrarily by the driver.
  • Selection of the actuation characteristic can also be one of one currently selected driving mode, for example all-wheel drive Switching unit can be provided, which automatically the actuation characteristics according to the selected driving mode, however indirectly the driver's request according to the selected driving mode reproduces.
  • This invention enables an optimal adjustment of the actuation characteristics possible from performance control bodies to the driver's request.
  • control unit 1 for example an internal combustion engine control unit.
  • the engine power in modern motor vehicles is usually increasingly controlled electronically by means of an internal combustion engine control unit.
  • the power setting unit for example a throttle valve
  • the driver's request specification unit for example an accelerator pedal.
  • a corresponding voltage signal is now forwarded to the internal combustion engine control unit by means of a pedal value transmitter on the accelerator pedal depending on the actuation of the accelerator pedal.
  • the internal combustion engine control unit controls the power setting unit accordingly.
  • the force (F) - pedal travel (PW) - characteristic curve of the accelerator pedal is usually matched by means of springs and hysteresis elements in such a way that an average favorable operating characteristic results.
  • a disadvantage of these existing systems is that the basic operating characteristics cannot be changed.
  • different actuation characteristics depending on different driving situations may be desirable for the driver.
  • the driver can be in four-wheel drive mode, in particular when driving off-road "drive, an increased accelerator pedal actuation force.
  • the different driving situations in the motor vehicle can be recognized in the vehicle by selectable driving modes, for example all-wheel operation or driver type (sporty or economical) and can be taken into account by the driver.
  • a first input signal of the control device 1 is the output signal of a manually operated selection control element 2 in the form of a selection button.
  • the driver can use the selection button 2 to select either the operating characteristic h ( hard ") or w ( soft ").
  • h hard
  • w soft "
  • control unit 1 receives the output signal of a switching unit 5.
  • Switching unit 5 is switched from a driving mode that is currently selected Normal "or All-wheel drive ". Is the driving mode Four-wheel drive mode "is selected, there is an indirect driver request for the selection of the actuation characteristic h, otherwise the driver's request for the selection of the actuation characteristic w is inferred. If both the selection control element 2 and the switching unit 5 are provided, the selection control element 2 preferably has the higher priority.
  • a pedal force map 6 is in control unit 1 and stored a throttle valve map 7.
  • the pedal force map 6 determines depending on the selected actuation characteristic h or w is the ratio of the actuation force F to the actuation path PW Driver request specification unit 3 in the form of an accelerator pedal.
  • the two different actuation characteristics have an exemplary embodiment also different hysteresis.
  • the throttle map 7 determines depending on the selected operating characteristic h or w is the ratio of the actuation path PW of the accelerator pedal 3 to the actuation path DW of the power setting unit 4 in the form of a Throttle. Depending on the selected characteristics of the selected actuation characteristic h or w from the control unit 1, the actuator for the pedal force adjustment of the Accelerator pedal 3 and the actuator of the throttle valve 4 controlled.
  • the driver must always apply a higher actuation force F for the actuation of the accelerator pedal than for the actuation characteristic w ( soft ").
  • This is advantageous, for example, when in four-wheel drive mode during a off-road “driving, it may not be possible to precisely dose the actuation force F due to hard footwear
  • Soft "actuation characteristics are desirable if, in particular, comfortable driving situations are present, for example, even with light footwear.
  • pedal force map 6 either alternatively or in addition to the throttle valve map 7 can be used can.
  • This embodiment according to the invention in particular the comfort of a vehicle increases. if poor dosing is present when the driver request specification unit is actuated.
