Definitions
- a sensor arrangement for a belt drive and a method for determining a rotational position of belt pulleys are described here.
- Electric drives for steering motor vehicles are known, for example, for power steering systems (Electric Power Steering, EPS).
- EPS Electronic Power Steering
- a so-called "power pack” which includes a motor unit and a control or regulation in the form of an electronic data processing device (ECU)
- ECU electronic data processing device
- GKT ball screw drive
- the belt drive which couples the "power pack” or motor unit to the ball screw, usually has two pulleys and a belt.
- SBW fully electronically supported steering systems of motor vehicles
- inductive, capacitive, magnetic and/or optical sensors it is possible to use inductive, capacitive, magnetic and/or optical sensors to determine the rotational position of the pulleys of the belt drive, which couples the "power pack" or the motor unit to the ball screw drive, and thereby draw conclusions about the current track angle of the through to pull the wheels influenced by the steering.
- optically detecting sensors are unusual in practice due to contamination of the sensors and pulleys and/or due to a lack of accuracy. The most precise measurement results can be achieved with the help of inductive sensors.
- a problem with detecting a current or actual rotational position of the pulleys is that a specific rotational position of the two pulleys of the belt drive does not necessarily correspond uniquely to a specific toe angle of the wheels influenced by the steering. Consequently, based on a determination of the rotational positions of the pulleys, only the actual or current Toe angle of the wheels influenced by the steering can be determined if the detection of the rotational positions of the pulleys is supplemented by a sensor detection directly on the wheels or at least by an evaluation of the detection history of the rotational positions of the pulleys.
- the former involves additional technical effort and thereby puts into perspective the advantages associated with detecting the rotational position of the pulleys for regulating or controlling the steering.
- the latter requires that the detection history is always available, i.e. even when the motor vehicle starts, and that a memory always provides the history data at the same time as the sensor detection. If the recordings of past rotational position detections, for example when the motor vehicle starts moving, are not available, it is not possible to reliably determine a current toe angle of the wheels influenced by the steering based solely on the rotational position of the pulleys. Safe control of the motor vehicle is therefore not possible in this situation. Furthermore, for example, a tire change can lead to an interruption and/or falsification of a recorded detection history, which makes it impossible to subsequently reliably determine an actual steering angle based on a detected rotational position of the pulleys of a steering system.
- the belt drive has at least a first pulley with a first diameter and a second pulley with a second diameter. Furthermore, the belt drive has a belt, which is arranged on a lateral surface of the first and second pulleys and is designed to transmit a rotational movement of the first pulley to the second pulley.
- a first sensor arrangement is arranged and designed to detect a rotational position of the first pulley. Furthermore, a second sensor arrangement is arranged and designed to detect a rotational position of the second pulley.
- the first diameter corresponds to a first integer multiple of a unit length.
- a unit of length can be, for example, a millimeter, a centimeter, an inch or another measure of any length.
- the first pulley has a diameter whose length or amount can be specified as the product of a natural number with a selected measure of length, for example with a centimeter or with an inch or another measure of length of any length.
- the first pulley may have a diameter of 31 units of length, for example a diameter of 31 millimeters.
- the second diameter corresponds to a second integer multiple of the same unit length.
- the second pulley may have a diameter of 97 units of length, for example a diameter of 97 millimeters.
- the first and second integer multiples of the length unit are different from each other and coprime.
- 31 and 97 are different natural numbers that are coprime to each other, i.e. have no common natural divisor beyond the number 1.
- the size ratio between the first pulley and the second pulley and/or the length ratio between the first diameter and the second diameter corresponds to a ratio of two different natural numbers to one another, whereby the two different natural numbers do not have a common natural number have divisors other than the number 1.
- the first integer multiple and/or the second integer multiple can correspond to a prime number or the product of a first and/or second unit of length with a prime number.
- the diameter of the first and/or the second pulley can each correspond to a product of any length unit of any length and a natural number, in particular a prime number. This ensures that the first integer multiple and the second integer multiple of the unit of length can never have a common natural divisor.
- the first sensor arrangement can have a contactless position sensor, in particular a contactless and inductive position sensor.
- the second sensor arrangement can also have a contactless position sensor, in particular a contactless and inductive position sensor.
