Definitions

  • the invention relates to a device for reducing vehicle longitudinal dynamics instabilities according to the preamble of claim 1.
  • the vehicle longitudinal dynamics instabilities are manifested in the fact that, during arbitrary acceleration, actuation of the accelerator pedal also causes undesired periodic changes in acceleration.
  • the accelerations are transmitted to the driver, who thus causes an undesired change in the position of the accelerator pedal.
  • the entire vibration system which includes the vehicle with elasticities in the drive train, masses to be accelerated and moments of inertia as well as the power output of the internal combustion engine according to the operating point in the torque / speed characteristic and other factors, can be dynamically unstable. This can lead to an oscillation in which, in extreme cases, almost the entire accelerator pedal travel is involuntary (Bonanza effect).
  • the invention is therefore based on the object of providing a device which effectively reduces the harmful effects of the longitudinal dynamics instabilities of the vehicle independently of the point of attack of the interference, the parameters of which can be set uncritically and the response. behavior of the internal combustion engine on arbitrary accelerator pedal actuation not noticeably worsened.
  • the solution is based on the principle that a suitable signal is derived from the engine speed, which signal is fed back to the positioner of the fuel-air mixture Y in the sense of regulation to a minimal jerk of the vehicle.
  • the speed changes of the motor are recorded and if they are disturbing, i.e. not recognized by the driver as being triggered arbitrarily, implemented in opposite position changes of the actuator.
  • arbitrary accelerator pedal changes by the driver are not dampened by the device.
  • this damping of the vehicle longitudinal dynamics instabilities is carried out by electrical means, by deriving electrical voltage from the engine speed, which is then differentiated and transmitted via a limiter amplifier.
  • this limiter amplifier is expediently limited to approximately 50% of the working range of the adjustment of the actuator. This ensures reliable compensation of interference vibrations, on the other hand the compensation does not have a disadvantageous effect on the driver's arbitrary acceleration and deceleration processes.
  • This device is particularly advantageously combined with a conventional device for electrical adjustment of the actuator by the accelerator pedal.
  • the signal emitted by the limiter amplifier is expediently coupled in at the output of the device for electrical adjustment of the actuator by the accelerator pedal (E-gas).
  • the output signal of the limiter amplifier is coupled into the signal flow path of the E-gas device at a coupling point 11.
  • This device has proven to be particularly advantageous in connection with diesel engines which, due to their soft suspension in the vehicle and their characteristics, cause longitudinal dynamics instabilities in the vehicle.
