Definitions
- the present invention relates to a method for vibration damping of a torque of a drive train according to claim 1, a drive system for a vehicle according to claim 2, and a vehicle according to claim 5.
- the object of the present invention is to propose an improved method for vibration damping of a torque of a drive train, in particular to propose an alternative to the known methods.
- this object is achieved by a method according to claim 1, according to which a method for vibration damping of a torque of a drive train is provided, the drive train having an electric motor with a speed sensor and an engine control unit, a damping control device, a device for determining the target torque of the electric motor and at least one Vehicle wheel comprising a speed sensor, wherein the damping control device comprises a first calculation device, a high-pass filter, a controller and a second calculation device, the following method steps being carried out:
- the controller determining a value for a compensating torque for damping vibrations and outputting the value for a compensating torque for damping vibrations to the second calculation means;
- V determining a value of a compensated target engine torque from the second calculation means and outputting the value of a compensated target engine torque to the engine controller.
- the target torque is adjusted so as not to induce any shaft vibration.
- the in-phase component of the shaft vibrations is removed by modifying the motor's target torque and ensuring that the motor does not induce resonance on the shaft.
- the vibrations are intended to dampen the vibrations caused by the inertia and stiffness of the powertrain after a sudden change in torque demand by modulating the engine torque.
- the vibrations should be dampened in a certain frequency range between 10Hz and 30Hz in order to avoid excessive vibrations.
- a drive train comprises an electric motor with a speed sensor and an engine control unit, a damping control device, a device for determining the target torque of the engine and at least one vehicle wheel with a speed sensor, with a damping control device being provided, comprising a first calculation means, a high-pass filter, a controller and a second calculation means.
- the device for determining the setpoint torque can be an accelerator pedal, in particular if only one electric motor is provided. Further advantageously, the arrangement according to the invention can comprise several electric motors in order to obtain a better average speed of the vehicle wheels.
- the damping control device is set up to carry out the method according to the method described above.
- the drive train is set up particularly advantageously in a motor vehicle.
- FIG. 1 shows a schematic representation of a damping control device for carrying out the method according to the invention
- FIG. 2 shows a drive system according to the invention with a drive train for a vehicle
- FIG. 3 shows a motor vehicle according to the invention.
- a vehicle in particular a motor vehicle, includes, among other things, a drive system.
- the drive system for the vehicle essentially comprises a drive train, a damping control device 2 and a device 3 for determining the target torque.
- the drive train essentially comprises an electric motor 1 and a vehicle wheel 4. If necessary, the drive train can also comprise a transmission 13 and/or a shaft 14. The vehicle wheel 4 is preferably driven by the electric motor 1, in particular via the intermediate transmission 13 and/or the shaft 14.
- the drive system preferably also includes a speed sensor 11 for determining the speed of the electric motor 1 and an engine control unit 12 for controlling the electric motor 1.
- the drive system also includes a vehicle wheel 4 with a speed sensor 41.
- a torque of the electric motor 1 which is to be transmitted to the vehicle wheel 4 , is requested via the device 3 for determining the target torque of the motor. Ultimately, this requirement comes from the driver of the vehicle who wants to accelerate the vehicle.
- a target torque value 28 is transmitted by the device 3 for determining the target torque.
- the damping control device 2 is provided to reduce undesired vibrations of the drive train.
- it is intended to dampen the vibrations caused by the inertia and stiffness of the powertrain after a sudden change in torque demand by modulating the engine torque.
- the vibrations should be dampened in a certain frequency range between 10Hz and 30Hz in order to avoid excessive vibrations.
- the damping control device 2 essentially comprises a first calculation device 21, a high-pass filter 22, a controller 23 and a second calculation device 24.
- 1 shows a diagram of the control and signal flow of the drive train, in particular of the damping control device 2.

- the engine speed is detected by the speed sensor 11 of the electric motor 1.
- the wheel speed is detected by the speed sensor 41 of the wheel 4.
- the result of this comparison is a value for the estimated or calculated twisting speed, which is also known as an estimated or calculated twisting 25 of the drive train can be referred to as the difference between engine speed and wheel speed.
- the estimated or calculated torsion 25 of the drive train is supplied to the high-pass filter 22 in a next method step.
- the high-pass filter 22 filters out correspondingly low frequencies from the twisting of the drive train signal 25 and feeds the remaining high frequencies to the controller 23 as a high-frequency value 26 of the twisting of the drive train.
- the controller 23 determines a value 27 for a compensation torque for damping vibrations.
- the compensation torque 27 for damping vibrations and the originally desired engine torque 28, which is detected by the device 3 for determining the desired torque are summed in the second calculation device 24 and sent to the engine control unit 12 as a value 29 for a compensated engine Desired torque derived.