- the first and/or the second sensor arrangement can have a CIPOS® sensor that determines the rotational position of the first and/or second pulley.
- the first and/or the second sensor arrangement can each be arranged to determine a rotational position or a rotational position of a pulley. In other words, the first and/or the second sensor arrangement can each determine how many degrees a pulley has rotated relative to a defined or imaginary zero position or starting position.
- the belt drive can comprise a data processing device or can be assigned to and/or connected to a data processing device.
- the data processing device can in particular be an electronic data processing device.
- the data processing device can also be formed entirely or partially by the first and/or second sensor arrangement and/or by part of the first and/or second sensor arrangement or be integrated into these.
- the data processing device can evaluate and store the detection of the first sensor arrangement and/or the second sensor arrangement and/or the detections and/or the output. Make ratings of an external technical device, for example an on-board computer, accessible.
- the data processing device can be integrated into an on-board computer or can be designed as part of an on-board computer.
- the belt drive has a gear ratio of 97/31 or approximately 3.129 from the first, smaller pulley to the second, larger pulley.
- approximately 3.129 revolutions of the first, smaller, pulley causes one complete revolution of the second, larger, pulley.
- the reciprocal value results in a gear ratio of 31/97 or approximately 0.3196 from the second, larger pulley to the first, smaller pulley. In other words, approximately 0.3196 revolutions of the second, larger pulley causes one complete revolution of the first, smaller pulley.
- a specific rotational position or setting position of the belt drive which is defined by a specific rotational position of the first pulley and a specific rotational position of the second pulley, only repeats itself after 97 complete revolutions of the first pulley and 31 complete revolutions of the second pulley.
- Each combination of a specific rotational position of the first pulley and a specific rotational position of the second pulley can thus be uniquely assigned to a specific positioning position of the belt drive over an adjustment path comprising several complete rotations of the first and/or the second pulley.
- the belt drive described here can be used, for example, for steering a motor vehicle. This can, for example, have an axis-parallel arrangement with one of the belt drives described above.
- the belt drive can transmit a rotational movement from a first pulley arranged on an electric motor to a second pulley arranged on a ball screw, the ball screw being set up to convert the rotational movement into a translational movement to effect or support the steering.
- each combination of specific rotational positions can be assigned to exactly one positioning position of the belt drive, and thus clearly to a steering angle of the motor vehicle wheels.
- the adjustment path of the belt drive can be defined by 80 to 120, in particular by 90 to 110, maximum possible complete revolutions of the first pulley in a specific direction of rotation.
- the second integer multiple of the unit of length, which corresponds to the diameter of the second pulley, can be formed by the product of a natural number and the unit of length, where the natural number is greater than 80, in particular greater than 90 and/or greater than 100 and/or greater than 120, can be.
- the first pulley can be coupled to a motor or electric motor, in particular to the rotor of a brushless electric motor.
- control or regulation of the motor or electric motor can also be based on the detection of the first sensor arrangement.
- the brushless electric motor can be a permanent magnet synchronous motor (PMSM) or a brushless asynchronous machine.
- the detection of the first sensor arrangement can serve at least two different purposes, namely firstly a determination of the position of the belt drive on the travel and/or a determination of the steering angle of a steering system and secondly the regulation or control of a motor coupled to the belt drive or electric motor.
- the control of the motor can include, for example, field-oriented control, FOC.
- the belt drive can include a temperature sensor which is set up to detect a temperature of the belt drive, in particular a temperature of the area surrounding the belt.
- the belt drive can include a temperature estimator, which is set up to estimate a temperature of the belt drive, in particular a temperature of the belt's surroundings, based on a modeling of the belt drive.
- An advantage here is that based on the detection of the temperature sensor and/or the temperature estimator, a temperature compensation of the belt elasticity of the belt, in particular a first or second order temperature compensation, can be carried out.
- the data processing device can be set up to determine compression or expansion of the belt based on the detection of the first sensor arrangement and the second sensor arrangement and/or the temperature sensor and/or the temperature estimator.
- the data processing device can also be further set up to determine a force acting on the belt drive, in particular on the belt, based on the detection of the first sensor arrangement and the second sensor arrangement and/or the temperature sensor and/or the temperature estimator.
