Definitions
- the invention relates to a method for determining a state of motion of a clutch actuator in a vehicle, the clutch actuator being driven by an electric motor.
- Methods for determining the state of motion of a clutch actuator are known. For example, the standstill at a stop can be recognized as a movement state of the clutch actuator with an incremental sensor. Due to measurement inaccuracies in the known method, it is necessary to carry out a check of the specific movement states at regular intervals, so that a recalibration is possible.
- the object of the invention is to specify a method for determining a state of motion, which enables the aforementioned procedure. Furthermore, the task is based on the measurement of the armature resistance to implement a position reinitialization in the clutch actuator simply and reliably.
- a method according to the invention is proposed in which the armature resistance R A of the electric motor is determined in a stationary state of the electric motor, the armature resistance R A and the applied motor voltage U and the measured motor current I Motor-induced current nd and / or an induced voltage li ⁇ n _ can be calculated, and the motion state of the clutch actuator is determined from the induced current lind and / or the induced voltage U ⁇ n d, which are proportional to the engine speed n. In this way, a position of the clutch actuator can be recognized.
- the motor current I can preferably be used as a function of the speed n to determine a state of motion.
- a current induced by the motor rotation is used as a signal in this context: ⁇ u ind . u
- I motor current on the electric motor
- the voltage Uin d induced in the electric motor is also proportional to the motor speed n and can be calculated using the following equation:
- the armature resistance R A depends in particular on the temperature of the armature windings.
- aging effects due to wear of the brushes, e.g. B. carbon brushes on the commutator occur. It is therefore advisable to measure the armature resistance RA at regular intervals.
- the armature resistance is measured when the clutch actuator is stationary. Preferably with the electric motor stopped. To determine when the electric motor is really stopped, it is advantageous to use a clutch actuator with a self-locking gear. In the case of a self-locking transmission, there is a braking torque which counteracts any engine torque M. If the torque (U ⁇ I ⁇ M) generated by the motor voltage U is less than the braking torque of the transmission, plus the friction in the motor, the motor stops despite the voltage U being applied.
- the armature resistance R A can then be determined by a current measurement at a known voltage U. Possible inaccuracies in the measurement of a small current I can be averaged over time, e.g. B. by a hardware low pass or numerically in the control unit. Since the motor is in a steady state, the armature inductance is not taken into account in the measurement.
- the armature resistance R A can be measured in any position of the clutch actuator. Furthermore, the thermal load on the motor is advantageously kept low.
- the method according to the invention can preferably be used in a clutch actuator with incremental displacement measurement.
- the clutch actuator can be recalibrated at regular intervals or shortly before the armature resistance R A is required, namely for position reinitialization.
- the state of motion of the clutch actuator can be recognized on the basis of the motor current I.
- This signal is independent of the applied motor voltage U.
- the signal can only be influenced by the armature inductance if there are large changes in current. In this way, through the inventive method z. B. a standstill of the engine or the clutch actuator can be detected.
- the exact position can preferably be determined on a
- the induced current lin d which is proportional to the engine speed, can thus be calculated from the above equations.
- Runflat strategy z. B. to develop in the event of a failure of the incremental encoder. Since the measurement of the armature resistance RA is required to compensate for changes in the armature resistance R A ZU, the causes of these changes can thus also be determined indirectly by the method according to the invention.
- the engine temperature can also be determined by measuring R A. At least the voltage U can be selected with known armature resistance R A in such a way that the desired current, and thus the desired torque, results on the motor. This is e.g. B. for switch motors of interest. Here, however, the procedure for measuring the armature resistance should be adapted, since no self-locking gear is used.
- a device for measuring the armature resistance at low voltages can be used to recalibrate the speed measurement with the motor current on the clutch actuator.
