  • HMI human-machine interface
  • Modern engine controls are able to determine the operating point of a vehicle engine as well as the current fuel and fuel consumption. For example, using characteristic curves, it is possible to determine a particularly energy-saving operating point in the vicinity of the current operating point. In addition to other measures, this operating point can also be adjusted by adjusting the spray delivery without, for example, significantly changing the current speed.
  • the present invention By acting on the accelerator pedal, the present invention enables a method of guiding the driver upon actuation of the accelerator pedal to a more optimal operating point of the engine.
  • Such a procedure may be useful, for example, on motorways to bring the engine in an efficient torque range, possibly taking into account a smaller deviation in the speed. So that this deviation is not perceived by the driver of the vehicle as a loss of comfort, a maximum speed deviation from the current speed may possibly be specified, which is tolerated in the adaptation of the driving style. Even in the case of a convoy driving the fuel consumption can be significantly reduced in particular by achieving a uniform movement. By acting on the gas pedal, the driver can be given a reasonable speed resulting from the given situation, which he can easily keep to by following the set-up instructions for the gas pedal.
  • the driving style adapted to the current driving situation can consist, in particular, of setting a mean convoy speed, which is determined by a C2C or C2X communication (car-to-car or car-to-infrastructure communication).

  • the speed of the accelerator pedal operation is determined and brought into relation with the deflection.
  • a counterforce can be applied to the accelerator pedal via a low-pass filter integrated in the controller to make accelerating accelerating difficult.
  • such a function for acting on the accelerator pedal by the driver can be deactivated and coupled, for example, to the setting of an eco mode in the vehicle control.
  • the method proposed according to the invention can also be coupled with the already known hazard warnings by, for example, high-frequency action on the gas pedal position.
  • the controller determines a position of the accelerator pedal corresponding to the presettable spray delivery and compares it with a position sensor of the accelerator pedal and action on an adjusting device, for example by means of an electric motor to produce an at least release direction the accelerator pedal variable reaction force on the pressed by the driver from its rest position in the direction of actuation and against a restoring force accelerator pedal tries to adjust this position of the accelerator operated by the driver.
  • the opposite of the pressure of the driver on the accelerator pedal counterforce can be increased when an optimal accelerator pedal position is reached. If the driver exceeds this position when pressing the accelerator pedal, a further increase of the counterforce can take place, which causes the driver to relieve the pressure on the gas pedal. This allows the driver to be guided into an optimal accelerator pedal position.
  • control can also generate or generate a variable actuating force acting in the direction of actuation of the gas pedal.
  • the driver can also be actively stimulated to a stronger acceleration, if this requires a driving style adapted to the current driving situation.
  • the actuating force acting in the direction of actuation of the accelerator pedal and generated by the control is smaller than the restoring force of the accelerator pedal. This ensures that an acceleration of the vehicle can take place only when the accelerator pedal is actively actuated by the driver, but the driver is possibly excited to a greater acceleration.
  • the control according to the invention is thus such established that it tries to influence the driver to the appropriate setting of the accelerator pedal.
  • the mode of operation is similar to a conventional control: the deviation between the position of the accelerator pedal corresponding to the determined optimum injection flow and the current position of the accelerator pedal is determined in the sense of a system deviation.
