Definitions
- the invention relates to a method for adjusting a gain of a built-in magnetic field sensor, in particular a rotor position sensor of an electric motor, in which a magnetic field signal of the magnetic field sensor is removed and evaluated by an evaluation unit, and a device for adjusting a gain in a magnetic field sensor for operating an actuator.
- a method and a device for determining egg ner position of an electric motor are known, in which a position signal of a rotor of the electric motor is removed by a magnetic field sensor and is evaluated by an evaluation unit with respect to the position of the electric motor.
- the magnetic field-sensitive sensor is formed nikationsschnittstelle with a digital Lichtu, wherein in the sensor, a small microprocessor is integrated, which communicates via a digital interface with a microprocessor of the evaluation Kasu unit.
- amplification of the magnetic field signal of the magnetic field-sensitive sensor can be varied within an operation of the actuator by means of this embodiment, two micro-controllers are used, which causes higher costs and is detrimental to the functional safety of the system.
- a sensor with an analog interface may be used, but all tolerances of all possible embodiments of actuators must be taken into account for calculating the slope for gain adjustment.
- the gain can not reliably precede each actor. Too large a slope with an actuator with a very small air gap can bring the sensor into saturation. Too low a slope can cause a very poor signal-to-noise ratio with a weak useful signal.
- the invention has for its object to provide a method and apparatus for adjusting a gain of a built-in magnetic field sensor, wherein at least least the static tolerances of an actuator system between the magnet and magnetic field sensor can be corrected.
- the object is achieved in that the evaluation unit positioned on a printed circuit board outputs a signal for gain adjustment to the magnetic field sensor positioned on the same printed circuit board after evaluation of the magnetic field signal of the magnetic field sensor.
- This has the advantage that at any time set different gains and thus changing static tolerances between the magnet and the magnetic field sensor can be corrected by an adjusted gain setting, although magnetic field sensor and evaluation are installed on a common circuit board.
- This adaptation is particularly advantageous since the gain of the sensor signal is adjusted, even if the evaluation unit can not provide any programming voltage.
- the gain adjustment signal is coarsely adjusted in a first step and finely adjusted to a second step.
- a coarse adjustment can take place during the commissioning of the actuator, since approximately the value of the magnetic field signal of the magnetic field sensor is known.
- the second step can be over the life of the sensor is set to correct a magnetic field decrease of the magnetic field to be sensed span magnet over a period of time.
- a maximum magnetic field signal is determined at a minimum distance of the magnetic field sensor to a magnetic field generating element and at a predetermined temperature. This will be an ideal gain be true that does not exceed a predetermined range.
- the first step after initial installation of the magnetic field sensor is performed in an actuator. Thus, a starting point for the adjustment of the actuation for controlling, for example, a clutch actuator is made possible.
- the second step is carried out in a rest state of the actuators during loading operation of the actuator in a drive system.
- a rest situation in which, for example, no force is exerted on the mechanical parts of the actuator, an adjustment of the gain to form a maximum Magnetfeldsigna- les easily perform.
- a current magnetic field signal of the magnetic field sensor is measured by the evaluation and compared with the maximum magnetic field signal in the idle state of the actuators, wherein the signal for gain adjustment is set depending on the comparison.
- a sinusoidal component and a cosine component of the magnetic field signal of the magnetic field sensor is evaluated by the evaluation unit, wherein a first signal for gain adjustment of the sine component and a second signal for ampli kung adjustment of the cosine component to the Magnetic field sensor is given via one channel.
- the gain at the magnetic field sensor can also be set if the magnetic field sensor is not arranged parallel to the axis of rotation of the electric motor. In this case, the gain components are unequal in size, but can be set in the magnetic field sensor to the maximum of each of the individual components.
- a development of the invention relates to a device for setting a gain to a magnetic field sensor for operating an actuator, wherein the actuator is actuated by an electric motor and comprises a rotor position sensor for determining a position of a rotor of the electric motor formed magnetic field sensor, wherein the magnetic field sensor with egg ner evaluation for determining the position of the rotor of the electric motor is connected from a magnetic field signal of the magnetic field sensor.
