Abstract:
A method of avoiding bucking oscillations during acceleration of a vehicle by influencing a position of a throttle valve of the vehicle as engine torque trends between a lower initial torque value and an upper target torque value by changing the position of the throttle valve between an initial closed position corresponding to the initial torque value and a target opening position corresponding to the target torque value wherein a trend of the throttle valve position has a local maximum that opens the throttle valve adjacent to the initial closed position and a local minimum that closes the throttle valve between a local maximum and the target opening position, setting the position of the throttle valve with an electrically actuated control element, controlling the trend of the throttle valve position by a current function that actuates the electrically actuated control element, the current function controlling the trend of the throttle valve position so that it rises to the local maximum from the initial closed position, then drops to the local minimum, and finally rises to the target opening position.
