Definitions
- the invention relates to an arrangement for contactless detection of the angle of rotation of a rotatable element, in particular a shaft of an internal combustion engine, in the evaluation of magnetically influenced electrical
- a magnet is connected to the rotatable shaft, the angular position of which is to be determined.
- the magnetic field which changes with the angle of rotation of the shaft, is measured using two sensor elements. These sensor elements are either two Hall sensor elements that are rotated against each other by an angle of 90 ° or two magnetoresistive ones
- Sensor elements that are rotated by 45 ° against each other.
- the sensor elements are supplied with alternating voltage signals that are phase-shifted in a suitable manner relative to one another.
- the superimposition of the output signals of the sensor elements results in a signal curve that is representative of the Angular position.
- an angle measurement over an angular range of 360 ° can be obtained.
- a special application of the known arrangement for contactless detection of the angle of rotation is the detection of the angular position of the camshaft of an internal combustion engine.
- the present invention in particular is intended to detect the angle of rotation of the camshaft of an internal combustion engine, the problem with camshaft angle detection will first be described below.
- a crankshaft is used with an encoder disk with 60-2 angular marks, which rotates with the crankshaft and is scanned by a sensor, a sensor being used as the sensor, which uses the inductive, magnetoresistive or Hall effect.
- NW position the absolute camshaft position
- the camshaft positions are recorded segment by segment.
- a disc that rotates with the camshaft and has, for example, an angle mark per cylinder, is scanned with the aid of a sensor.
- This sensor emits an output signal that has a pulse several times per camshaft revolution.This provides up-to-the-minute information about the camshaft position always at the segment limits, i.e. at the points where pulses occur in the camshaft sensor signal. In the angular positions between the segment boundaries, there is no absolute angular information regarding the camshaft position available.
- Continuous detection of the angle of rotation on the camshaft can improve the engine control system because the current angle information is available in the control unit at all times.
- the functionality of existing engine control functions can thus be improved and additional functions can be implemented if necessary.
- a quick diagnosis of the speed sensor can be carried out; simple and quick diagnosis of the absolute angle sensor itself is possible by checking the plausibility of the signal.
- safe and simple starter identifications can be carried out.
- the engine stalling as well as an underspeed can be reliably recognized, a direction of rotation detection is possible and faster synchronization during quick start processes can be realized.
- a better speed encoder emergency run is also feasible and a direct start of the motor is only possible using an absolute angle encoder.
- Such an absolute angle encoder with which the angular position of the camshaft can be determined at any time, can be obtained with the help of the present one
- an engine control system can be constructed which is characterized by a better quick start, as a result of which the battery, the starter and the alternator are subjected to less stress and can therefore be of smaller dimensions.
- Reliable detection of the direction of rotation makes it possible to avoid intake manifold sludge, for example, the intake manifold and the throttle valve of the engine can be specified with lower requirements.
- FIG. 1 shows the arrangement of the sensor elements in an example for detecting the angular position of a camshaft of an internal combustion engine.
- FIG. 2 shows signal profiles over an angle of 360 °.
- FIG. 3 shows a layout of a magnetoresistive angle sensor and
- FIG. 4 shows an associated evaluation circuit which is known from DE OS 1 95 43 562.
- FIG. 1 an embodiment of the arrangement according to the invention is shown.
- the angular position of the rotatable shaft 10, for example the camshaft of an internal combustion engine, is to be determined.
- a disc 11 With the shaft 10, a disc 11 is connected, the z. B. is cylindrical and has two magnets 12, 13 or a magnet, the poles of which are magnetically coupled via the disk, the polarity or arrangement of which is such that an approximately homogeneous magnetic field 14 is formed between the magnets. This magnetic field rotates with the shaft 10.
- the sensitive area of the fixed angle of rotation sensor 15 comprises the two sensor elements IC1 and IC2, which are located on a carrier 16.
- the rotation angle sensor 15 is held by means of a sensor holder 17.
- the sensor element IC1 contains a sensitive element, which uses the magnetoresistive effect to determine the angle between the magnetic field and the angle of rotation sensor. Since, due to the physical properties on which the magnetoresistive effect is based, the entire angular range of 360 ° cannot be covered, the sensor element IC1 detects two areas, each with 180 °. These ranges are referred to as the angular range W1 and the angular range W2 and are illustrated in connection with FIG. 2.
