Abstract

A device and a method for controlling a drive unit of a vehicle. Starting from the position of an operating element, a power determining signal may be preselected. The actuator element is controlled as a function of a filtered power determining signal. The signal is filtered with a filter having at least one high-pass filter and one low-pass filter connected in parallel. The filtering is performed so that the filtered signal has at least one corresponding pulse in a transition to a modified signal.

Claims

1. A method of controlling a drive unit of a vehicle having an actuator element for influencing power provided to the drive unit, the method comprising:

determining a power determining signal from a position of an operating element of the drive unit of the vehicle;

filtering the power determining signal with a filter, the filter including at least one high-pass filter and at least one low-pass filter connected in parallel; and

controlling the actuator element of the drive unit of the vehicle as a function of the filtered power determining signal.

2. The method according to claim 1, wherein the filtered power determining signal has at least one pulse that corresponds in direction to a direction of a change in power derived from the power determining signal.

7. The method according to claim 1, wherein the operating element of the drive unit of the vehicle includes at least one of an acceleration pedal of the vehicle and a rotary potentiometer.

8. The method according to claim 1, wherein the actuator element of the drive unit of the vehicle includes at least one of a fuel metering device and a solenoid valve.

3. A method of controlling a drive unit of a vehicle having an actuator element for influencing power provided to the drive unit, the method comprising:

determining a power determining signal from a position of an operating element;

filtering the power determining signal with a filter, the filter including at least one high-pass filter and at least one low-pass filter connected in parallel; and

controlling the actuator element as a function of the filtered power determining signal;

wherein the at least one high-pass filter includes first and second high-pass filters connected in parallel.

4. The method according to claim 3, wherein signals of at least one of

i) both the first and second high-pass filters, and

ii) the low-pass filter are phase-shifted relative to one another.

5. A device for controlling a drive unit of a vehicle having an actuator element for influencing power provided to the drive unit, comprising:

a quantity input determining unit for determining a power-determining signal from a position of an operating element of the drive unit of the vehicle; and

a filter unit coupled to the quantity input determining unit, the filter unit including at least one high-pass filter and one low-pass filter connected in parallel, the filter unit filtering the power-determining signal output from the quantity input determining unit,

wherein the actuator element of the drive unit of the vehicle is controlled as a function of the filtered power-determining signal.

6. The device according to claim 5, wherein the filtered power-determining signal has at least one pulse that corresponds in direction to a direction of a change in power derived from the power-determining signal.

9. The device according to claim 5, wherein the operating element of the drive unit of the vehicle includes at least one of an acceleration pedal of the vehicle and a rotary potentiometer.

10. The device according to claim 5, wherein the actuator element of the drive unit of the vehicle includes at least one of a fuel metering device and a solenoid valve.

11. A device for controlling a drive unit of a vehicle including an actuator element for influencing power provided to the drive unit, comprising:

a quantity input determining unit configured to determine a power-determining signal from a position of an operating element of the drive unit of the vehicle; and

a filter unit coupled to the quantity input determining unit, the filter unit including at least one high-pass filter and one low-pass filter connected in parallel, the filter unit configured to filter the power-determining signal output from the quantity input determining unit;

wherein the actuator element of the drive unit of the vehicle is configured to be controlled as a function of the filtered power-determining signal.

12. The device according to claim 11, wherein the filtered power-determining signal has at least one pulse that corresponds in direction to a direction of a change in power derived from the power-determining signal.

13. The device according to claim 11, wherein the operating element of the drive unit of the vehicle includes at least one of an acceleration pedal of the vehicle and a rotary potentiometer.

14. The device according to claim 11, wherein the actuator element of the drive unit of the vehicle includes at least one of a fuel metering device and a solenoid valve.