- the magnetic field sensor and the magnetic field sensor output from the magnetic field sensor signal is a signal for gain adjustment determining evaluation positioned in the actuator on a common circuit board, wherein an electrical Connecting channel between the evaluation unit and an unused connection of the magnetic field sensors, the signal for gain adjustment of the evaluation unit to the magnetic field sensor can be transmitted.
- the evaluation unit evaluating a sine component and a cosine component of the magnetic field signal are connected via a first electrical connection channel to a first unused terminal of the magnetic field sensor for transmitting the first signal for gain adjustment of the sine component of the magnetic field signal and a second electrical connection channel to a second one unused terminal of the magnetic field sensor for transmitting the second signal of the gain adjustment of the cosine component of the magnetic field signal connected. Since the amplification values for the sine or cosine component in the evaluation unit are known, a simple presetting can thus be made possible, whereby these amplification components can be taken into account in the angular calculation of the rotor from the two components.
- the magnetic field sensor has an analog interface to the connec tion with the evaluation unit.
- an analog signal can be easily transmitted from the evaluation unit to an unused port of the magnetic field sensor.
- FIG. 1 an embodiment of the device according to the invention is shown, as used for example as a clutch actuator in a clutch actuation system of a vehicle.
- the clutch actuator 1 consists of a housing 2, the cover with a housing 3 is completed.
- an electric motor 4 is arranged, which drives a Planetendoilzgetriebe 5, the Planeten currylzSystem 6 in a threaded spindle 7 engage, whereby the rotational movement of the electric motor 4 in an axial BEWE movement of the threaded spindle 7 is converted.
- the magnetic field sensor 9 is in operative connection with a magnet 11, which is fastened radially at a tip of the threaded spindle 7, which faces away from the Planetendoilzgetriebe 5, is fastened.
- such an actuator is considered in which both the magnetic field sensor 9 and the evaluation unit 19 are installed on the same circuit board 8 and the installation of the printed circuit board 8 takes place before the start of the magnetic field sensor 9.
- a gain of the output from the magnetic field sensor 9 magnetic field signal using the evaluation unit 10 is corrected in the installed state.
- a connection 15 between an analog output 12 of the Auswer teiki 10 and an uncontacted input 13 of the magnetic field sensor 9 is produced, via which a signal for gain adjustment to the magnetic field sensor 9 is supplied.
- the initial gain setting takes place during the commissioning process of the actuator.
- the rotor is moved in the form of the threaded spindle 7 and at the output U outi of the magnetic field sensor 9, a corresponding magnetic field signal is sent to the evaluation unit 10.
- This magnetic field signal corresponds approximately to a maximum magnetic field signal, which is held in the evaluation unit 10 as a threshold value.
- the evaluation unit 10 determines an ideal gain. This ideal gain is taken in the new state of the magnetic field sensor 9 at approximately 25 °, with a minimum distance of the gear spindle 7 and magnet 1 1 is assumed. This gain setting is stored in the evaluation unit I O and forwarded via the analog output 12 to the magnetic field sensor 9.
- the actuator 1 may lead to a magnetic field decrease over the life of the magnet 11, which is compensated by the adjustment of the gain of the magnetic field signal of the magnetic field sensor 9.
- This amplification determination is carried out in a quiescent situation of the actuator 1, in which no mechanical forces on the threaded spindle 7 act.
- the magnetic field signal emitted by the magnetic field sensor 9 is evaluated by the evaluation unit 10 and compared with the stored during commissioning maximum magnetic field signal. From the difference between these two signals, a signal for gain adjustment is determined, which is forwarded via the analog output 12 to the analog sensor input 13 of the magnetic field sensor 9, wherein the magnetic field sensor 9 amplifies the magnetic field signal accordingly.
- the gain has two amplification factors which are not equal.
- the sinusoidal component and the cosine component of the magnetic field signal are evaluated separately from the evaluation unit 10 and compared individually with a predetermined amplification.
- the gain values for the cosine signal and the sinusoidal signal are transmitted to the magnetic field sensor 9 on various transmission channels not further illustrated, each gain channel being input to a not further used input 13 of the magnetic field sensor 9.
- the gain of the magnetic field signal of the magnetic field sensor 9 can be varied accordingly, whereby a reliable position determination of the threaded spindle 7 of the actuator 1 is possible.