- the sensor element IC2 contains the evaluation circuit for the magnetoresistive element IC1 and also a sensitive unit that works according to the Hall effect. This sensitive unit is used to identify the areas in which the magnetoresistive element IC1 and also a sensitive unit that works according to the Hall effect. This sensitive unit is used to identify the areas in which the magnetoresistive element IC1 and also a sensitive unit that works according to the Hall effect. This sensitive unit is used to identify the areas in which the
- Angle sensor works, ie detection of the angular range W1 or the angular range W2. Sensitive units that work according to the Hall effect are described in more detail, for example, in DE OS 195 43 562.
- signal profiles are obtained as shown in FIGS. 2a and b.
- the signal curve that is to say the output voltage UM of the magnetoresistive element IC1
- the signal curve is proportional to the angle ⁇ and increases from 0 to a predetermined value.
- the signal jumps from the maximum value to zero and then rises again linearly up to an angle of 360 °.
- the Hall element IC2 supplies a digital voltage level UH after signal processing, with the signal processing being switched at the zero crossing of the sinusoidal Hall voltage UHS.
- the processed signal curve of the Hall element is accordingly between 0 and 180 ° high and between 180 ° and 360 ° low.
- a definite angle determination can be carried out in an angular range of 360 °.
- the voltage of the signal curve according to FIG. 2a corresponds to an angle which is between 0 ° and 180 °, 0 V corresponding to 0 ° and maximum voltage equal to 180 °. Due to the properties of the magnetoresistive effect and the evaluation circuit, this course is repeated twice within a complete revolution of the shaft (for example the camshaft). If the Hall element is designed so that a 1 is present at its digital output between 0 ° and 180 ° (signal is high) and a 0 (signal is low) at an angle between 180 ° and 360 °, a clear relationship between voltage and Make angles over the entire area.
- the result of the angle determination is ambiguous. In the case of a pure angle measurement, it is therefore necessary to suppress the measurement value acquisition in these areas.
- the arrangement according to the invention is used for contactless detection of the angle of rotation in connection with the determination of the angle of the camshaft of an engine, the ambiguity in the angle detection at the switchover limit only plays a role during the start-up phase of the engine Role. If the switching limits of the angle sensor are set so that they fall into the top dead center of the engine, then the ambiguity is no longer relevant in practice, since under normal conditions an engine does not stop at top dead center and therefore does not start from top dead center got to.
- the magnetoresistive sensor element consists of two individual elements which are rotated relative to one another by an angle of 45 ° and are coupled to one another via a connection.
- the two sensor elements have the corresponding connections and, as shown in FIG. 2b, can also be arranged one above the other.
- the two sensor elements are subjected to the voltages or
- the Hall element is not shown explicitly. It is housed on the same integrated circuit IC1 as the evaluation circuit.
- the Hall element can be designed in the simplest way, since it does not have to provide a linear characteristic curve, but merely serves to differentiate the angular ranges and is intended to deliver a digital output signal in which a 1 characterizes the angular range W1 and a 0 characterizes the angular range W2.
- the simple design and the combination with the evaluation circuit enables cost-effective implementation. Since magnetoresistive elements detect the magnetic field component in the direction of the chip plane and the Hall elements the magnetic field component perpendicular to the chip plane, the chip of the magnetoresistive element must be perpendicular to the chip of the Hall element. This arrangement is shown in Figure 1.
- chip IC1 with the magnetoresistive element and the chip IC2 with the evaluation circuit and the Hall element or the Hall elements can be created separately using different manufacturing processes, which enables effective manufacturing.
- chip IC2 thus means the Hall element, which is shown in FIG. 1 as a small rectangle and the evaluation circuit A shown below as a large rectangle.
- the separately manufactured chips are connected to each other by conductor legs that are bent by 90 °. This creates an easy-to-use unit for further processing.
- the separation of the magnetoresistive element and the evaluation circuit and the connection with lead pins enable optimal integration in the special integrated circuits IC1 and IC2.