- the first sensor arrangement and the second sensor arrangement which can optionally be supplemented by a temperature sensor and/or a temperature estimator, can also work together to form a force sensor, for example a force sensor for the forces acting on the steering of a motor vehicle during a ferry operation of the motor vehicle.
- the acting forces can be determined by detecting compressions or expansions of the belt and comparing them with predetermined and/or stored reference values.
- the data processing device is further set up to detect wear and/or damage to the belt drive, in particular the belt, based on current and/or recorded detections of the first sensor arrangement and the second sensor arrangement and/or the temperature sensor and/or the temperature estimator determine or estimate.
- the data processing device can be set up to detect supercooling and/or icing of the belt drive and/or one coupled to the belt drive based on current and/or recorded detections of the first sensor arrangement and the second sensor arrangement and/or the temperature sensor and/or the temperature estimator Device, in particular a ball screw, to determine and / or estimate.
- Icing for example icing of the ball screw drive
- Icing of the belt drive and/or a device coupled to the belt drive can have a significant negative impact on the traffic safety of the motor vehicle.
- hypothermia and/or icing of the belt drive and/or a device coupled to the belt drive, in particular a ball screw drive can also occur
- Data processing device can be determined by comparing the detections of the first sensor arrangement and the second sensor arrangement and / or the temperature sensor with a modeling of the belt.
- the modeling can in particular be a virtual modeling of the belt drive created by the, in particular electronic, data processing device, which models technical-physical properties of the belt drive, which is then used by the data processing device with the actual detections of the first sensor arrangement and the second sensor arrangement and / or the Temperature sensor can be adjusted.
- the belt drive described above can in particular be part of an axis-parallel arrangement or an axis-parallel drive, in particular for the steering of a motor vehicle.
- the belt drive and/or the axis-parallel arrangement or the axis-parallel drive with the belt drive can also be part of a motor vehicle, in particular part of the steering of a motor vehicle.
- the data processing device can be further set up based on the determination of wear and/or damage and/or hypothermia and/or icing of the belt drive, in particular the belt, and/or with a device coupled to the belt drive, in particular of a ball screw, to issue a warning message to the driver of a motor vehicle and/or to shut down the motor vehicle.
- An advantage here is that, on the one hand, the driver of the motor vehicle can be informed that maintenance of the motor vehicle is foreseeably necessary, for example with a visually and/or acoustically perceptible warning message, and on the other hand, in the event of a dangerous situation being detected, the vehicle can also be shut down by the data processing device can be.
- a method for determining a rotational position of pulleys of a belt drive includes the steps:
- first diameter corresponds to a first integer multiple of a unit of length
- second diameter corresponds to a second integer multiple of the same unit of length, the first and the second integer multiple of the unit of length being different from one another and coprime with each other.
- the method for determining a rotational position of pulleys of a belt drive can include the following steps:
- FIG. 1 shows an example of a belt drive 100.
- Figure 1 shows an example of a belt drive 100 with a first pulley 10 and a second pulley 20.
- the first pulley 10 is rotatably mounted about a first axis of rotation XI and the second pulley 20 is rotatably mounted about a second axis of rotation X2.
- 1 further shows a belt 30, which is arranged on a lateral surface of the first and second pulleys 10, 20 and is designed to transmit a rotational movement of the first pulley 10 to the second pulley 20.
- the pulleys 10, 20, which are expressly not shown to scale, have a size ratio which corresponds to the ratio of two natural numbers that are coprime to one another.
- the rotational position of the pulleys 10, 20 is each detected with a sensor arrangement, each of which has at least one sensor.
- the rotation position of the first Pulley is detected with a first sensor arrangement (not shown) and the rotational position of the second pulley is detected with a second sensor arrangement (not shown).
- the first and second sensor arrangements are set up to determine a rotational position of the first pulley 10 and the second pulley 20.
- the first and second sensor arrangements determine by how many degrees the pulleys have rotated relative to a predefined zero position.
- the sensor arrangements each forward the detected rotational positions of the pulleys 10, 20 to an electronic data processing device (not shown).
- the data processing device uses the two rotational positions of the pulleys 10, 20 to determine an adjustment position of the belt drive on an adjustment path comprising several complete rotations of the first and second pulleys.
